The government plans to allow companies to sell electric two and three wheelers without batteries to "create an ecosystem" for clean transport, said a notification on Wednesday. EVs can be registered for use without a battery, too.

The battery, which accounts for 30-40 per cent of the total cost of a vehicle, could be provided separately by the original equipment manufacturer or the energy service provider, said the transport and highways ministry in a notification to states.

The step will make the upfront cost of the vehicles to be lower than ICE two-wheelers and three-wheelers.

The ministry said the vehicles without batteries can be sold and registered based on the type approval certificate issued by a test agency. It said there is no need to specify the make/ type or any other details of the battery for registration.
