Description
Technical Field
The invention relates to the technical field of battery energy storage, in particular to a self-adaptive adjusting device for air cooling and heat management of a battery box.
Background
The energy storage means that energy in the form of electric energy and the like is stored in a certain form through different media and is released to do work (or generate electricity) when required. In recent years, with the increasing of installed capacity of new energy power generation in China, the proportion of new energy power generation in total power generation is higher and higher. The instability of new energy power generation such as wind power and photovoltaic brings challenges to the stable operation of a power grid. In some areas with sufficient photovoltaic and wind power resources, the problem of power limitation is outstanding, and large direct and indirect losses are brought to power generation enterprises. Therefore, an energy storage form with high proportion, ubiquitous and wide-area cooperation is constructed, the form, the structure and the function of a traditional power system are changed through new energy and energy storage, and the method has important significance for solving the problems of power grid stability and new energy power generation and electricity limitation.
The battery energy storage technology realizes the storage and output of electric energy by utilizing the conversion between the electric energy and the chemical energy, not only has the technical characteristics of quick response and bidirectional adjustment, but also has the technical advantages of strong environmental adaptability, small-sized dispersed configuration and short construction period, and is in a high-speed growth situation in the field of energy storage in recent years. The battery energy storage is mainly based on the technologies of lithium ion batteries, flow batteries, lead storage batteries, sodium-based batteries and the like. Among them, lithium ion batteries are the most widely and mature in battery energy storage commercial application due to the advantages of large specific energy, long cycle life, low self-discharge rate, wide allowable working temperature range, good low-temperature effect, and the like.
The core device of the battery energy storage is a battery cluster and a thermal management system. The battery cluster is composed of a plurality of battery boxes 1, and a plurality of battery cores 2 which are arranged in groups according to the row and column rule are arranged in each battery box 1. The stored energy of the battery generates heat in the charging and discharging processes. This heat is a major factor that causes the battery energy storage system to be unsafe. Research has shown that temperature has a great influence on the capacity, power and safety of the battery. In a battery energy storage system, the battery capacity and power are larger due to the large number of batteries aggregated. A large amount of batteries are closely arranged in a certain space, and the operation working condition is complex and changeable, which easily causes the problems of uneven heat generation, uneven temperature distribution, large temperature difference between batteries and the like. In the past, the charge and discharge performance, capacity, service life and the like of partial batteries are reduced, so that the performance of the whole battery energy storage system is influenced, thermal runaway is caused in severe cases, and major accidents are caused.
One of the most common thermal management methods currently used to remove heat generated during the charging and discharging of the battery is through air convection cooling. As shown in fig. 1 and 2, a fan 3 is installed at one side of the battery box 1, and the battery cell 2 is cooled by a suction action of the fan 3. However, with the above-described air convection cooling method, air mainly flows from left to right along the gap between the cells 2, and does not flow laterally, resulting in insufficient cooling of the lateral surfaces of the cells 2. Most importantly, in the process of flowing air from left to right, due to heat absorption, the temperature of the air is continuously increased, and the cooling capacity is gradually reduced, so that the temperature of each cell 2 in the battery box 1 is unevenly distributed, as shown in fig. 3, the temperature of the cell 2 on the left side (close to the air inlet side) is low, and the temperature of the cell 2 on the right side (close to the air inlet side) is high, so that the temperature of the local cell 2 is too high, and on one hand, a thermal management protection system is possibly triggered, so that the energy storage of the battery stops running; on the other hand, the local battery cell 2 runs at a higher temperature for a long time, so that the charge and discharge performance, capacity, service life and the like are reduced; on the other hand, in the design process, in order to ensure that all the battery cells 2 are within the safe temperature range, the local battery cell 2 temperature in the high-temperature region needs to be taken as a control target, and then the fan 3 generating a larger air flow needs to be adopted, so that the power consumption is higher, and the operation cost of battery energy storage is increased.

When the air cooling mode is adopted for heat management of the battery box, the air temperature is continuously increased and the cooling capacity is gradually reduced in the process that air flows along the battery core, so that the temperature of the battery core close to the air inlet side in the battery box is low, and the temperature of the battery core close to the fan inlet side is high. The bracket under the battery cell close to the inlet side of the fan gradually deforms along with the temperature rise of the battery cell, on one hand, the position of the battery cell is changed by the deformation of the bracket, so that the space between the battery cells in the middle area is increased, the space between the battery cells and the upper and lower side surfaces is reduced, more air is ensured to flow through the gap between the battery cells in the middle area, and the battery cells are conveniently cooled; on the other hand, because the support takes place deformation for corresponding electric core position changes, makes the clearance between the higher in bank electricity core of temperature and the lower in bank electricity core of temperature stagger each other, further can increase the circulation of air passageway, is convenient for cool off electric core, thereby can avoid local electric core high temperature, has realized the self-adaptation regulation of battery box thermal management, need not increase fan power, also need not be with the help of external means. Under the condition of the same air flow, the local high-temperature area of the battery cell in the air convection cooling heat management is reduced, the temperature uniformity of each battery cell in the battery box is improved, and the service life and the operation safety of the battery cell in the battery box can be further improved.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
It should be noted that the air-cooling heat-management adaptive adjusting device of the battery box is suitable for the battery box 1 which performs heat management on the battery core in an air-cooling mode, does not change an air-cooling facility, and still belongs to the field of performing heat management on the battery core 2 in the air-cooling mode.
