- The Cayenne Electric uses an 800V system enabling charging up to 400kW and over 600km WLTP range.
- A new 113kWh battery improves structural rigidity, lowers centre of gravity and boosts energy density.
- Dual-sided cooling, predictive thermal management optimise performance, charging speed and efficiency.
Porsche’s first all-electric Cayenne is about to plug into showrooms, bringing a raft of new hardware aimed squarely at making big EVs quicker to charge, more efficient and more engaging to drive.
Built on an evolved Premium Platform Electric (PPE), the Cayenne Electric runs an 800V system that allows brutal charging speeds of up to 400kW and a WLTP range exceeding 600km on a single charge.
During pre-launch testing in the US, camouflaged prototypes reportedly covered more than 563km at highway pace (113km/h) on one go, confirming Porsche’s promises of long-haul credibility.
“With the Cayenne Electric, we are taking e-performance to a new level,” said Dr Michael Steiner, Porsche’s R&D chief. “Our innovative high-voltage system combines maximum efficiency with the driving dynamics typical of Porsche.”
Brains meet volts
At the core lies a 113kWh function-integrated battery that doubles as part of the vehicle’s structure - lightening the pack, stiffening the chassis and dropping the centre of gravity. Its six modular units house 192 pouch cells using advanced graphite-silicon and NMCA chemistry, boosting energy density by seven percent over the Taycan and improving rapid-charge capability.
Porsche’s new dual-sided cooling system keeps the battery thermally balanced from both above and below - akin to 100 household fridges working in sync, helping maintain top performance without energy waste. The system’s new pressure fans also use 15% less power than conventional units, keeping things efficient even when the driver isn’t.
Hot brain, cool battery
Smart software ties it all together. Porsche's Predictive Thermal Management constantly analyses temperature, route, and driving behaviour to pre-empt heat or cooling needs, while the upgraded Charging Planner primes the pack before the next stop.
The payoff: steadier range, quicker charging, and more accurate predictions of both.
The Cayenne Electric’s 800V setup allows a 10 to 80% top-up in under 16 minutes, adding roughly 300km in 10 minutes. Even on 400V stations, it can take in 200kW without a booster.
And for those who’d rather skip the cables altogether, Porsche will roll out an 11kW wireless charging pad in 2026 - an inductive system that hits up to 90% efficiency.
Between the muscle, the smarts and the convenience, Porsche’s biggest EV looks set to make the idea of a long-distance electric SUV sound a little less theoretical and a lot more thrilling.
