European standard for charging

European standard for charging

A conference organized by Scame Parre was held in Parre, in the Province of Bergamo, on the problem of the standardization of the charging system for electric vehicles throughout Europe.
Below is the information provided by Scame Parre with the respective illustrative photos.

On March 17, 2010 SCAME, SCHNEIDER, LEGRAND announced through the web and specialized magazines the creation of the EV PLUG ALLIANCE association based in Rue de l’Amiral Hamelin, 17 – 75016 Paris

The purpose of the alliance:

– Promote the 3C type connector as a European standard for the charging infrastructure as it guarantees the highest level of protection thanks to the presence of shutters (insulating screens) that protect against any accidental contact with live parts.

– Promote mode 3 charging mode (IEC 61851-1)

– Create a recognized brand that guarantees a high quality standard of products thanks to a procedure

test standard that also verifies the interoperability of the various EV PLUG ALLIANCE products.

The alliance has no commercial purposes but only proposes a single European standard for infrastructure
Create an ECO-SYSTEM with high quality standards for a European charging infrastructure (20 associated in March 2011)
Vision for a standard connector for the charging infrastructure

Which plug for the electric vehicle?

The Mennekes type 2 connector conflicts with the national regulations of many European countries which require shutters if “untrained” people use electrical connectors.
The question is not to choose a connector but to choose a charging system
In fact, the car does not connect directly to the infrastructure, but a connection cable is required
So we have the flexibility to choose a cable with 2 different connectors on both sides (e.g. the USB connector is a concrete example of how to solve the problem)

So the proposal is:

The solution:

Vehicle side from 3.7 kW (16A) up to 43 kW AC

The choice is of the car manufacturers: Type 2 (Mennekes) – Type 1 (YAZAKI)

The solution:

Infrastructure side up to 24 kW
When the cable is not fixed to the wall, choose type 3 EV Plug Alliance, with a single dimension for single / three-phase 16 or 32 A and with protection shutter. (over 24 kW, which will never be the case in the home, the cable can always be attached to the infrastructure)
Vision for a standard connector for the charging infrastructure

Problems are solved:

• One cable for all European cars: one standard as required

• Type 2, Type1 on the vehicle side (many manufacturers have already completed the design of the car)

• Type 3 on the infrastructure side, guarantees a solution that perfectly complies with national regulations throughout Europe and optimizes use in homes

• Perfectly in line with the IEC standards in preparation (IEC 62196-1-2) Furthermore, flexibility is guaranteed:

• Allowing the evolution of the vehicle-side connector according to the needs of manufacturers without having to redo the infrastructure (e.g. if in the future there will be a connector also suitable for the vehicle-side DC)

• Since the same connector is not required on both sides, it is possible to choose a different connector on small cars (scooters) (eg 10 A): the cable for these vehicles can be type 3 on the wall side (this will guarantee the connection of small vehicles on the charging infrastructure)
