Embodiment Construction

[0032] figure 1 Shown is a first heating circuit 1 with a heat source 2 arranged therein and a first pump 3 , and a second heating circuit 4 with a battery 5 arranged therein to be heated and a second pump 6 . The two heating circuits 1 and 4 can be connected via a valve 7 in such a way that the same liquid heating medium flows through these circuits. Specifically, the valve 7 is implemented as a clock-pulsed reversing valve, so that the heat exchange between the first and the second heating circuit 1 and 4 can be adjusted. Optionally, valve 7 can also be implemented as a mixing valve. In addition, the first heating circuit 1 also includes a check valve 8 arranged between the two connecting pipelines leading to the second heating circuit 4, a check valve 8 arranged in the figure 1 A heat exchanger 10 and a compensating tank 11 in the passenger compartment 9 of the vehicle of the arrangement shown in .

Abstract

The invention relates to a motor vehicle. The motor vehicle includes a first heating / cooling circuit (1) with a heat source / sink (2) arranged therein and a first pump (3), and a second heating / cooling circuit with a battery (5) to be heated / cooled arranged therein and a second pump (6). 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. In particular, also in the second heating / cooling circuit (4) between the valve (7) and the battery (5) is provided with a heat exchanger (12) and / or a fluid reservoir and / or a cyclone and / or a long circuit. Furthermore, the invention also relates to a method of operating the motor vehicle.

Description

technical field [0001] The invention relates to a motor vehicle comprising a first heating / cooling circuit and a second heating / cooling circuit, wherein the first heating / cooling circuit has a heat source / sink and a first heating / cooling circuit arranged therein. pump, while the second heating / cooling circuit has a battery and a second pump disposed therein to be heated / cooled. Furthermore, the invention relates to an operating method for such a vehicle. Background technique [0002] Heating / cooling circuits for motor vehicle batteries (accumulators) have long been known. The high-power batteries of electric and hybrid vehicles in particular are usually tempered so that they operate in a temperature range favorable for their performance. Therefore, it is necessary to cool the battery when the external temperature is high, and to heat the battery when the external temperature is low. [0003] For example, DE 42 39 834 A1 discloses heating the battery by means of a fuel hea...
