In recent years, as portable electronic products such as MP3, mobile phones and smart micro-universal instrumentation products, lithium-ion battery power system for the increasing demands.

近年来，随着便携式电子产品如mp3、手机和微型智能仪器仪表产品的普及，锂电池对电源系统的要求也日益提高。

The system also has the potential to use the compact engine as an electrical power source to further reduce the battery burden of dismounted soldiers, which can be as high as 11kg.

同时，使用紧凑型发动机的系统只有11公斤重，其有可能会取代电池而充当电力源，以进一步降低士兵的负载量。

The buses work by generating battery power through a regenerative braking system.

In times of low power demand, Schmitz says the the system gradually re-stores the battery power so it is able and ready to be used when the customer again needs power.

So, crawling out on a limb, he asked BorgWarner's strategy board for funds so that he and a small group of engineers could begin work on a new turbocharging system that would draw its power from the supersize battery instead of the car's exhaust system.
