China is set to regulate pure electric vehicle makers' production conditions from July 10 and encourage innovative companies to join the research and production. The future EVs should have a max speed faster than 100 km/h.

The regulation said that future trial-produced EVs should number at least 15 units, with a driving range per charge no shorter than 100 km and can accelerate from 0 to 50 km/h within five seconds.

It requires that an EV maker must be a company registered in China and that it has thorough research and development experience in concept design, system and structure engineering, testing and finalizing the model.

A company is also required to have intellectual property rights in an EV, and master the core technologies in its control system, power battery system, vehicle integration and light-weight structure. And the carmaker needs to be capable of testing related technologies.
