The accumulator assembly comprises a plurality of electrical energy accumulator elementssuperimposed along a stacking axis, each element comprising connecting electrodes, spacerspositioned axially between at least some of said connecting electrodes, and assembly barsextending axially through the apertures in the connecting electrodes and in the spacers. The assembly further comprises end plateswhich interact with the assembly bars to clamp the connecting electrodes and the spacers axially, and resilient prestressing meanswhich interact with at least one of the end plates to exert axial prestressing forces on the stacked connecting electrodes and spacers.

Battery unit for an electric or hybrid vehicle

A device for connectionof a batteryto an electric or hybrid motor vehicle, comprising at least one inputcapable of being connected to a first terminalof the battery and at least one outputcapable of being connected to a first terminal of an electrical circuit of the vehicle. The devicealso comprises: a device for measuring the voltagebetween the first terminalof the battery and a reference potential, and a control unitcapable of receiving the voltage values measured by the voltage-measuring device, capable of determining an insulation resistance between the first terminalof the battery and the reference potential, and capable of connecting or keeping connected the first terminalof the battery and the first terminal of the electrical circuit if said insulation resistance is greater than a determined threshold.

Connection device comprising a control unit, battery case comprising such a connection device and method for controlling such a battery case

An accumulator assembly comprising a plurality of electrical energy accumulator elements () superposed on a stacking axis and each comprising connecting electrodes (), wherein it comprises at least one electrically conductive spacer () arranged axially between the connecting electrodes of two adjacent accumulator elements and electrically linked to at least one of said elements, and at least one connecting plug () mounted inside a void () of the conductive spacer and linked to an electric cable () for a voltage measurement.

Accumulator assembly for a battery of an electric or hybrid vehicle, provided with a connecting strut

Vehicle battery box () comprising at least one outer casing () delimiting a chamber () receiving the battery () and comprising a support () and a removable cover () connected to each other, the box () comprising positioning lugs () and lugs () for fixing said battery box () to the vehicle, said positioning lugs () and said fixing lugs () being mounted on the outer casing (). Each positioning lug () comprises a passage () receiving a positioning stud ().

Battery box for electric or hybrid vehicle and method for mounting said box on the vehicle

The accumulator assembly comprises a plurality of electrical energy accumulator elementseach comprising connecting electrodes, assembly meanslinking said electrodes, a connectorfor connecting an external component to the assembly, and a connector support. The supportcomprises a mounting baseborne by the assembly means and a fixing lugsupporting the connector and configured in such a way as to allow a movement of the connector relative to the mounting base in response to an external stress exerted on said connector and/or on the fixing lug.
