Intangiriro: Imbibi Zihuza Ikoranabuhanga mu Kubika Ingufu mu Bikoresho by'Ikoranabuhanga (E-Mobility) n'Ingufu

Impinduka ku isi yose ku binyabiziga bikoresha amashanyarazi (EVs) ntabwo ikiri iy'ejo hazaza; ni ukuri kw'ubu kurimo kugenda ku muvuduko udasanzwe. Uko ibihugu biharanira kugera ku ntego za zeru, amashanyarazi mu rwego rw'ubwikorezi yabaye inkingi y'ingenzi mu ngamba zo gukuraho karubone. Ariko, uko ikoreshwa rya EVs zikoresha abagenzi n'iz'ubucuruzi ryihuta, imbogamizi z'imiyoboro y'amashanyarazi isanzweho—inyinshi muri zo zakozwe mu myaka yashize kugira ngo zikoreshwe mu buryo buhamye kandi buhoraho—zirimo kugaragara cyane. Imbogamizi nyamukuru ni ugushaka sitasiyo zikoresha ingufu nyinshi kandi zihuta cyane (UFC) zishobora gutanga ingufu zingana na 150 kW kugeza kuri 350 kW cyangwa zirenga kuri buri modoka.

Iyo charger nyinshi nk'izo zikora icyarimwe, zikora amashanyarazi menshi kandi ahindagurika. Ku kigo cy’ubucuruzi, ikigo kimwe cy’amashanyarazi cyihuta cyane cya bay 10 gishobora kwerekana umutwaro munini uhwanye n’inzu nto cyangwa uruganda ruciriritse, nyamara uyu mutwaro uragaragara kandi ukabura mu minota mike. Iyi mitwaro "ifite imigozi" ishobora kwangiza transformateur zo mu gace, igatera amashanyarazi gucika, kandi igatera ikiguzi kinini cyane ku bakoresha sitasiyo. Byongeye kandi, igisubizo gakondo - kuvugurura ibikorwa remezo by’amashanyarazi - akenshi gihenze cyane kandi gitinda, aho igihe cyo gukoresha sitasiyo nshya zifite amashanyarazi menshi kigera mu myaka myinshi.

Sisitemu zo kubika ingufu za batiri (BESS) zabaye igisubizo cy’ukuri kuri izi mbogamizi. Mu gukuramo ingufu za grid uhereye ku musaruro wa charger, ibikorwa remezo bya EV charger bya BESS (BESS+EVSE) bitanga inzira yo gukoresha ingufu byihuse, byoroshye kandi byoroshye grid. Ubu buryo buhuriweho bwemerera "gukata shearing peak," aho bateri itanga ingufu nyinshi mu gihe cyo gusharija, kandi igatanga shearing grid ku gipimo gihamye kandi gishoboka iyo charger zidakora.

Muri iyi nyandiko yuzuye ya tekiniki, tuzasuzuma ubwiyongere bwa sisitemu za BESS + EVSE mu magambo arenga 6000 y'isesengura rya tekiniki. Tuzarenga inyungu zo ku rwego rwo hejuru kugira ngo dusesengure imiterere yihariye y'amashanyarazi akoreshwa mu ikoranabuhanga, uburyo bugoye bwo kugenzura ibikoresho bihindura imiterere y'imashini enye, uburyo bw'imibare bugenga ubuzima bw'ibateri, na moteri z'ubukungu zikoresha ubuhanga bwa AI zituma izi sisitemu zidashoboka gusa mu rwego rwa tekiniki, ahubwo zigatanga inyungu nyinshi.

Igice cya 1: Imiterere yimbitse ya sisitemu za BESS + EVSE

Gushyira BESS muri sitasiyo zo gushyushya amashanyarazi bisaba kongera gutekereza ku buryo bw'ibanze ku bijyanye n'imiterere y'ingufu. Ntitugomba gusuzuma gusa uburyo ingufu zibikwa, ahubwo no kureba uburyo zigendanwa nta gihombo kinini kandi zigenzurwa cyane. Muri iki gice, turagereranya uburyo bubiri bw'ibanze bwo guhuza: sisitemu zihujwe na AC na sisitemu zihujwe na DC.

