CATL teases five-minute ev charging with longer range than BYD
CATL teased the latest innovations at its Tech Day on Monday (Apr 21) in Shanghai – a multi-hour event that took place in a converted warehouse on the outskirts of China's financial capital. Hundreds of media, influencers and industry watchers crowded in to hear from CATL chief technology officer Gao Huan and to catch a glimpse on the big screens of billionaire founder and chairman, Robin Zeng.
Zeng only took to the stage near the end of the event, to promise it would become an annual occurrence and remind people that CATL has 'never defined itself as a battery manufacturer but a pioneer of the clean energy system.'
Even so, one of the main products CATL talked about was an upgraded version of its Shenxing battery, a cell it says can now offer 520 km of range from just five minutes of charging time. BYD, which is primarily an automaker but which also makes its own batteries and semiconductors, recently launched a car system it says can charge a vehicle for 400 km in about the same time.
CATL batteries can already be found in a wide range of automakers' EVs. Tesla is one of its top customers and it has a technology licensing agreement with Ford Motor Its hold on the world's market for EV batteries is hard to overstate. CATL commands a share of around 38.2 per cent based on data for the first two months of the year, according to SNE Research. Its nearest competitor BYD is at 16.9 per cent.
Also a popular topic at Monday's event, taking place a few days ahead of China's annual premier auto show, were sodium-ion batteries.

CATL said its sodium-ion cell, called Naxtra, is ready for commercialisation and has been tested under a number of extreme circumstances, including very cold weather and fire. Even after being placed in an ice chamber with a temperature of minus 40 degrees Celsius, Naxtra had zero power degradation, executives said.
Naxtra should give a hybrid vehicle around 200 km of range, stretching to 500 km for an EV.
Sodium-ion batteries offer several advantages including being more cost effective due to the abundance and lower price of sodium compared to lithium. They also have higher safety and stability, considering sodium is less reactive, reducing the risk of fire hazards.
CATL also unveiled a range of dual-power batteries in a variety of chemistries and energy densities that it said offer up to a 1,000 km of range.
CATL's innovation and success in car batteries has also given it the ability to push into more ambitious areas, such as electric vertical takeoff and landing craft, or eVTOLs.
While a battery for an airborne craft wasn't a topic of Tech Day, CATL has said its eVTOL, powered by one of its electric cells, can fly up to 250 km – the equivalent of New York to Philadelphia, or Brussels to Amsterdam – at speeds of 200 km per hour.
CATL reported a 33 per cent jump in first-quarter earnings earlier this month, with net income of 14 billion yuan (S$2.5 billion) versus estimates of 13.8 billion yuan defying a drop in the prices of the cells that power EVs. Its shares are down around 13 per cent since January. BLOOMBERG

China's Chery denies improper subsidy declarations
Sign up now: Get ST's newsletters delivered to your inbox A government audit disqualified declarations by Chinese carmakers Chery and BYD for a combined S$67.8 million in government subsidies. SHANGHAI - Chinese automaker Chery on July 12 denied assertions that it had improperly claimed government subsidies for environmentally friendly vehicles. An audit by the Ministry of Industry and Information Technology disqualified declarations by Chery and BYD for a combined US$53 million (S$67.8 million) in government subsidies for thousands of vehicles sold in the five years to 2020, accounting for nearly 60 per cent of such improper claims. Chery denied its declarations were improper. It said in a statement it had previously consulted the authorities about the challenges of missing receipts because the cars were sold more than five years ago and that the government had advised the company to declare the cars for the ministry to determine if they should be qualified. 'Our company has truthfully reported to the authorities we did not collect certificates for end sales; there's no fraudulent act,' Chery said in the statement. The government's assertions do not include allegations of fraud. EV maker BYD did not respond to requests for comment. Top stories Swipe. Select. Stay informed.

Chery had 7,663 vehicles disqualified - 19 for mileage thresholds and 7,643 for not providing certificates. The audit documents did not lay out any penalties or mention reimbursement. The government has previously said automakers will have to repay subsidies for vehicles found not to have met mileage requirements. Chery said the audit covered declarations for subsidies that were not prepaid and thus automakers did not need to repay. REUTERS

