Electric vehicles (EVs) are becoming widely used for its low energy consumption and low pollution. An accurate estimation of available capacity for Li-ion batteries has an important utility significance to optimize its performance in the applications of EVs. The Peukert equation is applied to estimate the available capacity of batteries. However, the fact that the available capacity of Li-ion batteries is dependent on battery temperatures can result in errors while using the Peukert equation. To address this problem, this paper proposes an extended Peukert equation to include temperature effect. This method considers battery temperature as an input variable into the Peukert equation. Experiments based on Li-ion batteries are carried out under various current and temperatures. The comparison of the estimated and the actual available capacity indicates that the proposed algorithm can provide a reliable and accurate estimation of the available capacity for Li-ion batteries.

Vehicles running on fossil fuel are creating a threat to the environment by emitting pollutants such as carbon monoxide, carbon dioxide and sulfur and nitrogen oxides into the environment. Electric vehicles and hybrid electric vehicles provide a perennial solution to this problem and since the utilization of renewables for charging, the market is on verge of electric vehicle revolution. Electric propulsion systems can also be used in heavy transport vehicles, thus transitioning them to electric. This paper puts forth an overview of the electric vehicles for transportation of masses and freight across the globe and emphasis on the battery charging infrastructures. Recent trends and advancements in electric vehicle batteries are discussed briefly, along with sustainability in Li-ion batteries and its materials; moreover, a comparative study of different electric vehicles available in the Indian market is done. Similarly, the incentives offered by government, challenges faced by these vehicles and future development areas are conversed at the end of the paper.

This paper studies the use of bipolar-particles-electrodes in the decolorization of dyeing effluents. Treatment of highly colored solutions of various soluble dyes (such as direct, reactive, cationic or acid dyes) and also samples of dyeing effluents gave rise to an almost colorless transparent liquid, with removal of CODcr and BOD5 being as high as over 80%. The method is characterized by its high efficiency, low energy consumption and long performance life. A discussion of the underlying principle is given.

Recent market studies show that the market for remote monitoring devices of different medical parameters will grow exponentially. Globally, more than 4 million individuals will be monitored remotely from the perspective of different health parameters by 2023. Of particular importance is the way of remote transmission of the information acquired from the medical sensors. At this time, there are several methods such as Bluetooth, WI-FI, or other wireless communication interfaces. Recently, the communication based on LoRa (Long Range) technology has had an explosive development that allows the transmission of information over long distances with low energy consumption. The implementation of the IoT (Internet of Things) applications using LoRa devices based on open Long Range Wide-Area Network (LoRaWAN) protocol for long distances with low energy consumption can also be used in the medical field. Therefore, in this paper, we proposed and developed a long-distance communication architecture for medical devices based on the LoRaWAN protocol that allows data communications over a distance of more than 10 km.
