Izinqwaba zokushaja emakethe zihlukaniswe izinhlobo ezimbili:Ishaja ye-DC neshaja ye-AC.Iningi labathandi bezimoto lingase lingakuqondi.Ake sabelane ngezimfihlo zazo:
Ngokohlelo lwe- "New Energy Vehicle Industry Development Plan (2021-2035)", kuyadingeka ukuthi kusetshenziswe isu likazwelonke lokuthuthukisaizimoto ezintsha zamandlangokujula, sikhuthaze intuthuko yezinga eliphezulu nesimeme yemboni yezimoto zamandla entsha yaseShayina, futhi kusheshiswe ukwakhiwa kwezwe elinamandla lezimoto.Esimeni esinjalo senkathi, ekuphenduleni ukubiza kwezinqubomgomo zikazwelonke, isabelo sezimoto ezintsha zamandla emakethe yezimoto kanye nomdlandla wabathengi wokuthenga ukhula kancane kancane.Ngokusakazwa kabanzi kwezimoto zamandla amasha, izinkinga ezilandelayo zembulwa kancane kancane, futhi eyokuqala inkinga yokushaja!
Izinqwaba zokushajaemakethe zihlukaniswe izinhlobo ezimbili:Ishaja ye-DC neshaja ye-AC.Iningi labathandi bezimoto lingase lingakuqondi, ngakho ngizokutshela kafushane izimfihlo.
1. Umehluko phakathi kwe-DC kanye ne-AC Charger
Inqwaba yokushaja i-AC, ngokuvamile okwaziwa ngokuthi "ukushaja okunensayo", iyidivayisi enikezela ngogesi efakwe ngaphandle kwemoto kagesi futhi ixhunywe kugridi yamandla e-AC ukuze inikeze amandla e-AC eshaja yemoto kagesi engaphakathi ebhodini (okungukuthi, ishaja efakwe ngokuqinile emotweni kagesi. ).IInqwaba yokushaja i-ACihlinzeka kuphela ngokukhipha amandla futhi ayinawo umsebenzi wokushaja.Idinga ukuxhunywa kushaja esebhodini ukuze ishaje imoto kagesi.Kufana nokudlala indima nje ekulawuleni ukunikezwa kwamandla.Isigaba esisodwa/isigaba sesithathu se-AC esiphumayo senqwaba ye-AC siguqulelwa ku-DC ngeshaja esebhodini ukuze ishaje ibhethri elisebhodini.Amandla ngokuvamile mancane (7kw, 22kw, 40kw, njll.), futhi isivinini sokushaja ngokuvamile sihamba kancane.amahora, ngakho-ke ivamise ukufakwa ezindaweni zokupaka izimoto nakwezinye izindawos.
Inqwaba yokushaja i-DC, eyaziwa ngokuthi "ukushaja okusheshayo", iyithuluzi elinikezela ngogesi elifakwe ngokuqinile ngaphandle kwemoto kagesi futhi lixhunywe kugridi yamandla kagesi ye-AC ukunikeza amandla e-DC ebhethri lamandla ezimoto zikagesi ezingaphandle kwebhodi. I-voltage yokufaka yenqwaba yokushaja ye-DC isebenzisa izigaba ezintathu -wire AC 380 V ± 15%, imvamisa engu-50Hz, futhi okukhiphayo kuyi-DC eguquguqukayo, engashaja ngokuqondile ibhethri lamandla emoto kagesi. nikeza amandla anele (60kw, 120kw, 200kw noma ngaphezulu), futhi amandla kagesi aphumayo kanye nobubanzi bamanje bokulungisa bukhulu, obungakwazi ukuhlangabezana nezidingo zokushaja okusheshayo. Kuthatha cishe imizuzu engu-20 kuya ku-150 ukushaja imoto ngokugcwele, ngakho-ke ngokuvamile efakwe atIsiteshi sokushaja se-EVeduze komgwaqo onguthelawayeka wezidingo zezikhathi ezithile zabasebenzisi endleleni.
