Intelligent orderly charging control system and charging control method

Abstract

An intelligent orderly charging control system and a charging control method are provided. The system comprises an embedded controller, a man-machine interface, a power monitoring system, a power electronic device, and a charging unit/charging pile. The embedded controller is connected with the man-machine interface, and is connected with the power monitoring system through an isolation unit. The power monitoring system is connected with the power electronic device and the charging unit/charging pile. The system is designed based on factors including the bearing capability of the battery of a rechargeable vehicle under physical properties of the battery, the output power of a charger, the current capacity of a transmission grid, and the charging demand of users. On the premise of not exceeding the bearing capability of the battery under the physical properties (namely, the damage to the battery is close to zero), a safe and stable charging process can be ensured through cyclic program monitoring and dynamic circuit adjustment based on the load of the charger and the capacity of the transmission grid; and meanwhile, different charging needs of users can be satisfied to be maximum through related optimization control rules and algorithms.

Description

technical field [0001] The invention belongs to the technical field of multi-objective sequential charging control of electric vehicles, and in particular relates to an intelligent sequential charging control system and a charging control method. Background technique [0002] As electric vehicles gradually replace traditional fuel vehicles, the problem of charging electric vehicles is increasingly emerging; especially in the case of a certain transmission capacity of the current power grid, this problem is even more prominent; electric vehicles purchased by users can only be charged at designated charging stations. It is very inconvenient for the battery to replenish energy, and most of the charging adopts a single constant current or constant voltage method, which brings different degrees of damage to the battery. As a result, the user's satisfaction with the charging service process is low, so the above factors seriously restrict popularization of electric vehicles. Cont...
