Learn about BYD’s CTB battery body integration technology in simple terms

The development speed of new energy vehicles has exceeded most people's psychological expectations. In 2022, BYD's cumulative sales were 1.8685 million vehicles, a year-on-year increase of 152.46% and a year-on-year increase of 212.82%. BYD also successfully surpassed Tesla and became the global new energy vehicle sales champion. Behind the rise of BYD is the result of adapting to the development of the times, and also the persistence of technology for ten years. In the silence of the past, BYD developed the e-platform into the 3.0 era. Models based on e-platform 3.0 have achieved the highest degree of integration of new energy vehicles, from architecture to modules, from hardware to software. Based on e-platform 3.0, there is almost no doubt that BYD will move towards the next glory.

In front of mass consumers, talking about technology often seems pale and feeble, and few consumers are willing to take the initiative to deeply understand the core technical details behind car companies. Smart consumers only look at sales volume, fuel consumption and the vehicle’s true performance. Currently, three products based on ePlatform 3.0 have been launched, and all have achieved excellent market performance. Supporting e-platform 3.0, 2.3.2. CTB battery body integration technology is considered the core of the core.

How high is the Wagyu X ingredient at the core of CTB technology?

What is CTB technology? CTB: Cell to Body, battery body integration.

In terms of technical details, CTB technology takes "battery body integration" as the core design concept and achieves a high torsional stiffness of 40,000+N·m/°. The body torsional stiffness is large and the control is significantly improved; at the same time, it participates as part of the body Force transmission and energy absorption improve the safety performance of the entire vehicle, which is also attributed to the increase in rigidity. If past technology used vehicle rigidity to protect the battery, then BYD's CTB technology uses the battery as part of the body's rigidity, allowing the battery to further strengthen the body and improve safety. It is a groundbreaking technology that allows the "battery baby" to transform into an integral part of the car body and no longer needs to be protected, but participates in protecting the members of the frame.

Do other domestic manufacturers have CTB technology?

At present, most domestic new energy vehicles still use CTP technology. The full name is Cell To Pack, which reduces or removes the battery module and directly integrates the battery cells and battery shells into the body chassis. We can understand it as battery sandwich technology, while CTB goes one step further and makes the entire vehicle including batteries. Sandwich, the degree of integration is further improved, making the battery no longer a "baby".

What forms the strength of CTB technology?

The true formation of CTB technology is inseparable from the revolutionary battery technology developed by BYD - blade battery. It is by combining the unique cuboid structure and super strength of the blade battery that BYD can derive the "honeycomb aluminum-like" structure. By rigidly connecting the blade battery pack to the car body, the two become a complete body and cancel the traditional body floor design. , integrating the floor (battery cell upper cover), battery cell, and tray with the body to form a high-strength "vehicle sandwich" structure. Not using an extra piece of material makes the layout of the vehicle more reasonable and safer. At the same time, the space inside the vehicle is better, and the safety and control coefficient are also greatly improved.

In short, the battery module under CTB technology is both the energy source and the body structure.

How about the seal equipped with CTB technology   (  parameters  |  inquiry  )?

As the world's first model equipped with mass-produced CTB technology, the Seal model has greatly improved battery safety, vehicle safety, and battery capacity. The Seal model Elk passed the test with a speed of 83.5km/h, the single-line shift test with a speed of 133km/h, and the maximum lateral stable acceleration was 1.05g.

The data is pale. Only driving experience can give you a glimpse of the strength of e-platform 3.0 and CTB technology. If you have any questions or curiosity about this technology, go to the store for a test drive in person, and you may be able to understand this technology. The essential.

Focus on consumption suggestions

Buy with your eyes closed and open with confidence. When consumers buy a new energy vehicle, the first thing they consider is the market share of the brand and model. From this perspective, BYD can indeed buy with eyes closed and feel confident. Judging from the market performance and reputation of models under e-platform 3.0, batteries based on CTB technology are also very reliable and worthy of trust.
