Changan Navy brand
Changan Automobile's layout in the new energy sector is not too late, as early as 2015, Changan released a new energy plan, but the actual situation is not satisfactory. Take The sales volume of New Energy Vehicles in Changan in 2021, although the annual sales volume exceeded 100,000 units, the proportion of a Model of Changan Ben E-Star exceeded 70%.
Changan Ben E-Star
In order to make Changan new energy vehicles develop better, Changan Automobile has released a high-end intelligent electric vehicle brand - Avita in addition to the release. At the "2022 Changan Automobile Global Partner Conference" held by Changan Automobile on April 13, it was officially announced that the Changan Deep Blue brand was established, which will take innovation and reconstruction, interconnection of all things, experience and low-carbon life as the brand pattern.
All-electric digital platform - EPA1 platform
At this deep blue technology sharing meeting, in addition to the new car C385, the most important thing is to build the EPA1 platform of the C385. The platform has four high attributes: the electrical efficiency driven by the extreme power system; the high performance of the four-wheel drive for the future 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 most critical thing is that this platform is not only a pure electric architecture platform, but also compatible with extended range power and hydrogen fuel power.
In terms of the three-electric system, the new car born on the EPA1 platform will adopt Changan's new generation of super-collector electric drive, which has eight-layer flat wire winding, rotor double-V topology configuration, ultra-low resistance wire, adaptive control algorithm, low resistance topology optimization and other technologies, so that the maximum efficiency of the entire electric drive system reaches 95%.
Although the extended range version of the power has not announced detailed power parameters, but from the published pictures and data, this set of power will adopt the layout of inline four cylinders, and will also use a high compression ratio, deep Atkinson cycle form, and 1L oil can produce about 3.3 kWh of electricity is still very interesting.
The hydrogen fuel version of the hydrogen reactor adopts the water-gas heterodial stack design, equipped with intelligent perception algorithm of working conditions mode and gradient coating of a new generation of highly active platinum alloy catalysts, and in terms of power generation efficiency, 1kg of hydrogen can generate about 20.5kWh of electricity, and can also achieve 3 minutes of ultra-fast energy replenishment. But the question is, can you find a hydrogen refueling station near your home?
In addition to power and high efficiency, in order to ensure the cruising range of pure electric vehicle models in winter, the EPA1 platform also has micro-core high-frequency pulse heating technology, which can reach 4 °C / min in the -30 °C environment, the low temperature power is increased by 50%, and the low temperature charging time is shortened by 15%, which greatly alleviates the experience of electric vehicles in extremely cold weather.
The EPA1 platform is a post-drive gene, taking into account the ultimate performance platform of four-wheel drive, the rear suspension of the model born of the platform will be equipped with H-arm multi-link independent suspension, which can effectively improve the rear suspension follow-up and high-speed stability.
In order to make the new car have better handling and power performance, the model born on the EPA1 platform also has a 50:50 front and rear axle-to-load ratio, and the maximum output power of a single motor can reach 190kW, the official said that the C385 measured 100 km acceleration of 5.9s, which also makes me look forward to the driving experience of the C385.
The EPA1 platform can also realize a global OTA, support all node controller upgrades/ car control domain software upgrade speeds of ≤ 3min/cockpit software dual partitions, avoiding the failure of vehicle upgrades, resulting in vehicle shutdown, and realizing a commonly used and new experience.
Secondly, the vehicle domain controller adopts the "Changan Smart Core" independently developed by Changan, which increases performance by 70%, reduces volume by 70%, and supports functions such as remote diagnosis.
The cockpit part, which also uses a high-power cockpit domain controller, can process the response speed and cockpit ecological expansion faster, using 8155 chips to achieve 105K DMIPS computing power.
In addition, in the assisted driving part, its intelligent driving domain controller can achieve up to L4 intelligent driving, support intelligent assisted driving based on point A to point B under the navigation path of high-precision map, and cover the scene including automatic lane change, up and down ramps, etc.
In terms of intelligent parking, in the structured parking lot, it is possible to park according to the memory path and remotely pick up, and it is also possible to realize automatic parking and remote driving based on high-precision maps.
Safety is paramount
In terms of safety, the EPA1 platform adopts a five-horizontal and nine-vertical surround body design, with a high-strength steel ratio of more than 45%, which meets the C-NCAP five-star safety standard and provides a full range of perimeter security protection for the battery.
In terms of battery temperature control management, the aerospace-grade full battery heat insulation technology, alcohol-cooled and efficient heat dissipation, transient pressure relief technology, overpressure sealing control, global anti-short circuit technology, directional pressure exhaust temperature and full-time temperature alarm and other technologies are adopted, even if there is an extreme cell thermal runaway, it can effectively avoid the whole package of thermal runaway.
Blockbuster new car C385 hit
In terms of appearance, the front design of the new car is a bit like the UNI-V model launched by Changan in recent times, and the closed front face outlines the X-type front through the lines on both sides, creating a stronger sense of sport.
The slender LED daily light group on both sides, its internal shape is somewhat similar to the logo of Chang'an, and the matrix light group with interactive lights is equipped below, which is very highly technological.
The side of the new car adopts a sneaky body shape, in order to further reduce the wind resistance, hidden door handles and low wind resistance wheels also appear on it, the overall style is more dynamic.
The rear of the body adopts a very exaggerated design, and the through-type taillights arrange the upper part of the rear, which is integrated with the tail wing of the tail box, taking into account the practicality and sense of science and technology at the same time, with a certain degree of recognition.
The interior of Changan Navy C385 adopts a different design style from all current Changan models, the instrument and central control screen adopt a stand-alone layout, the steering wheel adopts a double-frame design, and it is a sporty flat-bottom design. The central control screen adopts the 14.6-inch sunflower screen with intelligent steering with driving, which can be tilted left and right, and the sense of technology is full. Although there is no direct information to indicate that the car will use the Hongmeng system, from the layout of the interface, it is basically the same as the layout of the Avita 011 central control screen released earlier.
In terms of configuration, the new car will be equipped with AR-HUD head-up display system, Sony speakers, APA7.0 remote unmanned valet parking system, and electric drive high-frequency pulse heating technology. Among them, the APA7.0 remote unmanned valet parking system can create a "private driving" in the exclusive parking lot of "calling and going" for users.
The car will meet the premise of meeting the relevant national laws and regulations, the first unmanned independent queuing parking function outside the garage, the user can get off the car directly outside the garage, the system will queue up autonomously, drive the vehicle automatically through the barrier, automatically find a parking space, automatic parking, the whole process without user monitoring.
High-frequency pulse heating technology can solve the anxiety of tram use in winter, and can also achieve 5 minutes of heating 20 °C in the extremely cold environment of -30 °C, improve the low temperature driving performance of trams, and cooperate with waste heat recovery technology to improve the cruising range by 40-70km.
In terms of power, thanks to the expansion of the EPA1 full-power platform, C385 provides a variety of power systems, including a pure electric version of the comprehensive cruising range of more than 700km, the maximum power of more than 190kW, the power consumption under comprehensive working conditions of 12.3kWh/100km, the fastest acceleration time of 100 km 5.9s; the extended range version of the comprehensive endurance of more than 1200km, pure electric endurance of more than 200km, feed fuel consumption of 4.5L/100km or less The hydrogen fuel cell version has a comprehensive endurance of more than 700 km, the hydrogen consumption of feed is as low as 0.65kg/100 km, and the rapid replenishment of energy in 3 minutes.
