AC VS DC Kuchaja Chiteshi

Kana wakambozvibvunza kuti sei ichinzi "DC kukurumidza kuchaja," mhinduro iri nyore. “DC” inoreva “direct current,” rudzi rwesimba rinoshandiswa nemabhatiri. Level 2 yekuchaja zviteshi zvinoshandisa “AC,” kana “alternating current,” iyo yaunowana mudzimba dzinotengeswa. MaEV ane machaja ari mukati memota anoshandura AC simba kuita DC yebhatiri. DC inokurumidza majaja anoshandura AC simba kuita DC mukati mechiteshi chekuchaja uye kuendesa DC simba rakananga kubhatiri, ndosaka vachichaja nekukurumidza.

Yedu ChargePoint Express uye Express Plus zviteshi zvinopa DC nekukurumidza kuchaja. Tsvaga mepu yedu yekuchaja kuti uwane inokurumidza kuchaja iri pedyo newe.

DC Inokurumidza Kuchaja Inotsanangurwa

AC kuchaja ndiyo yakapusa mhando yekuchaja kuwana - zvitoro zviri kwese kwese uye dzinenge dzese maEV majaja aunosangana nawo mudzimba, nzvimbo dzekutengesera, uye kumabasa maLevel2 Charger. Iyo AC charger inopa simba kune-bhodhi charger yemotokari, ichishandura iyo AC simba kuita DC kuitira kuti ipinde mubhatiri. Mwero wekugamuchirwa wepa-board charger unosiyana nerudzi asi unoganhurwa nezvikonzero zvemutengo, nzvimbo uye huremu. Izvi zvinoreva kuti zvichienderana nemotokari yako zvinogona kutora chero kubva pamaawa mana kana mashanu kusvika anopfuura maawa gumi nemaviri kuti inyatsochaja paChikamu chechipiri.

DC Inokurumidza Kuchaja inodarika zvese zvinogumira pane-bhodhi charger uye inodiwa shanduko, pachinzvimbo ichipa DC simba rakananga kubhatiri, yekuchaja kumhanya ine mukana wekuwedzera zvakanyanya. Nguva dzekuchaja dzinoenderana nesaizi yebhatiri uye kubuda kwemudziyo, uye zvimwe zvinhu, asi mota zhinji dzinokwanisa kuwana 80% yekuchaja mukati kana pasi peawa vachishandisa akawanda aripo parizvino DC anokurumidza kuchaja.

DC yekuchaja nekukurumidza kwakakosha kune yakakwira mamaira / kureba kutyaira uye mahombe ngarava. Iko kukurumidza kutendeuka kunoita kuti vatyairi vakwanise kuchaja mukati mezuva ravo kana pazororo diki kupesana nekubatirwa mukati mehusiku humwe, kana kwemaawa mazhinji, kubhadharisa yakazara.

Mota dzechikuru dzaive neganhuriro dzaingovabvumira kuchaja pa50kW pazvikamu zveDC (kana vaikwanisa zvachose) asi mota itsva dzava kubuda dzinogona kugamuchira kusvika ku270kW. Nekuti saizi yebhatiri yakawedzera zvakanyanya kubva maEV ekutanga asvika pamusika, majaja eDC anga achiwana mibairo yepamusoro kuti ienderane - vamwe vave kukwanisa kusvika 350kW.

Parizvino, kuNorth America kune marudzi matatu eDC yekuchaja nekukurumidza: CHAdeMO, Combined Charging System (CCS) uye Tesla Supercharger.

Vese vakuru vanogadzira majaja eDC vanopa akawanda-akajairwa mayunitsi anopa kugona kuchaja kuburikidza neCCS kana CHAdeMO kubva kune imwecheteyo unit. Iyo Tesla Supercharger inogona kushandira Tesla mota chete, zvisinei mota dzeTesla dzinokwanisa kushandisa mamwe majaja, kunyanya CHAdeMO yeDC yekuchaja nekukurumidza, kuburikidza neadapter.

 4.DC yekuchaja chiteshi

Chiteshi chekuchaja cheDC chakaoma tekinoroji uye kakawanda inodhura kupfuura chiteshi chekuchaja cheAC uyezve inoda sosi ine simba. Pamusoro pezvo, DC yekuchaja chiteshi inofanirwa kutaurirana nemota pachinzvimbo che-on-board charger kuitira kuti ikwanise kugadzirisa inobuda simba paramita zvinoenderana nemamiriro uye kugona kwebhatiri.

Kunyanya nekuda kwemutengo uye kuoma kwetekinoroji, tinogona kuverenga mashoma DC zviteshi pane AC zviteshi. Parizvino kune mazana azvo uye anowanikwa patsinga huru.

Simba rakajairwa reDC yekuchaja chiteshi i50kW, kureva kuti rinopfuura kaviri rechiteshi che AC. Zviteshi zvekuchaja zvehurefu zvine simba rinosvika 150 kW, uye Tesla yakagadzira zviteshi zvekuchaja zvemhando yepamusoro-soro zvine 250 kW.

Nekudaro, kunonoka kuchaja uchishandisa AC zviteshi zvine hunyoro kumabhatiri uye zvinobatsira hupenyu hwavo hurefu, saka zano rakakodzera nderekuchaja kuburikidza neAC chiteshi uye kushandisa DC zviteshi panzendo refu chete.

Summary

Nekuda kwekuti isu tine marudzi maviri ezvino (AC neDC), kune zvakare nzira mbiri pakuchaja mota yemagetsi.

Zvinogoneka kushandisa AC yekuchaja chiteshi uko charger inotarisira kutendeuka. Iyi sarudzo inononoka, asi yakachipa uye yakapfava. Machaja eAC ane kubuda kunosvika 22 kW uye nguva inodiwa pakuchaja izere inobva yangoenderana nekubuda kwechaja iri pabhodhi.

Zvinogonekawo kushandisa zviteshi zveDC, uko kuchaja kunodhura, asi kuchaitika mukati memaminitsi mashoma. Kazhinji, kuburitsa kwavo i50 kW, asi inotarisirwa kuwedzera mune ramangwana. Simba rekukurumidza majaja i150 kW. Ose ari maviri anowanikwa akatenderedza nzira huru uye anofanirwa kushandiswa nzendo refu chete.

Kuita kuti mamiriro acho awedzere kuoma, kune marudzi akasiyana ezvibatanidza zvekuchaja, mhedziso yatinopa. Zvisinei, mamiriro ezvinhu ari kuchinja uye mitemo yepasi rose uye adapters iri kubuda, saka mune ramangwana, hazvizove dambudziko guru kudarika marudzi akasiyana-siyana ezvigadziko munyika.
