Electrical energy storing system for supplying electrical motor of e.g. electric motor vehicle, has supercapacitor for recharging supplying device, where charge power load of supercapacitor is higher than charge power of supplying device

摘要

The system (3) has a rechargeable supplying device i.e. motor supplying battery (31), for electrically supplying an electrical motor, and an energy recharging device i.e. supercapacitor (32), charged by an external power source (2) e.g. recharge station, and for recharging the rechargeable supplying device. The supercapacitor has charge power load higher than charge power of the rechargeable supplying device, and is connected to the electrical motor supplying battery by a direct current/direct current converter (33). Independent claims are also included for the following: (1) a battery supplying recharging system comprising an external electric supply source (2) a method for storing electrical energy to supply an electrical motor of a motor vehicle.
