Why doesn't Beijing let go of pure trams?

The charging facilities are not perfect enough, and the cruising range is problematic.

1, charging facilities are not perfect: pure electric vehicles need charging facilities, including charging piles and charging stations. In Beijing, due to the relatively backward construction of charging facilities, it cannot meet the demand of large-scale pure electric vehicles.

2. Battery cruising range: The cruising range of pure electric vehicles is an important consideration. Despite the improvement of battery technology, the cruising range of pure electric vehicles is still relatively limited, which cannot meet the needs of long-distance travel.