1.1 Ubwubatsi bushingiye kuri AC: Umurage n'Ivugurura

Muri sisitemu ihujwe na AC, BESS na EVSE bihujwe na bisi nini ya sitasiyo, akenshi kuri 400V cyangwa 480V. BESS ifite sisitemu yayo yo guhindura imbaraga (PCS) ihindura AC kuva kuri grid ikayishyira kuri DC kugira ngo ikoreshwe. Buri shajara ya EV ifite kandi ihindura AC-DC yayo imbere (rectifier).

Akamaro k'ibanze ko guhuza AC ni uburyo ikoresha modularity. Kubera ko BESS n'ibikoresho byo gusana ari ibikoresho byigenga bihujwe na AC grid, bishobora guturuka ku bacuruzi batandukanye kandi bikavugururwa ukwabyo. Ibi bituma guhuza AC ari yo mahitamo meza yo kongera gushyiramo ibikoresho bisanzwe byo gusana. Ariko, imikorere ni mike. Tekereza ku rugero aho EV isharishwa hakoreshejwe ingufu zibitswe muri BESS. Ingufu zigomba kunyura mu byiciro bitatu byo guhindura:

1. Urusobe rw'amashanyarazi (AC) -> BESS PCS (DC) rwo kubikamo.
2. BESS (DC) -> BESS PCS (AC) ijya kuri bisi ya sitasiyo.
3. Gare ya bisi (AC) -> Charger ya EV (DC) ijya ku modoka.

Niba buri cyiciro gifite 95% by'imikorere myiza, imikorere myiza yo gusubira inyuma ni 0.95 * 0.95 * 0.95 = 85.7% gusa. Nubwo ibi byemewe mu kogosha cyane, bigaragaza igihombo gikomeye cy'ingufu mu gihe cy'ingendo ibihumbi n'ibihumbi. Byongeye kandi, sisitemu zifatanye na AC zikenera ibice byinshi, harimo transformers nyinshi na switchgear, ibyo byongera imiterere y'aho sitasiyo ikorera.

1.2 Imiterere y'Ubwubatsi ya DC: Ejo hazaza hagezweho cyane

Sisitemu zihujwe na DC zihuza BESS, imirasire y'izuba ya PV, na charger za EV kuri bisi ya DC ifite voltage nyinshi (ubusanzwe 750V kugeza 1000V). Imashini nini yo hagati ihuza grid na bisi ya DC. Charger za BESS na EV zihuza binyuze mu byuma bihindura DC-DC.

Inyungu nyamukuru hano ni imikorere myiza. Mu gukuraho "urugendo rwo gusubira inyuma" rwa DC-AC-DC, imikorere myiza muri rusange ya sisitemu ishobora kwiyongeraho 5-8%. Guhuza imirasire y'izuba bya PV biroroha cyane kuko inverters za PV zishobora gusimburwa n'ibikoresho bikoresha DC-DC charge controllers byiza cyane binjira muri DC bus. Ubu ni bwo buryo "bwa gakondo" bwo gucunga ingufu za DC zituruka kuri bateri na panels za PV.

Ariko, sisitemu za DC zitera imbogamizi zikomeye mu by’ubuhanga, cyane cyane mu bijyanye no kurinda. Umuyoboro wa DC ntugira "zero-crossing" nka AC, bivuze ko iyo habayeho ikosa, arc ivamo bigorana cyane kuzimya. Ibi bisaba kontakteri za DC zihariye na ultra-fast solid-state circuit breakers (SSCB) zikoresha Silicon Carbide (SiC) MOSFETs kugira ngo zihagarike umuyoboro mu masegonda make. Nubwo hari izi mbogamizi, inganda zirimo kwerekeza ku miterere ya DC-coupled kuri "mega-hubs" nshya, zifite imbaraga nyinshi kubera ubucucike n'imikorere myiza yazo.
