Abstract

The invention relates to a method for replacing an energy container supplying power to a driving engine of an automobile resting on the ground and including a longitudinal axis, a transverse axis and a vertical axis, the replacement method including a first step of positioning the automobile relative to the ground without any action from the driving engine of the automobile, characterised in that said method includes a step of releasing the linking restraints linking the energy container to the automobile.

Claims

1. A method for replacing a container (20;

42) of energy for powering a motor for driving a motor vehicle (11;

41) resting on a floor and comprising a longitudinal axis (X), a transverse axis (Y) and a vertical axis (Z), the replacement method comprising a first step of positioning the motor vehicle relative to the floor (80) in the absence of action of a motor for driving the motor vehicle, which replacement method being characterized in that it comprises a step of withdrawing the constraining linkage elements linking the energy container to the motor vehicle.

2. The replacement method as claimed in the preceding claim, characterized in that said step of withdrawing the constraining linkage elements comprises a locking of means (29) for absorbing vertical forces applied to the energy container and bringing a pallet (25;

51) into contact with the energy container, said pallet (25;

51) being previously positioned under the energy container of the motor vehicle.

3. The replacement method as claimed in the preceding claim, characterized in that said locking of means for absorbing vertical forces comprises the rotation of a removable element (29), capable of absorbing the vertical forces exerted by actuators (27, 28), so that the attitude of the motor vehicle is not modified.

4. The replacement method as claimed in one of the preceding claims, characterized in that the first positioning step comprises:

positioning the motor vehicle relative to the floor along the longitudinal axis, and/or

positioning the motor vehicle relative to the floor about the vertical axis.

5. The replacement method as claimed in one of the preceding claims, characterized in that it comprises a second step of positioning a system (10;

40) for replacing an energy container for powering a motor for driving a motor vehicle relative to the motor vehicle.

6. The replacement method as claimed in claim 5, characterized in that the second positioning step comprises:

positioning the replacement system relative to the motor vehicle along the transverse axis.

7. The replacement method as claimed in one of the preceding claims, characterized in that it comprises a third step of precise positioning of the motor vehicle relative to the floor in the absence of action of a motor for driving the motor vehicle.

8. The replacement method as claimed in claim 7, characterized in that the third positioning step comprises:

positioning the motor vehicle relative to the floor along the longitudinal axis, and/or

positioning the motor vehicle relative to the floor about the vertical axis,

by interaction of positioning means (23, 24;

43, 44, 47, 48).

9. The replacement method as claimed in one of the preceding claims, characterized in that it comprises a fourth step of positioning the body of the motor vehicle relative to the floor.

10. The replacement method as claimed in claim 9, characterized in that the fourth positioning step comprises:

positioning the body of the motor vehicle relative to the floor along the vertical axis, and/or

positioning the body of the motor vehicle relative to the floor about the longitudinal axis, and/or

positioning the body of the motor vehicle relative to the floor about the transverse axis.

11. The replacement method as claimed in one of the preceding claims, characterized in that it comprises a fifth step of the energy container being taken over by the replacement system.

12. The replacement method as claimed in the preceding claim, characterized in that said step of withdrawing the constraining linkage elements is carried out after said fifth step of the energy container being taken over by the replacement system.

13. A system (10;

40) for replacing an energy container (20;

42) for powering a motor for driving a motor vehicle (11;

41), characterized in that it comprises hardware means (17, 18, 31, 32, 22, 25, 26, 27, 28, 29;

17, 18, 31, 45, 46, 51) and/or software means for applying the replacement method as claimed in one of the preceding claims.

14. A station for replacing an energy container for powering a motor for driving a motor vehicle, characterized in that it comprises a replacement system as claimed in one of the preceding claims.
