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.
