Electronic System Design of a Formula Student Electric Car

Abstract

This paper addresses the design of the Data Acquisition System, Battery Management System and the different safety circuits present in a Formula Student Electric Vehicle. The car was designed around the rules and regulations of the Formula Bharat 2019 Competition while keeping efficiency and cost in mind. The data acquisition system was designed to utilize the sensor network in the car, in real-time, based on a master-slave topology. A robust battery management system that monitors current, voltage, temperature and SoC of the battery pack and maintains a safe functionality was required and three safety circuit systems for fault analysis and alarming in case of any electrical malfunctions. These systems are brought together with the help of the wiring harness to keep it as compact and light-weight as possible.
