What is MTB Technology and the Benefits of CATL MTB?
In the context of dual carbon, electrification of heavy-duty trucks and construction machinery is the general trend, but they offer limited and variable space for battery placement.
On September 17, after more than a year of R&D, CATL (300750) announced that its breakthrough MTB (Module to Bracket) technology will be applied to the Qiyuan Core Power State energy investment project for the first time.
Project ". Let's discover together this technology and its advantages.
I. What is MTB technology?
MTB technology integrates modules directly into the vehicle carrier/chassis, increasing system volume utilization by 40%.
The original U-shaped water cooling system overcomes the problem of heat dissipation and offers a better solution to accelerate the electrification of heavy trucks and construction machinery.

II. What are the characteristics of CATL MTB technology?
1. CATL's ATV technology is 40% more volume efficient and 10% lighter in weight than the traditional battery + frame/chassis assembly method, increasing vehicle cargo space and improving payload weight.
2. The battery system life is improved more than 2 times compared to similar products, the life of 10,000 times/10 years, the system energy density of 305Wh/L, 170Wh/kg, providing a power configuration of 140kWh- 600kWh .
3. MTB technology adopts low frame design, the vehicle's center of gravity can be reduced by 21%, the module + system bipolar coupling with IP69K protection grade, can be used at an ambient temperature of -35℃ to 65℃.
According to CATL, next-generation ATV technology can also be applied to heavy-duty trucks and bottom-mounted construction equipment. Currently, 9 out of 10 trucks or construction machines are equipped with CATL batteries.
CATL's ATV technology is the first of its kind in the industry and can be applied to heavy-duty trucks and construction equipment, and the company will work with other partners to provide green, efficient and sustainable truck solutions. - Work and construction machinery to electrify the commercial market.
Qiyuan Core Power is a comprehensive intelligent energy service provider specializing in the field of "green electric transportation" under State Power Investment Group Co. It has fully developed more than 100 heavy-duty truck charging and switching stations in 31 provinces and cities across the country. equips more than 200 models of heavy-duty trucks on the market, and is the leading national brand of large-scale power exchange services.
In January this year, CATL took a stake in Qiyuan Core Power, becoming the company's fifth-largest shareholder.
According to the plan, Qiyuan Core Power will soon install more than 1,000 truck charging and switching stations in 31 provinces and cities in China, which can meet the demand of more than 80% of the market and about 200 models. -Exchange heavy trucks for energy exchange at any time.
Ⅲ. What is the development trend in the electrification of heavy trucks and construction machinery?
Public records show that from January to August this year, the cumulative sales of domestic new-energy heavy-duty trucks reached 13,400 units, up 319% year-on-year. Among them, August sales of New Energy Heavy Duty Trucks reached 1,847 units, up 28% year-on-year and up 127% year-on-year.
The accelerated growth in sales of new energy heavy-duty vehicles is due in part to support for heavy-duty vehicle replacement. Industry analysts say that under the combined effect of policies and market factors, the penetration rate of new energy heavy trucks will continue to increase in the future and the market will continue to be positive.
