In addition, Xiaopeng G9 will be officially released in June this year, from the parameters and information that has been exposed, Xiaopeng G9 will also have a strong product force, and will launch a frontal "encounter" with the Weilai ES7 and the ideal L9 released at the same time, and as for what kind of achievements this car can achieve in the future, it will not be known until the vehicle is listed.
First, charge for 5 minutes, endurance 200 +km
Xiaopeng Automobile officially said that the Xiaopeng G9 is a reconstruction revolution of hardware architecture, software architecture and communication architecture.
The Xiaopeng G9 adopts a new intelligent electric platform, including X-EEA 3.0 electrical and electronic architecture, XPower 3.0 power system, high-performance chassis and higher-level intelligent cockpit system.
▲X-EEA 3.0 electrical and electronic architecture
Previously, the person in charge of the electronic and electrical architecture of Xiaopeng Automobile also introduced the X-EEA 3.0 electronic and electrical architecture platform to the car.
Overall, The overall electronic and electrical architecture platform of Xiaopeng Automobile has a very clear technical evolution route, in the initial 1.0 era, Xiaopeng Automobile adopted a distributed electronic and electrical architecture, starting from P7 into the 2.0 era, introducing functional domain controllers, and realizing vehicle-level OTA and 100 Megabit Ethernet communication.
At this stage, the electronic and electrical architecture of Xiaopeng Automobile has entered the 3.0 era, using a central supercomputing + regional control hardware architecture. The way of the central supercomputing platform replaces the previous decentralized platform, which can better exert computing power and make the vehicle smarter.
Another feature of this architecture is the use of zone control, which has the advantage of significantly reducing the wiring harness in the car, reducing the difficulty of vehicle routing, and making the system more efficient. In terms of software architecture, Xiaopeng Automobile adopts a vehicle-level hierarchical software architecture. Detach the underlying software and basic software of the vehicle from the application software related to intelligence, technology, and performance.

In this way, when developing new functions, only the top level of application software needs to be studied and iterated, shortening the research and development cycle and technical barriers, so that users can enjoy the rapid iteration of the car after purchasing the car.
In the communication architecture, in order to adapt to the commonly used and new characteristics of smart cars, Xiaopeng Automobile has realized a sensorless OTA, and users can also upgrade when driving, and the entire upgrade duration is controlled within 30 minutes.
In terms of power architecture, each power load on the Xiaopeng car can be controlled, and it is necessary to judge whether it needs to be opened according to different scenarios and needs, which can better control the power consumption of the vehicle.
In addition, the Xiaopeng G9 uses the Xiaopeng XPower 3.0 power system, which has five key features.
The first is the high voltage, all the components on the car are 800V class, can support 800V high voltage.
The second point is overcharge, Xiaopeng Automobile's maximum charging current can reach more than 600A, it is very difficult to do this, Xiaopeng Automobile has reduced the resistance of each link of the high-voltage connection, and it is also necessary to achieve special safety protection.

At the same time, Xiaopeng Automobile also adopted a 480kW charging pile, in order to achieve a large current, developed a liquid-cooled charging gun, not only to achieve a large charging current, but also to significantly reduce the weight of the gun, to achieve an excellent experience.
The third is high energy, only fast charging can not solve the user's vehicle experience, but also need to have a long endurance, which requires the vehicle must have high energy to meet the needs of users.
The fourth is efficiency, in order to achieve this goal, Xiaopeng Automobile uses silicon carbide to achieve the highest efficiency of the electric drive system, which can reach 95%.
The fifth is strong power, which is achieved through the combination of electric drive assembly and battery assembly. In terms of batteries, Xiaopeng Automobile adopts a cell with high energy density and supports overcharge, and develops an efficient thermal management system, including battery Pack thermal management and vehicle thermal management, which efficiently transmits battery heat generation to the outside of the car during the overcharge process.
Second, the full-scene L2 will not be absent, and the ground logo can be recognized
In addition to the new electronic and electrical architecture and power system, the all-scenario, point-to-point intelligent assisted driving of the Xiaopeng G9 will become another highlight of the Xiaopeng G9.
The Xiaopeng G9 will be equipped with Xiaopeng XPILOT4.0 hardware, equipped with two lidar and multiple 8-megapixel cameras and other perception hardware. In terms of computing platform, Xiaopeng G9 is equipped with two NVIDIA OrinX chips, and the single computing power can reach 254TOPS.
Thanks to the XPILOT4.0 hardware, Xiaopeng G9 will achieve all-scenario, end-to-end intelligent assisted driving.

According to the official description of Xiaopeng Automobile, Xiaopeng G9 does not need to identify the use environment, from the starting point to the end, from P gear release to re-insertion, the whole process can provide intelligent driving experience.

Of course, the "P" mentioned by Xiaopeng Motors in the article can also be interpreted as intelligent assisted driving from the parking lot to the parking lot.
Previously, Che Dongshi had also experienced the cross-floor memory parking function of Xiaopeng P5.
With the cross-floor memory parking function, after arriving at the basement, the whole process of parking can be handed over to the vehicle for operation, no longer need to go through the difficult identification of parking spaces process, no longer need to worry about the "twists and turns" of the ramp, practicality can be said to have a qualitative change.
In terms of urban L2, Xiaopeng Motors took the lead in showing a beta version of the urban NGP based on XPILOT3.5 hardware in November last year.

He Xiaopeng, chairman of Xiaopeng Motors, said that in the test area of Guangzhou's urban area, the P5 test vehicle equipped with the city's NGP has appeared many times that there is no need to take over tens of kilometers, or only once, which is very close to the effect of high-speed NGP. In terms of team, the R&D and data team of Xiaopeng Automobile's intelligent auxiliary driving has nearly 1500 people, and the scale is relatively large.
"Judging from the test results, the city-level NGP effect pushed out within this year will be better than the Tesla FSD effect." He Xiaopeng said.
In addition, in addition to Xiaopeng's urban NGP, Huawei, Weima, Zhiji, and Tesla are all testing their own urban navigation assisted driving functions, and all plan to be introduced to the market in 2022 or 2023.
In addition, Xiaopeng G9 can also render the driving environment in real time through dynamic calculation, 360-degree simulation display, as can be seen from the picture, Xiaopeng G9 can identify ice cream tubes, column barrels, speed bumps, indicator lines on the ground and other information.

Conclusion: Wei Xiaoli will "start again"
As the head players of the new domestic car-making forces, Weilai, Xiaopeng and Ideal will all launch their own new SUV models in 2022, and will all begin to be delivered at the end of 2022. Therefore, for these three companies, releasing their new SUV models at similar time points can be understood as an opportunity to start again.
With the liberalization of the domestic three-child policy, SUV models will become the just need for more families to buy cars and buy cars, so Weilai, Xiaopeng and Ideal who can win the competition for SUV models in 2022 are likely to take a leading position in the entire intelligent electric vehicle track.
