Method For Controlling The Battery Capacity Of A Secondary Battery And Battery-Driven Household Electrical Appliance

A method for controlling the battery capacity of a secondary battery in a battery-driven household electrical appliance wherein the battery-driven household electrical appliance has an electrical load and a control means adapted to control the operation of the household electrical appliance and to monitor the capacity of the secondary battery, said method comprising the following steps:

• recognizing a situation of storage of the household electrical appliance in which the household electrical appliance is not in use;
• determining the current capacity of the secondary battery;
• comparing the current capacity of the secondary battery with a desired storage capacity for the electrical household appliance;
• activating an energy-consuming load in the electrical household appliance if the current capacity of the secondary battery is higher than the desired storage capacity until the current capacity is equal to the desired storage capacity;
• activating an energy saving stand-by mode of the household electrical appliance until the household electrical appliance is used the next time,
• wherein activation of the energy-consuming load comprises the activation of a microcontroller of the control means into an operational modus.
