Map the working day.
Collect daily distance, payload, parking location, return times and the hardest seasonal route. Start with vehicles whose work is predictable and whose charging location is controlled.
FLEET TRANSITION
Build around
operational readiness.
Replace headline range with a practical view of routes, energy and vehicle availability.
Establish the energy envelope.
Use measured consumption where possible. Add operational reserve and assess exceptional days separately. The planner supplies a transparent first calculation from your assumptions.
Test site and vehicle fit.
Confirm import capacity, charger compatibility, parking access and the departure schedule. Average power is a lower-bound energy balance, not an installation specification.
Pilot, measure, then expand.
Compare planned and actual grid energy, availability, cost and missed departures. Refine charging schedules and service arrangements before committing the entire fleet.
Cost scope
The calculator estimates electricity and fuel expenditure. A full total cost of ownership case must also include vehicle purchase or lease, finance, residual value, maintenance, insurance, charger works, demand charges and taxes.
Commercial development concept
A future owner could build a permission-based fleet assessment service around these tools, adding route data, qualified partners and installation support. These services are proposed and are not currently offered here.
