<p>The device (10) has an input (11) connected to an electrical energy generator i.e. photovoltaic generator (12), and a storage unit for storing electrical energy generated by the generator. A voltage and/or current regulator manages the electrical energy. Another storage unit (13) is formed by a rechargeable battery (13A) e.g. lithium button battery, with low leakage current. A management and control unit formed of a processing circuit (17) and a switch (18) manages and controls charge of the latter storage unit for limiting depth of discharge of the battery. Independent claims are also included for the following: (1) a sensor assembly, comprising a processing circuit and power supply device (2) a method of supplying power to a wireless communication system.</p> |
