- New-gen LFP bus batteries final 15 years, CATL claims—20% longer
- CATL claims a 22% enhance in vitality density by quantity, and 175 Wh/kg by weight
- Superfast Charging Version goes as much as 70% in quarter-hour
Chinese language battery provider CATL has unveiled a new battery pack for electrical buses designed to tolerate the trials of public-transit use.
The CATL Tectrans Bus Version pack, formally revealed at IAA Transportation 2024 in Germany, is designed for longer-distance passenger buses, and it has an vitality density of 175 watt-hours per kg—greater than different lithium iron phosphate (LFP) bus batteries.
It is one in every of CATL’s new Tectrans battery packs for vehicles and buses that it claims will final as much as 15 years—a 20% extension primarily based on tech enhancements—or 1.5 million km (almost one million miles), in keeping with a presentation, with a guaranty “that covers your entire automobile lifecycle,” Aleksej Krükov, the corporate’s chief engineer of abroad enterprise, mentioned Monday on the present.
In the meantime, very quick charging is a key a part of the merchandise, too. In a Superfast Charging Version, CATL claims a 70% cost in simply quarter-hour—a feat that, for fleet operators would require megawatt charging.

CATL advised present attendees that it’s at present in talks with 13 automobile producers to make use of the Tectrans Bus Version battery in as much as 80 fashions, in keeping with CnEVPost, though it is unclear if any of those shall be offered exterior of China.
The brand new-generation batteries make use of a brand new high-press-density cathode design that helps result in these packs’ 22% improve in vitality density by quantity. Within the Superfast charging version CATL has additionally labored to equalize temperatures throughout the pack.
The battery firm has a variety of potential clients, as many firms already construct and promote electrical buses world wide. Within the U.S., China’s BYD has made a number of electrical buses, as has specialist companies like Proterra and established producers of internal-combustion automobiles. Mercedes-Benz has even constructed buses with solid-state batteries that marked the primary use of that tech in a manufacturing automobile.

CATL has lengthy been a significant participant within the passenger-car EV battery enterprise, and has developed cell-to-pack tech as an alternative choice to standard battery packs that the corporate has claimed can ship an influence benefit. It is now focusing extra on commercial-vehicle purposes with the Tectrans model, which launched in July with two batteries for business vehicles, together with a long-range model and a fast-charging model that may be charged to 60% in as little as 12 minutes, in keeping with CnEVPost.
Whereas electrical automobiles get many of the consideration, electrical vehicles and buses are an necessary a part of the emissions-reduction equation. A 2021 research estimated {that a} shift to electrical vehicles and buses might save 57,000 lives by 2050 by decreasing air air pollution and its related unfavorable well being results.
