Why you should install a wall charger at home

Having your own wall charger at home makes charging faster, safer and more reliable. This is what you need to know.

Electric vehicles usually come with a Mode2 charging cable included. Mode2 cables have a type2 plug that fits the inlet in your car in one end, and a regular plug designed for ordinary wall sockets in the other. Contrary to what some new owners of electric vehicles believe, this cable is only intended emergency use, when no other charging options are available.

Everyday use of the Mode2 cable and a regular wall socket for charging is not recommended for several reasons, amongst them are;

  • Regular sockets are not designed to withstand high throughputs over long periods of time. Charging through a wall socket should never exceed 10A.
  • Regular sockets are usually not connected to dedicated circuits. With other devices using from the available power, charging becomes unreliable.
  • Regular sockets don’t have adequate earth fault monitoring and protection.
  • For the reasons listed above, Mode2 cables are limited to 10A / 2,3 kWh, much less than the charging capacity of most cars.
  • Daily connection and disconnection of the plug rapidly causes wear.

Benefits of installing a wall charger at home.

Charge Faster. Because a wall charger allows you to make use of the full charging capacity of your vehicle. While charging through a Mode2 cable and regular socket is limited to 10A and 2,3 kWh, a wall charger is installed with a dedicated 16A circuit or higher. Wall chargers also come either with a mounted Mode3 cable, or with an outlet for a separate Mode3 cable. Mode3 cables come in several dimensions, all with greater capacity than a Mode2 cable. With a 16A circuit you can choose a Mode3 cable giving you a charging effect up to 11 kWh. Since wall chargers are installed with a dedicated circuit, charging times become reliable and predictable.

Charge Safer. Because a wallcharger is designed for charging of electric vehicles and fulfills all  relevant safety regulations*. A wall charger is connected to a dedicated circuit with a larger load capacity and appropriate fuse, and it has earth fault protection type B and DC protection.
The wall charger also warns you of any errors, and stops the power supply when the vehicle is fully charged.

Having a wall charger installed may also increase the value of your home, making it an even better investment for the future.
