Make charging work around you.

Know the limits of the estimate.

Battery energy added = usable capacity × (target charge − start charge) ÷ 100. Grid energy = battery energy ÷ efficiency. Time = grid energy ÷ minimum(charger output, vehicle limit). Cost = grid energy × tariff.

This is a constant-power planning model. It does not model DC taper, battery temperature, preconditioning, load sharing or queues. Use a realistic average power for fast-charging scenarios; a charger’s peak rating is not the session average. Confirm connector compatibility and manufacturer limits.

Where will you charge?

At home: review parking, tariff and installation with a licensed electrician. At work or a depot: review available power and dwell time. On the road: check the operator’s own availability, connector and tariff information.
