The invention relates to an electric tricycle battery heating method which comprises the following steps: S1, detecting the temperature of a battery, and if the temperature of the battery is normal, normally charging the battery by a charger; if the temperature of the battery is low, carrying out the next step; s2, detecting the remaining capacity of the battery, and performing corresponding operation according to different conditions of the remaining capacity of the battery until the temperature of the battery reaches a preset value; and S3, the charger normally charges the battery. According to the invention, hardware cost is not increased, and the temperature of the battery can be rapidly raised by only using a charger and combining a motor and electric control on the whole vehicle; when the temperature of the battery is increased to a proper temperature, the charger can directly charge the battery at a relatively high rate, so that the charging power is not limited due to low temperature, and even the battery cannot be charged, and the charging time can be greatly shortened; in a low-temperature environment, the battery capacity loss is large, so that the battery capacity in the low-temperature environment can be greatly improved, and the endurance mileage during traveling is ensured.

    本发明涉及一种电动二三轮车电池加热方法,包括以下步骤,S1、检测电池温度,若电池温度正常,则充电器对电池正常充电;若电池温度偏低,则进行下一步骤;S2、检测电池剩余电量,根据电池剩余电量的不同情况进行对应操作直到电池温度达到预设值;S3、充电器对电池进行正常充电。本发明不增加硬件成本,仅使用充电器,结合整车上的电机和电控即可快速的使电池温度上升;当电池温度提升到合适温度后,充电器可直接以较大倍率进行充电,不必再因为温度低而限制充电功率,甚至无法充电,可以大幅减少充电时间;在低温环境中,电池容量损失大,本发明可以大幅提升低温环境下的电池容量,保证出行时的续航里程。
