Why charger power matters
A higher-power charger can shorten charging time, but the vehicle's onboard charging capability, electrical installation and available supply still limit what you can actually use.
Estimate your EV's charging time, daily electricity demand, monthly charging cost, and whether your current home electrical capacity is likely to handle your charging setup.
Use the prefilled values as a starting point, then adjust them for your situation.
Estimates only. Actual charging time, demand and electrical safety depend on the vehicle, charger, wiring, breaker protection, tariff structure and installation conditions.
Daily energy is estimated from your daily driving distance and EV efficiency. Grid energy is adjusted for charging losses. Charging time is estimated from the energy you need and the selected charger power. The home-load check adds your charger power to other simultaneous household demand and compares the result with your chosen sanctioned load.
A higher-power charger can shorten charging time, but the vehicle's onboard charging capability, electrical installation and available supply still limit what you can actually use.
If your daily energy requirement is modest, a lower-power charger running across a longer charging window may cover daily use without needing the highest-power wallbox.
For installation, cable sizing, protective devices and sanctioned-load changes, always use the vehicle manufacturer's documentation and a qualified electrical professional.
