Umehluko Oyisisekelo

Uma ungumnikazi wemoto kagesi, maduze noma kamuva, uzohlangana nolunye ulwazi mayelana nokushajwa kwe-AC vs DC. Mhlawumbe, usuvele ujwayelene nalezi zifinyezo kodwa awunalwazi lokuthi zihlobana kanjani ne-EV yakho.

Lesi sihloko sizokusiza uqonde umehluko phakathi kwamashaja e-DC kanye ne-AC. Ngemva kokuyifunda, uzokwazi futhi ukuthi iyiphi indlela yokushaja esheshayo nokuthi iyiphi engcono emotweni yakho.

Ake siqale!

Umehluko #1: Indawo Yokuguqula Amandla

Kunezinhlobo ezimbili zama-transmitter kagesi angasetshenziswa ukushaja izimoto zikagesi. Abizwa ngokuthi Alternating Current (AC) kanye namandla a-Direct Current (DC).

Amandla aphuma kugridi kagesi ahlala e-Alternating Current (AC). Nokho, ibhethri lemoto kagesi likwazi ukwamukela i-Direct Current (DC) kuphela. Umehluko omkhulu phakathi kokushaja kwe-AC ne-DC, iindawo lapho amandla e-AC aguqulwa khona. Ingashintshwa ngaphandle noma ngaphakathi emotweni.

Amashaja e-DC ngokuvamile abamakhulu njengoba isiguquli singaphakathi kwesiteshi sokushaja. Lokhu kusho ukuthi ishesha kunamashaja e-AC uma kukhulunywa ngokushaja ibhethri.

Ngokuphambene, uma usebenzisa ukushaja kwe-AC, inqubo yokuguqula iqala kuphela ngaphakathi kwemoto. Izimoto zikagesi zinesiguquli se-AC-DC esakhelwe ngaphakathi esibizwa ngokuthi “ishaja engaphakathi kwebhodi” eguqula amandla e-AC abe amandla e-DC. Ngemva kokuguqula amandla, ibhethri lemoto liyashajwa.

Umehluko #2: Ukushaja Ekhaya Ngamashaja E-AC

Ngokwethiyori, ungafaka ishaja ye-DC ekhaya. Nokho, akuwenzi umqondo omkhulu.

Amashaja e-DC abiza kakhulu kunamashaja e-AC.

Zithatha isikhala esiningi futhi zidinga izingxenye eziyisipele eziyinkimbinkimbi kakhulu zezinqubo ezifana nokupholisa okusebenzayo.

Ukuxhumeka kwamandla aphezulu kugridi yamandla kuyadingeka.

Ngaphezu kwalokho, ukushaja kwe-DC akunconywa ukuthi kusetshenziswe njalo - sizokhuluma ngalokhu kamuva. Ngokunikezwa kwawo wonke lawa maqiniso, ungaphetha ngokuthi ishaja ye-AC iyisinqumo esingcono kakhulu sokufakwa ekhaya. Izindawo zokushaja ze-DC zitholakala kakhulu emigwaqweni emikhulu.

Umehluko #3: Ukushaja Iselula nge-AC

Amashaja e-AC kuphela angaba yiselula. Futhi kunezizathu ezimbili eziyinhloko zayo:

Okokuqala, ishaja ye-DC iqukethe isiguquli esinda kakhulu samandla. Ngakho-ke, ukuthwala nawe ohambweni akunakwenzeka. Ngakho-ke, amamodeli amile kuphela amashaja anjalo akhona.

Okwesibili, ishaja enjalo idinga okokufaka okungu-480+ volts. Ngakho-ke, noma ngabe ibihamba, ngeke ukwazi ukuthola umthombo wamandla ofanelekile ezindaweni eziningi. Ngaphezu kwalokho, iningi leziteshi zokushaja ze-EV zomphakathi zihlinzeka ngokushaja kwe-AC, kuyilapho amashaja e-DC ahambisana nemigwaqo emikhulu.

Umehluko #4: Ukushaja kwe-DC Kuyashesha kunokushaja kwe-AC

Omunye umehluko obalulekile phakathi kokushaja kwe-AC ne-DC ijubane. Njengoba wazi kakade, ishaja ye-DC ine-converter ngaphakathi kwayo. Lokhu kusho ukuthi amandla aphuma esiteshini sokushaja se-DC edlula ishaja yemoto engaphakathi bese engena ngqo ebhethrini. Le nqubo iyonga isikhathi njengoba isiguquli esingaphakathi kweshaja ye-EV sisebenza kahle kakhulu kunalena engaphakathi emotweni. Ngakho-ke, ukushaja ngomsinga oqondile kungashesha izikhathi eziyishumi noma ngaphezulu kunokushaja ngokushintshana kwamandla.

