Method for Determining Information About a State of a Drive Motor System And/or of a Drive Battery Pack of a Gardening, Forestry And/or Construction Device, and System for Determining Information About a State of a Drive Motor System And/or of a Drive Battery Pack of a Gardening, Forestry And/or Construction Device

摘要

A method for determining information (Info) about a state (Z) of a drive motor system (2) and/or of a drive battery pack (11) of a gardening, forestry and/or construction device (1), includes the steps of: acquiring at least one sensor temperature (TS) of at least one temperature component (3) of the drive motor system (2) and/or of the drive battery pack (11) by way of at least one component temperature sensor (4) at the same time as and/or at a time after operation of the drive motor system (2) and/or of the drive battery pack (11) and/or of a heater (300) and/or of a cooler (310) and/or of a fan (320) for heating and/or for cooling the drive battery pack (11), wherein the temperature component (3) 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 (2) and/or of the drive battery pack (11); and determining the information (Info) on the basis of a result of the comparison.
