The electric drive is a double blessing. It will enable
When it comes to electrification, the focus is on the contrasting pairs of ‘innovation and tradition’ and ‘performance and suitability’ for everyday use. With every new model generation, the sports car manufacturer once again demonstrates its outstanding engineering achievements. The company principle "Perform much, consume little" should be raised to the next level at every juncture.
In addition to costs, the most critical factors for the breakthrough of electromobility are the range and availability of sufficient infrastructure. Practical experience shows that the majority of currently available electric vehicles are designed as commuter vehicles or for use in city centres. In most cases, frequent recharging is necessary and the driving performance rarely meets the usual user requirements. Even during long charging processes, for example overnight or during working hours, the range gained remains manageable due to the current relatively low battery capacity. The 800-volt technology, which is being strongly promoted by
For long distances that need to be covered in as short a time as possible, waiting times for the charging process are very pronounced and are usually unacceptable to the consumer. In order to keep the charging process brief, a high charging capacity is required. Corresponding AC charging systems are no longer suitable for installation in vehicles, due to their weight and dimensions. For this reason, at this point high-power charging systems that convert from alternating to direct current in the charging station are used. The heavy high-current charger is not required inside the vehicle. Only the necessary safety and monitoring unit remains.
A suitably designed high-power charging infrastructure must accommodate the usual user behaviour on long journeys and enable a convenient ratio of journey time to break time. Within the usual break times of 15 to 20 minutes, power is recharged for a range of around 400 kilometres.
Raising the voltage level of the infrastructure to 800 volts enables a significant reduction in charging time. Even on the basis of the currently available cell chemistry, charging times that fit easily into the travel profile of long-haul journeys are possible. Evaluation of the necessary technology shows that this infrastructure can be technically implemented. Economic efficiency is also apparent in relation to the customer benefit for operators and users.
* Data determined in accordance with the measurement method required by law. Since September 01, 2017 certain new cars have been type approved in accordance with the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), a more realistic test procedure to measure fuel consumption and CO2 emissions. From September 01, 2018 the WLTP will replace the New European Driving Cycle (NEDC). Due to the more realistic test conditions, the fuel consumption and CO2 emission values determined in accordance with the WLTP will, in many cases, be higher than those determined in accordance with the NEDC. This may lead to corresponding changes in vehicle taxation from September 01, 2018. You can find more information on the difference between WLTP and NEDC at www.porsche.com/wltp.
Currently, we are still obliged to provide the NEDC values, irrespective of the testing method used. The additional reporting of the WLTP values is voluntary until their obligatory use. As far as new cars, (which are type approved in accordance with the WLTP) are concerned, the NEDC values will therefore be derived from the WLTP values during the transition period. To the extent that NEDC values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. They are intended solely as a means of comparing different types of vehicle. Extra features and accessories (attachments, tyre formats etc.) can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics. Additionally, weather and traffic conditions, as well as individual handling, can affect the fuel consumption, electricity consumption, CO₂ emissions and performance values of a car.
