Lou Valencia Posted January 17, 2015 at 01:07 AM Report Share Posted January 17, 2015 at 01:07 AM When my car is plugged in and fully charged, if I remote start to warm it up, it's using power from the battery vs. wall power. When I get in, about 10% of the battery is drained. Can I get it to use power from the plug for this? Quote Link to comment Share on other sites More sharing options...
larryh Posted January 17, 2015 at 01:21 AM Report Share Posted January 17, 2015 at 01:21 AM You have to use My Ford Mobile to precondition the car. Create a GO time and set the desired temperature. The car will then use electricity from the wall outlet to warm up the car. You need a 240 V charger for this to work well. It will begin preconditioning the car up to an hour before the scheduled GO time if it is really cold. If it is not that cold, preconditioning starts about 15 minutes before the GO time.

jdbob Posted January 17, 2015 at 07:42 PM Report Share Posted January 17, 2015 at 07:42 PM I have a C-Max rather than a Fusion but when I have my car plugged in and use the remote start (using the key fob) it does start drawing power from the EVSE to supplement the battery. At max power the climate system will draw about 5kW. If you have a 240V EVSE about 3.3kW will come from the wall instead of the battery, for a 120V EVSE only about 1.4kW will come from the wall. In either case the battery will be drained some but more for 120V. Hybridbear 1 Quote Link to comment Share on other sites More sharing options...
shaggy314 Posted January 25, 2015 at 10:17 PM Report Share Posted January 25, 2015 at 10:17 PM I've notice when sitting in a car charging I couldn't get the heater (or seat heaters) to come on when I hit the on button unless I unplug, defeating the purpose. I had been hoping to sit in the car with the seat heaters on while the car charges. Quote Link to comment Share on other sites More sharing options...

Allow the seat to dry thoroughly.• Operate the heated seats unless the engine is running. Doing so can cause the battery to lose charge.

shaggy314 Posted February 19, 2015 at 05:03 AM Report Share Posted February 19, 2015 at 05:03 AM Well there you go... I wouldn't have thought the seat heaters would drain the battery on an L2 charger, but ok. Thanks for finding that for me. -james Hi shaggy314, I did some digging, and found the following in your Owner's Guide: Do not do the following:• Place heavy objects on the seat.• Operate the seat heater if water or any other liquid is spilled on the seat.

When the car is charging via the EVSE the DCDC converter is engaged. Quote Link to comment Share on other sites More sharing options...

When the car is charging via the EVSE the DCDC converter is engaged. Just a minor point. The normal DCDC converter isn't running when charging. The charger in the car produces both high voltage for the traction battery and low voltage for the 12V battery. No idea why they did it that way.
