The invention relates to a method of operating a drive apparatus (1) in a window screening kit (2) such as a blind, venetian blind, awning or roller shutter for a window (3), said method comprising the steps of:
powering an electrical motor (4) in said drive apparatus (1) from a power supply unit (6) for driving a moveable part (5) of the window screening kit (2) between positions wherein said power supply unit (6) includes a battery storage (7) for energy storing and powering said electrical motor (4), at least one solar power cell (8) for powering said electrical motor (4) and/or said battery storage (7) and a regulator unit (9),
detecting state of charge (SOC) such as voltage values of said battery storage (7) and detecting a temperature values in or at said battery storage (7) with at least voltage and temperature detectors (10),
comparing said detected voltage and temperature values in said regulator unit (9) with predefined threshold values (Tthr, Vthr) of voltage and temperature for said battery storage (7), and
regulating the powering of said battery storage (7) with said regulator unit (9) in response to the comparison of values. Moreover, the invention relates to a drive apparatus (1) for a window screening kit (2) and a window screening kit (2). |
