Chaputala 1: Chiyambi: Kukwera kwa 150kW DC Fast Charging mu Global EV Landscape

Kusintha kwa dziko lonse lapansi kupita ku kayendedwe ka magetsi sikulinso chizolowezi chokhazikika koma ndi mizati yayikulu ya mfundo zanyengo yapadziko lonse komanso njira zamafakitale. Pamene ziletso za injini zoyaka moto (ICE) zikuchulukirachulukira m'misika yayikulu komanso kugwiritsa ntchito magalimoto amagetsi (EVs) kwa ogula kukuchulukirachulukira, kufunikira kwa zomangamanga zolimba, zodalirika, komanso zothamanga kwambiri kwafika pachimake. Pakati pa zida zamagetsi zoperekera magetsi (EVSE), chojambulira chachangu cha 150kW DC chakhala "malo abwino" kwa ogwira ntchito zamalonda, oyang'anira magalimoto, ndi ogulitsa zinthu zapagulu.

Mosiyana ndi ma charger a AC otsika mphamvu omwe ndi oyenera kugwiritsidwa ntchito usiku wonse m'nyumba, kapena ma charger a 350kW+ amphamvu kwambiri omwe pakadali pano amasungidwa magalimoto apamwamba apamwamba komanso magalimoto atali, siteshoni ya 150kW imapereka njira yoyenera. Imapereka nthawi yosinthira mwachangu kwambiri kuposa mayunitsi a 50kW - nthawi zambiri imadzaza 80% ya batri yamakono ya EV mkati mwa mphindi zosakwana 30 - pomwe ikusungabe malo ofunikira komanso gridi. Izi zimapangitsa kuti ikhale yoyenera kwambiri pa malo operekera mafuta pamsewu, malo ogulitsira, komanso malo okhala m'mizinda "odzaza mwachangu".

Komabe, kusankha chojambulira choyenera cha 150kW si nkhani yosankha mtundu kuchokera pa kabukhu kokha. Zimaphatikizapo kumvetsetsa bwino zamagetsi zamagetsi, ukadaulo woziziritsa, njira zamapulogalamu, ndi njira zachuma. Chipangizo chosasankhidwa bwino chingayambitse ndalama zambiri zokonzera, nthawi zambiri sichigwira ntchito, komanso kutha ntchito mwachangu pamene ukadaulo wa batri ukusintha. Bukuli limagwira ntchito ngati njira yodziwira bwino dziko la 150kW DC fast charging, kupatsa ogula chidziwitso chofunikira kuti azitha kuyendetsa bwino zovuta pakusankha, kukhazikitsa, ndi kugwira ntchito kwa nthawi yayitali.

Tidzafufuza chifukwa chake modularity ndiye maziko a kapangidwe kamakono ka ma charger, momwe kasamalidwe ka kutentha kapamwamba kamatetezera moyo wa zida, komanso momwe kuphatikiza ndi Open Charge Point Protocol (OCPP) kumathandizira kuti ndalama zanu zikhale zosinthika komanso zogwirizana. Kuphatikiza apo, tidzasanthula mitundu ya ndalama zomwe zimapangitsa kuti masiteshoni a 150kW akhale bizinesi yothandiza, kuyang'ana kupitirira kugulitsa kwa kilowatt-ola limodzi kupita ku ntchito zowonjezera phindu ndi chithandizo cha gridi.

Mutu 2: Kusankha Kwaukadaulo: Kufotokozera Mzere wa 150kW Wogwiritsidwa Ntchito Pamalonda ndi Pagulu

Poyesa chojambulira chachangu cha 150kW DC, choyamba chomwe chiyenera kuganiziridwa ndi luso lenileni la kutumiza pa malo olumikizirana magalimoto. Si ma charger onse a "150kW" omwe amapangidwa mofanana. Mphamvu yoyesedwa nthawi zambiri imakhala yokhazikika pamalingaliro pokhapokha ngati pali magetsi enaake komanso momwe zinthu zilili panopa. Kwa wogula, kumvetsetsa kuchuluka kwa magetsi—nthawi zambiri kuyambira 200V mpaka 1000V—n'kofunika kwambiri. Ma EV amakono, monga omwe amamangidwa pa zomangamanga za 800V (monga Porsche Taycan, Hyundai IONIQ 5, Kia EV6), amafunikira ma charger omwe amatha kukhala ndi magetsi ambiri kuti afike pa liwiro lawo lalikulu lojambulira. Chojambulira cha 500V chimavutika kupereka 150kW ku magalimoto atsopanowa, zomwe zimalepheretsa magwiridwe antchito.

Mbali ina yofunika kwambiri posankha ndi kuthekera kwa "kuchaja nthawi imodzi". Malo ambiri a 150kW ali ndi zolumikizira ziwiri (CCS1, CCS2, kapena CHAdeMO). Siteshoni yapamwamba kwambiri idzakhala ndi mphamvu yogawana mphamvu. Mwachitsanzo, ngati magalimoto awiri alumikizidwa, siteshoniyo iyenera kugawa 75kW pa chilichonse, kapena kuyika galimotoyo patsogolo mwanzeru ndi mphamvu yotsika. Kumvetsetsa kuchuluka kwa mphamvu imeneyi—kaya imachitika mu 10kW increments kapena 50/50 splits yokhazikika—ndi chinthu chofunikira kwambiri pakusiyanitsa.

