The lithium-ion battery pack in hybrid electric vehicles is an important energy storage device that requires proper thermal management. A considerable amount of heat is generated by the battery cells owing to their internal resistance during charging and discharging, especially for peak vehicle loads. This study focuses on developing a smart controlled thermal management solution in which a vapor compression system is integrated. A lumped-parameter cylindrical battery thermal model is developed with a Kalman observer to estimate the transient changes in the temperatures of the battery surface, the battery core, and the cooling air flowing around the cells. For the first time, the optimal cooling air temperature of the battery is investigated using optimal control theory. A model predictive controller is then introduced to regulate the refrigerant compressor and to track the ideal cooling air temperature. In a case study, the power consumption of the thermal management system and the behavior of the internal temperature of the battery are investigated under an urban assault cycle. For various operation configurations and conditions, the numerical results demonstrate that the peak error of the core temperature of the battery can be tracked within 0.25°C of the target value and the energy consumption of the cooling system can be reduced by up to 58%.

“…Both inlet port and outlet port are located at the front or on the same side to minimize the variation of the flow rates in individual coolant flow channels. 4,10 The coolant channels and ducts can be configured to reduce total pressure loss at the inlet and outlet ducts and the manifold and maintain substantially uniform coolant flow rate and heat transfer rate across the module and within individual battery cells. As a result, the operational temperature variation in the battery cells across the battery module from front to back, and within each battery cell from top to bottom can be reduced.…”

This paper describes the development of a liquid cooling system of battery module with lithium-ion prismatic metal can battery cells that can be used in hybrid electric vehicles (HEV). Initially, a design concept of a liquid cooled battery module is selected based on the functional requirements associated with maximum battery cell temperature rise, temperature uniformity across the battery module, temperature uniformity within each individual lithium-ion prismatic battery cell, and total pressure loss of the liquid cooling system. A three-dimensional battery module thermal model and an analytical optimization approach are developed for selected design concept of the liquid cooled battery module. Finally, by performing analytical optimization study to examine the effects of geometries of the inlet duct, manifold, and the outlet duct on battery module thermal behavior and total pressure loss of cooling system, the optimal design concept of liquid-cooled battery module is identified to maximize its durability and driving range.

“…The Latin Hypercube algorithm allows a regular sampling throughout the design space to attain the most of information out of the points analysed with the minimum number of design evaluations. LHC sampling schemes have been extensively used in DoE based metamodel development initiatives as evident from the studies (Awad et al, 2005;Boussouf, 2011;do Rego et al, 2006;Gao et al, 2012;Scarlat et al, 2002;Sun et al, 2011;Wang et al, 2004;Gu et al, 2012) to name a few.…”
