Abstract

A method for mounting or removing a power supply container of a drive motor of a motor vehicle that is secured to the motor vehicle using a bolt acted on by a piston. The method includes: acting on the piston to move the pistons relative to the bolt so as to disengage the bolt; and rotating the bolt such as to lock or unlock the bolt and lock or unlock the battery.

Claims

1-11. -11. (canceled)

12. A method for mounting or removing a container of energy that powers an engine or motor that propels a motor vehicle, fixed to the motor vehicle using a lock on which a piston acts, the method comprising:

(a) acting on the piston to cause the piston to move in relation to the lock to disengage the lock; and

(b) turning the lock to lock or unlock the lock and lock or unlock a battery.

13. The method for mounting or removing a power supply energy container as claimed in claim 12, wherein the (a) acting comprises pushing the piston to move the piston translationally against an elastic means.

14. The method for mounting or removing a power supply energy container as claimed in claim 12, wherein the (b) turning comprises rotating the lock by half a turn or less.

15. The method for mounting or removing a power supply energy container as claimed in claim 14, wherein the (b) turning is obtained by associating a connecting means of a tool with a connecting means of one end of the lock.

16. The method for mounting or removing a power supply energy container as claimed in claim 12, further comprising fixing a tool for implementing the method to at least one corresponding element of the vehicle body shell, of the battery or of the lock, prior to the (a) acting.

17. The method for mounting or removing a power supply energy container as claimed in claim 16, wherein the fixing a tool includes connecting the tool via at least two connecting elements that are distributed symmetrically about a connecting means of the lock.

18. The method for mounting or removing a power supply energy container as claimed in claim 16, wherein the fixing a tool includes inserting a mushroom-shaped element into a corresponding slot.

19. The method for mounting or removing a power supply energy container as claimed in claim 12, wherein the (a) acting and the (b) turning are performed automatically using a motorized tool.

20. A method for replacing a container of energy that powers an engine or motor that propels a motor vehicle, comprising:

a method for mounting or removing the power supply energy container as claimed in claim 12.

21. A system for mounting or removing a container of energy that powers an engine or motor that propels a motor vehicle, comprising:

hardware and/or software means for implementing the mounting or removal method as claimed in claim 12.

22. A station for mounting or removing a container of energy that powers an engine or motor that propels a motor vehicle, comprising a mounting or removal system as claimed in claim 21.
