HSBC Asset Management among investors in battery data analytics provider ACCURE


ACCURE has raised €7.2 million (US$7.8 million) funding for its analytics software solutions that can enable a “proactive approach to safety” in the battery storage industry.  

The Germany-headquartered battery analytics specialist said today that it has secured the investment from funding round leaders Blue Bear Capital, a high-growth tech investment group, and HSBC Asset Management, a subsidiary of the global HSBC Holdings banking and financial services company.

ACCURE gathers a combination of lab-level and field operation data to forecast and determine the health of batteries, yielding important insights on everything from battery lifetimes to optimal operating schedules. The company’s tech leverages a predictive analytics platform based on AI, field data and modelling.

As readers of will likely know, ACCURE is one of a number of cloud-based battery analytics providers, with CEO Dr Kai-Philip Kairies an occasional commentator on related topics to the site, as well as author of a handful of contributed articles for and our quarterly journal PV Tech Power.

While the largest target market segment for ACCURE and its rivals will likely be the electric vehicle (EV) and wider e-mobility sectors, the solution has an important role to play in the stationary energy storage system (ESS) industry too, CEO Kairies told

In a 2022 article for PV Tech Power (Vol.32), Kairies wrote about the way cloud-based analytics can be used to predict critical faults in battery energy storage system (BESS) assets and provide insights to correct them before any damage occurs.

“We see the BESS industry adopting a data-centric approach to safety that emphasises anomaly identification before an event occurs. Our customers understand battery data’s important role in maintaining a reliable and safe system,” Kai-Philip Kairies told yesterday.

“With our predictive analytics platform, we can detect potential issues and threats several weeks before escalation into a thermal runaway event.”

The company claimed its solution has prevented more than 50 battery incidents, as well as improving performance and output of utility-scale energy storage systems worldwide. Kairies claimed more than 2.6GWh of battery assets have been onboarded to the platform to date.

According to Kairies, while the capabilities of the platform are “extremely valuable” to BESS asset owners, insurance companies have also taken note, the CEO claimed, with some insurers “offering reduced obligations, deductibles, or even lower premiums” for projects utilising analytics.

“It’s this sort of proactive approach to safety that is going to propel the industry forward,” Kairies said.

The news builds on a US$8 million fundraise for ACCURE in 2022. It also comes shortly after US battery analytics provider Peaxy raised US$12 million in July for its platform Peaxy Lifecycle Intelligence (PLI). Fellow Germany-based rival TWAICE raised US$26 million in 2021.
