[ Chexun Wang reported ] in ldquo; China heart rdquo; 2019 annual new energy vehicle power system selected activities, SAIC-GM Buick eMotion electric drive system with the performance, NVH (vibration reduction noise) and a number of the indicators show ldquo; a significant advantage rdquo; and leading-edge technology, highly professional judges affirmed, won ldquo; technology Leadership Award rdquo ;. At the same time, the system is equipped with electric light blue Buick MAV by outstanding performance in five major projects and the assessment of the actual vehicle testing, awarded ldquo; China heart rdquo; 2019 annual new energy ldquo; recommended models rdquo ;.
The award-winning Buick eMotion electric drive system developed in accordance with General Motors global safety standards, in order to balance the power output of both design and safety performance. The system uses a new high-efficiency, high power density, wide speed range of permanent magnet synchronous motor, the maximum power of 110 kilowatts, the maximum torque of 350 Nm, one hundred kilometers power consumption as low as 13.1 kwh, to deal with urban roads and more congestion, more than Kai stop the complex conditions more calm; equipped with new high-security, high reliability ternary lithium batteries, not only through the puncture, crush, soak, fire, overcharge, over discharge and short circuit seven heavy security detection limit of 13 categories , also increased the power between the core aerospace grade nano materials airgel, heat diffusion properties reach more than 10 times the national standard requirements; high-pressure system and driving key subsystems have reached more comprehensive than the functional safety of the highest level of system security ASIL D, clock with battery temperature monitoring and warning, dual independent high voltage discharge than 400 design requirements and system-level security measures to ensure high safety and high stability Buick eMotion electric drive system.
panelists recognized: ldquo; eMotion electric drive system assembly using lsquo; Four rsquo; integration scheme, performance, arrangement, by weight, had a significant advantage of the NVH. Five precise control of the vehicle controls to ensure functional safety, energy control, vehicle driving experience, charging efficiency and other aspects of performance. A ternary lithium battery cells, the battery pack between the cell interior and a composite material arranged by moduleMake sure the battery pack structure to meet higher test requirements. System at a high level within the industry. rdquo;
won ldquo; recommended models rdquo; Buick bluish 410KM version relies on General Motors superior resources and technical heritage in the new energy sector, according to the new energy vehicle characteristics and safety standards development forward, and with strict certification and testing of advanced ldquo SAIC-GM; wisdom made rdquo; system, laying a solid foundation for the vehicle’s high-security, high reliability and high durability. Buick bluish not only equipped with leading eMotion electric drive systems, electric drive systems also capture the ubiquitous electric drive noise, vibration and noise reduction technology with multi-level, multi-module design optimization strategies and Quiet-tuning Buick mute patent technology, comprehensive optimize road noise, wind noise performance, with exclusive tuned independent suspension system, bring quiet, comfortable, exquisite driving experience. In addition, innovative MAV SUVs designed to allow light blue Buick has a comfortable extension of passenger space and flexible flat load space, equipped with the new upgrade Buick eConnect 2.0 interconnect technology and a wealth of intelligent driver assistance technology, so users enjoy peace of mind of electric life.
As the domestic authority awards in the field of new energy vehicles, ldquo; China heart rdquo; new energy vehicle power system selection has been successfully held four times. Awards by the judges from the country’s top experts, including the organization get support China Automobile Industry Association, China Society of Automotive Engineers and other six industries, the award-winning powertrain represents the current mainstream of new energy vehicles in China the highest technical level.
