Continuous monitoring of temperature distribution in lithium-ion (Li-ion) batteries is critical in preventing rapid degradation, mismatch in cell capacity, and potentially thermal runaway. A model based on virtual thermal sensor (VTS) for automotive grade Li-ion batteries is presented in this paper. This model, using a small number of physical sensors, is able to estimate temperature distribution...
Thermal modeling of the battery is an effective way to understand how the design and operating variables affect the thermal behavior of the battery during its operation. This paper presents a method for modeling the three-dimensional electrical and thermal behavior of a high energy lithium iron phosphate (LiFePO4) battery cell. The model takes into account the irreversible resistive heat and reversible...
Continuous monitoring of temperature distribution for Lithium-ion (Li-ion) batteries is critical to prevent them from rapid degradation, mismatch in cell capacity, and potentially thermal runaway. Existing techniques for estimating temperature profile of batteries are either computationally inefficient or costly; the concept of state-space based multi-nodes thermal model is introduced in this paper...
In order to cut down air-condition energy consumption in the communication room and reduce the heat island effect partially, through the use of CFD (computational fluid dynamics), we have a study on airflow characteristics in communication engine-room. On the basis of established mathematical and physical equation about airflow characteristics, we try to get the numerical solution, and analyze the...
