Method for storing electrical energy in vehicle e.g. car, during driving in downhill, involves reducing potential energy at specific value around specific losses by back converting assistance of power generators into electrical energy

摘要

The method involves raising/lifting arbitrary weight (4) e.g. rock, concrete and iron, in deep water using a mechanical lifting mechanism e.g. rope hoist (2). Potential energy is reduced at a value of 9.81 WS/kgm around specific losses of an electrical energy storage device by back converting an assistance of power generators into electrical energy. The lifting mechanism is driven by an electromotor/a power generator. Stroke frequency of the lifting mechanism and power of the electromotor/generator are activated by a controller based on a desired level. An independent claim is also included for a device for storage of electrical energy.
