Umahluko osisiseko

Ukuba unesithuthi sombane, kungekudala, uza kudibana nolwazi malunga nokutshaja kwe-AC vs DC. Mhlawumbi sele uqhelene nezi zifinyezo kodwa awazi ukuba zihambelana njani ne-EV yakho.

Eli nqaku liza kukunceda uqonde umahluko phakathi kweetshaja zeDC kunye nezeAC. Emva kokulifunda, uya kwazi nokuba yeyiphi indlela yokutshaja ekhawulezayo kwaye yeyiphi engcono kwimoto yakho.

Masiqalise!

Umahluko #1: Indawo yokuguqula amandla

Kukho iintlobo ezimbini zeetransmitter zombane ezinokusetyenziselwa ukutshaja izithuthi zombane. Zibizwa ngokuba yi-Alternating Current (AC) kunye ne-Direct Current (DC).

Amandla avela kwigridi yombane ahlala eyi-Alternating Current (AC). Nangona kunjalo, ibhetri yemoto yombane inokwamkela i-Direct Current (DC) kuphela. Umahluko ophambili phakathi kokutshaja kwe-AC ne-DC, kukubaindawo apho umbane we-AC uguqulwa khonaIngaguqulwa ngaphandle okanye ngaphakathi emotweni.

Iitshaja zeDC zihlala zinkulu kuba i-converter ingaphakathi kwisikhululo sokutshaja. Oku kuthetha ukuba ikhawuleza kuneetshaja ze-AC xa kufikwa ekutshajeni ibhetri.

Ngokwahlukileyo koko, ukuba usebenzisa i-AC charging, inkqubo yokuguqula iqala ngaphakathi emotweni kuphela. Izithuthi zombane zine-AC-DC converter eyakhelwe ngaphakathi ebizwa ngokuba yi-"onboard charger" eguqula amandla e-AC abe ngamandla e-DC. Emva kokuguqula amandla, ibhetri yemoto iyatshajwa.

Umahluko #2: Ukutshaja ekhaya ngeetshaja ze-AC

Ngokwethiyori, ungafaka itshaja ye-DC ekhaya. Nangona kunjalo, ayinangqondo kangako.

Iitshaja zeDC zibiza kakhulu kuneetshaja zeAC.

Zithatha indawo engakumbi kwaye zifuna iindawo ezingakumbi ezintsonkothileyo kwiinkqubo ezifana nokupholisa okusebenzayo.

Uqhagamshelo lwamandla aphezulu kwigridi yamandla luyimfuneko.

Ngaphezu koko, ukutshaja kwe-DC akukhuthazwa ukuba kusetyenziswe rhoqo - siza kuthetha ngako kamva. Ngenxa yezi nyaniso zonke, ungagqiba kwelokuba itshaja ye-AC yeyona ndlela ingcono yokufakela ikhaya. Iindawo zokutshaja ze-DC zifumaneka kakhulu kwiindlela ezinkulu.

Umahluko #3: Ukutshaja ngeSelfowuni nge-AC

Ziitshaja ze-AC kuphela ezinokuphathwa. Kwaye kukho izizathu ezibini eziphambili zaloo nto:

Okokuqala, itshaja yeDC inesiguquli samandla esinzima kakhulu. Ngoko ke, akunakwenzeka ukuyiphatha xa useluhambeni. Ke ngoko, kukho iimodeli ezimileyo kuphela zetshaja ezinjalo.

Okwesibini, itshaja enjalo ifuna ukufakelwa kwe-480+ volts. Ngoko ke, nokuba ibiyiselula, akunakwenzeka ukuba ufumane umthombo wamandla ofanelekileyo kwiindawo ezininzi. Ngaphezu koko, uninzi lwezikhululo zikawonke-wonke zokutshaja ze-EV zibonelela ngokutshaja kwe-AC, ngelixa iitshaja ze-DC zikwiindlela ezinkulu.

Umahluko #4: Ukutshaja kwe-DC kukhawuleza kunokutshaja kwe-AC

Omnye umahluko obalulekileyo phakathi kokutshaja kwe-AC ne-DC sisantya. Njengoko sele usazi, itshaja ye-DC ine-converter ngaphakathi kwayo. Oku kuthetha ukuba amandla aphuma kwisikhululo sokutshaja se-DC adlula itshaja yemoto ekwibhodi aze aye ngqo ebhetrini. Le nkqubo igcina ixesha kuba i-converter engaphakathi kwitshaja ye-EV isebenza kakuhle kakhulu kuneyo engaphakathi emotweni. Ke ngoko, ukutshaja nge-direct current kunokuba ngokukhawuleza ngokuphindwe kalishumi okanye ngaphezulu kunokutshaja nge-alternating current.

