EVCC 2.4 Quick-Start Guide
The Electric Vehicle Charger Controller (EVCC) integrates charger CANBUS control, J1772 Level 2
charging, and BMS head end functions. Charge parameters are configured, saved in nonvolatile memory, and
used when charging to control a CAN enabled charger. The EVCC connects to analog "cell loop" Battery
Management Systems (BMSs) as well as CAN enabled BMSs.

The EVCC is configured using a simple serial interface. This interface is used for configuration and
debugging, but is not required for normal operation. Diagnostic commands are supported to verify proper
wiring, to trace CANBUS messages, and to retrieve charging history.
The EVCC supports the SAE J1772 standard. J1772 defines the physical connector and protocols used
between the charging station (known as the "Electric Vehicle Service Equipment"), and the Electric Vehicle.
The J1772 Proximity signal is used to determine if the charger plug is present. The J1772 Pilot signal is used
to start and stop charging (by enabling and disabling the contactor in the EVSE). The J1772 Pilot duty cycle
