TESVOLT AG is a German manufacturer specializing in energy storage systems for commercial and industrial applications. Founded in 2014 by Daniel Hannemann and Simon Schandert, the company has established itself as a leading provider of sustainable energy solutions. Operating from its base in Lutherstadt Wittenberg, TESVOLT develops and produces advanced battery storage systems that support businesses in their transition to renewable energy sources. The company’s solutions serve various sectors, including manufacturing, agriculture, and commercial enterprises, offering storage capacities from 10 kWh to 30 MWh. With over 5,000 successful installations worldwide, TESVOLT demonstrates its expertise in creating efficient, reliable energy storage solutions.
Battery Technology
TESVOLT’s technology centers on high-performance prismatic lithium-ion cells manufactured by Samsung SDI, utilizing nickel-manganese-cobalt-oxide (NMC) chemistry. These cells provide exceptional energy density and stability, with a recycling rate exceeding 90%. The company’s engineering excellence is evident in its proprietary Active Battery Optimizer (ABO) and DynamiX Battery Optimizer (DBO) systems, which enhance cell performance and longevity.
The storage systems feature modular designs that allow flexible configuration and expansion capabilities. TESVOLT’s battery management system monitors and optimizes each cell individually, ensuring maximum efficiency and extended lifespan. The technology supports integration with multiple renewable energy sources, including solar, wind, and hydroelectric power, making it versatile for both grid-connected and independent operations. All systems are manufactured in Europe’s first carbon-neutral gigafactory, demonstrating TESVOLT’s commitment to sustainable production methods.
Recent Projects
In 2024, TESVOLT began construction of a new gigafactory at its headquarters, representing a €30 million investment. The facility, scheduled to begin operations in 2025, will span 6,000 square meters and increase production capacity to 80,000 storage systems annually. The company also launched TESVOLT Energy, a subsidiary focused on profitable energy trading using commercial battery storage systems. This expansion includes developing proprietary software for optimal battery storage management and establishing partnerships with leading energy traders in Germany.
Investors
TESVOLT’s growth is supported by several significant investors, including the Liechtenstein Group, owned by the Princely Family of Liechtenstein, which led a €40 million funding round in 2021. Additional investors include the IBG-Fonds of Saxony-Anhalt, E.R. Capital Holding, and a prominent family office with automotive industry expertise. The majority of shares remain with co-founders Daniel Hannemann and Simon Schandert, ensuring continued strategic control.
