Chinese EV industry pits battery swapping technology against ultra-fast charging

'Carmakers and consumers now have two options as they choose which kind of EVs to buy,' said Davis Zhang, a senior executive at Suzhou Hazardtex, a supplier of specialised batteries, in an interview last week. 'Each of the technologies has its own advantages and disadvantages, but they will coexist over a long period of time.'
The battery swap model allows EV owners to exchange a spent pack for a fully charged one in just 100 seconds. And fast-charging technology gives a vehicle 400km of driving range in five minutes.
CATL plans to build 1,000 stations to support battery swapping in China this year. At the end of 2024, Robin Zeng Yuqun, the company's founder and chairman, said CATL had secured subscription orders for 107,500 of its Choco-SEB swappable batteries from more than 30 companies.

Nio and CATL showed off their latest product offerings at the Auto Shanghai trade show, which ends on Friday. But they are grappling with
BYD to attract visitors at the show. The world's largest EV builder – also a battery maker – had on display its Han L and Tang L vehicles that are supported by its Super e-Platform, which offers peak charging power of 1,000 kilowatts (kW) or 1 megawatt (MW). The Shenzhen-based company started deliveries of the two models last month.
Battery swapping has the potential to save a car buyer as much as 40 per cent of the cost of owning a new EV – amounting to 40,000 to 50,000 yuan (US$6,876) – because they can rent batteries from the carmakers or other firms.

CATL leaves lithium mine idle in Yichun amid looming glut of China's EV battery producers
Contemporary Amperex Technology's suspension of production at a major lithium mine in mainland China is a clear sign of Beijing's aggressive stance towards curbing overcapacity in the electric vehicle (EV) battery sector, according to analysts. The world's largest producer of EV batteries, known as CATL, said on Sunday evening that the licence for the mine in Yichun, in China's central Jiangxi province, had expired on Saturday. It added that an application for restarting operations had been submitted and said the temporary production halt would have only a limited impact on the company's businesses. 'The production halt could be a result of Beijing's efforts to curb excess capacity in the EV battery industry,' said Ding Haifeng, a consultant at Shanghai-based financial advisory firm Integrity. 'But it remains to be seen whether the government will take further steps to limit the output of lithium.' A view of CATL's lithium mine in Yichun, Jiangxi province.

Lithium carbonate contracts on the Guangzhou Futures Exchange jumped by the daily limit of 8 per cent to 81,000 yuan (US$11,279) a tonne on Monday. Citigroup analysts said in a report on Monday that a 10,000 yuan per tonne increase in the price of lithium could cause CATL's profit margin, which stood at 22.4 per cent at the end of June, to drop by 4 percentage points.

Nvidia, AMD 'to pay 15pc China sales revenue to US'
Nvidia, AMD 'to pay 15pc China sales revenue to US' Nvidia CEO Jensen Huang is said to have agreed on the 15 percent deal in a meeting with US President Donald Trump on Wednesday. File photo: Reuters US semiconductor giants Nvidia and Advanced Micro Devices (AMD) have reportedly agreed to pay the US government 15 percent of their revenue from selling artificial intelligence chips to China. Nvidia CEO Jensen Huang met with US President Donald Trump at the White House on Wednesday and agreed to give the federal government the cut from its revenues, a highly unusual arrangement in the international tech trade, according to US media outlets, including Bloomberg and the New York Times on Sunday. Investors are betting that AI will transform the global economy, and last month Nvidia – the world's leading semiconductor producer – became the first company ever to hit US$4 trillion in market value. The California-based firm has, however, become entangled in trade tensions between China and the United States, which are waging a heated battle for dominance to produce the chips that power AI. The United States has been restricting which chips Nvidia can export to China on national security grounds. Nvidia said last month that Washington had pledged to let the company sell its H20 chips to China, which are a less powerful version the tech giant specifically developed for the Chinese market. The Trump administration had not issued licences to allow Nvidia to sell the chips before the reported White House meeting. On Friday, however, the Commerce Department started granting the licences for chip sales, the reports said. Silicon Valley-based AMD will also pay 15 percent of revenue on Chinese sales of its MI308 chips, which it was previously barred from exporting to the country. (AFP)
