My Lightning sat on the dealer’s lot for 4 weeks before I could pick it up. It only lost about 2%. That’s consistent with the article.

^ nice! Our 2013 Tesla Model S routinely uses 3 kWh DAILY in phantom drain, but then again, I have all the connectivity features enabled, so the car can never fully shut down as we routinely use the app to control the charging, air conditioning/preconditioning in the car.

Just got Lightning recently. I took it to our cabin in north with no charging. It sat for 3 days and went from 62% to 59%. This would be almost as much as our 2014 model S. I wonder if there is a setting I’ve missed to reduce drain or is this normal in cooler temp.

I'd say ops normal. The Tesla's vampire drain is minimal when you turn off sentry mode. If it was cooler it likely impacted it, but I'm still happy overall.

Did you check to see how much of that was in the first night when the battery cooled down?

 

[coghlin]

Yes it was spread out evenly.

My truck sat for 4 weeks before I could pick it up this summer. It lost 2% over 4 weeks, with 0% in the first week.

 

[coghlin]

I’m thinking it must be because it’s just above the freezing mark and the battery management is more active. It also could be that I have something set wrong. I will be trying it again this weekend.

 

[coghlin]

Discovered what I was doing wrong. The truck must be locked to stop battery drain. Sat for 4 days and had almost no battery drain.

Will be taking my Lariat ER to the airport this month (New England) and we will be gone 5 days. Any estimates on how much my SOC will decrease? I was thinking that I get to the airport with 90%. Thoughts?

 

[Kawartha Lightning]

My ER definitely loses charge every night if I don’t leave it plugged in (leaving it plugged in, only for BMS, not charging at all, it consumes 5-15 kWh —again adding zero charge. Seems like a lot)

We’re going away in January for seven days and need to leave a car at the airport. It won’t be the lightning. A week in subzero temps, no confidence there’d even be enough SOC to limp to a charger

it consumes 5-15 kWh again adding zero charge

That's 4%-11.5% of total ER battery capacity per night, exponentially more than I have ever observed.

 

[Kawartha Lightning]

Example (no charge added, but I did have scheduled pre-conditioning before I went to work and started the truck so that would use some juice] there’s another thread, where two dudes have identical draw/usage with no charge being added, just BMS and preconditioning to go to work the next day. Granted, I am in Canada where it’s colder but it’s not that cold here yet compared where we will get in January.

this is weird...I am also in Canada, specifically out in the prairies...I don't experience this kind of loss with my truck, usually charge once a week to 75% if I am not driving out to the cottage.

it would take me a whole week to lose that kind of kwh you are losing daily...

SR XLT here...

That's not what I would consider vampire drain.

I drive back and forth to work about 40km round trip per day (25 miles) and try to use HVAC lightly. It’s sucking back quite a bit leaving it plugged in overnight and preconditioning etc ( just over 400kWh in November). The Lightning is a little cheaper to operate than my 10 year old BMW inline 6 twin turbo (which is a lot more fun to drive and I don’t have to worry about heat, range etc - or leaning on the pedal when I want too). The Beamer might cost $15 per month more in gas (vs electricity) to go the same distances. Its close. In the warmer weather, the Lightning would pull ahead, but I am down at least 30% on range already and it’s not that cold here yet. Maybe I wouldn’t be drawing so much if I didn’t leave it plugged in overnight (and only charged it when needed without keeping it plugged in and preconditioning before my morning drive ) but that’s what everyone’s recommending

1-3%.

25 miles x 25 week days in November 2022 divided by 1.7 mi/kWh consumption = 368 kWh
Or, 15 kWh per work day round trip 25 days = 375 kWh
