Porsche Opts for New Battery Architecture and Cell Chemistry in Cayenne

With its new Cayenne E4 model, Porsche has introduced a revised battery architecture based on a module-to-car approach with six large-format modules being integrated into a subframe. The company claims this design reduces weight, simplifies repairs, and creates more flexibility in the vehicle layout.

Advanced NMCA cathode

For the first time, Porsche is using pouch cells which combine a silicon oxide graphite anode with an advanced nickel-manganese-cobalt-aluminum (NMCA) cathode. The high nickel content of 86 percent increases energy density, while aluminum ensures improved stability and service life. Despite its higher energy density, the battery with a gross capacity of 113 kilowatt-hours and a net capacity of 108 kilowatt-hours is more compact than the one in the Taycan model.

Optimized thermal management

A key feature is the thermal management system, which uses cooling plates to regulate the temperature on both sides of each cell. This is to ensure even temperature distribution, to stabilize power output, and to enable high charging and discharging currents. The technical innovations have a direct impact on charging performance: The Cayenne E4 achieves a peak output of up to 400 kilowatts and is said to be able to charge from ten to 80 percent in less than 16 minutes. The 800-volt technology remains backward compatible with 400-volt chargers, which increases its practicality. With the combination of new cell chemistry, innovative pack architecture, and optimized thermal management, Porsche is addressing key requirements for future high-performance batteries: longer range, shorter charging times, and improved long-term stability.
