TIDA-00637
Level 1&2 Electric Vehicle Service Equipment Reference Design
TIDA-00637
Overview
This verified reference design provides the foundation you need to implement a J1772-compliant Level 1 and 2 electric vehicle service equipment. It showcases safe failure modes using our peripheral drivers along with integrated fault checking. It has a configurable power delivery control and implements self-metering to ensure maximum power delivery to the electric vehicle (EV). It also includes a highly accurate energy meter for $/kWhr-based billing models.
Features
- Full implementation of J1772-compliant service equipment
- High current relay drivers for support of high current contactors
- Standardized pilot wire signaling protocol
- Integrated utility meter-grade energy measurement
- GFCI fault detection and protection
- Option for communication daughter card add-in
