Abstract
The power supply control module is designed to be associated with a power supply battery (1) for powering an appliance (2). The control module includes a detector circuit (4) associated with a switch circuit (5) placed in the loop via which the battery powers the appliance, the detector circuit including a shunt resistor (9) which is inserted between the battery and the switch circuit, and two operational amplifiers (7, 8) connected as comparators, one of the amplifiers being active when the battery is being used as a power source, and the other amplifier being active during fast battery-charging. The second amplifier (8) is also connected to the terminals of a diode (19) in parallel with the switch circuit, so that the amplifier is active during trickle battery-charging. The battery preferably includes a power supply control module housed inside the pack in which it is packaged.
