Prime Loses Charge Sitting Unplugged

1 watt-hour per hour = 1 watt. Typically watt is used as the unit, not watt-hour per hour. Example - 40 watt light bulb, not 40 watt-hours per hour bulb.

 

Put another way, watt-hours per hour is (watts * hours)/hours, which is just watts, with the hours cancelling out. "*" means "multiply", for those not familiar with this kind of notation.

 

Ok, I'm fairly sure I saw my battery capacity decline yesterday. At 9am I ran a short errand and got home with about 98 or 99% remaining indicated on the display. Around 7pm I got in and the battery was at 92%, and just leaving my street it dropped to 87%. My street is probably 1/10 of a mile and I drive around 10-15mph, so it usually uses no measurable amount of charge. I did have the AC going, but it should use around 1% or less during the he time it takes to drive down my street.

It's possible that I sat on my key and held the remote AC button sometime during the day, but I think that's extremely unlikely.

The battery temperature was probably cool in the morning, and it was around 92F by the time I left.

I'll have to see if this is repeatable.

 

I would recommend on a few of your tests that you re-set Trip A mileage to zero & then drive it under normal conditions till you fully kill the battery. This way you'll have another data point as to whether or not you get your roughly ~25 miles of battery range when done.

I made it something like 27 miles (mostly highway) on the remaining 92%, so the range seems fine. What am I looking for specifically?

 

That's it, I just figured another data point would be useful.

~27 miles of mostly higher speed highway driving sounds very good, you're certainly not really regenerating at 60 or 70 mph like you would be in the city. So ~27 miles is pretty good...

I got to work with 51% battery, and it was the same when I left. Most of the time it doesn't lose charge. That's around 30 miles round-trip with the AC on, and I had about 5% remaining when I got home. Around 5 miles of that was drafting behind a truck because I can't quite make the round trip without charging at work if I don't.
