To infinity and beyond. Charging error to 100%+

[AllenXS]

Last month I had a charger installed at my new home, finally moving from L1 to L2 charging.

L2 is a lot better way to enjoy the car.

Last week I had a charging error show up on the car. Somewhat concerned I unplugged.

later I took the car for a drive and it was showing 100%. I thought that strange as it was set to 90% and with a charge fault thought it would be less.

After a few miles it was still showing 100%. This continued for about 10 miles until it dropped back.

My assumption is the fault allowed it to charge to 103 or so percent which I guess is possible just highly unusual.

Not worried as it hasn’t happened again, just interested in thoughts. Be great before a long trip!

No idea what the charger fault is, but it cannot charge to 103%. The car computes how full the battery is by trying to precisely measure the voltage and a few other things to compute "how full" the battery is. It is an imperfect process, especially as temperatures change - so the result you saw was nothing more than the fact that the amount of electrical potential in the battery cannot be perfectly measured.

Your assumption is incorrect. Regen plus warmer Temps keep it at 100% for a while, sometimes.

Would you consider 23 degrees (f) warmer temps?

Usually as soon as I drive off the car will drop a% point so it was unusual. Don’t think my regen is that good.

Maybe you broke physics? Have you tried anything else yet? Perpetual motion? Faster-than-light travel?

Faster than light - only in my Mach-e

Faster-than-light travel?

Well, his real name is Zefram Cochrane, so …
