In the current automobile market, new energy vehicles have become a trend and choice. However, many new energy vehicles have problems such as insufficient mileage, inconvenient charging, weak power, and battery **, so that users have to face many troubles while enjoying energy conservation and environmental protection.
In order to solve the problem of new energy vehicles, Changan Qiyuan has brought digital intelligence AI electric drives. In order to verify the hard power of digital intelligence AI electric drive, the Changan Qiyuan Challenge - Digital Intelligence AI Electric Drive Station was officially opened in Chongqing recently, showing the strength of digital intelligence AI electric drive and Changan Qiyuan product family in an all-round way through a number of interesting and challenging links such as Jinchana, 000 acceleration, high-ring high-speed experience and boiled battery.
Long battery life is worry-free.
Range anxiety has always been a pain point for new energy vehicles, although many cars claim to have a range of 700km, but the actual range will be discounted, and the speed of charging and replenishing energy is still not comparable to refueling. Therefore, since the birth of new energy vehicles, battery life has always been the biggest trouble for new energy vehicle owners.
Changan Qiyuan Digital Intelligence AI electric drive can bring users a super economical and super long battery life experience. The vehicle can achieve a combined fuel consumption (WLTC) of only 0 per 100 kilometers98 liters, the cost of electricity per kilometer is less than 01 yuan, the pure electric real cruising range (CLTC) reached 145km, and the real comprehensive cruising range (CLTC) reached 1300km. Whether it is urban commuting or long-distance travel, drivers can enjoy ultra-fuel-efficient and ultra-power-saving economy, completely breaking through the product pain points of traditional new energy vehicle range anxiety.
The ultimate ultra-economical also means more efficient and more powerful power output. The peak power of the digital intelligent drive motor is as high as 158kW and the peak torque is 330Nm。In hybrid mode, the long-range version of the model accelerates from 0 to 100 kilometers and only needs 68 seconds. Such performance strength makes Changan Qiyuan's models have good performance in the Gymkhana, zero hundred acceleration, and high-ring high-speed experience projects, with strong power and light acceleration.
Behind the "super provincial economy", it is inseparable from the technologically advanced power system. In the 2023 "China Heart" Top 10 Engines and Hybrid Systems Selection Activity, the Digital Intelligence AI Electric Drive has won good results with the advantages of high integration, high efficiency, and high intelligence characteristics, and has made the list. This is the 7th consecutive year that Blue Whale Power has won the list, and it is due to the application of many hard-core technologies.
Digital intelligence AI electric drive independently debuted 10-layer hairpin flat wire motor technology, with a motor efficiency of up to 978%。At the same time, the innovative dual-motor coaxial serial layout of the ultra-compact design reduces the volume by 26% and the weight by 30-40kg compared with competing products, further reducing the energy consumption of the whole vehicle.
The digital intelligence AI electric drive is a plug-in hybrid system composed of a high-efficiency dual-motor electric hybrid system and a special engine for the Blue Whale hybrid, which combines the engine with two high-performance motors to achieve two modes of gasoline-electric complementarity and pure electric drive. In addition, the digital intelligent AI electric drive also has advanced intelligent energy management capabilities. It can automatically find the optimal comprehensive energy consumption plan, automatically turn on the battery insulation in extremely cold environments, accurately control the oil temperature of the transmission, and utilize the waste heat of the engine.
In addition to the traditional EV and HEV drive modes, the vehicle is also innovatively equipped with the IEM intelligent driving management mode, which can automatically adjust the power output power according to the road terrain, intelligently adjust the taxiing** intensity, and adjust the intelligent power consumption and gasoline-electric complementary strategies in real time according to the navigation road conditions, creating a smoother driving experience and maximizing fuel and power saving.
Take the Changan Qiyuan A05 unveiled at the challenge as an example, its pure electric range reaches 145km, and the comprehensive range reaches 1300km, which greatly alleviates users' battery life concerns. At the same time, the fastest charging speed of Changan Qiyuan models is 7 minutes, with a range of 400 kilometers.
Security is key.
It can be seen from the month-on-month sales growth that new energy vehicles have been gradually accepted by consumers. However, with the continuous increase in the number of new energy vehicles, battery safety has become more and more concerned by consumers, after all, the battery is the core component of new energy vehicles, and its quality is directly related to the performance and reliability of the vehicle.
Regarding the unsafe scenarios of batteries, mainly wading, spontaneous combustion, short circuit, etc., these situations have caused a lot of trouble to new energy vehicle users. In order to solve the battery safety problem, Changan Qiyuan is equipped with Chang'an's self-developed golden bell cover battery, which has three significant advantages: hardware safety, software safety and standardized battery cells.
In terms of materials, the power battery uses new thermal insulation materials of military standards, using LFP cells and cylindrical cells, of which the thermal stability of LFP cells is 20% higher than that of ternary cells used in the mainstream industry. In addition, in terms of technology, the battery pack of Changan Jinzhongwei battery protects the safety of the whole life cycle of the battery in an all-round way through technologies such as aerospace-grade battery heat insulation, transient pressure relief, overpressure sealing, global anti-short circuit, directional pressure sensing and temperature discharge, and full-time temperature sensing alarm.
Jinbell Jar battery also realizes vehicle-cloud integration development, using voltage sequencing method, machine self-learning Xi, AI diagnosis and other dozens of early warning algorithm models, combined with the advantages of on-board BMS and cloud BMS, to solve the problems of low accuracy of battery thermal runaway safety hazard early warning and untimely disposal reminder of high-risk vehicles, realize all-round safety monitoring of the battery, warn the battery thermal runaway risk 12h in advance, and the accuracy is greater than 95%. Finally, the whole process of "Golden Bell Jar" battery from design, verification, production, transportation, use to the first is standardized, so that no link will cause potential safety hazards.
The ultimate safety performance of the bell jar battery is inseparable from Changan Automobile's long-term accumulation in new energy vehicle technology. At present, Changan Automobile has built a mature and complete R&D management, capacity management, and marketing management system, mastered more than 180 core new energy technologies, applied for a total of 580 patents, and also launched seven-in-one super-set electric drive, seven-in-one intelligent vehicle domain controller, a new generation of battery integration, new high-efficiency thermal management and other hard-core technologies, the R&D and manufacturing experience of these technologies have laid a solid technical foundation for Changan Automobile's self-developed Changan Golden Bell Jar battery.
The people evaluate the car. Digital AI electric drive is an important achievement of Changan Automobile in the field of new energy technology, and has achieved many technological breakthroughs. Including high-efficiency Blue Whale hybrid engine, high-efficiency and safe battery, AC and DC charging system, and advanced intelligent control integrating vehicle-end, cloud, and user-end data applications, etc., to bring more consumers a new energy product experience full of smart technology. Chang'an Qiyuan A05, which participated in the challenge this time, is an example, which is energy-saving and economical, hard-core power, intelligent and comfortable, and can meet the expectations of users for digital smart family cars.
