    Abstract: The present invention relates to a solid-state relay including a power semiconductor switch device connected between a first electrical terminal and a second electrical terminal and having a command terminal. An electronic driving block is adapted to generate a command signal applied to the command terminal to switch the at least one semiconductor switch device from a closed/open state to an open/closed state to disconnect/connect the first electrical circuit portion from/to the second portion of the electrical circuit. An electronic block detects a current which crosses the power semiconductor switch device. The electronic detection block includes a first electronic device adapted to generate a first signal indicative of a difference of potential between the first and second terminals generated by the current which crosses a total resistance present between the first and second terminals of the power semiconductor switch device in the closed state. The total resistance comprises the sum of a first resistance associated with the semiconductor switch device in the closed state and of second bonding resistances associated with an electrical connection between one of the conductive terminals and the respective either first or second electrical terminal.

    Abstract: An electronic device including an electronic switch M1, an electrical pre-charge circuit and a measurement, command and diagnosis module. The main electronic switch M1 has a first electrical terminal D1, a second electrical terminal S1, and a main driving terminal G1. The main electronic switch M1 is adapted to take, based on a driving signal DRV, depending on the command signal CMD and on an enabling signal ENB, a closed condition or an open condition, wherein the first electrical terminal D1 is respectively connected to or disconnected from the second electrical terminal S1. The pre-charge electrical circuit is adapted to carry out, based on the command signal CMD, a pre-charge operation, aimed at equalizing the electric potentials (V1, V2) of the first and second terminals of the device, before the main electronic switch M1 takes a closed condition, upon of a transition from the open condition.

    Abstract: A method for estimating an operating current I dispensed by a battery pack or cell including the steps of acquiring characterization data of the battery pack or cell, related to measured time trends of a voltage Vm and of a characterization current Im of the battery pack or cell, associated with a respective characterization temperature value Tk; and then processing the characterization data to determine a plurality of parameters P of a model of the battery pack or cell, as a function of temperature and state of charge SOC. Measuring an operating voltage V of the battery pack or cell and an operating temperature T and for estimating the operating current I of the battery pack or cell. A plurality of time observation windows Wi is identified and characterization voltage Vmi values are detected. Then, at each observation window Wi, the following actions are performed: calculating a value of the state of charge SOCi of the battery pack or cell; calculating an estimated voltage VABi, by means of the model of the battery pack or cell, as a function of respective nominal values of the parameters P; determining a respective error function Ei dependent on the difference between the estimated voltage VABi and the characterization voltage Vmi of the time observation window Wi; calculating an actual value Pi for each parameter P, by minimizing the aforesaid error function Ei.
