Today, Changan Automobile held a deep blue brand technology sharing activity. At the technology sharing meeting, Deng Chenghao, CEO of Chongqing Changan New Energy Automobile Technology Co., Ltd., shared the new pure electric drive dedicated platform EPA1 with completely independent intellectual property rights and forward design of Changan. In addition, Yang Dayong, chairman of Changan New Energy, also introduced the original intention and vision of Changan Automobile to launch the Changan Deep Blue brand at the sharing meeting.
Changan Deep Blue All-Electric Digital Platform is a special platform for electric drives in the form of multi-energy replenishment that has been honed over five years, with four high attributes: the electrical efficiency of the extreme power system drive; the high performance of the four-wheel drive in the future; 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.
High efficiency: Chang'an's new generation of super-collector electric drive system adopts eight-layer flat wire winding, rotor double V topology configuration, ultra-low resistance wire, adaptive control algorithm and low resistance topology optimization, which brings more than 95% of the maximum efficiency of the system to the electric drive system.
High performance: The EPA1 platform is a performance platform that takes into account dual motors and four-wheel drives with a rear-drive approach. The maximum output of a single motor is 190 kW (about 258 hp), equipped with the first car C385, and the measured acceleration of 100 kilometers per 100 seconds is 5.9 seconds. The EPA1 platform is the world's first all-electric platform compatible with pure electric, extended range and hydrogen fuel power configurations. The EPA1 platform is equipped with the latest generation of brake dual redundancy system, which allows users to choose between comfortable and sporty braking modes.
High intelligence: Support all node controller upgrades/ vehicle control domain software upgrade speed of all vehicles≤ 3min/ cockpit software dual partition, to avoid the failure of vehicle upgrades, resulting in vehicle suspension / commonly used and new experience. In terms of intelligent driving, it supports intelligent assisted driving from point A to point B under the navigation path of high-precision map, covering scenes including automatic lane change, up and down ramps, etc.; in terms of intelligent parking, in the structured parking lot, parking and remote driving according to the memory path can be realized, and automatic parking and remote driving based on high-precision maps can also be realized; it can truly solve the user parking pain points and realize the dual safety guarantee of convenient travel and intelligent driving.
High security: five horizontal and nine longitudinal surround body design / more than 45% of the ultra-high strength steel ratio / all-round battery security protection; 5+1 network security and privacy protection policy, that is, five layers of defense in depth strategy, plus a complete set of privacy protection strategy covering the car end, cloud, mobile end; 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 pressure exhaust / full-time temperature alarm.
After introducing the technical information of the EPA1 platform, Changan New Energy also introduced some parameters of Changan Deep Blue's first model, C385.
The body size of Changan Navy C385 is 4820*1890*1480mm, the wheelbase is 2900mm, the aspect ratio is 0.78, and the shaft length ratio is 0.6.
Under CLTC conditions, the C385 pure electric version with endurance-based has a comprehensive working range of more than 700 kilometers, and the performance-oriented version has a maximum power of more than 190 kilowatts and a power consumption as low as 12.3 kWh/100 km or less;
The mileage of the extended range version of full fuel and full power under CLTC comprehensive working conditions can reach more than 1200 km, the cruising range of pure electric comprehensive working conditions can reach more than 200 km, and the fuel consumption of feeder is as low as 4.5 liters/100 km or less;
Under the comprehensive CLTC standard of the hydrogen version, the mileage 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. This will be China's first mass-produced hydrogen fuel cell sedan.
