Choosing an EV charger for home: a practical guide to safe and efficient charging

An EV charger for home can make everyday use of an electric car or plug-in hybrid easier. However, choosing one is not simply a matter of selecting the highest number of kilowatts. A charger needs to suit your consumer unit, car, charging location and driving habits.

Many buyers run into the same pitfalls:

  • A 22 kW EV charger sounds appealing, but your car may only be able to accept 11 kW or less.
  • A charging station is marketed as “smart”, while only a basic timer function is available.
  • A long cable is convenient, but a heavy 3-phase EV charger also requires a suitable connection and installation.
  • An IP rating is mentioned without explaining whether that protection applies during use or only when stored.

Use the checks below to compare an electric car charger based on practical features rather than marketing claims.

Three technical points to check first

1. Charging power and number of phases

Charging power determines how quickly your car can charge at home, but the lowest limit is what matters: the charger, the electrical installation or the car’s onboard charger.

  • A 3.5 kW portable EV charger connected to a Schuko socket is suitable for slow charging, for example overnight.
  • A 7 kW charging station generally uses a single phase and requires a suitable circuit and cabling.
  • An 11 kW EV charger usually works with three phases and requires a suitable 3-phase connection.
  • A 22 kW EV charger can only be used to its full capacity if both the car and the consumer unit support it.

So first check the maximum AC charging capacity of your Tesla, Volkswagen, BMW, Hyundai, Kia or other Type 2 vehicle. A plug-in hybrid charger with 3.7 kW may already be sufficient in many situations, as a plug-in hybrid’s battery is smaller.

2. Connection, cable and installation

A Type 2 charging cable compliant with IEC 62196-2 is the standard connection for European electric cars and many plug-in hybrids. Check that the cable really has a Type 2 plug on the vehicle side and that its length suits your driveway or garage.

Also consider the following:

  • 5 metres is often practical for a fixed parking space.
  • 7 to 10 metres provides more freedom of movement, but is heavier and more difficult to store.
  • A mobile charger with a CEE plug is not the same as a wallbox for electric cars that is permanently connected to the installation.
  • A Schuko charger uses a domestic socket. If it is to be used for extended periods, have the circuit, plug and cabling checked.

For a fixed home charging point, the installation should be assessed by a qualified installer. Consider the available grid capacity, residual-current protection, cable cross-section and circuit layout. A product with a high charging rating does not automatically make an unsuitable consumer unit suitable.

3. Adjustable charging current and smart features

A charger with an adjustable charging current can be useful when you do not always want to charge at maximum power. Some models offer settings such as 8A, 10A, 13A, 16A, 20A, 25A and 32A. This allows you to match the charging power to the connection or time of use.

An EV charger with an app may offer functions such as:

  • starting or stopping charging;
  • setting a charging schedule;
  • adjusting the charging current or power;
  • viewing charging data;
  • receiving a notification when the session is complete.

However, check which app is used, whether Wi-Fi is required and whether the charger can also be operated without the app. With a model featuring dynamic load balancing, you should also check whether the required meter or installation components are included.

Recommendations for different situations

How this product avoids the pitfall

The charger explicitly states 11 kW, 16A and three phases. This makes the required connection clearer than with products that only claim a general charging speed.

Key benefit & advantages

5-metre cable, Wi-Fi and Bluetooth control, charging schedule, LCD screen and adjustable current from 8A to 16A according to the product description.

Installation and everyday use

Position a home charging point so that the cable does not cross a walkway or pull on the plug when taut. For outdoor use, the charging unit’s protection rating and the connector’s seal are important. The IP65 or IP66 rating quoted for some models describes protection against dust and water under certain conditions; always follow the instructions for actual use.

Also consider the total charging costs. The car’s energy consumption does not change solely because of the charging power. However, you may benefit from a lower electricity tariff when you set a charging schedule, if your energy supplier offers different rates. An app function is useful here, but is not essential for every user.

Frequently asked questions about home EV chargers

Do I need a 3-phase connection for a home EV charger?

Not always. A 3-phase connection is required to use an 11 kW or 22 kW EV charger to its full capacity. For a 3.5 kW mobile charger or a 7 kW charging station, a single-phase connection may be sufficient. Have your consumer unit checked before ordering.

How long does a home charger last?

Its lifespan depends on how often it is used, how it is installed, moisture, temperature and how the cable is handled. Check the plug and cable regularly for cracks, discolouration, loose contacts or damage. Do not use a damaged charger and follow the manufacturer’s maintenance instructions.

Is a mobile EV charger cheaper to run than a wallbox?

The electricity consumption per kilowatt-hour charged is not automatically lower because of the type of charger. The main differences are the purchase price, installation and charging power. A mobile charger can be convenient without permanent installation, while a wallbox often provides a fixed parking solution and additional features such as charging schedules or load balancing.
