EV Charging infrastructure in China

  • The charging point mainly applies slow

charging mode with low current, concerning to the safety and battery life cycle.

  • Charging point covers less areas,

approximately 1 m2, and costs less as well.

  • However, long time of charging could

not meet the instant use requirement.

EV Charging infrastructure in China

  • The charging station with fast charging mode

is more efficient and time-saving in charging. It would charge 50%-80% of electricity in 10-30 minutes.

  • Whereas, the construction and management
  • f charging station are relatively higher,
  • Present battery technology is not fully

developed, thus the fast charging mode has great potential hazard on battery.

EV Charging infrastructure in China

  • Due to the electricity would be supplied by charging and

battery swapping, hence the construction of charging station have much more flexibility than conventional gasoline station.

  • by construction and structure, the charging station could be

divided into: 1.Integrated Battery Swapping Station 2.Master-servant Battery Swapping Station 3.Parking Vehicle Charging Station

  • Master-servant Battery Swapping Station
  • Low-electricity battery are gathered to charge all together in the master work station,

while battery swapping is executed servant work station.

  • The distribution system transfers fully charged battery to servant work station and

returns low-electricity battery to master work station. It could also provide emergency charging service.
