[0034] like Figure 1 As shown, in some embodiments, the battery cabinet 10 includes a plurality of battery receiving chambers 100 for receiving batteries, and also includes a battery cabinet temperature detection device, and a battery formation device and / or a battery capacity division device. The battery cabinet temperature detection device, the battery formation device and the battery capacity division device are all connected to the battery receiving chambers 100.

[0035] It is understood that the battery cabinet 10 proposed in this embodiment may include a battery formation device or a battery capacity division device, or may include both a battery formation device and a battery capacity division device. It should be noted that when performing formation or capacity division operations on the battery, the temperature of the battery needs to be detected. The battery cabinet temperature detection device of this embodiment is used to detect the temperature of the battery in the battery cabinet 10.

[0036] After the battery is assembled, it is not charged and needs to be charged and activated. The process of charging the battery to activate the battery is called battery formation. The battery formation device is a device for charging the battery in the battery receiving chamber 100 to activate the battery.

[0037] The battery capacity division device is used to perform capacity tests on the batteries in each battery receiving chamber 100 to achieve battery qualification testing. Capacity division is a charging and discharging operation on the battery. The capacity of the battery is determined by testing the discharge capacity of the battery during capacity division. Only when the tested battery capacity meets the battery design capacity, the battery is qualified.

[0038] This embodiment does not improve the structure of the above-mentioned battery formation device and / or battery capacity division device. The specific battery formation and battery capacity division methods are all conventional, which will not be described in detail here.

[0039] The battery cabinet temperature detection device in the battery cabinet 10 of the present application is described in detail below.

[0040] In some embodiments, a battery cabinet temperature detection device is applied to a battery cabinet 10. As described above, the battery cabinet 10 includes a plurality of battery receiving chambers 100 for receiving batteries. The battery cabinet temperature detection device includes an optical fiber temperature measurement component. The optical fiber temperature measurement component is arranged in the battery cabinet 10 corresponding to each battery receiving chamber 100 and is used to detect the temperature of the batteries in each battery receiving chamber 100.

[0041] Among them, the optical fiber temperature measurement component is a device for temperature detection based on optical fiber temperature measurement technology. Optical fiber temperature measurement is a type of optical fiber sensing technology. It senses temperature changes through optical fiber sensors and converts temperature data into optical signals to realize the collection and measurement of temperature data. For example, the optical signal generated by the light source is transmitted to the location of the temperature sensor through the optical fiber. The temperature sensor is affected by temperature, causing changes in optical properties. Similar changes can be reflected by the intensity, frequency or phase of the optical signal. The changes in the optical signal are analyzed and processed by the spectrum analyzer and the data acquisition system, and finally the temperature-related data are obtained. Optical fiber temperature measurement has high measurement accuracy and anti-interference ability, and can be applied to scenarios that require high-precision temperature monitoring. In addition, optical fiber temperature measurement also has the advantages of corrosion resistance, high sensitivity, accurate temperature measurement, good timeliness, long service life, small size and flexibility, which is convenient for the layout of the device to be tested.

[0042] In some further embodiments, the optical fiber temperature measurement assembly includes an optical fiber 210 and a temperature measuring element 220. The optical fiber 210 has temperature measuring points regularly distributed corresponding to each battery receiving chamber 100. The temperature measuring element 220 is matched with each temperature measuring point and is used to detect the battery temperature by collecting the temperature of each temperature measuring point.

[0043] In the optical fiber temperature measurement assembly of the present embodiment, a plurality of temperature measurement points are provided on the optical fiber 210, and temperature measurement components 220 are provided corresponding to the temperature measurement points. That is, a plurality of temperature measurement components 220 are provided on one transmission optical fiber 210. Temperature detection of a plurality of temperature measurement components 220 can be achieved by using one transmission optical fiber. In order to ensure the accuracy of temperature measurement of each battery receiving chamber 100 of the battery cabinet 10, temperature measurement points corresponding to the battery receiving chamber 100 are regularly distributed on the optical fiber 210, that is, each temperature measurement point is at the same position as the corresponding battery receiving chamber 100. For example, a temperature measurement point is provided at a first preset position on the left side wall of each battery receiving chamber 100, or a temperature measurement point is provided at a second preset position on the right side wall of each battery receiving chamber 100, or a temperature measurement point is provided at a third preset position at the bottom of each battery receiving chamber 100. The regular distribution of temperature measurement points facilitates processing and arrangement, and can improve the processing efficiency of the battery cabinet temperature detection device.

[0044] It can be understood that this embodiment has no limitation on the location of the temperature measuring point, and the location of the temperature measuring point can be customized according to the actual application.

[0045] Exemplarily, the temperature measuring point can be set according to the position of the battery receiving chamber 100 in the battery cabinet 10. Since each battery receiving chamber 100 will accommodate a battery, a temperature measuring point is set at the position of each battery receiving chamber 100. Since the optical fiber 210 has the characteristic of being bendable, one optical fiber 210 can meet the effect of being spread throughout the battery cabinet 10. In this embodiment, the temperature measuring element 220 is set based on one optical fiber 210 to realize temperature testing, which reduces the number of sampling lines during temperature detection and greatly saves occupied space.

