On the basis of the technology laid by the previous Shangri-La plan, Changan began to reconstruct the brand of new energy and intelligence.
On April 21, 2022, Changan's new pure electric brand "Deep Blue" held a media technology sharing meeting, released the world's first all-electric digital platform, the world's first high-frequency pulse heating technology, the first mass production of independent car range extender system and hydrogen fuel cell system, with two global firsts and two Chinese first mass production technologies, opening a new chapter in the future new energy market advancement.
The world's first all-electric digital platform
Deep Blue All-Electric Digital Platform is the world's first all-electric digital platform, which is based on pure electricity, while expanding hydrogen fuel cells, increased range and other forms of energy replenishment, is a full-track pure electric drive dedicated platform that takes into account future travel prospects and today's car experience, bringing users a variety of choices.
At the same time, based on Changan Automobile's more than 20 years of successful research and development experience in the field of new energy, the deep blue all-electric digital platform has the ultimate power system drive electrical efficiency, the high performance of the rear drive gene taking into account the four-wheel drive, the high intelligence based on the domain-controlled electronic and electrical architecture, and the high safety of the three-layer protection of the core car cloud.
The world's first micro-core high-frequency pulse heating technology
The Chang'an new generation of ultra-collector electric drive system of the deep blue all-electric digital platform has a maximum efficiency of up to 95% and has 163 patents, which can contribute to the low energy consumption of the whole vehicle and promote the development of the industry's electric drive to high power density.
At the same time, the world's first micro-core high-frequency pulse heating technology equipped with super collector electric drive, through the random frequency conversion IGBT opening and closing control, high frequency pulse and NVH balance algorithm, cell safety and life control, power system durability design and other innovative technology groups work together, can achieve a battery temperature rise of 4 °C / min in the -30 °C environment, low temperature power increase of more than 50%, low temperature charging time shortened by more than 15%, and comprehensively improve the winter difficulties of trams.
The first autonomous sedan range extender system/hydrogen fuel cell system to be mass-produced
Changan Deep Blue took the lead in mass-producing the autonomous car range extension system and the autonomous car hydrogen fuel cell system, which accelerated the popularization of the new energy vehicle market.
Among them, Changan Deep Blue's autonomous car range extension system is based on the coordinated design and control of the power system with extreme efficiency, the intelligent energy management control of real-time road conditions, and the high compression ratio depth Atkinson cycle and other technological innovations, which can achieve about 3.3 degrees of 1L oil power generation and sensorless operation in the whole region.
Changan Deep Blue's autonomous car hydrogen fuel cell technology adopts water-gas heterodial stack design, working condition mode intelligent perception algorithm, and a new generation of highly active platinum alloy catalyst gradient coating, which can achieve 1kg hydrogen power generation of 20.5 degrees, and achieve 3 minutes of ultra-fast energy replenishment.
Leading technologies empower new platforms
In addition to the above first new technologies, Changan Deep Blue All-Electric Digital Platform will also be equipped with many industry blockbuster technologies to lead the future new energy market with stronger comprehensive strength.
Among them, Changan's first domain controller Chang'an wisdom "core", high-computing cockpit domain controller, global speed OTA, platform design that meets the 2021 version of C-NCAP five-star security standards, iBC digital battery housekeeper, 5+1 information security and privacy protection and many other blockbuster technologies.
The first car of the deep blue all-electric digital platform is coming
As the first product of the new platform, the C385 can be described as the technology of Changan Deep Blue. The body size of the C385 is 4820*1890*1480mm, the wheelbase is 2900mm, and the wind resistance coefficient is as low as 0.23Cd, which is comparable to the Model 3 level and reaches the industry-leading level. The whole series is rear-wheel drive, equipped with a rear H-arm multi-link independent suspension system, highlighting the sporty characteristics of wide-body coupe.
In terms of features and configuration, the C385 is equipped with the largest 19-inch wheels in its class, a 14.6-inch sunflower screen that can be intelligently steered, and an electric hatchback door that allows convenience and premium to coexist.
In terms of core performance parameters, under CLTC conditions, the C385 pure electric version with endurance-based version has a comprehensive working range of more than 700 kilometers, the performance-based version has a maximum power of more than 190 kilowatts, and the power consumption is as low as 12.3 kWh/100 km or less; the range of the extended range full oil full power under the CLTC comprehensive working conditions can reach more than 1200 km, the cruising range of pure electrical comprehensive conditions can reach more than 200 km, and the fuel consumption is as low as 4.5 liters/100 km or less The working range of the hydrogen-electric version under the comprehensive CLTC standard can reach more than 700 kilometers, and the hydrogen consumption of feed is as low as 0.65 kg/100km or less, which can achieve 3 minutes of ultra-fast energy replenishment.
The highlights of the C385 are far more than that, and in the future, when it is launched, there will be 100 leading product points to surprise users.
