In fact, performance and energy saving do not conflict. Analysis of Porsche Electrification Technology

[Sohu car · high beam] (text: Cao Hao/figure: Porsche official & Network/: Peng Zhao) in people's traditional cognition, when cars are added with electrification system, it will bring energy saving and reduce pollution. In fact, what others don't know is that cars with electrification system will also show another effect, that is, the pursuit of vehicle performance. How to achieve the ultimate performance under the premise of energy conservation and environmental protection is also the pursuit of brands like Porsche that are good at performance

in fact, since the launch of the new flagship sports car 918 Spyder in 2013, Porsche has been showing us its powerful electrification technology. What they show is not only the unremitting pursuit of extreme performance. Since then, in 2014, Porsche began to transplant the electrification technology that appeared on the 918 Spyder to mass-produced vehicles, resulting in the Panamera and cayenne plug-in hybrid models we have seen so far

[· 1. History should start more than 100 years ago]

if we want to talk about the historical process of Porsche electrification, we need to start more than 100 years ago. Although the Porsche brand was officially established in 1931, as the founder of Porsche, Mr. Ferdinand Porsche built the first hybrid car in history - lohner Porsche "Semper vivus" in 1900

in fact, the first lohner Porsche is a pure electric product. All the energy comes from a set of lead-acid batteries weighing up to 1.8 tons, but the two hub motors located in the front wheel can only provide the maximum power of nearly 3 horsepower respectively. For such a heavy car, the horsepower is completely insufficient to support the driving of the vehicle, so Ferdinand later tried to install hub motors on all four wheels, Thus, the first four-wheel drive vehicle in the world was formed

however, even if the four hub motors only rely on the electric energy provided by the heavy and clumsy lead-acid battery to drive, although the innovative UK/yasa project focuses on the electromechanical rotor driven vehicle of passenger cars, the vehicle may have run out of electricity before it has driven far, so Ferdinand can only find another way to use a typical series system to connect the engine to the hub motor, Let the wheel battery no longer rely solely on lead-acid batteries to drive, so it is not only guaranteed in the vehicle power, but also the number of batteries installed on the vehicle is reduced from 74 to 44. This is the world's first hybrid car

two water-cooled gasoline engines are installed in the middle of the car body. Each 3.5 HP gasoline engine drives two generators respectively, and the 2.5 HP generator provides power for the hub motor, while the excess power flows into the battery pack for storage. The generator in turn can be used as the starter of the engine. Therefore, lohner Porsche "Semper vivus" is also regarded as the prototype of hybrid electric vehicles, which is about a century earlier than today's hybrid electric vehicles

[· 2. Hybrid cars will be launched in more than 100 years]

in fact, no one expected to see Porsche's hybrid cars again in more than 100 years. In 2013, Porsche's new flagship sports car 918 Spyder was born. As the flagship model of the Porsche brand known for its performance, the performance of the vehicle must be unparalleled. However, in the 918 Spyder, the way Porsche uses to improve its performance is not to increase the engine displacement, which is often used before, but to add a plug-in hybrid system, which is also the first time that a hybrid system has been added in the super sports car level

the Porsche 918 Spyder adopts a plug-in hybrid system composed of a 4.6l V8 engine and two motors on the front and rear axles. Due to the existence of motors, the most unique concept of all wheel drive at that time was formed. The front motor is 95kw, the rear motor is 115KW, and the maximum power of the system is 652kw. Such power output also makes the 918 Spyder the first mass production vehicle running within 7 minutes in the north ring of Nurburgring

[· 3. Mass production of Electrification Technology]

when it comes to mass production of electrification technology by Porsche, we still need to go back to 2010, when the 918 Spyder concept car was unveiled. In that year, the first hybrid model of Porsche, the Cayenne S hybrid, was launched, while in 2011, the Panamera s hybrid was launched. However, both of these two models are powered by hybrid electric vehicles, but today's Porsche has abandoned the use of hybrid electric technology, Instead, it uses its proprietary high-performance polymer 3D printing material W on the 918 Spyder. When the runner finishes drinking the water in the seaweed bag, indform XT 2.0 material has passed the successful plug-in hybrid technology of the screening outgassing test of the European Space Agency (ESA)

the newly launched Panamera Turbo S e-hybrid model is equipped with a plug-in hybrid system composed of a 4.0L V8 engine and an electric motor, which is matched with an 8-speed PDK dual clutch transmission. The maximum output power of the system is 680 HP and the peak torque is 850n · M. The lithium-ion battery pack with a capacity of 14kwh can use about 11kwh, and can provide a pure electric mileage of up to 50km. Such a power combination can not only provide 3.4 seconds of km/h acceleration performance, but also reduce the fuel consumption per 100 kilometers to only 2.9L, which can be said to give full consideration to performance and fuel economy

in addition, Porsche has also launched the new Panamera Turbo S e-hybrid sport turbomo, which is basically the same in performance as the new Panamera Turbo S e-hybrid, but it is the first time that Porsche has taken the plug-in hybrid model as its flagship model

like Panamera, cayenne has also become an option for mass production of Porsche electrification technology. The new Cayenne e-hybrid adopts a combination of 3.0L V6 engine and motor. The maximum output power of the system is 462 HP, the peak torque is 700n · m, and the acceleration of 100 kilometers takes only 5 seconds, while the average fuel consumption can be as low as 3.2l. The lithium-ion battery pack has a capacity of 14.1kwh, which can provide Cayenne e-hybrid with a pure electric range of up to 44km

in fact, both Panamera and cayenne plug-in hybrid models can see the shadow of the 918 Spyder. In fact, this can also be seen as the fact that after the great success of Porsche plug-in hybrid technology on the 918 Spyder, it has delegated its technology to mass production models, so as to provide more mature technology for mass production vehicles. Such an approach may have no precedent in the world, but at least in Porsche, this approach has been successful

[· 4. Another possibility brought by taycan]

at this year's Geneva auto show, Porsche officially released its first pure electric vehicle - the mission e concept car, and the mass production car based on this concept car has also recently been officially named taycan, which will be officially released in 2019

although the final shape of taycan has not been released, it is very likely that it will not be very different from the mission e concept car. The body size will be between 911 and Panamera, and so will the interior space. From the official vehicle parameters, taycan will not disgrace the name of Porsche performance car. The motor output power is more than 600 horsepower, and the km/h acceleration time will be less than 3.5 seconds. At the same time, the vehicle can also provide a range of more than 500km

in addition, another thing of great concern for taycan is that the power battery carried by this car Jinan experimental machine factory shoe material heat resistance tester is mainly used to test the physical properties of high temperature resistance of sole materials. The system voltage will reach 800V, and the advantage of this is that if 800V supporting high-voltage fast charging equipment is used, the time required to charge the mileage to 400km is only 15 minutes. Compared with the 40 minutes required to charge the 400V charging pile to 400km, it shortens the time by nearly two-thirds

[· 5. Summary]

in fact, it is not just Porsche. The future of global car companies will be closely related to electrification. For Porsche, what they need to do is to implement the concept of energy conservation and environmental protection while maintaining performance first. At least from the current situation, Porsche has found a balance. In the future, Porsche will also continue to promote the electrification process, which will not only be reflected in the development of plug-in hybrid models, but also the pure electric mass production vehicle taycan, which will be officially launched next year. According to the plan announced by Porsche, they hope that the carbon dioxide emissions of its models will be reduced by 27% by 2020 from 2013. Subsequently, under the premise of continuous development of electrification technology, carbon dioxide emissions continued to decrease. In addition, according to official news, by 2022, Porsche will invest 6billion euros to develop electrification technology, and focus on the development of plug-in hybrid and pure electric vehicles. From this, in fact, we can see that even a European luxury brand like Porsche, which is nearly a century old, has taken actions to promote the electrification process. How can it be indifferent to a group of Chinese brands
