The mileage being displayed is only a guess (we call it GOM or guess-o-meter). The number depends on various things. State of charge of the battery, temperature, past driving, among others.I don't recall seeing another thread on Power Management, so I thought I'd start one. I have a specific issue, but perhaps we could pin this one and share both problems and successes with improving EV performance.
Here's my post:
My ID.4 is now a couple of weeks old, and I've charged it a few times. I have it set to stop charging at 80%, and each charge has brought the mileage to ~250 miles. However, this latest charge brought it to 232 miles; this seems a significant gap to 250, but maybe it's within some margin of error 🤷♂️
But here's where I'm really befuddled: the next day, I got in the car and it registered 220 (it lost 12 overnight?) and drove literally 1 mile. During that short drive, he estimated mileage remaining had further dropped to 200. While I understand the miles remaining are just an estimate, it seems I lost 20% of my 250 target in less than 24 hours after a charge, and after driving just one mile.
