A method and a device are provided for determining the start of a charging process for an energy storage device in a vehicle, such as an electric vehicle. The method includes, but is not limited to determining at least one first parameter that indicates that a passenger is about to exit the electric vehicle. In addition, a first time tat which the charging process concludes at the earliest is determined, and a second time tat which the charging process is to have concluded at the latest is set, where t&#x2267;t. Further, a determination is made as to whether a third time tat which a lowered second energy rate relative to the first energy rate is present before the second time thas been reached, and the start of the charging process is set in such a way that the at least one third time tlies within the charging process, and the charging process concludes by the second time tat the latest.

A heads-up display comprises a monochrome display device for generating an image and an optical device for generating a virtual image from the image of the display device. The monochrome display device comprises a display and a backlight for illuminating the display from its backside. The backlight comprises a first light source emitting light of a first color, a second light source emitting light of a second color, a first light guide coupled to the first light source, and a second light guide coupled to the second light source. The first and second light guides are disposed in such close juxtaposition behind the display so that they illuminate together the entire backside of the display and illuminate a first region of the display associated with the first light guide with the first color and a second region of the display associated with the second light guide with the second color.
