How to Use the EV Charging Time Calculator
Enter the battery energy you want to add and the charger power to estimate how long charging may take.
Practical Example
Adding 40 kWh with a 7.2 kW charger takes about 5.6 hours in an ideal calculation before allowing for charging losses or power tapering.
Factors That Affect the Result
Charger output, vehicle onboard charger limits, battery state of charge, temperature, charging losses and DC fast-charging taper can all affect real charging time.
Frequently Asked Questions
Why can real charging take longer?
Charging losses and reduced power near a high state of charge can extend the session.
Does a higher-power charger always charge faster?
Only if the vehicle can accept the higher power.
Can I use this for home charging?
Yes. Enter your home charger power and the energy you want to add.
