By transforming or replacing the special vehicles and equipment driven by traditional fossil energy in the airport with those by clean energy such as electricity, it can not only promote the energy saving of the airport, but also help to improve the air quality in the airport and achieve green and sustainable development. The charging solution includes both control zone and non-control zone. The control zone in the airport mainly provides charging service for special vehicles (aircraft tractor, passenger ladder vehicle, ferry vehicle etc.) and non-control zone for social vehicles.
