Description

This verified TI Design provides the foundation that you need to implement a J1772 compliant Level 1 & 2 electric vehicle service equipment. It showcases safe failure modes using TI’s 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 a 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
