The invention relates to the field of battery charging methods, in particular to a new energy automobile battery pack temperature control method. A new energy automobile battery pack temperature control method comprises the steps of obtaining a first temperature when a battery pack is charged and an optimal charging temperature of the battery pack, and connecting the battery pack with a charging device; when the first temperature is the same as the optimal charging temperature, charging with the maximum current; when the first temperature is different from the optimal charging temperature, the first temperature is adjusted to the optimal charging temperature, and then charging is carried out with the maximum current; a second temperature of the battery is obtained after the battery pack is charged with the maximum current for a first preset time; and when the second temperature is greater than the optimal charging temperature, cooling the battery pack, and further continuously charging the battery pack with the maximum current. And when the second temperature during charging of the battery pack is greater than the optimal charging temperature, the battery pack is cooled, so that the charging efficiency of the battery pack is ensured and the battery pack is protected.

    本发明涉及电池充电方法领域,具体涉及一种新能源汽车电池组温度控制方法。一种新能源汽车电池组温度控制方法,获取电池组充电时的第一温度和电池组最适充电温度,并将电池组连接充电装置;第一温度与最适充电温度相同时,以最大电流充电;第一温度与最适充电温度不同时,对第一温度进行调节至最适充电温度,进而以最大电流进行充电;以最大电流对电池组充电第一预设时间后获取电池的第二温度;第二温度大于最适充电温度时,对电池组进行降温处理,进而继续以最大电流对电池组进行充电。当电池组充电时的第二温度大于最适充电温度时,对电池组进行降温处理,从而保证电池组的充电效率和保护电池组的作用。