Kuyeza malo ndi malo ozungulira kumakhalanso ndi gawo lofunika kwambiri. Pa malo okhala mumzinda omwe malo ndi apamwamba, chipangizo chaching'ono, chonse-mu-chimodzi nthawi zambiri chimakondedwa. Komabe, pa malo amisewu, njira yogawanika (komwe kusintha kwa mphamvu kumachitika mu kabati yakutali ndipo wogwiritsa ntchito amalumikizana ndi chotulutsira chocheperako) ingakhale yoyenera kwambiri. Ogula ayeneranso kutsimikizira kutsimikizira kwa Ingress Protection (IP) ndi Impact Protection (IK). Pakugwiritsa ntchito pagulu panja, kuyerekezera kwa IP54 kapena IP55 kuphatikiza ndi kuyerekezera kwa IK10 kwa nyumba ndi sikirini nthawi zambiri kumaonedwa ngati muyezo wamakampani wokhazikika motsutsana ndi nyengo ndi kuwonongeka.

Pomaliza, mawonekedwe a ogwiritsa ntchito (UI) ndi kuphatikiza malipiro sizinganyalanyazidwe. Chaja ya 150kW ndi chida choyang'ana pagulu. Kusankha kwaukadaulo kuyenera kuphatikizapo chophimba chowoneka bwino, chowoneka bwino padzuwa, chithandizo cha zilankhulo zambiri, ndi malo olimba olipira omwe amathandizira RFID, makhadi a ngongole/debit, ndi ma wallet am'manja. M'madera ambiri, malamulo a "otseguka" tsopano alamula kuti ma charger ayenera kulandira makhadi a ngongole popanda kufunikira pulogalamu inayake kapena umembala, zomwe zimapangitsa kusankha zida zolipirira zophatikizika kukhala kofunikira kwambiri.

Mutu 3: Mphamvu ya Modularity: Kapangidwe ka Nyumba, Kukulitsa Pamodzi, ndi Kuchulukanso

M'masiku oyambirira a DC fast charging, mayunitsi ambiri ankamangidwa pogwiritsa ntchito mapangidwe a "monolithic". Ngati gawo limodzi lamkati lalephera, charger yonse imachoka pa intaneti. Masiku ano, makampaniwa asintha kupita ku modular parallel architecture, yomwe mwina ndiyo kupita patsogolo kwaukadaulo kwa ma charger a 150kW. Mu kapangidwe kameneka, kutulutsa kwa 150kW kumapangidwa ndi mulu wa ma module ang'onoang'ono, osinthika ndi kutentha - nthawi zambiri 20kW, 30kW, kapena 40kW iliyonse.

Ubwino wa modularity ndi wa magawo atatu: kudalirika, kuthekera kogwira ntchito, ndi kufalikira. Kuchokera pamalingaliro odalirika, ngati chojambulira cha 150kW chili ndi ma module asanu a 30kW ndipo module imodzi yalephera, siteshoniyo siikhala yakuda. M'malo mwake, imalowa mu "mode yowonongeka," kupitiliza kupereka mphamvu ya 120kW kwa wogwiritsa ntchito. Izi zimatsimikizira kuti dalaivala sasowa chochita, zomwe ndizofunikira kwambiri kuti makasitomala akhutire komanso mbiri ya tsamba.

Kugwira ntchito bwino kwakhala bwino kwambiri. M'malo mofuna injiniya wodziwa bwino ntchito kuti azindikire ndikukonza ma circuitry ovuta amkati pamalopo, katswiri amatha kungozindikira gawo lolakwika ndikulisintha ndi lina mumphindi zochepa. Izi zimachepetsa Mean Time to Repair (MTTR) ndikuchepetsa katundu wonyamula zida zazikulu komanso zolemera. Kwa ogwira ntchito akuluakulu, izi zikutanthauza kuti ndalama zogwirira ntchito (OPEX) zichepa kwambiri.

Pomaliza, modularity imapereka njira yotetezera mtsogolo. Wogula angayambe ndi kasinthidwe ka 150kW koma akhazikitse kabati yomwe imatha kusunga ma module okwana 200kW kapena 300kW. Pamene kufunikira kukukulirakulira ndipo mphamvu ya gridi ikulola, wogwiritsa ntchitoyo amatha kungoyika ma module ena kuti awonjezere mphamvu ya malo popanda kufunikira kusintha siteshoni yonse yeniyeni kapena kukumba ngalande zatsopano. Chitsanzo ichi cha "kulipirira pamene mukukula" ndi chokopa kwambiri kwa osunga ndalama omwe sakudziwa za kuchuluka kwa magetsi a EV omwe akugwiritsidwa ntchito nthawi yomweyo m'malo awo enieni.

