CharIN Testival 2019

October 30-31, 2019 | ElaadNL (Arnhem, The Netherlands)

Electric Vehicle (EV) Charging Communication in the form of the Combined Charging System (CCS) is a core enabling technology for fast charging EVs as well as for future Smart Grid integration. Its interoperability is key for user acceptance and economies of scale, but at the same time a major technical challenge due to the huge number of different implementations, individual use cases and requirements on a diverse global market.

The CharIN Testival embraces this challenge and brings together companies from the Smart Charging community and their technology experts to conduct conformance & interoperability tests for Electric Vehicles and Charging Infrastructures or respective Electronic Control Units (ECUs) and Communication Controllers.

Rather than talking about interoperability, this is a hands-on event digging deep into implementing, supporting and testing interoperability. By participating at this event your company or organization benefits through unprecedented networking with international technology experts in smart charging communication.

ISO/IEC 15118 communication standard for charging of electric vehicles

The charging communication protocol defines the vehicle to charging station communication.

Within the Combined Charging System (CCS) it is agreed to use this to enable interoperable charging as an important component in ecosystem. It provides additional charging features and ensures long time invest protection for all market participants. Features like Plug & Charge and Value Add services will make charging as convenient as possible.

With ISO 15118 also bi-directional this means charging/discharging of electric vehicles (Smart Charging) is possible. Thus, the technical framework for different variations of integrating electric vehicles in intelligent grid networks has been developed. For the required hardware a powerline communication module is needed (PLC) as well as a TCP/IP protocol stack.

The international standard series contains the following parts:

  • Part 1: General information and use-case definition
  • Part 2: Network and application protocol requirements
  • Part 3: Physical and data link layer requirements
  • Part 4: Network and application protocol conformance test
  • Part 5: Physical layer and data link layer conformance test
  • Part 8: Physical layer and data link layer requirements for wireless communication