BYD Sealion 6 review: A long-distance relationship
[KUANTAN] Straight after a four-day, 1,200-km road trip in Malaysia, I rushed home and smooched the wife, as married men are wont to do. 'Is that a car key in your pocket, or are you just happy to see me?' she asked, with a glimmer in her eye. To my total consternation (and her bitter disappointment), it was the key to a BYD Sealion 6 DM-i that was now sitting at Vantage Automotive. Maybe I'd subconsciously separated the Sealion 6 from its key because I felt the car deserved a bit of rest, after hauling me through half of Malaysia. That beats my wife's theory, at least, that I had it on me because I am, in her words, a 'forgetful git'. In any case, there is no rest for BYD and its five dealers this year. Having registered 3,827 new cars here in the first five months of the year, the brand has set itself a target of 10,000 sales for 2025. To hit that, it needs the Sealion 6 to succeed where no one else has. The five-seat crossover is a plug-in hybrid electric vehicle (PHEV) with a 18.3 kWh battery that can propel it for a claimed 80 km. When that runs low, a 1.5-litre engine fires up to generate electricity and keep things moving. It also helps the front-mounted motor shove the car along, if needed. That makes the Sealion 6 a kind of gateway electric vehicle (EV). The average driver here can do two days on battery power, then recharge and repeat. And when the mood strikes, long road trips are a simple matter of heading out the door with your bags and passport. A NEWSLETTER FOR YOU Friday, 2 pm Lifestyle Our picks of the latest dining, travel and leisure options to treat yourself. Sign Up Sign Up To prove the point, BYD handed a convoy of cars to the media and sent us glamping in Janda Baik, climbing the steep hairpins of cloud-covered Genting Highlands and skimming across the country to Kuantan, before trotting back to Malacca for a bit of culture. None of the six cars made it to 900 km before needing fuel, which is disappointing. Between the 60-litre tank and BYD Blade Battery under my bum, I was expecting to at least match BYD's range claim of 1,100 km. Some plain hybrid cars without plug-in technology can go that far, after all. But then they generally don't feel like EVs to drive, which is the Sealion 6's trump card. It gets underway with a smooth, silent surge, and unless you're really going for it or heading up Genting's steeper sections, you won't notice the engine waking up. To be sure, 8.5 seconds to 100 kmh isn't slow, and the instant response to the accelerator pedal makes you feel well armed for the cut-and-thrust of daily traffic. Between the leisurely steering and the general refinement, the Sealion 6 isn't a sporty car, but it's an excellent cruiser. Long days behind the wheel were a breeze, thanks to a quiet cabin, cushiony ride quality and chairs that felt like upholstered marshmallows. That said, it's not quite as plush as the Sealion 7, the newer, pure-electric crossover that has quietly become BYD's best-selling car here. Unlike that car, the Sealion 6 has no head-up display, memory seats or supple Nappa leather. But the Sealion 6 does come with a glass roof (with an actual sunshade), powerful air-conditioning, a sharp 360-degree parking camera and proper mirroring for both Apple and Android phones. It's roomy, too. The back seat is family-ready, and the 574-litre boot swallowed four journalists' gear without bursting at the seams. I'd have liked bag hooks and somewhere to stash the luggage cover, but if you ask me, the Sealion 6's biggest challenge is pricing. As a PHEV, the Sealion 6 qualifies for just S$2,500 in pollution rebates, while the electric Sealion 7 enjoys a S$40,000 discount. That means the Sealion 6 will cost slightly more than the Sealion 7, despite being older, slower, less refined and not quite as posh. That sort of maths might explain why PHEVs have never taken off here. Only about 200 of them found homes in 2024. Still, with EVs all the rage now, PHEVs might catch some of that buzz, and the Sealion 6 is very much for anyone keen on an electric car but not quite ready to break up with Big Oil yet. Yet, given that other plug-ins offered the same proposition to little success, the Sealion 6's mission isn't to conquer the PHEV market, but to establish it.

BYD, Chery among carmakers found to have claimed extra subsidies
Sign up now: Get ST's newsletters delivered to your inbox China's industry regulator found that carmakers including BYD Co. and Chery Automobile Co. claimed electric vehicle subsidies they did not actually qualify for during the five years that started in 2016. The amounts came to more than 864 million yuan (S$154 million) . Chery, the nation's largest car exporter, was found to have applied for some 240 million yuan of funding for around 8,760 EVs and hybrids that did not qualify, while 143 million yuan for roughly 4,900 cars BYD sold were removed from the ledger, according to preliminary results published by the Ministry of Industry and Information Technology (Miit) late in June . The audit of the EV subsidy program between 2016 and 2020 was carried out across China earlier this year. In Henan province, for example, a sample of 292 vehicles involving funding of 475 million yuan was assessed, according to a document published by the local government. It was not immediately clear if the companies are required to return the subsidies or if authorities have already deducted the excess amounts from payments to the manufacturers. Representatives for BYD and Chery did not immediately respond to requests for comment. Beijing is intensifying scrutiny of the auto industry, whose more than two-years long price war has started to impact the bottom lines of companies across the supply chain and raise concerns the quality and reputation of Chinese-made cars could be damaged. Some of the reasons for disqualifying the EVs in the audit included the manufacturer being unable to provide operational data for the cars, or their mileage did not meet requirements, according to documents released by the Miit.

Singapore NDP 2025: Leopard tank transmission fault identified, vehicle to resume role in mobile column Automakers, under pressure to meet sales targets, are sometimes offloading new vehicles to traders or dealers in bulk, who then help register the vehicles so the companies can book them as sales. Then the essentially brand new cars end up on the second-hand market, becoming 'zero-mileage used cars'. China's Ministry of Commerce has also convened a meeting to address this issue, and consumption subsidies in some parts of China have been paused to investigate whether dealers have used these cars to fraudulently claim rebates. China carried out a decade-long national subsidy program to promote EVs and hybrids starting in the early 2010s, offering up to 60,000 yuan per car. The rebate was paid in bulk to manufacturers, which would then discount the retail price for customers. The system provided opportunities for scams – in 2016, a People's Daily report cited estimates that dozens of companies had fraudulently claimed about 9.3 billion yuan in subsidies. Authorities have conducted audits in the past on the national EV subsidy program but usually on a far smaller scale. An audit completed in 2022 only involved a handful of carmakers and hundreds of cars. This year's audit assessed dozens of automakers and more than 75,000 vehicles. BLOOMBERG
