An electric vehicle battery system includes a battery pack including battery cells housed within a housing, and a thermal runaway detection system including a sensor unit to send data and a control unit to receive data therefrom, the sensor unit being positioned within the battery pack and including a first cover element and a second cover element, the second cover element is arranged on/connected to the first cover element to form a space therebetween, the light emitter and the light sensor being arranged within the space such that light emitted from the light emitter can be received at the light sensor via a light path extending across the space, and the first cover element is designed to bend towards the second cover element and into the light path if the pressure in the battery pack increases, the control unit being configured to detect a thermal runaway based on a change in the transmitted data.
一种电动车辆电池系统包括电池组和热失控检测系统,电池组包括容纳在壳体内的电池单体,热失控检测系统包括发送数据的传感器单元和从其接收数据的控制单元,传感器单元定位在电池组内并且包括第一盖元件和第二盖元件,第二盖元件布置在第一盖元件上/连接到第一盖元件以在其间形成空间,光发射器和光传感器布置在空间内,使得从光发射器发射的光能够经由跨空间延伸的光路径在光传感器处被接收,并且第一盖元件被设计为如果电池组中的压力增加则朝向第二盖元件弯曲并进入光路径,控制单元被配置为基于所发送的数据的改变来检测热失控。
