Mode 3 Electric Vehicle conductive charging equipment in accordance with IEC 61851-1 requirements

Mode 3 Electric Vehicle conductive charging equipment in accordance with IEC 61851-1 requirements
To integrate Mode 3 communication into the electrical car charging equipment of eNovates, Bausch Datacom developed the eVcc: mode 3 charging means that the device controlling the PWM communication (Pulse Width Modulation) is built inside the charging station or pole and not just inside the charging cable. It means that the Mode 3 communication charging relates connection of the Electrical Vehicle to the AC supply network (mains) utilizing dedicated electric vehicle supply equipment where the control pilot function extends to the control equipment inside the charging device itself.

 

For 'Mode 3' charging of electric vehicles, Bausch Datacom designed the eVCC or 'Electrical Vehicle Charge Control Unit' in accordance with IEC 61851-1 requirements.

It means that the Mode 3 communication charging relates connection of the Electrical Vehicle to the AC supply network (mains) utilizing dedicated electric vehicle supply equipment where the control pilot function extends to the control equipment inside the charging device itself. So verifying the CP & PP signals - Control Pilot (1) and Proximity (2) - , PWM communication and controlling PWM output, RCD, over current protection, switch-off etc...are now mandatory components of the charging station itself and this functionality is provided by the eVcc of Bausch Datacom: the Bausch eVcc, built inside the different charging poles of Enovates, provides complete control of the charging process; charging does not start until all safety prompts clearly meet the IEC 61851-1 specifications and until the maximum admissible charging current is transmitted.

 

(1) Proximity contact or plug present contact for defining the ampacity of the charging cable and for activating the engine immobilizer.
(2) CP or Control Pilot, name for the connector contact/cable used to transmit the communication information.

 

Unique cooperation between eNovates - producer of electrical charging units - and Bausch Datacom - automation -.

 

Since 2010 Bausch Datacom provides for communication and control of the innovative electric car charging infrastructure of Belgian manufacturer eNovates and provider Blue Corner. The unique cooperation started with the engineering of a terminal unit (eRTU) that provides the control and communication of the electrical charging units. The charging unit is constantly in contact with a central (server) host system. This is revolutionary because eNovates wants to take into account the 'SMART GRID' theme of a mass production of electric cars and their impact on the electrical net.In 2011 Bausch Datacom was asked by eNovates to design a ‘Mode 3’ charging device in accordance with IEC 61851-1 requirements (Electric vehicle conductive charging system – Part 1), the so-called “Electrical Vehicle Charge Control Unit (eVcc).

If you are interested in the eVCC and eRTU products please contact sales@bausch.be, Bart.Vereecke@enovates.com or give us a call at (0032)16461288.
