What changes has CTB technology brought to seals? As one of the core technologies of E-platform 3.0, CTB technology greatly improves the safety and structural strength of the blade battery, so that the battery does not have to sacrifice other performance indicators. In addition, CTB technology has released the space for vehicle performance design, greatly improving the safety, handling and comfort of vehicles.
For the E-platform 3.0 model equipped with CTB technology, the safety of the interior structure in frontal collision is improved by 50%, and that in side collision is improved by 45%. In addition, CTB technology integrates the car body with the battery, which greatly improves the strength of the whole vehicle. Based on e-platform 3.0 of CTB technology, the torsional stiffness of the whole vehicle is increased by 70%, exceeding 40,000 N? m/？ . And what about the first model equipped with CTB technology? Sealed, the torsional stiffness of the whole vehicle can reach 40500N? m/？ Let the upper limit of fuel vehicle be the lower limit of electric vehicle. It is worth mentioning that the test speed of seal elk is 83.5km/h, the test speed of single lane is 133km/h, and the maximum lateral stability acceleration of steady rotation is1.05g.
In addition, CTB technology combines the car body floor with the battery cover, which can effectively suppress the vibration of the car body and improve the NVH level of the vehicle. Compared with CTP scheme, CTB reduces the vibration rate and amplitude by 90%, and the road noise 1.5dB, which makes it more comfortable, more stable and more comfortable even when crossing speed bumps and bumpy roads.
For the user space experience, the long wheelbase is only a part, and the actual cockpit space is more important. E-platform 3.0 equipped with CTB technology, the body floor and battery cover are integrated, which reduces the occupation of vertical space by batteries. In the same car, the vertical ride space is increased by 10mm, which further releases the potential of improving the interior space and allows users to have a more comfortable driving experience on low-profile models.
Compared with the zero run C0 1, the SEAL four-wheel drive version is also equipped with iTAC technology, which can improve the driving performance of the vehicle. Let's talk about this iTAC technology first.
Seal four-wheel drive version takes the first iTAC technology seal four-wheel drive version as the first model equipped with iTAC technology, which is one of the biggest highlights of seal. The full name of iTAC technology is BYD Intelligent Torque Control System, and the English name is Intelligence Torque Adaptation Control. Based on the extremely fast response speed of motors, the system can adjust the output torque of each motor in real time, minimize the change of vehicle power, and improve the safety, comfort and handling of vehicles.
Generally speaking, to maintain the stability of the vehicle, it is necessary to monitor the running state of the vehicle in real time. In the past, wheel speed sensors were mostly used to monitor the change of wheel speed. If the wheel speed on one side rises sharply, the side may slip and the braking system will start to intervene. However, the wheel speed sensor only divides each wheel end into 32 or 48 acquisition positions, so the information acquisition accuracy is low, which can not meet the requirements of electric vehicles.
ITAC technology can rotate the sensor through the motor, and each circle of the wheel end can be divided into 4096 acquisition positions, which greatly improves the speed and accuracy of information acquisition. In response speed, the iTAC recognition accuracy is improved by more than 300 times, and the wheel speed change trend can be predicted more than 50ms in advance. When the wheel grip is abnormal but not slipping, the system has recognized the abnormal grip and adjusted it in advance to restore the stability of the vehicle.
In the control strategy, the traditional control strategy can only control the vehicle by braking to reduce the torque when facing skidding. On the basis of pre-judgment, iTAC provides a variety of ways to transfer torque, appropriately reduce torque and output negative torque according to the characteristics of fast motor response and more accurate speed regulation.
(iTAC controls the vehicle through torque transmission)
According to the official measured results on low adhesion roads, iTAC can prevent vehicles from slipping when accelerating in a straight line from 0 km to 60 km in snow, and the acceleration time is 0.7 seconds faster than that of vehicles without iTAC function. When the ice-asphalt pavement starts, iTAC technology greatly inhibits the wheel end slip and the vehicle leaves the ice quickly; In the snow corner step test project, iTAC keeps the vehicle in a stable driving state, and the body slides smoothly and linearly; In the snow circle test project, iTAC technology can keep the vehicle drifting and improve the speed by 5- 10 km/h without too much direction correction.
