The invention also relates to a facility comprising the vehicle ( 100 ) and at least one station ( 200 ) for recharging the vehicle.

First claim

The invention claimed is:

1. An electric vehicle, comprising an electric motor and energy storage means onboard, electrically connected to the electric motor, in order to supply electric energy to said electric motor, wherein the energy storage means comprise:
a first energy storage module comprising at least one supercapacitor,
a second energy storage module comprising at least one battery,
the first energy storage module and the second energy storage modules being laid out on parallel electrical branches, the vehicle comprising interconnection means, which are connected to the electric motor, to the first energy storage module and to the second energy storage module,
wherein the interconnection means are positioned between the energy storage modules and the electric motor, wherein the interconnection means comprise a switch configured for having a first position connecting the first energy storage module to the electric motor and a second position connecting the second energy storage module to the electric motor,
wherein the switch is configured so as not to allow both connections of the first energy storage module and of the second energy storage module to the electric motor,
wherein the vehicle comprises:
first connection means, capable of connecting the first storage module to additional connection means, located outside the vehicle,
second connection means, which are distinct from the first connection means and which are capable of connecting the second energy storage module to additional connection means, located outside the vehicle.

2. The vehicle according to claim 1 , at least comprising a DC/DC converter interposed between the second connection means and the second energy storage module.

3. The vehicle according to claim 1 , comprising means for controlling the interconnection means, capable of controlling the interconnection means according to one or several of the following parameters:
parameters related to the operation of the first and/or the second energy storage module,
parameters related to the operation of the vehicle,
a signal from a user interface.

4. The vehicle according to claim 3 , wherein the means for controlling the interconnection means are able to communicate with one or several of the following elements:
means for monitoring the first storage module,
means for monitoring the second storage module,
means for monitoring the other units of the vehicle.

5. The vehicle according to claim 1 , comprising a DC/DC converter, interposed between the electric motor and at least one of the energy storage modules.

6. The vehicle according to claim 5 , wherein said DC/DC converters operates as a variable speed drive, the vehicle also comprising means for controlling the variable speed drive, controlling the variable speed drive according to at least one parameter from the following list:
parameters related to the operation of the first and/or the second energy storage module,
parameters related to the operation of the vehicle,
a signal from a user interface.

7. The vehicle according to claim 6 , wherein the means for controlling the variable speed drive are able to communicate with one or several of the following elements:
the means for monitoring the first energy storage module,
the means for monitoring the second energy storage module,
the means for monitoring the other units of the vehicle.

8. The vehicle according to claim 1 , wherein the energy storage means are positioned in a roof box of the vehicle.

9. A transport facility, comprising:
at least one vehicle according to any one of claims 1 or 2 - 8 , and
at least one station for recharging the vehicle positioned on a path of the vehicle and in the vicinity of which the vehicle is intended to stop, the station being connected to at least one energy source and including connection means, so-called third connection means mating the first connection means of the vehicle, and capable of electrically connecting said or one of the energy sources to the first energy storage module.

10. The facility according to claim 9 , wherein the first connection means of the vehicle comprise an arm, which is telescopic and able to extend by protruding from the vehicle and comprising a connector at its end, the third connection means comprising a connector mating the one located at the end of the arm and positioned at the station so that both connectors of the vehicle and of the station may come into contact.

11. The facility according to claim 9 , wherein said or at least one of the stations comprises energy storage means comprising at least one third storage module comprising one or several supercapacitors electrically connected to said or at least one of the energy sources on the one hand and to the third connection means on the other hand.

12. The facility according to claim 9 , wherein said or at least one of the stations comprises at least one DC/DC converter interposed between the third storage module and the third connection means.

13. The facility according to claim 9 , wherein said or at least one of the stations is electrically connected to an urban electricity distribution network forming said or one of the energy sources, and comprises an AC/DC converter interposed between the network and the third connection means.

14. The facility according to claim 9 , wherein said or at least one of the stations comprises fourth connection means, distinct from the third connection means and mating the second connection means of the vehicle connected to the second energy storage module of the vehicle, capable of connecting said or one of the energy sources to the second energy storage module.

15. The facility according to claim 9 , wherein said or at least one of the stations is connected to an autonomous energy source.

16. The facility according to claim 15 , wherein said station(s) also comprise(s) a fourth storage module including at least one battery electrically connected to the autonomous energy source in order to store the energy from this source.

17. The vehicle according to claim 1 , at least comprising an AC/DC converter interposed between the second connection means and the second energy storage module.
