Red Network Moment News May 24 (Correspondent Li Yanhong) Recently, BYD released ctB battery body integration technology and the first e-platform 3.0 model equipped with CTB technology - SEAL. Seal opened pre-sale on the same day, and the pre-sale price was 212,800-289,800 yuan. BYD Seal is the world's first production car to be equipped with CTB technology, and it is also the first model to be equipped with iTAC technology, rear-drive/four-drive architecture, front double wishbones + rear five-link chassis suspension.
BYD's 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 vehicle stronger performance performance.
Integrated design improves vehicle safety and creates a "continuous electric vehicle"
CTB battery body integration technology further combines the battery cover and the body floor into one, evolving from the original battery pack "sandwich" structure to the "sandwich" structure of the whole vehicle. The power battery system is both an energy body and a structural part. This convergence simplifies the body structure and production process and is a disruptive change in traditional body design.
The structural inspiration for ctB blade battery packs is derived from the honeycomb aluminum structure. The blade battery itself is very safe, and adjacent cells can be tightly arranged together. Rows of blade batteries are composed of structures like honeycomb cores, and honeycomb-like structures are formed through the upper cover plate and the bottom plate. This allows the structural strength of the CTB blade battery pack to break through, and it can successfully pass the extreme test of 50-ton heavy truck crushing.
At the same time, CTB technology has achieved a high degree of integration between the body and the battery system, and the torsional stiffness of the whole vehicle has been doubled. Pure electric vehicle models equipped with CTB technology can easily exceed 40,000 N·m/° body torsional stiffness, comparable to million-level luxury cars, so that the upper limit of fuel vehicles becomes the lower limit of electric vehicles.
CTB technology has realized the improvement of the strength and stiffness of the whole vehicle, and then realized the improvement of safety performance, which can meet the safety standards of "super five stars". The e-platform 3.0 model equipped with CTB technology has increased the safety of the front-impact structure by 50% and the safety of the side-impact structure by 45%. CTB technology can create "electric vehicles that crash continuously".
A natural "athlete", the perfect balance of handling and comfort
Thanks to the safety and structural strength of the CTB blade battery pack, the performance indicators of the model can be played in the sky. The high torsional stiffness means that the shape variable of the vehicle is smaller, the body response is faster, and the vehicle cornering experience is significantly improved under various working conditions.
At the same time, the centroid of the CTB blade battery pack is more balanced, achieving a 50:50 gold axle load of the whole vehicle, which has better stability, lower inertia, and faster body response. The e-platform 3.0 model equipped with CTB technology can achieve a perfect "low lying" body movement posture under the pure electric platform, and is born as an "athlete".
In terms of chassis, the combination of high-performance suspension with front double wishbones + rear five linkages makes the e platform 3.0 medium-sized platform pure electric model significantly improve the performance of vehicles in the three directions of lateral, longitudinal and vertical directions, with better handling performance, better longitudinal anti-pitch ability, lower vertical suspension friction and better comfort.
The seals with the first CTB technology turned out to be cool and efficient
As the first e-platform 3.0 model equipped with CTB technology, SEAL is BYD's masterpiece in the field of advanced electric vehicle technology, and its elk test passed the speed of 83.5km/h, the single-shift line test passed the speed of 133km/h, and the maximum lateral stable acceleration of 1.05g, which has excellent performance.
Thanks to the technical advantages of CTB, the seal shape is low and the wind resistance is as low as 0.219. The larger layout space allows the SEAL to adopt a four-drive force architecture of front asynchronous motor + rear synchronous motor. The SEAL four-wheel drive version of Zero Hundred accelerates to 3.8 seconds, and the power is just rapid.
At the same time, the 100-kilometer energy consumption of the SEAL four-wheel drive version is as low as 12.7kWh, taking into account multiple considerations of performance and energy consumption. In addition, seals are equipped with active intake grille AGS as standard, which increases the waste heat utilization efficiency of the cryogenic heat pump system by 20%, and strives for excellence for every kilometer of user endurance.
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 upper limit of the national standard current, realize wide-range constant power charging, and the endurance of charging for 15 minutes can exceed 300 kilometers; and it is fully compatible with all current public charging piles, providing a more suitable fast charging solution for Chinese consumers at present.
E-platform 3.0 equipped with CTB technology has achieved new breakthroughs in safety, control, efficiency and aesthetics, creating products that allow consumers to "close their eyes and buy and open up". As a leader in new energy vehicles, BYD is committed to achieving safety based on the fact that consumers' driving pleasure is not limited. Seals are BYD's practical exploration of the next generation of electric vehicles and the realization of products.
