The invention discloses an
electric vehicle alternating-current charging
pile which relates to the technical field of chargers. The charging
pile is provided with a
control circuit, and the
control circuit is provided with a controller, a charging module, a display, a
relay and a power metering module, wherein the charging module is connected with the controller and used for computing the
electricity consumption quantity; the display is connected with the controller and used for displaying information such as charging
voltage,
electricity consumption power and the like; the
relay is connected with the controller and used as a protection switch; the power metering module is connected with the controller and used for detecting the magnitudes of the
voltage and the current input to a power supply; and the input end of the power metering module is connected with an external 220V alternating-current power supply, the output end is connected with the
relay, and 220V
voltage is output from the relay to charge a storage battery. The invention has the advantages that the
electric vehicle alternating-current charging
pile has small volume, convenient use and simple maintenance, 220V and 16A
alternating current can be output, the charging requirement of an
electric vehicle is satisfied, the commercialized charging of the electric vehicle at public places is realized, and a condition is provided for the generalization of the electric vehicle, so that new-energy vehicles are popularized.
