Tiivistelmä
The purpose of this thesis was to document information on designing and manufacturing process of a high voltage battery for a Formula Student competition vehicle. The thesis discusses component selection, design of the battery container, material selections and electrical design. The manufacturing methods, for example composite work, 3D-printing and machining are described as well as possible alternative possible design solutions.
Most of the safety aspects of the design come from the Formula Student Rules. This thesis explains the principles behind the rules which give a good background for safe battery design. Some examples of electrical properties of the materials are provided.
Designing an electric vehicle battery is largely component selection, and the most important part is battery cell selection. Several alternative battery cells are compared to each other in order to find the most suitable battery cell, and the reasons for selecting certain battery cell are documented. The thesis explains with the selection of several parts, which could help in the selection of other corresponding parts needed in similar projects.
The thesis includes examples of a high voltage battery that was used by Metropolia Motorsport for two consecutive competition seasons 2018 and 2019. The data logged by the battery management system and the vehicle data logger was used to evaluate the success of the design and provide more information of the battery in use.