Mutu 4: Mphamvu ya Module Synergy: Kukonza Bwino ndi Ma Algorithms Oyenera Kulipira

Luntha la chojambulira cha 150kW DC chofulumira silili m'zigawo zake zamagetsi zokha, komanso mu pulogalamu yapamwamba yomwe imakonza mgwirizano pakati pa ma module ake amphamvu. Mu dongosolo la modular, chowongolera chapakati chimagwira ntchito ngati "ubongo," kuyang'anira momwe magetsi amatengedwa kuchokera ku module iliyonse kuti apititse patsogolo magwiridwe antchito komanso moyo wautali. Izi zimachitika kudzera mu ma algorithms apamwamba owongolera katundu omwe amayang'anira thanzi lenileni, kutentha, ndi mbiri ya kagwiritsidwe ntchito ka module iliyonse payokha.

Kukonza bwino ntchito ndi chinthu chofunikira kwambiri pa chuma cha malo ochajira. Ma module ambiri amphamvu ali ndi kalembedwe kogwira ntchito komwe kamakhala pamwamba pa katundu winawake—nthawi zambiri pakati pa 50% ndi 80% ya mphamvu yawo yovomerezeka. Ngati chochajira cha 150kW chikupereka 30kW yokha ku galimoto yokhala ndi batire yodzaza, kuyendetsa ma module onse pa 20% ya katundu sikungakhale kogwira ntchito bwino chifukwa cha kutayika kwa switching yokhazikika komanso mphamvu yothandizira. Chowongolera chanzeru chimabisa ma module anayi ndikuyendetsa module imodzi ya 30kW pamalo ake ogwirira ntchito bwino. Ntchito ya "sleep mode" iyi imatha kusunga maola masauzande ambiri a kilowatt pa moyo wonse wa chochajira, zomwe zimakhudza mwachindunji phindu la wogwiritsa ntchito.

Kulinganiza katundu kumakhudzanso kayendetsedwe ka kutentha kwa ma module. Pa nthawi ya ma module amphamvu kwambiri, ma module amapanga kutentha kwakukulu. Algorithm yotsogola idzazungulira katundu pakati pa ma module kuti zitsimikizire kuti palibe chipangizo chimodzi chomwe chikuyenda bwino kuposa ena. Mwa kugawa "kupsinjika kwa kutentha" mofanana, dongosololi limaletsa kukalamba komwe kumachitika m'deralo ndikuwonjezera Mean Time Between Failures (MTBF) pa stack yonse yamagetsi. Kuphatikiza apo, ma algorithm awa amatha kuzindikira zizindikiro zoyambirira za kuwonongeka kwa ma module—monga mafunde amagetsi osazolowereka kapena kutentha kwambiri kwa katundu wina—ndikuwayika pachiwopsezo kuti akonze asanayambe kulephera.

Pa malo ogawa magetsi ambiri, mgwirizano umakhala wovuta kwambiri. Kabati yamagetsi yolumikizidwa pakati yomwe imatumikira ma pedestal angapo iyenera kugawa zinthu zake module motengera ma curve osiyanasiyana a state-of-charge (SoC) a magalimoto olumikizidwa. Ngati galimoto imodzi ili mu gawo lake la "bulk charge" ndipo ingalandire 150kW, pomwe ina ili mu gawo la "tapering" ikulandira 20kW yokha, makinawo ayenera kusuntha momasuka ma module kuchokera ku output imodzi kupita ku ina. Izi zimafuna ma protocol olumikizirana mwachangu (nthawi zambiri kutengera CAN bus kapena industrial Ethernet) mkati mwa charger kuti zitsimikizire kuti kusintha kwa magetsi kumachitika mu ma milliseconds popanda kusokoneza nthawi yochaja kapena kuyambitsa kutseka kwa chitetezo cha galimoto.

Chaputala 5: Kuwongolera Kutentha Kwambiri: Kuziziritsa kwa Madzi ndi Mpweya Wokakamizidwa kwa Okonzanso Mphamvu Zapamwamba

Pamene ma DC fast charger akukwera kufika pa 150kW ndi kupitirira apo, kasamalidwe ka kutentha kamakhala vuto lalikulu la uinjiniya. Kusintha AC yamagetsi amphamvu kuchokera ku gridi kukhala DC ya batri sikugwira ntchito bwino 100%; kutayika kwa mphamvu pafupifupi 4% mpaka 7% kumawonekera ngati kutentha. Mu dongosolo la 150kW, izi zikutanthauza kuyendetsa mpaka 10kW ya kutentha komwe kumataya—kofanana ndi ma heater akuluakulu angapo omwe akuyenda mkati mwa bokosi lachitsulo lotsekedwa. Momwe kutentha kumeneku kumagwiritsidwira ntchito kumatsimikizira mwachindunji kudalirika kwa charger, kuchuluka kwa phokoso, ndi zofunikira pakukonza.

