Charging management system and method for charger of electric vehicle

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.