According to official information, iTAC technology seems to be very helpful to improve the driving and handling performance of vehicles. But is there really such a huge improvement in actual driving? Let's put a question mark for the time being, so please look forward to our follow-up measured experience.
What changes have CTC technology brought to zero run C0 1? According to the official information from Zero Run, taking the first Zero Run C0 1 equipped with CTC technology as an example, the number of parts is reduced by 20%, and the vertical space is increased by10 mm; ; The battery layout space is improved by 14.5%, and the comprehensive endurance is improved by10%; The cost of structural parts is reduced by 15%, and the lightweight coefficient is increased by 20%.
In terms of space, in addition to CTP battery technology (Contemporary Ampere Technology Co., Ltd., BYD), the existing VDA standardized module still has some problems, such as a large number of parts, low structural efficiency and low battery utilization rate.
Zero-run CTC technology sets the cabin structure under the car body, seals the upper end of the cabin body, cancels the upper structure of the battery, increases the vertical space of the whole car by 10 mm, saves the reserved gap between the battery side frame and the car body, and increases the layout space of battery capacity.
With the increase of battery layout space, more batteries can be inserted, with better space utilization and stronger battery life and performance. The lower end of the carriage adopts a bowl-shaped battery tray to form a sealing structure with the car body, and the battery module is placed in the carriage.
In addition, CTC technology adds the structure of heat insulation layer to the battery tray, which can keep the battery warm at low temperature and avoid the battery temperature from being too low. Triangular force transmission guide blocks are also designed on the side of the battery compartment. When the vehicle is hit by a large side, the lateral force is converted into a longitudinal force, which is transmitted to the front and rear body longitudinal beams to avoid the deformation of the supporting beams between modules, thus damaging the battery cells.
Since the battery is a structural part, it must be the stressed part of the car body. General Manager of Zero Run Technology Battery Product Line? Song Yining said that taking the zero-run C0 1 car as an example, CTC technology can improve the body stiffness by 25%, reduce the generation of * * * vibration, and the NVH performance will be better.
At the same time, the battery management system based on AI BMS can carry out real-time online detection, real-time fault monitoring, early warning of thermal runaway, and analysis of charging habits. In addition, CTC technology can also be compatible with 800V high-voltage platform and 400kW fast charging, which is very common in different models on the same platform.
In terms of power exchange, Zhu believes that if the country has been unable to issue a unified standard and only relies on a car company to promote it, it will be difficult to form a scale effect. However, from the information exposed, Zero Run applied for the patent of wireless battery pack first, which also shows the "hypocritical" side of technology-based enterprises. Zhu also believes that skateboard chassis is not suitable for private car models, and the logic is similar to that of non-loaded vehicles. Generally speaking, CTC battery chassis integration technology is the best scheme for zero running of power battery route.
Next, except T03 and C 1 1 models currently on sale, all models will adopt CTC battery chassis integration technology. Among them, the first zero-run C0 1 with CTC technology has been pre-sold, and it is expected to be officially launched in August, delivered in small batches at the end of August and delivered on a large scale in September.
Who looks better? From the appearance outline, the seal highly restored the Ocean-X concept car. Different from the dragon face design language of BYD dynasty series in the past, the new car adopts a brand-new marine aesthetic design concept, which makes it look younger, more sporty and lower.
? Natural aesthetics of science and technology? It is the design concept of zero run C0 1. The new car abandons the complicated line design and adopts a lot of powerful contours to make the overall shape smoother and more natural.
