The extended-range electric bus is an electric bus powered by batteries and driven by pure electric power. At the same time, the range extender charges the battery to improve the cruising power. When the bus is running, it is powered by batteries to achieve environmental performance of zero emission and noise. When the battery is reduced to a certain degree, the GPS function will be used to charge the bus in the area with the best conditions in a non-populated area to achieve the best energy efficiency.
