A system for mitigating thermal runaway in a battery powered electric vehicle (EV). The system includes: a gas sensor configured to measure a level of at least one type of gas near a battery of the EV; a thermal event detector configured to determine that the battery is experiencing deflation based on a measured level of the at least one type of gas; and a communication interface configured to transmit an alert regarding battery deflation to the queue management system. The queue management system alters the assignment of the EV in response to battery deflation. 一种用于缓解电池供电的电动交通工具（EV）中的热失控的系统。所述系统包括：气体传感器，被配置为测量EV的电池附近的至少一种类型气体的水平；热事件检测器，被配置为基于所述至少一种类型气体的测量水平来确定电池正在经历放气；以及通信接口，被配置为向队列管理系统传输关于电池放气的警告。队列管理系统响应于电池放气而更改EV的指派。
