• Tsav style: Tsav tsheb nrawm nrawm hnav.

• Battery Management System (BMS): Ib qho zoo BMS pab tswj lub neej ntev.

4. Tus nqi degradation

• EV roj teeb feem ntau poob txog1-2% ntawm lub peev xwm ib xyoos twg.

• Tom qab 8-10 xyoo, ntau tus tseem khaws cia70-80%ntawm lawv qhov peev xwm qub.

5. Lub Neej Thib Ob

• Thaum lub roj teeb EV tsis tuaj yeem siv lub tsheb ua haujlwm tau zoo, nws tseem tuaj yeem rov qab siv tau ntau zauszog cia systems(Tsev los yog daim phiaj siv).
