"Why is the new Macan so efficient at charging?" - Porsche news article

[Tooney]

The process of charging the new all-electric Macan is best described as a symbiosis of user-friendliness and speed, with an unwavering focus on seamless integration of charging into everyday operation.
. . .
Charging capacity of up to 270 kW
The new Macan is the first Porsche to be developed on the basis of the Premium Platform Electric (PPE) developed in collaboration with Audi. Because the sports car reaches a charging capacity of up to 270 kW. Under optimum conditions,* its battery can therefore be fast-charged from 10 to 80 percent in around 21 minutes.
. . .
* What are optimum charging conditions?
CCS quick-charging station with > 320 kW, > 850 V, battery temperature 23°C, and starting state of charge 9 percent
. . .
Bank charging comes into play if the selected station operates with 400-volt technology, with an intelligent software effectively splitting the 800-volt battery into two batteries with the same voltage thanks to built-in high-voltage separators. Both batteries can then be charged at the same time with up to 135 kW at a 400-volt charging station without additional HV booster, making the Macan compatible with charging stations around the world and supporting that it can be used as efficiently as possible by customers. Developed specifically for performance and efficiency, the battery itself contains cells that offer the optimal balance between power density, power content, sustainability, and service life. This is further supported by highly developed thermal management that regulates the temperature of the battery to optimize performance. Circulation therefore provides the necessary cooling when temperatures rise, while in colder months high-voltage components such as the battery can be heated as required by integrating the high-voltage heater.
. . .
“The new Battery Care Mode aims to optimize the service life of the high-voltage battery,” says Gajdos. “If this function is activated by the driver, the target charge level is set to a battery-friendly 80 percent.”
. . .
One of the most important innovative components is the Porsche Integrated Power Box (IPB), for which Porsche has registered a patent. It combines three components: the onboard AC charger, the high-voltage heater, and the 12-volt DC-to-DC converter. Weighing in at just 19 kilograms, the ultracompact IPB is relatively light and is positioned between the rear seat and the battery below to save space. “This packaging optimizes distribution of the vehicle’s weight,” explains Tomas Gajdos. “And it offers more space in the front of the vehicle for a ‘frunk,’ which is another luggage compartment below the hood at the front.”

“… and so now 2 of the components with the highest failure rate have been brought together, and installed in the least accessible location on the vehicle.”
