Chinese battery manufacturing giant CATL has unveiled a new “cutting-edge” electric bus battery that boasts an industry-leading energy density of 175Wh/kg and a lifespan of up to 15 years.
Announced at the IAA Transportation 2024 convention being held in Hanover, Germany, the CATL Tectrans Bus Edition also features “a lighter and more compact design” that has been tailor made for the electric bus industry.
The CATL Tectrans Bus Edition also claims a service life of up to 15 years, or 1.5 million kilometres, and a warranty of 10 years, or 1 million kilometres.
Local Chinese automotive website CnEVPost also reported that the Bus Edition battery has an IP69 rating capable of withstanding 72 hours of water immersion – though, one imagines greater concerns for the bus if this capacity was necessary.
CnEVPost also reported that the CATL Tectrans Bus Edition will soon be in mass production and, thanks to new partnerships with 13 vehicle companies, CATL expects the battery will soon be put to use in 80 bus models.
CATL unveiled two other batteries, including the CATL Tectrans – T Superfast Charging Edition, which boasts the capability to recharge 70 per cent state of charge in just 50 minutes, and capacity between 200kWh and 600kWh with a maximum driving range of up to 500 kilometres.
“Having stood the test of time, this product sets a new benchmark for heavy-duty truck battery endurance, with an impressive lifespan of 8 years or 1.2 million kilometres,” said Aleksej Krükov, chief engineer of CATL Overseas Business.
Similarly, the CATL Tectrans – T Long Life Edition boasts a 15-year lifespan, or 2.8 million kilometres, up to 500 kilometres of range, and hinted at the possibility of battery swapping capability.
“This product boasts an impressive driving range of up to 500 kilometers, coupled with a battery warranty that spans the entire service life of the vehicle, ensuring meticulous cost management for your business,” said Krükov.

That's some impressive numbers. Battery chemistry would have been good to know. With all the flooding going on and more expected in the future the water immersion is going to be handy.

Perhaps they will install the battery in the roof and put lead in the floor, to prevent the bus from toppling upside down into the nearest river.
Beg pardon. I misunderstood.
You mean these new batteries will make the buses amphibians? Now that's impressive!
Keep going. You have misunderstood almost every post you have replied to. Improvement is possible…
I'm surprised that gravimetric energy density is still so low. With capacity between 200 and 600 kWh, the battery mass is 1140 to 3400 kg. With more than 3 tonnes of battery I wonder what the bus weighs?
It weighs nothing. It does have weight though. Yes I complain when disinterested is used in stead of uninterested.
In this case I am trying to be humerus though!
In that case you are pulling my arm not pulling my leg!
Although not having a diesel engine, transmission and a load of fuel probably gets rid of 1,500 - 1,800 Kg at least
I think this includes some good news for many heavy truck owners.
15-year or 2.8 million kilometreslifespan is a pretty good promise for future of EVs of all sorts.
They have a long way to go before batteries become viable in the heavy truck space, bearing in mind that most long distance trucks are B Doubles.
They would probably require batteries weighing at least 10,000 kg and this eats into their available payload, making it uneconomic.
These batteries were made for Australia!
Do not forget that that Australia is for the most part a very sunny country (increasing so with climate change). Tesla seems to have no trouble selling their Cyber Trucks so there is no problem on the demand side. And in Australia trucking companies can set up their own solar farms, leading to almost free fuel with no smelly diesel fumes.
This sure beats trucking heavy diesel thousands of kilometres all over Australia.
Yes indeed.
The transportation of diesel all across the country is a lucrative business that many would be unhappy to see the end of.
Toyota will beat them with their solid-state batteries which they will release in 2019, 2021, 2022, 2023, 2025, 2027, 2028, 2029, 2031.
