How long will my EV battery last?

Calculate battery runtime based on power requirements.

You can work out how long an EV battery will last using the following:

  • Appliance Power (kW) (show typical values for reference)
  • EV battery capacity (kWh)
  • Starting battery level (%)
  • Minimum/final battery level (%)

Time (hours) = (starting battery level - final battery level) * EV battery capacity / appliance power


We are working on a calculator to automatically work out how long your battery will last - check back here again soon!

Can I power my whole house or office?
