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. Predicting Lithium-Ion Battery State of Health using Linear Regression

   University essay from Uppsala universitet/Statistiska institutionen

   Author : Niklas Sundberg; [2024]
   Keywords : Lithium-Ion; Multiple Linear Regression; State of Health; Voltage Deviation;

   Abstract : Knowledge of battery health is very important. It provides insight into the capacity of a given system and allows the operators to plan ahead more efficiently. But measuring state of health (SoH) of a battery is difficult, and takes time. More importantly, the battery needs to be taken out of operation to be analysed correctly. READ MORE

4. 3. Hardware Subsystem Proposal of an Off-Vehicle Battery Analyzer from a Charging/Discharging Perspective

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Rinor Gashi; Tim Johansson; [2023]
   Keywords : battery electric vehicles; power conversion module; off-vehicle battery packs;

   Abstract : Electric Vehicles (EVs) are seen as one of the solutions to some of the world’s global current problems, such as global warming and air pollution, due to non-existent operational emissions and increased efficiency. There are multiple types of EVs, one of them being Battery Electric Vehicles (BEVs) which in most cases utilizes a Li-Ion battery pack as energy storage. READ MORE

5. 4. Minimising Battery Degradation And Energy Cost For Different User Scenarios In V2G Applications : An Integrated Optimisation Model for BEVs

   University essay from Uppsala universitet/Elektricitetslära

   Author : Jacob Bengtsson; Benjamin Moberg Safaee; [2023]
   Keywords : Vehicle-to-Grid; V2G; Battery Electric Vehicle; BEV; State-of-Charge; SoC; State-of-Health; SoH; charging; discharging; degradation; energy cost; optimisation; optimization; Pyomo; Gurobi;

   Abstract : The functionality to both charge and discharge energy from and to the power grid to a Battery Electric Vehicle (BEV) is referred to as Vehicle-to-Grid (V2G). This allows the customer to buy energy when the spot price is low and sell energy when the price is high to make a profit, called energy arbitrage. READ MORE

6. 5. Pulse Charging of Li-ion Batteries for Enhanced Life Performance

   University essay from KTH/Kemiteknik

   Author : Josefin Strandberg; [2023]
   Keywords : Li-ion battery; Pulse charging; Cyclic aging; Capacity fade; Internal resistance; Battery impedance; Litiumjonbatteri; Pulsad laddning; Cyklisk åldring; Kapacitetsminskning; Inre resistans; Batteriimpedans;

   Abstract : Det överhängande behovet av att minska utsläppen av växthusgaser för att uppfylla Parisavtalet har väckt ett ökat intresse för elektrifiering som en strategi för att mildra klimatförändringarna. Litiumjonbatterier spelar en central roll vid elektrifiering och har framträtt som det primära alternativet för batteridrivna elfordon. READ MORE
