The all-electric Cayenne will soon be added to Porsche’s SUV portfolio. It is based on an evolution of the Premium Platform Electric (PPE) developed in-house. Its 800-volt architecture creates the basis for impressive charging power, intelligent energy distribution and high efficiency.

In combination with the new drive system, the Cayenne Electric achieves range figures equally suitable for everyday use and long-distance journeys. The Cayenne Electric prototype has recently displayed its long-distance capability. Several independent US journalists subjected near-production but still camouflaged prototypes to a highway range test and drove more than 350 miles (563 km) on a single battery charge at a maximum permitted speed of 70 mph (113 km/h)^#.

The vehicle’s range performance is the result of the combination of innovative technology and sophisticated energy management. “With the Cayenne Electric, we are taking e-performance to a new level,” explains Dr Michael Steiner, Deputy Chairman of the Executive Board and Member of the Executive Board, Research and Development. “Our innovative high-voltage system combines maximum efficiency with the driving dynamics typical of Porsche.”

Integrated HV battery: safe, compact, efficient

At the heart of the Cayenne Electric is a function-integrated high-voltage battery with a gross energy content of 113 kWh. It is directly integrated into the vehicle structure and, in addition to storing energy, also acts as an integral structural component. This results in significant advantages in weight and packaging; the ratio between cells and battery housing has improved by 12 per cent compared to the second-generation Taycan battery. Integration of the battery into the body structure also increases vehicle rigidity and further lowers the car’s centre of gravity – both essential factors for driving dynamics and precision. The battery therefore contributes to the agile handling of the Cayenne Electric. Porsche is also setting new standards in the field of passive safety; the battery modules are made of a specially developed aluminium profile that absorbs energy in a targeted manner and protects the cells in the event of an impact.

Cell chemistry and energy density: peak efficiency

For maximum energy density and charging capability, Porsche uses a lithium-ion battery with six interchangeable modules and 192 large-format pouch cells. The cells consist of a graphite-silicon anode and a nickel-manganese-cobalt-aluminium cathode (NMCA). The high nickel content of 86 per cent ensures maximum energy density, while silicon in the anode significantly enhances the fast-charging capability. Aluminium increases the rigidity of the cell structure. The result: seven per cent higher energy density compared to the current Taycan battery, while also increasing charging efficiency.

Double-sided cooling: the key to sustained performance

A key element of the high-voltage system is the innovative cooling system, which regulates the temperature of the battery from both above and below. This dual cooling allows precise control of the temperature window and ensures that the battery always operates in the optimal range – regardless of the weather, charging power or driving style. The cooling capacity corresponds to that of about 100 large household refrigerators. For the first time, energy-efficient pressure fans will be used, which consume around 15 per cent less energy than conventional suction fans. The result is a consistently high charging capacity and high performance with minimal energy loss – a key element of the overall efficiency of the new Cayenne.

Predictive thermal management: thinking ahead

The new Predictive Thermal Management is an integral part of the electrical architecture of the Cayenne Electric. It links all of the vehicle’s cooling and heating circuits, continuously analyses temperature, route and driving profile, and proactively controls the flow of energy. While driving, intelligent software calculates the heating or cooling requirements in real time – taking into account navigation data, topography, traffic conditions and driving behaviour. The aim is to keep the battery in the optimum temperature window at all times – for maximum charging speed, service life and range consistency. The advantages for the driver include shorter charging times, lower energy consumption and even more accurate range predictions. The system works closely with the further-developed Charging Planner, which takes individual charging preferences into account and preconditions the battery for the next stop while driving.

“The function-integrated battery, the double-sided cooling concept and the predictive thermal management demonstrate how we think comprehensively about technology,” says Dr Michael Steiner. “Our aim is to provide electric mobility in a way that befits Porsche – efficient, powerful and engaging at the same time.” 

Robust fast-charging behaviour: next-level usability

The Cayenne Electric sets new standards in charging performance. Its capacity of up to 400 kW at suitable high-power charging stations enables charging from 10 to 80 per cent in less than 16 minutes. The Cayenne Electric maintains this high level of charging power over an exceptionally wide state of charge band. Up to about 50 per cent SoC, the charging rate consistently remains between 350 and 400 kW – a clear benefit for long-distance driving^.

This optimal fast-charging curve is achievable from a battery temperature of just 15 degrees Celsius, which is significantly lower than before. This means that the car’s charging performance is particularly robust under real-world conditions throughout the year. In addition, the 800-volt architecture combined with the high-voltage switch in the battery also enables efficient charging at 400-volt stations at up to 200 kW – without an additional booster.

Porsche Wireless Charging: cable-free convenience

From 2026, Porsche expects that it will offer the new Porsche Wireless Charging system – an 11 kW wireless charging system with a compact one-box floor plate – for the first time with the Cayenne Electric to select markets, although AUstralia is yet to be confirmed. This contactless charging technology achieves a similar efficiency to wired AC charging: up to 90 per cent. When parked over it, the vehicle automatically detects the floor plate and lowers itself slightly for charging. The inductive charging process takes place across a gap of a few centimetres. The entire process is fully automatic, safe and maintenance-free. The My Porsche app can be used to monitor charging processes, define time slots or authenticate several vehicles. With this technology, Porsche is once again emphasising that efficiency and convenience go hand in hand – even when charging.

Actual range you experience will vary depending on a number of factors such as speed, traffic and weather conditions, driving habits, elevation change, how much weight the vehicle is carrying, use of vehicle features/accessories such as heating or air-conditioning, and wheels/tyres among others. Please contact an Official Porsche Centre for information regarding Australian delivered models.

^ Charging times are based on rates observed during Porsche AG testing on a test vehicle in
controlled test conditions using a high speed DC charger for vehicle comparison purposes only. The rates of charge you experience will differ depending on a number of factors such as the ambient conditions, battery size, the amount of charge the battery has and the type of charger. Public DC chargers are typically faster than AC chargers installed at residential premises. We recommend charging to 80 per cent to assist in maximising your vehicle’s battery range and battery life over time.
