Formula Student class electric vehicle energy storage - study and design assumptions

Abstract

The goal of this article is to present the design assumptions of an energy storage for a Formula Student electric car equipped with one electric motor. The correct selection of the parameters of the energy storage is dictated by the regulations applicable to all cars competing in this class, especially the maximum battery power. The growing interest in electric cars is visible also in motorsport, where are created new competitions and classes specifically for BEV (Battery Electric Vehicle). The study presents a description of the requirements contained in the competition regulations regarding the energy storage in the Formula Student vehicle, an overview of the cells that can be used in the battery and the selection of the most optimal among several solutions. Based on specific requirements, the arrangement of cells inside the battery was designed, divided into smaller segments and their connection, placed in a safe housing in the form of container.
