Book excerpt: The objective of this project is research, development and demonstration of innovative thermal management concepts that reduce the cell or battery weight, complexity (component count) and/or cost by at least 20%. The project addresses two issues that are common problems with current state of the art lithium ion battery packs used in vehicles; low power at cold temperatures and reduced battery life when exposed to high temperatures. Typically, battery packs are "oversized" to satisfy the two issues mentioned above. The first phase of the project was spent making a battery pack simulation model using AMEsim software. The battery pack used as a benchmark was from the Fiat 500EV. FCA and NREL provided vehicle data and cell data that allowed an accurate model to be created that matched the electrical and thermal characteristics of the actual battery pack. The second phase involved using the battery model from the first phase and evaluate different thermal management concepts. In the end, a gas injection heat pump system was chosen as the dedicated thermal system to both heat and cool the battery pack. Based on the simulation model. The heat pump system could use 50% less energy to heat the battery pack in -20°C ambient conditions, and by keeping the battery cooler at hot climates, the battery pack size could be reduced by 5% and still meet the warranty requirements. During the final phase, the actual battery pack and heat pump system were installed in a test bench at DENSO to validate the simulation results. Also during this phase, the system was moved to NREL where testing was also done to validate the results. In conclusion, the heat pump system can improve "fuel economy" (for electric vehicle) by 12% average in cold climates. Also, the battery pack size, or capacity, could be reduced 5%, or if pack size is kept constant, the pack life could be increased by two years. Finally, the total battery pack and thermal system cost could be reduced 5% only if the system is integrated with the vehicle cabin air conditioning system. The reason why we were not able to achieve the 20% reduction target is because of the natural decay of the battery cell due to the number of cycles. Perhaps newer battery chemistries that are not so sensitive to cycling would have more potential for reducing the battery size due to thermal issues.

This book was released on 2016-10-10 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research presents a method for efficiently and reproducibly comparing diverse battery thermal management concepts in an early stage of development to assist in battery system design. The basis of this method is a hardware-based thermal simulation model of a prismatic Lithium-Ion battery, called the Smart Battery Cell (SBC). By eliminating the active chemistry, enhanced reproducibility of the experimental boundary conditions and increased efficiency of the experimental trials are realized. Additionally, safety risks associated with Lithium-Ion cells are eliminated, making the use of the SBC possible with thermal management systems in an early state of developed and without costly safety infrastructure. The integration of thermocouples leaves the thermal contact surface undisturbed, allowing the SBC to be integrated into diverse thermal management systems.

This book was released on 2011 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Electrical storage technologies (i.e., batteries) play a ubiquitous role in all facets of modern technologies for applications ranging from very small to very large scale, both stationary and mobile. In the past decade, Li-ion batteries are quickly emerging as the preferred electrical energy storage technology due to the intrinsic power and energy storage density compared to older battery chemistries. All electrochemical batteries are strongly linked to their thermal state: on one hand, their electrical characteristics are strongly dependent on temperature and, on the other hand, their thermal state is a result of both their environmental temperature, but also their electrical usage due to internal heat generation. Furthermore, their life (and potentially safety) is also strongly affected by their thermal state. Li-ion batteries, due to their high electrical power capability and density tend to be used aggressively in many applications, rendering the thermal issues more acute. Finally, Li-ion battery packs (like all packs) are made of many cells interconnected in various series/parallel arrangements in tightly confined spaces. Hence, thermal management solutions need to be implemented for two primary reasons: rejecting the heat generated inside the pack to the environment to avoid high (or unsafe) temperatures leading to premature (or catastrophic) failure and providing a good thermal uniformity among all the cells so that their electrical performance (and aging) in well matched in a pack. This thesis focuses on the thermal modeling of Li-ion packs and the development of passive thermal management solutions for such packs. The thesis first provides an extensive review of the current literature on Li-ion batteries electrical and thermal modeling and current approaches for thermal management solutions of Li-ion packs. This study then focuses on a particular current application using a small Li-ion pack, namely a contractor-grade 36v cordless drill. This particular application was chosen as it encapsulates many of the features of larger automotive packs and represent and leads to an aggressive usage pattern where battery life is always an issue. This pack was experimentally studied to establish typical usage patterns and to measure the thermal and electrical state of the stock pack during such usage. The study then developed and validated a FEM computational pack model in the stock configuration. This experimentally validated models was then used as a proxy to reality to numerically investigate multiple possible configurations of passive thermal management solutions using a high thermal conductivity, Graphite-based heat spreading material to both reduce temperature non-uniformities within the pack and decrease of overall pack temperature (better heat rejection) during aggressive use. Finally, a preliminary experimental validation of one of the promising configurations of heat spreaders was investigated. The work described in this thesis clearly demonstrates that passive heat spreading technology can be very beneficial to reduce thermal stress on batteries and lead to more thermally homogenous packs. Furthermore, this study demonstrated that the investigation of such solutions can be performed with validated thermal FEM models to speed up the development of actual solution and reduce experimental prototype building. Future work will include more configurations, but also experimental investigation of battery life for both thermally managed and unmanaged packs under similar (aggressive) usage patterns. Finally, the conclusions from this study conducted on a cordless power tool are probably equally applicable to large automotive battery packs where life and costs are critical.

