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 standardized Internet of Things (IoT) protocols for these communications and in such an environment, and IEEE Std 802.15.4-2015 Time Slotted Channel Hopping (TSCH) in particular. 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.
