Accuracy issues in state-of-charge estimations can lead to financial losses of up to 10% in sales.
In the quest to transition to renewable energy sources, battery storage systems play a pivotal role. ACCURE Battery Intelligence, a pioneering company, is at the forefront of this revolution, with a long-term vision to make all batteries safer, more sustainable, and more economical.
Dr. Georg Angenendt, the CTO and co-founder of ACCURE, leads the charge. The company's ISO certification underscores their expertise in handling sensitive battery data securely. ACCURE's platform relies on multi-stage safety monitoring with more than 20 indicators, ensuring reliable and predictive monitoring, a crucial aspect for battery storage systems.
ACCURE provides a comprehensible safety score from green to red for customers, making it easier to understand the safety status of their batteries. The company's focus is primarily on lithium batteries, including LFP, NMC, and LTO.
Sodium-ion cells, known for their steeper open-circuit voltage curve, are easier to analyze than LFP cells. ACCURE has had good experience with initial sodium-ion projects and continues to explore their potential.
Battery storage systems often fail to deliver the expected output, age faster than planned, or develop safety-critical conditions. Incorrect state of charge estimates can occur due to the flat voltage curve of LFP cells in the medium charge range and measurement inaccuracies in coulomb counting. ACCURE addresses these challenges with their predictive analysis software for battery storage facilities.
The EU Battery Regulation is a driver of innovation for ACCURE, calling for more transparency, data availability, and sustainability. ACCURE ensures that their algorithms remain comprehensible for operators through traceability and explainable indicators.
Balancing, or bringing the individual cells in a serial battery network to the same state of charge, is crucial for optimizing battery performance. Incorrect balancing can lead to reduced efficiency and capacity loss. ACCURE's predictive analytics can help reduce estimation errors, improving cost-effectiveness. Up to ten percent of lost capacity in battery systems can be recovered through targeted balancing.
Predictive battery analytics plays a crucial role by monitoring factors such as charge/discharge rates, capacity fade patterns, and temperature profiles. By using data-driven models, ACCURE's analytics can predict remaining battery life and optimal operation conditions, guiding adjustments in current rates and thermal controls to enable reversible capacity recovery and prevent irreversible degradation.
The interplay between cycling conditions, material integrity, and thermal environment governs capacity recovery in LFP batteries. ACCURE's predictive analytics facilitates informed management to enhance this recovery and overall battery performance.
ACCURE's goal is to predict failures at an early stage, minimize risks, and optimize performance. The company also works with start-ups like Voltfang that use second-life batteries. ACCURE's platform is independent of whether it's first-life or second-life systems, making it a versatile solution for various battery applications.
