Enter the energy density of discharge and the energy density of charge into the Calculator. The calculator will evaluate the Battery Efficiency.

## Battery Efficiency Formula

BE = EDD / EDC * 100

Variables:

- BE is the Battery Efficiency (%)
- EDD is the energy density of discharge
- EDC is the energy density of charge

To calculate Battery Efficiency, divide the energy density of discharge by the energy density of charge, then multiply by 100.

## How to Calculate Battery Efficiency?

The following steps outline how to calculate the Battery Efficiency.

- First, determine the energy density of discharge.
- Next, determine the energy density of charge.
- Next, gather the formula from above = BE = EDD / EDC * 100.
- Finally, calculate the Battery Efficiency.
- 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.

energy density of discharge = 40

energy density of charge = 50
