Abstract
An electrically driveable vehicle, in particular a rail vehicle, includes an intermediate DC circuit, an in-vehicle, three-phase on-board electrical system fed by the intermediate DC circuit, at least one drive motor fed by a converter, and at least one coolant pump for pumping a coolant that cools the converter. In addition to the in-vehicle three-phase on-board electrical system, the vehicle also has a second on-board electrical system. The at least one coolant pump is connected to the second on-board electrical system.
Claims13
An electrically drivable vehicle or rail vehicle, comprising:
- at least one intermediate DC circuit;
- an in-vehicle three-phase AC first on-board electrical system fed by said at least one intermediate DC circuit;
- a second on-board electrical system in addition to said in-vehicle three-phase AC first on-board electrical system, said second on-board electrical system being a DC voltage second on-board electrical system;
- a current converter;
- at least one drive motor fed by said current converter;
- at least one coolant pump for pumping a coolant cooling said current converter, said at least one coolant pump being connected to said second on-board electrical system;
- and
- at least one converter;
- said at least one coolant pump being a three-phase AC-operated coolant pump connected through said at least one converter to said DC voltage second on-board electrical system.
