Porsche tightens grip on battery production for Cayenne Electric after early Taycan quality issues

Porsche is increasing its direct oversight of battery manufacturing for the forthcoming Cayenne Electric, expanding in-house module assembly after encountering quality problems during the early production phase of the Taycan, the company’s first all-electric model.

Battery modules built in Slovakia with 370 robots on two shifts

The modular battery production is being carried out at Porsche Werkzeugbau in Horna Streda, Slovakia, where 150 employees working across two shifts, supported by 370 robots, can produce up to 132 modules per hour.

Six-module pack and supply chain split across Slovakia and Germany

Each Cayenne battery pack is made up of six modules, a rate that in theory could equip up to 352 vehicles per day. Final assembly of the battery-integrated with the power electronics-is handled by Webasto at a site near Bratislava, while the electronics are supplied by Germany-based Marquardt.

Porsche said the project moved from the start of plant construction in 2023 to the production of the first module in 18 months.

Battery becomes part of the car’s structure and safety concept

According to Porsche management, the battery is designed to be integrated into the vehicle’s load-bearing body structure and also serves a safety function. The company added that, where it has the expertise, it prefers to keep control of key technologies rather than outsource them entirely.

Cayenne Electric details: first discussed in November 2025, 850 kW Turbo and 600 km-plus range

Porsche first spoke publicly about the Cayenne Electric in November 2025. A Turbo version is rated at up to 850 kW (1,156 hp), which Porsche says would make it the most powerful series-production model in the brand’s line-up.

The vehicle’s 113 kWh battery is claimed to deliver a WLTP range of more than 600 km, and it supports 800-volt fast charging.

Electric Cayenne joins petrol, diesel and plug-in hybrid options; German pricing from €105,200

The new Cayenne is set to broaden Porsche’s range while the brand continues to offer internal combustion and plug-in hybrid variants. In Germany, the electric model is priced from €105,200.

Porsche says the 2026-model-year line-up reflects its broader strategy of developing battery-electric vehicles alongside more traditional powertrains.
