Workshop: Embedded networking in light-electric vehicles (LEV)

Most of the LEVs are using embedded CAN-based networks. Currently, the compatibility and interoperability of in-vehicle devices is rather low, because higher-layer protocols and device profiles are not standardized. Although, there are different CANopen-based solutions on the market, the integration of devices is a challenging and time-consuming task.

Of course, CiA members have developed the CiA 454 CANopen application profile for energy management systems series. Some of the parts of this series has been withdrawn, because the content has been moved into the IEC/TS (technical specification) 61851-3-4:2023. It applies to CANopen communication for the conductive transfer of electric power between the supply network and an LEV or a removable rechargeable energy storage system (RESS) or on-board RESS. The energy management system (EMS) for control of power transfer between battery systems and voltage converter units (VCU) provides the communication for all devices that can take part in the energy management control.

These puzzle pieces are nice to have, but they do not cover all entities of an embedded LEV network. Especially, a company-independent LEV diagnostic interface is not specified. There are also some other functional elements missing.

Therefore, CiA likes to invite you to a workshop discussion these issues. The workshop provides the opportunity to present your ideas and solutions to overcome the current situation.

The workshop is scheduled on March 13 (Friday) from 9:00 to 13:00, one day after the Embedded World tradeshow. It takes place in Nuremberg (Germany). Rotax Bike Technology (CH) will present its CANopen-based FIT 2.0 approach and CiA will provide an overview on the released related IEC and CiA documents.
