You are focusing on the wrong metric. How much does the percent state of charge increase over the 8 hours of charging?
For a 120V supply, the stock EVSE should pull about 12A, so the charging rate is nominally 1.4 kW, but with losses more like 1.3 kW. If the charging rate averages 1.3 kW over 8 hours, that should add about 10 kWh of energy to the battery pack. So, you should see the SOC jump by at least 50% after an overnight charge.
Do you know how to switch the dashboard view to display State of Charge (SOC)? If not, watch this video:https://www.youtube.com/watch?v=5zxLxPdAJhg
