METHOD & BOUNDARIES
What the estimate means.
This is a transparent planning model. It separates driving energy from charging losses, then tests whether the connected window and infrastructure can restore the target SOC.
Distance to discharge
Planning km/kWh = (certified range ÷ battery kWh) × range factorCertified cycles are labelled and not treated as guaranteed real-world range.
Battery to wall
Wall kWh = battery discharge ÷ charge efficiencyLosses are explicit. A 90% efficiency means the meter supplies more energy than reaches the battery.
Schedule to cost
Interval cost = charging kWh × applicable retail ratePower is clipped by the EV, charger count, charger rating, site limit and departure deadline.
Planning limitations
No battery degradation curve, temperature model, auxiliary/preconditioning load, demand charge, tax, solar generation, export credit, DC taper curve or network charge is modelled. Confirm vehicle specifications, tariff rules and electrical capacity before making an investment decision.
