降额是指设备在低于其最大能力的情况下运行，以确保安全、减少退化并避免系统关闭。本文综述了电动汽车锂离子电池常用的降额策略。它描述了基于电池温度、充电状态、内阻、目标充电电压、电压限值和临界误差的降额因素的实际使用和实施。它汇集了来自各个专业领域的观点和概念，例如安全，热管理，建模或诊断，以便读者能够理解为什么降额很重要以及具体的挑战是什么。混合动力和全电动汽车的仿真，以显示相对简单的降额策略审查的有效性，并帮助读者获得更好的理解降额如何影响车辆的性能。
Derating is the operation of a device at less than its maximum capability in order to ensure safety, reduce degradation, and avoid system shutdown. This paper reviews common derating strategies for lithium-ion batteries in electric vehicles. It describes practical use and implementation of derating factors based on battery temperature, state-of-charge, internal resistance, target charge voltage, voltage limits and critical errors. It brings together perspectives and concepts from various areas of expertise, e.g. safety, thermal management, modelling, or diagnosis, so that the reader can understand why derating is important and what are the particular challenges. Simulations on hybrid and full electric vehicles are provided, to show the effectiveness of the relatively simple derating strategies reviewed, and to help the reader gain a better understanding of how derating influences the vehicle's performance.
