Abstract: A method of controlling charge of a battery, or of a battery of a motor vehicle, on the basis of a monophase network, in which: the input voltage is filtered; the electrical power of the network is conveyed to the battery via a voltage step-down stage and a voltage step-up stage which are coupled together via an inductive component; and an intensity of current passing through the inductive component is controlled as a function of an intensity setpoint, the intensity not being continuously controllable. The intensity setpoint is formulated to have at least a first value and at least a second value greater than the first value, the intensity setpoint having the second value before the start of a phase during which the intensity is not controllable.

Abstract: A device synchronizes primary speed of a primary shaft receiving an electrical torque from an electric machine with a secondary speed lower than the primary speed of a secondary transmission shaft. The primary shaft and secondary shaft are decoupled. The primary shaft has a kinetic energy associated with the primary speed. The device provides electrical braking torque to the primary shaft until the primary speed is substantially equal to the secondary speed. The device also at least partially recovers, in the form of electrical energy, the kinetic energy lost by the primary shaft and transmits the electrical energy to an energy storage device.

Abstract: A method for estimating an insulation resistance between a point of a high-voltage circuit including a high-voltage motor vehicle battery and a ground of the vehicle includes measuring a voltage value at terminals of a measurement circuit that includes a capacitive element connected to the battery and calculating a standard deviation value based on the measured voltage value and based on a theoretical voltage value estimated from a model of the measurement circuit. The model is a function of a capacitance value of the capacitive element. The method also includes calculating an averaged deviation value from the standard deviation value and previous deviation values and estimating an updated insulation resistance value in accordance with the averaged deviation value.
