Electrification of vehicles is an important part of the transition to a carbon dioxide-neutral and sustainable society. The biggest obstacle to a rapid transition is developing suitable energy storage systems for the transport sector. Battery and fuel cell systems are used today but both technologies have the potential to improve and become more competitive options.
Some characteristics that are valued are environmental friendliness from a life cycle perspective, high energy density, fast charging capability, long life, manufacturing price and safety.
Research for safe and optimal energy storage
Our research aims to design energy storage systems that make optimal use of batteries or fuel cells in a safe way. This includes;
- electrical construction of, for example, battery packs.
- dimensioning of electrical components in a powertrain to optimize energy losses and manufacturing costs.
- optimal management of battery usage to reduce energy losses and increase lifetime as well as estimate lifetime and monitor battery systems for safe robust operation.
Our research environment
The division of Vehicle Systems have a self-developed battery rig with an associated battery management system. There, control strategies can be tested and measurement data collected. Methodologically, physics-based and data-driven modelling, simulation, control and optimization are used.
