A LITTLE KNOWLEDGE. A BETTER CHOICE.
The best charger is the one that fits your car, your electrical supply and your daily routine.
With AC charging, the car's onboard charger converts the incoming electricity for the battery. DC fast charging uses external conversion and can offer much higher power when the car supports it. A 22 kW AC unit is not the same as a DC fast charger.
kW is the charging power. kWh is energy added to the battery. Adding 30 kWh at a steady 7 kW takes roughly 4.3 hours before charging losses and vehicle limits. This is an illustration, not a promise for a specific car.
Many 7.4 kW AC models use single-phase supply; 22 kW AC models typically require three-phase supply. Your electrician must check available load, earthing, protective devices and the cable route against the exact model's instructions.
Connector compatibility and the vehicle's onboard AC limit must both match. Share the vehicle's make, model, year and charging-port details. Do not assume a charger fits every electric vehicle.
A ROUGH PLANNING TOOL
Energy needed ÷ effective charging power. The result excludes losses, tapering and changing conditions.
Research: US Department of Energy: charging equipment and vehicle limits; Schneider Electric: AC power and phase examples. These explain charging concepts; they do not identify the brand of the products offered here.
