Abstract

The battery management system (BMS) is a critical component of electric vehicles. The purpose of the BMS is to guarantee safe and reliable battery operation. To maintain the safety and reliability of the battery, state monitoring and evaluation, charge control, and cell balancing are functionalities that have been implemented in BMS. As an electrochemical product, a battery acts differently under different operational and environmental conditions. The uncertainty of a battery’s performance poses a challenge to the implementation of these functions. This paper addresses concerns for current BMSs. State evaluation of a battery, including state of charge, state of health, and state of life, is a critical task for a BMS. Through reviewing the latest methodologies for the state evaluation of batteries, the future challenges for BMSs are presented and possible solutions are proposed as well.
电动汽车电池管理系统
电池管理系统(BMS)是电动汽车的重要组成部分。BMS的目的是保证电池安全可靠的运行。为了维护电池的安全性和可靠性,BMS中实现了状态监测和评估、充电控制和电池平衡等功能。电池作为一种电化学产物,在不同的操作条件和环境条件下表现不同。电池性能的不确定性对这些功能的实现提出了挑战。本文讨论了对当前bms的关注。电池状态评估(包括充电状态、健康状态和使用状态)是BMS的一项关键任务。通过回顾电池状态评估的最新方法,提出了bms未来面临的挑战,并提出了可能的解决方案。
