I understand the skepticism, unplugged. The range of conditions under which the heater is energized is complicated to observe. If it's really hot, or I select a temperature that the system will never achieve, the heater won't energize. But it's completely repeatable - at warm to somewhat hot...
Our 2013 FFE apparently energizes its range-sapping cabin heater to modulate the A/C cooling whenever the cabin achieves the HVAC system's set target temperature. This imposes the load of both the A/C compressor and the heater on the main high-voltage battery pack.
I've written a long blog post...
I'm curious: What EVSEs are those of you reporting this behavior employing? I'm using an Aerovironment EVSE-RS Plug-in model. I recently contacted Aerovironment, just to see if they were familiar with the symptom. I suspect that it's actually the FFE causing the symptoms. They've corresponded a...

After getting the Focus Electric, I had five frustrating days of not getting a second "confirmation" between the FFE and MFM (after four 24+...
