Abstract

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 t1 at which the charging process concludes at the earliest is determined, and a second time t2 at which the charging process is to have concluded at the latest is set, where t2≧t1. Further, a determination is made as to whether a third time t3 at which a lowered second energy rate relative to the first energy rate is present before the second time t2 has been reached, and the start of the charging process is set in such a way that the at least one third time t3 lies within the charging process, and the charging process concludes by the second time t2 at the latest.
