A Second Life for the Battery

The battery is the heart of an electric vehicle: not only is it the most important component, but also the most expensive, raw material-intensive one. An intelligent battery management system usually ensures a long life. Nevertheless, a defect cannot be ruled out. In such a case, however, the battery does not have to be recycled directly – the alternative is to repair it. This is exactly what is done at the Leadec Hoyerswerda site.

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.


Safety first

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.

Expertise in the battery segment

In recent years, the Leadec site in Hoyerswerda has made a name for itself in the industry in the field of battery production. Since 2019, a team of over 100 has been providing services such as pre-assembly, leak tests, corrosion protection and logistics, including the storage of up to 20,000 batteries, right through to repair and dismantling.
