I-Beihai Powder, inkokheli kwizisombululo ezintsha zokutshaja ii-EV, iyazingca ngokwazisa "Itshaja ye-DC encinci engama-20kw-40kw"–isisombululo esitshintsha umdlalo esenzelwe ukuvala umsantsa phakathi kokutshaja kwe-AC okucothayo kunyeukutshaja ngokukhawuleza kwe-DC enamandla aphezuluYenzelwe ukuguquguquka, ukufikeleleka, kunye nesantya, le tshaja inika amandla amashishini kunye noluntu ukuba bamkele ukuhamba okuzinzileyo ngaphandle kokuphazamisa ukusebenza kakuhle.
Iitshaja zeDC ezincinci(20kW-40kW) zibonelela ngeenzuzo ezibalulekileyo kunezo zinamandla aphezulu zemveliIitshaja zeDC(120kW+). Ziyabiza kancinci kwaye ziphantsi iindleko zokufakela ngenxa yokuphuculwa okuncinci kwegridi. Ukusetyenziswa kwazo kwamandla okuphakathi kunciphisa iindleko zokusebenza, nto leyo enika i-ROI ekhawulezayo (iinyanga ezi-6-18). Iitshaja ezinamandla aphezulu zibiza kakhulu kwaye zifuna iziseko zophuhliso ezibanzi kwaye zinexesha elide le-ROI (iminyaka emi-2-5).
Iitshaja zeDC ezincinci zilungelelaniswa lula, zisebenza kwiisekethe eziqhelekileyo ze-220V-380V kunye neendawo ezincinci zokudibanisa (0.5-1).㎡Zisebenza kwiintsuku ezi-1-3, zilungele iivenkile ezinkulu, iiofisi, kunye neehotele. Iitshaja ezinamandla aphezulu zifuna iisekethe ze-voltage ephezulu kwaye zithatha inyanga e-1-3 ukufakelwa, nto leyo ebathintela kwiindlela ezinkulu nakwizikhululo ezizinikeleyo.
Ngesantya sokutshaja se-20-50kW (100-250 km/h), iitshaja ze-DC ezincinci zilungele ii-EV ezincinci ukuya kweziphakathi (≤80kWh) kwaye sebenzisa iinkqubo zokupholisa ezilula, ukuqinisekisa ukuthembeka kunye nobomi beminyaka esi-8 ukuya kweli-10.Isitishi sokutshaja seDC(120-350kW, 500-1000 km/h) ilungele ii-EV ezinkulu (≥100kWh) kodwa ixhomekeke ekupholiseni ulwelo oluntsonkothileyo, okonyusa amazinga okusilela kunye nokunciphisa ubomi ukuya kwiminyaka emi-5-8.
Iitshaja zeDC ezincinci zibalasele kwiindawo zorhwebo nezoluntu, zibonelela ngokutshaja okufikelelekayo kwiinqwelomoya (umz., iiteksi, ezothutho) nakwiindawo ezikude ezinomthamo omncinci wegridi. Zibonelela ngamava alula ukuyisebenzisa ngeeseshoni zokutshaja zeyure e-1-3, iintlawulo eziphantsi, kunye nokuthembeka okuphezulu. Iitshaja ezinamandla aphezulu, nangona zikhawuleza, zingcono xa kujongwa izinto ezingxamisekileyo kodwa ziza neendleko eziphezulu.
Ngokwendalo, iitshaja zeDC ezincinci zihambelana nemigaqo-nkqubo yamandla asezidolophini, zinongcoliseko oluphantsi lwe-harmonic, kwaye zidibana neenkqubo zelanga/zokugcina. Iitshaja ezinamandla aphezulu zihlala zifuna iimvume zoshishino kwaye zinokuxinanisa iigridi zasekuhlaleni.
Ngamafutshane, iitshaja zeDC ezincinci zingabizi kakhulu, ziguquguquka, kwaye zizinzile, nto leyo ezenza zilungele ukusetyenziswa ezidolophini nakwezorhwebo, ngelixa ii-DC ezinamandla aphezuluiitshaja zeemoto zombanezihlala zibalulekile kwiimeko zezithuthi ezinabantu abaninzi kunye neemeko zomgama omde.
