新能源电动汽车在开展碰撞试验后，存在两个时间阶段会出现起火的安全事件，第一个时间阶段是碰撞后5分钟内，存在立刻发送起火燃烧现象，第二个时间阶段是碰撞后5分钟-72小时，存在电池模组内部或线路出现短路等现象，导致温度缓慢升高从而发生起火燃烧。
After carrying out the crash test, there are two safety incidents in which a fire will occur in the new energy electric vehicle. The first stage is within five minutes after the collision, and there is the phenomenon of sending fire and burning immediately. The second stage is from 5 minutes to 72 hours after the collision. There is a short circuit inside the battery module or in the circuit, which causes the temperature to rise slowly and cause the fire to burn.
然而目前普遍是将车辆或者电池模组存放在一个区域，使用视频监控进行安全监视，如果一旦发生起火事件，工程师只能判断何时起火，无法准确的得到起火数据，如：起火源在什么位置，起火温度多少，温度变化曲线等数据信息，从而进行有效的分析和改进工作；
At present, however, it is common to store vehicles or battery modules in an area and use video surveillance for safety surveillance. If a fire occurs, the engineer can only judge when the fire broke out and cannot accurately obtain the fire data. Such as: where the origin of the fire, how much the fire temperature, temperature change curve and other data information, so as to carry out effective analysis and improvement work;
无线温度监控仪是针对第二个时间段所产生的安全风险所开发的温度实时监控和采集设备；
Wireless temperature monitor is a real-time temperature monitoring and acquisition device developed for the safety risk caused by the second time period.
