The disclosure provides thermal event mitigation for battery packs. This disclosure relates to thermal event mitigation for battery packs of electrified vehicles. An example electrified vehicle includes a battery assembly with an enclosure assembly surrounding at least one battery array and a bag configured to selectively release nitrogen. The electrified vehicle further includes a controller configured to issue a plurality of corrective action commands in response to a detected thermal event. One of the corrective action commands includes instructing the bag to generate and release nitrogen within the enclosure assembly. Among other benefits, which will be appreciated from the below description, the disclosed arrangement promptly mitigates a thermal event of the battery assembly and takes additional corrective actions, such as providing various prompts and status indicators to the user.

    本公开提供“用于电池组的热事件缓解”。本公开涉及用于电动化车辆的电池组的热事件缓解。一种示例性电动化车辆包括电池总成,所述电池总成具有围绕至少一个电池阵列的外壳总成和被配置为选择性地释放氮气的袋。所述电动化车辆还包括控制器,所述控制器被配置为响应于检测到的热事件而发出多个纠正动作命令。所述纠正动作命令中的一个包括指示所述袋在所述外壳总成内产生和释放氮气。除了将从以下描述中理解的其他益处之外,所公开的布置迅速地缓解了电池总成的热事件并采取了附加的纠正动作,诸如向用户提供各种提示和状态指示器。
