Abstract: A device capable of processing a pilot control signal having at least two modes: continuous or alternating PWM, and of generating a binary detection signal, the state of which is an indication of the mode, the device having a voltage doubler and a comparator.

Abstract: Disclosed is a device for controlling a connection between an electrical socket and a battery. The device for controlling a connection includes a first contactor arranged between a first terminal of the battery and a first terminal of the electrical socket, a second contactor arranged between a second terminal of the battery and a second terminal of the electrical socket, a first computer and a second computer. The first computer includes a high-side switch, arranged between a power supply line and the first contactor, and a low-side switch arranged between the second contactor and a ground line, and the second computer includes a low-side switch arranged between the first contactor and the ground line, and a high-side switch arranged between the power supply line and the second contactor.

Abstract: The invention relates to a method of diagnosis of a state of end of life of a determined type of battery such as a cell, in particular a lithium/manganese cell. According to this method, during the use of a battery of the determined type within the framework of a given application, periodic measurements are performed of the voltage across the terminals of the battery and of the corresponding ambient temperature, each measured value of the voltage across the terminals of the battery is compared with corresponding values previously stored during a specific preliminary calibration phase, a counting is established of the number of measured values below the corresponding values measured, and an alert signal warning that the end of the life of the battery is delivered after counting of a number n of measured values below the corresponding values stored.

Abstract: The invention relates to a method and a device for controlling the life of a battery (5) such as a cell, particularly a lithium/manganese cell. According to the method of the invention, a voltage raiser electrically supplied by the battery and adapted to make up for any deficiencies of the latter is used, an indicator parameter of the operation of the battery is selected, and a threshold value of said indicator parameter, below which said battery is considered to be incapable of having a satisfactory performance, is fixed and stored, the indicator parameter is then measured periodically, and the supply to the voltage raiser is triggered if, and only if, the measured value of said indicator parameter becomes lower than the stored threshold value.
