The Middle Eastern country of Jordan may not be at the front of many people’s thoughts when queried about electric vehicles, but that may not be the case forever, going by recent moves made by the government and private sector there. In addition to electric vehicle (EV) purchases being made exempt from various taxes and fees, the Jordanian government recently (last year) entered into agreement with the Chicago-based battery-manufacturer AllCell Technologies, with the intent being, over the next decade, the development of a solar-powered electric vehicle charging network composed of 3,000 different stations. The idea is for some charging stations to be installed at gas stations, allowing for fast partial charging, and for others designed for longer charging to be installed in places where EVs will be left parked for long periods of time. As part of the $120 million deal, an app is also expected to be made available to allow users to easily locate charging stations. Here’s more via a new article from Venture Magazine: AllCell’s Jordanian CEO Said al-Hallaj predicts his agreement with the government, combined with the tax and fee exemption, will result in roughly 50,000 to 100,000 of Jordan’s 1 million-plus cars becoming electric within 5 to 7 years. …The government was never going to be able to introduce the same electric car subsidies or grants that have been introduced in some wealthy Western countries. So it came up with the next best thing. “If you import an electric car you are exempt from all charges and taxes – that’s almost double the price of the car. You’re making electric cars more competitive than gasoline cars,” al-Hallaj said. …But before you dash out to buy an EV, it’s important to note that regulations still have to be put in place before the project can advance. There’s already a law in place that governs the transportation, or ‘wheeling’, of renewable energy along transmission lines. But AllCell is still waiting on the government to create further legislation that will oversee its business model, which includes a 30 MW solar farm that will feed into the grid to cover the electricity being sucked up by the proposed network of charging stations. “There are laws for renewable energy wheeling, but in our case, we’re selling to consumers and offering them a service that needs to be regulated,” al-Hallaj continued. “We’re waiting to clarify and get proper government agencies to draft and implement the right rules and regulations that cover this concept.” It’s assumed that these will be offered up relatively soon, according to al-Hallaj. As it stands right now, there’s only one station operational (at the King Hussein Business Park), but there are supposed to be another 10 stations launched within the year.

Materials containing phase change and graphite composites are very attractive materials for energy storage and thermal management applications because of their high thermal conductivity and heat storage characteristics. Mostly, these composites are currently used in thermal management of lithium-ion batteries to regulate the battery temperature and protect the battery from undesirable thermal runaway and also it can be used in other thermal energy storage applications. Several samples with expanded graphite impregnated with phase change material composites such as paraffin wax were tested in quasi-static stress-strain compression tests. To provide these composites with flexibility and compressibility, a special silicon polymer added to the phase change material-expanded graphite composite resulted in a new phase change material with expanded graphite and polymer composite; for which several samples of this composite were tested as well. The compression tests were performed using an Instron 3300R floor model universal testing system at a constant platen speed of 52 mm/min. All tests were conducted at room temperature and they were compressed up to failure. All phase change material-expanded graphite composite samples were tested in-plane and through-plane relative to the expanded graphite compaction directions. Both phase change material-expanded graphite composite samples in in-plane and through-plane directions showed distinct and unique mechanical and thermal characteristic responses. Compression stress-strain tests for all samples were modeled using a combined constitutive viscoelastic polymeric foam model equation based on Kelvin and Maxwell models. In this research, the Maxwell-Kelvin viscoelastic model was used to calibrate the compression tests for expanded graphite, phase change material-expanded graphite, and phase change material with expanded graphite and polymer composites. It was found that ductility and viscous characteristics of the model are due to the presence of expanded graphite whereas brittleness characteristics are due to the presence of phase change material. The polymeric foam model equation is a powerful tool for designing new energy storage composites with targeted mechanical and thermal characteristics such as yield strength, Young's modulus, thermal conductivity, and latent heat. From curve fitting of the experimental tests of phase change material-expanded graphite composites with the viscoelastic model, several mechanical properties such as elastic and viscous coefficients were computed. © The Author(s) 2015.

The growing demand for lithium ion batteries with long lifetime and warranty presents significant challenges for battery pack manufacturers to sufficiently understand cell ageing while keeping testing and validation costs low. To keep up with the rapid deployment of new cell types, appropriate modeling can be used to extrapolate limited-duration empirical results. We have implemented a semi-empirical modeling approach for predicting capacity fade under various operating conditions, using physicsbased degradation mechanisms that provide a good fit to experimental data. Good agreement between the model and empirical results is demonstrated for two state-of-the-art 18650 cell types. The major improvement of this work over other approaches is that it minimizes the testing necessary to validate the unique capacity fade of each new cell type, allowing pack manufacturers to rapidly and accurately down-select the best candidate cells for specific applications. © The Electrochemical Society.

The use of phase change materials (PCMs) in thermal storage is not a new concept, but engineers are continually finding new ways to utilize them in a wide range of applications. A PCM takes advantage of high latent heat in the phase change process to store large amounts of heat while undergoing only a small change in temperature. This property makes PCMs suitable for thermal storage purposes in a wide range of engineering applications. Due to the nature of these applications, it is vital to have a precise knowledge of the thermal characteristics of any PCM. Unfortunately, due to the low thermal conductivities and high latent heats found in PCMs, current measuring tools such as differential scanning calorimetry, provide inconsistent results. This paper conjectures that these errors come from the effects of low thermal diffusivity samples as well as improper data analysis methods. © 2010 Akadémiai Kiadó, Budapest, Hungary.

This paper proposes the design of an online temperature estimation technique for a Li-ion battery pack that utilizes phase change composite (PCC™) for thermal management. The phase change composite allows heat absorption and distribution, enabling lightweight and compact packs with extended cycle-life and safety. A coupled electro-thermal model has been developed for the cylindrical 18650 Li-ion cells, from which the cell heat generation is calculated. The electrical equivalent circuit comprises three RC pairs, where their values are functions of temperature and state of charge. An analytical thermal model is developed for the battery pack, considering the phase change composite and cells, which allows online temperature estimation all over the battery pack. © 2016 IEEE.

Abstract A lumped (0-D) numerical model has been developed for simulating the thermal response of a lithium-ion battery pack with a phase-change composite (PCC™) thermal management system. A small 10s4p battery pack utilizing PCC material was constructed and subjected to discharge at various C-rates in order to validate the lumped model. The 18650 size Li-ion cells used in the pack were electrically characterized to determine their heat generation, and various PCC materials were thermally characterized to determine their apparent specific heat as a function of temperature. Additionally, a 2-D FEA thermal model was constructed to help understand the magnitude of spatial temperature variation in the pack, and to understand the limitations of the lumped model. Overall, good agreement is seen between experimentally measured pack temperatures and the 0-D model, and the 2-D FEA model predicts minimal spatial temperature variation for PCC-based packs at C-rates of 1C and below. © 2015 Elsevier B.V.
