ELECTRIC VEHICLE CHARGING BALANCE CONTROL METHOD AND SYSTEM

WIPO Patent Application WO/2023/098262

A1

An electric vehicle charging balance control method. The method comprises: step S10, acquiring the current time, and executing step S20 when an optimization time point is reached; step S20, collecting data of each charging pile in an area, and when a new vehicle is connected to or disconnected from a charging pile or when the charging power of the charging pile changes, executing step S30 to step S50; step S30, resetting the power supply pre-distribution power of each phase of a power grid in the area; step S40, sorting charging powers Pj of all the charging piles in the area in a descending order of absolute values from largest to smallest; and step S50, starting from the charging pile having the maximum charging power, traversing all the charging piles, and switching a charging pile to a corresponding phase of the power grid according to the positive/negative state of the charging power Pj. Further disclosed is an electric vehicle charging balance control system. By means of the method, a charging phase of each charging pile can be dynamically controlled in real time, such that a power grid load of an area where the charging piles are located is balanced, and the method is simple and can be easily used.
