(1) Battery switch service should be brought into gas station. Since the distribution of gas stations is
comparatively mature and suits the urban road system well, charging services can rely on this
superiority. It will avoid repeated construction in architecture and save lots of expenses on land.
Power Supply Company may get batteries charged in off-peak hours, and transport the
fully charged batteries to gas station. In this way, the load difference between peak and valley
could be decreased.
(2) Charging piles can be installed in vehicle populated area, such as parking lots in commercial
district and residential area. It requires that the charging pile be maintained periodically which
calls for joint effort of government and charging service provider. For example, Shanghai
government has planned to set up accumulatively 5000 public charging piles in park and ride
parking places or along the road by 2015 [35].
(3) Introducing renewable energy such as wind, solar power into charging power can reduce carbon
emissions. Many customers hold suspicious attitude to the environmental performance of EV
because 79.3% of electricity is generated from coal in China. EV manufacturers should apply a
green marketing strategy to convert the trendsetters into early adopters, who will in turn lead the
market and contribute to the development of the industry’s latest selling point
