Abstract

The invention provides a charging system and method for a charger of an electric car. The charging system comprises a DC module and a charger management system (CMS), wherein the charger management system (CMS) comprises a charger battery management system (CBMS) and a charger charging management system (CCMS); the charger battery management system (CBMS) is connected with the charger charging management system (CCMS) and the DC module through a CAN bus 1; the charger battery management system (CBMS) is connected with battery management systems (BMS) of the car through CAN buses 2; according to collected data like the charging voltage and current of the battery management systems (BMS) of the car and the charger, the charger is converted into an active charging mode from a passive charging mode, logic computation is carried out according to a certain strategy, more reasonable charging voltage and charging current are output within the demand range of the battery management systems (BMS), and unsafe hidden dangers of the conventional charger due to the passive charging mode are eliminated.

Description

【Technical field】 [0001] The invention belongs to the technical field of electric vehicle charging, and relates to a charging system and method for an electric vehicle charger. 【Background technique】 [0002] With the progress of society and the enhancement of environmental protection awareness, electric vehicles are gradually favored because they are powered by vehicle-mounted power supplies and can solve the problems of exhaust emissions from fuel vehicles, pollution of the environment, and high energy consumption. And the charging problem of electric vehicle is the problem that people pay close attention to very much, and it is related to popularization and promotion of electric vehicle. [0003] In the actual use process, the control module of the charger needs to establish a physical connection with the vehicle to be charged, and then communicate through the data communication line, judge whether to perform charging operation according to the communication information w...
