1. A method for charging an energy storage (2) via a current generating device (3) and a charging device (4), wherein a burner (7) of the current generating device (3) is supplied with fuel from a tank (11), and wherein the burner (7) is heated in its activated state by combustion of the fuel, said combustion being controlled by a control device (6), and wherein the current is generated with a thermal element (8) by a temperature difference and used for charging the energy storage (2), one side of said thermal element (8) being connected to the current generating device (3), wherein the energy storage (2) is charged for maintaining the capacity of the energy storage (2) of a turned off, non used vehicle (5), wherein the temperature of a heat dissipating element (9) is monitored, which heat dissipating element (9) is connected to the second side of the thermal element (8), and to which the current generating device (3) is mounted, and wherein the burner (7) is controlled as a function of the measured temperature of the heat dissipating element (9).
