Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Purchased energy = battery energy/(efficiency/100). Cost = purchased energy × price.
Using battery energy to add = 40 kWh, electricity price = 0.25 money/kWh, charging efficiency = 90 %, the result is 11.1111111 currency. Change these example inputs to match your task; use the method above to check each step.
What to keep in mind
