(KPL/AFP) Shares in Chinese EV giant BYD surged to a record high Tuesday after it unveiled new battery technology it says can charge a vehicle in the same time it takes to fill up a petrol car.

The company said the battery and charging system, called "Super e-Platform", boasted peak speeds of 1,000 kW, allowing cars to travel up to 470 kilometres (292 miles) after being plugged in for just five minutes.

The new technology aims to "fundamentally solve users' charging anxiety", according to BYD founder Wang Chuanfu.

"Our pursuit is to make the charging time of electric vehicles as short as the refuelling time of fuel vehicles," he said at Monday evening's launch.

Hong Kong-listed shares in BYD jumped more than six per cent to hit a fresh peak at one point Tuesday morning before paring some of the gains.

The announcement positions BYD ahead of arch-rival Tesla, whose Superchargers currently offer charging speeds of 500 kW. 

BYD introduced the Super e-Platform alongside two new EV models that will be the first to feature the system: the Han L sedan and the Tang L SUV.

The Shenzhen-based company also unveiled plans to build more than 4,000 ultra-fast charging stations nationwide to support the new technology.

The ambitious expansion comes on the heels of remarkable growth, with February sales soaring 161 per cent to more than 318,000 electric vehicles.

Meanwhile, Tesla experienced a steep 49 per cent sales decline in the Chinese market during the same period.

- Battery swap deal -

Separately, on Tuesday, Chinese EV maker Nio said it had signed a deal with battery giant CATL involving cooperation on a passenger car battery swap network.

Battery swapping offers an alternative to ultra-fast charging for vehicle owners worried about range, though the vast infrastructure required and standardisation issues present major hurdles.

The new cooperation will see CATL invest a maximum of 2.5 billion yuan ($346 million) in Nio's battery swap network.

The Chinese electric vehicle market has witnessed explosive growth in recent years, but it has also seen fierce competition among domestic car manufacturers.

Chinese EV maker XPeng on Tuesday said it is expecting deliveries to surge more than 300 per cent year-on-year in the first quarter of 2025, to a projected 91,000 to 93,000 vehicles.

That would be on par with the 91,000 deliveries the automaker saw in the final three months of 2024, according to quarterly and full-year financial results published online.

XPeng's total revenue last year was up 33 per cent compared to 2023, reaching $5.6 billion.
