电动汽车锂离子电池数据驱动故障溯源

Lithium-ion battery failure is the main cause of electric vehicle fire accidents. In this article, we propose a fault analysis framework for Big Data-driven fault trace extraction based on the whole-life-cycle charging data of onboard lithium-ion batteries. First, battery voltage features strongly correlated with faults are mined and automatically selected by a random forest algorithm from the las...
