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...
