CANOpen Communication of a 16.4kWh Li-ion Battery Energy Storage System for Nanogrids in Energy Community Framework

This paper proposes a feasible solution for implementing the CANOpen communication between the controller of a nanogrid and a 16.4kWh Li-ion battery storage system in an Energy Communities framework. The proposed solution has been implemented and tested in laboratory, programming a C2000 32bit microcontroller by Texas Instrument mounted on a F28379D devkit. The laboratory results clearly demonstrate that the microcontroller properly communicates with the battery management system. In particular, this paper reports the dataframes encoding, including heartbeats, process data objects, keep alive check and the warning/error tests.
