–Ukuba ufuna ukutshaja imoto yakho yombane ngokukhawuleza, awunakuphazama ngeteknoloji enamandla aphezulu ombane, enamandla okutshaja iipali.

Itekhnoloji yamandla aphezulu kunye ne-voltage ephezulu

Njengoko uluhlu lukhula kancinci kancinci, kukho imingeni efana nokunciphisa ixesha lokutshaja kunye nokunciphisa iindleko zobunini, kwaye umsebenzi wokuqala kukuphucula ubungakanani bemodyuli ukuze kufezekiswe ukuphuculwa kwamandla. Ekubeni amandla einqwaba yokutshajaNgokuyintloko kuxhomekeke ekubekweni kwamandla kwimodyuli yokutshaja, kwaye kunqunyelwe bubungakanani bemveliso, indawo yomgangatho kunye neendleko zokuvelisa, ukunyusa nje inani leemodyuli akusesona sisombululo silungileyo. Ke ngoko, indlela yokunyusa amandla emodyuli enye ngaphandle kokongeza ivolumu eyongezelelweyo ibe yingxaki yobuchwepheshe ebangela ukubaabavelisi bemodyuli yokutshajakufuneka boyise ngokukhawuleza.

Izixhobo zokutshaja zeDCifikelela kubuchule bokutshaja ngokukhawuleza obugqwesileyo ngokusebenzisa iteknoloji yamandla aphezulu kunye ne-voltage ephezulu. Ngokunyuka kancinci kwe-voltage kunye namandla, oku kubeka phambili iimfuno ezingqongqo zokusebenza okuzinzileyo, ukuchithwa kobushushu okusebenzayo kunye nokusebenza kakuhle kokuguqulwa kwemodyuli yokutshaja, ngokungathandabuzekiyo okubeka imingeni ephezulu yobugcisa kubavelisi beemodyuli zokutshaja.

Ngenxa yemfuno yemarike yokutshaja ngokukhawuleza ngamandla aphezulu, abavelisi beemodyuli zokutshaja kufuneka baqhubeke nokuvelisa nokuphucula iteknoloji esisiseko kwaye bakhe imiqobo yabo yobugcisa engundoqo. Oku kuya kuba sisitshixo sokhuphiswano lwemarike lwexesha elizayo, kuphela ngokuqonda iteknoloji eyintloko, ukuze bangoyiswa kukhuphiswano olukhulu lwemarike.

1) Indlela yombane ophezulu: inqanaba lokunyusa liphantsi, kwaye iimfuno zolawulo lobushushu ziphezulu. Ngokomthetho kaJoule (ifomyula Q=I2Rt), ukunyuka kombane kuya kwandisa kakhulu ubushushu ngexesha lokutshaja, okuneemfuno eziphezulu zokusasaza ubushushu, njengesisombululo sokutshaja esikhawulezayo sikaTesla, esine-V3 supercharging pile enombane osebenzayo ophezulu ongaphezulu kwe-600A, ofuna i-wiring harness etyebileyo, kwaye kwangaxeshanye, ineemfuno eziphezulu zobuchwepheshe bokusasaza ubushushu, kwaye inokufikelela kuphela kumandla aphezulu okutshaja angama-250kW kwi-5%-27% SOC, kwaye ukutshaja okusebenzayo akugutyungelwanga ngokupheleleyo. Okwangoku, abavelisi beemoto zasekhaya abakenzanga utshintsho olubalulekileyo olucwangcisiweyo kwiskimu sokusasaza ubushushu, kwayeiinqwaba zokutshaja ezinombane ophezulubathembele kakhulu kwiinkqubo ezakhelwe zona, nto leyo ebangela iindleko eziphezulu zokunyusa umgangatho.

2) Indlela ye-high-voltage: Yindlela esetyenziswa rhoqo ngabavelisi beemoto, enokuqwalasela iingenelo zokunciphisa ukusetyenziswa kwamandla, ukuphucula ubomi bebhetri, ukunciphisa ubunzima, kunye nokonga indawo. Okwangoku, ithintelwe ngumthamo we-stander voltage wezixhobo zamandla ze-IGBT ezisekwe kwi-silicon, isisombululo sokutshaja ngokukhawuleza esamkelwa rhoqo ziinkampani zeemoto yiplatifomu ye-400V high-voltage, oko kukuthi, amandla okutshaja e-100kW anokufezekiswa ngombane we-250A (amandla e-100kW angatshajwa imizuzu eli-10 malunga ne-100km). Ukususela oko kwaqaliswa iplatifomu ye-800V ephezulu ye-Porsche (efikelela kumandla e-300KW kwaye inciphise i-high-voltage wiring harness ngesiqingatha), iinkampani ezinkulu zeemoto ziqale ukuphanda kunye nokubeka iplatifomu ye-800V ephezulu. Xa kuthelekiswa neplatifomu ye-400V, iplatifomu ye-800V voltage inombane omncinci osebenzayo, ogcina umthamo we-wiring harness, unciphisa ukulahleka kokumelana kwangaphakathi kwesekethe, kwaye uphucula uxinano lwamandla kunye nokusebenza kakuhle kwamandla kwi-hisset.

Okwangoku, uluhlu lwamandla aphuma rhoqo kwimodyuli ephambili ye-40kW kushishino yi-300Vdc ~ 1000Vdc, ehambelana neemfuno zokutshaja zeemoto zabakhweli zeqonga langoku le-400V, iibhasi ze-750V kunye nezithuthi zeqonga lamandla aphezulu ze-800V-1000V ezizayo; Uluhlu lwamandla aphumayo kwimodyuli ye-40kW ye-Infineon, iTelai kunye neShenghong lunokufikelela kwi-50Vdc ~ 1000Vdc, kuthathelwa ingqalelo iimfuno zokutshaja zezithuthi ze-low voltage. Ngokuphathelele ukusebenza kakuhle kwemodyuli iyonke, iimodyuli ze-40kW ezisebenzayo kakhulu zeBeiHai AmandlaSebenzisa izixhobo zamandla ze-SIC, kwaye ukusebenza kakuhle okuphezulu kunokufikelela kwi-97%, okungaphezulu komndilili weshishini.