Kuziziritsa mpweya mokakamiza ndiyo njira yachikhalidwe komanso yodziwika bwino ya mayunitsi a 150kW. Imagwiritsa ntchito mafani a mafakitale amphamvu kwambiri kuti akoke mpweya wozungulira kudzera m'magawo amagetsi ndi m'malo otenthetsera. Ngakhale kuti ndi yotsika mtengo komanso yosavuta kusamalira, kuziziritsa mpweya kuli ndi zovuta zingapo. Choyamba, kumayambitsa zodetsa zachilengedwe—fumbi, chinyezi, ndi mpweya wamchere—m'magetsi amkati, zomwe zimafuna zosefera zapamwamba komanso zosinthidwa pafupipafupi. Chachiwiri, mphamvu ikakwera kwambiri, mafani amatha kukhala ndi phokoso kwambiri, zomwe zingakhale vuto m'malo okhala anthu kapena m'malo ogulitsira apamwamba. Pofuna kuchepetsa izi, opanga ena amagwiritsa ntchito mafani a "variable speed drive" omwe amangowonjezeka pokhapokha ngati pakufunika kutero, koma choletsa chachikulu chimakhalabe.

Kuziziritsa madzi ndi "muyezo wabwino kwambiri" wa zamagetsi amphamvu kwambiri, ngakhale kuti nthawi zambiri zimapezeka mu ma charger a 350kW+ ultra-fast. Komabe, mapangidwe ena apamwamba a 150kW akuyamba kugwiritsa ntchito ma modules ozizira madzi kapena ukadaulo wa cold-plate. Mu machitidwe awa, coolant (nthawi zambiri chisakanizo cha madzi-glycol) chimayendetsedwa kudzera mu ma modules amphamvu, kunyamula kutentha kupita ku radiator yakutali. Izi zimathandiza kuti pakhale malo otsekedwa kwathunthu, kuteteza zamagetsi ku nyengo komanso kuchepetsa phokoso kwambiri. Kwa ogula omwe ali m'malo otentha kwambiri—kaya m'zipululu zotentha kwambiri kapena m'mphepete mwa nyanja ndi mpweya wamchere—mtengo wapamwamba wa makina oziziritsa madzi kapena otsekedwa mpweya nthawi zambiri umakhala wolondola chifukwa chochepetsa kukonza komanso nthawi yayitali ya zida.

Chinthu china chofunika kwambiri chomwe chiyenera kuganiziridwa pa kutentha kwa 150kW ndi chingwe chochajira chokha. Zingwe zokhazikika zosazizira nthawi zambiri zimakhala ndi ma Amps 200 chifukwa cha kutentha komwe kumawonjezeka m'ma conductors amkuwa. Kuti galimoto ya 400V ipereke 150kW, makinawo amafunika kukankhira ma Amps 375. Izi zimafuna chingwe chokhuthala kwambiri, cholemera, komanso chovuta kuchigwira, kapena kugwiritsa ntchito chingwe choziziritsidwa ndi madzi. Chingwe choziziritsidwa chimagwiritsa ntchito madzi ozungulira kuti chigwirizire ndi waya zizizire, zomwe zimapangitsa kuti chikhale chopyapyala komanso chokongola chomwe chingathe kugwira 400A kapena 500A. Posankha chochajira cha 150kW, ogula ayenera kuwona ngati chipangizocho chili ndi zingwe zoziziritsidwa kapena ngati chikugwiritsa ntchito njira "zowonjezera" zomwe zimalola mphamvu yamagetsi yapamwamba kwa nthawi yochepa kutsatiridwa ndi kutentha kotsika.

Mutu 6: Kulumikizana kwa Gridi ndi Ubwino wa Mphamvu: Ma Harmoniki, Ma Transformers, ndi Kusungirako Mphamvu Zam'deralo

Kukhazikitsa chojambulira chachangu cha 150kW DC ndi ntchito yaukadaulo wa zomangamanga komanso yamagetsi. Chida chimodzi cha 150kW chimagwiritsa ntchito mphamvu zambiri kuchokera ku gridi yogawa yakumaloko—nthawi zambiri kuposa nyumba yaying'ono yaofesi kapena nyumba khumi ndi ziwiri pamodzi. Izi zimafuna mgwirizano wosamala ndi kampani yamagetsi yakomweko kuti zitsimikizire kuti gridiyo ikhoza kuthana ndi zinthu zazikulu mwadzidzidzi zokhudzana ndi kuchaja mwachangu.

Ubwino wa magetsi ndi nkhani yaikulu yaukadaulo pa zamagetsi. Ma charger othamanga ndi zinthu zosagwiritsa ntchito mzere zomwe zimagwiritsa ntchito kusintha kwa ma frequency ambiri, zomwe zimatha kuyambitsa "harmonics" mu gridi. Ma harmonics awa amatha kuyambitsa kutentha kwambiri mu ma transformer amagetsi ndi kusokoneza zida zina zomvera zomwe zili mu circuit yomweyo. Ma charger apamwamba a 150kW ayenera kukhala ndi Active Power Factor Correction (PFC) ndi kusefa kwapamwamba kuti Total Harmonic Distortion (THD) ikhale pansi pa 5%, zomwe zikugwirizana ndi miyezo monga IEEE 519. Ogula ayenera kufunafuna ziphaso zomwe zimatsimikizira kuti charger "sidzadetsa" magetsi am'deralo, chifukwa magetsi ena amatha kukana kulumikizana ndi mayunitsi omwe alibe kusefa koyenera.

