Nanfang.com (reporter / Zhang Shuang) on May 20, Byd Company Limited(002594) released CTB battery body integration technology and seal, the first e-platform 3.0 model equipped with CTB technology. The seal opened the pre-sale on the same day, and the pre-sale price was 2128289800 yuan Byd Company Limited(002594) seal is the world's first mass-produced vehicle equipped with CTB technology. It is also the first vehicle equipped with ITAC technology, rear drive / 4WD power structure, front double wishbone + rear five link chassis suspension.
Byd Company Limited(002594) ctb battery body integration technology simplifies the body structure and production process. Thanks to the advantages of CTB technology, e-platform 3.0 equipped with CTB technology has achieved new breakthroughs in safety, handling, efficiency and aesthetics, giving the whole vehicle stronger performance.
integrated design improves the safety of the whole vehicle and creates a "collision free electric vehicle"
CTB battery body integration technology further integrates the battery cover and the body floor, and evolves from the original battery pack "sandwich" structure to the "sandwich" structure of the whole vehicle. The power battery system is not only an energy body, but also a structural member. This integration simplifies the body structure and production process, and is a subversive change to the traditional body design.
The structural inspiration of CTB blade battery pack comes from honeycomb aluminum structure. The blade battery itself is very safe, and the adjacent cells can be closely arranged together. The structure composed of rows of blade cores is like honeycomb core, which is composed of honeycomb structure through upper cover sector and bottom sector. This has made a breakthrough in the structural strength of CTB blade battery pack and can successfully pass the extreme test of 50 ton heavy truck rolling.
At the same time, CTB technology realizes the high integration of body and battery system, and the torsional stiffness of the whole vehicle is doubled. For pure electric vehicles equipped with CTB technology, the torsional stiffness of the body can easily exceed 40000 n · M / °, which is comparable to millions of luxury vehicles, making the upper limit of fuel vehicles the lower limit of electric vehicles.
CTB technology improves the strength and stiffness of the whole vehicle, and then improves the safety performance, which can meet the safety standard of "super five stars". For e-platform 3.0 model equipped with CTB technology, the safety of front impact structure is increased by 50% and that of side impact structure is increased by 45%. CTB technology can create "electric vehicles with constant collision".
born "athlete", perfect combination of handling and comfort
Thanks to the safety and structural strength of CTB blade battery pack, the space for vehicle performance indicators can be vast. High torsional stiffness means that under various working conditions, the shape variable of the vehicle is smaller, the body response is faster, and the vehicle curve handling experience is significantly improved.
At the same time, the center of mass of CTB blade battery pack is more balanced to realize the 50:50 golden axle load of the whole vehicle. The vehicle has better stability, lower inertia and faster body response. The e-platform 3.0 model equipped with CTB technology can realize the perfect "low lying" body movement posture under the pure electric platform, and is naturally a "sports master".
In terms of chassis, the high-performance suspension combination of front double wishbone and rear five link makes the e-platform 3.0 medium-sized platform pure electric vehicle significantly improve the vehicle performance in the transverse, longitudinal and vertical directions, with better handling performance, better longitudinal anti pitching ability, lower vertical suspension friction and better comfort.
the first seal with CTB technology was born in the air, driving cool and efficient
As the first e-platform 3.0 model equipped with CTB technology, seal is a masterpiece of Byd Company Limited(002594) in the field of advanced technology of electric vehicles. Its elk test passes the speed of 83.5km/h, single line shift test passes the speed of 133km / h, and the maximum lateral stability acceleration is 1.05g, with excellent performance.
Thanks to the technical advantages of CTB, the seal is low lying and the wind resistance is as low as 0.219 The larger layout space allows the seal to adopt the four-wheel drive power architecture of front asynchronous motor + rear synchronous motor. The zero hundred acceleration of the seal 4WD version is as fast as 3.8 seconds, and the power is just fierce and fast.
Meanwhile, the 100 kilometer energy consumption of the seal 4WD version is as low as 12.7kwh, taking into account multiple considerations of performance and energy consumption. In addition, all seals are equipped with active air inlet grille AGS as standard, which improves the waste heat utilization efficiency of low-temperature heat pump system by 20%, and strives for perfection for users' endurance per kilometer.
In terms of charging, the high-voltage electric drive boost charging scheme of E platform 3.0 can increase the charging power through the high-voltage platform, make full use of the national standard current upper limit, realize wide-range constant power charging, and the battery life can exceed 300 km after charging for 15 minutes; It is fully compatible with all current public charging piles, providing a more suitable fast charging solution for Chinese consumers.
The e-platform 3.0 equipped with CTB technology has made new breakthroughs in safety, handling, efficiency and aesthetics, and created a product that allows consumers to "buy with their eyes closed and open freely". As the leader of new energy vehicles, Byd Company Limited(002594) is committed to making consumers' driving fun unrestricted on the basis of safety. Seal is the practical exploration and product realization of Byd Company Limited(002594) on the next generation of electric vehicles.
