Sitasiyo yo gushyushya AC VS DC

Niba wigeze kwibaza impamvu yitwa "DC fast charger," igisubizo ni cyoroshye. "DC" yerekeza ku "direct current," ubwoko bw'ingufu bateri zikoresha. Urwego rwa 2 rwo gushyushya rukoresha "AC," cyangwa "alternating current," uzasanga mu maduka asanzwe yo mu rugo. EV zifite charger ziri mu modoka zihindura ingufu za AC muri DC kuri bateri. charger za DC fast zihindura ingufu za AC muri DC muri station yo gushyushya kandi zigatanga ingufu za DC kuri bateri, ari nayo mpamvu zishyushya vuba.

Sitasiyo zacu za ChargePoint Express na Express Plus zitanga DC fasting yihuse. Shakisha ku ikarita yacu yo chargering kugira ngo ubone ahantu ho chargering yihuse hafi yawe.

Gutanga charge yihuta bya DC byasobanuwe

Gushaja AC ni bwo buryo bworoshye bwo gushaja - amasoko ari hose kandi hafi ya charger zose za EV uhura nazo mu ngo, ku masoko, no ku kazi ni Level 2 Chargers. Charger ya AC itanga ingufu kuri charger iri mu modoka, igahindura iyo AC muri DC kugira ngo yinjire muri batiri. Igipimo cyo kwakira charger iri mu modoka gitandukanye bitewe n'ikirango ariko ni gito bitewe n'igiciro, umwanya n'uburemere. Ibi bivuze ko bitewe n'imodoka yawe, bishobora gufata amasaha kuva kuri ane cyangwa atanu kugeza ku masaha arenga cumi n'abiri kugira ngo charger yuzuye ku Level 2.

DC Fast Charging inyura ku nzitizi zose za charger iri mu bwato ndetse n'impinduka zikenewe, ahubwo igatanga ingufu za DC kuri bateri, umuvuduko wo charger ushobora kwiyongera cyane. Igihe cyo charger giterwa n'ingano ya bateri n'umusaruro w'icyuma gitanga umuriro, n'ibindi bintu, ariko imodoka nyinshi zishobora kubona charger ya 80% mu isaha imwe cyangwa munsi yayo hakoreshejwe charger za DC Fast Charger ziboneka ubu.

Gukoresha DC byihuse ni ingenzi ku modoka zitwara ibirometero byinshi cyangwa intera ndende ndetse no ku modoka nini. Gukoresha DC byihuse bituma abashoferi bashobora kongera ingufu mu gihe cy'umunsi cyangwa mu kiruhuko gito aho gukoresha amashanyarazi mu ijoro ryose, cyangwa amasaha menshi, kugira ngo bakoreshe umuriro wose.

Imodoka zishaje zari zifite imbogamizi zazemereraga gusa gushyushya 50kW kuri DC units (niba zari zibishoboye) ariko ubu imodoka nshya zirimo gusohoka zishobora kwakira 270kW. Kubera ko ingano ya bateri yiyongereye cyane kuva EV za mbere zagera ku isoko, DC chargers zagiye zirushaho kugira umusaruro mwinshi uhuye na zo - zimwe ubu zikaba zifite ubushobozi bwo kugeza kuri 350kW.

Muri iki gihe, muri Amerika ya Ruguru hari ubwoko butatu bwa DC fast charger: CHAdeMO, Combined Charging System (CCS) na Tesla Supercharger.

Inganda zose zikomeye zikora charger za DC zitanga ibikoresho bigezweho bitanga ubushobozi bwo gusharija binyuze kuri CCS cyangwa CHAdeMO biva muri mashini imwe. Tesla Supercharger ishobora gusa gukorera imodoka za Tesla, ariko imodoka za Tesla zishobora gukoresha izindi charger, cyane cyane CHAdeMO mu gusharija vuba bya DC, binyuze kuri adaptateri.

 4.Sitasiyo yo gushyushya ya DC

Sitasiyo yo gusharija ya DC mu ikoranabuhanga iragoye cyane kandi ihenze inshuro nyinshi kurusha sitasiyo yo gusharija ya AC kandi ikenera isoko rikomeye. Byongeye kandi, sitasiyo yo gusharija ya DC igomba kuba ishobora kuvugana n'imodoka aho kuvugana n'icyuma gishyushya umuriro kiri mu modoka kugira ngo ibashe guhindura ibipimo by'ingufu zisohoka hakurikijwe imiterere n'ubushobozi bwa bateri.

Bitewe ahanini n'igiciro n'ubuhanga mu ikoranabuhanga, dushobora kubara sitasiyo za DC nke cyane ugereranyije na sitasiyo za AC. Ubu hariho amagana yazo kandi ziherereye ku miyoboro mikuru.

Ingufu zisanzwe za sitasiyo yo gusharija ya DC ni 50kW, ni ukuvuga inshuro zirenze ebyiri ugereranyije na sitasiyo ya AC. Sitasiyo zo gusharija zihuta cyane zifite imbaraga zigera kuri 150 kW, naho Tesla yashyizeho sitasiyo zo gusharija zihuta cyane zifite ingufu zigera kuri 250 kW.

Ariko, gusharija buhoro ukoresheje sitasiyo za AC byoroshye kuri batiri kandi bibafasha kuramba, bityo ingamba nziza ni ugushyushya ukoresheje sitasiyo za AC no gukoresha sitasiyo za DC gusa mu ngendo ndende.

Incamake

Bitewe nuko dufite ubwoko bubiri bw'amashanyarazi (AC na DC), hari kandi ingamba ebyiri zo gusharija imodoka ikoresha amashanyarazi.

Birashoboka gukoresha sitasiyo yo gusharija ya AC aho charger yita ku guhindura. Ubu buryo buragenda buhoro, ariko buhendutse kandi bworoshye. charger za AC zifite umuvuduko wa 22 kW kandi igihe gisabwa kugira ngo charger yuzuye giterwa gusa n'umuvuduko wa charger iri mu ndege.

Birashoboka kandi gukoresha sitasiyo za DC, aho gusharija bihenze cyane, ariko bizakorwa mu minota mike. Ubusanzwe, umusaruro wazo ni 50 kW, ariko byitezwe ko uziyongera mu gihe kizaza. Ingufu za charger zihuta ni 150 kW. Zombi ziherereye hafi y'inzira nkuru kandi zigomba gukoreshwa mu ngendo ndende gusa.

Kugira ngo ibintu birusheho kugorana, hari ubwoko butandukanye bw'imiyoboro yo gusharija, incamake y'ibyo tubagezaho. Ariko, ibintu birimo guhinduka kandi amahame mpuzamahanga na adaptateri birimo kugaragara, bityo mu gihe kizaza, ntibizaba ikibazo gikomeye kurusha ubwoko butandukanye bw'imiyoboro ku isi.
