Spacious and locally free from emissions: in addition to electric cars, vans with electric drives have long since entered the vehicle market. Almost all manufacturers now also have electric vans in their range. For one of them, the Leadec team at the Hoyerswerda site takes over the repair of batteries from Europe centrally in the event of a defect.
Sustainable and resource efficient
When the defective battery arrives at the factory in Hoyerswerda, the team repairs it within a short time, starting with the evaluation of the battery and the reading of the error code and failure analysis. The repair process depends on the result of these steps.
A lithium-ion battery has a modular design and can also be repaired accordingly. If, for example, a failure of individual cells is diagnosed, it is often sufficient to replace the affected module. Other defects – be it a defective battery management system or the failure of electrical components such as current sensors – are repaired by the specialists in Hoyerswerda. After successful repair, the battery undergoes end-of-line testing, where it is once again put through its paces before being returned to the customer.
Repair thus plays a central role in the battery cycle. It is not only cheaper than producing new batteries, but it also conserves resources, thus making the battery a little more sustainable. After all, it is also the most resource-intensive component of the e-vehicle.
When handling a high-voltage battery that is still live despite a defect, special safety precautions must be observed, and special qualifications must be demonstrated. Due to the expanded range of services, four additional employees have been trained and are now specialists for batteries, electrical and live working.