Kapangidwe ka zinthu zakuthupi nthawi zambiri kamafuna transformer yapadera kuti ichepetse mphamvu yapakati (monga 11kV kapena 33kV) kupita ku 480V kapena 400V AC yomwe imafunika ndi chojambulira. Transformer iyi iyenera kukhala ya kukula osati kokha kwa 150kW, komanso kuti ikule bwino komanso kuti ikule mtsogolo. Kuphatikiza apo, mtunda pakati pa transformer ndi chojambulira ndi wofunikira kwambiri; kuyenda kwa nthawi yayitali kwa chingwe chamagetsi ochepa kungayambitse kuchepa kwakukulu kwa magetsi ndi kutayika kwa mphamvu, kuchepetsa mphamvu yogwira ntchito yomwe imaperekedwa ku galimoto ndikuwonjezera bilu yamagetsi ya wogwiritsa ntchito.

M'madera omwe ali ndi ma gridi ofooka kapena "zolipiritsa zofunikira" zambiri (zilango zogwiritsa ntchito mphamvu zambiri), malo osungira mphamvu m'deralo akukhala njira yotchuka. Mwa kuphatikiza chojambulira cha 150kW ndi Battery Energy Storage System (BESS), ogwiritsa ntchito amatha "kuletsa" gridi. BESS imachaja pang'onopang'ono kuchokera ku gridi nthawi yomwe si nthawi yotanganidwa kenako imatuluka mwachangu kuti ithandizire kufunikira kwa 150kW galimoto ikalowa. Njira iyi ya "kumeta gridi" ikhoza kuchepetsa kwambiri ndalama zogwirira ntchito ndikulola kuti kuyatsa mwachangu m'malo omwe kukweza gridi mwachindunji kungakhale kokwera mtengo kwambiri. Kuphatikiza izi mu kusankha kwaukadaulo kumafuna chojambulira chokhala ndi kapangidwe ka DC-link komwe kumatha kulandira mosavuta zolowera kuchokera ku gridi komanso batri yosasuntha.

Mutu 7: Chitetezo Choyamba: Njira Zotetezera Zipangizo ndi Mapulogalamu a Zigawo Zambiri

Chitetezo pakuchaja kwa DC kwamphamvu kwambiri n'chofunika kwambiri, chifukwa chochaja cha 150kW chimagwira ntchito pamagetsi ndi mafunde omwe angakhale oopsa ngati sichiyendetsedwa bwino. Siteshoni ya 150kW yaukadaulo imakhala ndi zigawo zingapo zotetezera, kuyambira zolumikizira zakuthupi mpaka pulogalamu yoyang'anira yochokera ku mtambo. Njirazi zapangidwa kuti ziteteze wogwiritsa ntchito, galimoto, gridi, ndi zida zochaja zokha ku zolakwika.

Gawo loyamba ndi chitetezo cha hardware. Izi zikuphatikizapo Residual Current Devices (RCDs) za Mtundu B, zomwe zimatha kuzindikira mafunde a AC ndi DC. Ngati vuto la nthaka lachitika, zipangizozi zimatha kugwedezeka mu ma milliseconds, zomwe zimachotsa charger ku magetsi. Kuphatikiza apo, charger iyenera kukhala ndi zida zoteteza ma surge (SPDs) kuti iteteze ku mphezi kapena ma grid transients. Mkati mwa kabati, gawo lililonse lamagetsi liyenera kukhala ndi fuse kapena circuit breaker yake kuti lisagwere mu ngozi yayikulu ya moto. Chingwe chochaja chokha chimakhala ndi masensa otenthetsa mu connector head; ngati ma pin atentha kwambiri chifukwa cha kulumikizana koyipa kapena kutentha kwambiri, makinawo adzachepetsa mphamvu yamagetsi yokha kapena kuimitsa gawolo.

Gawo lachiwiri ndi chitetezo chogwirizana ndi kulumikizana. Kuchaja kwa DC kwamakono kumadalira njira za ISO 15118 kapena DIN 70121 zogwirirana chanza pakati pa chochaja ndi galimoto. Mphamvu ya watt imodzi isanaperekedwe, makina awiriwa amachita mayeso odziyesa okha. Galimotoyo imalankhula za thanzi la batri lake, mphamvu yamagetsi yovomerezeka, komanso malire a mphamvu yamagetsi. Chochajacho chimatsimikizira momwe chilili mkati mwake komanso kukana kwake kutenthetsa. Magulu onse awiri akatsimikizira kuti "ndi otetezeka kupitiliza" ndiye kuti cholumikizira chimatseka. Pa nthawi yonse yochaja, kugunda kwa mtima kumeneku kumasungidwa; ngati kulumikizana kwatayika ngakhale kwa ma millisecond angapo, gawolo limadulidwa nthawi yomweyo kuti likhale lotetezeka.

