Gotion starts mass production of liquid-cooled 5 MWh battery storage system at plant in Germany

Gotion High‑tech has started localised production of its 5 MWh liquid‑cooled battery energy storage system (BESS) at its Göttingen, Germany facility, following TÜV SÜD certification under the EU Battery Regulation (EU) 2023/1542.

The system uses Gotion’s own battery cells rated for 12,000 cycles, and offers a modular design that reduces footprint by roughly 35 per cent. It features liquid cooling, multi‑layer insulation and fire‑protection systems, and multi‑protocol communication capabilities. Gotion claims roughly 30 per cent higher energy efficiency compared to traditional air‑cooled systems. The system also carries China’s GB certification and CSA/UL credentials.

The Göttingen plant, acquired from Bosch in 2021, began producing battery packs in September 2023, with a range of products including both automotive and stationary energy storage products. The plan also serves as a logistics, R&D and after‑sales hub for Gotion’s European operations. t

The planned capacity is 20 GWh, delivered over four phases; the company expected to reach 5 GWh by mid‑2024. However, there is no public confirmation that this target was met by that date, and current reporting simply restates the original planning figure.

Gotion has entered partnerships with European firms, including BASF China, ABB, Ebusco, Ficosa and Idneo, to support battery materials, energy storage system deployment and technology R&D. It has also established an R&D collaboration with the University of Göttingen in battery materials and system optimization.
