A charging programme connects vehicles, dwell time, electrical capacity and an operating model. Equipment selection follows those decisions.
Energy and power answer different questions.
Energy, measured in kWh, is the amount a vehicle needs. Power, measured in kW, is the rate of delivery. A 60 kWh requirement at a constant 30 kW battery input takes two hours in an idealised calculation. Real sessions vary with charging curves, temperature and state of charge.
Match the equipment to the stay.
AC charging can suit long workplace or overnight parking; the vehicle’s onboard charger can constrain the rate. DC equipment bypasses that onboard conversion stage, but vehicle acceptance, shared power and the local supply still matter. A higher equipment rating does not guarantee a shorter session.
Define the service before the specification.
Record user groups, access hours, turnover, accessibility, payment approach and escalation arrangements. Fleet depots need departure readiness. Public hubs need successful sessions and understandable pricing. Property sites need fair access and manageable electrical demand.
Ask for evidence you can operate.
Request site drawings, a measured demand assessment, tariff assumptions, product certifications relevant to the location, service coverage, a clear warranty and a tested handover. Have qualified local professionals establish the electrical design and applicable obligations.
