Ford has possibly solved the poor cold weather HV battery problems found in the FEH. The FFH HV battery takes its ventilation from the cabin where the driver can control heat and cooling. Cold weather is not something I have a problem with here in South Florida but a majority of FEH/MMH folks have complained about EV problems during the winter. After all, what good is a 47mph EV speed that can't be used much during the winter. I love my strong 40mph EV speed in my '09 FEH, but 47mph would be much better.

Now that we have the SGII Xgauge we can monitor the temperature of the HV battery. With control of cabin heating, we can control HV battery temperature much better. Even a portable duct system could be rigged up to be used for heat or cold air to the battery vent directly. We'll have to wait to see what adjustments if any will be needed in the FFH, but Ford has made some great improvements.

That will certainly be an improvement in the cold weather, although I only keep my interior heated with body heat and gloves right now ;) The kids would like it if I needed to turn the heat on for the HV Battery, so this is definitely a smart innovation. It would have been really nice if they had figured out how to vent the heat from the engine directly to the HV battery though, so that less heat would be lost between the front blowers and the pack in the rear.

I wasn't aware that we could monitor the HV Battery temp with the XGauge. I'll have to look it up and start tracking and analyzing it.

Having the aggressive EV cut off at 47mph would definitely help too. I have grown very weary of the double tap to go EV in the winter when the LGA worked so much better in the summer. Well, I'm glad Ford is listening and getting better!

I just hope there are enough of these around for me to take a test drive!
