摘要： 文章针对电动汽车充电插座温度监控方案开展研究，电动汽车执行的是传导式充电， 可能存在过温、烧蚀、过热等由焦耳热引起的温升问题。为了防止过温而导致车辆安全问题， 需对温度传感器的不同布置位置的温度精度和响应速度进行验证和分析。通过验证分析发现， 温度传感器布置位置对响应灵敏度有明显影响，距离热源越近的位置，其精度越高、响应滞 后性越小，将温度传感器布置在接触件内部时可以满足[-4 K, 0]的精度。

Abstract: This paper investigates temperature monitoring schemes for electric vehicle charging sockets. Electric vehicles utilize conductive charging, which may cause temperature rise issues such as overheating, ablation, and over-temperature due to Joule heating. To prevent safety hazards caused by overheating, the accuracy and response speed of temperature sensors placed at different positions were verified and analyzed. Validation and analysis indicate that the placement of temperature sensors significantly affects response sensitivity. Positions closer to the heat source exhibit higher accuracy and lower response lag. Placing the temperature sensor inside the contact component meets an accuracy requirement of [-4 K, 0].
