Abstract

A method for managing a battery used to drive a motor vehicle. The method includes: storing data relating to the battery, as a function of time, during certain use phases of the motor vehicle; and transmitting battery-related data stored in a memory unit of a central server during a charging phase of the battery in a battery management station.

Claims

1-10. -10. (canceled)

11. A method for managing a battery for driving a motor vehicle, comprising:

storing, as a function of time, data relating to the battery during certain phases of use of the motor vehicle, the data comprising a temperature and a state of charge of the battery and an identifier of the battery and/or of a supplier of each battery and/or a location of the battery;

transmitting the battery-related data stored in a memory of a central server during a battery charging phase in a battery-management station;

storing over time the temperature and the state of charge of the battery during a running phase of the motor vehicle;

storing over time the temperature and the state of charge of the battery when the motor vehicle is parked; and

storing over time data representing a history of charging phases of the battery.

12. The method for managing a battery as claimed in claim 11, further comprising a periodic activation of the motor vehicle when parked to carry out the storing of the temperature and the state of charge of its battery.

16. A method for managing a stock of batteries for driving motor vehicles, using the method for managing each battery of the stock as claimed in claim 11.

17. A non-transitory data-recording medium that can be read by a computer on which is recorded a computer program comprising computer-program code means for implementing the method as claimed in claim 11.

18. A device for managing a battery for driving a motor vehicle, comprising:

a means of connection to a memory comprising data relating to the battery of a motor vehicle;

a means of transmitting data to the memory of a central server; and

a means of implementing a method for managing a battery as claimed in claim 11.

19. The device for managing a battery as claimed in claim 17, wherein the means for transmitting data to the memory of a central server comprises at least one fieldbus for a first transmission to a supervision unit of a battery-management station, then a digital network of internet type for a second transmission to the memory of the central server.

20. The device for managing a battery as claimed in claim 18, comprising plural battery chargers associated with a fieldbus of the CAN bus type for a transmission of data from a memory associated with a battery to a battery charger, and a link by fieldbus from each charger to a supervision unit of a management station.
