Battery nameplate capacity calculator

Capacity must cover delivered energy after the allowed discharge depth and one-way conversion loss.

E_{\text{nom}} = \frac{E_{\text{req}} \times 100 \times 100}{\mathrm{DoD} \times \eta}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

E_{\text{nom}} = \frac{360 \times 100 \times 100}{80 \times 90} = 500

Symbol	Meaning	Unit
$E_{\text{nom}}$	nameplate DC energy	kWh
$E_{\text{req}}$	required AC energy delivered	kWh
$\mathrm{DoD}$	permitted depth of discharge	%
$\eta$	DC-to-AC discharge efficiency	%

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
