Can a New Energy Vehicle Charge the Auxiliary Battery While Idling?

[MacLilliana]

New energy vehicles can charge the auxiliary battery while idling. When the auxiliary battery is depleted, even if the high-voltage battery pack has sufficient charge, the new energy vehicle will fail to start. Additionally, using electrical devices within the vehicle while it is stationary can lead to the auxiliary battery losing its charge. Methods to charge the auxiliary battery: If the auxiliary battery is completely drained, the only solution is to remove it, charge it fully using a charger, and then reinstall it in the vehicle. If the new energy vehicle can still start, driving it for several dozen kilometers will allow the high-voltage battery pack to recharge the auxiliary battery during this period. Charging precautions: It is important to note that if the auxiliary battery is dead, one must never attempt to jump-start it using the high-voltage battery pack in the new energy vehicle. This is due to the presence of high-voltage electricity, and improper handling by non-professionals could pose a risk of electric shock.
