NgoNovemba ka-2022, ukuthengiswa kwezithuthi zombane kwihlabathi kuqhubekile ukonyuka ngenani eliphindwe kabini unyaka nonyaka (46%), kunye nokuthengiswa kwezithuthi zombane kubalelwa kwi-18% yentengiso yeemoto zehlabathi jikelele, kunye nesabelo sentengiso yezithuthi zombane ezisulungekileyo ezikhula ukuya kutsho. 13%.
Akukho mathandabuzo okuba ukufakelwa kombane sele kulisikhokelo sophuhliso lweshishini leemoto kwihlabathi.Kwimeko yehlabathi yokukhula okuqhushumbayo kwezithuthi zamandla amatsha, izixhobo ezidityanisiweyo zeebhokisi zebhetri yemoto zombane nazo zingenise amathuba amakhulu ophuhliso, kwaye iinkampani ezinkulu zeemoto zikwabeke phambili iimfuno eziphezulu zetekhnoloji kunye nokusebenza kwezixhobo ezidibeneyo zebhetri yemoto yombane. iibhokisi.
Amagumbi ombane we-high-voltage yeenkqubo zebhetri yemoto kufuneka ulungelelanise inani leemfuno ezinzima.Okokuqala, kufuneka babonelele ngeempawu zexesha elide lomatshini, kubandakanywa ukuqina kwe-torsional kunye ne-flexural, ukuthwala iiseli ezinzima phezu kobomi bepakethe ngelixa bebakhusela kwi-corrosion, impembelelo yamatye, uthuli kunye nokungena komswakama, kunye nokuvuza kwe-electrolyte.Kwezinye iimeko, imeko yebhetri nayo kufuneka ikwazi ukukhusela ukukhutshwa kwe-electrostatic kunye ne-EMI/RFI kwiinkqubo ezikufutshane.
Okwesibini, xa kwenzeka ingozi, ityala kufuneka likhusele inkqubo yebhetri ekuqhekekeni, ukubhobhoza, okanye ukujikeleza okufutshane ngenxa yokungena kwamanzi / umswakama.Okwesithathu, inkqubo yebhetri ye-EV kufuneka incede ukugcina iseli nganye ngaphakathi koluhlu olufunekayo lwe-thermal ngexesha lokutshaja / ukukhupha kuzo zonke iintlobo zemozulu.Xa kwenzeka umlilo, kufuneka baphinde bagcine ipakethi yebhetri ingadibanisi namadangatye ixesha elide kunokwenzeka, ngelixa bekhusela abahlali bezithuthi ekushiseni kunye nomlilo owenziwe yi-thermal runaway ngaphakathi kwebhetri.Kukho nemingeni efana nefuthe lobunzima kuluhlu lokuqhuba, impembelelo yokunyamezela ukupakishwa kweeseli kwindawo yokufakela, iindleko zokuvelisa, ukugcinwa kunye nokuphela kobomi bokubuyisela kwakhona.
