John Cockerill, enablers of opportunitiesDriven since 1817 by the entrepreneurial spirit and thirst for innovation of its founder, the John Cockerill Group develops large-scale technological solutions to meet the needs of its time: facilitating access to low carbon energies, enabling sustainable industrial production, preserving natural resources, contributing to greener mobility, enhancing security and installing essential infrastructures.Its offer to businesses, governments and communities consists of services and associated equipment for the sectors of energy, defence, industry, the environment, transports, and infrastructures. With more than 8,000 employees, John Cockerill achieved a turnover of € 1.417 billion in 2024 in 28 countries, on 5 continents.John Cockerill has been providing its expertise to the defense industry for 200 years. Today, John Cockerill Defense offers Cockerill® modular gun turrets from 25 to 120 mm caliber, Arquus® high-mobility vehicles, technical and tactical training on these systems, and Agueris simulators.Your Mission:The goal of this thesis is to develop a BMS (Battery Management System) for ruggedized environment. The study should be made for 24V and for 48V applications. The typical RMS current is 100A.1. Exploration and need definitionYou will investigate/analyse BMS characteristics to define which one are needed. After definition of the required characteristics and specifications, a BMS IC should be selected.Figure 1: Typical cylindrical (18650 or 21700) cell assembly.2. ArchitectureAn architecture should be defined so that the integration into new products is possible with ease. The architecture should consider the fact that both the 24V and the 48V configuration are possible.3. Test of the BMS ICYou should be able to assess the selected IC in real conditions using demo boards. After testing, the IC selection should be either validated or rejected.4. Create one prototype.When a BMS IC is validated and pre-tested, a PCB should be made to fulfil the initial requirements in terms of footprint, electric characteristics, etc.Subject discussed:
