“…Much of the literature has therefore focused on 3D thermal modelling of battery packs [2, [7][8][9][10] and designing thermal management systems gradients in the solid phase, which is linked to particle fracturing and hence capacity and power fade through the isolation of electrode material, and contact loss, respectively [18,19].…”

KeywordsLithium-ion battery; external pressure; capacity fade; power fade; cell ageing; cycle life AbstractIn application, lithium-ion pouch-format cells undergo expansion during cycling. To prevent contact loss between battery pack components and delamination and deformation during battery operation, compressive pressure is applied to cells in automotive battery modules/packs by way of rigid cell housing within the modules. In this paper, the impact of such compressive pressure on battery degradation is studied. Samples of commercial, 15 Ah LiNiMnCoO2 /Graphite electrode pouch-type cells were cycled 1200 times under atmospheric, 5psi and 15 psi compressive loads. After 1200 cycles, the capacity fade for 0, 5 and 15psi loads was11.0 %, 8.8 % and 8.4 %, respectively; the corresponding power fade was found to be 7.5 %, 39 % and 18 %, respectively, indicating power fade peaks between 0 and 15psi. This contrasting behaviour is related to the wettability increase and separator creep within the cell after compressive load is applied. The opposing capacity fade and power fade results require consideration from automotive battery engineers at the design stage of modules and packs. In addition to capacity fade and power fade results, the study identified the evolution of compressive pressures over multiple cycles, showing that pressure increases with cycling.

Abstract-Demand-side management, together with the integration of distributed energy generation and storage, are considered increasingly essential elements for implementing the smart grid concept and balancing massive energy production from renewable sources. We focus on a smart grid in which the demand-side comprises traditional users as well as users owning some kind of distributed energy sources and/or energy storage devices. By means of a day-ahead optimization process regulated by an independent central unit, the latter users intend to reduce their monetary energy expense by producing or storing energy rather than just purchasing their energy needs from the grid. In this paper, we formulate the resulting grid optimization problem as a noncooperative game and analyze the existence of optimal strategies. Furthermore, we present a distributed algorithm to be run on the users' smart meters, which provides the optimal production and/or storage strategies, while preserving the privacy of the users and minimizing the required signaling with the central unit. Finally, the proposed day-ahead optimization is tested in a realistic situation.

“…It is used fundamentally to preserve the temperature of battery cells in a pack at an optimal range [39][40][41][42][43]. It helps to enhance the lifetime while ensuring safe and secure operation of the battery pack [44][45][46][47]. It is therefore inevitable that BTMS is typically associated with the process of retaining the operational temperature at an optimal level through keeping the temperature gradient within a relatively narrow range [48].…”

Abstract:The prevailing standards and scientific literature offer a wide range of options for the construction of a battery thermal management system (BTMS). The design of an innovative yet well-functioning BTMS requires strict supervision, quality audit and continuous improvement of the whole process. It must address all the current quality and safety (Q&S) standards. In this review article, an effective battery thermal management is sought considering the existing battery Q&S standards and scientific literature. The article contains a broad overview of the current existing standards and literature on a generic compliant BTMS. The aim is to assist in the design of a novel compatible BTMS. Additionally, the article delivers a set of recommendations to make an effective BTMS.
