The invention discloses an electric vehicle safety charging method and electronic equipment. The method comprises the following steps: controlling a charger to charge a battery pack of an electric vehicle by adopting required voltage, gradually increasing charging current until the charging current reaches a preset required current upper limit value, and then conducting constant-current charging until the highest individual voltage in the battery pack reaches a preset cut-off voltage value; and conducting constant-voltage charging, gradually reducing the charging current, and stopping charginguntil the charging current is reduced to a preset cut-off current value. According to the invention, by using the highest individual voltage as a main reference index, the required current value is adjusted, the required current is flexibly controlled in a constant-current mode, and adjustment is carried out according to feedback of the actual output current, so that the method can adapt to cellswith different aging degrees in the battery pack, and overcharge is avoided.

    本发明公开一种电动汽车安全充电方法及电子设备,方法包括:控制充电机采用需求电压向电动汽车的电池组充电,逐渐增加充电电流,直到充电电流达到预设需求电流上限值,采用恒流充电,直到电池组中最高的单体电压达到预设截止电压值;采用恒压充电,逐渐减少充电电流,直到充电电流减少到预设截止电流值,则停止充电。本发明以最高单体电压为主要参考指标,调整需求电流值,使用恒流模式,柔性的控制需求电流,并根据实际输出电流的反馈进行调整,从而使得能够适应电池组中老化程度不同的电芯,避免过充。
