01 Changan Deep Blue Brand
Changan Automobile's layout in the new energy sector is not too late. As early as 2015, Changan released the new energy plan , but the actual situation is not satisfactory. Take Changan's new energy vehicle sales in 2021. Although the annual sales exceeded 100,000 vehicles, the proportion of Changan Benben E-Star is more than 70%.
Changan Benben E-Star
In order to make Changan new energy vehicles better develop, Changan Automobile has released the high-end smart electric vehicle brand - Avita . At the "2022 Changan Automobile Global Partner Conference" held by Changan Automobile on April 13, the Changan Deep Blue brand was officially announced. The brand will use innovative reconstruction, interconnection of everything, free experience and low-carbon life as its brand pattern.
In product planning, Changan Deep Blue brand will launch a total of 5 new products this year, including C385, C673EV, UNI-K PHEV, UNI-V PHEV, and Auchan Z6 PHEV. The first domestic mass-produced hydrogen fuel cell sedan will also be unveiled (that is, the hydrogen-powered version of C385).
02 All-electric digital platform - EPA1 platform
At this Deep Blue Technology Sharing Conference, in addition to the new car C385, the most important thing is to build the EPA1 platform of C385. The platform has four high attributes: the electrical efficiency driven by the ultimate power system; the rear drive is a gene, taking into account the high performance of the four-wheel drive; the high intelligence based on the domain-controlled electronic and electrical architecture; and the high security of the three-layer protection of the core car cloud. The most important 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 three-electric systems, the new car born in the EPA1 platform will adopt Changan's new generation super collector driver, which has eight-layer flat wire winding , rotor dual 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 detailed power parameters of the
extended-range version power have not been announced, judging from the published pictures and information, this set of power will adopt the layout of inline four-cylinder , and will also adopt the form of high compression ratio, depth Atkinson cycle , and 1L of oil can generate about 3.3kWh of power. The hydrogen reactor of
hydrogen fuel version adopts a water-gas different side stack design, equipped with a working condition mode intelligent sensing algorithm and a new generation of highly active platinum alloy catalyst gradient coating. In terms of power generation efficiency, 1kg hydrogen can generate about 20.5kWh of electricity, and can also achieve super fast energy replenishment in 3 minutes. But the question is, can you find hydrogen refueling station near your home?
In addition to high power efficiency, in order to ensure the range of pure electric models in winter, the EPA1 platform also has micro-core high-frequency pulse heating technology. In an environment of -30℃, the battery temperature rise can reach 4℃/minute, the low-temperature power is increased by 50%, and the low-temperature charging time is shortened by 15%, greatly alleviating the electric vehicle experience in extremely cold weather.
EPA1 platform is a ultimate performance platform with rear drive as a gene and taking into account four-wheel drive. The rear suspension of the model born on this platform will be equipped with H-arm multi-link independent suspension, which can effectively improve rear suspension following and high-speed stability.
In order to give the new car better handling and power performance, the model born on the EPA1 platform also has a front and rear axle load ratio of 50:50, and the maximum output power of a single motor can reach 190kW. The official said that the C385 actually measured acceleration of 5.9s per 100 kilometers, which also makes me look forward to the driving experience of the C385.
EPA1 platform can also realize full-domain OTA, supporting all node controller upgrades in the vehicle/car control domain software upgrade speed ≤3min/cockpit software dual partitions, avoiding the vehicle shutdown due to failure in the upgrade of the vehicle and achieving a common and fresh experience.
Secondly, the vehicle domain controller adopts the "Chang'an Smart Core" independently developed by Changan, with 70% performance improvement, 70% volume reduction, and supports remote diagnosis and other functions. The
cockpit part also uses a high computing power cockpit domain controller, which can handle the response speed and cockpit ecological expansion faster. It uses the 155 chip to achieve 105K DMIPS computing power.
In addition, in the assisted driving part, its intelligent driving domain controller can achieve up to L4 level intelligent driving, and supports intelligent assisted driving from point A to point B under the high-precision map navigation path, covering scenarios including automatic lane change, up and down ramps, etc.
In terms of smart parking, in structured parking lots, parking according to memory paths and remote driving can also be realized, and automatic parking and remote driving based on high-precision maps can be realized.
