As a long-time Tesla owner vampire drain has always been a concern. In the early days we would lose 7-10 miles a night in range from drain on the battery due to the BMS thermal management. Obviously, with a Tesla there's a great deal more going on with many systems requiring battery power to keep the car connected and available. Tesla has their act together now and I can leave my car for three or four days and maybe lose a couple of miles of range at the most.
It's been exactly one week since I took my Juiced CCX for a ride. Due to travel to the East Coast as well as lousy rainy weather it's been sitting in our garage for a week. In Southern California our garage gets down to around 50F at night and probably 70F in the day.
I noted my battery voltage on my last ride: 49.9V and thought it would be interesting to power on the bike 7 days later and see if there was any vampire drain.
I turned on the battery and controller and the voltage shows as an even 50.0V. So no battery drain whatsoever for the bike to sit unused for a week. Makes me wonder how long I could leave it before seeing some degradation. Obviously if I left it for 6 months there'd be something - but I'll never have an opportunity to test it out.
This might be expected by most of you but to me this was an unexpected surprise.
