EV home charging current vs overnight energy recovery chart

Compare lower-current and higher-current home EV charging energy-recovery bands before using the charging-time calculator.

Chart boundary

Does not calculate charging time, guarantee vehicle range, approve EVSE current, account for all vehicle efficiency, or replace the EV charging-time calculator.

Overnight energy recovery bands

The curve compares 8, 10, and 12 hour energy windows before losses, then hands exact range and battery inputs to the calculator.

12 A at 120 Vabout 12-17 kWh over 8-12 h

Slow recovery; practical for modest daily driving.

16 A at 240 Vabout 31-46 kWh over 8-12 h

Lower-current Level 2 with useful overnight energy.

32 A at 240 Vabout 61-92 kWh over 8-12 h

Common Level 2 planning band before charger losses.

48 A at 240 Vabout 92-138 kWh over 8-12 h

High home current with more service-capacity pressure.

Decision reference

Show approximate kWh recovered over fixed overnight windows before users enter exact battery, charger, efficiency, and distance values.
