In the whole year of 2021, the retail sales of new energy vehicles were 2.989 million units, an increase of 169.1% year-on-year, and from January to February 2022, the cumulative sales of new energy vehicles were 765,000 units, up 154.7% year-on-year. As new energy vehicles gradually become a mainstream trend, as the core of electric vehicles, sandian technology has gradually become a link for car companies to catch up and surpass.
First, zero run released TCT battery technology
Among them, as a battery technology that is interlocked with the endurance level, it is more valued by car companies and consumers, in addition to the need to improve safety, the mechanism, density, and material of the battery pack are also the key to research and development changes, in addition, some people have made a bold attempt to launch a new energy vehicle without a battery pack.
This move is not the common Weilai, Xiaopeng, ideal, etc., on the contrary, is always relying on A00-class models to be famous for the zero-running car, on April 26, Zero Run released the world's first battery-free pack model - Zero Run C01, and CLTC mileage reached 717km, to the greatest extent to solve the user's travel mileage anxiety, to meet the needs of multi-scenario travel.
In terms of conventional cognition, mini cars = "0 technology", even if there is, it will not be a high-tech, but the move of the zero-run car this time really shocked many people, and it also branded the label of "strength faction" in everyone's mind.
Second, the interpretation of CTC structure
Battery-free pack technology is fully referred to as intelligent power CTC battery chassis integration technology. CTC technology, that is, cell-to-chassis, refers to the integrated design of the battery, chassis and car body, and the zero-run car integrates the integrated large module battery with the car body, reducing the number of parts, thereby improving the space utilization rate and energy density of the battery pack. In simple terms, it is to put the battery pack and the chassis together and throw away the original outer structure.
According to the official, the zero-run car spent seven years to create CTC technology, by eliminating the battery superstructure, reducing the redundant structural design, the vertical space of the vehicle increased by 10mm, and the battery layout space increased by 14.5%, making the space layout in the car more flexible and practical.
At the same time, the official also emphasized that based on the battery performance, the gain of the space that can be arranged and the innovation of software applications, CTC technology will increase the vehicle range by 10%, and in the future, with the continuous evolution of technology, it can achieve a high efficiency of charging for 5 minutes and a battery life of more than 200km, of course, as consumers, we must understand that the future has always been a variable topic, and it actually needs to be tested by time.
Third, what is the difference between CTP and CTP?
As we all know, BYD is far ahead in the field of new energy with its blade battery (CTP), what performance advantages does the CTC launched by zero-run cars have compared with it at this time?
First of all, the traditional battery pack is gradually composed of cell cells, modules, and battery packs, while BYD's CTP structure mainly lies in the cancellation of the composition of the battery module, directly composed of battery packs by the cell cells, eliminating the material cost of the module and obtaining more space.
The CTC structure is to directly put the battery cell into the body structure, the battery and the chassis are integrated, there is no longer a battery pack, which can also save space and material costs, improve the energy density of the battery pack, and provide more endurance under the same volume and quality.
At the same time, compared with the traditional solution, the CTC structure does not have the shackles of the outer wrapping, which can obtain better airtightness, and also has greater heat dissipation ability, which is better in safety performance.
Write at the end:
However, as with the integrated die-casting technology, if the CTC structure has an accidental collision, what needs to be repaired is the entire chassis + battery pack, which is tantamount to paying a greater cost, as a consumer undoubtedly needs to bear more concerns, and the specific safety and reliability need to be further verified by subsequent actual use.
