Rapid Battery Drain From 100%

[atunker]

I’ve had my Lightning Pro for a couple months now and have been loving it. It did stop working the very first day of ownership due to a faulty charge plate which was resolved by the dealership which I’ll have to share on another thread. I’ve been away the last several weeks and left the truck with my wife. To save on expensive west coast gas, she took to the Lightning to Vegas from California and has been driving it these last two weeks there. Before I left town I set the target charge level to 100% to maximize her mileage as this is her first experience with an electric vehicle, and she was going to be using it away from home. When she uses the vehicle, it shows charge complete to 100% both in the Ford app and in the vehicle. But every time she backs down the driveway, it consistently drains instantly to 94-96% after backing up only 20 feet. I haven’t experienced this personally as when I’m home, I keep the target charge level set to 90%. Has anyone else experienced this with their Lightning? I’m wondering if there is an issue with the battery/charging system or potentially related to the original charge plate issue.

She also get‘s horrible efficiency (less than 1.8 mi/kWh) but she has been driving mostly on the highway and is a speed demon.

Northern or Southern CA? It could be the cold if it is Northern CA...

Are you charging on 120 or 240? How long after reaching 100% is she driving?

She’s been in Vegas with the lows being in the 60s so I wouldn’t think it’s that.

110V charging, usually driving a few hours after charge has finished.

less than 1.8 on the highway going ~75 is pretty normal.

IMHO, set it at Ford-recommended 90% or 95%, if you must. Don't worry about the dark science behind what the battery is doing to protect itself.
