Electric vehicle alternating-current charging pile

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of chargers, in particular to an electric vehicle AC charging pile, which is suitable for charging lead-acid or colloidal battery packs of electric vehicles, tour buses and hybrid vehicles. Background technique [0002] At present, domestic electric vehicles have just emerged, and the charging and battery life of electric vehicles is almost always charged at home or at work with a unique socket. Once the vehicle runs out of power during operation, it will fall into a situation where there is nowhere to charge. Even if there is a socket nearby, because the electric vehicle charging current is very large, the existing socket cannot meet the needs of electric vehicle charging. Contents of the invention [0003] In order to solve the shortcomings of the prior art, the present invention provides an AC charging pile for electric vehicles, which can satisfy electric vehicles in public places by swiping cards to p...
