Abstract

A vehicle has an electric drive, at least one energy accumulator for supplying the electric drive with electric energy, and at least one current collector for charging the energy accumulator with electric energy from a stationary power network. The current collector is connected to the energy accumulator via at least one charge rectifier for the controlled charging of the energy accumulator. The vehicle includes a central cooling system and at least one closed cooling circuit with liquid coolant in order to cool the energy accumulator and the charge rectifier.

First claim

1 - 11 . (canceled)

12 . A vehicle, comprising:
at least one electric drive; at least one energy accumulator for supplying said electric drive with energy; at least one current collector for charging said energy accumulator with electrical energy from a stationary power network; at least one charge converter connected between said current collector and said energy accumulator for controlled charging of said energy accumulator; and a central cooling system and at least one closed cooling circuit with liquid coolant configured to cool said energy accumulator and said charge converter.

13 . The vehicle according to claim 12 , wherein said cooling circuit comprises at least one heat exchanger for said energy accumulator and at least one heat exchanger for said charge converter, wherein said heat exchanger for said charge converter is arranged before said heat exchanger of said energy accumulator, starting from said central cooling system.

14 . The vehicle according to claim 13 , wherein said cooling circuit comprises a first cooling circuit and a different, second cooling circuit each with liquid coolant and different from one another, wherein said at least one heat exchanger for said energy accumulator is arranged in said first cooling circuit, and wherein said at least one heat exchanger for said charge converter is arranged in said second cooling circuit.

15 . The vehicle according to claim 13 , which comprises at least one valve configured to control a coolant flow through at least one heat exchanger, said at least one valve being arranged in said cooling circuit before said at least one heat exchanger in a liquid flow from said central cooling system.

16 . The vehicle according to claim 13 , wherein one or both of the following are true:
said at least one heat exchanger is one of a plurality of heat exchangers for said at least one charge converter; and said at least one heat exchanger is one of a plurality of heat exchangers for said at least one energy accumulator.

17 . The vehicle according to claim 12 , which further comprises at least one on-board network converter and at least one heat exchanger in said cooling circuit for cooling said on-board network converter.

18 . The vehicle according to claim 17 , wherein said heat exchanger of said on-board network converter is identical to a heat exchanger of said charge converter.

19 . The vehicle according to claim 12 , which comprises a heating element for heating the liquid coolant in said at least one cooling circuit.

20 . The vehicle according to claim 12 , wherein said central cooling system comprises at least one condenser, at least one compressor, and at least one evaporator.

21 . The vehicle according to claim 12 , wherein said central cooling system and said at least one charge converter are arranged in a common device container of the vehicle.

22 . The vehicle according to claim 12 , which comprises at least one passive, inductive power component arranged in an airflow after a condenser of said central cooling system, starting from a fan of said central cooling system.
