Nio Energy and China National Offshore Oil Refining Company (CNOOC Refining) have signed a strategic cooperation framework agreement on Tuesday in Anhui province, eyeing to jointly build the electric vehicle charging and battery swapping infrastructure in the country.

The initiative will further leverage each other's strengths to support carbon neutrality and peak carbon goals in the country, while promoting the high-quality development of China's new energy vehicle industry, said Chinese EV startup Nio.

While no specific number of electric vehicle charging and battery swapping infrastructure to be built has been released, the two parties have so far put into operations three electric vehicle charging and battery swapping infrastructures in the country.

CNOOC has been actively planning and building integrated energy stations, gradually transitioning from an energy producer to an integrated energy service provider, said Wang Weimin, chairman of CNOOC Refining.

The company will fully leverage its strengths and experience to provide Nio with reliable sites, technology and service support, helping to boost the rapid development of the charging and battery swapping network, he said.

CNOOC Refining is a subsidiary of China National Offshore Oil Corporation, responsible for CNOOC's refining sales.
