Abstract

The invention provides an intelligent power distribution system and method for a dual-gun direct-current charging pile of an electric bus. The intelligent power distribution system comprises an alternate-current contactor, a charging controller, a fixed charging module, a distributable charging module, a direct-current contactor module, a motion control module, a switching quantity collection module, a power distribution module, a first gun, a second gun and a bus charging demand collection module used for collecting the charging demand and the preferential charging sequence of buses corresponding to the first gun and the second gun from a battery management system of the buses. According to the intelligent power distribution system and method for the dual-gun direct-current charging pileof the electric bus, each charging unit can be intelligently distributed, and the utilization rate of the modules is increased; and meanwhile, the charging units are grouped for free switching according to the demands of the first gun and the second gun, and in this way, the number of the contactors needed for power distribution is greatly decreased.

Description

technical field

[0001] The invention relates to the technical field of charging piles, in particular to a system and method for intelligent power distribution of double-gun DC charging piles for electric buses. Background technique

[0002] At present, the DC charging piles with dual guns for electric buses with power distribution function on the market can only achieve equal distribution of power when both guns have charging needs, so that the charging modules cannot be used effectively. Taking the dual-gun DC pile with 16 modules (each module 15kW) as an example, according to the charging requirements of the first gun and the second gun, 12 modules can actually meet the needs of the first gun, and 4 modules can meet the charging requirements of the second gun. Demand, according to the current average power distribution plan, the first shot and the second shot are allocated 8 modules, so that it is equivalent to the second shot having 4 modules in an idle state, while the f...
