Figure 1. A kinetic energy recovery system.[1]
Kinetic energy recovery systems (KERS) are systems used in Formula 1 vehicles (ex. a race car) in order to recover kinetic energy for future use. It works by converting the energy of motion when the car decelerates (which would've been lost as heat without a recovery system)[2] into electrical energy which is stored in a battery, supercapacitor,[3] or as mechanical energy in a flywheel.[4] The driver can then press a button on their steering wheel, discharging the battery to motion of the drive shaft and giving their vehicle a boost of power.
KERS uses three main components to do its job:
- a Motor/Generator Unit (MGU): this converts mechanical energy into electricity and vice versa.
- Power Control Unit (PCU): controls the switching of electric current between the MGU and the battery.
- Storage device: which can be any of those mentioned above (battery, supercapacitor, flywheel).
The KERS uses a "charge cycle" and a "boost cycle"—the former occurring upon deceleration in order to store the kinetic energy, and the latter occurring when the driver presses the KERS button.[3]
The battery is allowed to store 400 kilojoules (111 watt-hours) per lap, giving Formula 1 drivers 82 horsepower to use for 6.6 seconds each lap.[4]
The schematic below shows how a kinetic energy recovery system works.