Gawo lachitatu ndi kuyang'anira kutchinjiriza. Ma DC fast charger amagwira ntchito mu "IT grid" (yokhayokha), zomwe zikutanthauza kuti mizere ya DC yabwino kapena yoyipa siilumikizidwa pansi. Chipangizo Chowunikira Kutchinjiriza (IMD) nthawi zonse chimayesa kukana pakati pa basi ya DC ndi chassis. Ngati kulowa kwa chinyezi kapena kuwonongeka kwa chingwe kumapangitsa kuti kutchinjiriza kuchepe pansi pa malire enaake (nthawi zambiri kumayesedwa mu ma kilo-ohms), IMD imayambitsa kuzimitsa nthawi yomweyo. Izi ndizofunikira kwambiri popewa ngozi za "touch voltage" komwe wogwiritsa ntchito angalandire kugwedezeka kuchokera ku chivundikiro chachitsulo cha charger.

Pomaliza, chitetezo chofotokozedwa ndi mapulogalamu chimapereka chitetezo chowonjezera. Chowongolera chapakati chimayang'anira deta yonse ya sensa—kutentha, magetsi, mphamvu, ndi liwiro la fan—motsutsana ndi ma envelopu achitetezo omwe adakhazikitsidwa kale. Ngati gawo lililonse lipita kunja kwa malo otetezeka, pulogalamuyo ikhoza kuyambitsa kutseka kolamulidwa. Mwachitsanzo, ngati magetsi a gridi atsika kwambiri (brownout), pulogalamuyo idzayimitsa bwino gawoli kuti isawononge magawo olowera a ma module amagetsi. Makina apamwamba alinso ndi "arc flash detection," yomwe imagwiritsa ntchito masensa owunikira kuti azindikire ma arc amagetsi amkati ndikugwetsa choswera chachikulu moto usanayambe.

Mutu 8: Dongosolo la Mapulogalamu: OCPP 1.6J/2.0.1 Kuphatikiza, Kulipira, ndi Kuyang'anira Patali

Chaja yofulumira ya 150kW DC si chipangizo chodziyimira pachokha; ndi chipangizo cholumikizidwa ndi netiweki chomwe chiyenera kulumikizidwa mu pulogalamu yovuta. Muyezo wamakampani pakulankhulana uku ndi Open Charge Point Protocol (OCPP). Mukasankha chaja, kuonetsetsa kuti ikutsatira kwathunthu OCPP 1.6J (JSON) ndiye chofunikira kwambiri, pomwe kuthandizira muyezo watsopano wa OCPP 2.0.1 kumalimbikitsidwa kwambiri kuti zitsimikizidwe mtsogolo.

OCPP imalola chojambulira ("malo ojambulira") kuti chilumikizane ndi seva yapakati ("Charging Station Management System" kapena CSMS). Kuphatikiza kumeneku kumalola zinthu zofunika monga kuyang'anira patali, zosintha za firmware, ndi kubweza. Kwa wogula, kuphatikiza kwa OCPP kumatanthauza "palibe wogulitsa wotseka." Ngati simukukhutira ndi wopereka mapulogalamu anu, mutha kusintha kupita ku ina popanda kufunikira kusintha zida zakuthupi. Kusinthasintha kumeneku ndikofunikira kwambiri kuti ntchito ikhale yolimba kwa nthawi yayitali. Chojambulira "chotseguka" chenicheni chidzakhala ndi chitsimikizo cha kukhazikitsa kwa OCPP ndi Open Charge Alliance (OCA), kuonetsetsa kuti imatha kulankhulana bwino ndi aliyense wotsatira malamulo.

Kulipira ndi kupeza ndalama kumachitika kudzera mu pulogalamu iyi. Chojambulirachi chimatumiza deta yoyesedwa ku CSMS, yomwe kenako imakonza zolipira kutengera mphamvu zomwe zimagwiritsidwa ntchito (kWh), nthawi yomwe imagwiritsidwa ntchito (mphindi), kapena kuphatikiza zonse ziwiri. M'misika yambiri, mitengo yosinthasintha ikukhala njira yofunika kwambiri—kuchaja kwambiri nthawi yomwe anthu akufuna kwambiri komanso kupereka kuchotsera pamene kupanga mphamvu zongowonjezwdwa kuli kokwera. Ma charger apamwamba a 150kW amathandiziranso "Plug & Charge" (ISO 15118-2), komwe galimotoyo imadzizindikiritsa yokha ku chojambuliracho, kuchotsa kufunikira kwa makadi a RFID kapena mapulogalamu am'manja. Izi zimapereka chidziwitso chofanana ndi "Tesla" kwa wogwiritsa ntchito ndikuwonjezera kuchuluka kwa siteshoni.

Kuyang'anira ndi kuzindikira kutali ndi komwe mapulogalamu amapereka phindu lalikulu. Siteshoni ya 150kW ndi chuma chamtengo wapatali, ndipo nthawi yopuma imatanthawuza mwachindunji kutayika kwa ndalama. CSMS yolimba imatha kupereka machenjezo nthawi yeniyeni ya zolakwika zilizonse, zomwe zimathandiza ogwira ntchito kukonza mavuto—monga pulogalamu yopachikidwa kapena chopunthira—kutali popanda kutumiza katswiri patsamba lino. Kuphatikiza apo, zosintha za firmware yakutali zimatsimikizira kuti chochapiracho chingakhale chogwirizana ndi mitundu yatsopano ya EV pamene ikutulutsidwa.

Mutu 9: Kusanthula Zachuma: Capex, Opex, ndi 150kW Revenue Model (ROI)

Kuyika ndalama mu charger ya 150kW DC kumafuna kumvetsetsa bwino momwe ndalama zilili. Ndalama Zonse Zogulira (TCO) zimagawidwa m'magulu a Capital Expenditure (CAPEX) ndi Operational Expenditure (OPEX), zomwe ziyenera kukonzedwa mosamala kuti zitsimikizire kuti ndalamazo zikubweza bwino (ROI).

CAPEX imaphatikizapo mtengo wogulira chojambuliracho, chomwe pa chipangizo chapamwamba cha 150kW chingakhale kuyambira $30,000 mpaka $60,000 kutengera mawonekedwe ndi mtundu wa zomangamanga. Komabe, mtengo wa zida nthawi zambiri umakhala 40% mpaka 50% yokha ya mtengo wonse woyikira. Ntchito za boma—kukonza ngalande, ma konkriti, ndi ma bollard oteteza—zingakhale zofunika kwambiri, makamaka m'mizinda. Kukonzanso magetsi, kuphatikizapo transformer yatsopano ndi switchgear yokwera mphamvu, kungawonjezere ndalama zambiri ku bilu. Ndalama zololeza ndi zolumikizira kuchokera ku kampani yothandiza ziyeneranso kuganiziridwa. Kwa ogula ambiri, ndalama zothandizira boma ndi zolimbikitsira misonkho ndizofunikira kwambiri pochepetsa ndalama zoyambira izi, nthawi zambiri zimakhala 50% mpaka 80% ya CAPEX m'madera omwe ali ndi zolinga zamagetsi zolimba.

OPEX ndi ndalama zomwe zimafunika kuti siteshoni igwire ntchito. Gawo lalikulu kwambiri nthawi zambiri ndi mtengo wamagetsi, womwe sumangophatikizapo mphamvu zomwe zimagwiritsidwa ntchito komanso "ndalama zomwe zimafunika." Izi ndi ndalama zomwe zimaperekedwa pamwezi kutengera mphamvu zomwe zimakokedwa kwambiri (mu kW) zomwe zalembedwa pamalopo. Gawo limodzi la 150kW lingayambitse ndalama zambiri zomwe zimafunika zomwe zimachotsa phindu kuchokera ku magawo ang'onoang'ono ambiri. Kusamalira izi kumafuna pulogalamu yochapira mwanzeru kapena malo osungira batri monga momwe tafotokozera mu Mutu 6. Zinthu zina za OPEX zikuphatikizapo kulembetsa kwa mwezi uliwonse kwa CSMS, kulumikizana kwa mafoni a chaja, ndi maulendo okonza pachaka. Lamulo labwino ndikukhala ndi bajeti ya 3% mpaka 5% ya ndalama zomwe zimagwiritsidwa ntchito pokonza ndi kukonza pachaka.

Njira yopezera ndalama pa siteshoni ya 150kW ikusintha kuposa kugulitsa mphamvu kokha. Ngakhale kuti "malire pa kWh" ndiye choyambitsa chachikulu, ogwira ntchito opambana akusinthasintha njira zawo zopezera ndalama. Ena amapereka mitengo ya "liwiro lapamwamba", komwe makasitomala amalipira mtengo wapamwamba kuti apeze chojambulira cha 150kW poyerekeza ndi mayunitsi ocheperako. Ena amagwiritsa ntchito siteshoni yochapira ngati "chitsogozo chotayika" kuti ayendetse magalimoto oyenda pansi kupita kumalo ogulitsira - kuwonjezera "nthawi yokhala" ndi ndalama zina m'ma cafe kapena m'masitolo. Kuphatikiza apo, pamene ukadaulo wa V2G (Galimoto-kupita-ku-Grid) ukukulirakulira, malo ochapira a 150kW amatha kupeza ndalama popereka malamulo oyendetsera pafupipafupi ndi ntchito zina zothandizira pa gridi. Kuti awerengere ROI, ogwira ntchito ayenera kuwonetsa kuchuluka kwa magwiritsidwe ntchito - kuchuluka kwa tsiku lomwe chojapira chikugwiritsidwa ntchito. Chojapira cha 150kW nthawi zambiri chimafunikira kuchuluka kwa magwiritsidwe ntchito kwa 15% mpaka 20% kuti chiwonjezeke ngakhale mkati mwa zaka 3 mpaka 5, poganiza kuti pali kusiyana koyenera pakati pa mitengo yogula ndi kugulitsa magetsi.

