SEAL, the first e-platform 3.0 model equipped with CTB technology, opens for pre-sale

On May 20, BYD released the CTB battery-body integration technology and the first e-platform 3.0 model equipped with CTB technology, the Seal. The seals opened the pre-sale on the same day, and the pre-sale price was 212,800-289,800 yuan. BYD Seal is the world’s first mass-produced car equipped with CTB technology, and also the first model equipped with iTAC technology, rear-wheel drive/four-drive architecture, front double wishbone + 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, the e-platform 3.0 equipped with CTB technology has achieved new breakthroughs in safety, handling, efficiency and aesthetics, giving the vehicle a stronger performance.

The integrated design improves the safety of the whole vehicle and creates a “continuous collision electric vehicle”

The CTB battery body integration technology further integrates the battery upper cover and the body floor, from the original “sandwich” structure of the battery pack to the “sandwich” structure of the whole vehicle. The power battery system is both an energy body and a structural part. This fusion simplifies the body structure and production process, which is a subversive change to the traditional body design.

The structure of the CTB blade battery pack is inspired by the honeycomb aluminum structure. The blade battery itself is very safe, and adjacent cells can be arranged closely together. The structure composed of rows of blade cells is like a honeycomb core, and a honeycomb-like structure is formed by the upper cover plate and the bottom plate. This has made a breakthrough in the structural strength of the CTB blade battery pack and can successfully pass the extreme test of 50-ton heavy truck rolling.

At the same time, CTB technology achieves a high degree of integration between the body and the battery system, and the torsional stiffness of the vehicle is doubled. A pure electric vehicle equipped with CTB technology can easily exceed 40,000N m/° in torsional stiffness, which is comparable to a million-dollar luxury vehicle, making the upper limit of fuel vehicles the lower limit of electric vehicles.

The CTB technology has achieved the improvement of the strength and rigidity of the whole vehicle, and further improved the safety performance, which can meet the “super five-star” safety standard. For the e-platform 3.0 models equipped with CTB technology, the safety of the front impact structure is increased by 50%, and the safety of the side impact structure is increased by 45%. CTB technology can create “crash electric vehicles”.

A natural “athlete”, the perfect balance of control and comfort

Thanks to the safety and structural strength of the CTB blade battery pack, the performance indicators of the model can be exploited. The high torsional stiffness means that the vehicle has less deformation under various working conditions, the body responds faster, and the vehicle cornering experience is significantly improved.

At the same time, the center of mass of the CTB blade battery pack is more balanced, achieving a 50:50 golden axle load of the vehicle, better vehicle 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 under the pure electric platform, and is born a “sportsman”.

In terms of chassis, the high-performance suspension combination of the front double wishbone and the rear five-link makes the e-platform 3.0 medium-sized pure electric vehicle model significantly improve the vehicle performance in the horizontal, vertical and vertical directions, and the handling performance is better. Better anti-pitch capability, lower vertical suspension friction, and better comfort.

The first seal with CTB technology was born, driving 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. Its elk test passed the vehicle speed of 83.5km/h, the single-line shift test passed the vehicle speed of 133km/h, and the maximum lateral stable acceleration 1.05g, excellent performance.

Thanks to the technical advantages of CTB, the seal has a low profile and wind resistance as low as 0.219. The larger layout space allows SEAL to adopt a four-drive architecture of front asynchronous motor + rear synchronous motor. The zero-to-100 acceleration of the seal four-wheel drive version is as fast as 3.8 seconds, and the power is fierce and fast.

At the same time, the energy consumption per 100 kilometers of the seal four-wheel drive version is as low as 12.7kWh, taking into account the multiple considerations of performance and energy consumption. In addition, all SEAL series are equipped with active air intake grille AGS as standard, which improves the waste heat utilization efficiency of the low-temperature heat pump system by 20%, and strives for excellence in every kilometer of battery life for users.

In terms of charging, the high-voltage electric boost charging solution of the 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 kilometers after charging for 15 minutes; and it is fully compatible. All current public charging piles provide more suitable fast charging solutions for current Chinese consumers.

The e-platform 3.0 equipped with CTB technology has achieved new breakthroughs in safety, control, efficiency and aesthetics, creating products that allow consumers to “buy with their eyes closed, and open them as they please”. As a leader in new energy vehicles, BYD is committed to ensuring that consumers’ driving pleasure is not limited on the basis of safety. Seal is BYD’s practical exploration of the next generation of electric vehicles and its realization on products.
