Energy Recovery System

from Wikipedia, the free encyclopedia

Energy Recovery System ( ERS ; German energy recovery system ) is a system for energy recovery approved in Formula 1 from the 2014 season . In contrast to the Kinetic Energy Recovery System used until 2013 , which is only based on the energy recovery of kinetic energy , the ERS consists of two systems: A system called ERS-K for the recovery of kinetic energy using the Motor-Generator-Unit-Kinetic ( MGU- K ) named generator and a system named ERS-H for the recovery of energy from the exhaust gas flow, see Heat Energy Recovery System , with the aid of a generator named Motor-Generator-Unit-Heat ( MGU-H ). The electrical voltage of the system is limited to 1000  volts .

Mode of action

According to the FIA, the two-part energy recovery is intended to compensate for the new fuel limit of 100 kg per race, 105 kg since 2017 . Both energy recovery systems lead to a central energy storage device with a minimum weight of 20 and a maximum of 25 kg, the energy of which is managed by a central control unit and flows back into the drive train.

  • The ERS-K uses the braking energy for energy recovery. The rotational speed of this gear connected to the electric motor / generator unit is at 50,000 min -1 limited. The maximum torque of 200 Nm must not be exceeded. The energy consumption is limited to a maximum of 2  megajoules per lap. The driver is only allowed to use MGU-K if his vehicle is over 100 km / h (excluding take-off).
  • The ERS-H indirectly uses the exhaust heat from the engine. This electric motor / generator unit must be mechanically connected to the exhaust gas turbocharger and must not exceed a speed of 125,000 min −1 . The energy consumption is not limited.

The ERS is limited to 120  kW of power, which is available to the driver for 33 seconds per lap. That is ten times the energy (4  megajoules ) of the 60 kW and 6.7 seconds (400 kilojoules ) allowed before 2014  .
