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. 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.

电池数据的未来和汽车应用中锂离子电池的健康状况。
电池电动汽车锂离子电池的运行数据可被记录并用于锂离子电池老化建模,即健康状态建模。在此,我们将讨论 "健康状态 "的未来定义、电池生产数据在生产之外的使用、记录与amp、运行数据的汇总以及 "健康状态 "在汽车应用中面临的挑战。我们的建议可以提高数据传输效率,降低数据存储成本。可以记录电动汽车锂离子电池的运行数据,并利用这些数据建立锂离子电池老化模型,即健康状态模型。在此,我们将讨论 "健康状况 "的未来定义、电池生产数据在生产之外的使用、记录和amp、运行数据的汇总以及 "健康状况 "在汽车应用中面临的挑战。我们的建议可以提高数据传输效率,降低数据存储成本。
