Plug-in versions of toyota 's prius hybrid will allow that ground-breaking vehicle to be charged from a mains socket .

插电版的丰田prius混合动力车将允许这种开创性的车辆通过电源插座来充电。

If that proves possible , though , it will just be a question of plugging your jacket into the mains to charge it up , and then boogying .

如果这成为可能，那么问题就只剩下把你的衣服与电源接通充电，然后跳舞了。

Once procured and consumed , mr reqabi must then pay for eight hours of mains electricity , since the meter in his factory does not distinguish between different sources of power .

一旦燃油用完，reqabi先生必须要支付8小时的电费，因为其工厂的电表并不能区分电源的不同。

But it is a particularly good idea for an electric car because mains electricity can be used if the car is still plugged in , thus conserving battery power .

而对于电动车而言，这尤其是个好主意，因为如果车辆仍在充电则可以使用电源这样就节约了电池的电力。

Range-extenders like gm 's volt ( the ampera in europe ) are powered by an electric motor that can be recharged either from the mains or by an on-board internal-combustion engine .

里程扩增如gmvolt（也就是欧版ampera）是由电动马达驱动，并可以从电源或者机载内燃机充电。