[0046] In some specific embodiments, the temperature measuring element 220 is a temperature measuring grating. The temperature measuring grating is a sensor for measuring the temperature of a temperature measuring point. Through optical principles and optical fiber sensing technology, the temperature measuring point is divided into several small parts, each of which can be called a grid point. By measuring the optical fiber temperature of the grid point, the temperature value of the position can be determined.

[0047] In other embodiments, the optical fiber 210 is arranged in a serpentine shape in the battery cabinet 10 and spreads throughout each battery receiving chamber 100 .

[0048] Figure 2 Shown Figure 1 A schematic diagram of the structure of the battery cabinet 10 in direction A. Figure 2 The concave structure shown in the figure is the battery receiving chamber 100 for receiving the battery. In order to allow the optical fiber 210 to efficiently traverse all the battery receiving chambers 100 in the battery cabinet 10, as shown in FIG. Figure 2 As shown by the green distribution line, the optical fiber 210 is arranged in a serpentine shape in the battery cabinet 10, and sequentially traverses each battery receiving chamber 100. The serpentine arrangement can reduce the length of the optical fiber 210 as much as possible while traversing all battery receiving chambers 100 in the battery cabinet 10.

[0049] In one implementation, in order to reduce the detection error of the battery temperature of all battery storage chambers 100 in the battery cabinet 10, the same temperature measurement point position is set corresponding to each battery storage chamber 100 to avoid the detection difference caused by the position difference of the temperature measurement point. Figure 2 As shown in the example, the temperature measuring points corresponding to each battery containing chamber 100 are located in the same plane to ensure the consistency of the temperature of the battery containing chamber 100 collected by each temperature measuring point.

[0050] In some specific embodiments, the optical fiber 210 is arranged in a serpentine shape on the side wall of the battery receiving chamber 100 ; or, the turning points of the optical fiber 210 are arranged at intervals on the bottom of the battery receiving chamber 100 .

[0051] The side wall of the battery storage chamber 100 is any side of the battery storage chamber 100 in the battery cabinet 10. When the optical fiber 210 is arranged to traverse the battery cabinet 10, the optical fiber can be arranged along the side wall of the battery storage chamber 100. In order to ensure the consistency of the setting position of the temperature measuring element 220 on the optical fiber 210, the optical fiber 210 regularly traverses the battery storage chamber 100 of the battery cabinet 10.

[0052] For example, please refer to Figure 3 , Figure 3 Shown Figure 1 The top view of the battery cabinet 10 in FIG. 1 also uses green distribution lines to represent the optical fiber 210. Figure 3 As shown, the optical fiber 210 is arranged in a serpentine shape along the side wall of the battery storage chamber 100, and passes through each battery storage chamber 100 in sequence. In this embodiment, the temperature detection of the batteries in all the battery storage chambers 100 in the battery cabinet 10 can be achieved through one optical fiber 210, avoiding cumbersome wiring. At the same time, the serpentine arrangement of the optical fiber 210 in this embodiment reduces the length of the laid optical fiber 210 and also reduces the cost of the battery cabinet temperature measuring device.

[0053] In another implementation, see Figure 2 ,Right now Figure 1 Schematic diagram of the battery cabinet 10 in the A direction. When traversing the battery storage chamber 100, the optical fiber 210 passes through the side wall and the bottom of the battery storage chamber 100 in turn, and passes through the bottom of the battery storage chamber 100 and enters the adjacent battery storage chamber 100 from the other side wall of the same battery storage chamber 100. At this time, the contact distance between the optical fiber 210 and the battery storage chamber 100 is long. By setting a temperature measuring point on the optical fiber 210 in this structure, the battery temperature at any position in the battery storage chamber 100 can be measured. In one feasible method, multiple temperature measuring points can also be set in the same battery storage chamber 100 to achieve multi-point temperature detection of the battery and improve the accuracy of battery temperature detection.

[0054] In some exemplary embodiments, each battery receiving chamber 100 includes a receiving groove for receiving the optical fiber 210 and / or the temperature measuring element 220 .

[0055] The receiving groove is a groove arranged in the battery receiving chamber 100 for receiving the optical fiber 210 and / or the temperature measuring element 220 .

[0056] In some specific embodiments, the receiving groove is disposed on the side wall and / or the bottom wall of the battery receiving chamber 100 .

[0057] The optical fiber 210 or the temperature measuring element 220 is arranged in the receiving groove, which is convenient for installing and positioning the optical fiber 210 or the temperature measuring element 220, and the position of the optical fiber 210 or the temperature measuring element 220 can be determined quickly and accurately. At the same time, the arrangement of the receiving groove can also reduce the contact between the optical fiber 210 or the temperature measuring element 220 and the battery in the battery receiving chamber 100, play a protective role for the optical fiber 210 or the temperature measuring element 220, and improve the durability of the optical fiber 210 or the temperature measuring element 220.

