Formula used
Energy needed = Battery capacity × (Charge to % − Charge from %) ÷ 100
Example: 60 kWh battery, 20% to 80%, $0.15/kWh → 36 kWh needed, cost = $5.40.

FAQ
Frequently asked questions
Why does the calculation only need percent to and from?
It calculates the energy delta actually being added to the battery, not the full capacity.
Does this include charging losses?
No, it assumes 100% charging efficiency — actual costs may be slightly higher due to conversion losses.
What if 'to' is less than 'from'?
Please make sure 'charge to' is greater than 'charge from' for a meaningful result.
Do public fast chargers usually cost more?
Often yes — check the specific rate for the charging network you're using.
