Abstract

The invention discloses a charging system power distribution method. The method comprises: receiving a power distribution request sent by a charging pile; acquiring state information of each power module in the idle queue; calculating a health value of each power module according to the state information by utilizing a load balancing algorithm; and selecting the optimal power module from the idlequeue according to the health value, and allocating the optimal power module to the operation queue of the charging pile. According to the invention, the optimal power module is selected from the idlequeue according to the health value and is allocated to the operation queue of the charging pile, thereby achieving the purpose of balancing the loss of each power module, effectively reducing the fault rate of the power modules, improving the stability of a charging system, and reducing the probability of huge loss. The invention also provides a charging system power distribution system and device, and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of charging systems, and in particular to a method, system, device and computer-readable storage medium for power distribution of a charging system. Background technique [0002] In recent years, my country's new energy vehicle industry has developed rapidly, but the low mileage of power batteries and long charging time are still important factors restricting the development of new energy vehicles. In order to reduce the charging time, the advantages of high-power fast charging piles will be more prominent. In order to be suitable for new energy vehicles with various power levels, the high-power fast charging piles currently on the market use multiple power modules in parallel to output electric energy. During the charging process, the output power of the modules and the number of modules can be dynamically adjusted to meet the requirements. Charging requirements of new energy vehicles with different power ...
