Quality assurance
From incoming goods to delivery to our customers: An overview of our excellent processes for ensuring product quality
We are convinced that the service provided by our technical and warehouse departments far exceeds the standard and guarantees you outstanding product quality. To this end, we have developed state-of-the-art, partly automated processes that put our goods through rigorous testing. Feel free to explore the videos and information about our services and let our Managing Director Kai Kutter give you deeper insights into these topics.
Incoming goods inspection
When a delivery arrives by container, the incoming delivery note is scanned at the inspection table and the silkscreen and weight of the battery are checked. The weight is automatically transferred to our system and the Hioki is used to measure the internal resistance and volts.
In addition, all products are tested for performance and partially stored temporarily in order to undergo new ageing tests after 2–3 months.
Water bath and temperature chamber
We regularly check the standard of our products to ensure that we can always offer our customers top quality.
For this purpose, we use a water basin to test the longevity of our batteries. This allows us to verify whether the EUROBAT service life stated on the batteries is correct.
For further testing, we have a temperature chamber in-house, allowing tests to be carried out within a range of -80 °C to +180 °C. Various materials – such as lithium battery packs and lead batteries – can be tested in different spheres. During this process, the products are charged and discharged while monitoring whether the batteries switch off correctly at the designated points. In addition, the endurance of the materials used is analysed.
Service testing using a modern cloud-based solution
Before delivering our products, we carry out extensive tests on each individual module to ensure that full capacity is available. We also verify that all communication functions operate correctly and that all cells in the memory are properly balanced. This is important to ensure consistent performance.
The innovation lies in the fact that we fully cycle all systems in advance for specific customers. With a modern cloud solution, it is possible for us to monitor and analyse the voltage of each individual cell at module level. As soon as a cell deviates by 0.05 volts from the average of all other cells, the device sends a red signal. In Germany, only very few manufacturers offer this special service of carrying out a thorough final analysis of the modules in detail before the large-scale systems go into operation.
This analysis allows us to verify whether the modules can consistently maintain their full quality. Although this individual testing is already carried out in Asia beforehand, we repeat the test here in Germany to ensure that the specified data matches, the batteries perform as expected, and we can deliver top quality to our customers.
Our new finishing hall
As we have already reported in our energetic company news, we have acquired a new warehouse at our site in Norderstedt. Our new, modern finishing hall has now been built on this new 500 square metre site.
The finishing hall is now fully equipped and forms the basis for the automation of the top charging process. Our employees from the technology and logistics departments are constantly optimising this process by independently developing procedures and suitable accessories to make the process even more efficient.
The new hall has increased our capacity by around 300% – from up to 300,000 batteries, which we were able to recharge to full capacity in the old charging hall, to around 1.2 million now. This means that we can continue to offer you the best top charging service despite increasing order volumes.
This service is unique and is particularly popular with customers in the UPS industry. The homogenised batteries, whose cell voltages have been adjusted, are ready for immediate use thanks to multiple testing and top charging after delivery.
The inspection service provided by our technical department
Our technical department ensures continuous inspection of our products – whether it’s checking incoming goods from Asia or handling your complaints. Feel free to take a look at the tour with our Managing Director Kai Kutter, and let him walk you through our processes in the technical department.
