Abstract:Air pollution caused by traditional vehicle emissions and the Earth's greenhouse effect, is an important source of environmental pollution. Integration of a variety of contemporary high-tech and the rise of pure electric vehicles, hybrid electric vehicles, fuel cell vehicles, in particular based on the hydrogen fuel cell vehicle based on the auto industry is causing a revolution in the world, demonstrated the new energy automotive industry, new impetus to the development of a bright future.

　　　Electric cars have no emissions of pollution, low noise, easy manipulation, maintenance and operation and low cost, in environmental protection and energy conservation with incomparable advantages, it is great to solve the energy and the environment of human pressure on the most effective way. Therefore, the electric car is the car's development in the 21st century, researchers developed a number of domestic and international electric vehicle batteries.

　　　Battery electric vehicles as the key enabling technologies, and their importance is questionable. From lead-acid batteries, nickel cadmium batteries to nickel-hydrogen batteries, lithium-ion batteries and fuel cells, to today, its technology has reached a certain bottlenecks. The electric cars need high-capacity, long cycle life of the needs to promote its existing technology based on research in other aspects of study, such as series and parallel way, different types of hybrid battery, the battery pack and other aspects of packaging, demand breakthrough.

　　　Purpose of this study is to examine the existing cell group package design, analyze the advantages and disadvantages, on this basis, to continue to explore and deepen research, in order to find a new program to address the existing set package Deficiencies of Department, to promote the battery industry to develop electric vehicles to a higher level.
