Sales expenses associated with charge-state analyses may amount to as much as 10% of total earnings.
In the quest for a more sustainable energy future, ACCURE Battery Intelligence is leading the charge with its innovative predictive analysis software for battery storage. The company's primary goal is to predict failures early, minimize risks, and optimize performance in battery systems, thereby playing a pivotal role in the energy transition.
Battery storage systems, particularly lithium iron phosphate (LFP) cells, face challenges such as not delivering expected performance, aging faster than planned, or developing safety-critical conditions. ACCURE's platform aims to address these issues and be a central tool to accompany and shape the transformation of the energy system, beyond just stationary storage.
One of the key challenges in LFP cells is balancing. Usually, balancing is only done in edge areas, but if a storage system is not regularly fully charged or discharged, larger differences between the cells can develop over time. ACCURE's platform can analyze sodium-ion cells more easily than LFP cells due to their steeper open-circuit voltage curve. However, with LFP cells, the platform employs a multi-stage safety monitoring system with over 20 indicators to identify potential risks in second-life batteries.
The amount of lost capacity that can be recovered depends strongly on the previous operation and condition of the system. Factors influencing capacity recovery in LFP cells include the charge/discharge rate, state of charge management, cell chemistry stability, and balancing of individual cells. Balancing plays a critical role by equalizing the state of charge (SOC) across cells in a battery pack, preventing capacity loss caused by cell voltage differences.
Specifically, fast charging or high C-rates negatively affect capacity retention. Maintaining the SOC within an optimal range (e.g., 20% to 90%) reduces stress and prolongs cell life. The intrinsic stability of LFP chemistry enables some reversible loss and regain of capacity due to reversible lithium intercalation/extraction within a certain voltage window.
In summary, capacity recovery in LFP cells depends on operating conditions that preserve cell chemistry and the effective balancing of the battery pack, which ensures all cells contribute equally and prevents capacity-limiting imbalances.
Reliable and forward-looking monitoring is essential for battery storage systems. ACCURE's platform is independent of whether it's a first-life or second-life system, making it versatile and adaptable to various applications. The company's long-term vision is to make all the world's batteries better: safer, more sustainable, and more cost-effective.
The EU Battery Regulation is a driver of innovation for ACCURE, promoting transparency, data availability, and sustainability. While some parts of the regulation are still vaguely formulated, it is generally moving in the right direction. ACCURE primarily uses physically-based models to ensure transparency in their algorithms, aligning with the principles of the EU Battery Regulation.
Dr. Georg Angenendt, the CTO and co-founder of ACCURE Battery Intelligence, leads the team in their mission to revolutionize battery storage. ACCURE is ISO-certified, underscoring their competence in securely handling sensitive battery data. Incorrect state-of-charge estimates in LFP cells can result in up to 20% errors, which can lead to up to 10% loss in revenue. Predictive battery analytics can reduce the estimation error to around 2%, significantly improving economic viability.
Battery storage plays a key role in the energy transition, particularly for stabilizing grids, balancing peak loads, and enabling flexible power supply. With ACCURE's predictive analysis software, the future of battery storage looks brighter and more sustainable than ever before.
- In the realm of energy transitions, ACCURE Battery Intelligence's predictive analysis software for battery storage, with its focus on minimizing risks and optimizing performance, is poised to play a vital role in the finance and technology sectors, as well as the energy industry, due to its potential impact on battery systems.
- To tackle challenges in both lithium iron phosphate (LFP) cells and sodium-ion cells, ACCURE's platform employs a multi-stage safety monitoring system, employing over 20 indicators for LFP cells to identify potential risks in second-life batteries, and easier analysis for sodium-ion cells due to their steeper open-circuit voltage curve.
- With the EU Battery Regulation driving innovation for companies like ACCURE, the company's long-term vision is to contribute to a more sustainable future, making all the world's batteries safer, more cost-effective, and aligned with the principles of the regulation, thereby impacting the business and finance sectors positively.
