Benefits of technology

The invention provides a better system for controlling the temperature of a motor vehicle's battery. The goal is to keep the battery at a safe level without causing damage.

Problems solved by technology

A disadvantage to such a design is that a fuel-operated heater and an internal combustion engine provide a supply temperature of approximately between 75-85° C. and between 90-110° C. respectively, which, per se, is excessively high for the heating of the battery.
A disadvantage of this design is the relatively complex construction, which requires a heat exchanger for the coupling of the two cooling circuits.

Embodiment Construction

[0038]As illustrated in FIG. 1, embodiments include a first heating / cooling circuit 1 with a heat source 2 arranged therein, and a first pump 3, and a second heating / cooling circuit 4 with a battery 5 to be heated arranged therein and a second pump 6. The first heating circuit 1 and the second heating circuit 4 can be operatively and / or fluidically connected by way of a valve 7 such that the same liquid heat carrier flows through them. Specifically, the valve 7 is designed as a cyclically operated switching valve, whereby the heat exchange between the first and the second heating circuit 1 and 4 can be selectively adjusted. Alternatively, the valve 7 may also be designed as a mixing valve. The first heating circuit 1 further includes a check valve 8 which is arranged between the two connecting lines to the second heating circuit 4, a heat exchanger 10 which is arranged in a passenger compartment 9 of a motor vehicle which includes the arrangement illustrated in FIG. 1, and a compens...

Abstract

A motor vehicle and a method for operating the same. The motor vehicle includes a first heating / cooling circuit with a heat source / sink arranged therein and a first pump, and a second heating / cooling circuit with a battery to be heated / cooled arranged therein and a second pump. The heating / cooling circuits can be selectively operatively and / or fluidically connected by way of at least one valve such that the same liquid heat carrier flows through both heating / cooling circuits.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority under 35 U.S.C. §119 to European Patent Application No. EP 11191472.7 (filed on Dec. 1, 2011), which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The invention relates to a motor vehicle that includes a first heating / cooling circuit having a heat source / sink arranged therein and a first pump, and a second heating / cooling circuit having a battery to be heated / cooled arranged therein and a second pump, and a method for operating such a motor vehicle.BACKGROUND OF THE INVENTION[0003]A heating / cooling circuit for a battery such as, for example, a storage battery of a motor vehicle is known per se. In particular, high-power batteries of electric motor vehicles and hybrid motor vehicles are generally temperature-controlled so as to be operated in a temperature range which is advantageous for power delivery. Therefore, the battery is cooled when outside temperatures are h...
