dlb92 Posted August 10, 2013 at 03:27 PM Report Share Posted August 10, 2013 at 03:27 PM So I set up a go time for 12PM and I went in my garage and at 11:27AM the AC was running. It is plugged into a 120V outlet. I'm assuming it is running the AC for a lot longer and on low because of the 120V power supply so that it does not wear the battery down? Can anyone confirm this?

dlb92 Posted August 17, 2013 at 12:23 AM Author Report Share Posted August 17, 2013 at 12:23 AM (edited) Just got my Clippercreek L2 charger installed $510 + $100 = $610. Car charged up in just under 2 hours. The main battery was depleted and the hybrid reserve was over half way depleted. Can we request that Ford use a calendar for the GO times instead of only 1 week? Edit: For those that missed my answer to the original question--I plugged in a kil-a-watt measuring device and found the A/C turns on 1 hour before departure time on a 120V outlet and runs at 1.33Kwh to slowly cool down the cabin rather than using the car's battery. Edit2: The battery on myfordmobile shows full but evidently it is still slowly charging/topping off the battery.

larryh Posted August 17, 2013 at 12:43 AM Report Share Posted August 17, 2013 at 12:43 AM (edited) I thought for cabin conditioning, the car turns on climate control 15 minutes before the GO time. 1.3 kW is the maximum power the car can draw using the 120 V charger. 1 hour of running AC at 1.3 kW is excessive. It does not require that much energy to cool down the car. I would not expect it to take an hour. It is probably not using that much power the entire time. You should check the amount of energy on the meter at the time conditioning starts and when you unplug the car.

dlb92 Posted August 17, 2013 at 01:08 AM Author Report Share Posted August 17, 2013 at 01:08 AM (edited) What you probably didn't know is that its about 110 degrees F in my garage here and I set it for 65F so yes it turns on and runs at 1.33kwh for about 45 minutes. I measured it the whole time and it was constant. I'm pretty sure it only turns on 15 minutes before GO time if you have a L2 charger.

larryh Posted August 17, 2013 at 01:39 AM Report Share Posted August 17, 2013 at 01:39 AM In order for GO times to work, the car must wake up temporarily to determine what to do. Your result would imply that the car wakes about one hour prior to the GO time to figure out when it needs to start the AC to precondition the car. If it doesn't need to start the AC at the moment, I would expect it to go back to sleep and and wake up again at a later time. If at this later time, it determines it needs to start the AC, it will do so. Otherwise, it would go to sleep again and wake up at a still later time prior to the GO time and check again, and so on.

dlb92 Posted August 17, 2013 at 02:13 AM Author Report Share Posted August 17, 2013 at 02:13 AM (edited) I will find out tomorrow morning when I go to work and let you know since the L2 charger is hooked up. I don't have a meter installed on it so I won't be able to say for sure it is using 3.3kw to power the AC--maybe I can check the display when I get in the car. But I will definitely see when it turns on--hopefully it will only be 15 minutes now. Edited August 17, 2013 at 02:13 AM by dlb92 Quote Link to comment Share on other sites More sharing options...
larryh Posted August 17, 2013 at 07:28 PM Report Share Posted August 17, 2013 at 07:28 PM (edited) I just tried setting a GO time with the 120 Volt charger. The AC turned on 15 minutes before the GO time. The Kill A Watt meter initially showed 10 watts of power. After about 3 minutes, it increased to 1.3 kW. At the GO time the AC shut off and the charger continued to draw 1.3 kW of power until the HVB was fully recharged. I would guess that the heater and AC get their power directly from the HVB. After preconditioning has drawn down the HVB charge a little, the car then begins to charge the HVB. The energy from the charger does not appear to go directly to the heater or the AC. That might explain why the car never draws more than 3.3 kW from a 240 Volt charger for preconditioning no matter how much power the charger supports. The power from the charger is only used to charge the HVB and not to directly power the heater or AC.

dlb92 Posted August 18, 2013 at 05:11 PM Author Report Share Posted August 18, 2013 at 05:11 PM Well it must be really hot in my garage--I set a go time for 1:40 and I went out at 12:59 and my AC was running full blast on a L2 charger.

dlb92 Posted August 19, 2013 at 02:09 AM Author Report Share Posted August 19, 2013 at 02:09 AM So maybe if others are having the same problem I am--if you are leaving at 12PM set the go time for 12:30PM and then the AC will only run for 15 minutes from 11:45 to 12PM.
