Differences between Wall Boxes and Charging Columns
Wall boxes are called wall-mounted electric charging stations, while ground-mounted charging stations are generically called charging stations.
The main difference between the two is that wall-boxes are mainly devices used in the private sphere, so domestic, condominium and basically residential, with access limited to those who share ownership of properties. Ground-mounted charging stations, on the other hand, can be installed in any public space: from highways to truck stops to parking lots, their use is free and allowed to a wider audience (as is the case with traditional self-service gas pumps).
TheChargeUp Europe association estimated that there are about 330,000 charging points currently installed in Europe, with 73 public infrastructures per 100,000 inhabitants and a growth rate from 2015 to 2021 of 580 percent. Finally, installed domestic units, i.e., Wall Boxes are more than double the number installed in workplaces, with most of the infrastructure in Germany, Austria, and Switzerland. By 2030, the number of columns is projected to increase tenfold.
