ENERGY STORAGE
Battery and battery management in electric vehicles
Project manager: Miguel Dhaens
Crucial for the development and acceptance of electric vehicles is the availability of sustainable, reliable and cost-efficient energy storage, for instance in batteries. In this project, we study the latest generation of lithium-ion batteries for electric and hybrid vehicles, paying considerable attention to the battery management system as well.

Goals
In this project, we develop a modular battery pack that can be used both in hybrid and fully electric cars and buses. The battery pack consists of lithium cells connected in parallel or in series and linked to an intelligent battery management system.
Methodology
First, expertise on lithium batteries is built, which is then used to develop an intelligent management system that can control the batteries safely and efficiently.
Phases
- Defining the system requirements and market study
- Testing cells and developing a simulation model
- Developing a modular architecture for combining battery cells with a battery management system
- Building a battery pack
- Testing the battery pack and developing a simulation model for the entire system
Results
- Market study report based on, a/o, contact with more than 150 battery manufacturers
- Knowledge of and experience in selection criteria for lithium-ion batteries for traction purposes
- Development of a test plan for the fast characterisation and modelling of batteries
- Recommendations to the standardisation committees regarding battery tests
- Designing of a modular battery pack architecture
- Knowledge of and experience in the protection and control of lithium-ion batteries and development of an intelligent battery management system
- Development of an innovative battery model for the accurate prediction and control of battery packs
