Battery manufacturer Clarios has reached an important milestone: The company has produced its one millionth 12-volt lithium-ion battery. 12-volt lithium-ion batteries are crucial not only for electric vehicles but generally for vehicles with high electrification.

"We develop advanced battery solutions necessary for the future of transportation," is the motto Clarios proudly upholds, nothing more and certainly nothing less. Now, the company has celebrated an important milestone with its one millionth 12-volt lithium-ion battery—thanks in part to its global network.

Clarios manufactures lithium-titanate oxide cells in the USA and assembles facilities in Europe near its customers. With the production of six million prismatic 10-Ah LTO power cells and one million 12-V lithium-ion batteries, it has transformed from a pure manufacturer of lead-acid batteries to a chemistry-independent provider of energy storage. The manufacturer produces all LTO cells in its own plant in Meadowbrook, USA. The production line for lithium-ion low-voltage batteries, on the other hand, was commissioned in Hanover (Germany) in 2020. Since then, the company has further developed its technologies and expanded production capacities.

Made in Germany

The lithium-ion assembly site in Hannover plays a central role in the company's global production strategy. Clarios has its headquarters for Europe, the Middle East, and Africa, as well as an important plant in Hannover-Stöcken. Around 1,300 employees are based in the capital of Lower Saxony.

The site belonged to the Varta Group for decades. In 2002, Johnson Controls acquired Varta and invested in the Hannover plant. In 2019, Johnson Controls sold the Power Solutions division to Brookfield Business Partners, leading to the creation of Clarios.

In Hannover, modern energy storage systems for worldwide use are now being developed. The production line for manufacturing low-voltage battery systems serves as a blueprint for other locations. The manufacturer has particularly developed new expertise in engineering and software development. The acquisition of Paragon Power business in 2023 also enabled Clarios to bring in additional expertise and staff into the existing team.

Identify and develop new technologies

Currently, Clarios produces 12-volt high-performance lithium-ion low-voltage batteries for vehicles and is working on new technologies such as sodium-ion batteries, supercapacitor solutions, and dual-voltage systems. With the millionth lithium-ion low-voltage battery, the company sees itself well-equipped for future challenges in the mobility sector. The company plans further investments in research and development as well as the expansion of its product portfolio.

Battery intelligence in focus

One topic the manufacturer is also focusing on is real-time battery monitoring. In this regard, the company has expanded into software-based vehicle services with Clarios Connected Services. Clarios Connected Services combines artificial intelligence (AI), machine learning, and cloud computing. The system uses proprietary algorithms to turn battery data into actionable insights, with the aim of helping fleets and drivers reduce operating costs and carbon footprints.

Clarios' data platform relies on the company's experience in battery development and manufacturing for various battery chemistries with proprietary software and advanced trend analysis. It is secure and adaptable for all low-voltage battery chemistries and vehicle applications. Clarios will offer its digital services in EMEA under the VARTA Automotive brand. (se)
