We use the term Wallbox to refer to the fixed point of recharging electric vehicles. Wallbox refers to the physical system that provides electrical power to the vehicle plugged in by a cable. This device, powered by alternating current, either in single or three phase mode, brings together several components that make the whole system an integral recharge system.
What fundamental characteristics must the Wallbox have?
Although there are different models of fixed charging points for electric vehicles, we can pick up the fundamental functions of the Wallboxes to protect the electrical system to which the car is connected and protect the batteries.
- Wallboxes are used to protect against electric shock and avoid voltage peaks during the charging process to harmonize the power of the current. In this way, the Wallboxes protect the batteries of electric cars.
- The Wallbox can be used to know at all times the electricity consumption, measure the energy consumed. This function is very useful because its use avoids surprises in the payment of electricity and even resolves conflicts in the case of being installed in a community car park.
- Wallboxes can be used to program recharging processes for electric vehicles when taxes are cheaper.
Where are the wallboxs installed?
The wall-box or “fixed point of recharge” is installed, as its name suggests, on the wall of the garage where the relevant electrical installation is to be made. This device receives the energy of the installation of the house or the garage.
What types of connectors use the wall-box?
These fixed recharging points (as they are also commonly referred to) are ready to manage electrical power using various types of connectors. It is important to remember that not all electric vehicles carry the same connection to the network. We can find ourselves from a schuko connection (connection with normal house plug), to specific connections of concrete models like the Sae J1772, Mennekes. These connectors give us the opportunity to connect our vehicle to the network.
Here are some examples of electric vehicles and their particular network connections:
– Nissan Leaf with Sae J1772 load connectors.
– Renault Fluence with connector Sae J1772.
– RenaulKangoo with IEC 62196 connector.
– Renault Twizy with schuko connector.
– Peugeot Ion with connector Sae J1772.
– Volkswagen Golf with Mennekes connector.
– Renault Zoe with Mennekes connector.
– Chevrolet Volt with connector Sae J1772.
