Description

Technical Field

[0001] The utility model relates to a charging device, in particular to a combined charging device for supercharging and fast charging. Background Art

[0002] With the increase of environmental protection efforts, the expansion of third-party travel business and the improvement of people's acceptance of electric vehicles, the production and sales of electric vehicles in China have increased significantly. With the popularization of electric vehicles, new requirements have been put forward for the layout and construction of charging equipment. Charging equipment includes charging piles and chargers composed of battery stacks and front-end machines. Charging piles include controllers, relays, AC / DC modules and charging guns. The charging piles convert the AC power of the power grid into DC power and then charge the electric car through the charging gun; the charger includes a battery stack and multiple front-end machines. The battery stack is equipped with a controller, relays, AC / DC modules and DC bus. The front-end machine is equipped with a controller, relays and charging guns. The AC power of the power grid is converted into DC power and then connected to the DC bus; multiple front-end machines are connected to the DC bus. The front-end machines include super-charging front-end machines for charging electric trucks or vans, and fast-charging front-end machines for charging electric cars. The front-end machine takes power from the DC bus according to charging needs and charges the electric car and electric truck or van through the charging gun. In some application scenarios, since the production and operating costs of the battery stack are higher than those of the charging pile, and the efficiency of using the supercharging pre-end machine and the fast-charging pre-end machine at the same time is not high, the supercharging pre-end machine or the fast-charging pre-end machine is prone to idleness, and the corresponding parking lots will also be idle, increasing operating costs.
