- the battery 1 comprises a plurality of electrical energy storage modules 2 for supplying electrical energy to an electric motor of the vehicle which may be of the electric type or of the hybrid type , that is to say a vehicle comprising a heat engine in addition to the electric motor.
- Control units 3 called “CMC” for "Cell Monitoring Control” in English are able to transmit information (temperature, charge level, etc.) relating to an operating state of one or more modules electrical energy storage 2. This information is intended to be sent to a general control unit 4 of the battery 1 via a main wiring harness.
- CMC Cell Monitoring Control
- control units 3 can be integrated into modules 2 or externalized with respect to modules 2 for economic reasons.
- control units 3 In the event that they are exteriorized, these control units 3 lose useful space for the installation of the storage modules 2 of electrical energy in a longitudinal direction and / or a transverse direction and / or a vehicle height.
- control units 3 when the control units 3 are arranged on the sides of the motor vehicle as is the case in the configuration shown, they are located in a risk zone in the event of a side impact, known as a “post impact” in the context of the vehicle certifications.
- the invention aims to effectively meet this need by providing a battery comprising:
- At least one control unit capable of transmitting information relating to an operating state of at least one electrical energy storage module
- control unit being placed inside a housing provided in the structural beam.
- the invention thus makes it possible to limit the size of the control unit in order to improve the volume efficiency of the battery.
- walls of the structural beam protect the control unit from external shocks.
- the invention also makes it possible to facilitate the mounting of the control units which are easily accessible for their connection to an electrical harness of the motor vehicle.
- the structuring beam comprises a multi-chamber hollow body.
- the housing of the control unit comprises at least one chamber of the hollow body of the structuring beam, the chamber comprising an opening arranged so as to allow insertion of the control unit inside of said chamber, as well as its withdrawal.
- two closed-volume chambers are arranged on either side of the control unit.
- at least one connector of the control unit intended to be connected to an electrical harness is arranged vis-à-vis the opening.
- control unit is held inside the housing by means of a fixing device.
- the fixing device is a snap-fastening device.
- the structuring beam comprises a through-fastening spacer for the passage of a fastening member making it possible to fix the structuring beam on a structural element of the motor vehicle.
- the subject of the invention is also a motor vehicle characterized in that it comprises a battery as defined above.
- the structuring beam is fixed to a cross member for fixing the seats of the motor vehicle.
- FIG. 1 Figure 1, already described, is a perspective view of a battery according to the state of the art
- Figure 2 is a perspective view of a battery according to the present invention.
- FIG. 3 is a top view showing the housing intended to receive a control unit for one or more electrical energy storage modules;
- Figure 4a is a cross sectional view of a structural beam in an unmachined area
- Figure 4b is a cross-sectional view of a structural beam in a machined area for the integration of a control unit;
- Figure 5 is a longitudinal sectional view of a structural beam illustrating the maintenance of a control unit in its housing by means of a snap-fastening device.
- a longitudinal direction is a direction going from the rear towards the front of the vehicle and corresponding to a direction of longitudinal elongation of the vehicle.
- a transverse direction, parallel to a train of the motor vehicle, is a direction perpendicular to the longitudinal direction and is located in a horizontal plane.
- FIG. 2 shows a battery 10 intended to be arranged outside the passenger compartment of a motor vehicle.
- the battery 10 may be placed in particular under a floor of the motor vehicle.
- the battery 10 can be attached to side members or stretchers of the body of the motor vehicle.
- the battery 10 comprises a plurality of storage modules 1 1 of electrical energy, for example lithium-ion type.
- Control units 12 are able to transmit information (temperature, charge level, etc.) relating to an operating state of one or more storage modules 1 1. This information is intended to be sent to a general control unit of the battery 10 (cf. element referenced 4 in FIG. 1) via a main electrical harness. To this end, each control unit 12 is connected on the one hand to a storage module 1 1 via a first connector 14.1 and on the other hand to the general control unit via a second connector 14.2 connected to an electrical harness from of the main beam.
- the storage modules 1 1 are also connected to a power bus in order to be able to circulate an electric power from the energy storage modules 1 1 to an electric traction machine and vice versa from the electric machine to the modules of storage 1 1 when the electric machine is operating in generator mode.
- the structuring beams 15 In order to stiffen the assembly, the structuring beams 15 have a length extending in the transverse direction of the vehicle. A beam 15 is arranged between storage modules 1 1 adjacent. As a variant, in the case where the orientation of the storage modules 1 1 is changed, the structural beams 15 may have a length extending in the longitudinal direction of the vehicle.
- the structuring beams 15 are preferably made of extruded aluminum in order to limit the weight of the assembly. As a variant, the structuring beams 15 could be made from another metallic material or from a composite material. The structuring beams 15 may belong to a battery box.
- a control unit 12 is arranged inside a housing 16 formed in a structural beam 15.
- a structuring beam 15 comprises a multi-chamber hollow body 17, as shown in FIGS. 4a and 4b.
- the housing 16 of the control unit 12 consists of at least one chamber 19 of the hollow body 17.
- the chamber 19 comprises an opening arranged so as to allow the insertion of the control unit 12 inside said. chamber 19, as well as the removal of the control unit 12 for maintenance in particular.
- the hollow body 17 has seven chambers 19.
- the hollow body 17 may of course include a different number of chambers 19.
- the hollow body 17 has four horizontal walls 21 .1, 21 .2, 21 .3, 21 .4.
- the two upper walls 21 .1 and 21 .2 are machined locally, so that the control unit 12 is placed inside a housing 16 formed by two chambers 19 of the structural beam 15, as can be seen. see in Figures 4b and 5.
- the openings of the two walls 21 .1, 21 .2 are made in vertical coincidence, that is to say that the edges of the opening made in the wall 21 .1 coincide with the edges of the opening made in the wall 21 .2.
- the number of rooms 19 necessary for receiving the control unit 12 can of course be adapted according to the size of the control unit 12 and the size of the rooms 19.
- two closed-volume chambers 19 are arranged on either side of the control unit 12.
- the chambers 19 arranged on either side of the control unit 12 each have, in view in section, their four corners so that the structural beam 15 retains sufficient rigidity enabling it to withstand the shock and torsional forces required in the event of an accident.
- a control unit 12 is held inside the housing 16 by means of a fixing device 22 which advantageously takes the form of a ratchet device.
- the latching device 22 comprises elastically deformable fins 24 each provided with a portion intended to bear against an edge of a horizontal wall of the structuring beam 15 when the control unit 12 is arranged at inside its housing 16.
- the connectors 14.1, 14.2 of the control unit 12 each intended to be connected to an electrical harness 26 are arranged vis-à-vis the opening.
- a structuring beam 15 comprises at least one through fixing spacer 25 for the passage of a fastening member, such as a screw, making it possible to fix the structuring beam 15 on a structural element of the motor vehicle.
- the structuring beam 15 is advantageously fixed to a cross member for fixing the seats of the motor vehicle. Such a configuration makes it possible to stiffen the cross member for fixing the seats.
- the invention thus makes it possible to limit the size of the control unit 12 in order to improve the volume efficiency of the battery.
- the walls of the structural beam 15 make it possible to protect the control unit 12 from external shocks.
- the invention also makes it possible to facilitate the mounting of the control units 12 which are easily accessible for their connection to an electrical harness of the motor vehicle.
- the subject of the invention is also a motor vehicle comprising a battery 10 as defined above.
