The rise of the electric drive model, the automobile market has formed a two-point world of fuel vehicles and new energy vehicles, although relatively pure electric vehicles are more economical and more comfortable, but the battery life anxiety has always been a product pain point that pure electric vehicles cannot solve in the short term. The brand of domestic new energy vehicles is more and more, and the manufacturers who are halfway out of the house are not in the minority, and the manufacturers and enterprises that have truly mastered the core three-electric technology are probably only BYD!
If you want to truly ban fuel vehicles, new energy vehicle companies still have a long way to go, on May 20, at BYD's new car pre-sale meeting, the CTB battery body integration technology was officially released, and this technology will be installed on the Ocean Network model SEAL, which is also the world's first CTB mass production car. The emergence of this core technology means that BYD has further breakthroughs in the field of new energy, and the seal long-endurance version can reach 700km, and 3.8S can break 100, which is equivalent to the death penalty for fuel vehicles! Pre-sale for more than 6 hours, sales have exceeded 20,000 units.
So what is the principle of this CTB technology, and what advantages will its emergence bring to electric vehicles?
CTB technology full name cell to Body, translated into Chinese is the battery body integration technology, as the name suggests is the "blade battery" deeply integrated into the vehicle structure, completely abandon the traditional hoisting hanging in the chassis mode, the battery pack system under this technology is both an energy body, but also a structural part, which is also one of the core technologies of BYD pure electric e platform 3.0.
So what benefits and advantages can the optimized design of this structure bring to pure electric vehicles?
First of all, the battery pack in the past was composed of a module of batteries, and then a battery pack composed of modules, and the actual space utilization was not high. Seal equipped with CTB technology is directly composed of a single cell body into a battery pack, which is conducive to improving the battery internal utilization space and energy density ratio, the same volume, the higher the battery energy density, the stronger the endurance, which is why the seal can easily achieve 700km true endurance.
At the same time, structural changes, the entire battery pack system not only plays a role in power transmission, it also incarnates into a structural part of the body as a whole, empowering the safety of the whole vehicle. Some people may wonder, the battery itself is a very fragile thing, how can it participate in withstanding the force? "A chopstick is easily broken, multiple chopsticks firmly hugged into a ball" The truth I believe everyone understands it, the combination of N battery cells forms a hard and incomparable battery pack as a whole, it can withstand the huge impact from the horizontal, longitudinal, vertical and vertical three dimensions of the huge impact, the official has done rigorous tests, high-strength battery packs in the 50 tons of heavy truck crushing, smokeless, no fire, and the battery cell can still be in a safe operating state, the pressured battery pack structure can still ensure normal and safe use after loading.
Secondly, equipped with CTB technology BYD seal, the torsional stiffness of the body is increased by 70%, which can reach 40500 N· m/° beyond the level of the Million Luxury car, as we all know, the torsional stiffness threshold of the general Million Luxury car is 40000 N · m /°, and the anti-elastic deformation ability of the seal has far exceeded this threshold, so under the pressure of external forces, the body structure of the whole vehicle can still maintain a better shape. The stronger the torsional stiffness, the more the SEAL can achieve small deformation in any working condition, the body responds quickly, and the chassis and lateral support performance are more stable, so under the extreme driving control, the body can always maintain a good posture with the driver's control commands. This is also why BYD Seals can achieve an elk test of 83.5km/h, a single-shift line test through a speed of 133km/h, a steady-state slewing maximum lateral stable acceleration of 1.05g, and various performance indicators that can reach a level comparable to the sports car level, a veritable "pure electric sports coupe".
Matched with the iTAC intelligent torque control technology, it can maintain the stability of the body through torque transfer, more than 50 milliseconds of wheel trajectory prediction, in advance to do a good job of pre-judgment correction, adjust the wheel end torque matching, to maintain the real-time stability of the body in the limit state. The independent suspension structure of the front double wishbone and the rear five linkages, combined with the stable body, can ensure the absolute comfort of the occupants in the car.
Finally, with the blessing of CTB technology, bydir seal chassis can achieve full flat design, coupled with the design of marine animal bionic aesthetics, the whole vehicle has achieved a low-lying and dynamic modeling posture, which looks like a lifelike seal creature from a distance. And this scientific design language not only looks dynamic and cool, the most critical thing is that the wind resistance coefficient of the whole vehicle can be reduced to 0.21, and the top aerodynamic application further reduces the body resistance and reduces energy consumption. Taking into account both performance and energy saving, BYD Seal is currently unique in the field of new energy.
Write at the end:
The most effective means of sentencing fuel vehicles to death and announcing their replacement status is definitely not to rely on "price reduction and sales", but to rely on the continuous innovation of new technologies, bydIR's CTB technology release, and further promote the new energy vehicle field technology to take a big step forward. BYD seal listing is not unreasonable, compared to those fancy technology configuration, BYD with core technology will go further!
