Thermal management especially cooling plays an important role in power battery modules for electric vehicles. In order to comprehensively understand the heat transfer characteristics of air cooling system, the air cooling numerical simulation battery models for cylindrical lithium-ion power battery pack were established in this paper, and a detailed parametric investigation was undertaken to st...

In most of the Automotive Air Conditioning Systems (AACSs) though the compressor is powered by the car engine, the evaporator blower and the condenser fan are run by a 12-volt DC battery which is powered by an alternator. Any fault in the alternator, drops the battery output voltage. Owing to this, a stationary test rig for an AACS is developed with all actual automotive components. A continuou...

Paper-based batteries are an alternative to traditional batteries due to their low cost, portability, and simplicity to operate. In the present work, we demonstrate an improved and inexpensive paper-based aluminum-air battery employing KOH as the electrolyte with sufficient energy to power small devices. The dimensions of the device, electrode size, and electrolyte concentration were optimized ...

If battery packs for electric vehicles (EVs) and hybrid electric vehicles (HEVs) are to operate effectively in all climates, thermal management of the packs is essential. In this paper, we will review a systematic approach for designing and evaluating battery pack thermal management systems. A thermal management system using air as the heat transfer medium is less complicated than a system usin...

In electric vehicles, the battery pack is one of the most important components that strongly influence the system performance. The battery thermal management system (BTMS) is critical to remove the heat generated by the battery pack, which guarantees the appropriate working temperature for the battery pack. Air cooling is one of the most commonly-used solutions among various battery thermal man...

Purpose – The paper’s aim is to show the development of materials and methods which allow freeform fabrication of macroscopic Zn-air electrochemical batteries. Freedom of geometric design may allow for new possibilities in performance optimization. Design/methodology/approach – The authors have formulated battery materials which are compatible with solid freeform fabrication (SFF) while retaini...

The goal of this study was to develop a rechargeable aluminum–air battery with high capacity and longterm durability in charge–discharge electrochemical reactions. We used aluminum terephthalate as a metal–organic framework (MOF) material for the air cathode and 1-ethyl-3-methylimidazolium chloride as an ionic liquid electrolyte. When we used aluminum terephthalate as an air cathode material, t...

With the surge of interest in miniaturized implanted medical devices (IMDs), implantable power sources with small dimensions and biocompatibility are in high demand. Implanted battery/supercapacitor devices are commonly packaged within a case that occupies a large volume, making miniaturization difficult. In this study, we demonstrate a polymer electrolyte-enabled biocompatible magnesium-air ba...
