The invention discloses a charging gun with a voltage measuring function and a charging pile, and the charging gun comprises a gun body, a handheld part, a starting assembly, a charging head and a small plate, the charging head is internally provided with a charging electrode which is electrically connected with a charging wire, and the other end of the charging wire is electrically connected with an input terminal on the small plate. An input end common mode inductor, an electric quantity metering chip, a common mode inductor, a first X capacitor, a current transformer, a relay and an output end are arranged on the small plate, and a power supply output end is arranged on the small plate. According to the utility model, a signal can be transmitted to the miniature relay when charging is completed, and circuit connection is cut off through control of the miniature relay, so that the phenomenon of charging overload of an automobile battery is prevented, and the functions of overvoltage overload and real-time power supply monitoring of the device can be realized.
本发明公开了一种具有测压功能的充电枪及充电桩,包括枪体、手持部、启动组件和充电头和小板充电头内设置有的充电电极与充电线电性连接,且充电线的另一端与小板上的输入端子电性连接,小板上设置有输入端共模电感、电量计量芯片、共模电感、第一X电容、电流互感器、继电器、和输出端,小板上设置有电源输出端,本装置通过设置有译码器的存在,可以通过译码器将汽车电池终端的充电反馈信号进行处理,使得充电完成时便可以将信号传递至微型继电器,通过微型继电器的控制断开电路连接,从而防止汽车电池出现充电过载的现象,通过此便可以实现了本装置过压过载和实时监测电源大小的功能。
