Advances in electro-thermal coupling models for energy storage Li-ion battery
摘要
Abstract
The high-precision battery model was the key to improve the efficiency of battery management system,which was of great significance to realize battery system state assessment,life prediction and healthy operation.The performance of Li-ion battery,temperature non-uniform characteristics and Li-ion battery electro-thermal coupling model construction methods and problems were summarized.There was a lack of research on the electro-thermal interaction mechanism for the whole life cycle of large-scale energy storage battery under complex structure and environmental factors.Battery thermal analysis models based on empirical equations and the internal mechanism of the battery had problems such as slow calculation speed,low accuracy and poor generalizability.Data-driven-based modelling was a more efficient method for constructing battery thermal models.At the battery pack level,most models were constructed based on series-parallel connection and battery state parameters,which couldn't accurately simulate the dynamic characteristics of the battery under the non-uniform conditions of current and ambient temperature.Based on the complex structure of the energy storage battery system and the environmental characteristics,it had became the next research direction to improve the calculation speed and accuracy of the model.关键词