As shown in fig. 4 to 7, multiple rows of battery cells 2 are disposed in a battery box 1 for thermally managing the battery cells 2 by using an air cooling method, the battery cells 2 in fig. 4 are arranged in a matrix form, each row can be regarded as a row, the multiple rows of battery cells 2 are disposed at intervals, and multiple battery cells 2 in the same row are disposed at intervals; the right side of battery box 1 is provided with fan 3 for the air flows to the right side from the left side of battery box 1 through the suction effect of fan 3, and at the in-process that the air flows, carries out the heat exchange with electric core 2, realizes the cooling to electric core 2. In this embodiment, the thermal management adaptive adjustment device includes one or more brackets 4, the plurality of brackets 4 are arranged in a row in the battery box 1, one bracket 4 is respectively arranged below one row or a plurality of rows of battery cells 2, each bracket 4 is provided with a plurality of slots 41, each slot 41 is used to fix one battery cell 2, and the battery cells 2 are fixed by the slots 41 of the brackets 4. The support 4 is made of a shape memory material, and the shape memory material can deform along with temperature change. As shown in fig. 6 to 8, when the temperature of the electric core 2 rises, the support 4 deforms accordingly, so that the distance between the adjacent electric cores 2 increases, the air circulation channel is increased, the cooling air flow is changed, the heat exchange effect is improved, the cooling effect on the electric core 2 is improved, the condition that the temperature of the local electric core 2 is uneven in the battery box 1 is avoided, and the adaptive adjustment of air cooling and heat management is realized. Preferably, the higher the temperature of the battery cell 2 is, the larger the deformation amount of the bracket 4 below the battery cell 2 is, so as to increase the distance between the battery cells 2, further improve the air circulation, and improve the cooling effect.
The shape memory material has the characteristic of generating shape change along with temperature change, and the shape can also return to the original shape along with the recovery of the temperature. In this embodiment, the shape memory material is a thermally induced polymer. The shape response temperature of the support 4 is 30-35 ℃, and can be 31 ℃, 32 ℃, 33 ℃ or 34 ℃ and the like, so as to meet the temperature control requirement of the battery core 2. In other embodiments, the shape memory material may be in other types of forms as long as it deforms with increasing temperature.
It should be noted that the deformation of the support 4 occurs along the length direction of the support 4, and the deformation amount is larger as the temperature is higher, in this embodiment, the length direction of the support 4 is perpendicular to the width direction of the battery cell 2. For the electric core 2 in the same row, because the electric core 2 located at both sides has the air cooling from the side wall gap, the electric core 2 located at the middle area only has the air cooling from the gap between the adjacent electric cores 2, so that the temperature of the electric cores 2 at both sides is higher than that of the electric cores 2 at the middle area, and then the deformation of the supports 4 at both sides is smaller than that of the supports 4 at the middle area, after the supports 4 deform, the distance between the electric cores 2 at the middle area is increased, so that the air circulation channel between the electric cores 2 is increased, and the air cooling effect is enhanced.
Under the suction effect of one side fan 3, the air flows from the left side to the right side, takes place heat exchange at the flow in-process for air temperature risees from the left side to the right side gradually, and cooling capacity descends gradually, and then it is better to be located left electric core 2 cooling effect, makes to be located left electric core 2 temperature lower, need not to change this part air circulation passageway, then need not to set up the support 4 of shape memory material preparation at this part. Preferably, the number of the brackets 4 is smaller than the number of rows of the battery cells 2, so that the brackets 4 are arranged under only a part of the battery cells 2 with higher temperature, and when the temperature of the part of the battery cells 2 rises, the corresponding brackets 4 deform to change the flow rate of the circulating air. Further, preferably, a plurality of the brackets 4 are all arranged on one side of the battery box 1 close to the fan 3, and the bracket 4 is not arranged on one side of the battery box 1 far away from the fan 3. As shown in fig. 4, in the present embodiment, four rows of battery cells 2 are disposed in the battery box 1, the support 4 is disposed below only two rows of battery cells 2 on the side close to the fan 3, and the support 4 is not disposed below the battery cells 2 on the side far from the fan 3.
In this embodiment, the support 4 is a truss structure, and the length direction of the truss structure can deform along with the temperature rise. Set up support 4 into the installation of truss-like structure can make things convenient for support 4 under electric core 2, and when support 4 took place deformation, can make the position of electric core 2 with one row all change, avoid the interval between partial electric core 2 to receive the extrusion of support 4 deformation and reduce.
