Charging management system and method for charger of electric vehicle
First Claim
1. A charging management system (CMS) for a charger of an electric vehicle, comprising:
- a charger grid micro-dispatching system (CGMS) module, which is responsible for communicating with a power supply grid centralized controller, interpreting received parameter information data according to a certain strategy, outputting an interpretation result, and sending said interpretation result to a charger charging management system (CCMS) module;
a charger battery management system (CBMS) module, which is responsible for communicating with a battery management system (BMS) of the electric vehicle, receiving various communication and charging parameters sent by the BMS, interpreting the various communication and charging parameters according to a certain strategy, outputting charging requirement parameters and sending said charging requirement parameters to said CCMS module;
a charger vehicle-dispatching management system (CVMS) module, which is responsible for communicating with said CCMS module and collecting multiple built-in parameters of the charger, and meanwhile responsible for communicating with a user vehicle dispatching center and sending the multiple built-in parameters of the charger to the user vehicle dispatching center;
a charger network management system (CNMS) module, which is responsible for communicating with an intelligent network cloud platform, receiving and sending multiple parameter information, and meanwhile indirectly communicating with a user terminal device through the cloud platform; and
said CCMS module, which is a core of the CMS, responsible for communicating with said CGMS module, said CBMS module, said CVMS module, and said CNMS module, and meanwhile responsible for a control of a direct current (DC) module, a control of a vehicle power distribution unit (PDU), battery diagnosis and protection, charger self-diagnosis and self-protection, BMS diagnosis and protection, vehicle diagnosis and protection, and fault recording.

Abstract
A charging management system (CMS) and a charging management method for a charger of an electric vehicle are provided. The CMS includes a charger grid micro-dispatching system (CGMS) module, a charger battery management system (CBMS) module, a charger vehicle-dispatching management system (CVMS) module, a charger network management system (CNMS) module, and a charger charging management system (CCMS) module. An intelligent safety redundant strategy and a fault recording strategy are introduced, and multiple related parameters of a battery management system (BMS) are built in the CBMS module, so as to realize an intelligent active protection during charging the electric vehicle. Meanwhile, through analyzing the BMS and characteristic data of a power battery, cooperating with the CCMS module, adopting a multi-dimension data analyzing and controlling strategy, and outputting an optimized flexible curve current based on battery charging, life time of the battery is lengthened.
