1. 1. Analogue Circuit for Detection of Ageing Phenomena in Electric Drives

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Yudong Lin; [2023]
   Keywords : Electric Drives; Ageing Process; Pulse-Width Modulation; Ringing Current; Peak Holder; Analogue Circuits; Elektriska drivsystem; Åldringsprocess; Pulsbreddsmodulering; Ringningar i strömmen; Toppvärdesdetektor; Analog krets;

   Abstract : This master thesis presents an analogue peak holder circuit design aimed at facilitating the non-invasive inspection of the ageing process in electric drives. The ageing process of electric drives is a crucial aspect that demands accurate monitoring to ensure their long-term performance and reliability. READ MORE

3. 2. Open-Circuit-Voltage hysteresis measurement and modelling of LiFePO4 Batteries : Master Thesis Report - 2023

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Guillaume Larrat; [2023]
   Keywords : Open-Circuit-Voltage OCV Hysteresis - Voltage relaxation - Galvanostatic Intermittent Titration Technique GITT - Hysteresis modelling; Öppenkretsspännings OCV hysteres - Spänningsrelaxation - Galvanostatisk intermittent titreringsteknik GITT - Hysteresmodellering;

   Abstract : In a context of an expected increasing use of Lithium-ion batteries in the transportation sector, Volvo AB is developing its own solutions for large electric vehicles. It is then beneficial to reduce the costs, the energy demand and the raw materials demand by improving the battery systems’ performances. READ MORE

4. 3. Suppression of Li-ion Battery Fires

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Linfan Cai; [2023]
   Keywords : Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

   Abstract : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

5. 4. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Fan Yang; [2023]
   Keywords : Converter Design; Dual Active Bridge; Single Phase Shift Modulation; Extended Phase Shift Modulation; Efficiency Estimation; Konverterdesign; Dual Active Bridge; Single Fas Shift Modulation; Extended Phase Shift Modulation; Effektivitetsuppskattning;

   Abstract : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. READ MORE

6. 5. A General Purpose Analog Circuit to Accumulate Data From Resistive Sensors

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Karl Höjlund; Alan Alhallak; [2022]
   Keywords : Data acquisition; Wheatstone bridge; Analog conditioning; Digital potentiometer;

   Abstract : Minimizing the need to physically adjust hardware platforms used for sensor measurements during the construction phase of an electric vehicle can be beneficial. Since different sensors have different measuring ranges a hardware platform used for a specific sensor might not work for another one, without physically tampering with it. READ MORE
