"丹麦电动车车主可借由停车并且将多余电力回输至电网每年从电力公司赚取1530美元"
Nissan跟意大利最大的电力公司 Enel SpA 在丹麦做了一项试验
他们合作展示了电动车的电池是如何有助于平衡(电力)供给与需求
并且提供车主额外的收入
会有这项计划是因为随着电动车的增加，电动车所耗费的能源也会急速上升
这会给电力公司带来额外的压力
现在正在寻找适合大规模布署时的商业模式
文章中并没有说明的很清楚电动车是如何帮助电网供需平衡的
要不要开到特定地点停车或是要在特定地点特定时间停车回输电力等细节都没有提到
不过背后的原理不难猜想
就是让电动车在电力需求尖峰时刻回输电力，把电动车的电池当成储能系统用
一但他们把合适的商业模式找出来
说不定大部分的欧洲电动车车主就都能够享受到这份额外的收入呢

Parked Electric Cars Earn $1,530 From Europe's Power Grids
Electric car owners are earning as much as $1,530 a year just by parking
their vehicle and feeding excess power back into the grid.
Trials in Denmark carried out by Nissan Motor Co. and Italy’s biggest
utility Enel SpA showed how batteries inside electric cars could help
balance supply and demand at times and provide a new revenue stream for
those who own the vehicles.
Technology linking vehicles to the grid marks another challenge for
utilities already struggling to integrate wind and solar power into their
distribution system. As the use of plug-in cars spreads, grid managers
will have to pay closer attention to when motorists draw from the system
and when they can smooth variable flows.
“If you blindingly deploy in the market a massive number of electric
cars without any visibility or control over the way they impact the
electricity grid, you might create new problems,” said Francisco
Carranza, director of energy services at Nissan Europe, in an interview
with Bloomberg New Energy Finance.
While the Tokyo-based automaker has trials with more than 100 cars across
Europe, only those in Denmark are able to earn money by feeding power
back into the grid. There, fleet operators collected about 1,300 euros
($1,530) a year using the two-way charge points, said Carranza.
Restrictions on accessing the market in the U.K. means the company needs
to reach about 150 cars before they can get paid for power sent back to
the grid. That could be achieved by the end of this year, he said.
“It’s feasible,” he said. “It’s just a matter of finding the
appropriate business model to deploy the business wide-scale.’’
Electric car demand globally is expected to soar, putting further
pressure on grid operators to find new ways of balancing demand. Power
consumption from vehicles will grow to 1,800 terawatt-hours in 2040 from
just 6 terawatt-hours now, according to Bloomberg New Energy Finance.
