Method for fast-charging a battery and device for carrying out said methd

摘要

The present invention refers to a method for fast-charging a secondary battery and to a device for carrying out said method. Fast charging is achieved by converting a DC supply voltage into a pulsating voltage which is transmitted to the secondary battery to be charged. The pulsating voltage is lead to the battery in intervals of about 10 microseconds with pauses in between of about 100 microseconds and up to 10 milliseconds.
