The invention discloses an electric vehicle battery charging method which comprises the following steps: in response to a charging instruction, acquiring current vehicle information, detecting the starting state of a heater, and if the starting state of the heater is open, acquiring a standard charging ampere meter comprising a plurality of interval groups and a safety current coefficient table, determining a safe charging current according to the current vehicle information, the standard charging ammeter and the safe current coefficient table, and finally charging the battery by using the safe charging current. According to the invention, on the premise that the safety of the battery is ensured, the battery can be charged at the maximum power when APTC heating is started, APTC heating at all gears can be met, the situation that charging is slow and even charging power failure occurs under the condition of extremely low temperature of a client is avoided, meanwhile, other devices do not need to be added, and the cost is saved.

    本申请公开了一种电动车电池充电方法,响应于充电指令,通过获取当前车辆信息,并检测加热器开启状态,若加热器开启状态为打开,则获取包括多个区间组的标准充电电流表和安全电流系数表,并根据当前车辆信息、标准充电电流表和安全电流系数表确定安全充电电流,最后采用安全充电电流对电池进行充电。可以在保证电池安全的前提下,在开启APTC加热时对电池进行最大功率的充电,还可以满足全档位的APTC加热,避免了客户极低温度情况下充电慢甚至发生充电掉电的情况,同时不需要增加其他器件,节省了成本。