Available in PDF, EPUB and Kindle. Book excerpt: "Lithium ion batteries have been widely used in consumer electronics and are beginning to move to the forefront of the automotive and power grid industries. Lithium ion batteries are desirable in these applications because they are high energy density and high specific energy cells, while remaining inexpensive and lightweight. Safety is a concern in every consumer application; therefore, in order for lithium ion battery use to continue growing, advances in battery management systems are needed. Thermal management of lithium ion batteries is currently a critical issue. Applications are becoming more dependent on active liquid thermal management systems. The development of precise battery active liquid thermal management systems begins with an accurate temperature model applicable to control design. This work is focused on the development of a dynamic active liquid cooled battery cell thermal model through the coupling of a lumped energy balance and a single particle electrochemical heat generation model. A fluid channel is added to the bottom of the cell and an aluminum heat sink is added to the side of the cell. Results demonstrate that fluid temperature has more effect on the cell temperature than fluid mass flow rate. The dynamic model developed in this work has an order of 135 and; therefore, is not applicable to controller design. Linearization about an equilibrium trajectory and model order reduction via the Global Arnoldi Algorithm (GAA) is applied. Results show good agreement between the first order reduced system and the non-linear system"--Abstract, leaf iv

Available in PDF, EPUB and Kindle. Book excerpt: The unparalleled performance of lithium-ion batteries (LIBs) is driving the ongoing trend of vehicle electrification. However, expanding performance expectations continue to extend the list of "and problems" that require one battery technology to perform many roles that often conflict with each other and are impractical with existing materials. Recently, battery structure modification for internal heating has enabled rapid and efficient thermal modulation of battery performance. This structure, termed the self-heating battery (SHB), achieved restoration of power levels practical for plug-in hybrid electric vehicle batteries in -40 °C ambient conditions. What's more, when adopted for pre-heating to an elevated temperature, 10-minute extreme fast charging was enabled without sacrificing lifetime. In this dissertation, the SHB structure is studied for its applicability to electric vehicle LIBs, which conventionally meet energy density requirements for long range at the cost of stifled power performance. This serves to expand the generality of SHB application at ultra-cold temperatures (e.g., -50 °C) and, overall, the rate capability of existing and next-generation battery materials. Heating rates from ~0.5 °C/s to greater than 1 °C/s are demonstrated, quickly enabling delivery of at least ~50% of RT energy and power, as opposed to almost zero without thermal modulation. Following this, the impact of thermal modulation for improved safety and simplified thermal management is explored from a fundamental perspective. The analysis supports the development of heat-resistant batteries that rest safely in a dormant state during non-operation and are "woken up" for operation by thermal modulation for high power. This paradigm shift in battery design and operation simultaneously enables cooling simplification by enlarging the temperature difference driving heat transfer and reducing the rate of heat generation. Motivated by the broad impact of thermal modulation, the SHB design is revisited to discover an opportunity to reduce overall energy consumption by integrating the requisite switching device to share its generated heat with the battery materials for mutual thermal management. Design guidelines are established and implemented to demonstrate a prototype integrated SHB (iSHB). Through experimental and numerical investigation, iSHB heating performance and lifetime comparable to the legacy structure are elucidated. The SHB -- and now iSHB -- mark the disruption of the more than 200-year-old conventional battery structure, making a passive system active to surrender control of performance to the system designer and make previously unsolvable "and problems" tractable.