It is reported that every reduction of drag coefficient Cd by 0.0 1. The driving range of pure electric vehicles can be increased by 8 kilometers. This has prompted these two models to lock in lower aerodynamic performance targets at the beginning of development. Seal reduces the wind resistance by reducing the height of the front engine room and the streamlined surface design, and the wind resistance coefficient is 0.2 19 Cd, while the wind resistance coefficient of Zero Run C0 1 is 0.226Cd with the help of streamlined design and hidden door handle.
The exterior design of the two cars is excellent, and the shape of the big slip back is full of movement, which brings us a sense of surprise. As for who is better, people have different opinions.
Expand the rest of the full text (1/2) 2 Two-car intelligent cockpit/space comparison Back to the top whose cockpit is smarter? In terms of interiors, seals have continued? Marine aesthetics? The design concept adopts the combined layout of 10.25-inch full LCD instrument+15.6-inch adaptive rotating floating pad, embeds the latest DiLink intelligent network connection system, and supports 5G network connection. In addition to the regular functions, it also supports very mainstream functions such as voice command, remote control, clairvoyance, mobile phone interconnection, NFC car key, VTOL discharge, etc., and its practicability is still very high.
The zero-run C0 1 adopts T-shaped three-screen design, which supports three-screen linkage, independent Bluetooth access of the auxiliary driving screen and three-screen intercommunication of music. Using Qualcomm SA 8 155P digital cockpit chip, the 3rd and 5th generation speech recognition system in Iflytek can recognize most natural speech commands.
What is worth mentioning is the seal DiLink intelligent network connection system? Clairvoyance? The function is to allow users to call the cameras inside and outside the car through the BYD cloud service App on the mobile phone. However, if the user is worried that the opening of the camera in the car may cause privacy leakage, the EU can be directly covered by the physical slider. In addition, the DiLink R&D team has also carried out strict security tests, and built a perfect security system through security chips, security gateways and bus encryption.
In terms of intelligent assisted driving, seals are equipped with five millimeter-wave radars, 12 ultrasonic radars and four 360? Look around the camera and the front perception monocular camera. The top version will be equipped with two side-sensitive cameras above the fenders on both sides, which is quite unexpected. This is also BYD's first model equipped with a side-sensitive camera. In addition, from the hardware point of view, SEALs will be equipped with high-speed pilot-assisted driving for the first time, which is similar to Tesla NOA and Tucki NGP.
Zero run C0 1 adopts the same hardware configuration as zero run C 1 1 and is equipped with Leap Pilot 3.0 intelligent assisted driving system. On the hardware level, C 1 1 * * is equipped with five millimeter-wave radars, 12 ultrasonic radar and1/camera. The driver assistance chip is equipped with Lingxin 0 1, and its single operation capability is 4.2 TOPS. According to the official, more than 22 intelligent assisted driving functions will be opened in the future.
Comparison of hardware parameters/models of intelligent driving assistance for two cars BYD Seal Zero Run C0 1? Ultrasonic radar 12 12? Millimeter wave radar? 5 5? Front perception camera? Monocular camera, binocular camera? 360? Look around the camera. 4 4 side sensing camera? 2 4? Note: Data source tabulation: Who has more space?
As for the actual ride space, there is no ride experience of running C0 1 for the time being. Therefore, the following sealing effects are for reference only.
In fact, the two cars have reached the leading level at the same level in terms of technical highlights, design concepts, intelligent driving assistance configuration and battery life. Thanks to iTAC technology, the handling performance of seal is worth looking forward to. Coupled with BYD's strong supply chain, it is expected that the waiting period will not be too long. The car length of 5050mm and the wheelbase of 2930mm in the zero-run CO 1 body size part are also relatively capable of playing, and the visual performance of the space will not disappoint. In any case, I look forward to the response after the two cars go on the market. As for how to choose, it depends on the price after listing, car purchase policy and delivery time, and then we will know who is dead and who is alive! (Photo/Text/Photo: Uchi Bomin)
