kW

Estimated household demand while the car is charging.

The maximum power accepted by the onboard charger.

What it calculates and what it does not

  • The estimate adds an indicative 10% allowance for charging losses.
  • Effective power is limited by the vehicle's maximum AC charging rate.
  • It does not calculate prices or confirm that the current installation is suitable.
  • The final solution requires checks on the panel, protection, cable route and applicable rules.

Frequently asked questions about home charging

Does the result tell me which charger to buy?

No. It compares power and charging time using your data. Final compatibility depends on the vehicle, installation, protection and cable route to the parking bay.

Do I need to increase contracted power?

Not necessarily. Dynamic load management can adapt charging to real-time household demand. A technician should check actual data before recommending a change.

Can I use the domestic socket comparison?

The tool shows it as a time reference. It does not confirm that an existing socket, circuit or protection is suitable for continuous charging.

Does the calculator replace an installation survey?

No. It is free initial guidance. The company must check the panel, protection, cable route, available power and any required documentation.
