On April 16, The Changan Deep Blue Technology Exchange Meeting was successfully held.
What is Chang'an Navy?
Changan Deep Blue is not only a car company, it is also an important achievement of Changan Automobile's intelligent and new energy strategy, and it is also a beautiful commitment to consumers who pursue quality experience and attach importance to scientific and technological life.
The value brought by Changan Deep Blue to consumers is multi-dimensional and diversified.
In Changan Deep Blue's Shangri-La plan, the development of EPA1, an exclusive platform for pure electric drives, is the top priority. At this exchange meeting, Changan Deep Blue officially interpreted the EPA1 platform of Changan Deep Blue to everyone.
After five years of research and development, the EPA1 platform has finally achieved success under the development of the R&D team, and the EPA1 platform will be compatible with a variety of power types, supporting pure electric, extended range and hydrogen electric models. The first model, the Changan C385 based on this platform, will also be officially mass-produced.
The C385 will launch three models with different powers, namely the pure electric version, the extended range version and the hydrogen version.
Among the three versions of the model, the most attractive to consumers is the hydrogen electric version of the model, hydrogen energy will be more environmentally friendly than the pure electric model, and the hydrogen consumption of the hydrogen version of the model is as low as 0.65 kg / 100km or less, and can also achieve 3 minutes of super fast energy replenishment.
As the first model of Changan Deep Blue, the C385 has attracted the attention of many netizens since its exposure. Its biggest highlight is the size, the C385 body length, width and height are 4820/1890/1480mm, and the wheelbase is 2900mm. And the wind resistance coefficient is as low as 0.23Cd. At the same time, the C385 also uses rear-wheel drive, which greatly satisfies the driving desire of the owner. From the data alone, the C385 is in a far leading position in both body length and wind resistance coefficient.
What is the EPA1 platform?
C385 is based on the EPA1 platform to create a product, the platform is a full track pure electric drive dedicated platform that takes into account the future travel prospects and today's car experience, with four high attributes of high efficiency, high performance, high intelligence and high safety.
Let's first look at the first of the four high attributes of EPA1 - high efficiency.
The EPA1 platform adopts Changan's new generation of super-collector electric drive system. In this system, Changan Deep Blue innovated and adopted five core technologies of eight-layer flat wire winding, rotor double V topology configuration, ultra-low resistance wire, adaptive control algorithm, and low resistance topology optimization, which increased the efficiency of the electric drive system by 0.9, 0.4, 0.1, 1.2 and 1.3 percentage points respectively, and finally brought more than 95% of the maximum efficiency of the system to the new generation of super collector electric drive of Chang'an.
The second highest of the four high attributes of EPA1 - high performance
The EPA1 platform is the world's first all-electric platform compatible with pure electricity, extended range, hydrogen fuel and other power configurations. Coupled with the new generation of brake dual redundancy system and H-arm multi-link independent suspension system, users can enjoy the joy of driving and driving while having safer braking protection.
The third highest of the four high attributes of EPA1 - high intelligence
The EPA1 platform is based on three domain-controlled electronic and electrical architectures, which supports global-speed OTA, which can realize OTA upgrades for all node controllers in the vehicle. At the same time, the EPA1 platform is also equipped with an intelligent driving domain controller, which can enable vehicles to achieve up to L4 level intelligent driving. L4 level intelligent driving will also make users more relaxed in driving, with L4 level intelligent driving will also allow users to be afraid of various emergencies, the computer will automatically judge the driving safety.
The fourth highest of the four high attributes of EPA1 - high security
In terms of platform safety, Changan Deep Blue adopts a wrap-around body design, which improves body safety, and C385 also provides a full range of peripheral safety protection for the battery, which can effectively avoid battery thermal runaway. In terms of information security, Changan Deep Blue has also adopted a 5+1 network security and privacy protection strategy to build a security barrier for user information. The application of the EPA1 platform to the C385 will also make itself better.
Changan Deep Blue is not only a car company brand, it goes beyond the scope of traditional car brands and creates a new electric vehicle ecosystem. And these are just the beginning, deep blue symbolizes exploration, life, technology and the future, Changan deep blue will do its best, let users and Changan deep blue together, first reach the future!
