电动汽车用动力电池的研究

能源危机和环境恶化已成为传统汽车发展的最大障碍,而发展电动汽车能够很好的解决这些问题。电动汽车不仅能够减少燃油消耗,提高经济性,而且还能降低尾气的排放,提高环境质量。电动汽车的关键技术之一是动力电池,动力电池的好坏一方面决定着电动汽车的成本,另一方面决定着电动汽车的动力性和续驶里程,这2个方面也是电动汽车与传统的燃油汽车竞争的关键所在。能否开发出性价比高的动力电池对电动汽车的未来发展具有至关重要的作用。

Study on the Power Battery of the Electric Vehicle

The energy crisis and the deterioration of the environment have become the biggest obstacle of traditional cars,while the development of electric cars can be very good to solve these problems.Electric cars can not only reduce the fuel consumption,improve efficiency,but also can reduce exhausting emissions,improve the environmental quality.One of the critical technologies of electric car is power battery,firstly,the quality of battery determine the cost,secondly,it decided power performance and driving range of electric cars,and these two factors are the keys which electric cars can competitive with conventional fuel cars.The ability to develop the cost-effective power batteries has a crucial role in the future development of electric vehicles.
