It’s getting closer to the premiere of the new and electric version of the Porsche Cayenne, and we’ve already checked out and taken a ride in the new performance SUV, which you can read more about here. We also know from before that the Cayenne Electric will be offered with a charging plate that makes it possible to charge the car wirelessly with up to 11 kW. We have also checked that, and you can find more about it here.
Now Porsche releases even more details about the technology of the battery and charging. The battery pack is 113 kWh and has a new design that makes it a load-bearing part of the car’s structure. The battery consists of six modules that are mounted directly in an aluminum frame. In each of the modules there are 192 pouch cells that were developed in collaboration with LG Energy Solutions and have NMCA chemistry, i.e. nickel-manganese-cobalt-aluminum, and a graphite anode with six percent silicon oxide. According to Porsche, it provides seven percent higher energy density than the battery used by the Taycan, while the new chemistry makes it possible to increase the charging power.
That, together with double cooling plates above and below the battery, allows the Porsche Cayenne to charge with up to 400 kW. With it, it is possible to fill the large battery from 10 to 80 percent in 16 minutes. In 10 minutes it should be possible to squeeze in energy for a range of 30 miles. A charge curve has not yet been shown, but Porsche writes that the Cayenne Electric maintains an output of between 350 and 400 kW up to 50 percent of the state of charge. If the Cayenne Electric is connected to an older 400-volt charger, it can be charged with up to 200 kW.
According to Porsche, the cooling system has the same capacity as 100 ordinary refrigerators. In addition to the cooling plates, what are described as pressure fans are used to dissipate heat, a technology that according to Porsche draws 15 percent less energy than traditional suction fans.
To optimize the preheating of the battery before charging, the Predictive Thermal Management system is launched with the Cayenne Electric. Based on the route, topography and driving style, the preheating on the way to the charging post is adapted.
Exactly when it is time for the premiere of the Porsche Cayenne Electric is not revealed, but according to Porsche it will happen “in a few weeks”.
