On May 10, Beijing time, BYD officially released a new generation of e-platform 3.0 Evo and its first model, the Hiace 07EV. This mid-size urban intelligent electric SUV, known as the "all-round king", not only integrates BYD's latest technology cluster.
In addition to this car, BYD also released a motor yesterday, which is currently the world's highest speed mass production motor, with a speed of 23,000 rpm, with the blessing of the ultra-high speed drive motor, the Hiace 07 EV has a maximum speed of 225km/h, and the fastest 000 acceleration has reached 4.2 seconds, some people may think that this result is not amazing enough, but you can't take a sedan and SUV to compare 000 acceleration and top speed.
Interestingly, before that, Xiaomi Auto also released a motor, at the Xiaomi Automotive Technology Conference held in December last year, Xiaomi Super Motor V8s was officially released, claiming to reach the world's first speed of 27200rpm. Lei Jun said excitedly that this will be the world's motor speed ceiling and the world's top motor.
The motor has 578PS maximum horsepower, 425kW peak power, 635Nm peak torque, 98.11% maximum efficiency, and the motor power density can reach 10.14kW/kg. The motor is the industry's first 960MPa special silicon steel sheet, fully self-developed fixed rotor design, two-way full oil cooling and heat dissipation, S-shaped three-dimensional oil circuit design, 54-slot 6-pole design, 8-layer Hairpin flat wire winding, and 77% slot filling rate. Lei Jun revealed that Xiaomi's self-developed motor V8s is expected to be launched at the end of the year, and the specific model has not yet been announced.
That is to say, Xiaomi's V8S motor, for the time being, has not been mass-produced, and mass production is planned by the end of this year, in addition to this motor, the highest speed motor of Xiaomi car is currently mass-produced at 21000rpm, V6, V6s, the speed of up to 21000rpm, surpassing Tesla Model S paid, Porsche Taycan Turbo motor. Therefore, BYD clearly stated that it is the world's highest-speed mass-produced motor.
In addition, Yu Chengdong said when introducing the Zhijie S7 that the speed of this motor equipped with it can reach up to 25000 rpm, and 3000 rpm is reserved for safety. If Yu Chengdong has no moisture and unlocks this motor, it may be the current highest-speed mass production motor.
The most important thing is that I think BYD may not have realized that the motor speed is worth publicizing, because BYD is likely to feel that the high-speed rotation is more redundant performance, which cannot be played in most scenarios, just like the 800V architecture.
"Who said BYD doesn't have 800V?" Ling Heping, vice president of BYD Automotive Engineering Research Institute, once said to the media, "BYD not only has, but is also the first car company in the industry to launch a passenger car super 800V high-voltage platform." ”
Subsequently, Ling Heping threw out a PPT: "As early as 2015, BYD applied 800V technology to Tang DM and Qin EV, 4 years earlier than Porsche Taycan!" ”
But why BYD has never promoted this technology before, because BYD feels that the voltage of the charging pile cannot keep up at all, so BYD has no need to publicize it at all.
"Around 2015, it belongs to the embryonic stage of China's new energy vehicles, and the level of electric vehicles made by peers in the industry is far from being as high as it is now, basically 400V models. This makes the vast majority of charging piles in terms of charging infrastructure to adapt to 400V models. "At this time, BYD launched an 800V car, and the first problem we faced was that there was no 800V pile on the market."
So, BYD, a car company, is sometimes indeed more conservative in technical publicity, not as radical as the new forces in car manufacturing, but BYD's investment in technology research and development is definitely not worth doubting, R & D investment has always been the ceiling of domestic car companies, BYD's technology fish pond There are still many fish, but when these fish are fished out and how to publicize, you may need to plan well.
