The EVSE tells the car what it can supply, the car decides what to pull (in terms of amps). *If* you set the EVSE to (say) 24 amps, then it will tell the car it can supply 24 amps, and (I would expect that) the car will pull a MAX of 24 amps (24A x 220V = 5.28 kW ; 32A x 220 = 7.04). Not all of that energy goes into the battery - there is some current loss.

All that is completely understood. I know the car will pull

**max** 24 amps in that situation. That is the whole point of the L2 protocol. But I am interested to find out how much it will actually pull.

Not all of that energy goes into the battery - there is some current loss.

For sure. It gets worse, I guess: if the car itself pulls the full 24 amps on a 24 amps setting, even more amps will go over the line, as there are losses upstream also (although I am not sure it is really

*current* that gets lost, as current should be the same all over the line up to the OBC).

In terms of circuit breakers and safety, the guideline in the U.S. has been for a very long time that a continuous pull on an electrical line should not go past 80% of the max rating. So on a line with a MAX rating (i.e., a circuit breaker) of 30A, I myself personally would not plug anything that draws over 24A for an extended period (more than 10 mins).

Fortunately, I am not in the U.S. (yes, that was a joke

).

Lastly, I can't tell you what *your* EVSE and car combo do when you set the EVSE to (say) 30A. Are you setting the EVSE's max draw to 30A (and the car will be pulling a continuous 30A)? The only way to know is to try it. My car when turned on (Chevy Spark EV) will show how much energy is being 'regenerated' (pushed back into battery). So if I am at a DCFC and turn on the car, I see the kW being pushed in. You might be able to do the same on the Bolt. Or maybe there are other ways to see exactly how much energy is being taken in on the Bolt.

I hope this helps.

Neither me, nor EldRick does have a Bolt (or Ampera e) yet to try with. Nor do I have the proper EVSE (don't know about EldRick). That is the whole point of asking this question here. But it is not about

*my* EVSE, IMHO. It is about how a Bolt behave when

*any* EVSE is set to 20, 24, 30 ... amps. As the protocol is the same for all EVSEs. So, I was hoping somebody else would be willing to try it. Or already knows ...

The reason for wanting to know upfront is that I would like to know whether I will be able to charge with 20 amps or only 16 amps with my current setup, as 20 amps allow me to add 25% more kms or miles per night. Currently my house is connected to the grid with 3 x 25 amps. Upgrading my connection to 3 x 35 amps will cost me about 1000 USD

*yearly*, so I am a bit reluctant to do so ....
