The invention provides a sodium-lithium battery car and a charging control method. According to the sodium-lithium battery car, sodium-lithium hybrid batteries are designed to be arranged in a crossed mode, a voltage and current adjusting array is arranged, and internal and external temperatures of the batteries are considered; constructing a charging characteristic map for charging strategy control, and considering the characteristics of each battery cell string to control the charging of the battery car so as to prevent spontaneous combustion caused by too fast and too high temperature rise of the battery during charging; and meanwhile, when the user does not use the battery car for a long time, the battery of the battery car is controlled to be repeatedly charged and naturally discharged between 20% and 90% of electric quantity, so that the battery of the battery car cannot be damaged due to insufficient electricity and cannot be lost due to the fact that the cycle index is reduced due to repeated charging, and convenience is also provided for the user.

    本发明提供了一种钠锂电瓶车及充电控制方法,所述钠锂电瓶车通过将钠锂混合电池设计为十字交叉排布、设置电压电流调整阵列、考虑电池内外部温度、构建用于充电策略控制的充电特性地图考虑每个电芯串的特性来控制电瓶车充电以防止充电时电池温度升温过快过高而自燃的情况;同时在用户长时间不使用电瓶车时,通过控制电瓶车电池在20%和90%电量之间反复的充电和自然放电,保证了电瓶车电池既不会因为电池亏电损坏也不会因为反复充电降低循环次数而损耗,也给用户提供了方便。
