摘要： 文章针对新能源汽车动力电池系统在教学演示与原理验证中存在监测量分散、异常工 况难以可控复现，以及保护联锁过程不直观等问题，研制了一套动力电池安全监测与联锁保 护实验装置。装置以不锈钢箱体模拟电池箱体，在六个面布置 6 路温度传感器，并在侧面集 成薄膜压力传感器以模拟鼓包/挤压异常；输出端可外接负载，通过电流传感器实现放电电流 监测。系统以 Mega 2560 主控板为核心，配套 11.43 cm（4.5 英寸）触摸屏实现参数显示与阈 值设定，上电完成自检；当温度、压力或电流超限时触发语音报警并驱动继电器切断输出， 实现故障锁定。温度超限、压力阶跃与过流试验表明，装置动作稳定、响应一致，可为动力 电池安全机理教学与保护策略验证提供支撑。

Abstract: This paper develops an experimental device for safety monitoring and interlock protection of a power battery system. A stainless-steel box is used to simulate a battery enclosure. Six temperature sensors are mounted on the six faces, and a film pressure sensor is installed on the side to emulate swelling or external compression. An external load can be connected to the output port, and the discharge current is monitored by a current sensor. A Mega 2560 controller with a 11.43 cm (4.5-inch) touch screen provides real-time display, threshold setting, and power-on self-check. When over-temperature, abnormal pressure, or over-current is detected, the device triggers a voice alarm and disconnects the output through a relay with fault latching. Tests on over-temperature, pressure step, and over-current confirm stable triggering and consistent protection actions. The device provides practical support for mechanism demonstration and protection strategy verification of traction battery safety.
