battery power

基本解释

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.
但对电动汽车来说这尤其是个好主意，因为如果车子仍然插在插头上，就可以使用市电，因而节省电池电力。
GM recently revised the Volt's range on battery power to 25 miles (from 40) but it doesn't really matter if you've got the gasoline engine to keep you going.
通用汽车公司最近将沃蓝达的电池电源范围修改为25英里（40），但如果你有汽油引擎保持行驶，这并没有多大影响。
The new development here is the plug-in hybrid, the battery of which can be re-charged at home as well as on the road, offering longer range driving on pure battery power.
新开发的一款为插电式混合动力车，电池能像在路上一样在家里进行充电，这样就可以依靠纯电池动力行驶更长的距离。

The only evidence is a battery pack and a power line on his side.
Imagine how much power it takes to drive an artificial heart, so you've got to have a battery or some way of generating power continuously to operate that and that makes it difficult to think about implantable and so that's a really good example of Biomedical Engineering.
驱动人工心脏所需要的能量是难以想像的,所以需要电池或者是某种持续发电装置,来给人工心脏提供能量,这就增加了人工心脏的植入难度,这是很好的生物医学工程的例子
