Definitions

• the present invention relates to a vehicle for distributed electric charging of electric car batteries and a related management system.
• Such movable charging means consist of vans equipped with pre charged batteries that can be connected to an electric vehicle to charge it.
• movable charging means consist of vans equipped with pre charged batteries that can be connected to an electric vehicle to charge it.
