The Battery Management System of an Electric Vehicle is a system designed to ensure safe operation of the battery pack, and report its state to other systems. It is a distributed system, and the communication between its sub-modules is performed through wired buses. In this article, we study the opportunity to use a wireless technology named IEEE Std 802.15.4 Time Slotted Channel Hopping, a standardized protocol for low power and lossy networks. We first describe the real-world experiments we did to measure the link quality, at Medium Access Control layer, for wireless nodes placed inside an EV battery pack. Then, we propose two topology management and scheduling strategies using techniques named Linear Programming and Simple Descent, based on the results obtained in the experiments. Their goal is to achieve efficient data transfer while complying to the battery management constraints.

电动汽车电池管理系统是一个旨在确保电池组安全运行并将其状态报告给其他系统的系统。它是一个分布式系统，其子模块之间的通信是通过有线总线进行的。在本文中，我们研究了使用名为 IEEE Std 802.15.4 时隙信道跳跃的无线技术的机会，这是一种适用于低功耗和有损网络的标准化协议。我们首先描述了我们在媒体访问控制层为放置在 EV 电池组内的无线节点测量链路质量所做的实际实验。然后，基于实验中获得的结果，我们使用名为线性规划和简单下降的技术提出了两种拓扑管理和调度策略。
