The standardization for public or public-use charging points, that has been implemented in the different countries including Italy, is for sure a key passage for the deployment of the electric cars and for the system interoperability: the electric user will be able to find the charging plug always suitable to his needs!
A clear and defined legislation
- Normal power recharging points in Alternating current (AC), which means for powers less than 2 kW, must have the Mennekes – Type 2 plug (as described by the standard EN62196-2).
The geometry of the Type 2 plug and connector is the same for power ranging from 3,7 to 4,4 kW in AC, both single-phase and three-phase, the connector configuration in addition to power transfer allows the data communication towards the contacts “controlpilot” and “proximity”.
- For the recharge point defined “High power”, which means bigger than 22 kW, are provided: the Alternating Current mode always with Type 2 connector; and Direct Current (DC) with a combined connector called “Combo 2” as described in the standard EN62196-3 or CHAdeMO.
Charging times depend on two factors
An electric car charging time depends on the power available in the charging station and from the “level” or battery charge status. For example, a car with 30 kW battery capacity discharged at 70%, with a charging capacity of 11 kW will take 2 hours to fully charge.
Free of charge charging stations and against payment
Today, a lot of charging stations for electric vehicles are free. However, in the market, there are already different solutions to manage the payment for the provision of the service: users can pay directly to banknote or debit card acceptors, or they can sign their own credit card and then pay with an App.
VP Solar deals with B2B distribution of energetic systems since 1999 and resulted to be “TOP PV supplier Italy 2018” for the German EuPD research. The company offers a wide range of charging solutions and customers can download the price list in their private area.
