　　汽车设计中运动能量的获取

　　本文以动能回收系统越来越受欢迎的技术（物）从车辆的运动获取能量。它着眼于不同类型的技术，从飞轮双电层电容器和超级电容器，随着燃油效率方面的优势，以及必要的支持高可靠性，汽车级电源管理电子捕获，存储和控制产生的能量。

　　从汽车系统中回收能源是下一代汽车发展的一个日益重要的组成部分。这种收获的动能正在实现以几种不同的方式，并与不同类型的存储和电源管理技术耦合。

　　The idea of KERS， the Kinetic Energy Recovery System， started in Formula One and is now emerging in more commercial vehicles as a way of reducing fuel consumption. In Formula One the energy stored under braking is made available to the pilot， who can decide to reuse it in specific situations such as a boost when overtaking on a straight stretch， via a button.

　　An electrical system developed by Magneti Marelli in Italy connects directly to the drive shaft through a motor so that， when braking， the same shaft acts as a generator to convert the motion into electrical energy. Through the control unit， the current recharges lithium ion batteries. Under acceleration， on the other hand， kinetic energy is taken from the batteries when the pilot operates the power boost and， again through the electronic control unit， it is sent to the motor-generator. This then rotates in the opposite direction and applies an accelerating force on the drive shaft to give the boost. This system can reach up to 40，000 revolutions per minute.
