On May 20, BYD released the CTB battery-body integration technology and the first e-Platform 3.0 model equipped with CTB technology - Seal. The Seal opened for pre-sale on the same day, with a pre-sale price of RMB 21.28-28.98 million. BYD Corsair is the world's first production vehicle equipped with CTB technology and the first model equipped with iTAC technology, rear-wheel-drive/four-wheel drive architecture, and front double wishbone.
BYD CTB battery-body integration technology simplifies the body structure and production process. Thanks to the advantages of CTB technology, the e-Platform 3.0 with CTB technology achieves breakthroughs in safety, handling, efficiency, and aesthetics, giving the whole vehicle stronger performance.
Integrated design enhances the safety of the whole vehicle, creating a "crash-proof electric car"
CTB battery-body integration technology further merges the battery cover and 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 component. This integration simplifies the body structure and production process and is a disruptive change to the traditional body design.
The structure of the CTB blade battery pack is inspired by the honeycomb aluminum structure. The blade cells themselves are so secure that adjacent cells can be closely aligned together. Rows of blade cells form a structure like a honeycomb core, forming a honeycomb-like structure through the top cover and bottom plate. This allows the structural strength of the CTB blade battery pack to break through and be able to pass the extreme test of being crushed by a 50-ton heavy truck without any problems.
At the same time, CTB technology achieves a high degree of integration between the body and the battery system, doubling the torsional stiffness of the entire vehicle. The torsional stiffness of pure electric vehicles equipped with CTB technology can easily exceed 40,000N-m/°, comparable to a million luxury cars, making the upper limit of fuel cars the lower limit of electric cars.
CTB technology achieves the improvement of vehicle strength and stiffness, which in turn achieves the improvement of safety performance and can meet the "Super 5 stars" safety standard. CTB technologycano creates a "crash-proof electric car".
A natural "sportsman", a perfect balance of handling and comfort
Thanks to the safety and structural strength of the CTB blade battery pack, there is plenty of room for the model's performance indicators to shine. High torsional stiffness means less deformation in various operating conditions, the faster response of the vehicle body, and a significantly improved vehicle handling experience in corners.
At the same time, the CTB blade battery pack has a more balanced mass center to achieve a 50:50 golden axle load for the entire vehicle, which results in better vehicle stability, lower inertia, and faster body response. The e-Platform 3.0 model equipped with CTB technology can achieve a perfect "low" body sporting posture under the pure electric platform and is born to be a "sportsman".
As for the chassis, the high-performance suspension combination of front double-wishbone makes the platform 3.0 medium platform pure electric model, in the transverse, longitudinal, vertical three directions of vehicle performance significantly improved, better handling performance, better longitudinal anti-pitch ability, vertical suspension friction is lower, better comfort.
The first Corsair equipped with CTB technology comes out of the blue, which is cool to drive and highly efficient
As the first e-platform 3.0 model equipped with CTB technology, Corsair is a masterpiece of BYD in the field of advanced electric vehicle technology. Its elk test passes the speed of 83.5km/h, the single 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 has a low-slung shape and low wind resistance of 0.219. The larger arrangement space allows the Seal to adopt the four-drive architecture of the front asynchronous motor + rear synchronous motor. The four-wheel-drive version of the Corsair accelerates to 3.8 seconds, and the power is just fierce and swift.
At the same time, the energy consumption of Corsair 4WD is as low as 12.7kWh per 100km, taking into account the multiple considerations of performance and energy consumption. In addition, the Corsair is equipped with an active air intake grille AGS as standard, which improves the waste heat utilization efficiency of the low-temperature heat pump system by 20% and improves the range for every kilometer for users.
In terms of charging, the high-voltage electric drive boost charging solution of e-Platform 3.0 can enhance the charging power through the high-voltage platform, making full use of the upper limit of the national standard current, realizing a wide range of constant power charging, with a range of more than 300 km in 15 minutes of charging; and it is fully compatible with all current public charging piles, providing a more suitable fast charging solution for Chinese consumers nowadays.
The e-Platform 3.0, equipped with CTB technology, achieves breakthroughs in safety, handling, efficiency, and aesthetics, creating a product that consumers can "buy with eyes closed and drive to their heart's content". As a leader in new energy vehicles, BYD is committed to achieving safety without limiting consumers' driving pleasure. The Seal is BYD's practical exploration of the next generation of electric vehicles and its realization in the products.
