Flywheel Battery - The flywheel battery is a flywheel (rotating mass) suitable for driving or propelling vehicles, in which a battery is integrated for weight saving purposes, i.e., a flywheel. the mass of the batter

摘要

The biggest problem with the use of flywheels and batteries in vehicle construction is the weight. This problem is currently solved in that the flywheel, in order to store the required rotational mass energy can rotate at up to sixty thousand revolutions per minute. It is relatively small and light for that. (Volvo, Kinetic Energy Recovery System) The material requirements are very high at these speeds. The weight of the batteries can be reduced for a given electrical power only by increasing the storage density. The flywheel battery alleviates these problems for electric vehicles or hybrid vehicles with electrical assistance in that the flywheel at the same time the battery or the battery is simultaneously the flywheel, resulting in a weight saving. In addition, because of its relatively high mass, the flywheel battery can accommodate very high rotational mass energies or operate at a relatively low rotational frequency, thereby reducing the requirements and cost of the material. The development of frictionless bearings (magnetic bearing, vacuum encapsulated housing) makes structures with the flywheel battery in vehicle construction, special vehicle construction and shipbuilding even more interesting.
