Toyota plans to offer more than 10 purely electric vehicle models in its range by the early 2020s, marking the Japanese car-maker's commitment to that growing technology sector.
Toyota currently offers no purely electric vehicles, although it is the leader in hybrid models, which switch between an electric motor and a gas engine.
Executive vice president Shigeki Terashi said on Monday that Toyota's EVs will be first offered in China, a country that is encouraging electric vehicles with subsidies and other policies, and is expected to drive massive growth in that technology.
Mr Terashi said Toyota's EVs will later also be offered in Japan, India, the US and Europe.
The company said that, by about 2025, every model it sells will have some kind of "electrified" version, such as hybrid, electric or fuel-cell.
Last week, Toyota announced that it will set up a joint auto battery business with Japanese electronics maker Panasonic.
Mr Terashi stressed the deal with Panasonic is "a crucial piece" in Toyota's strategy, and that it wanted to promote a Japanese partnership.
Advances in battery technology are vital for the success of EVs. A major shift toward their use would require more use and recycling of the rare and expensive materials used in batteries, such as lithium.
Toyota announced other goals on green vehicles. By about 2030, it hopes to sell 5.5 million electrified vehicles a year. Toyota sells about 10 million vehicles globally a year.
The company said it will invest 1.5 trillion yen (€11.3bn) to realise its 2030 goal, more than half of it on making batteries.
Other carmakers, including Nissan, Volkswagen and Honda, offer or are working on electric vehicles. That means competition among battery makers is heating up. It is unclear whether Panasonic will emerge the victor in the race.
Toyota has generally sought to develop key technologies in-house, rather than purchasing them from outsiders. That includes knowhow for computer chips and robotics, which are also expected to be pillars of growth for the auto sector in coming years.
