Multi-power module address acquisition and uniform state control method based on address state table

Abstract

The invention discloses multi-power modules address acquiring and a homogeneous state controlling method based on an address state table. Physical addresses of sub-power modules are acquired by a system, a start control is conducted on all the sub-power modules correspondingly according to the physical addresses of the sub-power modules, a feedback output voltage is sampled to determine the corresponding relation between all the sub-power modules and primary electrical circuits, and meanwhile the sub-power module corresponding to a charging gun is determined, wherein the sub-power module is defined as a default attribution module. The state and the number of times of using of all sub-power modules are acquired by the system dynamically, and dynamic allocation is conducted on sub-power modules by the system through the number of times of using of the sub-power modules, the states of all the sub-power modules and the total demand quantity of modules required by the charging gun. According to the multi-power modules address acquiring and the homogeneous state controlling method based on the address state table, the problem of the dependency relationship of the multiple sub-power modules with the primary electrical circuits is solved, and the workload of the maintenance and use operation of a direct current charging pile is reduced.

Description

technical field [0001] The invention relates to the field of power supply technology, in particular to a multi-power supply module address acquisition and uniform state control method based on an address state table. Background technique [0002] In the past 10 years, with the development of the new energy industry, battery materials and charging technology have been continuously optimized and improved. Correspondingly, the demand for higher charging rates of fast charging piles has also been continuously increased. [0003] At present, domestic DC charging piles basically use a combination of multiple low-power power supply modules to achieve large power output. The greater the total power of the charging pile, the more low-power power supply modules are used. In the current design of DC charging piles, the address setting of each low-power power supply module is closely related to the primary electrical circuit, so the workload for address assignment of these low-power pow...
