Renault 2014 Power Unit

An Energy Store (ES) is a component of the hybrid power unit used in Formula 1 racing. The ES is responsible for storing energy that is recovered from the car's braking system, and then using that energy to boost the car's performance.

The energy recovery system in Formula 1 is known as the MGU-K (Motor Generator Unit- Kinetic) and it captures the energy that is generated when the car brakes. This energy is then stored in the ES, which is typically made up of a battery pack. The stored energy can then be used to power the MGU-H (Motor Generator Unit- Heat) which is connected to the turbo charger and helps to increase the speed of the compressor, this results in more power for the car.

The use of energy recovery systems, such as the ES, is highly regulated by the FIA, the governing body of Formula 1 racing. Teams are only allowed to use a certain amount of energy per lap, and they must also follow strict rules about the design and construction of their energy stores.

The Energy Store is a crucial component of the Formula 1 car's hybrid power unit as it allows teams to recover energy from the braking system and use it to boost the car's performance. This is a highly advanced technology that allows teams to gain an advantage on the track and improve their lap times. Teams invest heavily in the development and testing of their Energy Stores to ensure they are reliable and deliver as much as possible performance.

In summary, an Energy Store (ES) is a component of the hybrid power unit used in Formula 1 racing, it is responsible for storing energy that is recovered from the car's braking system, and then using that energy to boost the car's performance. The use of energy recovery systems, such as the ES, is highly regulated by the FIA, to ensure a fair competition among all teams, and teams invest heavily in the development and testing of their Energy Stores to ensure they are reliable and strong.
