| J1772 Active Vehicle Control
Board - AVC2.r View Wiring Diagram AVC2.r Option AVC1 came together a few years ago. It improves the J1772 pilot communications
and power control. It’s 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 A LED shows when the circuit is latched. The new version is AVC2. It’s the same unit packaged in a box with mounting ears and better
terminal marking. 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.
