Abstract
A method for determining information (Info) about a state (Z) of a drive motor system () and/or of a drive battery pack () of a gardening, forestry and/or construction device (), includes the steps of: acquiring at least one sensor temperature (TS) of at least one temperature component () of the drive motor system () and/or of the drive battery pack () by way of at least one component temperature sensor () at the same time as and/or at a time after operation of the drive motor system () and/or of the drive battery pack () and/or of a heater () and/or of a cooler () and/or of a fan () for heating and/or for cooling the drive battery pack (), wherein the temperature component () heats up or cools down due to the operation; ascertaining operating data (BD) of the operation, wherein the operating data (BD) are of a different kind than the sensor temperature (TS); comparing the acquired sensor temperature (TS) or a variable based on the sensor temperature and the ascertained operating data (BD) or a variable (TM) based on the operating data (BD) by way of a temperature model (MOD), wherein the temperature model (MOD) is based on at least one model state (AZyes) of the drive motor system () and/or of the drive battery pack (); and determining the information (Info) on the basis of a result of the comparison.
