AC VS DC Yishyuza

Niba warigeze kwibaza impamvu yitwa "DC byihuse," igisubizo kiroroshye. “DC” bivuga “umuyoboro utaziguye,” ubwoko bw'imbaraga bateri zikoresha. Urwego rwa 2 rwo kwishyuza rukoresha "AC," cyangwa "guhinduranya amashanyarazi," uzasanga mubicuruzwa bisanzwe murugo. EV zifite charger zimbere mumodoka zihindura ingufu za AC kuri DC kuri bateri. Amashanyarazi yihuta ya DC ahindura ingufu za AC muri DC muri sitasiyo yumuriro kandi igatanga ingufu za DC kuri bateri, niyo mpamvu zishyuza vuba.

Sitasiyo yacu ya ChargePoint Express na Express Plus itanga DC kwishyuza byihuse. Shakisha ikarita yacu yo kwishyuza kugirango ubone ahantu hihuta cyane.

DC Kwishyuza Byihuse Byasobanuwe

Kwishyuza AC nuburyo bworoshye bwo kwishyuza kubona - ahacururizwa harahantu hose kandi hafi ya EV charger zose uhura nazo murugo, ibibuga byubucuruzi, hamwe n’aho ukorera ni urwego rwa 2 rwishyuza. Amashanyarazi ya AC atanga imbaraga kumashanyarazi yimodoka, ahindura ingufu za AC muri DC kugirango yinjire muri bateri. Igipimo cyo kwakirwa cyumuriro wubwato kiratandukana kubirango ariko bigarukira kubwimpamvu zigiciro, umwanya nuburemere. Ibi bivuze ko ukurikije imodoka yawe bishobora gufata ahantu hose kuva amasaha ane cyangwa atanu kugeza kumasaha arenga cumi n'abiri kugirango yishyure byuzuye kurwego rwa 2.

DC Kwishyuza byihuse kurenga imbogamizi zose zumuriro wubwato kandi bisabwa guhinduka, aho gutanga ingufu za DC kuri bateri, umuvuduko wo kwishyiriraho ufite ubushobozi bwo kwiyongera cyane. Ibihe byo kwishyuza biterwa nubunini bwa bateri nibisohoka bya dispenser, nibindi bintu, ariko ibinyabiziga byinshi birashobora kubona 80% mugihe kingana cyangwa munsi yisaha ukoresheje amashanyarazi yihuta ya DC aboneka.

Amashanyarazi ya DC ningirakamaro kuri mileage / intera ndende yo gutwara hamwe na flet nini. Ihinduka ryihuse rifasha abashoferi kwishyuza kumunsi wabo cyangwa kuruhuka ruto bitandukanye no gucomeka ijoro ryose, cyangwa amasaha menshi, kugirango bishyure byuzuye.

Imodoka zishaje zari zifite aho zibogamiye zemerera kwishyuza 50kW gusa kuri DC (niba zarashoboye na gato) ariko ubu imodoka nshya zirasohoka zishobora kwakira 270kW. Kubera ko ingano ya batiri yiyongereye cyane kuva EV ya mbere yagera ku isoko, charger za DC zagiye zigenda ziyongera cyane kugirango zihuze - hamwe na hamwe ubu zishobora kugera kuri 350kW.

Kugeza ubu, muri Amerika ya Ruguru hari ubwoko butatu bwa DC bwihuta: CHAdeMO, Sisitemu yo Kwishyuza (CCS) na Tesla Supercharger.

Abakora amashanyarazi bose ba DC batanga ibice byinshi-bitanga ubushobozi bwo kwishyuza binyuze muri CCS cyangwa CHAdeMO kuva murwego rumwe. Tesla Supercharger irashobora gukorera gusa imodoka za Tesla, icyakora imodoka za Tesla zirashobora gukoresha izindi charger, cyane cyane CHAdeMO kugirango DC yishyure vuba, ikoresheje adapt.

 4.Sitasiyo ya DC

Sitasiyo ya DC yumuriro irakomeye muburyo bwikoranabuhanga kandi inshuro nyinshi zihenze kuruta sitasiyo yumuriro wa AC kandi byongeye bisaba isoko ikomeye. Byongeye kandi, sitasiyo ya DC igomba kuba ishobora kuvugana n imodoka aho kuba charger yo mu ndege kugirango ibashe guhindura ibipimo byingufu zisohoka ukurikije imiterere nubushobozi bwa bateri.

Ahanini bitewe nigiciro hamwe nubuhanga bugoye, turashobora kubara sitasiyo ya DC nkeya ugereranije na AC. Kugeza ubu hari amagana yabyo kandi aherereye kumitsi nyamukuru.

Imbaraga zisanzwe za DC yumuriro ni 50kW, ni ukuvuga inshuro zirenze ebyiri za sitasiyo ya AC. Sitasiyo ya Ultra-yihuta ifite ingufu zingana na kilowati 150, kandi Tesla yateje imbere super-ultra-mega yihuta yumuriro hamwe na 250 kWt.

Nyamara, kwishyuza gahoro ukoresheje sitasiyo ya AC biroroshye kuri bateri kandi bifasha kuramba, ingamba nziza rero nukwishyuza ukoresheje AC hanyuma ugakoresha sitasiyo ya DC gusa murugendo rurerure.

Incamake

Bitewe nuko dufite ubwoko bubiri bwumuriro (AC na DC), hariho nuburyo bubiri mugihe twishyuza imodoka yamashanyarazi.

Birashoboka gukoresha sitasiyo yumuriro wa AC aho charger yita kubihinduka. Ihitamo riratinda, ariko rihendutse kandi ryoroheje. Amashanyarazi ya AC afite umusaruro ugera kuri 22 kWt kandi igihe gisabwa kugirango yishyure byuzuye noneho biterwa gusa nibisohoka mumashanyarazi.

Birashoboka kandi gukoresha sitasiyo ya DC, aho kwishyuza bihenze, ariko bizabera muminota mike. Mubisanzwe, umusaruro wabo ni 50 kWt, ariko biteganijwe ko uziyongera mugihe kizaza. Imbaraga za charger zihuta ni 150 kWt. Byombi biherereye hafi yinzira nkuru kandi bigomba gukoreshwa murugendo rurerure gusa.

Kugirango ibintu birusheho kuba ingorabahizi, hariho ubwoko butandukanye bwo kwishyuza, incamake twerekana. Nubwo bimeze bityo ariko, ibintu biragenda bihinduka kandi amahame mpuzamahanga hamwe na adapteri bigenda bigaragara, bityo mugihe kizaza, ntabwo bizaba ikibazo kinini cyane kuruta ubwoko butandukanye bwa socket kwisi.
