电动汽车充电控制系统设计(含CAD电路图原理图)(论文说明书10000字,外文翻译,CAD图纸5张)
摘 要  
 在中国电动汽车充电站的发展是必然的，抢占先机也是企业的制 胜之道。在目前的情况下，国家虽有大力倡导，各企业又蠢蠢欲动，但电动汽车走入寻常百姓家不是短期内容易做到的。国家政策可以给（购车补偿、上路等），而电动汽车充电站网则无法短期建，主要原因是给电动汽车快速充电需要瞬时强大的功率电力，常规电网无法满足，必须要建专用充电网络，这涉及整个国家电网改造，国家电网大改造不是小事，耗资巨大，从讨论、立项到成网，非一朝一夕能实现。现在能较好的解决快速充电问题的方案是-换电站-利用给汽车更换电池的方法代替漫长的充电过程。一辆汽车需要配备两块电池，当一块电池用完后自动切换到另一块，此时可到换电站将用完的电池换下，装上满电的电池。而换下的电池由电站统一充电和维护，前提是充电站要有相当数量的备用电池。这个方法优点是快速，用户换完电池就可以上路，比加油都快。用这种方法再加上停车场充电桩等辅助手段，相信电动汽车的普及就近在眼前。

The design of control system of electric vehicle charging
    Pneumatic manipulator is a automated devices that can mimic the human hand and arm movements to do something，aslo can according to a fixed procedure to moving objects or control tools. It can replace the heavy labor in order to achieve the production mechanization and automation, and can work in dangerous working environments to protect the personal safety, Therefore widely used in machine building, metallurgy, electronics, light industry and atomic energy sectors.
    This article is mainly of the pneumatic manipulator the overall design, and pneumatic design. This mechanism of manipulator includes cylinders and claws and connectors parts, it can move according to the due track on the movement of grabbing, carrying and unloading. The pneumatic part of the design is primarily to choose the right valves and design a reasonable pneumatic control loop, by controlling and regulating pressure, flow and direction of the compressed air to make it get the necessary strength, speed and changed the direction of movement in the prescribed procedure work.

 It can replace the heavy labor in order to achieve the production mechanization and automation, and can work in dangerous working environments to protect the personal safety, Therefore widely used in machine building, metallurgy, electronics, light industry and atomic .The principle, technical pare-maters, transmiting system and main parts structure of mincing ma-chine were introduced. The productingcapacity was analysed.Keywords Mincing machine Holds plate Cutting blade Transfer auger. This paper discusses the meat processing machinery - crusher working principle, main technical parameters, transmission system, the typical parts of the structure design and production capacity analysis. Small twisted paper broken machine for ordinary home, not only can be used for minced meat, can also be used with crushed peanuts, crushed ice, spices and other food, small power requirements, powered by the motor drive, reasonable structure design, can meet the family kitchen generally meat food consisting mainly of minced required.
