Is this an attempt to weigh electrons ?

Charging does not add electrons, it increases voltage (aka 'electric pressure.') It is an increase in potential energy.

Since I was weighing the just car,

How much does an unjust Leaf weigh?

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Charging does not add electrons, it increases voltage (aka 'electric pressure.') It is an increase in potential energy.
e=mc^2

So

m= e/c^2

Add energy, the mass goes up.

Do check my math, I might have gotten it wrong.

Most everything around here is wet during the rainy season. And the rainy season is long.

You are right. I presume it means that the voltage increase implies an internal change in inertia.

My EV is almost always wet, thanks to all the rain we usually get.

Then why do you think the car's so overweight? U.S. truck weight scales are limited to no more than a 40 lb error @ 10 tons to be in tolerance, so that doesn't explain an almost 5.4% overweight. 1-2% variation I could understand, but over 5%?

It’s probably due to all that extra emissions equipment they need in CA. :)

April Leaf sales under 1k. What’s happening? Other choices stealing the leaf thunder? Supply constrained?
