Enter the battery energy (kWh) and the efficiency (kWh/mile) into the Calculator. The calculator will evaluate the EV Range. 

EV Range Formula

EVR = BE / E


  • EVR is the EV Range (miles)
  • BE is the battery energy (kWh)
  • E is the efficiency (kWh/mile)

To calculate EV Range, divide the battery energy by the vehicle efficiency.

How to Calculate EV Range?

The following steps outline how to calculate the EV Range.

  1. First, determine the battery energy (kWh). 
  2. Next, determine the efficiency (kWh/mile). 
  3. Next, gather the formula from above = EVR = BE / E.
  4. Finally, calculate the EV Range.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

battery energy (kWh) = 53

efficiency (kWh/mile) = 4
