Summary

In this episode of the Geladen podcast, hosts Patrick Rosen and Daniel Messling discuss battery aging and diagnostics with two guests: Professor Wolfgang Bessler from Offenburg University and Simon Schwab, founder of the startup AccuVice. They explain the concepts of State of Charge (SoC) and State of Health (SoH), which are crucial for battery users. The conversation highlights that traditional battery management systems (BMS) use current-controlled models, integrating current over time to estimate SoC and SoH. However, this approach has limitations, such as sensitivity to current measurement errors and the need for initial reference points. AccuVice introduces a novel voltage-controlled model that uses voltage as the input, simplifying calculations and improving accuracy. This method is self-calibrating, requires less computational power, and can handle various cell chemistries, including LFP, which has a flat voltage curve and hysteresis. The startup offers cloud-based diagnostics, providing real-time transparency and planning for battery operators. The episode also includes a sponsored segment for Wechselpilot and mentions Smart Green, a network for green tech startups.
