Technology for battery test benches: precise measurement, full control
Battery test benches are essential tools for the development, quality assurance and maintenance of modern energy storage systems such as batteries, rechargeable batteries and fuel cells. They enable reliable testing under realistic conditions, particularly in sectors such as the automotive industry, renewable energies and electronics technology. The combination of modern testing technology and intelligent automation also offers numerous advantages for your company.
What advantages does a battery test bench solution with Delphin offer you?
- High measurement reliability due to galvanically isolated channels: The complete separation of the measuring channels reliably prevents unwanted currents or cell short circuits - a decisive contribution to operational safety in high-energy tests.
- Scalable test architecture for parallel processesMultiple test processes can be operated independently of each other - ideal for increasing test throughput and efficient utilization of test capacities.
- Autonomous recording and control of test processesThe systems work independently of a central PC - this enables stable operation even with applications that are remote from the network.
- Simple implementation of complex test sequences: Test sequences can be structured logically and modularly - this enables reproducible results and a high level of automation, even in demanding test scenarios.
- Reliable monitoring with high energy densityIntegrated protection and monitoring functions ensure the test sequence even with high electrical loads - for greater stability, fault detection and device protection.
Battery test benches are an indispensable tool for the development, production and maintenance of batteries. Typical areas of application are
- Service life testing of tool batteries
- Discharge and charging tests
- Temperature measurement
- Battery capacity measurement
- Determining the efficiency of fuel cells

Safe and scalable testing technology for lithium batteries
A manufacturer of industrial lithium batteries relies on a modular test system to test up to 90 battery cells simultaneously and efficiently. The test specimens are divided into up to 30 groups, which can be configured independently of each other and started with a time delay - ideal for flexible test series with high throughput. The measuring systems used ProfiMessage D work with galvanically isolated differential inputs, which guarantees feedback-free and safe voltage detection - particularly important for high energy densities. Short circuits and measurement faults are reliably avoided. The test sequences, including defined discharge cycles, have been automated by the user. During the tests, the system continuously records voltage curves, currents and time marks. The data is automatically used to generate ProfiSignal software The system calculates characteristic values such as the discharge capacity and documents them graphically and in tabular form in standardized reports. The result: a reliable, safe and flexibly expandable testing system for quality assurance of lithium batteries on an industrial scale.
