Estimate ideal recharge time between two states of charge.
Use the energy capacity specified for the battery.
State of charge when charging begins.
Must be greater than the starting state.
Use sustained battery-side charging power if known.
Assumed fraction of charger energy stored in the battery.
Energy added to battery
10.50kWh
Ideal recharge time
3.80h
Constant charger power and a single efficiency factor. Real systems may taper near full charge and may limit power because of temperature, generator capacity, battery controls or concurrent loads.
