Volkswagen AG’s Audi luxury-car brand is in talks to add China’s BYD Co. as a supplier of batteries used in its premium electric vehicles, according to people familiar with the matter.

Negotiations with Warren Buffett-backed BYD, China’s top electric-car manufacturer and No. 2 auto-battery supplier, are at an advanced stage, the people said, asking not to be identified because the talks are private. BYD is also in discussions with other automakers about battery-supply deals, one of the people said. There’s no guarantee that an agreement with Audi will be reached.

Carmakers are seeking to diversify supplies of critical components as the rollout of electric models gains traction. VW plans to deliver 22 million fully electric vehicles worldwide by 2028, with more than half of them built in China, where BYD makes batteries. Audi currently uses battery cells from Contemporary Amperex Technology Co. Ltd. for its Q2L e-tron sport utility vehicle sold in China.

In May, concerns over a battery supply deal with Samsung SDI Co. unraveling in Europe pushed VW to rework details after pledged supplies shrank to less than five gigawatt hours from just over 20 gigawatt hours. For BYD, teaming up with a global luxury brand like Audi will help it take on bigger rival CATL. The two Chinese companies are emerging as challengers to Tesla Inc. suppliers Panasonic Corp. and LG Chem Ltd.

BYD’s batteries would be used to equip upscale cars made on the Premium Platform Electric architecture jointly developed by Audi and Porsche, said one of the people. The first models are slated to hit the market around 2021.

An Audi spokeswoman said the company is in talks with several manufacturers, and no decision has been made. BYD didn’t have any information to disclose at this point, according to a spokeswoman.

Audi and BYD had also explored options for deeper ties including a development joint venture or acquiring a stake in the Chinese supplier’s battery unit, the people said. It’s unclear how far those talks progressed, they said.
