Charing pile power supply control method, storage medium, control device and charging pile

Abstract

The invention discloses a charging pile power supply control method, a storage medium, a control device and a charging pile, and aims to solve the problem of high damage rate due to different chargingpower supplied by a plurality of charging machines in the same charging pile. According to the technical scheme, the charging pile power supply control method comprises the following steps: matchingall charging machines for charging according to the charging machine number, wherein the sum of the charging power supplied by the in-charging charging piles is less than or equal to the required charging power; acquiring average charging power needing to be supplied by each charging machine according to the charging machine number and the required charging power, wherein the average charging power supplied by any one of charging machines is equal. By adopting the charging pile power supply control method, each charging pile keeps the output charging power the same according to the charging pile number in the charging process of the charging piles in order to reduce the damage to a certain charging machine, so that identity is kept as much as possible.

Description

technical field [0001] The invention relates to a charging pile, in particular to a charging pile power supply control method, a storage medium, a control device and a charging pile. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. Generally, new energy vehicles will be equipped with a battery management system to manage the battery. It usually has the function of measuring the battery voltage to prevent or avoid abnormal conditions such as battery over-discharge, over-charge, and over-temperature. [0003] The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall, and installed in publ...

Problems solved by technology

[0004] At the same time, the charging process is controlled by the battery management system. In order to ensure the service life of the battery, during the charging process, the power is inversely proportional to the charging power, that is, the higher the power, the smaller the charging power. It consists of multiple chargers. The existing power distribution method is to cut into the corresponding number of charging piles to match the power. If one charging pile is enough, then cut into one charging pile. If two chargers are needed to meet the needs, then cut into Two chargers; although this method can match the charging process controlled by the battery management system, the frequently used chargers are easily damaged, so there is room for improvement
