Charged EVs | Porsche Cayenne Electrical’s 800-volt structure allows lengthy vary and super-fast charging

Porsche’s Cayenne Electrical SUV, which will likely be launched in a couple of weeks, relies on a brand new model of the corporate’s Premium Platform Electrical, and options numerous improvements, together with a function-integrated battery, a twin cooling system, clever thermal administration and an 800-volt structure.

In line with the mixed WLTP normal, the brand new SUV could have a variety of greater than 600 kilometers. A number of US journalists lately took near-production prototypes out for a freeway vary take a look at and drove greater than 350 miles (563 km) at a most permitted velocity of 70 mph (113 km/h).

The Cayenne Electrical’s battery pack has a gross vitality content material of 113 kWh. It’s straight built-in into the automobile construction, so along with storing vitality, it acts as a structural part. Porsche explains that this yields vital benefits in weight and packaging—the ratio between cells and battery housing has improved by 12 p.c in comparison with the second-generation Taycan battery. Integration of the battery into the physique construction additionally will increase automobile rigidity and additional lowers the automotive’s heart of gravity. The battery modules use a specifically developed aluminum profile that absorbs vitality in a focused method and protects the cells within the occasion of an impression.

The battery pack consists of six interchangeable modules and 192 large-format pouch cells. Every cell features a graphite-silicon anode and a nickel-manganese-cobalt-aluminum (NMCA) cathode. The excessive nickel content material of 86 p.c boosts vitality density, and silicon within the anode enhances quick charging functionality. Aluminum will increase the rigidity of the cell construction. The result’s seven p.c larger vitality density in comparison with the present Taycan battery, plus elevated charging effectivity.

An modern cooling system regulates the temperature of the battery from each above and beneath. This twin cooling permits exact management of the temperature window and ensures that the battery at all times operates within the optimum vary. The system, which boasts cooling capability equal to 100 massive family fridges, options energy-efficient stress followers, which eat round 15 p.c much less vitality than typical suction followers.

The brand new Predictive Thermal Administration characteristic hyperlinks all of the automobile’s cooling and heating circuits, repeatedly analyzes temperature, route and driving profile, and proactively controls the stream of vitality. Whereas driving, clever software program calculates the heating or cooling necessities in actual time. The purpose is to maintain the battery within the optimum temperature window always.

The Cayenne Electrical can take as much as 400 kW of charging energy at appropriate DC charging stations, and the corporate says it maintains this excessive degree of charging energy over an exceptionally broad state-of-charge band. As much as about 50 p.c SoC, the charging price persistently stays between 350 and 400 kW.

The 800-volt structure mixed with the high-voltage swap within the battery additionally allows environment friendly charging at 400-volt stations at as much as 200 kW.

Beginning in MY 2026, Porsche will supply the brand new Porsche Wi-fi Charging system—an 11 kW wi-fi charging system with a compact one-box flooring plate.

“With the Cayenne Electrical, we’re taking e-performance to a brand new degree,” mentioned Dr. Michael Steiner, Deputy Chairman of the Porsche Govt Board. “Our modern high-voltage system combines most effectivity with the driving dynamics typical of Porsche.”
