Recently, many media have launched various extreme range/power consumption tests, and Xpeng Motors' models have performed particularly well in battery life and energy consumption in a number of new energy vehicle tests. He Xiaopeng, chairman of Xpeng Motors, even said to Gu Jie, the head of the powertrain, on Weibo, that "what is more conservative than the propaganda of intelligent driving is the propaganda of your battery life." There are also many Pengyou on the Internet who have posted energy consumption data and said frankly that there is no need for special footwork, and the cost of 1 kilometer is 5 cents in high temperature weather.
So there was He Xiaopeng himself who personally ended up "challenging a kilometer for 5 cents!" He Xiaopeng optoelectronic test live broadcast".
In the end, the test results of Xpeng G6 performed very well, with a final range of 608.5km and a range of 90% with an average power consumption of 13.1kWh/100km with a charge of 85%, showing that the G6 with 0 endurance can run another 29km. You must know that this is the data measured according to the user's real car use scenarios, including high-speed, air conditioning and other working conditions.
Xpeng G6 nominal power consumption of 100 kilometers is 13.2kWh, and the average price of one kilowatt-hour of electricity is calculated from the home charging pile of 0.45 yuan, and the cost of running 100 kilometers is less than 5 yuan (only 4.75 yuan) after multiplying the two numbers, that is, Xpeng G6 only takes less than 5 cents to run a kilometer. By calculating the accounts and comparing the cost of oil cars and trams, it can be found that the cost of oil cars reaches 0.8 yuan for 1 kilometer, which is 20 times the cost of trams. Judging from the physical gap, the cost of Xiaopeng G6 is only more than 2000 yuan a year, compared with the cost of oil trucks of more than 8000 yuan, the gap is equivalent to an Apple 13Pro max.
Then again, what is the confidence of Xiaopeng Motors to dare to do a live broadcast to test the challenge of "5 cents per kilometer"? Naturally, it is a three-electric technology, such as the self-developed 800V XPower electric drive system, high-voltage SIC electronic control, and high-efficiency battery technology. Then let's see how powerful its three electric are.
The first point to emphasize is that Xpeng Motors' 800V SiC silicon carbide platform includes all high-voltage components such as power batteries, electric drives, power supplies, and compressors, which is what we call 800V for the whole vehicle, which is a very important factor to achieve "fast charging, low energy consumption, and long battery life". Let's focus on the three-electric technology.
High-voltage SiC electronic control: the key to strong power and long battery life
As we all know, motors, batteries, and electronic controls are the three most important components of new energy vehicles, which are what we call the three electrics. The strong power brought by the motor and the fast charging and long battery life brought by the battery are directly perceived by us as consumers, and we have discussed a lot. Relatively speaking, electronic control is not so intuitive, but its quality directly affects the performance of the motor and the battery life.
Electronic control (motor controller), to be responsible for controlling the operation of the motor, monitoring the operation status of the motor, reporting motor faults, rectification and inverter, etc., here to know one thing, that is, in the process of inverter and rectification will produce loss, so the efficiency and stability of the electronic control will directly affect the endurance of the vehicle and the operation of the motor.
SiC power devices are the core components of energy conversion and transmission in electronic control, which can work at higher voltages and temperatures than traditional IGBTs, and have lower on-resistance and faster switching speeds. It has clear advantages in terms of increased system efficiency, power density, and operating temperature.
What are the advantages of Xpeng's self-developed electronic control technology? For example, the use of trench power devices, advanced all-plastic packaging technology, direct cooling channel design, etc., will not be expanded, directly look at the results: the comprehensive working condition efficiency of more than 98.5%, the highest efficiency point of 99.6%, are the first echelon of the industry.
In addition to the hardware level, the management strategy at the software control level is also important to further improve the efficiency and performance of the electric drive system, just to give a simple example. Household air conditioners are familiar to everyone, there are level 1 energy consumption, level 2 energy consumption, level 3 energy consumption, and frequency conversion. The high-efficiency electric drive system is an air conditioner with level 1 energy consumption and inverter function, which is intelligent, easy to use and special power saving.
X-power electric drive: powerful and quiet
Compared with electronic control, the electric drive is more intuitive, and everyone may have seen it, and the size of the electric drive on different models is different. So what makes a good electric drive? High efficiency and light weight. It should be noted that the electric drive mentioned here is a combination of motors, electronic controls, reducers and other components.
