Abstract

本发明涉及充电枪技术领域，且公开了一种具备异物检测与主动防护功能的新能源车充电枪，包括手持枪体，以及设置在手持枪体一端接线主体，手持枪体远离接线主体的一端设置有充电接头，充电接头的内壁安装有异物检测终端，充电接头插入车辆充电口后，异物检测终端保持持续监测状态，红外阵列传感模块重点扫描接头与充电口的对接缝隙，防止充电过程中昆虫钻入、液体渗入或异物掉落，同心圆电容传感模块实时监测导电针脚的接触状态，电容值出现波动时，立即触发预警，双路超声波传感模块则辅助判断异物是否持续靠近，当检测到低风险异物，仅通过APP推送提醒，不中断充电，若检测到高风险异物，立即通过CANFD发送紧急断电指令。
