Abstract

The invention relates to a DC charging pile capable of simultaneous output from multiple pistols. The DC charging pile comprises an AC power module, power module groups, contactor groups, a master controller, charging pistols, CAN communication modules and a human-computer interactive module. In the DC charging pile, multiple groups of relatively small power units are arranged in parallel, multiple paths of independent simulation detection channels are designed, and the state detection demand of the pistols is met; multiple paths of DC loops independently output, each loop outputs from a positive end and a negative end of a DC bus through two DC contactors, and a DC high-speed fuse is configured at the lower ends of the DC contactors to isolate an external short-circuit fault of the DC loop; and after the charging pistol is connected with an electromobile, the charging pile charges according to the demands. Through a reasonable circuit design and a control strategy, the division and multi-path output of a power module are achieved, and the simultaneous output from multiple pistols is achieved; and meanwhile, two vehicles and more than two electromobiles are simultaneously charged, and high-power charging is carried out on a vehicle.

Description

technical field [0001] The invention relates to the field of new energy charging, specifically, a DC charging pile capable of outputting multiple guns at the same time. Background technique [0002] At present, DC charging pile equipment mostly adopts the mode of single gun output or double gun output in turn. When charging, only one vehicle can be charged, resulting in too long charging time, affecting the utilization rate of electric vehicles, and greatly reducing the utilization of chargers and electric vehicles. rate, causing unnecessary losses to the entire industry. [0003] In view of the defects in the above-mentioned existing DC charging pile output mode, the inventor actively researches and innovates based on years of rich practical experience and professional knowledge engaged in the design and manufacture of such products, and cooperates with the application of academic theories, in order to create a new type of charging pile. The structure of the DC charging pi...
