汽車設計中運動能量的獲取

　　本文以動能回收系統越來越受歡迎的技術（物）從車輛的運動獲取能量。它著眼于不同類型的技術，從飛輪雙電層電容器和超級電容器，隨著燃油效率方面的優勢，以及必要的支持高可靠性，汽車級電源管理電子捕獲，存儲和控制產生的能量。

　　從汽車系統中回收能源是下一代汽車發展的一個日益重要的組成部分。這種收獲的動能正在實現以幾種不同的方式，并與不同類型的存儲和電源管理技術耦合。

　　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.
