Batteries for new Porsche Cayenne to be produced in-house

For the new gen of the Cayenne, Porsche has said that it will be using high-voltage batteries developed and manufactured entirely in-house.

Together with Porsche Werkzeugbau GmbH, in the Slovakian town of Horna Streda, the brand has established the Porsche Smart Battery Shop - a state-of-the-art production facility for the next generation of battery modules. The facility has been expanded into an innovative technical centre and is also where the new Cayenne Electric's battery modules will be produced in the future.

The state-of-the-art module production facility carries out real-time process data acquisition, which guarantees full transparency and control at every stage of production

Construction of the production hall began in January 2023, with installation of the production equipment began in September of the same year. Thanks to the intensive collaboration between those responsible for technical development in Weissach and production planning in Zuffenhausen, the project was completed in record time. In May 2024, the facility produced its first finished module.

The facility also carries out real-time process data acquisition, which guarantees full transparency and control at every stage of production. Before a battery module leaves the factory, all quality criteria are checked, and all production data is securely archived in the cloud. This means that each module that is signed off has been subject to continuous quality control as it made its way through the manufacturing process.

At the facility, newly produced batteries are validated under laboratory conditions in Porsche's own analysis centre

In addition to product quality, Porsche also checks the performance of the battery - in particular relating to its longevity and charging capability. To this end, newly produced batteries are validated under laboratory conditions in the company's own analysis centre - as are related components that currently still come from test vehicles.

To ensure that the high-voltage battery meets Porsche's exacting quality standards, extreme conditions are simulated - such as heat exposure from 60 to 100 degrees Celsius - and an immersion test is carried out.

The Smart Battery Shop is committed to environmentally friendly solutions and aims for a high level of self-sufficiency. By using photovoltaic elements to harness renewable energy and heat pumps for efficient energy supply, it contributes to reducing CO₂ emissions and promoting local climate protection.

In addition, as a contribution to climate resilience, the factory's roof surfaces are greened, and the site has its own well for water supply.
