[0002] Existing technologies usually use DTS (Distributed Temperature Sensing), a distributed optical fiber temperature measurement system, to detect the temperature of the power battery static warehouse to determine whether the power battery has problems such as spontaneous combustion, failure, thermal runaway, etc.

[0003] However, the existing DTS has the disadvantages of low positioning accuracy, which is prone to positioning errors and thus delays rescue time, and large sampling intervals resulting in low temperature measurement sensitivity and poor temperature measurement reliability.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 As shown, the utility model provides a temperature detector for a battery storage warehouse, including multiple contact temperature sensors 2. The contact temperature sensors 2 use ultra-thin thermistors as temperature sensing units. The temperature sampling points 3 of each contact temperature sensor 2 are distributed at different points in the battery storage warehouse 1.

[0019] Among them, the contact temperature sensor 2 uses the principle of heat conduction to contact an object to detect the object's temperature. When measuring an object with a large heat capacity such as a battery 6, its measurement accuracy is higher than that of the non-contact temperature sensor 2. An ultra-thin thermistor refers to a resistor with a very small thickness, which is usually in the nanometer scale and has a very small volume. It has the advantages of high sensitivity and fast response speed.

[0020] Specifically, the number of the contact temperature sensors 2 can be as follows: Figure 1 The 8 shown, accordingly, Figure 1 There are also 8 temperature sampling points 3 in the battery storage 1. The contact temperature sensor 2 and the temperature sampling point 3 can be connected by pipelines. The temperature sampling point 3 can be connected to the outer wall of the battery 6 by attachment. Of course, the temperature sampling point 3 can also be set to be suspended in the air in the battery storage 1. The pipeline can be bent and folded and set as long as possible, so theoretically the temperature sampling points 3 can be freely distributed and set in any empty space in the battery storage 1.

[0021] Preferably, each temperature sampling point 3 is attached to the outer wall of the battery 6 in the battery storage warehouse 1, which is conducive to giving full play to the characteristics of the contact temperature sensor 2 as much as possible.

[0022] In this embodiment, by adopting a plurality of contact temperature sensors 2 with ultra-thin thermistors as temperature sensing units to detect the temperature of the surface of the battery 6 or the environment in the battery static warehouse 1, the advantages of the contact temperature sensor 2 and the ultra-thin thermistor can be utilized to accelerate the response speed and improve the temperature measurement sensitivity, and by dispersing the temperature sampling points 3 of each contact temperature sensor 2 in the battery static warehouse 1, the sampling points are as many and as small as possible, thereby facilitating the reduction of the sensing area and increasing the sampling density, which is beneficial to improving the positioning accuracy and temperature measurement reliability.

[0023] In an optional embodiment, the contact temperature sensor 2 is electrically connected to an alarm device, and when the temperature value collected at a certain temperature sampling point 3 increases to a preset value within a preset period of time, the alarm device is triggered and sounds an alarm.

[0024] Specifically, when it is detected that the temperature in the battery storage warehouse 1 increases abnormally and rapidly, it can be determined that a fault has occurred therein, and an alarm warning needs to be issued at this time.

[0025] In another embodiment, the contact temperature sensor 2 is electrically connected to an alarm device, and when the temperature value collected by a certain temperature sampling point 3 reaches a preset threshold, the alarm device is triggered and sounds an alarm.

[0026] Specifically, when it is detected that the temperature in the battery storage warehouse 1 is abnormally high, it can be determined that a fault has occurred therein, and an alarm warning needs to be issued at this time.

[0027] Furthermore, the above two alarm types can be used separately, but are preferably used at the same time to avoid omission of faults as much as possible.

[0028] In an optional implementation, the contact temperature sensor 2 is disposed on the top of the battery storage warehouse 1 .

[0029] Specifically, the top plate 4 of the battery resting warehouse 1 is generally a flat metal plate or a phenolic plate. The metal plate generally has good heat transfer performance, and the phenolic plate is usually wrapped with aluminum foil on the outside, so the heat conduction of the top plate 4 is very fast, and its heat transfer is very rapid. On the other hand, the hot air flow in the battery resting warehouse 1 will flow from bottom to top to the top of the battery resting warehouse 1. The combination of the two makes the heat transfer in the top area very fast. Therefore, by arranging the contact temperature sensor 2 at the top of the battery resting warehouse 1, it is convenient to arrange the temperature sampling point 3 at the top of the battery resting warehouse 1 as much as possible, which is conducive to further improving the temperature measurement sensitivity; in addition, by identifying whether there is a hot air flow rising in the battery resting warehouse 1, it is possible to indirectly judge whether the battery 6 has problems such as thermal runaway.

[0030] In an optional embodiment, a top plate 4 is provided on the top of the battery storage warehouse 1, and a mounting hole is provided on the top plate 4. The contact temperature sensor 2 is provided with a shell 5, and the shell 5 is provided with a buckle. The mounting hole and the buckle are connected by expansion plugs and screws or screw nuts to fix the temperature detector on the top plate 4.

[0031] In another embodiment, a top plate 4 is provided on the top of the battery storage warehouse 1, and the top plate 4 is made of metal. The contact temperature sensor 2 is provided with a shell 5, and the shell 5 is made of magnetic adsorption material. The temperature detector is fixed on the top plate 4 through mutual adsorption between the shell 5 and the top plate 4.

[0032] Specifically, the two installation methods each have their own advantages. The method of fixing with mounting holes, clips, expansion plugs and screws or screw nuts can make the temperature sensor fixation effect more stable, while the method of attaching the contact temperature sensor 2 to the top plate 4 of the battery storage room 1 by magnetic adsorption is more convenient, which can facilitate the movement and replacement of the contact temperature sensor 2.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
