Since the popularity of the "acupuncture" test, various car brands have launched different forms of battery testing. In recent years, Changan's new energy brands, which have developed rapidly, have quickly become popular in the market with their excellent technology.
On December 1, Changan Qiyuan conducted all-round experiments on models such as the Golden Bell Jar battery and the Qiyuan Q05 equipped with digital intelligence AI electric drive at the Dianjiang Circuit, including family models to cope with various challenges on the track and complex road conditions, hydrothermal batteries, etc., to test their super strength in all aspects with excellent quality, especially the charm of digital intelligence AI electric drive.
Changan Qiyuan's two previously launched models sold quickly, and its worry-free range and leading technology brought by its super extended range power contributed to it. Among them, as a key component of the electric drive system, the AI electric drive provides the basis for the strong power performance of the vehicle. Changan Qiyuan's digital intelligent electric drive plug-in hybrid architecture includes P13 high-efficiency digital intelligent electric drive, 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. It has the three characteristics of high integration, high efficiency and high intelligence, which provides a solid foundation for the upward breakthrough of the model.
Changan Qiyuan Digital Intelligence AI electric drive is equipped with the world's first 10-layer hairpin flat wire oil-cooled motor technology, with an efficiency of up to 978%, which is at the leading level in the industry. Changan Qiyuan uses a quad-core TC387 chip with 300 trillion computing power per core as the main MCU chip, and its computing power is 50% higher than that of the two single-core chips of competing products, and the efficiency is more than 90% in areas with more than 90%. This system allows the maximum power of a single motor of Changan Qiyuan Q05 to reach 158kW, the peak torque is 330Nm, and the 000 acceleration enters the 7 seconds level.
The biggest concern of new energy vehicles is the cost of using the car, and users do not pay attention to whether their technology is extended range or plug-in hybrid. In this regard, Changan Yongyuan Digital Intelligence AI electric drive is miniaturized and lightweight, weighing only 110kg, which is 30kg lighter than competing products, and is truly the lightest in the world. The Qiyuan Q05 equipped with this system has a comprehensive maximum range of 1,215 km, and it is a short-distance pure electric travel and a long-distance hybrid mode. The industry's first electric drive constant temperature system realizes internal and external circulation through intelligent temperature control valves, so that the oil temperature is always in the 60 high-efficiency zone, and the 10-layer motor is always in the optimal performance range.
Qiyuan Q05 adopts the only independent global column combination bearing, which achieves a transmission efficiency of up to 984%, which is better than competing products. In addition, the world's original IEM intelligent driving management mode allows each product of the Changan Qiyuan family to have four scenario modes: long-distance, emergency, mountainous and parking charging. The A-ECMS intelligent energy consumption optimization algorithm is one generation ahead of the rules commonly used in the industry, inputting all parameters such as battery, engine, and transmission system into the PCU, and collecting more than 500 types of information such as drivers and vehicles at all times. In actual use scenarios, the Qiyuan Q05 can save energy by 6%, and the comprehensive fuel consumption of WLTC is as low as 133L, the fuel consumption is only 53L, which further reduces the cost of use for users.
In terms of battery safety, which users are most concerned about, Changan Qiyuan is equipped with Changan's self-developed "Golden Bell Jar" battery, which has the three advantages of hardware security, software security and standardized battery cells. The new high-standard thermal insulation material is used on the battery, and the thermal insulation performance is increased by 30% compared with the industry level, 100% thermal inhibition is realized, and the use temperature is increased by more than 200% compared with conventional materials. The battery also adopts more stable lithium iron phosphate and higher manufacturing standards to achieve all-round safety protection of the battery. In addition, through the real-time computing of cloud big data, the safety of the whole life cycle of the battery is guarded 7x24 hours a day, and 100% safety risks are prevented.
In this test, it also added a method that few car companies have been involved before, using Chongqing's iconic hot pot to cook batteries for a long time. Different from the splashing or blistering methods used by other brands, this test is to put the power battery into a hot pot at a high temperature and boil, and test the performance of the battery through continuous heating. Through such rigorous experiments, the high safety of the "Golden Bell Jar" has once again been demonstrated, bringing users a reassuring and reassuring experience.
