What is a Wallbox?

A wallbox is…

We use the term Wallbox to refer to the fixed charging point for electric vehicles. Wallbox refers to the physical system that provides electrical current to the plugged-in vehicle via a cable. This device, powered by alternating current – whether in single-phase or three-phase mode – encompasses several components that make the whole an integrated charging system.

What fundamental characteristics should Wallboxes have?

Although there are different models of fixed charging points for electric vehicles, we can outline the fundamental functions of Wallboxes to protect the electrical system to which the car is connected and to protect the batteries.

  • Wallboxes serve to protect against electric shocks and prevent voltage spikes during the charging process to harmonize the power of the current. In this way, wallboxes protect the batteries of electric cars.
  • Wallboxes serve to constantly monitor electricity consumption, measuring the energy consumed. This function is very useful as its use prevents surprises in electricity bills and even resolves conflicts in the case of being installed in a communal parking lot.
  • Wallboxes can be used to schedule the charging processes of electric vehicles when rates are cheaper.

Where are wallboxes installed?

The wallbox or “fixed charging point” is installed, as its name suggests, on the wall of the garage where the relevant electrical installation will take place. This device receives energy from the household or garage installation.

What types of connectors do wallboxes use?

These fixed charging points (as they are also commonly referred to) are designed to manage electrical energy using various types of connectors. It is important to remember that not all electric vehicles have the same connection to the grid. We can encounter everything from a schuko connection (standard household plug) to specific connections for certain models such as the SAE J1772, Mennekes. These connectors give us the opportunity to connect our vehicle to the grid.
