Abstract

The invention provides an electric automobile AC-DC charging system and an electric automobile AC-DC charging method to solve the technical problems in the prior art that different charging ways cause waste of public resources and the cost of a product is increased. The system comprises a charging unit and a power receiving unit. A charging interface of the charging unit is connected to a charging gun. The charging gun is inserted into a power receiving socket of the power receiving unit to enable the charging unit to charge the power receiving unit. The charging unit includes an AC-DC switching charging device the output end of which is connected to the charging interface, and also a charging management module that is connected to the AC-DC switching charging device. The power receiving unit includes an AC-DC power receiving switching loop the output end of which is connected to the power receiving socket, and also an automobile power receiving management module that is connected to the AC-DC power receiving switching loop. According to the system, a charging mode and a power receiving mode can be switched simultaneously, and a DC fast charging scheme and an AC slow charging scheme can be flexibly applied.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to an electric vehicle AC-DC charging system, and an electric vehicle AC-DC charging method based on the electric vehicle AC-DC charging system. Background technique [0002] Electric vehicles are a new type of green and environment-friendly means of transport, which are gradually being accepted by people for their advantages of energy saving and emission reduction. Its rapid development has led to the popularization and application of its supporting charging facilities. [0003] At present, electric vehicle battery charging generally uses charging piles as the charging interface, and provides AC power or DC power of different voltage levels for electric vehicles for different models. Existing charging piles are mainly divided into AC charging piles and DC charging piles. The AC charging pile provides 220V AC power for the on-board charger of the electric vehicle, and the on...
