Abstract
At the background of the rapid economic development, China's automobile industry has made great progress.With the continuous increase in the number of the car owners, China depends more on foreign oil, causing great damage to the environment.At present, new energy vehicles have been vigorously developed in many cities and have become an inevitable choice for the development of the automotive industry.In addition, with the development of urbanization, urban logistics and express delivery industries, the demand for urban logistics vehicles is increasing.The pure electric logistics vehicles have the characteristics of zero emission,low energy consumption,low noise and so on. They are good at economical efficiency, environmental protection, driving safety and driving reliability when people use them.What’s more,they will become a kind of eco-friendly vehicles which are designed to aim at energy conservation and emission reduction. Studying logistics vehicles also satisfies the needs of national development policy and market demands, it is important for the auto enterprises to grab the commanding heights of the auto industry in the future and promote the development of China's electric vehicle industry.

This article mainly focuses on the design of the power system of pure electric logistics vehicles. It mainly includes the following parts:
（1）Recognize the characteristics of the city driving conditions and logistics as well as the cost of pure electric logistics vehicles by collecting and analyzing relevant materials.
（2）Collect and analyze the initial data of the vehicle.
（3）According to the demands of the power system design of the pure electric logistics vehicles,decide the layout of the vehicle, the power transmission system and the battery.Select the type of the power transmission motor , match the parameters of the motor,and decide the system parameters by the force analysis of the pure electric logistics vehicle.
(4) Select the type of the battery and match it’s parameters, design the layout of the power system as reasonable as possible and improve the performance of the pure electric logistics vehicle as possible as we can.
Key words: pure electric, urban logistics, power system