Umehluko #5: I-AC vs DC Power – Ijika Elihlukile Lokushaja

Omunye umehluko obalulekile phakathi kokushaja kwe-AC ne-DC ukuma kwejika lokushaja. Esimeni sokushajwa kwe-AC, amandla alethwa ku-EV awumugqa oyisicaba nje. Isizathu salokhu usayizi omncane weshaja engaphakathi futhi, ngokufanele, amandla ayo alinganiselwe.

Ngaleso sikhathi, ukushaja kwe-DC kudala ijika lokushaja elilulazayo, njengoba ibhethri ye-EV ekuqaleni yamukela ukugeleza kwamandla okusheshayo, kodwa kancane kancane idinga okuncane uma ifinyelela umthamo omkhulu.

Umehluko #6: Ukushaja kanye Nempilo Yebhethri

Uma kufanele unqume ukuthi uzochitha imizuzu engu-30 noma amahora angu-5 ushaja imoto yakho, ukukhetha kwakho kusobala kakhulu. Kodwa akulula kangako, ngisho noma ungenandaba nomehluko wamanani phakathi kokushaja okusheshayo (DC) nokushaja okuvamile (AC).

Into ewukuthi, uma ishaja ye-DC isetshenziswa ngokuqhubekayo, ukusebenza kwebhethri nokuqina kungase kuphazamiseke. Futhi lokhu akuyona nje inganekwane ethusayo emhlabeni we-e-mobility, kodwa isixwayiso sangempela abanye abakhiqizi be-e-car baze basifake kumamanuwali wabo.

Izimoto eziningi zikagesi ezintsha zisekela ukushaja okungaguquki kwamanje ku-100 kW noma ngaphezulu, kodwa ukushaja ngalesi sivinini kudala ukushisa okudlulele futhi kukhulisa lokho okubizwa ngokuthi umphumela we-ripple - i-voltage ye-AC ishintshashintsha kakhulu kugesi we-DC.

Inkampani ye-telematics eqhathanisa umthelela wamashaja e-AC kanye ne-DC. Ngemva kwezinyanga ezingu-48 zokuhlaziya isimo samabhethri emoto kagesi, ithole ukuthi izimoto ezisebenzisa ukushaja ngokushesha izikhathi ezingaphezu kwezintathu ngenyanga esimweni sezulu esishisayo noma esishisayo zibe nokuwohloka kwamabhethri ngo-10% ngaphezu kwalawo angakaze asebenzise amashaja asheshayo e-DC.

Umehluko #7: Ukushaja kwe-AC Kushibhile kunokushaja kwe-DC

Umehluko owodwa obalulekile phakathi kokushaja kwe-AC ne-DC inani lentengo — Amashaja e-AC ashibhe kakhulu ukuwasebenzisa kunawase-DC. Into ukuthi amashaja e-DC abiza kakhulu. Ngaphezu kwalokho, izindleko zokufaka nezindleko zokuxhuma igridi kubo ziphakeme.

Uma ushaja imoto yakho endaweni yamandla e-DC, ungonga isikhathi esiningi. Ngakho-ke ilungele izimo lapho ujahile khona. Ezimweni ezinjalo, kunengqondo ukukhokha inani eliphakeme lokwenyuka kwesivinini sokushaja. Okwamanje, ukushaja ngamandla e-AC ishibhile kodwa kuthatha isikhathi eside. Uma ungakwazi ukushaja i-EV yakho eduze nehhovisi ngenkathi usebenza, isibonelo, asikho isidingo sokukhokha ngokweqile ngokushaja okushesha kakhulu.

Uma kuziwa enanini, ukushaja kwasekhaya iyona ndlela eshibhe kakhulu. Ngakho-ke ukuthenga isiteshi sakho sokushaja kuyisixazululo esizofanelana nesikhwama sakho semali.

Ukuphetha, zombili izinhlobo zokushaja zinezinzuzo zazo. Ukushaja i-AC kunempilo ebhethri lemoto yakho, kuyilapho okuhlukile kwe-DC kungasetshenziselwa izimo lapho udinga ukushajwa kabusha ibhethri lakho ngokushesha. Kusukela kokuhlangenwe nakho kwethu, asikho isidingo sangempela sokushaja okusheshayo, njengoba abanikazi be-EV abaningi bashaja amabhethri ezimoto zabo ebusuku noma lapho ipake eduze nehhovisi. I-wallbox ye-AC efana ne-go-e Charger Gemini flex noma i-go-e Charger Gemini, ngakho-ke ingaba yisixazululo esihle kakhulu. Ungayifaka ekhaya noma esakhiweni senkampani yakho, wenze ukushaja kwe-EV kwamahhala kusebenzele abasebenzi bakho.

Lapha, uzothola zonke izinto ezibalulekile mayelana nokushaja kwe-AC vs DC kanye nomehluko phakathi kwakho:
