Kusiyana Koyamba

Ngati muli ndi galimoto yamagetsi, posachedwa kapena mtsogolo, mudzakumana ndi zambiri zokhudza kuyatsa kwa AC vs DC. Mwina mukudziwa kale mawu ofupikitsa awa koma simukudziwa momwe amagwirizanirana ndi EV yanu.

Nkhaniyi ikuthandizani kumvetsetsa kusiyana pakati pa ma DC charger ndi ma AC charger. Mukawerenga, mudzadziwanso njira yochajira mwachangu komanso yomwe ili yabwino kwa galimoto yanu.

Tiyeni tiyambe!

Kusiyana #1: Malo Osinthira Mphamvu

Pali mitundu iwiri ya ma transmitter amagetsi omwe angagwiritsidwe ntchito pochajira magalimoto amagetsi. Amatchedwa Alternating Current (AC) ndi Direct Current (DC) power.

Mphamvu yochokera ku gridi yamagetsi nthawi zonse imakhala Alternating Current (AC). Komabe, batire ya galimoto yamagetsi imatha kulandira Direct Current (DC) yokha. Kusiyana kwakukulu pakati pa AC ndi DC charging, komabe, ndimalo omwe mphamvu ya AC imasinthidwaIkhoza kusinthidwa kunja kapena mkati mwa galimoto.

Ma DC charger nthawi zambiri amakhala akuluakulu chifukwa chosinthira chimakhala mkati mwa malo ochajira. Izi zikutanthauza kuti chimakhala chachangu kuposa ma AC charger pankhani yochajira batri.

Mosiyana ndi zimenezi, ngati mugwiritsa ntchito AC charging, njira yosinthira imayamba mkati mwa galimoto yokha. Magalimoto amagetsi ali ndi AC-DC converter yomangidwa mkati yotchedwa "onboard charger" yomwe imasintha mphamvu ya AC kukhala mphamvu ya DC. Pambuyo posintha mphamvu, batire ya galimotoyo imachajidwa.

Kusiyana kwachiwiri: Kuchaja Kunyumba ndi Ma AC Charger

Mwachidule, mutha kukhazikitsa chojambulira cha DC kunyumba. Komabe, sizikumveka bwino.

Ma charger a DC ndi okwera mtengo kwambiri kuposa ma charger a AC.

Zimatenga malo ambiri ndipo zimafuna zida zosinthira zovuta kwambiri pazinthu monga kuziziritsa kwamphamvu.

Kulumikiza magetsi ambiri ku gridi yamagetsi ndikofunikira.

Kuphatikiza apo, DC charging sikulimbikitsidwa kuti mugwiritse ntchito nthawi zonse - tidzakambirana izi mtsogolo. Popeza zonsezi ndi zoona, mutha kunena kuti AC charger ndi chisankho chabwino kwambiri chokhazikitsa nyumba. Malo ochapira a DC amapezeka kwambiri m'misewu ikuluikulu.

Kusiyana #3: Kuchaja kwa Foni ndi AC

Ma AC charger okha ndi omwe angakhale osavuta kugwiritsa ntchito. Ndipo pali zifukwa ziwiri zazikulu zomwe zimachititsa izi:

Choyamba, chojambulira cha DC chili ndi chosinthira champhamvu kwambiri. Chifukwa chake, kunyamula nacho paulendo n'kosatheka. Chifukwa chake, pali mitundu yosasinthika ya chojambulira chotere.

Kachiwiri, chojambulira choterechi chimafuna ma input a 480+ volts. Chifukwa chake, ngakhale chitakhala choyenda, simungapeze gwero lamagetsi loyenera m'malo ambiri. Kuphatikiza apo, malo ambiri ochapira magetsi a EV amapereka charging ya AC, pomwe ma DC charger amakhala m'mbali mwa misewu ikuluikulu.

Kusiyana #4: Kuchaja kwa DC Kumathamanga Kuposa Kuchaja kwa AC

Kusiyana kwina kofunikira pakati pa AC ndi DC charging ndi liwiro. Monga mukudziwa kale, DC charger ili ndi converter mkati mwake. Izi zikutanthauza kuti mphamvu yochokera ku DC charging station imadutsa charger ya galimotoyo ndikulowa mwachindunji mu batire. Njirayi imasunga nthawi chifukwa chosinthira mkati mwa EV charger ndi chogwira ntchito bwino kwambiri kuposa chomwe chili mkati mwa galimotoyo. Chifukwa chake, kuchaja ndi direct current kumatha kukhala kofulumira kakhumi kapena kuposerapo kuposa kuchaja ndi alternating current.

Kusiyana #5: Mphamvu ya AC vs DC - Mzere Wosiyana Wochaja

Kusiyana kwina kwakukulu pakati pa AC ndi DC charging ndi mawonekedwe a charging curve. Pankhani ya AC charging, mphamvu yoperekedwa ku EV imangokhala yosalala. Chifukwa cha izi ndi kukula kochepa kwa charger yomwe ili mkati mwake, komanso mphamvu yake yochepa.

Pakadali pano, kuyitanitsa kwa DC kumapanga curve yotsika ya chaji, chifukwa poyamba batire ya EV imalandira mphamvu yothamanga kwambiri, koma pang'onopang'ono imafuna zochepa ikafika pamlingo wapamwamba kwambiri.

Kusiyana #6: Kuchaja ndi Thanzi la Batri

Ngati muyenera kusankha ngati mungogwiritsa ntchito mphindi 30 kapena maola 5 kutchaja galimoto yanu, chisankho chanu n'chodziwikiratu. Koma sizophweka, ngakhale simusamala za kusiyana kwa mitengo pakati pa kuchaja mwachangu (DC) ndi kuchaja wamba (AC).

Nkhani ndi yakuti, ngati chojambulira cha DC chikugwiritsidwa ntchito nthawi zonse, mphamvu ya batri komanso kulimba kwake zitha kusokonekera. Ndipo iyi si nthano yowopsa chabe m'dziko la e-mobility, koma chenjezo lenileni lomwe opanga magalimoto ena amaliyika m'mabuku awo.

Magalimoto ambiri atsopano amagetsi amathandizira kuyitanitsa mphamvu yamagetsi yokhazikika pa 100 kW kapena kuposerapo, koma kuyitanitsa pa liwiro limeneli kumapanga kutentha kwambiri ndipo kumawonjezera zomwe zimatchedwa ripple effect - mphamvu ya AC imasinthasintha kwambiri pamagetsi a DC.

Kampani ya telematics ikuyerekeza momwe ma charger a AC ndi DC amakhudzira. Pambuyo pa miyezi 48 yofufuza momwe mabatire amagetsi amagwirira ntchito, idapeza kuti magalimoto omwe amagwiritsa ntchito ma charger othamanga kwambiri nthawi zoposa katatu pamwezi m'nyengo yotentha kapena nyengo yotentha anali ndi kuwonongeka kwa mabatire ndi 10% kuposa omwe sanagwiritse ntchito ma charger othamanga a DC.

Kusiyana #7: Kuchaja kwa AC ndikotsika mtengo kuposa kuchaja kwa DC

Kusiyana kwakukulu pakati pa kuyatsa kwa AC ndi DC ndi mtengo wake — ma charger a AC ndi otsika mtengo kwambiri kugwiritsa ntchito kuposa a DC. Nkhani yake ndi yakuti ma charger a DC ndi okwera mtengo kwambiri. Kuphatikiza apo, ndalama zoyikira ndi kulumikiza gridi ndizokwera.

Mukachaja galimoto yanu pa DC power point, mutha kusunga nthawi yambiri. Chifukwa chake ndikwabwino kwambiri pazochitika zomwe mukufulumira. Pazochitika zotere, ndikwanzeru kulipira mtengo wokwera kuti muwonjezere liwiro la chaji. Pakadali pano, kuchaja ndi AC power ndikotsika mtengo koma kumatenga nthawi yayitali. Mwachitsanzo, ngati mutha kuchaja EV yanu pafupi ndi ofesi mukugwira ntchito, palibe chifukwa cholipira mopitirira muyeso kuti mudzaze mwachangu kwambiri.

Ponena za mtengo, kuyitanitsa nyumba ndiyo njira yotsika mtengo kwambiri. Chifukwa chake kugula malo anu oyitanitsa ndi njira yomwe ingakuyenerereni kwambiri.

Pomaliza, mitundu yonse iwiri ya kuchaja ili ndi ubwino wake. Kuchaja kwa AC ndikwabwino kwambiri pa batire ya galimoto yanu, pomwe mtundu wa DC ungagwiritsidwe ntchito pazochitika zomwe muyenera kuchaja batire yanu nthawi yomweyo. Kuchokera pazomwe takumana nazo, palibe chifukwa chenicheni chochaja mwachangu kwambiri, chifukwa eni ake ambiri a EV amachaja mabatire awo usiku kapena akaimika pafupi ndi ofesi. Bokosi la AC monga go-e Charger Gemini flex kapena go-e Charger Gemini, lingakhale yankho labwino kwambiri. Mutha kuyiyika kunyumba kapena m'nyumba ya kampani yanu, zomwe zimapangitsa kuti kuchaja kwa EV kwaulere kukhale kotheka kwa antchito anu.

Apa, mupeza zonse zofunika zokhudza kuyatsa kwa AC vs DC ndi kusiyana pakati pa izi:
