Now more and more people around are driving new energy vehicles, and the way to meet and greet people has also changed from "Have you eaten?" It became, "How many kWh of electricity do you have left in your car?" ”
New energy vehicles have become a new choice for travel, can take the bus lane (Xi'an only), environmental protection, 7 cents per kilometer of electricity, green card can also choose a good number, unlimited travel, quiet outrageous, strong acceleration ability, intelligent model platform, etc. may be the reason for choosing new energy vehicles.
Today, Xiaobian will take stock of the 4 major new energy vehicle platforms for everyone to see if your car is on the list.
NO.1 BYD e platform
Bydir e platform is a highly integrated system that even incorporates the central control screen air conditioning control into the modular system, which was officially released to the public in 2018. The core features of the e platform are summarized as "33111", which refers to the modularization and platformization of the five parts of the electric drive system three-in-one, the high-voltage distribution system three-in-one, the integrated body controller, the DiLink intelligent network system, and the high-performance power battery.
After continuous development, BYD's e platform has been platformized by the key technology of 1.0 three electrics and the key system of 2.0, realizing the platformization of the current 3.0 vehicle architecture and giving full play to the advantages of electrification and intelligence. Platform e 3.0 has four characteristics of intelligence, efficiency, safety and aesthetics, which solves the user experience pain points such as safety and low temperature endurance of new energy vehicles, and greatly improves the intelligent driving experience.
It should be known that the three-electric system is the top priority of pure electric vehicles, and BYD e platform 3.0 adopts cutting-edge technologies such as a new generation of SIC electronic control, eight-in-one motor assembly, heat pump technology and motor boost charging architecture. These technologies will allow models based on this platform to have performance indicators such as NEDC endurance exceeding 1000km, 0-100km/h acceleration time of 2.9 seconds, and 150km driving in 5 minutes of charging.
It is worth mentioning that the models created by the e platform 3.0 will all be equipped with blade batteries, and the blade batteries are essentially lithium iron phosphate batteries. Therefore, e-platform 3.0 will be the world's first pure electric vehicle platform based on the 1000 km endurance of lithium iron phosphate batteries.
In order to reduce the maintenance quality of pure electric vehicles, BYD integrates the drive motor, drive motor controller, reducer, high-voltage distribution box, high-low voltage DC converter, on-board charger, vehicle controller and battery manager, which is BYD's eight-in-one electric drive assembly.
And according to BYD's official claim, the e-platform 3.0 standard with a wide temperature range efficient heat pump system can increase the cruising range by 20% in a low temperature environment.
With a range of more than 1000km, 0-100km/h acceleration time of only 2.9 seconds, charging 5 minutes to run 150km, now BYD's three electric technology has been perfect, and the performance indicators even catch up with tesla, the benchmark of electric vehicles. However, advanced three-electric technology is only part of e-Platform 3.0.
Wang Chuanfu, chairman and president of BYD Group, said that the e-platform 3.0 is the product of BYD's integration of knowledge and action for many years, and is the most critical layout of BYD in the transformation of new energy vehicles from electrification in the first half to intelligence in the second half, and is the cradle of the next generation of electric vehicles.
NO.2 Great Wall Lemon Hybrid DHT Platform
For the Great Wall's SUV models, we can use many words to describe, such as: leather, practical, cost-effective, etc., but the three words of low fuel consumption seem to have always been insulated from the Great Wall. After the release of lemon hybrid DHT technology, perhaps one day we will really see the Great Wall model with a fuel consumption of 5L per 100 kilometers.
Great Wall Lemon Hybrid DHT platform is a new energy platform of GREAT Wall Motor's PHEV architecture, with a pure electric mileage of up to 200km, which is a PHEV platform with a long pure electric mileage worldwide, and a highly integrated oil-electric hybrid system. It integrates 1.5L or 1.5T hybrid special engines, generators and drive dual motors, fixed shaft transmissions, etc., which can realize various working modes such as EV driving, hybrid drive, series drive energy recovery, idle shutdown and so on. The minimum fuel consumption can reach 4.6 liters of comprehensive fuel consumption per 100 kilometers. Harvard, which is currently equipped with this system, is about to be listed soon, and the core models of the Great Wall will be built based on this system in the future.
It is worth mentioning that the lemon hybrid DHT technology is completely independent design, completely independent research and development, and has completely independent property rights. Although many domestic brands have also launched PHEV models before, the release of lemon hybrid DHT technology has made Great Wall the first domestic brand to launch a dual-motor HEV architecture.
NO.3 Geely SEA vast platform
Geely SEA Platform is the first pure electric exclusive architecture developed by Geely Automobile, and the core feature is that it is highly original at the hardware layer, system layer and ecological layer, and is a full ecological architecture from hardware to chip to application. SEA Haohan intelligent evolution experience architecture, development took 4 years, R & D investment of more than 18 billion yuan.
Geely SEA Haohan platform has a strong self-iteration ability in the field of automatic driving, only cockpit and cloud, using the new three electric concepts of electric drive, electric management and electric ecology, and its power battery can achieve 200,000 kilometers of non-attenuation under NEDC conditions, cycle life of up to 2 million kilometers, maximum 800 volts of high-voltage system support, charging 5 minutes of endurance of 120 kilometers.
Matching the two-speed reducer developed by Geely's self-service, the maximum wheel end torque can reach 8000Nm, the acceleration time of zero to 100 kilometers is less than 3 seconds, the front and rear counterweights are 50:50, and it can be equipped with a high-performance electric four-wheel drive system, and the power distribution reaches the millisecond level.
The model sizes under the SEA Haohan architecture cover the A-E class (wheelbase 1800-3300mm), and at least 8 brands are currently covered, and more than 16 models are under development.
NO.4 Volkswagen MEB platform
The Volkswagen MEB platform is a new platform specially developed by Volkswagen in order to comply with the trend of electrification in the global automotive market. The MEB platform has a highly integrated electric drive system, which realizes the high integration of the motor, electronic control and reducer "three-in-one". While increasing the use of space, improve the response speed of the electronic control system, the use of four wheels and four corners layout, so that the MEB platform model has a larger wheelbase, shorter front and rear overhang, no central channel and other characteristics, with the appearance of A+ class cars, B class car space and other characteristics.
The ID4 model currently equipped with the MEB platform has been launched, and Volkswagen plans to sell 1 million electric vehicles per year by 2050.
The ID. series is not a "test" of Volkswagen's new energy models, and from the perspective of Volkswagen's dedication to the MEB platform, as a huge automotive industry giant, Volkswagen must hit it in one hit, and there is no room for more redemption.
However, in fact, the sales of ID series products are relatively slow, a single model has not yet sold more than 10,000 a month, it is indeed impossible to say, Volkswagen currently needs to put the MEB platform planned models into the market as soon as possible, to maximize the value of this platform.
Although we judge that the sales volume of the Volkswagen MEB platform throughout its life cycle is much lower than expected, and the MEB platform will withdraw from the stage of history in advance, it does not mean that Volkswagen will not iterate and optimize during this period.
