How does home EV charging work?

A dedicated home chargepoint supplies electricity safely to a compatible vehicle, usually through a Type 2 connection on modern UK and European cars. The vehicle’s onboard charging equipment determines how much AC power it can accept, while the chargepoint and the electrical supply impose their own limits. The actual charging rate is the lowest applicable limit, not simply the number printed on the charger.

Actual AC charging power is constrained by the lowest applicable supply, chargepoint and vehicle limit.

Vehicle acceptance, the chargepoint setting and the assessed electrical supply can each limit the charging rate. Protection, earthing and connection arrangements require project-specific assessment.

7.4 kW versus 22 kW charging

7.4 kW versus 22 kW charging

Approximately 7.4 kWUp to 22 kW
230 V single-phase, often up to 32 AThree-phase supply, often up to 32 A per phase
Subject to property load capacity and vehicle acceptanceRequires suitable three-phase supply and vehicle capability

Most ordinary UK homes have single-phase supplies, so a 22 kW AC charger cannot simply be added to achieve 22 kW without the necessary supply and vehicle compatibility. Some vehicles accept less than the maximum AC chargepoint rating. The installation survey assesses what can be safely delivered.

Illustrative charging calculation

28 kWh ÷ 7 kW ≈ 4 hours

28 kWh ÷ 7 kW ≈ 4 hours

Illustrative charging calculation: adding 28 kWh of energy at an average 7 kW would take roughly four hours before allowing for charging losses and tapering or vehicle limits. This is arithmetic, not a guaranteed charge time for a particular car.

Smart charging and off-peak electricity

Smart charging and off-peak electricity

Smart charging allows compatible chargepoints to schedule energy delivery, including during lower-cost periods under suitable electricity tariffs. The savings depend on actual prices, charging needs, vehicle settings and the chargepoint’s features. A connected charger must also be configured for reliable operation with an appropriate network connection and supported app.

UK rules apply to many privately sold smart chargepoints; compliance of the specific selected unit must be verified. See GOV.UK smart chargepoint guidance.

Scheduled off-peak charging

Arrange charging within suitable tariff windows, allowing for the energy your vehicle needs.

Smart charger controls

Use the selected charger’s supported app, connection and operating settings.

Tariff and vehicle compatibility

Check supplier terms, vehicle settings and the specified chargepoint’s supported features.

Charging convenience

Build a practical routine around parking, daily mileage and available charging time.

Can solar panels charge your electric vehicle?

Can solar panels charge your electric vehicle?

Yes, subject to equipment and controls. Some smart chargers can respond to surplus solar generation so more of the car’s charging energy comes from your roof. However, vehicle charging has minimum current requirements, household loads fluctuate and solar production changes with weather. A charger may pause, import some energy or follow a scheduled strategy depending on its operating modes. Compatibility with the PV inverter, metering arrangement and energy-management system must be checked.

If you’re planning both technologies, we can consider the EV charger alongside your Solar Panels and Solar + Battery design. It is often more useful to plan the electrical distribution and cable routes together than to treat each addition independently.

Optional example only. Surplus charging requires a chargepoint, PV/metering arrangement and controls with demonstrated compatibility. Minimum charging current, variable household demand and changing sunlight may lead to pauses or grid import. A standard charger does not automatically provide solar-surplus control. The diagram does not show every protection device.

Dynamic load management and electrical capacity

Dynamic load management and electrical capacity

Dynamic load management and electrical capacity

Adding a charger increases demand on the property’s electrical supply. Dynamic load management can measure overall site consumption and adjust the charger’s output to help avoid exceeding a configured supply limit. It is not a substitute for a proper electrical assessment, correct protection, suitable earthing arrangements or distributor requirements. Existing consumer units, mains equipment, supply capacity and cable routes all need consideration.

Site metering observes the combined electrical demand against the assessed and configured supply limit.

Adjust EV charging power

Compatible controls may reduce or pause charging as other loads rise, then increase it when capacity becomes available.

Dashed green lines show control information. The available supply is shared by household loads and the vehicle. Dynamic control supplements correct electrical design; it does not replace protection, earthing, supply assessment or distributor requirements.

Good positioning takes account of the vehicle’s parking orientation, cable reach, accessibility, mounting surface, weather exposure, trip hazards and the route back to the electrical supply. Cable runs or groundworks can be significant cost factors, especially where the charger is not close to the consumer unit. The proposed installation should be agreed before work starts.

Parking and charger position

Consider parking orientation, cable reach, accessibility, mounting surface and exposure.

Cable route and access

Agree the cable route, access and any necessary groundworks before installation.

Electrical supply assessment

Review supply capacity, mains equipment, consumer unit, protection and earthing.

Additional works and quotation

Identify alterations, load controls and civil works within the written installation scope.

What affects installation price?

The chargepoint model and features, length and type of cable run, consumer-unit alterations, earthing and protection, load-management equipment, civil works and the adequacy of the existing supply can all affect the quote. A low advertised ‘standard installation’ price is only comparable when the inclusions are clear.
