| Description: |
Background Battery technology is increasingly becoming part of many industrial segments due to the increasing demands of electrification. Several emerging sub-technologies are emerging to optimize and improve battery performance, longevity, pricing, etc. A heterogenous battery is a battery containing different underlying cells as the basic components. Using a heterogenous set-up can potentially enable a configurable and flexible operation, which could improve the adaptability of a battery system by utilizing different cells at different operational conditions. In this way, the right battery cell type can be used for its respective strong suit during dynamic operation (such as electrical vehicles), instead of using a “one size fits all” battery as is typically done today. However, the use of a heterogenous battery system introduces complexity in the actual HW and SW implementation, which this thesis aims to improve in regard to current implementations. Particularly, a heterogeneous system needs to be able to discharge several cells with different electrical characteristics at the same output line, and manage switching between sources at high-frequencies for a stable output/input during operation. This thesis will be done in collaboration with Nordic Engineering Partner (NEP). Tasks The student(s) are to work upon previous work and improve the heterogenous battery system regarding one ore more of the following: -Optimize battery operation at run-time -Implement policies for operation, for example to maximize life-length -Improve electrical design to minimize losses -Efficient sensor system to gather real-time data in difficult to measure environments |
