Charging to stop


Using an electric vehicle on a regular basis requires safe and easy-to-use charging installations. These charging infrastructures should allow the user to charge the vehicle whenever a stop is made and should not require stopping just to charge: the concept of electric vehicle charging is charging when we stop and not stopping to charge, unlike thermal vehicles!



Household socket and extension cord

This solution offers the driver the option of recharging the vehicle almost everywhere – however, it has several serious limitations.


Domestic socket and cable with a protection device

The vehicle is connected to the main power grid via household socket-outlets. Recharging is done via a single-phase or three-phase network and an installation protection device is built into the cable. This solution is particularly expensive due to the specificity of the cable.


Specific socket on a dedicated circuit

The vehicle is connected directly to the electrical network via specific socket and plug and a dedicated circuit. A control and protection function is also installed permanently in the installation. This is the only charging mode that meets the applicable standards regulating electrical installations.


Dc connection for fast recharging:

Connection system on the charging plot - the electric vehicle is connected to the main power grid through an external charger. Control and protection functions and the vehicle charging cable are installed permanently in the installation.


Take note

  • The international community has set the target of halving the emissions of greenhouse gases by 2050.
  • Modern electric vehicles are capable of up to 150 km on a single charge (20 kWh) – twenty units of electric energy.
  • Sooner or later we will all need to consider the merits of electric vehicles.
