Definitions
- the invention relates to a battery assembly for a motor vehicle, a system comprising such a battery assembly, as well as a motor vehicle comprising such a system.
- the battery cells In order to allow optimum operation, the battery cells must be temperature regulated.
- the battery cells are arranged with a gap between them, which is maintained by spacers.
- These spacers have a mounting portion designed to receive a battery and a wall in the form of a separator blade.
- the spacer thanks to this separating blade, makes it possible to form an air flow path between two battery cells.
- the aim of the invention is in particular to simplify the assembly of a battery assembly.
- the subject of the invention is a battery assembly for a motor vehicle, comprising:
- a holding device comprising a base body, a plurality of spacers and retaining means, each spacer comprising a mounting foot and a separating blade formed in one piece with the mounting foot, the separating blade being disposed in the gap between two adjacent battery cells and configured to separate a first pass of thermal control fluid and a second pass of thermal control fluid, the mounting feet being slidably mounted parallel to the X axis on the base body in at least one row and thus defining a sliding connection between them, the retaining means comprising a first axial stop disposed at a first axial end of the row of battery cells and a second axial abutment disposed at the second axial end of the row of battery cells, the retaining means comprising axial clamping means, which axially compress the second axial abutment against the battery cell located at the second axial end of the row of battery cells, the second axial abutment thus compressing the row of battery cells and the separating blades arranged between them against the first axial abutment
- the assembly is simplified, because the holding device comprises the spacers mounted axially sliding. During axial tightening, the spacers can slide axially so as to avoid any play between each spacer and the adjacent battery cells. By “held tight” it should be understood that there is no axial play between the separator blades and the battery cells. In other words, in an assembled battery assembly, the thermal regulation fluid does not pass between the separator blades and the battery cells.
- the second axial stop is slidably mounted parallel to the X axis on the base body.
- the mounting and positioning of the second axial stop is carried out simply.
- the base body comprises a translation guide rail, the mounting feet being slidably mounted on the translation guide rail.
- the second axial stop comprises a mounting foot slidably mounted on the guide rail in translation.
- the axial clamping means comprise a first axial compression member, which is fixed to the base body and compresses the second axial abutment against the battery cell located at the second axial end of the row of battery cells.
- the axial clamping means comprise a second axial compression member, which compresses the second axial abutment against the battery cell located at the second axial end of the row of battery cells, the second axial compression member and each spacer being connected between them so that their connection is free in translation parallel to the axis X.
- Each spacer has a head formed in one piece with the splitter blade, the head being opposite the mounting foot and being in connection with the second axial compression member.
- each spacer has a guide hole oriented parallel to the X axis, the second axial compression member passing through the guide hole of each spacer.
- the second axial compression member comprises an axial retaining element on the wall of the battery cell opposite the first axial stop.
- the second axial compression member is retained axially directly on the first axial stop.
- the axial compression effect is obtained in a particularly simple manner, and the rigidity of the assembly is improved.
- the first axial thrust bearing is formed in one piece with the basic body.
- the second thrust bearing and the spacers are identical.
- the design and assembly are simplified and the manufacturing costs are reduced, in particular because it is not necessary to design a specific part to form the second axial stop.
- the first axial compression member bears against the mounting foot of the second axial stop.
- an axial compressive force can be applied without blocking the axial thermal expansion of the battery cells.
- Each spacer comprises a thermal regulation fluid passage, disposed in the splitter blade at the end opposite the mounting foot, and allowing the passage of thermal regulation fluid between the first pass and the second pass.
- the thermal control fluid passage is a thermal control fluid passage hole.
- the mounting feet comprise, at their axial ends forming axial clearance between them, a complementary shape forming a baffle between them for the thermal regulation fluid.
- the baffle comprises a longitudinal portion extending parallel to the axis X.
- a longitudinal portion not only makes it possible to guarantee the sliding of the spacers between them, but also to ensure that the clearance created between the mounting feet during of the assembly with the battery cells does not increase the minimum passage section of the baffle, through which the thermal regulation fluid passes, beyond a threshold predefined by the longitudinal portion. Therefore, leakage of thermal control fluid out of the desired flow path between the first pass and the second pass is limited.
- the base body comprises at least one thermal regulation fluid passage hole, which is surmounted by a fan.
- the base body is made of plastic material, preferably of thermoplastic material, more preferably of polypropylene. Thus, the manufacture of the base body is easy and inexpensive.
- the spacers are made of plastic material, preferably of thermoplastic material, more preferably of polypropylene or thermoplastic polyurethane. Thus, the manufacture of the spacers is easy and inexpensive.
- the thermal regulation fluid is gaseous, preferably the thermal regulation fluid is air.
- the thermal regulation fluid is air.
- Another subject of the invention is a system comprising a battery assembly as defined previously and a casing, which contains the battery assembly, the thermal regulation fluid circulating in a closed circuit in the casing.
- the thermal regulation fluid circuit is closed, the entry of external elements into the thermal regulation fluid circuit, such as for example dust or humidity, is avoided, which increases the duration of system life.
- the box is sealed against the thermal regulation fluid. Thus, leakage of thermal control fluid outside the housing is avoided.
- the housing is sealed against humidity and dust, for example airtight.
- humidity and dust for example airtight.
- the thermal control fluid circulates along a flow path passing through a fan, a heat exchanger, the first pass, and the second pass.
- the flow path is optimized.
- the subject of the invention is a motor vehicle comprising a system as defined above.
