Title Master Thesis Project: Dynamic energy modelling of battery climate system in a whole cooling system perspective

Thermal management of batteries has become an important part of cooling control system development, since the number of hybrid and electrical vehicles are increasing. Traditionally thermal management and vehicle energy consumption have been analysed and optimized separately. However, the two topics are closely interconnected, and it is important to analyse them at the same time, to avoid sub optimization.

The objective is to develop a functional module of one or more types of battery thermal management systems in MATLAB Simulink. The module shall be integrated in ÅF’s Energy Model, which is a Simulink model for analysis of vehicle energy consumption and performance. The module shall analyse the Battery Thermal Management System (BTMS) together with the contribution of the vehicle’s total thermal systems, to increase the accuracy in sizing of the system, its components and predict the limitations of the system, and impact on vehicle energy consumption and driving range. It is desired to use a previous master thesis as a base and develop it further.

Through literature studies, interviews with subject matter experts, and theoretical analysis, determine which physical properties that need to be modelled and to which level of detail. Similarly determine which vehicle controls parameters and driving load cases that should be part of the scope. Validate the model through comparison with real life tests.


  • A functional Simulink module of the BTMS integrated in Energy Model that is simple to adjust to different conditions as driving cycle and components data.
  • Dimensioning of an example system, preferably with data from a real case, that clearly states the bottleneck of a defined driving condition
  • Analysis and optimization suggestions of the controls strategy of the target vehicle
  • Report and presentation
