J1772 Active Vehicle Control Board-AVC2

Have been looking at an ideal solution to connect the charger to Public charging points. Ian Goodman has suggested that EV West in the US have a wee box that essentially does the job that Jim McPherson completed in his youTube video in the last post. There product literature describes the box as a:

Small module to control the Pilot signal in the vehicle and monitor the Proximity Signal from the mating J1772 parts. Contacts are available to inhibit the motor while charging or activate lights around the inlet connector. It is intended for conversion vehicles to improve the safety and compatibility with public J1772 charging stations.

This module monitors the latch switch in the J1772 system and removes the pilot signal when your thumb is in the connector latch further insuring power is off long before the connector separates. There are 8 connections and the module is powered by the vehicles 12 volt system, current draw is always under 20ma. The SPDT relay has a set of contacts for your use. Soft start or stop of charging would be typical uses A led shows when the circuit is latched.

This product is also compatible with the European Mennekes connector and L2 charging stations.’

  • Relay NO – Normally Open
  • Relay C – Common
  • Relay NC – Normally Closed
  • +12 power from the vehicle
  • CH chassis ground (and AC power ground)
  • GND green wire from J1772 Inlet Connector
  • PROX prox wire from J1772 Inlet Connector
  • PILOT pilot wire from J1772 Inlet Connector

      Actually a relief to hear that someone else is having a good experience with it. Do you use the Type-1 J1772 (five pins) in the US?

        5 pin here in the states. It all we have 😦

        Got the 7 pin three phase 32a 7kw stations on the roads and car parks here. Probably never uses so much power because the charger it will use is 20a but i suppose it is nice for the car people.

        It’s really nice for cars. I wish I could pull the full 10kw 40a on my zero :/