Umahluko #5: Amandla e-AC vs DC – Ijika lokutshaja elahlukileyo

Omnye umahluko obalulekileyo phakathi kokutshaja kwe-AC ne-DC kukumila kwegophe lokutshaja. Kwimeko yokutshaja kwe-AC, amandla athunyelwa kwi-EV ngumgca othe tyaba. Isizathu soku bubungakanani obuncinci betshaja ekwibhodi, kwaye ngokufanelekileyo, amandla ayo alinganiselwe.

Okwangoku, ukutshaja kwe-DC kudala igophe lokutshaja eliwohlokayo, njengoko ibhetri ye-EV ekuqaleni yamkela ukuhamba kwamandla ngokukhawuleza, kodwa kancinci kancinci ifuna okuncinci xa ifikelela kumthamo ophezulu.

Umahluko #6: Ukutshaja kunye nempilo yebhetri

Ukuba kufuneka uthathe isigqibo sokuba uchithe imizuzu engama-30 okanye iiyure ezi-5 utshaja imoto yakho, ukhetho lwakho lucacile. Kodwa akulula kangako, nokuba awukhathali ngomahluko wexabiso phakathi kwe-rapid (DC) kunye ne-regular charging (AC).

Ingongoma kukuba, ukuba itshaja ye-DC isetyenziswa rhoqo, ukusebenza kwebhetri kunye nokuqina kwayo kunokuphazamiseka. Kwaye oku akusiyo nje intsomi eyoyikisayo kwihlabathi le-e-mobility, kodwa sisilumkiso sokwenyani abanye abavelisi beemoto ze-e bade basifake kwiincwadi zabo zemiyalelo.

Uninzi lweemoto ezintsha zombane zixhasa ukutshaja kombane okungaguqukiyo kwi-100 kW nangaphezulu, kodwa ukutshaja ngesi santya kudala ubushushu obugqithisileyo kwaye kwandisa oko kubizwa ngokuba yi-ripple effect - i-AC voltage iyatshintshatshintsha kakhulu kumbane we-DC.

Inkampani ye-telematics ithelekisa impembelelo yeetshaja ze-AC kunye neze-DC. Emva kweenyanga ezingama-48 zokuhlalutya imeko yeebhetri zeemoto zombane, ifumanise ukuba iimoto ezitshaja ngokukhawuleza ngaphezu kwezihlandlo ezithathu ngenyanga kwiimeko zemozulu zamaxesha onyaka okanye ezishushu zazinokonakala kwebhetri nge-10% ngaphezu kwezo zingazange zisebenzise iitshaja ze-DC ezikhawulezayo.

Umahluko #7: Ukutshaja nge-AC kubiza kancinci kunokutshaja nge-DC

Umahluko omkhulu phakathi kokutshaja kwe-AC ne-DC lixabiso — iitshaja ze-AC zibiza kancinci ukuzisebenzisa kuneze-DC. Into kukuba iitshaja ze-DC zibiza kakhulu. Ngaphezu koko, iindleko zokufakela kunye neendleko zoqhagamshelo lwegridi kuzo ziphezulu.

Xa utshaja imoto yakho kwindawo yombane yeDC, ungonga ixesha elininzi. Ngoko ke ifanelekile kwiimeko apho ungxamile. Kwimeko ezinjalo, kufanelekile ukuhlawula ixabiso eliphezulu ngesantya sokutshaja esonyukileyo. Okwangoku, ukutshaja ngombane we-AC kubiza kancinci kodwa kuthatha ixesha elide. Ukuba ungayitshaja imoto yakho ye-EV kufutshane neofisi ngelixa usebenza, umzekelo, akukho mfuneko yokuhlawula ngaphezulu ngokutshaja ngokukhawuleza kakhulu.

Xa kufikwa kwixabiso, ukutshaja ekhaya yeyona ndlela ingabizi kakhulu. Ngoko ke ukuthenga isikhululo sakho sokutshaja sisisombululo esiya kufaneleka ngokuqinisekileyo kwisikhwama sakho.

Ukuqukumbela, zombini ezi ntlobo zokutshaja zinezibonelelo zazo. Ukutshaja kwe-AC ngokuqinisekileyo kusempilweni kwibhetri yemoto yakho, ngelixa uhlobo lwe-DC lungasetyenziselwa iimeko apho kufuneka utshaje ibhetri yakho ngoko nangoko. Ngokwemava ethu, akukho mfuneko yokwenyani yokutshaja ngokukhawuleza, njengoko uninzi lwabanini be-EV betshaja iibhetri zeemoto zabo ebusuku okanye xa bepakwe kufutshane neofisi. Ibhokisi yodonga ye-AC efana ne-go-e Charger Gemini flex okanye i-go-e Charger Gemini, inokuba sisisombululo esihle kakhulu. Ungayifaka ekhaya okanye kwisakhiwo senkampani yakho, okwenza ukuba abasebenzi bakho bakwazi ukutshaja i-EV simahla.

Apha, uza kufumana zonke izinto ezibalulekileyo malunga nokutshaja kwe-AC vs DC kunye nomahluko phakathi kwazo:
