Required charging energy calculator

Charging energy exceeds delivered energy when a storage cycle has losses.

Ein=Eout×100RTEE_{\text{in}} = \frac{E_{\text{out}} \times 100}{\mathrm{RTE}}

Worked example

Given

  • EoutE_{\text{out}} = 420 kWh
  • RTE\mathrm{RTE} = 84 %
Ein=420×10084=500E_{\text{in}} = \frac{420 \times 100}{84} = 500
