示例性的，低压接口可以与整车控制器相连接，整车控制器通过低压接口PL向高压互锁回路中输出低电平信号，若互锁插口处出现断路现象，整车控制器无法接收到输出的低电平信号，则整车控制器可以通过低压接口向控制器U1输出互锁异常状态，控制器U1执行设定的安全控制策略。
作为一种可选方案，本实施例中，配电盒采用金属壳体，通过配置金属壳体可以保证高压配电盒的电磁兼容性能。
作为一种可实施方案，配电盒还配置有透气阀。示例性的，透气阀基于气体分子与液体、灰尘颗粒存在的体积的差值，可以允许气体通过，液体、灰尘 无法通过，从而使配电盒具备防水透气的能力，通过配置透气阀可以保证配电盒内外压力的平衡。
图2所示配电盒的内部配置正充电继电器、负充电继电器，相对于将充电继电器配置在配电盒外部，可以减小充电线束的长度，降低充电线束的线径。此外，配电盒内部划分为高压配线区和低压配线区，使得配电盒内部高压部分与低压部分具备一定的电气间隙和爬电距离，保证高压部分与低压部分、金属壳体之间的绝缘性能和耐压性能。
图2所示配电盒的内部配置有电压采样点、温度采样点以及电流采样点，配电盒内部的控制器可以实现充电电压、充电电流以及温度的监测，便于在充电桩或整车出现问题无法停止充电流程时，通过配电盒可以自主的切断高压用电回路，保证人员及整车的用电安全。
