Porsche flywheel energy storage system

In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywh. [pdf]

FAQS about Porsche flywheel energy storage system

How does Flywheel energy storage work?

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.

What is a flywheel & how does it work?

Flywheels with the main attributes of high energy efficiency, and high power and energy density, compete with other storage technologies in electrical energy storage applications, as well as in transportation, military services, and space satellites .

How efficient is a 500 kw/100 kWh flywheel energy storage system?

The charging and discharging efficiency of a 500 kW/100 kW·h flywheel energy storage system was measured using the electric energy measurement method. The charging and discharging cycle of the flywheel energy storage system ranged from 4000 to 6000 to 4000 r/min. In the experiment, the system's charge-discharge cycle efficiency was 83.23%.

How much power does a Porsche flywheel have?

The flywheel motor in Porsche's racer had a capacity of 0.2kWh. It could deliver 163hp (122kW) for up to six seconds, offering boost for acceleration—out of corners or for passing, depending on how/when the driver decided to apply the extra power via a steering wheel-mounted button.

Does Porsche have a flywheel?

However, Porsche eventually licensed the concept from Williams Hybrid Power and set about adapting it to endurance racing in the 911 GT3 R Hybrid. Audi, too, had a go with a flywheel in its all-conquering R18 e-tron Quattro diesel-electric prototype.

How does a Porsche flywheel motor work?

Mounted in a carbon fiber box where the passenger seat would be in a road-going 911, the flywheel motor received power from, and sent power to, an 80hp (60kW) electric motor/generator at each front wheel. The configuration allowed Porsche to incorporate torque vectoring to improve handling/traction when accelerating from corner apex out.
