Speaking of BYD , if it is basically familiar to Chinese people, with core technologies such as blade battery and DM-i super hybrid, it ushered in its own "golden age" in 2022. Not only is its product camp rapidly expanding, car companies' monthly sales have also crushed Volkswagen North and South. Now BYD is actively developing overseas markets and has entered major industrial manufacturing countries and regions such as Japan and Europe.
The most critical reason why BYD can achieve today's market achievements is definitely inseparable from its accumulated technical strength. In addition to the blade battery and DM-i super hybrid system that consumers are familiar with, BYD now also has cutting-edge technologies in the industry such as e-platform 3.0, CTB, and high-voltage charging. The editor has also been honored to participate in the "e-chat CTB" event held by BYD recently, thus gaining some technical advantages about it.
This technology is CTB. It was first used on seals. There is a very important reason why this car can be sought after by everyone. BYD has introduced a lot of new technologies on it, including the first mass production and launch. So what is CTB?
CTB technology is a technology that BYD only officially released on May 20 this year, and is also one of the core technologies of e-platform 3.0. CTB is actually the abbreviation of Cell To Body in English. It is translated as a battery-to-body integration technology in Chinese. As the name suggests, it is to integrate the battery into the body. This is actually equivalent to a new generation of power battery packing technology. Currently, there are only a handful of car companies that have announced this technology, and the only three brands that are known to me are , Tesla , Zero-Play, and BYD.
Most of the power battery technology used in the new energy vehicle on sale are actually the second generation CTP technology, which can be roughly divided into three parts: battery cover-battery-cell-tray, namely battery sandwich structure, where the power battery is a separate whole; while the third generation technology adopts the integrated battery cover-battery-cell-tray solution on the body floor, thus forming a vehicle sandwich structure. In fact, BYD's CTB technology concept is similar to this, so it can also be regarded as a type of CTC technology.
So what are the advantages of BYD's CTB technology?
CTB As a battery body integrated technology, it is currently recognized by the industry in the future development direction of electric vehicle , because based on the higher vehicle integration, it can bring all-round improvements to the product strength of pure electric models. First of all, BYD's CTB technology borrows the design inspiration of "honeycomb", and combines the unique cuboid structure + super strength of the upper blade battery, and then adheres to the pallet and the upper cover to create a sandwich structure like honeycomb aluminum plate, making the structural strength of the battery pack reach the industry-leading level. According to official data, it can withstand the crushing of the 50-ton order.
and CTB technology also allows the wide-pack battery as a rigid body structural part to strengthen the body ring structure, so that the battery cover, battery cell and frame participate in the transmission of the vehicle's force. It not only further strengthens the chassis structure, but also increases the torsional stiffness of the vehicle by 70%, and has a 40,000+N.m/° comparable to a million-level luxury car. At the same time, it further balances the center of gravity of the entire vehicle, allowing the vehicle to have comfort and handling far exceeding its level at high speeds. For example, BYD Seals achieved a 50:50 gold axis-load ratio, which is a natural athlete.
It is worth mentioning that BYD CTB technology also has obvious advantages in the three major elements of performance, energy consumption and energy replenishment. Take BYD Seal four-wheel drive performance version for example, the price is only 286,800 yuan, but the acceleration of 000 yuan can reach 3.8 seconds, and the performance is comparable to a million-dollar supercar. At the same time, the car's energy consumption per 100 kilometers can be as low as 14.6kWh, and the CLTC pure electric range can reach 650km, which is not worse than some fuel vehicles, which is well balanced between performance and battery life. The most important thing is that BYD CTB technology can also be connected to a high-voltage electric drive boost charging solution to achieve 800V high-voltage charging. It only takes 15 minutes to charge and can last 300km, solving the endurance anxiety of pure electric models.
last point is that comfort will also be improved, because after using CTB technology, the integration of the entire vehicle will also increase accordingly, which also makes the vertical space in the car have certain advantages compared to models of the same level. Moreover, after the battery and floor are integrated, the vibration of the car can be effectively reduced, thereby improving the NVH performance in the car. These two points are also reflected in BYD Seals.
Summary: If
wants to bring consumers better products and experiences, technology updates and iterations are the only way. BYD can now be said to be ahead of the industry and has brought its own CTB technology. Judging from the advantages shown by BYD Seals, BYD's CTB technology is still very mature and has obvious advantages. Therefore, when other manufacturers are still in the stage of research and development and improvement, it is likely to become the weather vane of the next industry, like blade batteries and DM-i super hybrid systems. So what do you think of BYD CTB technology? Welcome to leave a message for discussion.
