Question about electricity consumption

[user47592]

I just had a Tesla Wall Connector installed. I have the max output current set at 48 amps. I drive a RWD which charges at max with 32 amps.

If I charged my car for 1 hour. Would the electricity bill be the same if I had the max output current set at 48, 40, or 32?

In your case, yes, since your car wont charge any faster than 32amps.

I didnt understand your question at first, because its fairly obvious that a car charging at 48amps would use more electricity (thus cost more) over a car charging at 32amp, but then I re read it and realized you were saying "because I have a car that has a max charge rate of 32amps, does it matter / does it cost me more if I commission the wall connector for a higher speed?

The answer in your case is "no" like I said, since your car will only charge at 32amps (on a Level 2 wall connector), no matter how fast the wall connector can provide.

Thanks for the prompt replies.

I guess the car is asking for 32 amps and that's what I'm consuming and that's what I get charged for.

Likewise, a hair dryer that plugs into an outlet asks for more electric so it consumes more and be billed more compared to a lighter household appliance.

Thanks again!
