Enter the battery capacity (kW-h) and the charging power (kW) into the Calculator. The calculator will evaluate the EV Charge Time. 

EV Charge Time Formula

EVCT = BC / CP

Variables:

  • EVCT is the EV Charge Time (hours)
  • BC is the battery capacity (kW-h)
  • CP is the charging power (kW)

To calculate EV Charge Time, divide battery capacity by the charging power.

How to Calculate EV Charge Time?

The following steps outline how to calculate the EV Charge Time.


  1. First, determine the battery capacity (kW-h). 
  2. Next, determine the charging power (kW). 
  3. Next, gather the formula from above = EVCT = BC / CP.
  4. Finally, calculate the EV Charge Time.
  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 capacity (kW-h) = 50

charging power (kW) = 100
