SEVENSTAX V2G

The Vehicle-to-grid (V2G) protocol defines the communication between vehicle and charging station. With V2G the exchange of data concerning the charging process, billing and positioning is being handled. The communication is based on the future-proof IPv6 (Internet Protocol Version 6) and according to ISO 15118 respectively DIN 70121 specification. Different cable and non cable bound systems can be used to deliver the energy as well as V2G Messages.

SEVENSTAX V2G is the world's first commercial implementation of a vehicle-to-grid communication interface for embedded systems. With our years of experience in the field of IoT devices we managed to combine SEVENSTAX V2G and SEVENSTAX TCP/IPv6 producing a unique product with an extraordinary low demand on resource together with a high level of functionality.

These are our Highlights:

  • Vehicle-to-grid (V2G) communication according to ISO 15118 and DIN 70121
  • Full V2G Application Layer Message Set

    • V2G Message Set for charging stations (Server implementation)
    • V2G Message Set for vehicles (Client implementation)
    • V2G Messages for test systems

  • Request-, Response- and Handshake-Handling
  • integrated EXI processor
  • V2G SECC Discovery Protocol (SDP)
  • Full TCP/IPv6 Stack
  • Pre defined structures for user data allows efficient implementation and processing without a complex XML parser/generator

We distinguish ourselves by our experience and provide the highest level of security:

The implementation is based on the guidelines of the "Hersteller Initiatve Software" in terms of MISRA rules, software metrics, development process and automatic testing with defined code coverage.
SEVENSTAX V2G is used by leading manufacturers of the automotive industry since years.

Flexibility one of our strength:
SEVENSTAX V2G is ready to use in vehicles and in any kind of cable or non cable based loading device. In according to that we are able to adapt our products to the individual needs of our customers, which is why we are also providing software for V2G testing devices.