03 Safety is the top priority
In terms of safety, the EPA1 platform adopts a five-horizontal nine-long-vertical encirclement body design, with a proportion of more than 45% of high-strength steel, meeting the C-NCAP five-star safety standard and providing all-round peripheral safety protection for the battery.
In terms of battery temperature control management, it adopts aerospace-grade full-battery thermal insulation technology, alcohol-cooled and efficient heat dissipation, transient pressure relief technology, overpressure sealing control, full-domain short-circuit technology, directional pressure sensing and temperate full-time temperature sensing alarm and other technologies. Even if there is extreme thermal runaway in the battery cell, it can effectively avoid the whole package of thermal runaway.
04 The heavyweight new car C385 is coming
Changan Deep Blue C385 built on the new EPA1 platform, officially positioned as an intermediate coupe. It not only has a wheelbase of 2900mm, but also provides three powers: pure electric, extended range, and hydrogen fuel cell, meeting the needs of different consumers.
In terms of appearance, the front design of the new car is a bit like the UNI-V model launched by Changan recently. The closed front face outlines the X-shaped front through the lines on both sides to create a stronger sense of sportiness.
The slender LED daytime running light groups on both sides have a slightly similar shape to the Changan logo. The matrix light group with interactive lights is equipped below, which is very technological.
The side of the new car adopts a sloping back body shape. In order to further reduce wind resistance, hidden door handles and low-resistance rims also appear on it, making the overall style more dynamic.
The rear of the body adopts a very exaggerated design, and the through-type taillights are arranged on the upper part of the rear, which is integrated with the tail wing formed by the trunk. It takes into account practicality and technology, and has a certain degree of recognition.
Changan Deep Blue C385 adopts a different design style from all models in Changan. The instrument and central control screen adopt an independent layout, the steering wheel adopts a double-spoke design, and a sporty flat-bottom design. The central control screen adopts a 14.6-inch sunflower screen that follows the driving intelligent steering, which can be tilted left and right, making it full of technology. Although there is no direct information that the car opportunity uses the Hongmeng system, from the perspective of the interface layout, it is basically the same as the layout of the central control screen of Avita 011 released previously. In terms of configuration of
, the new car will be equipped with AR-HUD head-up display system, Sony speakers, APA7.0 remote unmanned valet parking system, electric drive high-frequency pulse heating technology and other technologies.Among them, the APA7.0 remote unmanned valet parking system can create an exclusive parking lot "private driver" for users that "call it and go away".
This car will first launch the unmanned autonomous queuing and parking function outside the garage under the premise of meeting relevant national regulations. Users can get off the car directly outside the garage, and the system will queue up independently. The driving vehicle will automatically pass through the gate , automatically find parking spaces, and automatically park, without user monitoring throughout the process.
high-frequency pulse heating technology can solve the anxiety of trams in winter. It can also heat 20℃ in extremely cold environments of -30℃ to improve the low-temperature driving performance of trams. Combined with waste heat recovery technology, it can increase the range of 40-70km. In terms of power, thanks to the expansion of the EPA1 full power platform, C385 provides a variety of power systems, among which the pure electric version has a comprehensive range of more than 700km, a maximum power of more than 190kW, and a power consumption below 12.3kWh/100km under comprehensive operating conditions, with a fastest acceleration time of 100km per 100km; the extended range version has a comprehensive range of more than 1200km, a pure electric range of more than 200km, and a fuel consumption below 4.5L/100km; the hydrogen fuel cell version has a comprehensive range of more than 700km, a hydrogen consumption as low as 0.65kg/100km, and a quick energy replenishment in 3 minutes.
You may be curious to see this, C385 does not have a car logo? Currently, C385 is just the code name of the model. There will be an official launch conference for the model in May. At that time, the official name and the logo of the Deep Blue brand will be announced. It is expected to be officially launched in July and will be delivered in the third quarter. The next step is to release a new car in half a year, which is worth looking forward to.
05 Summary
This Changan Deep Blue Technology Sharing Session, a little regrettable, does not bring us more information about C385, but judging from the current information, its fashionable and personalized appearance, central control screen that can tilt left and right, and a variety of powers of pure electric/range extension/hydrogen fuel are enough to attract the attention of many consumers. The main competitors of the new car will be Xiaopeng P7, pure electric new cars such as BYD Seal and Zero Race C01, which will be launched, and of course, there are Tesla Model 3. Do you think this Changan C385 can fight them? Tell me in the comment section.
