Choosing a home EV charging station: a practical guide to safe, smart charging

A home EV charging station can make everyday use of an electric car easier. Yet many drivers choose a wallbox based only on its maximum kilowatt rating or an attractive app. This can leave you with a charging station that isn’t suitable for your electrical installation, car or available space.

These points will help you compare a home EV charger, a Type 2 charging station or a mobile EV charger.

Common pitfalls when choosing a home charger

1. A higher charging capacity doesn’t automatically mean faster charging

A 22 kW charging station can only actually deliver 22 kW if three conditions are met:

  • Your home has a suitable 400V three-phase connection.
  • The consumer unit and wiring can handle the load.
  • Your car’s inverter or onboard charger supports 22 kW AC charging.

Many electric cars limit their own charging capacity to 7.4 or 11 kW. In that case, a more powerful wallbox won’t charge the car any faster, but it may result in higher installation costs.

2. “Smart charging” doesn’t always mean load balancing

Wi-Fi, Bluetooth and an app-enabled charging station are useful for starting, stopping and scheduling charging. However, this doesn’t automatically mean the station measures your home’s total electricity consumption.

With dynamic load balancing, the charging current is adjusted when, for example, an oven, heat pump or washing machine is drawing a lot of power. So check that this feature is explicitly listed in the product specifications, and whether additional monitoring equipment or installation is required.

3. A Type 2 connection doesn’t tell you everything about the cable supplied

European electric cars often have a Type 2 connection, but a wallbox may come with:

  • a fixed Type 2 charging cable;
  • a Type 2 socket, which means you’ll need to supply your own charging cable;
  • a mobile cable with a CEE or Schuko connection.

So check whether a cable is included, how long it is and whether it’s suitable for the current you need. A 5 or 7-metre cable gives you more flexibility, but also takes up more space.

Important specifications for charging an electric car at home

Charging capacity and number of phases

For many households, an 11 kW charging station is a practical choice. It usually works with a three-phase connection and 16 amps per phase, provided your car supports 11 kW AC charging. A 7.4 kW model works on a single phase and may be suitable for homes without a suitable three-phase connection.

A 22 kW model places greater demands on your electrical installation. According to the product information for various Feyree models, it will usually require a dedicated 32A circuit with three phases. Ask a qualified installer to check in advance that your connection, residual-current protection and cable cross-section are suitable.

Safety features and protection rating

Look for features such as:

  • overcurrent, overvoltage and undervoltage protection;
  • earthing and overheating monitoring;
  • residual-current protection;
  • lightning protection, where specified;
  • an appropriate IP rating for a garage, carport or outdoor use.

An IP65 or IP66 rating describes the enclosure’s level of protection according to the product information. The installation location, wiring and setup still matter. Don’t install a charging station somewhere exposed to direct jets of water or where the ground may become flooded.

App, scheduling and energy use

A smart EV charger with Wi-Fi can let you monitor charging remotely and set a start time. This is useful if you mainly want to charge overnight or during cheaper periods. Whether it will actually save you money depends on your energy supplier, tariff and current rates.

Also check the app’s reliability, the connection types it supports and whether you can set the charging current. A display on the charging unit can be handy if you’d rather not open the app.

Recommended models for different users

Suitable for: Budget-conscious beginners
dé EV Charger with App 3.7kW 10m Single-Phase

dé EV Charger with App 3.7kW 10m Single-Phase

Installation and everyday use

Have a fixed wallbox connected by a qualified installer. A dedicated circuit, correct residual-current protection and suitable cables matter more than the charging capacity printed on the packaging. Don’t use an extension lead or an unsuitable adapter for a fixed charging solution.

After installation, check that:

  • the cable reaches the charging port comfortably;
  • the plug stays clean and dry;
  • the app connects to your home network;
  • the set current doesn’t exceed what the circuit can handle;
  • the charging station is suitable for indoor or outdoor use.

For a plug-in hybrid, 3.7 or 7.4 kW is often enough, as its smaller battery usually can’t make use of the same charging speed as a fully electric car. Whether you drive a Tesla, Volkswagen, BMW, Mercedes-Benz, Audi, Renault, Hyundai, Kia or Volvo, the onboard AC charger in your specific model will determine the charging capacity.

Frequently asked questions about home EV charging stations

How much does it cost to charge an electric car at home?

The cost depends on the number of kilowatt-hours used, your energy tariff and any fixed charges on your contract. An app can schedule charging, but it doesn’t guarantee savings. Check off-peak rates yourself and look at your actual energy use in the app or on your energy meter.

How long does a wallbox last?

Its lifespan depends on how often it’s used, how it’s installed, exposure to moisture, temperature and maintenance. A charging station with a suitable IP rating, sturdy cable and correct installation can be suitable for regular use. Replace a damaged cable or connector straight away, and stop using a faulty charger.

Do I need a separate charging station for every electric car?

Not always. Cars with a Type 2 connection can often charge from the same AC wallbox, but the maximum capacity varies by vehicle. Also check whether the wallbox has a fixed charging cable or requires a separate charging cable for electric cars, which you’ll need to buy yourself.
