Abstract

The invention discloses a power divider applied to a double-gun direct-current charging pile. The power divider is applied to the technical field of charging, and is used for solving the technical problem of resource waste of an existing double-gun direct-current charging pile. The power divider applied to the double-gun direct-current charging pile comprises a charging module, a positive bus, a negative bus, a charging controller, a positive high-voltage direct-current contactor and a negative high-voltage direct-current contactor which are arranged in the charging pile, wherein the positivehigh-voltage direct-current contactor is arranged on the positive bus; the negative high-voltage direct-current contactor is arranged on the negative bus; the positive high-voltage direct-current contactor is respectively connected with a positive electrode of the charging module and an output end of the positive bus; the output end of the positive bus forms a positive input end of an external first charging gun and a positive input end of an external second charging gun respectively; the negative high-voltage direct-current contactor is connected with a negative electrode of the charging module and an output end of the negative bus respectively; and the charging controller is connected with the positive high-voltage direct-current contactor and the negative high-voltage direct-current contactor.

Description

technical field [0001] The present application relates to the technical field of charging, in particular to a power divider applied to a dual-charger DC charging pile. Background technique [0002] At present, the traditional one-piece power splitter used in the dual-gun DC charging pile on the market, the power output of the two guns is either evenly distributed, that is, each outputs half of the power, or one gun outputs full power and the other gun does not output. Power, that is, each gun only has two gears of half power and full power output. In this case, when the vehicle BMS (Battery Management System, battery management system) has a large demand, such as 80KW, the charging pile output The power can only output 60KW or 120KW. When the charging pile outputs 60KW, the charging power is insufficient and it takes a long time to fully charge. When the charging pile outputs 120KW, in order to match the needs of the vehicle BMS battery management system, the power output ca...
