-Ukuba ufuna ukutshaja ngokukhawuleza kwimoto yakho yombane, awukwazi ukungahambi kakuhle nge-voltage ephezulu, itekhnoloji ephezulu yangoku yokutshaja iimfumba

Itekhnoloji ephezulu yangoku kunye nephezulu yombane

Njengoko uluhlu lukhula ngokuthe ngcembe, kukho imingeni efana nokunciphisa ixesha lokutshaja kunye nokunciphisa iindleko zobunini, kwaye umsebenzi wokuqala kukwandisa ubungakanani bemodyuli ukufezekisa ukuphuculwa kwamandla. Ukusukela amandla einqwaba yokutshajaubukhulu becala kuxhomekeke kumandla aphezulu emodyuli yokutshaja, kwaye inqunyelwe ngumthamo wemveliso, indawo yomgangatho kunye neendleko zokuvelisa, ukwandisa nje inani leemodyuli akusesona sisombululo silungileyo. Ke ngoko, indlela yokunyusa amandla emodyuli enye ngaphandle kokongeza ivolumu eyongezelelweyo ibe yingxaki yobugcisaabavelisi bemodyuli ababizayokufuneka boyise ngokukhawuleza.

Izixhobo zokutshaja ze-DCiphumeza isakhono sokutshaja esikhawulezileyo ngetekhnoloji yangoku kunye ne-high-voltage. Ngokunyuka ngokuthe ngcembe kwamandla ombane kunye namandla, oku kubeka phambili iimfuno ezingqongqo ngakumbi ekusebenzeni okuzinzile, ukuchithwa kobushushu okusebenzayo kunye nokuguqulwa kokusebenza kakuhle kwemodyuli yokutshaja, ngokungathandabuzekiyo ibeka imingeni ephezulu yobugcisa bokutshaja abavelisi bemodyuli.

Phambi kwemfuno yemarike yokutshaja okukhawulezileyo kwamandla, abavelisi beemodyuli zokutshaja kufuneka baqhubeke bevelisa izinto ezintsha kwaye baphucule itekhnoloji esisiseko kunye nokwakha eyabo imiqobo yobuchwephesha. Oku kuya kuba ngundoqo kukhuphiswano lweemarike zexesha elizayo, kuphela ngokulawula iteknoloji engundoqo, ukuze ungabikho kukhuphiswano lwemarike.

I-1) Indlela ephezulu yangoku: iqondo lokunyuswa liphantsi, kwaye iimfuno zolawulo lwe-thermal ziphezulu. Ngokomthetho kaJoule (ifomula Q = I2Rt), ukunyuka kwangoku kuya kwandisa kakhulu ubushushu ngexesha lokutshaja, elineemfuno eziphezulu zokutshatyalaliswa kobushushu, njengesisombululo se-Tesla esiphezulu sokutshaja ngokukhawuleza, i-V3 yayo i-supercharging pile ine-peak yokusebenza ngoku engaphezulu kwe-600A, efuna i-wiring enzima kwiimfuno ze-wiring ephezulu, kwaye i-dissipa ineemfuno eziphezulu ze-wiring ngexesha elifanayo, kwaye i-dissipa ineemfuno eziphezulu zokushisa, kwaye i-dissipa ikwazi ukufikelela kuphela kwi-warness ephezulu. Amandla okutshaja aphezulu angama-250kW kwi-5% -27% SOC, kwaye ukutshaja okusebenzayo akukhuselwanga ngokupheleleyo. Okwangoku, abavelisi beemoto zasekhaya abazange benze utshintsho olubalulekileyo olucwangcisiweyo kwiskimu sokutshatyalaliswa kobushushu, kunyeiimfumba zokutshaja zangoku eziphezuluukuthembela kakhulu kwiinkqubo zokuzakhela, ezikhokelela kwiindleko eziphezulu zokunyusa.

I-2) Umzila we-high-voltage: Yindlela esetyenziswa ngokuqhelekileyo ngabavelisi beemoto, ezinokuthathela ingqalelo inzuzo yokunciphisa ukusetyenziswa kwamandla, ukuphucula ubomi bebhetri, ukunciphisa ubunzima, kunye nokugcina indawo. Okwangoku, umda wokumelana nomthamo wombane wezixhobo zamandla ze-silicon-based IGBT, isisombululo sokutshaja ngokukhawuleza esiqhele ukwamkelwa ziinkampani zeemoto yi-400V iqonga le-voltage ephezulu, oko kukuthi, amandla okutshaja angama-100kW anokufezekiswa ngokusebenza kwe-250A (100kW amandla angahlawuliswa i-10km malunga ne-100km). Ukusukela oko kwaphehlelelwa iqonga lePorsche's 800V high-voltage (ukufikelela kumandla angama-300KW kunye nokunciphisa intambo yokubopha iingcingo ezinombane ophezulu ngesiqingatha), iinkampani ezinkulu zeemoto ziye zaqalisa ukuphanda nokucwangcisa iqonga le-800V levoltage ephezulu. Xa kuthelekiswa neqonga le-400V, iqonga le-voltage ye-800V linombane omncinci wokusebenza, ogcina umthamo we-wire harness, inciphisa ilahleko yangaphakathi yokumelana nesekethe, kwaye iphucula ukuxinana kwamandla kunye nokusebenza kakuhle kwamandla ekufihleni.

Okwangoku, uluhlu lwamandla ombane ophuma rhoqo kwimodyuli ye-40kW eqhelekileyo kwishishini yi-300Vdc ~ 1000Vdc, ehambelana neemfuno zokutshaja kweemoto zangoku ze-400V zeqonga lomkhweli, iibhasi ze-750V kunye ne-800V-1000V izithuthi zeqonga eliphezulu le-voltage yexesha elizayo; Uluhlu lombane oluphumayo lwemodyuli ye-40kW ye-Infineon, iTelai ne-Shenghong inokufikelela kwi-50Vdc ~ 1000Vdc, ngokuqwalasela iimfuno zokutshaja kwezithuthi eziphantsi kwe-voltage. Ngokumalunga nokusebenza kakuhle kwemodyuli iyonke, iimodyuli ze-40kW ezisebenza kakuhle kakhuluBeiHai Amandlasebenzisa izixhobo zamandla ze-SIC, kunye nokusebenza kakuhle okuphezulu kunokufikelela kwi-97%, ephezulu kunomndilili woshishino.
