The invention discloses an industrial vehicle lithium battery charging control method and system, and the method comprises the steps: detecting a PP hardware connection signal of a charging seat through a BMS, and determining the hardware standard of the charging seat according to the PP hardware connection signal; determining a corresponding PP signal resistance value according to the PP hardware connection signal, determining the type of the charging seat according to the PP signal resistance value, and judging whether the corresponding PP signal resistance value is correct or not according to the hardware standard of the charging seat; when the PP signal resistance value is judged to be correct, a communication protocol corresponding to the type of the charging seat is converted into a national standard communication protocol through EVCC, and the BMS performs a national standard charging communication process according to the national standard communication protocol; pP hardware connection signals of different standard charging seats are respectively detected through the detection ports, so that the time delay in the EVCC simulation signal forwarding process is reduced, the program complexity and cost caused by different specifications of different standard EVCC are reduced, and the fault points of the EVCC are reduced; european standard and American standard compatibility is realized by the EVCC through a charging logic and a communication protocol, and replacement and use of the EVCC are realized.

    本发明公开了一种工业车辆锂电池充电控制方法及系统,包括:通过BMS检测充电座的PP硬件连接信号,根据PP硬件连接信号确定充电座硬件标准;根据PP硬件连接信号确定对应的PP信号阻值,根据PP信号阻值确定充电座的类型,根据充电座硬件标准判断对应的PP信号阻值是否正确;当所述的PP信号阻值判断正确时,通过EVCC转换充电座的类型对应的通讯协议为国标通讯协议,BMS根据国标通讯协议进行国标充电通讯流程;过检测口分别检测不同标准充电座的PP硬件连接信号,减少了EVCC模拟转发信号过程中的延时,降低了不同标准EVCC规格不同带来的程序复杂性和成本,减少了EVCC的故障点;让EVCC用一种充电逻辑和通讯协议做到欧标美标的兼容,实现EVCC在的替换使用。
