The invention relates to an electric automobile storage battery charging method, in particular to an intelligent charging method for an automobile starting power source. The intelligent charging method comprises the following steps: (1) detecting and judging the voltage of a 12V storage battery; (2) charging the 12V storage battery by the DCDC; and (3) reminding and re-timing after intelligent charging is finished. Compared with the prior art, the method has the beneficial effects that (1) the requirement of the static days of the whole vehicle on the capacity of the storage battery is reduced, the capacity of the storage battery can be reduced, and the method plays a positive role in the cost and weight target of the whole vehicle; (2) the voltage value is used as an intelligent charging judgment condition, so that the development work of the storage battery sensor is reduced, the development period is shortened, and the development cost is reduced; and (3) when the quiescent current is too large due to the fault of the whole vehicle, the power shortage risk of the 12V storage battery is reduced, and the influence of the use of the vehicle by customers is reduced.

    本发明涉及电动汽车蓄电池充电方法,具体为一种汽车启动电源的智能补电方法。一种汽车启动电源的智能补电方法,包括如下步骤:(1)12V蓄电池电压的检测和判断条件;(2)DCDC对12V蓄电池补电的过程;(3)智能补电结束后提醒及重新计时。与现有技术相比具有的有益效果:(1)减小了整车静态天数对蓄电池容量的需求,可降低蓄电池容量,对整车成本和重量目标有积极的作用。(2)将电压值作为智能补电判断条件,减少了对蓄电池传感器的开发工作,降低开发周期和开发成本。(3)当整车由于故障,导致静态电流过大时,降低12V蓄电池发生亏电风险,减小客户对车辆使用的影响。
