In recent years, with the development advantages of new energy vehicles, China's own brands have soared in the high-end market, and almost every traditional mainstream car company has launched high-end new energy brands, with the word "expensive" as the main theme. The 200,000-class market, which was once afraid to touch, is now crowded with China brand cars, and there are even many hot-selling models of 300,000, 400,000 or even more than 600,000. But in fact, looking at the market, these so-called high-end models have almost no bright spots at the core technology level. They basically rely on stacking materials and selling futures to achieve higher prices.

But then again, in recent years, the technology research and development level of China automobile enterprises has also made great breakthroughs. Especially since 2023, many automobile companies have released very competitive innovative technologies, such as BYD's easy Sifang platform, Geely's "heaven and earth integration" version of Galaxy intelligent drive, and Ai 'an's quark electric drive. And these new technologies are expected to be delivered in mass production as soon as this year. Let's have a look.

Looking up to the easy Sifang technology platform: subverting the traditional driving system

As we all know, the off-road capability of traditional fuel vehicles mainly comes from the four-wheel drive system, and its underlying logic is basically the gear chain meshing control of parts such as transfer case and differential lock, so there will be inevitable performance loss and slow response time in power transmission or power feedback. Easy Sifang technology platform is the first mass-produced four-motor drive technology in China, which subverts the previous drive system of fuel vehicles.

The four wheel-side motors installed on the E-Sifang technology platform can realize pure four-wheel independent driving, and the power of the four wheels can be controlled independently and accurately. The maximum horsepower of the power system exceeds 1 100 horsepower, and the maximum speed is 20500 rpm. At the same time, all models of Sifang Science and Technology Platform will be equipped with 800V high-voltage SiC electronic control as standard, with the highest efficiency of 99.5%. When driving on desert slopes and icy roads, the Yisifang technology platform model can also have more stable adhesion, and the limit speed of ice and snow bypass is increased by 10% compared with the benchmark model.

Because the four wheel motors can be driven independently, the vehicle can realize the driving operation that traditional fuel vehicles can't, including the function of turning around in place. By controlling the reverse rotation of the left and right wheels, the turning radius of the vehicle can be greatly shortened.

Yi Sifang technology also has the ability to control ultra-high-speed tire puncture. After a single tire burst occurs at the maximum 120km/h, the system continuously adjusts the torque of four wheels at a very high frequency to maintain the grip of the remaining driving wheels of the vehicle, control the posture of the vehicle body and avoid losing control. In addition, the emergency floating function is also a highlight of the technology platform, and its core component protection ability reaches IP68 level, which can avoid the water fault when the vehicle core component floats in a short time, and it also has a certain driving force in water.

Generally speaking, the easy Sifang technology platform makes the vehicle have four legs as agile and strong as a cheetah, which improves the performance, safety and stability of the vehicle in various road conditions and brings a brand-new experience.

Geely's "integration of heaven and earth" version of Galaxy Wisdom Drive: Never get lost.

Following BYD's hope, Geely's brand-new Galaxy has also set off a lot of heat. It has three core technologies: Aegis battery, Raytheon hybrid 8848 and Galaxy N OS. Among them, Aegis battery mainly focuses on radiation safety and bottom-dragging collision protection; Raytheon HEX 8848 has evolved in thermal efficiency, performance and intelligent control, with a thermal efficiency of 44.26%. Galaxy N OS system is an interactive experience focusing on the whole scene, which can be said in milliseconds.

However, what is even more exciting is the upcoming "Heaven-Earth Integration" version of Galaxy Intelligent Driving Scheme, which is based on Geely satellite network and can realize L3-level driving assistance. It is estimated that in 2025, Geely will complete the networking of 72 LEO satellites. With the high-precision positioning module of centimeter-level satellite independently developed by Geely carried on the vehicle, Geely Yinhe Zhijia will have the ability of positioning without blind spots, which means that the vehicle will achieve global accurate positioning and never lose contact.

Moreover, the intelligent driving scheme also has a higher level of driving assistance. For example, when cruising at a high speed of 90km/h, it can stop in time in the face of static targets, which is much higher than the current industry-leading speed of 60 km/h. In the future, Geely Yinhe Zhijia will also realize cross-layer memory parking, high-speed emergency antelope obstacle avoidance, low-speed exploration crossing and other functions.

Ian Quark Electric Drive: Palm-sized V8 horsepower

Quark electric drive is a hot new electric drive technology just released by Ai 'an Automobile. According to Ai 'an, the quark electric drive brings super horsepower beyond the V8 engine with a palm-sized motor. Quark electric drive will be applied to Hyper-Haoplatinum series in the future, in which Hyper SSR with three motors accelerates 100 km 1.9s, and Hyper GT with single motor 4.9s behind it breaks 100. ..

Quark electric drive has the characteristics of "high power density and low heat loss". Smaller size and stronger power, the power density of the motor is increased to 12kw/kg, which is 100% higher than the industry 6kw/kg. It is higher than the EDU power system 10.8kW/kg built by Lucid, a new American power brand, for FE.

The core of quark electric drive is a series of technologies such as nanocrystalline-amorphous ultra-efficient motor, X-PIN flat wire winding, 900V high-efficiency silicon carbide, E-drive software, electronic gear shifting without power interruption and so on.

Among them, the "nanocrystalline-amorphous" alloy material is used as the motor core, which reduces the loss by 50%, improves the working efficiency of the motor to 97.5%, and reaches the highest efficiency of the motor to 98.5%. X-PIN flat wire stator technology and carbon fiber high-speed rotor technology can reduce the volume of quark electric drive by 25% and increase the power by more than 30%; The control module of SiC module has the advantages of high withstand voltage, high power density and high efficiency. The maximum full power working voltage is 900V, the peak power is greater than 320kW, and the maximum efficiency is over 99.8%.

It is understood that quark electric drive has three national patents of unique platform winding scheme, with power range of 70kW-320kW and torque range of 220-450 N m, which supports multi-platform compatibility and will be applied to exoskeleton robots, aerospace and other fields in the future.

Nowadays, the competition in the electrification market has entered a white-hot stage, and the advantages of core technologies will be amplified to an unprecedented height. Just like the era of traditional fuel vehicles, overseas brands such as Japan, Germany and the United States have a large number of technical patents, so they can expand in the global market. At present, the technical strength of China automobile brand is also in the leading position in the world on the new track of automobile electrification. It is believed that with the mass production of the above series of innovative technologies, the international influence of China brand will advance by leaps and bounds.
