Isiteshi Sokushaja se-AC VS DC

Uma wake wazibuza ukuthi kungani ibizwa ngokuthi “ukushaja okusheshayo kwe-DC,” impendulo ilula. “I-DC” ibhekisela “ku-direct current,” uhlobo lwamandla asetshenziswa amabhethri. Iziteshi zokushaja zezinga lesi-2 zisebenzisa “i-AC,” noma “i-alternating current,” ozoyithola ezindaweni ezivamile zasekhaya. Ama-EV anamashaja angaphakathi emotweni aguqula amandla e-AC abe yi-DC yebhethri. Amashaja okusheshayo e-DC aguqula amandla e-AC abe yi-DC ngaphakathi kwesiteshi sokushaja futhi aletha amandla e-DC ngqo ebhethrini, yingakho eshaja ngokushesha.

Iziteshi zethu ze-ChargePoint Express kanye ne-Express Plus zinikeza ukushaja okusheshayo kwe-DC. Sesha imephu yethu yokushaja ukuze uthole indawo yokushaja okusheshayo eduze kwakho.

Ukushaja Okusheshayo kwe-DC Kuchazwe

Ukushaja kwe-AC kuyindlela elula kakhulu yokushaja ongayithola - izindawo zokuthengisa zikhona yonke indawo futhi cishe wonke amashaja e-EV ohlangana nawo emakhaya, ezindaweni zokuthenga, nasezindaweni zokusebenza angama-Level2 Chargers. Ishaja ye-AC inikeza amandla kushaja engaphakathi kwemoto, iguqula lawo mandla e-AC abe yi-DC ukuze ingene ebhethrini. Izinga lokwamukelwa kweshaja engaphakathi kwemoto liyahlukahluka kuye ngohlobo kodwa lilinganiselwe ngezizathu zezindleko, isikhala kanye nesisindo. Lokhu kusho ukuthi kuye ngemoto yakho kungathatha noma yikuphi kusukela emahoreni amane noma amahlanu kuya emahoreni angaphezu kweshumi nambili ukushaja ngokugcwele ku-Level 2.

Ukushaja okusheshayo kwe-DC kudlula yonke imikhawulo yeshaja esebhodini kanye nokuguqulwa okudingekayo, esikhundleni salokho kunikeza amandla e-DC ngqo ebhethrini, isivinini sokushaja singakhushulwa kakhulu. Izikhathi zokushaja zincike kusayizi webhethri kanye nokukhishwa kwe-dispenser, nezinye izici, kodwa izimoto eziningi ziyakwazi ukuthola ukushaja okungu-80% cishe ngehora noma ngaphansi kwehora zisebenzisa amashaja okusheshayo e-DC atholakalayo njengamanje.

Ukushaja okusheshayo kwe-DC kubalulekile ekushayeleni ibanga elide/ibanga elide kanye nezimoto ezinkulu. Ukushintshashintsha okusheshayo kwenza abashayeli bakwazi ukushaja kabusha emini noma ngesikhathi sekhefu elincane kunokuxhumeka ebusuku, noma amahora amaningi, ukuze bashaje ngokugcwele.

Izimoto ezindala zazinemikhawulo eyayizivumela kuphela ukuthi zishaje ku-50kW kumayunithi e-DC (uma bekwazi) kodwa izimoto ezintsha seziphuma ezingamukela amandla afinyelela ku-270kW. Ngenxa yokuthi usayizi webhethri ukhuphuke kakhulu selokhu ama-EV okuqala afika emakethe, amashaja e-DC abelokhu ethola amandla aphezulu kancane kancane ukuze afane - kanti amanye manje anamandla afinyelela ku-350kW.

Njengamanje, eNyakatho Melika kunezinhlobo ezintathu zokushaja okusheshayo kwe-DC: i-CHAdeMO, i-Combined Charging System (CCS) kanye ne-Tesla Supercharger.

Bonke abakhiqizi abakhulu be-DC charger banikeza amayunithi ajwayelekile anikeza ikhono lokushaja nge-CCS noma i-CHAdeMO kusuka kuyunithi efanayo. I-Tesla Supercharger ingakwazi ukusevisa izimoto ze-Tesla kuphela, noma kunjalo izimoto ze-Tesla ziyakwazi ukusebenzisa amanye amashaja, ikakhulukazi i-CHAdeMO yokushaja okusheshayo kwe-DC, nge-adaptha.

 4.Isiteshi sokushaja se-DC

Isiteshi sokushaja se-DC siyinkimbinkimbi kakhulu ngobuchwepheshe futhi sibiza kakhulu kunesiteshi sokushaja se-AC futhi ngaphezu kwalokho sidinga umthombo onamandla. Ngaphezu kwalokho, isiteshi sokushaja se-DC kumele sikwazi ukuxhumana nemoto esikhundleni seshaja esebhodini ukuze sikwazi ukulungisa amapharamitha wamandla okukhipha ngokuya ngesimo kanye nekhono lebhethri.

Ngokuyinhloko ngenxa yentengo kanye nobunzima bezobuchwepheshe, singabala iziteshi ze-DC ezimbalwa kakhulu kuneziteshi ze-AC. Njengamanje kunamakhulu azo futhi zitholakala emithanjeni emikhulu.

Amandla ajwayelekile esiteshi sokushaja se-DC angama-50kW, okungukuthi ngaphezu kokuphindwe kabili kwesiteshi se-AC. Iziteshi zokushaja ezishesha kakhulu zinamandla afinyelela ku-150 kW, kanti iTesla isungule iziteshi zokushaja ezishesha kakhulu ezikhipha amandla angu-250 kW.

Kodwa-ke, ukushaja kancane usebenzisa iziteshi ze-AC kuthambile kumabhethri futhi kusiza ukuhlala isikhathi eside kwawo, ngakho isu elihle ukushaja ngesiteshi se-AC bese usebenzisa iziteshi ze-DC kuphela ohambweni olude.

Isifinyezo

Ngenxa yokuthi sinezinhlobo ezimbili zamandla kagesi (i-AC ne-DC), kukhona namasu amabili lapho ushaja imoto kagesi.

Kungenzeka ukusebenzisa isiteshi sokushaja se-AC lapho ishaja inakekela khona ukuguqulwa. Lolu khetho luhamba kancane, kodwa lushibhile futhi luthambile. Amashaja e-AC anomphumela ofinyelela ku-22 kW futhi isikhathi esidingekayo sokushaja okugcwele sincike kuphela ekuphumeni kweshaja esebhodini.

Kungenzeka futhi ukusebenzisa iziteshi ze-DC, lapho ukushaja kubiza kakhulu, kodwa kuzokwenzeka ngemizuzu embalwa. Ngokuvamile, amandla azo angama-50 kW, kodwa kulindeleke ukuthi ande esikhathini esizayo. Amandla amashaja asheshayo angama-150 kW. Zombili zitholakala eduze kwemizila emikhulu futhi kufanele zisetshenziswe ohambweni olude kuphela.

Ukuze senze isimo sibe nzima kancane, kunezinhlobo ezahlukene zezixhumi zokushaja, esizethulayo ngokubuka konke. Kodwa-ke, isimo siyashintsha futhi amazinga omhlaba wonke kanye nama-adapter ayavela, ngakho esikhathini esizayo, ngeke kube yinkinga enkulu kakhulu kunezinhlobo ezahlukene zama-socket emhlabeni.
