Here's a table you can use for home Level 1 (120V) and Level 2 (240V) charging. It covers all common L1/L2 charging scenarios as defined by the J1772 standard. The 8/10/12 hour columns assume a 10% charging loss due to heat and are there to handle the different peak hour exclusions. Also, the Equinox data is based on what I could find and derive from those findings. I put this together before I found out GM is anticipating the ability to charge to 100% with no battery degradation.

The bold row is the standard AC on-board charger acceptance rate for reference. The numbers in (parenthesis) in the 8/10/12 hour columns are range estimates based on the KW number in the cell. Many of these range estimates are longer than the published range estimates, but are included for completeness.

Given that GM has said the Ultium batteries can be charged to 100% with no degradation, can you update the chart, obermd?

For me with my feeble 20A 240V L2 charging setup, and a long range (300 mile battery) Equinox EV, I'd be looking at adding 136 miles over 12 hours of charging. Am I reading that right?

If so, 24 hours (2x136 mies) adds 272 miles. Of course I have not driven my Bolt EV that much in a single day except on a road trip to Iowa, so this is worse case scenario for home charging. It also points up the need to make sure you size your home wiring correctly to support a continuous load over 24 hours. My circuit uses 10AWG which is what feeds the 30A clothes dryer.

I considered updating the final two columns as the 100% charge time would only impact those two columns. The rest of the table is accurate as it doesn't consider "maximum" charge, just how many KWh can be delivered on each circuit size in the time given. Also, for me I wouldn't let my EV get to 10% battery - I'd be plugging in before I reached 25% so the final two columns are still good estimates for 25 to 100%.

Edit: I never let my older ICEVs drop below a quarter tank, why would I allow my EV to drop below a quarter tank?
