The invention provides a vehicle lithium battery charging method and device and electronic equipment, and the method comprises the steps: responding to a charging signal transmitted by a vehicle electronic control unit, issuing a closing instruction to a charging relay to enter a charging mode, and in a first charging stage after the starting time of the charging mode, starting the charging relay; whether the lithium battery has an overcurrent fault or not is judged based on a first current threshold value, the lithium battery is charged with first charging current in a first charging stage, and whether the lithium battery has the overcurrent fault or not is judged based on a second current threshold value in a second charging stage from the end of the first charging stage to the maximum charging total voltage of the lithium battery, the lithium battery is charged with a second charging current in a second charging stage, and whether the lithium battery has an overcurrent fault or not is judged on the basis of a third current threshold value in a third charging stage from the end of the second charging stage to the moment that the lithium battery reaches the highest voltage of the single battery, and the lithium battery is charged with a third charging current in the third charging stage; and the safety of the battery can be ensured.

    本公开提出一种车辆锂电池充电方法、装置及电子设备,方法包括:响应于车辆电子控制单元发送的充电信号,向充电继电器下发闭合指令以进入充电模式,并在充电模式开始时间后的第一充电阶段,基于第一电流阈值判断锂电池是否发生过流故障,其中,锂电池在第一充电阶段以第一充电电流充电,并在第一充电阶段结束至锂电池达到最高充电总压的第二充电阶段,基于第二电流阈值判断锂电池是否发生过流故障,其中,锂电池在第二充电阶段以第二充电电流充电,并在第二充电阶段结束至锂电池达到单体最高电压的第三充电阶段,基于第三电流阈值判断锂电池是否发生过流故障,其中,锂电池在第三充电阶段以第三充电电流充电,能够保证电池的安全性。
