Abstract
A method and a device for storing electrical energy by means of conversion into thermal energy and reconversion into electrical energy are described. In a pipe system as a vapor container, there is produced overheated vapor by use of electrically produced heat, said vapor transmits in turn the heat to the walls of the walls of the vapor container (1) under-utilization a thermodynamic effect, said walls transmitting the heat to the storage medium (2) by use of additionally arranged welded plates.

15. A device for storing electrical energy by means of conversion into thermal energy, comprising:
-
a vapor container; a storage medium coupled to the vapor container; a water pipe adapted to guide water into the vapor container; an electrically driven plug-in heater arranged in the vapor container to electrically produce vapor from water guided into the vapor container; and a central pipe arranged in the vapor container, the central pipe surrounding the plug-in heater and comprising a vapor outlet at an upper end and an inlet at a lower end, wherein the vapor produced by the plug-in heater circulates within the central pipe to the vapor outlet and outside the central pipe back to the inlet, wherein a thermodynamic effect transmits heat to the storage medium. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method for handling electrical energy, comprising:
-
producing vapor from water in a vapor container using an electrically driven plug-in heater; circulating the vapor out a vapor outlet and into a vapor inlet of a central pipe arranged in the vapor container and which surrounds the electrically driven plug-in heater; transmitting heat to a storage medium using a thermodynamic effect produced during the circulating step; and storing thermal energy with the storage medium from the heat transmitted in the transmitting step. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
