The Design and Implementation of CAN Communication Module in the Electric Car DC Energy Meter
In order to meet the needs of communications between charging control DC meters and electric vehicles which is designed for new energy supply and operating model of electric vehicle implemented specifically for the state grid,this paper designs the CAN communication unit of charging control DC meters.The design of the communication module is used for communication with electric vehicles,such as reading and writing data,communication with the upper machine through the USB/CAN converter,and making statistics,analysis and processing of the electric vehicles electricity consumption.The actual test results show that the CAN communication module developed in this paper fully meet the communication requirements of the charging control DC meters.
