Automation solutions from Rexroth for the production of modern energy storage

energy storage

For economical, flexible battery production, Bosch Rexroth offers trusted dry room and cleanroom-compatible solutions as a partner for automation solutions.

Efficient production from the cell to the battery pack through a high degree of automation and standardization

Renewable energies and electromobility are becoming increasingly important and necessitate powerful storage systems. The economical use of modern energy storage units requires the use of efficient, cost-effective production – from the electrode to the finished battery pack. Because these processes demand a high degree of quality, automation and standardization are decisive factors. They are also important for the means of production which have proven themselves in both dry rooms and cleanrooms. As an automation partner, Bosch Rexroth offers tried-and-tested solutions, such as transfer systems and tightening technology, to meet the challenge of battery production.

Production processes performed in dry rooms and cleanrooms significantly impact the lifespan and energy density of energy storage units. The exceptionally low level of humidity in dry rooms has an immediate impact on the production means employed: plastics quickly become brittle, and even lubricants and sealants have to be acclimatized to the dry air. The cleanroom classification specifies that particles have to be smaller than 10 µm in order to prevent interference with the cells' capacity and lifespan.

Bosch Rexroth offers qualified means of production for dry room and cleanroom production based on well-founded materials expertise acquired over decades of experience. This allows all transport tasks in battery production to be solved using Rexroth transfer systems. For example, the TS5, which has long been used in the automotive industry, can handle heavy loads commonly associated with battery pack assembly. The transfer systems run problem-free, even with a humidity of less than 1%, and are certified for ISO Class 6 cleanrooms because smooth surfaces, internal connection technologies, and abrasion-resistant toothed belts eliminate particle traps.

Another key aspect is process quality optimization for ensuring the long lifespan and high energy density of the energy storage unit. At the same time, precise, flexible equipment constitutes the basis for the economically necessary high output levels and quick reactions to changing customer requirements. Standardized Rexroth tightening systems make a decisive contribution to this flexibility and production safety. For handheld nutrunners, specialists have developed retrofittable battery assembly kits that offer users maximum safety and freedom of movement, even for small or changing battery production batch sizes. Specially developed insulated drives simultaneously protect the user, as well as the nutrunner and the environment, from potential battery voltage.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, Factory Automation, and Renewable Energies to develop innovative components as well as tailored system solutions and services. Bosch Rexroth offers its customers hydraulics, electric drives and controls, pneumatics, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, more than 37,500 associates generated sales revenue of approximately 6.5 billion euros in 2012.
