This guide provides general information. Confirm the exact vehicle, charger datasheet, site conditions and current local requirements before purchase or installation.
Estimate the energy that needs to be added
Multiply usable battery capacity by the difference between target and starting state of charge. For example, moving a 50 kWh usable battery from 20% to 80% requires about 30 kWh before charging losses.
Use the lowest power limit
The effective charging rate is limited by the charger, the vehicle and the electrical supply. A 22 kW AC unit cannot force a vehicle's onboard charger to accept 22 kW if the vehicle is rated lower.
Remember the charging curve
Charging is not always constant from empty to full. DC power may reduce as battery state of charge increases or temperature changes. Use a calculator for a planning estimate, not a guaranteed time.
