This report discusses the design of an accumulator pack and the tractive system for an FSAE electric race car. The accumulator is a custom-built lithium-ion battery pack that includes everything required for safe operation and to supply power to the motor controllers. FSAE constraints for the competition are met by conducting a thorough
The design of the battery modules and the battery pack must take into account factors related to impact strength, vibration resistance, and heat resistance at each level, i.e., both at the module level and at the battery level. The main source of danger when using Li-ion batteries is thermal runaway. The causes of the onset of this phenomenon may be the

At the heart of every EV lies a remarkable technological innovation – the battery module. These compact, powerful energy storage units are revolutionizing the automotive industry and have become the backbone of sustainable transportation. Central to the development of high-performance EVs is the design and engineering of the battery module.
The design solutions are assessed from an assembly, disassembly and modularity point of view to establish what solutions are of interest. Based on the evaluation, an “ideal” battery is developed with focus on the hardware, hence the housing, attachment of modules and wires, thermal system and battery management box.
Material selection and assembly method as well as component design are very important to determine the cost-effectiveness of battery modules and battery packs. Therefore, this work presents Decision Matrix, which can aid in the decision-making process of component materials and assembly methods for a battery module design and a battery pack design.
A battery has several ways to implement modularisation and among these are design of the housing and module as well as concerning the management of its environment.
The battery modules on the other hand, are already modularised in the way that the same type is used throughout the pack. Next, the module frame consists of one frame with equally distributed gaps for the battery module connections. Two respectively three of these frames, modules, can be applied in the heavier trucks.
The BMS and power relays can be found inside the pack whereas the DC-DC converter, HV controller and other HV units are mounted in other parts of the vehicle. Furthermore, the pack consist of ten modules, divided in two rows and two levels with the lower modules containing 30 cells and the upper modules 24.
