Around 4% of BMW China sales were electric vehicles last year.
Goller was speaking to reporters at the 2021 Shanghai Auto Show. He said BMW will have 12 electric models for sale in China by 2023.
BMW has said it expects half of its sales globally to be fully-electric models by 2030.
Goller added BMW is looking into expanding its production in China but has not made final decision. Issues at Huachen Group, parent of its main China joint venture partner Brilliance China Automotive, do not impact operations of the joint venture, he said.
