The invention provides charging equipment of an electric vehicle and a control method of the charging equipment. The charging equipment comprises a charging pile shell, an electric energy two-way transmission device and a control device, a direct-current bus capacitor of the electric energy two-way transmission device is connected between a PWM voltage source converter of a two-level topological structure and an isolated-type two-way full-bridge DC / DC converter, decoupling and cascading of a first-order power circuit and a second-order power circuit are achieved, and the existence of the direct-current bus capacitor makes the first-order power circuit and the second-order power circuit can work independently respectively; through the PWM converter of the two-level topological structure, electric energy two-way transmission between an alternating-current power grid and a direct-current bus is achieved; through the isolated-type two-way full-bridge DC / DC converter, electric energy two-way transmission between a direct-current bus and a battery pack of the electric vehicle is achieved, and further two-way flow of the energy between the electric vehicle and a power grid is achieved.
Description
technical field [0001] The present invention relates to the field of electric vehicles, more specifically, to a charging device for electric vehicles and a control method thereof. Background technique [0002] With the regulation of national policies and rising oil prices, new energy vehicles have developed rapidly, especially electric vehicles, and major automobile companies have achieved certain research and development results and products. As a representative of new energy vehicles, electric vehicles have the advantages of economy, energy saving, and environmental protection. [0003] At present, the charging equipment for electric vehicles consists of a PWM voltage source rectifier and an isolated DC / DC converter to form a charging main circuit to realize the charging function for electric vehicles. However, the existing electric vehicle charging equipment cannot realize the flow of electric energy from the electric vehicle to the grid, that is, the two-way flow of ele...
