Engineering Technical Specifications for Formula Student Electric Powertrain System (FSAE / FSTaiwan)

This document serves as a comprehensive engineering roadmap and strategic framework for developing a world-class Battery Management System (BMS) for Formula Student electric racing. It outlines a shift from defensive regulatory compliance to an offensive design philosophy, where the BMS acts as the vehicle's "neural center" to maximize energy extraction and performance at the physical limits of the hardware. The technical specifications advocate for a distributed master-slave architecture using isoSPI communication to achieve extreme lightweighting and high data fidelity. Beyond hardware, the text emphasizes advanced software algorithms, such as Extended Kalman Filtering for precise state estimation and dynamic power limiting, to ensure the car remains competitive and reliable during endurance events. Ultimately, the source provides a rigorous blueprint for building custom, data-driven systems that surpass off-the-shelf solutions in both safety and racing efficiency.
