The Ruhr University Bochum is responsible for the operation of a variety of stationary battery systems located on campus as well as at various external properties, contributing to the uninterruptible power supply (UPS) of sensitive technical systems. To ensure the safety, functionality, and availability of these battery systems, regular maintenance is carried out in accordance with the specifications of DIN VDE 0510, DIN EN 50272, the Operational Safety Regulation, as well as internal technical standards. This includes both periodic visual and functional inspections, as well as an annual load test under real operating conditions. As part of these measures, all relevant parameters such as voltage, internal resistance, acid density, and temperature are systematically recorded, documented, and evaluated. Additionally, all safety-related facilities such as catch basins, ventilation systems, and eye wash stations are inspected and documented. The collected data is digitally documented, supplemented with photographic evidence, and forwarded to the relevant authorities. These regular inspections and maintenance work are essential to ensure safe and trouble-free operation of the battery systems and to identify and address potential risks such as failures, technical defects, or safety-critical conditions at an early stage. This tender describes the detailed requirements and services necessary to ensure the specified testing, maintenance, and documentation processes. The described services are to be performed by qualified third-party providers in the future, to ensure continuous compliance with technical and safety-relevant standards. The Ruhr University Bochum intends to secure the quality, safety, and operational continuity of the battery systems sustainably through this tender and thus contribute to the protection of the energy supply of critical infrastructure.
