XPeng, which previously had CATL as its main supplier of power cells, has confirmed the use of 4C power cells from another local supplier, Sunwoda, in its midsize SUV G9, which was released last November, LatePost reported late last month.

C refers to the battery's charge multiplier, and 4C means that the battery could theoretically be fully charged in a quarter of an hour. Similarly, 3C means the battery can be fully charged in a third of an hour.

When XPeng launched the G9 on November 19 last year, it said that the car could carry a power battery with a maximum capacity of 100 kWh and a power density of 2.2 kW/kg.

The XPeng G9 is China's first production vehicle based on the 800V high-voltage SiC platform and can get a range of more than 200 kilometers on a five-minute charge, the company said at the time.

According to LatePost, Sunwoda will be the main supplier in one version of the G9, with a share of more than 50 percent.

Sunwoda started out making cell phone batteries and went public as an Apple supplier on the A-share in 2011.

In 2008, Sunwoda began manufacturing automotive power battery packages and battery management systems, and began full-scale production of battery cells in 2018.

The company has been a supplier for XPeng's G3, which went on sale in 2018, in the battery assembly segment.

Sunwoda's market share in China in 2021 was 1.3 percent, ranking 10th, according to data released in January by the China Automotive Battery Innovation Alliance, with CATL ranking first with 52.1 percent share.
