1. 1. State of Health measuring of NiMH batteries using simple electronic components.

   University essay from Linköpings universitet/Fordonssystem

   Author : Linus Classon; [2024]
   Keywords : SoH; NiMH; State of Health; Batteries;

   Abstract : The possibility of measuring the state of health of a NiMH battery without doing it in a lab is evaluated, the goal was to see if it was possible to perceive any differences between batteries of different states of health and whether it’s worth further exploring this solution in a more detailed manner. In order to try and extract and analyze the state of health of the batteries a series of tests consisting of discharging batteries at different lengths of times and different resistive loads were made, the voltage of the batteries being captured by a multimeter.

3. 2. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

   University essay from Umeå universitet/Institutionen för fysik

   Author : Franz Wikner; [2024]
   Keywords : Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

   Abstract : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

   Abstract : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. READ MORE

6. 5. Strategies for enhancing the circularity of Lithium-ion Batteries.

   University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

   Author : Tanveer Ahmad Malik; [2023]
   Keywords : EVs battery; Lithium-ion battery; Circularity; SWOT analysis; recycling of Li-ion batteries; Second life of battery;

   Abstract : Li-ion batteries have gained great popularity among researchers and practitioners as an environmentally friendly energy storage solution for more environmentally friendly electric vehicles (EVs). However, because of the increased demand for Li-ion battery-powered EVs, and some issues with battery design, legislation, collection and sorting, recycling, and material recovery, achieving sustainable mobility through the circularity of Li-ion batteries is a major challenge.
