The eBUS-12 buses, built by local company BYD, have undergone a series of testing in the cities of Shenzhen and Changsha since January, which resulted in saving approximately 322 kilograms of carbon emissions per day and US$2,833 per month.

Buses will be charged over night when electricity rates are off-peak, and will be able to run for 250Km when fully loaded with passengers. Other favorable characteristics include the short charging time needed to reach 50% of total charge, just 30 minutes, and solar panels mounted on the roof to recharge and stock electricity in the battery for air conditioning.
At the conclusion of the Games, Shenzhen will add them to its regular fleet of buses, making it the largest electric bus fleet in the world.
