ACCURE Predictive Battery Analytics Platform for BESS

ACCURE Battery Intelligence is a battery analytics company headquartered in Aachen, Germany, founded by Dr Kai-Philipp Kairies, Dr Johannes Palmer and Dr Georg Angenendt, who led a large grid-battery research group since 2008. It helps owners and operators of grid-scale storage prevent failures, cut costs and capture more value from their batteries.

The platform combines AI and physics-based models with performance engineers to process BMS and PCS data. Modules cover safety, performance and lifetime management, state-of-charge correction, warranty claims, insurance analytics, PCS analytics and task management. Services span procurement benchmarking, factory acceptance quality assurance, commissioning, augmentation planning and emergency response. The company reports more than 24 GWh of supported capacity.

• Safety Manager: early detection of battery risks and anomalies.
• SOC accuracy: corrected state-of-charge values for dispatch and trading.
• Lifetime and performance managers: degradation tracking and energy optimisation.
• Warranty and insurance: evidence for claims and improved insurance conditions.
• PCS analytics: monitoring of power conversion efficiency and faults.
• Lifecycle services: procurement benchmarks, FAT quality assurance, commissioning and augmentation planning.

Owners of new BESS projects in Vietnam could use independent factory and commissioning checks before accepting equipment. Banks financing storage could rely on analytics to assess availability and degradation risk. Insurers could use continuous safety monitoring when underwriting battery sites.

A Repsol case study reports a 32% increase in battery lifespan. Correcting state-of-charge errors protects trading revenue, which the company estimates can exceed USD 1 million per GWh per year for LFP systems. Independent analytics support warranty claims, insurance terms and financing, and early detection targets small recurring outages that cause most downtime.

As grid-scale storage portfolios grow, owners, lenders and insurers want independent, vendor-neutral data on safety, availability and degradation. ACCURE research across more than 50 projects found three in four sites over-report availability. Asian markets building large storage fleets, including Vietnam, will face the same need for bankable performance data.

Headquartered in Aachen, Germany, with ISO 27001:2022 certification. Recognised by Frost & Sullivan, Cleantech Group Global Cleantech 100 and World Economic Forum Technology Pioneers. Received investment from Copec WIND Ventures in July 2026. Customers and partners include Repsol, ENGIE, Econergy, AMP, Aviva and HDI Global.