[0058] Exemplarily, the battery receiving chamber 100 may be provided with only an optical fiber receiving groove for receiving the optical fiber 210, so as to facilitate the installation and layout of the optical fiber 210. Alternatively, the battery receiving chamber 100 may also be provided with only a temperature measuring component receiving groove for receiving the temperature measuring component 220, so as to facilitate the installation and setting of the temperature measuring component 220. Alternatively, the battery receiving chamber 100 may also be provided with both an optical fiber receiving groove for receiving the optical fiber 210 and a temperature measuring component receiving groove for receiving the temperature measuring component 220, so as to facilitate the installation, setting and positioning of the optical fiber 210 and the temperature measuring component 220.

[0059] In some further embodiments, the battery receiving chamber 100 includes a plurality of receiving slots for receiving the temperature measuring element 220 , so as to realize multi-point detection of the battery.

[0060] Among them, each battery holding chamber 100 can be set with the number of receiving slots for accommodating the temperature measuring element 220 according to actual conditions. For example, a receiving slot for accommodating the temperature measuring element 220 is set in the battery holding chamber 100 to realize a single-point temperature test of the battery. Alternatively, a plurality of receiving slots for accommodating the temperature measuring element 220 are set in the battery holding chamber 100 to realize multi-point temperature testing of the battery. The setting cost of a single temperature measuring point is not high, and the temperature detection of all batteries in the battery cabinet 10 can be realized more quickly, thereby improving the detection efficiency. However, the temperature detection of a single temperature measuring point may not be able to fully reflect the temperature condition of the battery, especially in scenarios with high accuracy requirements. Multi-point temperature testing of the battery can obtain the temperature data of the battery more comprehensively and accurately, thereby improving the reliability of temperature detection of the battery cabinet 10.

[0061] For example, please continue to refer to Figure 4 . Figure 4The figure shows a schematic diagram of an optical fiber 210 with multiple temperature measurement points distributed. Figure 4 As shown, for each battery storage chamber 100, the optical fiber 210 can be a straight line. When the size of the battery storage chamber 100 is large, the optical fiber 210 can also be distributed in a serpentine shape in the battery storage chamber 100. When the optical fiber 210 is also distributed in a serpentine shape in the battery storage chamber 100, the temperature measurement points are regularly distributed on the optical fiber 210 to achieve multi-point temperature measurement of the batteries in the battery storage chamber 100. At this time, in order to ensure the consistency of battery temperature monitoring in all battery storage chambers 100 in the battery cabinet 10, the distribution of the optical fiber 210 and the temperature measuring element 220 corresponding to each battery storage chamber 100 are the same.

[0062] In some embodiments, the receiving slot is an open slot, and the receiving slot further includes a detachable slot cover.

[0063] The open groove is a groove with an opening. The optical fiber 210 or the temperature measuring element 220 can be placed in the receiving groove through the opening of the receiving groove. The setting of the open groove facilitates the adjustment and replacement of the optical fiber 210 or the temperature measuring element 220. In addition, the setting of the open groove can make it possible to have no obstruction between the temperature measuring element 220 and the battery in the battery receiving chamber 100, which is convenient for the temperature measuring element 220 to measure the temperature of the battery, and can improve the accuracy of the temperature measurement of the battery in the battery receiving chamber 100.

[0064] In one implementation, when the receiving groove is an open groove, the receiving groove also includes a removable groove cover, which is used to close the receiving groove through the groove cover, and enclose the optical fiber 210 and / or the temperature measuring component 220 in the receiving groove to achieve protection for the optical fiber 210 and / or the temperature measuring component 220.

[0065] In some other embodiments, the depth of the receiving groove is not less than the height of the optical fiber 210 or the temperature measuring element 220 placed in the receiving groove.

[0066] Among them, the receiving groove is a groove for receiving the optical fiber 210 or the temperature measuring component 220, and the optical fiber 210 and / or the temperature measuring component 220 are devices received in the receiving groove. The depth of the receiving groove is set to be not less than the height of the device in the receiving groove, that is, when the optical fiber 210 or the temperature measuring component 220 is received in the receiving groove, the surface corresponding to the notch of the receiving groove of the optical fiber 210 or the temperature measuring component 220 and the notch of the receiving groove are flush with or lower than the notch. This setting facilitates the temperature measuring component 220 to detect the temperature of the battery in the battery receiving chamber 100. In addition, when the battery is assembled and inserted into the battery receiving chamber 100, since the optical fiber 210 and the temperature measuring component 220 are hidden in the receiving groove, it is possible to avoid damage to the optical fiber 210 or the temperature measuring component 220 when the battery is inserted into the battery receiving chamber 100, thereby improving the reliability of the temperature detection device.
