1. A stator for a rotary electrical machine which is designed to equip a vehicle, the stator comprising:
an annular body around an axis; and
a winding,
the annular body comprising a plurality of notches distributed circumferentially regularly around the annular body, and
the winding comprising a first series of conductive pins and a second series of conductive pins arranged in the notches in a plurality of superimposed layers of the winding in a radial direction, i.e. at least a first layer, a second layer, a third layer and a fourth layer which succeed one another, such that the first layer is radially on the exterior and the fourth layer is radially in the interior, with each conductive pin comprising a first segment and a second segment which are connected by an elbow connection, such that the segments of a single conductive pin are disposed in distinct notches,
wherein the first segments and the second segments of the first series of pins are arranged respectively in the first layer of the winding and in the second layer of the winding, and the first segments and the second segments of the second series of pins are arranged respectively in the third layer of the winding and in the fourth layer of the winding,
wherein the first series of pins is connected electrically to the second series of pins,
wherein an electrical connection element comprises a first conductor and a second conductor which are partly disposed in distinct notches, with the first conductor occupying one of the layers which are common to the first series of pins, and the second conductor occupying one of the layers which are common to the second series of pins,
wherein the first conductor and the second conductor being connected electrically to one another, the first conductor and the second conductor occupying two distinct layers of the winding, and being separated from one another by at least one layer, and
wherein the first series of pins is connected electrically in series by the electrical connection element to the second series of pins.
