This seems untrue?
Do we suffer from this? Do we have the sleep mode that they turned off?
Kohler Controller said:Tony, do you know if the battery thermal system is engaged when Pre-climate control is activated?
TonyWilliams said:We don't have significant vampire loads, however the flip side to that is that we don't have active battery temperature control.
If you're in a hot area and you want to keep your battery pack cool, you will need to either be actively charging or have the car left in READY mode. Yes, you can leave your key fob in the car and lock the doors with the mechanical key that is in the fob.
Leaving the car in READY will have a significant vampire load. Charging at 120 volts will draw a huge portion of that energy to battery temperature control (when the battery is hot or cold), again a huge vampire load.
There is no free lunch.
TonyWilliams said:Yes, the battery gets 0.5kWh of "pre-conditioning".

How did you figure that one out? ...

This is from a recent article on the topic: "According to Tesla, there is no thermal management of the Model S battery when the car is turned off..."

The greencarreports.com article states that the parasitic vampire drain in Teslas is due to keeping electronics powered up. Hmmm.
If true, then the RAV4 and Tesla are more similar than we thought: active thermal battery management only when the cars are on.
My Model S has active thermal battery management while it is OFF. However, the current SW release allows owner to program it to put the Model S in "sleep mode". In sleep mode, there is no thermal battery management.TonyWilliams said:tgreene said:Yes, Tesla has active thermal battery control, but it appears that is not the cause of the "vampire" drain.

Interesting. The Roadster was/is definitely "active" all the time, up to "bricking" the battery pack.

You've got some great connections... Too bad Toyota isn't trying to make a real go at an ev. You could provide some great feedback to them.
Instead they seem to be have made a minimal effort and they slipped you a lemon to boot!
