Experimental validation of a new power line communication system for battery management

Abstract

A new Power Line Communication (PLC) solution over a DC powerline is presented for remote management of batteries. This solution rely on the well known Controller Area Network (CAN) protocol and is designed to be directly compatible with existing CAN controllers. The presented PLC-CAN system is a low complexity and low cost solution suitable for short and low power DC bus used in small scale autonomous systems. Simulations of the communication channel over the frequency range [0.5 -10] MHz are conducted to validate the concept's feasibility. Experimental measurements on prototypes are then presented and show achievable data rates of 116 kbit/s.
