china youth daily client news (china youth daily, china youth network reporter wang jinghui) as one of the most diverse and widely used modes of transportation, highway passenger transport has always been an indispensable option for people's travel. the "carbon peak action plan before 2030" previously issued by the state council proposed to accelerate the formation of green and low-carbon transportation methods. whether new energy buses can travel steadily and far will directly affect the progress of popularizing green and low-carbon transportation methods.
recently, catl released a new product, the catl tianxing (b)-bus version battery, which sounded the "charge" for the green transformation of the new energy bus industry. the battery has achieved a double breakthrough in battery life and energy density, extending the life cycle of new energy buses to 15 years and 1.5 million kilometers, while achieving the highest energy density of 175wh/kg for power batteries in the bus industry.
"high operating intensity, long service life and complex working conditions are the characteristics of the operating environment of new energy buses. therefore, new energy buses have very high requirements on the life, endurance, safety, reliability and scenario adaptability of power batteries." gao huan, cto of catl's domestic commercial vehicle business unit, introduced at the press conference that catl tianxing (b)-bus version can make new energy buses not afraid of long mileage and high maintenance costs, and truly achieve safe driving.
he said that behind the industry's ceiling-level parameters is the multi-level and multi-dimensional innovative technological design of catl's tianxing (b)-bus version battery.
on the one hand, the catl tianxing (b)-bus version battery improves the stacking density on a macro level to maximize the use of space, while improving the lithium ion activation rate and energy conduction efficiency on a micro level, solving the dual problems of long life and long endurance of bus power batteries; on the other hand, thanks to the complementary high-energy-density, low-lithium-consumption graphite, the exclusive additive molecule design of the highly stable interface electrolyte, and the precise film-forming technology, the battery effectively improves the life of the battery cell, allowing new energy buses to achieve "same life for the vehicle and the battery".
in terms of battery safety, considering that buses, especially buses, are prone to extreme environments such as heavy rain and urban waterlogging, the catl tianxing (b)-bus version battery has further improved its waterproof capability to ip69 level, which can withstand up to 72 hours of water immersion. in addition, the battery has also made a more innovative design at the battery management system level, introducing a 24-hour intelligent safety monitoring system, which means that whether the vehicle is in operation or not, catl's safety protection is always online.
in fact, as an important source of carbon emissions in china, the transportation industry, especially the road transportation industry, is the main battlefield for achieving the "dual carbon" goal. however, due to various technical limitations, it is difficult for power batteries in the past to fully meet the various usage requirements of buses, making new energy buses a shortcoming in popularizing green and low-carbon transportation methods.
the "opinions on accelerating the comprehensive green transformation of economic and social development" issued in july this year proposed to implement the urban public transportation priority development strategy in depth, improve the level of public transportation services, promote low-carbon transportation vehicles, and promote the electrification of urban public service vehicles.
the latest statistics show that from january to august this year, china's sales of new energy buses totaled 17,578, a year-on-year increase of 6%. it is worth mentioning that in august this year, 1,563 new energy buses (over 3.5 meters) were exported, a year-on-year increase of 164.02%.
analysts said that considering the continuous progress of battery technology, export growth and the support of the old-for-new policy, the new energy bus market is expected to continue to maintain its growth momentum. as a world-leading new energy technology company, catl began to focus on the research and development and production of power batteries in the bus field as early as 2013. it is revealed that there are more than 385,000 buses equipped with catl batteries in the world.
"the new catl b series - bus version battery is a solution tailored for new energy buses. it will fully support the upgrade of new energy buses with high-quality products and ensure that new energy buses can operate long-term and safely." the relevant person in charge of the company said that catl (b) - bus version battery has currently cooperated with 13 customers and will be developed on 80 models.
