The invention discloses a monitoring method and system for a battery system and a rail transit vehicle, and the method comprises the steps: enabling a second slave control module to collect the temperature and voltage of a battery module if the communication between a first slave control module and a master control module is abnormal; when the collected second temperature is greater than or equal to the first preset temperature and the collected second voltage is greater than or equal to the first preset voltage, an abnormal alarm signal is sent to the main control module, so that the main control module drives the contactor to be disconnected to implement safety protection when receiving the abnormal alarm signal; if the main control module fails and cannot drive the contactor to perform safety protection, the second slave control module can directly drive the contactor to be disconnected to perform safety protection when the collected second temperature is greater than or equal to the first preset temperature and the collected second voltage is greater than or equal to the first preset voltage. Therefore, the safety risk of the rail transit vehicle can be effectively reduced.
本申请公开了一种电池系统的监测方法、系统及轨道交通车辆,若出现第一从控模块和主控模块之间通信异常的情况,第二从控模块可以采集电池模组的温度和电压,并在采集到的第二温度大于等于第一预设温度且采集到的第二电压大于等于第一预设电压时,发送异常报警信号至主控模块,使得主控模块在接收到异常报警信号时,驱动接触器断开实施安全保护,若出现主控模块故障无法驱动接触器进行安全保护的情况,第二从控模块可以在采集到的第二温度大于等于第一预设温度且采集到的第二电压大于等于第一预设电压时,直接驱动接触器断开实施安全保护,从而能够有效地降低轨道交通车辆的安全风险。
