What is MTB technology and the advantages of CATL MTB?

    Under the background of double carbon, the electrification of heavy trucks and construction machinery is the general trend, but they give limited and diversified space for battery arrangement. On September 17, after more than a year of research and development, CATL (300750) announced that its pioneering MTB (Module to Bracket) technology will be first applied to the "Qiyuan Core Power" project of State Power Investment "Power Exchange Project". Next, let's learn about this technology and its advantages together.

    I. What is MTB technology?

    MTB technology integrates modules directly into the vehicle bracket/chassis, increasing the system volume utilization by 40%. The original u-shaped water cooling system overcomes the problem of heat dissipation, providing a better solution to speed up the electrification of power-exchange heavy trucks and construction machinery.

    II. What are the advantages of CATL's MTB technology?

    1.CATL's MTB technology is 40% more efficient in volume and 10% lighter in weight than the traditional battery pack + frame/chassis assembly method, which increases the vehicle cargo space and improves the cargo weight.

    2. the battery system life than similar products to improve more than 2 times, cycle life of 10,000 times / 10 years, the system energy density of 305Wh / L, 170Wh / kg, providing 140kWh-600kWh power configuration.

    3.MTB technology adopts low frame design, the whole vehicle center of gravity can be reduced by 21%, module + system bipolar seal, with IP69K protection level, can be used in -35℃ to 65℃ ambient temperature.

    According to CATL, the new generation of MTB technology can also be applied to bottom-mounted rechargeable heavy trucks and construction machinery. Currently, for every 10 heavy trucks or construction machinery, 9 of them are equipped with CATL power batteries.

    CATL's MTB technology is the first of its kind in the industry, and it can be applied to the bottom-mounted rechargeable heavy-duty trucks and construction machinery, and the company will work together with more partners to provide green, efficient and sustainable solutions for rechargeable heavy-duty trucks and construction machinery to help the commercial market go electric.

    Qiyuan Core Power is a comprehensive intelligent energy service provider focusing on the field of "green electric transportation" under State Power Investment Group Co. It has fully laid out more than 100 heavy truck charging and switching stations in 31 provinces and cities across the country, adapting to more than 200 models of heavy trucks on the market, and is the leading domestic brand for large-scale power exchange services.

    In January this year, CATL took a stake in Qiyuan Core Power and is the fifth largest shareholder of the company.

    According to the plan, Qiyuan Core Power will lay more than 1,000 heavy truck charging and switching stations in 31 provinces and cities in China in the near future, which can meet the demand of more than 80% of the market and about 200 models of power-exchange heavy trucks for power exchange at any time.

    Ⅲ. What is the development trend of heavy trucks and construction machinery electrification?

    Public data shows that from January to August this year, the cumulative sales of domestic new energy heavy trucks reached 13,400 units, an increase of 319% year-on-year. Among them, the sales of new energy heavy trucks reached 1,847 units in August, an increase of 28% from a year earlier and 127% from a year earlier.

    The accelerated growth of new energy heavy truck sales comes partly from the support of the power exchange heavy truck. Industry analysts say that under the combined effect of policies and market factors, the penetration rate of new energy heavy trucks will continue to rise in the future, and the market will continue to be positive.
