Experts Discuss Challenges and Solutions in Battery Quality at Industry Session

The session on battery quality, moderated by Kai-Philipp Kairies, CEO and co-founder of ACCURE Battery Intelligence GmbH, focuses on the challenges faced in maintaining high-quality standards in large-scale battery installations. The discussion highlights that over 50% of batteries produced as of May 2025 come from production lines less than two years old, indicating potential quality issues due to rapid scaling. Furthermore, more than half of construction crews working with these systems may lack prior experience with batteries. These factors contribute to an industry grappling with consistent quality problems amidst exponential growth in cell production and workforce expansion. Kai-Philipp shares insights from ACCURE's work analyzing around 15 gigawatt hours worth of assets using data analytics to predict safety incidents and performance reductions. Case studies reveal common issues such as mismatched cells leading to imbalances and accelerated aging or faulty BMS sensors causing incorrect operational decisions. To address these concerns effectively, four experts are introduced for further discussions on mastering critical aspects related to battery quality assurance—beginning with Andres' presentation focused on unlocking success through expertise gained over a decade-long career in the field.

Talk of session: Quality Indicators in Large Scale Storage Systems: What to Look For

As the share of fluctuating electricity producers (PV and wind power) increases, energy storage systems will have to take on more functions in the grid. Batteries play a key role here; from commercial and industrial storage systems to utility-scale storage for multiple uses, the requirements are rising. Key quality indicators are not only safety (including functional safety) but also reliability as well as performance, defined by efficiency and effectiveness, over an ideally long service life. Site-specific requirements, such as noise generation, are also important considerations. This session will examine these aspects from different perspectives, offering recommendations beyond existing standards based on operational experience.
