An Internet Of Things (Iot)-Based Network For Dispersed And Decentralized Wireless Battery Management Systems

Conventional battery management systems (BMSs) typically adopt hierarchical master-module architectures with standard wired-communication systems for electrified vehicles. The installation of additional wiring causes critical wiring-harness issues and the centralized master-module BMS architecture may results in the failure of the entire system if the Master BMS fails. This paper proposes a new distributed wireless Internet of Things (IoT) network for dispersed and decentralized wireless battery management systems. The proposed network includes a lightweight IoT protocol, a fast and autonomous leader election algorithm for data aggregation and communication with external systems, and an IoT gateway for cloud support services. The proposed IoT network will enable battery systems to be simpler, dispersed, scalable, reliable, and cost effective.
