摘要： An electronic control device for controlling a vehicle battery pack comprises a non-programmable monitoring and actuation unit and a two-way serial communication interface. The non-programmable monitoring and actuation unit is electrically and operatively connectable to the battery pack and to each of the battery cells C to detect analog battery parameters P, including at least the magnitudes of battery voltage Vb and battery current Ib, in addition to temperature (Tc1, Tcn), current (Ic1, Icn) and voltage (Vc1, Vcn) of each battery cell C. The non-programmable monitoring and actuation unit generates monitoring signals Sm representative of the detected analog battery parameters P. The two-way serial communication interface is connected to the non-programmable monitoring and actuation unit to receive the monitoring signals Sm and to supply the aforesaid at least one command signal Sc.

摘要： A cooling circuit with cooling liquid for lithium-ion batteries comprising a battery pack comprising a plurality of cells electrically connected with each other, suitable for powering an electric machine for traction. The cells are perimetrically delimited by external walls. At least one bag contains cooling liquid associated in contact with the outer walls of the cells. The bag is made of deformable plastic material so as to be counter-shaped to the outer walls to adhere perimetrally to the outer walls and the circuit provides forced circulation of the cooling liquid through said at least one bag.

摘要： 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.

摘要： 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.

摘要： An electronic device for the diagnosis of insulation loss of an energized electrical apparatus, with respect to a ground. The device includes a first resistance-switch group and a second resistance-switch group, connectable or disconnectable in a controlled manner, and also a first measurement circuit and a second measurement circuit, arranged in parallel to the first and second resistance-switch groups, respectively. The first and second measurement circuits include respective first and second detection circuits, first and second charge modulation circuits and first and second partition resistors (RBminus, RBplus). The first and second charge modulation circuits allow a dynamic “switching” measurement technique. Moreover, a method is described for measuring the insulation resistances (RIminus, RIplus) of an energized electrical apparatus with respect to ground, in which the method is carried out by a device according to the invention. Finally, a self-diagnosis method of device is described.
