A little confused about these kW numbers, please help clarify for me.

I've seen 2 numbers associated with the Bolt.
11 kW, and 55 kW

I saw a public charging station outside of a Denny's restaurant, stopped by to look at the spec. It read "50 kW". This station only charges $0.50 per hour to charge.

So if I hook up my future Bolt EUV to it, will I get 11 kW/hour delivered to the battery, or will I get 50 kW/hour? I know there are losses due to battery SOC and other factors, so the numbers I posted are ideal/theoretical. Let's assume there's no loss to make it easier to understand.

Thanks!

The "new" 2022 - 2023 Bolts have a Level 2 charger capable of 11 kW, and a DCFC (DC Fast Charge) capability of 55 kW. The one at the Denny's you mention would be DCFC.

How much will get into your battery will vary. Level 2 will almost always put in the maximum kW the station is capable of. DCFC varies depending on the cars current battery temperature, SOC (state of charge), etc.