In this embodiment, draw-in groove 41 is the U type, including cell bottom and the cell wall that two relative intervals set up, and every cell wall all laminates the outer wall of electricity core 2, and the bottom surface of electricity core 2 is placed on the cell bottom, and when electric core temperature rose, the cell bottom took place deformation along length direction for interval between the adjacent draw-in groove 41 changes, and then makes interval between the adjacent electricity core change. In this embodiment, the width of the groove wall is smaller than the length of the battery cell 2, and the central axis of the clamping groove 41 is parallel to the axis of the battery cell in the width direction. The height of the cell walls is much less than that of the cells, so that the cell walls are prevented from influencing the air flow between the cells.
In this embodiment, the same number of the slots 41 on the support 4 is equal to the number of the cells 2 in the same row of the cells 2, each slot 41 on the same support 4 is provided with a cell 2, and each slot 41 is provided below each cell 2 in the same row of the cells 2 on the same support 4. It should be noted that, in other embodiments, because the cells 2 located on both sides have air cooling from the side walls, and the temperature is lower than the cell temperature in the middle area, at this time, the number of the card slots 41 on the same bracket 4 may also be smaller than the number of the cells in the same row of cells 2, that is, the card slots 41 are only disposed below the cells 2 in the middle area, so as to increase the distance between the cells 2 in the middle area, and increase the air circulation channel. It should be noted that the middle area refers to the middle area of the same row of cells 2.
Taking the battery box 1 shown in fig. 4 as an example, the working principle of the invention is explained as follows:
set up four rows of electric core 2 in the battery box 1, from left to right be first row, second row, third row and fourth row respectively, every row is provided with six electric core 2, and the right side of battery box 1 is provided with fan 3, adopts the air cooling mode to manage thermal management to battery box 1, and the third row of electric core 2 that is close to fan 3 all is provided with shape memory material preparation's support 4 below with fourth row of electric core 2.
In the working process of the battery box 1, the temperature of the right battery cell 2 close to the fan 3 is high, so that the support 4 deforms. The higher the temperature is, the larger the deformation amount is, and the deformation is accumulated along the length direction, so that the cell interval of the middle area of the same row of cells 2 is increased, and the distance between the upper side and the lower side of the cell 2 is reduced, therefore, more air can flow through the gap between the cells 2 in the middle area, so that the air circulation channel is changed, and by changing the positions of the cells, the change of the air flow between the cells is realized, so that the self-adaptive adjustment of the thermal management of the battery box can be realized without changing the power of the fan 3, wherein arrows in fig. 4 and 6 indicate the air flow direction. As shown in fig. 6, taking the third row of cells 2 as an example, because the position of the cells 2 is shifted due to the deformation of the support 4, and the distance between the cells 2 in the middle area is increased, the gap between the adjacent cells in the second row and the gap between the adjacent cells in the third row are misaligned, so that the air flowing out from the cells in the second row has an impact effect on the cells in the third row, and the cooling effect can be further enhanced. Further, as shown in fig. 8, at the same air flow rate, although the temperature of the battery cells near the upper and lower side surfaces is increased, the temperature of the battery cell 2 in the middle area is significantly reduced, the uniformity of the temperature of each battery cell in the battery box 1 is greatly improved, and the safety of battery energy storage is improved due to the elimination of the local high-temperature area.
In summary, the embodiment of the present invention provides an adaptive air-cooling and heat-managing adjustment apparatus for a battery box, which supports a battery cell 2 in a battery box 1 by using a support 4 made of a shape memory material, so that the shape of the support 4 can change along with the temperature change of the battery cell 2. When the air cooling mode is adopted for heat management of the battery box, in the process that air flows along the battery core 2, the air temperature is continuously increased, and the cooling capacity is gradually reduced, so that the temperature of the battery core 2 close to the air inlet side in the battery box 1 is low, and the temperature of the battery core 2 close to the air inlet side of the fan 3 is high. The support 4 under the battery cells 2 close to the inlet side of the fan 3 gradually deforms along with the temperature rise of the battery cells 2, so that on one hand, the distance between the battery cells 2 in the middle area is increased and the distance between the battery cells 2 from the upper side surface to the lower side surface is reduced in the same row of the battery cells 2, more air is ensured to flow through the gaps between the battery cells in the middle area, and the battery cells 2 are conveniently cooled; on the other hand, because support 4 takes place deformation for corresponding electric core 2's position changes, make the higher in bank electric core 2 of temperature and the lower in bank electric core 2 of temperature clearance between stagger each other, further can increase the circulation of air passageway, be convenient for cool off electric core 2, thereby can avoid local electric core 2 high temperature, realized the self-adaptation regulation of battery box thermal management, need not increase fan 3's power, also need not be with the help of external means. Under the condition of the same air flow, the local high-temperature area of the battery core in the air convection cooling heat management is reduced, the temperature uniformity of each battery core 2 in the battery box 1 is improved, and the service life and the operation safety of the battery core 2 in the battery box 1 can be further improved.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
