For you math geniuses out there: If gas weighs 6 pounds per gallon, how much does a [View all]

KW weigh in my electric car? I'm afraid I'm overloading my EV with the stuff in the trunk so I figure I'd reduce the KW of charge to carry more.

One nice thing about an EV - my dealer gives free oil changes for the life of the vehicle.

Every time my vehicle runs low on fuel, I go to a charging station. Since everyone is adding a 3% fee for charging, does anyone know a cashing station I could use instead? Is that what an ATM machine is for? Where do they hide the cable to connect to my car?

Even years back, people complained that gas stations overcharge for gasoline because the gas in the hose goes back into the tank even if it has already passed the meter. Is that the same with EVs? Is there any way to get those extra amps still in the line to continue to flow into my car?

You do realize this is the humor forum, don't you? The WEIGHT of a KW or a KWH vs the WEIGHT of gasoline? Wonder Why Friday #6

Most batteries nowadays are sealed systems. Change in weight should be undetectable. eppur_se_muova Friday #5
