Mercedes‑Benz Energy (founded 2016) is a Mercedes‑Benz AG subsidiary in Großröhrsdorf, Germany that develops modular stationary energy storage using second‑life EV battery modules and advanced battery chemistries for grid, commercial and residential uses.
Mercedes-Benz Energy GmbH, founded in 2016 and headquartered in Großröhrsdorf, Germany, is a wholly owned subsidiary of Mercedes‑Benz AG. The company develops and manufactures stationary battery energy storage systems that repurpose automotive lithium‑ion modules and integrate emerging battery chemistries. Its mission is to extend battery life through second‑life applications, reduce environmental impact, and support renewable energy integration. Operations include modular, scalable BESS products, residential and commercial solutions, and collaboration on advanced battery prototypes and recycling to support a circular battery economy.
Mercedes‑Benz Energy’s core technology centers on secondary use of automotive lithium‑ion modules combined with modular power electronics and system controls in its MBESS line. Second‑life modules are tested, qualified and reconfigured into containerized or site‑built BESS units offering 600 kW and 1,200 kW power modules and per‑unit capacities from 1.56 MWh to 6.24 MWh, scalable beyond 100 MWh. This approach delays recycling to lower embedded carbon and lifecycle cost while applying automotive safety standards. The company also participates in lithium‑metal solid‑state prototype testing and holds multi‑year cell supply agreements to secure consistent cell sources.
MBESS is a modular, scalable energy storage product line using refurbished Mercedes‑grade battery modules or new cells for stationary use. Available as 13‑foot containerized systems or in‑house installations, power blocks are 600 kW and 1,200 kW with storage from 1.56 to 6.24 MWh. Applications include peak shaving, PV self‑consumption optimization, backup power, frequency control and industrial energy management for commercial, utility and residential customers.
In 2025 Mercedes‑Benz Energy supported road testing of EQS prototypes equipped with Factorial Energy’s lithium‑metal solid‑state cells in collaboration with Mercedes‑AMG High Performance Powertrains. The pilot demonstrated roughly 25% range improvement (approaching 1,000 km in test configurations) and produced real‑world data on integration, safety and thermal management to inform next‑generation vehicle and stationary pack development.
Mercedes‑Benz Energy is a wholly owned subsidiary of Mercedes‑Benz AG and operates without publicly disclosed external funding rounds. Financial and strategic backing is provided through the parent company; there are no independent investors or venture funding reported.
