Charging station
Charging piles have similar functions to gas station tankers, and can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.). ) and parking lots or charging stations in residential areas, and can charge all kinds of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug to charge the electric vehicle.
Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe their cards on the man-machine interface provided by the charging pile and print the corresponding charging method, charging time and cost data. The charging pile display screen can display data such as charging amount, cost and charging time. By the end of June 2020, China had a total of charging piles 1.322 million, including 558,000 public charging piles, ranking first in the world.
