Porsche's first pure electric vehicle, which was born last year as the Mission E, has been undergoing various driving tests this year under the name 'Taycan'.
In particular, the high-speed long-distance driving test conducted in Nardius, Italy in August demonstrated three aspects: driving stability as an electric vehicle, easy and fast charging technology, and efficient heat management.

The long-distance drive, with a total distance of 3,425 km, was conducted at an average speed of 195 km/h to 215 km/h, and in temperatures that ranged from 42 degrees Celsius to a high of 54 degrees Celsius.

The double-drivable section lasted a total of 24 hours without interruption, excluding sections for battery charging and driver changes, Porsche test officials said.
Porsche's electric car, the Taycan, is scheduled to be released in September of this year.The company aims to complete a total of 6 million kilometers of testing before launch, and more than 60 developers are currently conducting final testing to complete a stable 440kW (600 horsepower) system output.

800V base, 400km range with 15 minutes of charging
Porsche plans to invest approximately €600 million in electric mobility by 2020. This investment addresses battery efficiency, a key issue in electric vehicles, and safe, fast-charging technology.

Porsche's electric vehicles, particularly those with a sports car concept, must possess a battery structure that is as lightweight and efficient as possible, unlike conventional vehicles. The battery currently installed in the Taycan is a 270Wh/kg lithium-ion high-voltage battery.

However, the correlation between maximum driving range and total weight of the battery pack for high-efficiency battery use needs to be resolved. Additionally, the application of battery monitoring technology for temperature and stable operation, which are unique to lithium batteries, appears to be one of the areas that must be continuously developed even after launch.

Charging stations for fast charging will be installed in 10 major locations across the country, with 320kW ultra-fast chargers and slow chargers installed in approximately 120 locations.
The 800V charging pole presented by Porsche is compatible with basic 400V vehicles and can be used for 400km of driving with a 15-minute charge.

Efficient thermal management technology for instant charging while driving
There is a direct correlation between high-speed driving of electric vehicles and vehicle heat. If a high-temperature battery caused by driving is immediately fast-charged, the battery heat generated during charging can directly lead to a vehicle fire.

These issues also lead to vehicle charging being isolated through battery monitoring during charging.

To address these issues, Porsche has implemented a high-speed heating and cooling system that reaches the optimal temperature during charging, using an intelligent charging protocol and an efficient heat exchange system, enabling the car to be charged for 400 km of driving in just 15 minutes.

The test, which took place at the Nardius Technical Center in Puglia, Italy, which has more than 20 test tracks and facilities for Porsche's first electric sports car, the Taycan, was conducted by Porsche Engineering Group GmbH.
