混合电力推进系统及其贮能电池

Hybrid electric propulsion system and its storage energy battery

混合电力推进系统,由于利用了热机比能量高和蓄电池比功率高的特点,并可回收一部分动能,从而提高了推进系统的总效率,降低了对环境的污染。当选用蓄电池作为贮能装置时,应当根据推进系统的组合方式、设计要求、蓄电池的性能和价格来综合考虑。

Hybrid electric propulsion system would be so excellent that the total energy efficiency of which would be improved and the air pollution decreased as well, by taking advantages of the high energy density of heat engine and the high power density of battery, and regenerative-braking uptake. It would be necessary to take into account of the combining manners of the propulsion system, design demands, performances of batteries, in order to select some battery as storage energy equipment.
