A novel approach for Lithium-ion battery thermal management with streamline shape mini channel cooling plates

As the increasing concern of degradation or thermal runaway of lithium-ion batteries, direct cooling system on electric vehicles draws much attention and has been broadly researched. Although satisfactory energy efficiency and thermal performance can be achieved according to current appliances, in-depth discussion of system design and modeling is still necessary for providing mature applications. Herein, a comprehensive review of direct cooling system is presented, and essential components on the overall design are introduced as 4C chain (construction of the system, component modeling, cooling plate design, and coolant selection). Construction, coolant, cooling plate, and component modeling are presented independently for discussing the research progress, where detailed information is provided contributing to the selection of essential components. Moreover, the typical applications on electric vehicles of direct cooling are also investigated, and more productions are under research. Apart from system designing, the environmental fitness is also considered and the defects are summarized for system optimization.Considering to achieve future innovative application, digital twin model-based method is delivered for providing the guidance of prospective direct cooling system design, and the method enhances the potential to achieve better thermal management based on digital technologies and cloud-control platform. Based on the innovative development of cloud-controlling platform design and electronic and electrical architecture, the cloud battery controlling provides the chances for online elaborate model-based operation and precise model-based controlling strategy for novel direct cooling system.

Electric car does not supply all the electric energy, obtained from the electric network, to the wheels in the form of mechanical energy. During such a transformation, a part of this energy is lost. The article endeavours to determine the energy efficiency of selected electric car. The electric car used for measurements is not from the batch production since that is a vehicle designed at University of Zilina. The efficiency has been observed while driving under the conditions of amended methodology of New European Driving Cycle (NEDC). The measured value of electric car's efficiency is being analyzed from the energy consumption, as well as emission production, points of view.

“…Various factors, such as flow direction, number of channels, flow rate of coolant mass, and environmental temperature, were investigated in depth by the numerical simulation method. The same research group explored a series of works on the liquid cooling system assisted with minichannel cold plates, which showed a relatively high cooling efficiency [24,25]. In spite of the higher cooling effect of the liquid cooling system, several problems, including high cost, leakage, and difficult sustainment, must be overcome.…”

Lightweight power battery modules with outstanding thermal performance are urgently required given the rapid development of electric vehicles. This study proposes a composite phase change material coupled with forced convection as an integrated thermal management system (ITMS) with the aim to control the temperature’s rising tendency and maintain the temperature distribution uniformly within an appropriate range among the battery modules. The thermal behavior effects of airflow rates on the thermal management system were investigated in detail by combining experiments and numerical simulations. Comparisons were conducted between an air cooling system with an optimum flow rate and the ITMS. Experimental results revealed that the cooling effect of the ITMS was better than that of the forced cooling system at a 3 m/s airflow rate. The maximum temperature in the designed battery module was limited to 63.2°C. The maximum temperature difference was limited to 4.8°C at a 4 C discharge rate. This research indicates that the ITMS is an effective and optimized approach to control and balance the temperature among battery modules, thereby providing engineers with design optimization strategies for similar systems.
