1. State of Health measuring of NiMH batteries using simple electronic components.
University essay from Linköpings universitet/FordonssystemAbstract : 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.

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 fysikAbstract : 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.

3. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system
University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknikAbstract : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance. READ MORE

4. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. READ MORE

5. Parallel Operation of Grid-Forming Power Inverters
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE
