The emperor has no clothes
Michael - I regularly get 204 miles on an 80% charge on my P85. Of course, the vampires begin to eat away at that over time.
Every 24 hours I lose 3.5% of my maximum P85 charge. If I keep my P85 at 80% charge (66 kW) I lose 4.5 % everyday. And every day my main battery drops, I lose even a greater percentage. And on the day I have 10 kW in my battery, I lose 33%. And the next day, with 7 kW left, I lose.................. my main battery.
Vampire loss is a big deal. IMO, vampire loss needs to be fixed sooner rather than later. I have the luxury that I can plug my MS in every night in a insulated garage.With winter arriving, vampire loss combined with kW needed to keep that main battery safe and warm makes the long term health of the main battery from losses a looming threat. I will have no choice at what level to charge at 0 degrees in January. The only option will be at 90%. And I will need to preheat the MS cabin before I leave and to keep the main battery warm at 0 degrees ambient temp when I arrive at my outdoor parking spot. At night many users will have to adjust their charging rate (amperage) at night to both heat the main battery while charging and to completely recharge their battery at 0 degrees to coincide with when they leave the house at 6 am on a frigid Wisconsin morning. This is not a user friendly end state.
The above scenario may not be a big deal in Northern California, but it is a big deal in many other parts of the country that get seriously cold in the Winter. TMC needs to get vampire losses fixed now, not in January when owner concerns start surfacing.
NOW is the time for TMC to start fielding the firmware solution, not in 4 months. Testing hibernation/sleep mode now will give them the opportunity of not bricking a main battery.
I can see the MS choosing to program a warning to the owner via the 17 inch center stack that it is 0 degrees outside and the center stack stating in big red letters, "plug in and select hibernation mode". Or automatically select hibernation mode if the end user does not do it just to protect the main battery.
I would rather have my MS take a minute to wake up at 0 degrees than not to wake up at all from a bricked battery.
As I mentioned, I have an insulated and warm garage. My garage never freezes. I am lucky. I can wait. Some users to do not have my setup.
This is the 800-pound elephant in the room.
