A battery system includes a rechargeable energy storage system (RESS) having battery cells, and a battery controller network configured to execute two-level logic to detect a thermal runaway condition. The network includes RES S-embedded cell monitoring units (CMUs) electrically connected to a respective cell group, and measuring and wirelessly transmitting cell data. A battery control module (BCM) is in communication with the CMUs. Thermal runaway sensors are mounted on the CMUs and/or the BCM. A master controller connected to the BCM includes a thermal runaway detection algorithm configured to detect a thermal runaway condition occurring within the RESS. The BCM uses data from the CMUs and thermal runaway sensors to execute first logic level which determines when to wake up the master controller. The master controller, in response to receipt of a wakeup signal, executes a second logic level to execute the algorithm.

    一种蓄电池系统包括具有蓄电池单元的可再充电能量存储系统(RESS),以及被配置成执行两级逻辑以检测热散逸状况的蓄电池控制器网络。所述网络包括RESS嵌入式电池监测单元(CMU),所述RESS嵌入式电池监测单元(CMU)电连接到相应电池群组,并且测量和无线地发送电池数据。蓄电池控制模块(BCM)与所述CMU通信。热散逸传感器安装在所述CMU和/或所述BCM上。连接到所述BCM的主控制器包括被配置成检测在所述RESS内发生的热散逸状况的热散逸检测算法。所述BCM使用来自所述CMU和热散逸传感器的数据来执行确定何时唤醒所述主控制器的第一逻辑级。所述主控制器响应于接收到唤醒信号而执行第二逻辑级以执行所述算法。
