Abstract

A charger for a drive battery of a motor vehicle, including a high-voltage electrical outlet configured to charge a drive battery of a motor vehicle, and a thermal portion for generating a coolant for the charger and/or for a battery.

Claims

1-13. -13. (canceled)

14. A charger for a battery for driving a motor vehicle, comprising:

a high-voltage electric outlet configured to charge a battery for driving a motor vehicle; and

a thermal portion for creating a coolant for the charger and/or for a battery.

15. The charger for a battery for driving a motor vehicle as claimed in claim 14, further comprising an outlet configured to communicate with a battery computer.

16. The charger for a battery for driving a motor vehicle as claimed in claim 15, further comprising a low-voltage electric outlet configured to electrically power a battery computer.

17. The charger for a battery for driving a motor vehicle as claimed in claim 14, further comprising a supervisor which manages charging of the battery, diagnostics of the battery, and cooling of the battery.

18. The charger for a battery for driving a motor vehicle as claimed in claim 17, further comprising an Ethernet connector and/or a CAN driver and network connected to the supervisor and configured for its/their connection to an outside.

19. The charger for a battery for driving a motor vehicle as claimed in claim 16, further comprising an electric inlet for powering the charger electrically.

20. The charger for a battery for driving a motor vehicle as claimed in claim 19, further comprising an AC/DC converter connected upstream to the electric inlet and as an outlet to the low-voltage electric outlet.

21. The charger for a battery for driving a motor vehicle as claimed in claim 15, further comprising an I/O board connected to the outlet and configured to communicate with the battery computer by relays that it drives to acquire items of analog information, or to acquire a voltage upstream of the charger and a temperature of outlet air.

22. The charger for a battery for driving a motor vehicle as claimed in claim 14, further comprising a first AC/DC converter which supplies a low voltage at the outlet, a second AC/DC converter which supplies a high voltage at the outlet, and an I/O board, the first and second AC/DC converters being connected to a supervisor which drives the AC/DC converters via an internal bus.

23. The charger for a battery for driving a motor vehicle as claimed in claim 14, wherein the thermal portion for creating a coolant for the charger and/or for the battery comprises a compressor, an air evaporator, a capillary relief valve, and an air condenser for performing a function of a heat pump.

24. The charger for a battery for driving a motor vehicle as claimed in claim 14, in an integrated form in a single casing.

25. The charger for a battery for driving a motor vehicle as claimed in claim 24, wherein the casing comprises some or all of the following components:

a conventional electric power supply;

an Ethernet connector for an Ethernet connection;

a low-voltage electric connector;

a high-voltage electric connector;
