With the Tesla Roadster and other plug-in（插入式）electric vehicles hitting the road, demand is growing for accessible refueling points to recharge them. Carbon Day Automotive, a Chicago-based company, has now demonstrated a solar-powered recharging point, known as the Solar plug-In Station, which lest motorists easily charge their cars using electricity that has been produced without any environmental damage.

The Solar Plug-In Station has gone on show in Chicago as part of the city’s bid to host the 2016 Olympic Games. According to Carbon Day Automotive, the Solar Plug-In Station on show in Chicago is part of the vital infrastructure （基础设施）required for electric vehicles in Chicago and was the focus of a recent visit by the International Olympic Committee.

These solar-powered electricity points will be used daily to fuel the city’s electric vehicles with power from the sun. by producing the electricity from pollution-free solar cell, the CO2 emissions are reduced to zero.

“Solar energy and electric vehicles are a partnership that is one more step to reducing our dependence on foreign oil,” says Richard Lowenthal, CEO of Coulomb Technologies. Coulomb Technologies recently developed the components （部件）required for individual recharging stations, marketed as ChargePoint Networked Charging Stations. Carbon Day Automotive is the Midwest distributor for the ChargePoint stations.

The Solar Plug-In Station consists of giant solar panels（电池板）that shade the tiny ChargePoint Networked Charging Station. The solar panel is conneceted to an underground battery pack, ready for everyday refueling.

“Without these stations it would be like driving around in traditional car without the availability of gas stations,” says Scott Emalfarb, CEO at Carbon Day. “The day of true plug-in electric vehicles will be here sooner than most people realize and the world needs to be ready to accommodate them.”
