Anna Copado Silva from Futavis GmbH presents on the evolution of battery diagnostics for VW batteries, highlighting the importance of accurate and diverse data collection to enhance diagnostic precision. At Futavis, they develop electronics and battery management systems (BMS), necessitating high-resolution measurements like current, voltage, temperature, impedance, and resistance at every cell level. However, achieving optimal diagnostics often conflicts with cost-effectiveness and system reliability. Silva discusses common industry practices such as parallel cell configuration to reduce complexity; instead of individual sensors for each cell, grouped cells share measurement points. For instance, fewer temperature sensors can be used across multiple cells rather than one per cell. She emphasizes addressing challenges in heating/cooling solutions by using PTC heating modules as a low-cost alternative while maintaining functional safety through rigorous testing. Furthermore, reducing sensor numbers is crucial but must not compromise data integrity or functional safety—achieved via integrated circuits with diagnostic functionalities. Ultimately, finding the best BMS solution depends on specific applications' needs balancing performance against costs while ensuring safety standards are met.
