With growing concerns over climate change due to automotive emissions, fossil fuel depletion, and the increasing price of crude oil, electric vehicles have gained more interest as a mode of transportation. Various electric vehicles have been developed in recent years, including pure electric vehicles (EVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs). One of the keen focus area in the ongoing development of EVs is their energy storage systems. Mostly lithium-ion batteries are being used as an energy storage system in EVs. Various complicated reaction occurs during charging/discharging of batteries and the thermal behavior of the batteries are coupled to these reactions. Electrochemical reactions affect the heat generation rate, and higher temperatures further increase the speed of the electrochemical reactions. Adverse operating temperatures can impact battery performance, degradation, and safety. Hence it is become very important to investigate the thermal behavior of the lithium-ion batteries. Thermal investigation of cylindrical lithium-ion batteries of different chemistry and shape factor is conducted for different charging/discharging rate and atmospheric conditions using numerical technique. The numerical technique includes the determination of surface temperature of battery by solving the energy balance equation using suitable numerical method. The accuracy of numerical techniques is validated using the experimental techniques. Thermal investigation conducted in this research can help in deciding the operating strategies of battery management system and further in designing the proper thermal management system.

We report here on the advances we have made in developing large-format Li ion polymer batteries for automotive applications. These include HEV, EREV as well as EVs. While vehicles using the high power cells were already in the market, vehicles using the high energy cells have just been introduced. Considerable research and development work over the past several years has enabled us to develop cell and pack technologies which meet the performance, life and abuse-tolerance requirements for automotive applications.

“…The experimental results show that the case of maintaining the battery pack temperature at 25 ∘ C has the best thermal performance of battery pack for all three driving traffic cycles. Payne et al [8] studied the thermal management system for the battery pack of plug-in hybrid electric vehicle (PHEV). They investigated different fin designs for the cells and the modules and also studied the effect of serpentine manifold on the pressure drops and the flow field characteristics of the pack.…”

Battery packs are critical components to electric vehicles. They are designed to last for the designed life cycles. Temperature affects the performance and life span of batteries. Maintaining stable and evenly distributed temperatures within the operating temperature range among all modules and battery cells is one of key factors to prolong the life of battery packs. This paper studied the effects of the ventilation locations of the inlets and outlets and the gaps among battery cells on the rate of heat dissipation and temperature distribution in the pack. An existing battery pack was used as a baseline design. A computational fluid dynamics model was created to analyze the temperature distribution and air flow conditions. The design intent is to keep the package changes to the minimum but with better cooling efficiency. The results show that the locations and shapes of inlets and outlets have significant impact on the battery heat dissipation. A design is proposed to minimize the temperature variation among all battery cells. The temperature difference between highest and lowest ones for the evaluated event is reduced from 6.04 ∘ C to 3.67 ∘ C with 39% improvements, and the heat dissipation rate is improved with 3.8%.
