The thermal management system of a Lithium-ion battery consisting of phasechange material (PCM) is considered in this study. The batteries are covered by a large volume of PCM. A 18650 battery is used in this numerical investigation as a case study and all achievements are implemented on it. The battery thermal management system (BTMS) parameters during discharge-restcharge-rest cycles are concerned to understand PCM behavior and battery resilience in the long run. The battery is placed adjacent to various PCMs and is charged and discharged at different rates. Results show that the paraffin wax has the worst performance, and hydrate salt and capric acid have the best performance. Furthermore, the use of polyethylene glycol as PCM improves the performance of the BTMS. Meanwhile, the composite of nano-graphite and PCM would increase a reasonable effect on the BTMS functionality.

Electric bike (E-Bike) is a bicycle driven using an electric motor and uses batteries as the energy source. It is environmentally friendly as no exhaust gas is resulted during its operation. More than one battery is normally required, being arranged in series or in parallel connection. Over limit or overloaded conditions of battery usage will reduce the lifecycle of battery, speed up its replacement and add to the maintenance cost of electric bike. This paper proposes the prevention of such degrading condition using a tool to manage the battery usage both during the charging and discharging process. The proposed electronic Battery Management System (BMS) serves to regulate, monitor, and maintain the condition of batteries to prevent any possible damage. The resulted BMS design could provide a well balancing action in a battery system consisting of 13 cells utilizing the cell-to-cell active balancing method. The test results showed that the proposed BMS could monitor the individual cell voltage with an average error of 0.032 V (0.824%), while reading the charge and discharge current with an average error of 0.04 A (6.25%), and the battery pack temperature with an average error of 1.21oC (2.9%). Additionally, the BMS could offer a functional battery pack protection system from conditions such as undervoltage, overvoltage, overheat, and overcurrent.

“…Lithium-ion batteries have become the preferred type, having a low memory effect within an appropriate temperature, voltage and current range, low self-discharge effect when not in use and high energy-to-weight ratio [3]. However, battery cells present challenges as batteries work well in a very limited temperature range and are very sensitive to high temperature gradients: exceeding such boundaries results in a drastic reduction in range and capacity, together with a shortening of battery life, in addition safety issues such as fires or explosions might also occur at high temperatures [4], [5]. Exceeding the upper temperature limit can result in electrolyte decomposition and decrease of accessible surface, leading to capacity and power fade.…”

Battery models often either fail to deliver a complete picture of the physical phenomena occurring in the cell or fail to minimize computational effort. So far, the demand for a detailed internal thermal model of battery cells with a reasonable computation time has remained unanswered. This paper addresses such question introducing a multi-domain model whose accuracy makes it suitable for thermal management system development, at a lower computational cost than competing models. The approach features an equivalent circuit parameter model with chemistrybased parameters coupled with an internal heat transfer model. The internal heat transfer model includes different sections of the cell, addressing the anisotropy and the temperature-dependence of physical properties. Material properties are partly based on manufacturer's data sheet, partly taken from literature. The development software platform enables a sensible reduction of computational effort with respect to traditional modeling techniques. Results were validated against an aggressive current at different temperatures and against current profiles obtained from two different drive cycles at different ambient temperature. The model proves to be very good in terms of accuracy.
