How much does electricity weight? Like if you charge your EV, does it weigh more than when the batteries are on “empty”?

Does “electricty” or whatever it’s called that goes into your electric vehicle battery, have mass or weigh anything? My car has a 100KW battery. Is the weight substantially different when it has 0 charge versus when it is fully charged? It seems like a lot of energy goes into the battery, it must add to the net mass of the vehicle?

The battery in the electric car doesn’t store electricity. It uses electricity to drive a chemical reaction in a battery. That chemical reaction is reversed to power the car.

There are not weight changes you could measure on a scale that is capable of weighing something as heavy as a car. There are weight changes, but they are much to small to measure directly.
