SAE J1772:2010 Compatible Active Vehicle Side Control Board Module

This little module AVC1 came together a few years ago.  It improves the J1772 pilot communications and power control.

It is intended for conversion vehicles to improve the safety and compatibility with public J1772 charging stations.

Units like our adapters take advantage of the differing pin lengths to insure ground mates first and breaks last.  The pin lengths also insure the power pins are mated before the pilot and the pilot  ends before the power pins separate.

This module monitors the latch switch in the J1772 system and removes the pilot signal when your thumb is on the connector latch further insuring power is off long before the connector separates.

The J1772 connectors are not designed to ever mate or separate with power on.

There are 8 connections and the module is powered by the vehicles 12 volt system, current draw is always under 20ma.

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

The SPDT relay has a set of contacts for your use.

Soft start or stop of charging or inhibiting motion would be typical uses

The new version is AVC2.

It is the same unit packaged in a box with mounting ears and better terminal marking.

There are 2 types of AVC2 modules

The
AVC2 is for vehicle inlets that have a 2.74K resistor between ground and the PROX pin, like the ITT units.


The
AVC2.r is for vehicle inlets that do not have the 2.74 K resistor between ground and the PROX pin.  The resistor is built into the module and this would be used with our aluminum connectors.

The boards are tested and ready to go.   The AVC2 r AVC2.r price is $39.99, shipping is included for the USA.  We have a package with a vehicle inlet available.

These photos show the resistor.  It is a 2.74K ohm 1% 1/2 watt flameproof type.  Any 2.7 K (2,700 ohm) 5% or 10% resistor will due.  The resistor is needed for reliable operation of the AVC2 modules and part of the J1772 specification.

The AVC2 is for vehicle inlets that have the 2.74 K resistor between ground and the PROX pin.

The
AVC2.r is for vehicle inlets that do not have the 2.74 K resistor between ground and the PROX pin.

The Blue wire is the PROX (proximity) wire.