Izinzuzo kanye Nemibi
Okokuqala, izindleko ze-AC zokushaja izinqwaba ziphansi, ukwakhiwa kulula, futhi izidingo zomthwalo ku-transformer azinkulu, futhi amakhabhinethi okusabalalisa amandla emphakathini angafakwa ngokuqondile.Isakhiwo esilula, usayizi omncane, singalengiswa odongeni, siphathekayo futhi singathwalwa emotweni.Amandla amakhulu wokushaja wenqwaba yokushaja kwe-AC ngu-7KW.Uma nje kuyimoto kagesi, ngokuvamile isekela ukushaja kwe-AC.Izimoto zikagesi zinezimbobo zokushaja ezimbili, enye iyi-interface yokushaja esheshayo kanti enye iyisixhumi esibonakalayo sokushaja okunensayo.Ukusebenzelana kokushaja kwezinye izimoto zikagesi ezijwayelekile okungezona ezezwe zingasebenzisa i-AC kuphela, futhi izinqwaba zokushaja ze-DC azikwazi ukusetshenziswa.
I-voltage yokufaka yenqwaba yokushaja ye-DC ingu-380V, amandla ngokuvamile angaphezu kuka-60kw, futhi kuthatha imizuzu engu-20-150 kuphela ukushaja ngokugcwele.Izinqwaba zokushaja i-DC zifanele izimo ezidinga isikhathi sokushaja esiphezulu, njengeziteshi zokushaja zezimoto ezisebenzayo njengamatekisi, amabhasi, nezimoto zokuthutha, kanye nezinqwaba zokushaja zomphakathi zezimoto zabagibeli.Kodwa izindleko zayo zidlula kude inqwaba yokushintshisana.Izinqwaba ze-DC zidinga ama-transformer anevolumu enkulu kanye namamojula wokuguqula we-AC-DC.Izindleko zokukhiqiza nokufakwa kwezinqwaba zokushaja zingaba ngu-0.8 RMB/watt, kanti inani lentengo lama-60kw DC piles lilinganiselwa ku-50,000 RMB (ngaphandle kobunjiniyela bomphakathi kanye nokwandiswa kwamandla).Ukwengeza, iziteshi ezinkulu zokushaja ze-DC zinomthelela othile kugridi yamandla, futhi ubuchwepheshe bokuvikela bamanje kanye nezindlela ziyinkimbinkimbi, futhi izindleko zokuguqulwa, ukufakwa nokusebenza ziphakeme.Futhi ukufakwa nokwakhiwa kuyinkinga kakhulu.Ngenxa yamandla amakhulu okushaja wenqwaba yokushaja kwe-DC, izidingo zokunikezwa kwamandla ziphakeme kakhulu, futhi i-transformer kufanele ibe nomthamo owanele wokulayisha ukusekela amandla amakhulu kangaka.Imiphakathi eminingi emidala ayinazo izintambo kanye nama-transformer abekwe kusengaphambili.enemibandela yokufaka.Kukhona nokulimala kwebhethri lamandla.Ukukhishwa kwamanje kwenqwaba ye-DC kukhulu, futhi ukushisa okwengeziwe kuzokhishwa ngesikhathi sokushaja.Izinga lokushisa eliphezulu lizoholela ekwehleni okungazelelwe komthamo webhethri lamandla kanye nokulimala kwesikhathi eside kuseli yebhethri.
Ukufingqa, izinqwaba zokushaja ze-DC kanye nezinqwaba zokushaja ze-AC ngayinye inezinzuzo zayo kanye nokubi, futhi ngayinye inezimo zayo zohlelo lokusebenza.Uma kungumphakathi osanda kwakhiwa, kuphephile ukuhlela ngokuqondile izinqwaba zokushaja ze-DC, kodwa uma kunemiphakathi emidala, sebenzisa indlela yokushaja yezinqwaba zokushaja ze-AC, ezingahlangabezana nezidingo zokushaja zabasebenzisi futhi ngeke zidale umonakalo omkhulu i-transformer kumthwalo womphakathi.
