Energy expenditure device and method for issuing a remaining possibility of use

摘要

The present invention relates to an energy consumption output device for outputting the remaining possibility of use of an electrical load (16) connectable to an energy store (12), the energy consumption output device comprising: - a unit (15) for providing a residual capacity of the electrical energy store (12); - A power consumption determination unit (14) which is designed to determine a power consumption rate in a current operating mode of the electrical load (16); and - an output unit (18) configured to determine information about the maximum usage possibility to the user of the power consumption output device using the provided remaining capacity and the determined power consumption rate with respect to the current operation mode, and to output this information.
