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 ethintela ukuba zifikelele 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 zihlala ixesha elide, nto leyo ezenza zilungele ukusetyenziswa ezidolophini nakwezorhwebo, ngelixa iitshaja zeDC ezinamandla aphezuluiitshaja zeemoto zombanezihlala zibalulekile kwiimeko zezithuthi ezinabantu abaninzi kunye neemeko zomgama omde.
