Abstract

Operational data of lithium-ion batteries from battery electric vehicles can be logged and used to model lithium-ion battery aging, i.e., the state of health. Here, we discuss future State of Health definitions, the use of data from battery production beyond production, the logging & aggregation of operational data and challenges of the State of Health in automotive applications. Our suggestions could improve data transfer efficiency and data storage costs.

摘要

来自电池电动汽车的锂离子电池运行数据可以被记录下来，并用于对锂离子电池老化（即健康状态）进行建模。在此，我们讨论未来健康状态的定义、生产以外阶段电池生产数据的使用、运行数据的记录与汇总以及汽车应用中健康状态面临的挑战。我们的建议可以提高数据传输效率和数据存储成本。
