Abstract

The invention relates to a method for generating control information during the operation of a working device system, which comprises electrically driven working devices for carrying out a working operation, a rechargeable battery assembly consisting of rechargeable batteries for supplying energy to the working devices, and an electrical charging device for the rechargeable batteries. Energy requirement prediction information is determined, and the energy content of the rechargeable batteries for supplying energy to the working devices for carrying out the working operation is also determined. According to the invention, a device / rechargeable battery combination is determined according to an optimization criterion for carrying out the working operation, and an associated optimal charging plan for charging the rechargeable batteries is determined, specifically while taking into account the determined energy content of the rechargeable batteries, the energy requirement prediction information, and the charging capacity of the charging device. Furthermore, charging control information for charging the rechargeable batteries according to the optimal charging plan and / or control information for controlling a working device in the operating mode is generated on the basis of the determined device / rechargeable battery combination and the associated optimal charging plan. The invention can be used, for example, in gardening and forestry technology.
