Enabling IEEE 802.15.4-2015 TSCH based Wireless Network for Electric Vehicle Battery Management

The Battery Management System (BMS) of an Electric Vehicle (EV) is a system designed to ensure safe operation of the battery pack, and reporting its state to other systems. It is a complex and distributed system. In today's BMS implementations, the communication is performed through wire buses. In this paper, we study the opportunity to use IEEE Std 802.15.4 Time Slotted Channel Hopping (TSCH), a standardized Internet of Things (IoT) approach. We first describe the real-world experiments we did to measure the link quality at Medium Access Control (MAC) layer for wireless nodes placed inside an EV battery pack. Then, we propose a topology management and TSCH scheduling strategy using Linear Programming, based on the results obtained in the experiments.