Mutu 10: Njira Zokhazikitsira ndi Kugwira Ntchito ndi Kusamalira Kwa Nthawi Yaitali (O&M)

Kusintha kuchoka pa katundu wogulidwa kupita ku malo ochapira mwachangu a 150kW DC ndi ulendo wovuta womwe umafuna kukonzekera mosamala komanso kudzipereka kwa nthawi yayitali pakukonza. Kukhazikitsa si chochitika cha "plug-and-play"; ndi pulojekiti yaukadaulo yambiri. Gawo losankha malo liyenera kuganizira momwe zinthu zingakhalire—kuonetsetsa kuti magalimoto a EV ndi ma vani atali-wheelbase amatha kulowa mosavuta m'malo ochapira popanda kuletsa magalimoto. Kuyang'ana kwa charger kuyenera kuchepetsa kupsinjika kwa chingwe; chipangizo chosayikidwa bwino chimapangitsa kuti zingwe zikokedwe kudutsa msewu, zomwe zimapangitsa kuti zinthu zoteteza kutentha ndi zolumikizira ziwonongeke msanga.

Zinthu zofunika kuziganizira pa zaukadaulo wa zomangamanga nazonso n'zofunika kwambiri. Maziko a konkriti a chipangizo cha 150kW ayenera kupangidwa kuti athandize kulemera kwa kabati (komwe kungapitirire 500kg pa mayunitsi a modular) ndikupewa mphepo m'malo owonekera. Mayendedwe a ngalande zapansi panthaka ayenera kukhala a kukula kwa zingwe zamkuwa kapena aluminiyamu zokhala ndi mphamvu zambiri, mosamala kwambiri kuti ma radii opindika asawonongeke ndi kutentha. M'nyengo yozizira, kutsatira kutentha kwa ngalande kapena maziko kungakhale kofunikira kuti chisanu chisawononge maulumikizidwe amagetsi. Kuunikira ndi chinthu china chofunikira koma nthawi zambiri sichimaganiziridwa; siteshoni yowunikira bwino imamva yotetezeka kwa ogwiritsa ntchito usiku ndipo imathandiza makamera ophatikizidwa (ngati alipo) kujambula zithunzi zomveka bwino kuti atetezeke komanso kupewa kuwonongeka.

Siteshoni ikangoyatsidwa, cholinga chake chimasamutsidwa ku Ntchito ndi Kukonza (O&M). Njira yoyendetsera ntchito ya O&M ndiyo imasiyanitsa malo opindulitsa ndi udindo. Timagawa kukonza m'magulu atatu: kupewa, kukonza, ndi kuneneratu. Kukonza koteteza kumaphatikizapo kupita kumalo komwe kukuchitika—nthawi zambiri miyezi isanu ndi umodzi iliyonse—kuti tichite ntchito monga kuyeretsa kapena kusintha zosefera za mpweya, kuyang'ana mphamvu ya magetsi (zomwe zimatha kumasuka pakapita nthawi chifukwa cha kutentha), ndikuyang'ana zingwe zochapira kuti zione ngati pali ma nicks kapena ma cut. Timalimbikitsanso "kuyeretsa kwambiri" nthawi ndi nthawi m'chipinda chotchingira kuti tichotse fumbi ndi zodetsa zomwe zingalepheretse kutentha kutayika.

Kukonza zinthu moyenera ndi njira yothetsera vuto lenileni. Kukhala ndi Pangano la Utumiki (SLA) ndi kontrakitala wamagetsi wakomweko ndikofunikira kuti zinthu zofunika kwambiri zithetsedwe mkati mwa maola 24 mpaka 48. Pa ma charger a modular 150kW, kukonza zinthu moyenera nthawi zambiri kumaphatikizapo kungosinthana ndi module yamagetsi, koma kungaphatikizeponso kukonza chinsalu chosweka kapena kusintha chogwirira chochapira chomwe chawonongeka. Kukonza zinthu moyenera ndi njira yapamwamba kwambiri, pogwiritsa ntchito deta yopangidwa ndi charger kuti muyembekezere kulephera. Poyang'anira kutentha kwamkati kwa module yamagetsi poyerekeza ndi katundu wake, pulogalamuyo imatha kulosera kulephera kwa fan kapena capacitor yotsika. Izi zimathandiza kusintha nthawi yoyendera, kupewa kuzimitsa kosayembekezereka komanso kutayika kwa ndalama komanso kudalira makasitomala.

Mutu 11: Kutsatira Malamulo, Miyezo, ndi Kutsimikizira Zamtsogolo kwa Kuchaja Megawatt

Kuyendera miyezo yapadziko lonse lapansi ndi malamulo am'deralo ndi chimodzi mwa zinthu zovuta kwambiri posankha chojambulira chachangu cha 150kW DC. Kutsatira malamulo sikuti ndi chitetezo chokha; koma ndi nkhani yokhudzana ndi mgwirizano ndi chitetezo chalamulo.
