Abstract

Vehicle battery box (1) comprising at least one outer casing (2) delimiting a chamber (3) receiving the battery (9) and comprising a support (4) and a removable cover (5) connected to each other, the box (1) comprising positioning lugs (15, 16) and lugs (17, 18) for fixing said battery box (1) to the vehicle, said positioning lugs (15, 16) and said fixing lugs (17, 18) being mounted on the outer casing (2). Each positioning lug (15, 16) comprises a passage (19c, 20c) receiving a positioning stud (37).

Claims

1. A 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, wherein each positioning lug comprises a passage receiving a positioning stud.

2. The batter box according to claim 1, comprising two positioning lugs.

3. The battery box according to claim 1, wherein the positioning stud has a threaded end and a conical end, the conical end being adapted to be inserted in the receiving passage.

4. The battery box according to claim 1, wherein each positioning lug comprises two L-shaped brackets connected to each other, said brackets being fixed to the outer casing of the battery box.

5. The battery box according to claim 1, comprising a second outer casing delimiting a second battery receiving chamber and comprising a cover placed over the first cover.

6. The battery box according to claim 5, wherein one of said positioning lugs comprises two supplementary brackets connected to two first brackets, said supplementary brackets being mounted on the second outer casing.

7. The battery box according to claim 1, comprising internal partitions delimiting compartments in said receiving chamber, said compartments being adapted to receive energy storage cell units.

8. The battery box according to claim 1, comprising at least one exterior recess for receiving a removable member of an isolator connected to the battery.

9. A method of mounting a battery box on a vehicle, said battery box comprising at least one outer casing delimiting a chamber receiving the battery, wherein the method comprises the steps of:

screwing positioning studs to the vehicle;

placing the battery box on the vehicle so that the positioning studs are inserted in positioning lugs provided on said battery box; and

fixing the battery box to the vehicle with fixing lugs provided on the battery box.

10. The mounting method according claim 9, wherein two positioning studs are screwed to the vehicle.

11. The mounting method according to claim 9, wherein the vehicle is lowered and/or the battery box is raised to carry out the positioning step.

12. The mounting method according to claim 9, wherein, when positioning the battery box, the positioning lugs are guided by conical ends of the positioning studs.

13. The mounting method according to claim 9, wherein the fixing lugs are fixed to the vehicle with bolts.

14. The mounting method according to claim 9, wherein, before manipulating the battery box, a removable member if separated from an isolator connected to the battery to isolate the battery box from an electronic device for management of said battery box.
