Electric Vehicle Charging Controller (EVCC) is a vehicle gauge level electronic control product independently developed by Neusoft Reach, which is mainly used for the charging communication conversion of national standard electric vehicles. After application, the national standard charging system can be directly converted to the European standard/American standard/Japanese standard communication standard. The product adopts platform-based hardware design, in line with the European and American joint charging system of the car / pile-communication terminal, so that the national standard GB/T27930 protocol standard to conform to ISO15118(TLS, PnC, AC), DIN70121, SAEJ1772 protocol standards, directly convert CAN communication into PLC communication, Thus, new energy charging products such as national standard electric vehicles/charging piles/battery power supplies can be quickly introduced to the international market only by simple matching installation, and have been mass-produced in many mainstream models of car companies.
