Charging of electric commercial vehicles

Vector’s charging controller VC-EVCC-P supports charging via roof-mounted pantographs and via inverted pantographs. The communication with the charging infrastructure is realized via a J1939 connection or by a CAN-to-Wifi gateway.

The VC-EVCC-P (electric vehicle communication controller for pantograph charging) is suited for 24-VDC in-vehicle electrical systems. In addition to the classic roof-mounted pantograph docking to the charging station from the roof, the charger supports inverted pantographs. Here, the pantograph is located at the charging point and from there establishes a wireless connection with the electric vehicle.

The wireless communication (bases on IEEE 802.11a/n) with the charging infrastructure is carried out by a CAN-to-Wifi gateway. Charging communication is enabled in accordance with the Oppcharge version 1.3.0 protocol. In case of the on-roof pantographs, the connection to the vehicle is done via a CAN channel using the J1939 higher-layer protocol. The device supports diagnostic messages based on DM1, DM13, and J1939 network management.

The controller with three CAN interfaces is installed in the vehicle. Additionally, it supports UDS (unified diagnostic services) and power line communication. The operation voltage can range from 10 VDC to 32 VDC. Operation at temperatures from -40 °C to +85 °C is possible. The unit complies with protection classes IP6K6K, IP6K7, and IP6K9K. The CAN-to-Wifi gateway is IP65-protected.
