It does seem really high. Perhaps his Energi was charging the 12V battery during this test. It may also have been running the battery fan. The Energi doesn't have liquid TMS, just a fan. It will run as soon as the car is plugged in if the battery is warm.GladeStorm said:Sounds like the author's battery/battery management system has a problem. The normal vampire draw for the Focus is about 2.5 watts, not 70 watts. If the temperature is too hot or cold the TMS will cycle, but his graph doesn't show cycling; and you wouldn't want to avoid TMS conditioning by leaving it unplugged anyway.
The FFE will also trickle charge the battery when temps are very cold (below freezing).hybridbear said:When the Energi battery is cold the car will trickle charge it as soon as it is plugged in to work on warming up the battery before doing the quick charge during the value charge window.
Yes, but that is a short process. As I've reported on elsewhere, we commonly see the FFE charge immediately during winter upon being plugged in at home for somewhere from 3-15 minutes depending on how cold the battery is. The Energi owner's chart shows a consistent power draw for many hours. This is not at all consistent with the behavior of the FFE when connected to a 240V EVSE.jmueller065 said:The FFE will also trickle charge the battery when temps are very cold (below freezing).hybridbear said:When the Energi battery is cold the car will trickle charge it as soon as it is plugged in to work on warming up the battery before doing the quick charge during the value charge window.
I've seen mine charge for a good hour or more, not just 15 minutes--depending on temperature and if I have it parked outside or not.hybridbear said:Yes, but that is a short process.
