锂电池组动态热模型在混合动力汽车中的应用
Research of dynamic thermal model for lithium battery pack used in hybrid electrical vehicle
摘要
Abstract
The thermal model was a crucial part for Battery Thermal Management (BTM) of hybrid electrical vehicle.The performance and life span of lithium battery pack under serial connection and parallel connection were focused.A control-oriented dynamic thermal model for battery pack was presented.The main feature of this model was the actual working temperature that could be estimated based on environmental temperature,operation load,cooling method and initial State of Charge (SOC).The 18650-type lithium batteries were used to form the battery pack with 3 serial connection/3 parallel connection and 3 parallel connection/3 serial connection,respectively.The temperature distribution curve was obtained after charge/discharge experiments.The results show that the new model has the better estimation precision and can greatly meet the design requirement for BTM hybrid electrical vehicle.关键词
