In allusion to the delay in the construction of charging/discharging facilities for electric vehicles (EV) and based on the practical demand on concentrated rectification of 220V AC power supply for both LED street lighting and DC charging piles for EV, an energy-saving scheme of performing concentrated rectification of 220V AC power supply and constructing DC charging piles for EV during the energy-saving renovation of urban street lighting is proposed. The integrated DC charging piles for EV widely distributed along the urban streets not only can ensure the efficient street lighting and provide convenient interfaces for charging/discharging of EV, but also possess such functions as protection, monitoring, control, communication and metering and can make the master station system convenient to implement remote monitoring and control for street lighting and charging/discharging situation of EV. Based on large-scale renovation of municipal power supply lines for street lighting it is possible to construct a wide-range low-voltage DC power supply network, in the meanwhile the new energy power generation such as photovoltaic (PV) generation and so on can be widely integrated and finally a smart urban charging network can be formed. The proposed energy-saving scheme can effectively improve the efficiency of energy utilization and vigorously promote the popularization and application of EV. Results of benefit analysis show that the proposed scheme is worthy to popularize and apply.
