Formula 1 as a sport has been completely transformed over the years into a billion dollar business. The sport has become highly popular with a broad global audience base and has been attracting a number of multinational companies.
Formula 1 has a long-standing history of providing technological developments, which are applicable not only to fast racing cars but also to the general automotive industry. One such development is the Kinetic Energy Recovery System also called regenerative braking that has become a familiar subject in technical universities and automobile companies.
What is KERs?
一级方程式赛车的运行释放动能，并且刹车的应用将其转化为大量的热能，这些热能正常被浪费。在配备KER的汽车中，这是不一样的。使用KERS系统，当驾驶员施加制动器时，该动能将转换为电能。
Formula 1 cars have an electric motor and batteries set-up that is used for converting and storing the energy in the car. At one end of the engine crankshaft, the electric motor is mounted. The application of the brakes causes the electric motor to capture a portion of the rotational force and converts the kinetic energy into electrical energy, which is stored in the battery bank.
The pressing of the boost or KERS button by the driver causes the stored energy to be converted to kinetic energy giving the Formula 1 car additional horsepower for a limited duration.
最初，该系统是在2009年推出的，很少有F1团队使用该技术。克尔斯（Kers）在2010年被禁止，但在2011年再次引入，目前正在大多数F1团队使用。KERS系统可能有点沉重，增加了35公斤，为F1汽车余额提供了挑战，它确实为驾驶员提供了大约80 bhp的额外额外的额外额外额外的费用，每圈大约6.67秒。

The release of this extra capacity may be done at one go or at different points providing the driver an additional advantage during overtaking or defending positions. The KERS system is not only intended to help in overtaking/defending to create additional excitement in the race, but is also a step towards bringing the sport close to "greenness".
测试KERS系统
The high precision power analyzers of Yogokawa are used in the development of KERS in the F1 industry. Engineers can test several parameters in both R&D and production of the KERS system. Electric motor testing is a key application area for Yokogawa's high precision WT1800 and WT3000 power analyzers.
Users are assisted in measuring electrical output, efficiency and losses in electric motors. The ability to connect 6 power inputs to a single WT1800 helps customers to evaluate motor input/output efficiency. Furthermore, the motor evaluation function simultaneously measures voltage, current and power as well as changes in rotation speed and torque derived from sensors. These sensors also enable the direction and shaft power to be measured.
The 6 inputs of the WT1800 also help customers to evaluate the battery charge and discharge characteristics, and the inverter's efficiency. The Yokogawa WT3000 is the world's most stable and accurate power analyzer providing the highest guaranteed accuracy of 0.02%.

Conclusion
一级方程式技术中KER的技术的成功是基于所有资源的效率。高精度电源分析仪是将R＆D和生产单元构建有效系统的关键产品。
