An evaluation of the environmental impact manufacturing an oxide all-solid-state lithium battery with economic cell design.

Current commercial battery management systems (BMSs) do not provide adequate information in real time to mitigate issues of battery cells such as thermal runway. This paper explores and evaluates the integration of fiber optic Bragg grating (FBG) sensors inside lithium-ion battery (LiB) coin cells. Strain and internal and external temperatures were recorded using FBG sensors, and the battery ce...

Fungi have a significant impact on the economics of paper making and the end use of paper and products employing paper related components. Paper on a practical basis is a derivative of wood, and fungi that possess cellulose-degrading enzymes can directly impact the value and utility of various types of products. Fungi further have a negative economic impact on the pulp produced during paper man...

Resistive companion (RC) modeling is an easy-to-use approach for electric circuit simulations. With a RC numerical solver, simulations of complex electric systems can be achieved based on RC models. In this study, the construction of RC battery models is investigated. A general battery model and a nickel±metal hydride cell model have been built. Simulations of RC battery models on virtual test ...

In the process of battery system design and operation, accurate battery modelling is a key factor. Generally speaking, the electric characteristics of a given battery cell are necessary for a designer to build an equivalent circuit model. The equivalent circuit design entails the creation of both the sizing of components used in the circuit and the topology. So, it is very hard to build an accu...

Batteries in a fuel-cell power system are essential to providing the additional power during the sharp load-transients. This necessitates a power-electronics subsystem (PES), which controls the energy flow between the fuel-cell stack, the battery, and the application load during the transient and in the steady states. In this paper, a distributed PES (comprising a multimodule dc-dc boost conver...

Reducing the overall vehicle weight is an efficient, system-level approach to increase the drive range of electric vehicle, for which structural parts in auto-framemay be replaced by battery modules. Such battery modules must be structurally functional, e.g., energy absorbing, while the battery cells are not necessarily loading–carrying. We designed and tested a butterfly-shaped battery module ...

This paper presents an effective technique to monitor and predict the open circuit voltage (OCV) for lead-acid battery cells. The underlying principal of the technique described in this paper employs one simple equation to predict the equilibrated cell voltage after a small rest period. The technique was tested and analyzed using results obtained from experiments conducted at the Yuasa Battery ...
