Abstract
This thesis tackles a common challenge in Formula Student teams: developing a reliable accumulator. Drawing from previous VUB Racing experience, the objective is to create a foundational accumulator design to serve as a blueprint for subsequent years.Within this thesis, one phase of the multiyear project is undertaken: the design,
manufacturing and testing of an accumulator segment. The segment is designed for a new accumulator that is reasonably dimensioned for VUB Racing’s existing powertrain.
Considerable effort was invested in manufacturing a Formula Student rule-compliant accumulator segment. Utilizing 3D-printing for rapid prototyping, a design-formanufacturing philosophy was implemented to optimize for the competition demands.
The finished segment underwent continuous discharge testing in a battery lab, where electrical and thermal characteristics were monitored to evaluate design decisions. Given the absence of active cooling, the hypothesis was that it might not withstand the tests.
The segment’s testing demonstrated that its design is sufficient for short race lap durations, confirming its potential for integration within an electric race car. This finalized segment lays the essential groundwork for future researchers, enabling them to focus on its integration within the accumulator.
VUB Racing’s electric powertrain has a promising road ahead. While the electrical puzzle of the accumulator has been solved, challenges remain in finalization of the complete accumulator and its vehicle integration.
