I was able to wire the charging “AC on” relay to the controller’s KSI relay.  The relay is setup so that the battery voltage is on when the AC is off (not plugged in).  This means that the controller won’t go until the car is unplugged as a safety interlock.

When the AC is plugged in, the power goes to the battery vent fans via another relay.  That relay is on when the pack is charging, but off during the maintenance (”trickle”) phase.

We took a little shopping trip south to Sunset Valley today.  The trip included about 9 miles of highway driving at 60 MPH!  Very fun.  The RAVolt did fine: it takes a constant drain of juice to maintain 60 MPH and climbing hills pulls down the pack pretty hard.  Overall, it was a great trip.
