Level 1&2 Electric Vehicle Service Equipment Reference Design


Design files


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.

  • 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

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
