The invention belongs to the technical field of battery management systems, and particularly relates to a BMS slave control address allocation method, a BMS master control module and a BMS slave control module. The BMS slave control address allocation method comprises the steps that a BMS master control module sends a periodic signal and a custom address signal to a first BMS slave control module at the same time; after a first BMS slave control module receives a first level abrupt change moment of the periodic signals, values of self-defined address signals at the level abrupt change moments of the set number of the periodic signals are continuously read to serve as addresses of the corresponding slave control modules; and after the address of the first BMS slave control module is set, processing the custom address signal to obtain the address of the next slave control module, and sending the periodic signal and the processed custom address signal to the next BMS slave control module. Through the address allocation method, the situation that when only the address signal is sent, the error of signal sending and receiving influences address setting is avoided, and the accuracy of setting the slave control address is improved.
本发明属于电池管理系统技术领域,具体涉及一种BMS从控地址分配方法及BMS主控模块、BMS从控模块。BMS从控地址分配方法包括:BMS主控模块同时发送周期性信号与自定义地址信号至第一个BMS从控模块;当第一个BMS从控模块接收到周期性信号的第一个电平突变时刻后,连续读取设定个数的周期性信号电平突变时刻处的自定义地址信号的值作为对应从控模块的地址;第一个BMS从控模块地址设置完毕后,对自定义地址信号进行处理以得到设置下一个从控模块的地址,将周期性信号和处理后的自定义地址信号发送给下一个BMS从控模块。通过上述地址分配方法,避免了因仅发送地址信号时,发送与接收信号的误差影响地址的设置,提高了设置从控地址的准确性。
