Overview

The TIDC-EVSE-Wi-Fi® verified reference design details how to implement J1772-compliant level 1 and level 2 electric vehicle service equipment (EVSE) with added Wi-Fi functionality. The CC3100 network processor enables highly-embedded devices like the EVSE to easily connect to an existing wireless network or directly to a device. By integrating this functionality in an EVSE, the design is capable of remote-power monitoring and control of the charging state of the connected electric vehicle.

Features
  • Implementation of J1772-compliant service equipment
  • Wi-Fi support for remote monitoring and control of EVSE
  • High-current relay drivers for support of high-current contractors
  • Standardized pilot-wire signaling protocol
  • Integrated utility meter-grade energy measurement
