Problems solved by technology

On the other hand, in summer, the temperature of the vehicle body 200 rises to a high temperature, so that the battery pack 1100 in contact with the vehicle body 200 is overheated.
[0009] Thus, with the above-described structure in which the battery pack 1100 is in contact with the vehicle body 200, in some cases, the battery pack 1100 is excessively cooled or heated, and thus sufficient power storage performance cannot be obtained.

Embodiment Construction

[0043] Exemplary embodiments of the present invention are described below.

[0044] First, refer to figure 1 to FIG. 3 describe a temperature adjustment mechanism according to a first exemplary embodiment of the present invention. figure 1 is an exploded sectional view of the temperature adjustment mechanism of the first example embodiment, Figure 2A is a perspective view of the temperature adjustment mechanism of the first example embodiment, Figure 2B is a side view of the temperature adjustment mechanism of the first example embodiment. Figure 3A and Figure 3B is a schematic diagram showing the internal structure of the temperature adjustment mechanism of the first exemplary embodiment.

[0045] The first housing part 1 has an opening 11 for a battery unit 2 which will be described later. Radiating fins 12 are formed on the outer surface of the first case member 1 in order to promote heat radiation from the first case member 1 (ie, heat radiation from the battery...

Abstract

A temperature adjustment mechanism has: a case (30) containing a power source (20) and a first heat transfer medium (4) for cooling the power source (20) and integrated with or contacting a heat transfer portion; and a drive device (51) for delivering the first heat transfer medium (4) between the inside and the outside of the case (30). The drive device (51) delivers the first heat transfer medium (4) to the outside of the case (30) to establish a first state in which a layer (AS) of a second heat transfer medium is created in a region of the case (30) on the heat transfer portion side of the power source (20), and the drive device (51) delivers the first heat transfer medium to the inside of the case (30) to establish a second state in which at least a portion of the region of the case (30) is filled with the first heat transfer medium (4).

Description

technical field [0001] The present invention relates to a thermostat, a method for controlling the thermostat, and a vehicle having the thermostat, all of which are adapted to prevent an excessive increase or decrease in temperature of a power source. Background technique [0002] Various hybrid vehicles, fuel cell vehicles, and electric vehicles run on the driving force of electric motors. Such motor-driven vehicles often use secondary batteries or capacitors (capacitors) to store electrical energy to be supplied to the electric motor. The performance and life of a secondary battery largely depend on the ambient temperature. In particular, charging and discharging a secondary battery at a high temperature can significantly deteriorate the secondary battery. [0003] Considering the above problems, for example, in Japanese Patent Application Laid-Open No. 09-259940 (JP-A-09-259940), No. 11-307139 (JP-A-11-307139), No. 2001-319697 (JP -A-2001-319697) and No. 09-167631 (JP-...
