The invention provides a device and method for charging a starting power supply of an electric vehicle. The device comprises a vehicle socket CLCZ, a power storage battery DL, a DC-to-DC module DC/DC, an intelligent battery sensor IBS, a starting storage battery XD, a battery management module BMS and a starting power supply charging relay K1. When the battery management module BMS detects that the electric quantity of the starting storage battery XD is insufficient through the intelligent battery sensor IBS, the starting storage battery charging relay K1 is switched on to charge the starting storage battery XD. The charging device has the advantages that when the electric automobile is charged fast and slowly, the starting storage battery can be effectively charged, the situation that the automobile is in danger due to the fact that the starting storage battery is lack of electricity is prevented, the overall structure is simple, and reliability is high.

    本发明提出一种电动汽车启动电源补电的装置和方法,包括车辆插座CLCZ、动力蓄电池DL、DC转DC模块DC/DC、智能电池传感器IBS、启动蓄电池XD、电池管理模块BMS和启动电源补电继电器K1;电池管理模块BMS通过智能电池传感器IBS检测启动蓄电池XD的电量不足时,接通启动蓄电池补电继电器K1给启动蓄电池XD补电。本发明有益效果为:可以在电动汽车进行快慢充时,有效的给启动蓄电池补电,防止启动蓄电池亏电造成车辆发生危险,整体结构简洁,可靠性高。
