home EV charging energy, monthly cost, charger power and overnight-time calculators

Model home EV charging from your own tariff

Estimate home charging energy, monthly electricity cost and idealized charging time without assuming one vehicle.

Tools

Calculate monthly energy from sessions and kWh per session.

Apply an electricity price to charging energy.

Estimate time from energy and average charger power.

Compare charge time with an available overnight window.

Home-charging cost depends on the marginal electricity price you model.

Real charging can be limited by the car, installation or state of charge.

Grid energy can exceed energy stored in the battery.

Available overnight time is often more important than peak power.
