TIANJIN - Volkswagen China said on Monday that it expects electric vehicles to account for up to 25 percent of its total auto production by 2025.

Vehicles driven purely by electricity will sell two to three million units by 2025 as Volkswagen expands its electric vehicle line to over 30 models in the next 10 years.

Batteries for electric vehicles could emerge as a new source of income, the automaker said, adding it is evaluating the research needed and potential income.

The automaker will continue to expand its business in China, such as customized auto services either through in-house research or acquisition.