Xpeng's X-power electric drive has an operating efficiency of 92% and a maximum system efficiency of 95.5% (the highest efficiency of the motor reaches 97.5%), reaching the level of the first echelon in the industry.
The second is high integration. This is easy to understand, the small electric drive system takes up the smallest space, and the most direct thing is that the trunk space can be made a little larger. In addition, smaller will also be relatively lighter, further reducing the weight of the vehicle, which is beneficial to battery life and handling. The X9 has an industry-leading power density of 2.7kW/kg.
The other is NVH performance, which directly affects the driving experience, after all, good quietness is an important sign in high-end electric vehicles. The official data is that the noise of this electric drive system is ≤76dB at a distance of 1m, which is also an industry-leading level.
NVH is not easy to do well, because it is a system optimization, such as the optimization of the gear design, materials, housing, and even the harmonics of the control motor, in order to finally achieve a good NVH performance.
High-efficiency battery: 5 minutes of charging, the range can be increased by up to 200km
Battery technology covers many aspects such as fast charging, battery life, safety and power performance, and here we mainly talk about fast charging and battery life.
The first is the charging speed, for the standard 3C battery version of the product, it can be charged in 5 minutes, the range will increase by 130 kilometers, and it only takes 20 minutes to charge 10%-80%.
In addition, as of July 2024, Xpeng will have 1,000 supercharging stations, 1,300 self-operated stations, and 1,000 self-operated supercharging stations. The all-new Xpeng S5 liquid-cooled ultra-fast charging station charges more than 10,000 kilometers in 1 second, and the starting speed of the gun is less than 13 seconds, effectively solving the user's charging anxiety.
It is worth mentioning that it has strong compatibility, in addition to the Xpeng supercharging system, it can also get faster charging speed (up to about 180kW charging power) at third-party charging piles. This is very critical, which means that Xpeng models also have a fast enough charging experience on third-party charging piles such as stars and oranges. In addition, the 4C battery can be charged in 5 minutes, and the range can be increased by up to 200km.
In terms of battery life, Xpeng's idea is not achieved through stacking batteries, but by reducing energy consumption with more efficient three electrics. For example, the 87.5kWh version of the battery of Xpeng G6 has a CLTC comprehensive range of up to 755km, and its real range achievement rate is good, which is a good experience of technology. You must know that in order for competitors to achieve this mileage, the battery capacity is 100 degrees.
In addition, a lot of effort has been put into thermal management, which simply means that whether it is a hot weather in summer or an extremely cold weather in winter, it can ensure good energy consumption performance, regardless of place or temperature.
Full-stack self-development is the core competitiveness
In the "cart" link at the end of the live broadcast, He Xiaopeng also connected with his old friend Li Bin, and talked about the past of insisting on self-developed cars when he encountered the problem of lack of cores and no suppliers. He also said that the reason why he has always insisted on independent research and development is to achieve independent development.
Indeed, full-stack self-developed technology is the core competitiveness. On the one hand, if the technology is in its own hands, it will not be stuck, and it can be constantly updated and iterated to maintain competitiveness. On the other hand, it has better cost control. It is understood that Xpeng is developing a next-generation electric drive system, which will further optimize the silicon carbide solution, reduce the amount of silicon carbide, and reduce the key cost by 50% while ensuring power efficiency, which can allow users to enjoy higher performance products at a better price. With its full-stack self-developed capabilities, Xpeng Motors will continue to maintain the strength of its leading three-electric technology in the future, and more fully unleash the potential of 800V high-voltage electric drive assemblies.
brief summary
In the live broadcast of this energy consumption test, the measured average power consumption of Xpeng G6 is only 13.1kWh/100km, which is indeed outstanding among models in the same class. It is worth mentioning that after the event, the official WeChat of Xiaopeng Motors solicited the owners of Xiaopeng G6 and Xiaopeng G9 to challenge the power consumption results of He Xiaopeng. As a result, many users have taken the initiative to post their average power consumption results under Weibo, and many of them are lower than the performance of the big brother, even as low as 11.1kWh/100km. This also fully reflects the strength of Xpeng Motors in the three-electric technology.
For users, they can enjoy longer battery life through affordable prices, and lower energy consumption also reduces the cost of daily charging.
