The activities carried out by SEGULA Technologies in relation to the development of the battery pack focus on several key areas

Study of the Battery Management System (BMS), the integrated control unit within the battery pack, is essential for monitoring the battery’s health, determining its state of charge, managing the charging process, and optimising battery usage to ensure longevity. The BMS retains data on the battery’s behaviour to better manage its performance.

Mechanical simulations, such as crash tests and “thermal venting” analysis, are conducted to track the expulsion of hot gases in the event of a thermal runaway, aiming to prevent these incidents. Additionally, the heating and cooling systems are studied to manage fast charging and prevent cell ageing.

Competitive analysis of battery technologies is carried out to stay ahead in innovation.

Reflection and analysis of potential safety concerns related to the battery’s functionality are considered throughout the product development process.

Supplier management for battery pack components and procurement, as well as maintaining technical relations with these suppliers, is a key focus.

Battery ageing analysis is conducted during normal usage, incorporating feedback and managing mechanical and electrical validation processes.

Compliance with various regulatory standards is critical. SEGULA Technologies performs testing on prototypes in collaboration with partner organisations to obtain approvals and assess how the batteries can be integrated into the vehicle.

Global battery simulations are carried out to ensure proper performance during a WLTP (Worldwide Harmonised Light Vehicles Test Procedure) cycle, which measures the range of electric vehicles.

Management of real crash tests and all potential incidents is also a crucial part of the process.

“For various car manufacturers, we are already working on improving the battery pack, for which we are able to internally deploy all the skills related to this activity. In this context, we have centres of expertise in several countries — France, Morocco, Tunisia, Romania, Spain — each with their own specialities, while simplifying communication through a single point of contact,”
