The invention discloses a charging gun with charging control and metering functions and belongs to the technical field of charging pile metering. With the charging gun adopted, when an electric vehicle is charged by existing direct-current charging, the distance between a meter and a charging gun head is too long, and as a result, the consumption of metered electric energy is large, and a final electric energy metering result is influenced. According to the charging gun of the invention, an electric energy metering device calculates an electric energy signal passing through a cable, and outputs the calculated electric energy signal to a man-machine interaction unit and a controller through a communication circuit; the man-machine interaction unit is fixedly embedded in a shell of a charging gun body,displays the received electric energy signal and provides a port for a user to set an electric energy charging electric quantity value, and sends an electric energy charging electric quantity value setting signal to the controller; and the controller controls a switch and the control circuit of the switch to be switched off or switched on according to the received electric energy charging electric quantity value setting signal and the electric energy signal outputted by the charging gun. The charging gun of the invention belongs to the technical field of the charging of electric vehicles.
一种具有充电控制及计量功能的充电枪,属于充电桩计量技术领域,本发明解决了现有直流充电给电动汽车充电时,计量表计与充电枪头之间的距离过长,造成计量的电能消耗量大,影响最终的电能计量结果的问题。本发明电能计量装置计算经过线缆的电能信号,并将计算获得的的电能信号通过通信电路输出至人机交互单元和控制器;人机交互单元嵌固在充电枪本体的壳体上,对接收的电能信号进行显示,并为使用人员提供设置电能充电电量值的端口,将电能充电电量值设置信号输出至控制器,控制器根据接收的电能充电电量值设置信号和电能计量装置实时计算的经过充电枪输出的电能信号,控制开关及其控制电路的断开或闭合。本发明适用于电动汽车充电技术领域。
