Megawatt Scale Li-Ion Batteries Mounted in Opposition to Save Power During Test
After an accurate job from Engineering, Industrial , Prototype and Testing teams, and multiple meetings dedicated to risk analysis and safety consideration the dream came true and a 3MW container has been cycled under power equivalent to 2,3MW charge / discharge. The battery voltage was close to 800V, thermal power inside the container equivalent to 2.3MW electrical cycles, while the test bench was delivering only 50kW power representative of joule losses within the cells.
A Battery Cell Emulator for Hardware in the Loop Tests of Reconfigurable Lithium-Ion and Post-Lithium Batteries
A modular battery emulator for reconfigurable battery topologies is presented. The battery emulator is based on linear controllable power electronic boards, which are used to emulated cells with lithium-ion or post-lithium cell chemistry. The individual emulation boards can be connected in series as well as in parallel. Each cell can source and sink currents up to 6 A. The final design will increase this to 18 A.
Combined Sensor Minimal Cell-Monitoring and Active Inductive or Capacitive Cell-Balancing
A new balancing system that allows to transfer energy between any two cells with high efficiency and least amount of battery load, while this system likewise allows monitoring of all cells individually without additional wiring is presented. With two realisation options it allows a voltage based balancing in the capacitive mode or balancing based on any (fictive) characteristic curve (e.g. SoC) in the inductive mode. In addition, module balancing can easily be applied to the system.
Karlsruher Institut für Technologie (KIT), Eggenstein-Leopoldshafen, Deutschland
Simon Bischof received his Master's Degree in Electrical Engineering from the Karlsruhe Institute of Technology (KIT) in 2016. He is now working as a PhD student in the Group of Huge Battery Systems at KIT and is a member of the DFG research training group "Energy status Data". His main focus is on energy informatics and battery systems for industrial applications.
SAFT, Bordeaux, Frankreich
Power conversion expert at SAFT Engineering department, Bordeaux, France. He holds an Engineer degree in Electrical Engineering (ENSEEIHT) and Power electronics Master degree from Toulouse university (both in 1990). He has 25 years of experience in power electronics and Electrical systems engineering. After 10 years of design of power converters (SMPS, chargers and Induction heating) he worked as technical consultant in several big companies mainly on aerospace system engineering and integration programs. Since 2010 he has joined SAFT as Power electronics expert to work on power conversion systems for Energy storage programs and to support Battery systems engineers and program managers for power solutions design.
Ruhr University Bochum, Bochum, Deutschland
Prof. Dr.-Ing. Constantinos Sourkounis achieved his engineer?s degree and his PhD degree at the Technical University (TU) of Clausthal, Germany in 1989 and 1994. After he received his PhD at the Institute of Electrical Power Engineering at the TU Clausthal, he occupied the position of the chief engineer. In 2003 Prof. Dr.-Ing. Sourkounis achieved his habilitation. Since then he is working as professor at the Ruhr-University Bochum, leading the Institute for Power Systems Technology and Power Mechatronics. His main research areas are mechatronic drive systems, renewable energy sources, decentralised energy systems supplied by renewable energy sources, and energy supply systems for transportation systems.
