Embodiment 1

[0026] (Embodiment 1) [Structure of temperature controller 10 for battery] figure 1 is a perspective view showing a schematic structure of a temperature controller 10 for a battery according to an embodiment of the present invention. The temperature controller 10 for a battery according to the present embodiment is used to control the temperature of a battery 1 in which a plurality of battery cells 2 are stacked. The battery 1 has a plurality of battery cells 2 . A plurality of battery cells 2 are arranged in a stack along the stacking direction S, and thus form the battery 1 .

[0027] Each battery cell 2 has a flat rectangular parallelepiped box shape. The battery cells 2 are stacked in the thickness direction thereof. The battery cell 2 has an electrode portion (not shown) at its upper end portion. The plurality of battery cells 2 are electrically connected in series to each other via electrode portions. The battery cell 2 generally has a structure obtained in such a w...

Embodiment 2

[0086] (Embodiment 2) In Embodiment 1 described above, an example in which the temperature control portion 30 extends in the horizontal direction was described. When the battery 1 is installed on the vehicle and the temperature controller for the battery 10 is also installed on the vehicle, the position of the temperature controller for the battery 10 relative to the horizontal plane changes as the operating state of the vehicle changes. Specifically, the inclination of the vehicle is greatly different between when the vehicle goes uphill and when the vehicle goes downhill.

[0087] In order to realize the natural circulation of the heat medium for the temperature controller 10 of the battery in any vehicle attitude, the end 62 in which the liquid-phase flow path 60 is connected to the temperature control part 30 must be located at the temperature control part 30 along the vertical direction. The position below the liquid level S1 of the liquid-phase heat medium. In order to ...

Abstract

A temperature controller for a battery, comprising: a temperature control part configured to control the temperature of the battery through a phase change of a heat medium between a liquid phase and a gas phase; a gas phase flow channel flowing out of the temperature control The gas-phase heat medium in the part flows through the gas-phase flow channel; the heat medium cooling part is configured to condense the gas-phase heat medium flowing in from the gas-phase flow channel; and the liquid-phase flow channel through which the liquid-phase heat medium passes The liquid-phase channel flows from the heat medium cooling part to the temperature control part, and the temperature control part and the heat medium cooling part are arranged so that the liquid-phase heat medium in the heat medium cooling part The liquid level is located above the liquid level of the liquid-phase heat medium in the temperature control unit.

Description

technical field [0001] The present invention relates to a temperature controller for a battery, and more particularly, to a temperature controller for controlling the temperature of a battery through a heat medium. Background technique [0002] Since a battery has a problem that its endurance life is reduced when it is exposed to high temperature, it is desirable to properly control the temperature of the battery. Devices for controlling the temperature of batteries have been disclosed in, for example, 2012-226954 (JP 2012-226954 A), 2011-183862 (JP 2011-183862 A), 2009-9888 (JP 2009-9888 A), 2012-227072 (JP 2012 -227072 A) and Japanese Patent Application Publication No. 2013-012700 (JP 2013-012700 A), etc. are disclosed. [0003] JP 2011-183862 A discloses a structure in which, in an on-vehicle battery composed of a plurality of modules, a module is formed by mounting heat pipes on unit cells in a heat-exchangeable manner. Contents of the invention [0004] As described...
