Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to a battery charging and discharging storage location and a battery charging and discharging environment temperature control system. Background Art

[0002] During the charging and discharging process of lithium batteries, the temperature inside the battery will rise, especially in the capacity division stage, when the battery charging and discharging capacity is high and the temperature rise phenomenon will be more obvious.

[0003] In an automated production environment, the battery charging and discharging process is centralized, that is, multiple lithium batteries are concentrated in one storage location for centralized charging and discharging. As the heat of the battery is dissipated, the temperature of the ambient air will also rise, and the batteries in the same storage location will inevitably affect each other. In order to improve efficiency, the factory adopts a multi-layer high storage technology solution. The hot air will move upward, which will further lead to temperature differences between storage locations. That is, the temperature of the upper storage location will be significantly higher than that of the lower storage location, and the difference in battery ambient temperature will directly affect the battery capacity.

[0004] In order to solve the problem of temperature rise during battery charging and discharging, most traditional charging and discharging solutions use air cooling solutions.

[0006] The heat generated by battery charging and discharging will increase the temperature of the warehouse and factory, and then rely on the factory's air cooling equipment to cool the factory, increasing the factory's energy consumption. Utility Model Content

[0050] Embodiment 1

[0051] The battery charging and discharging storage location 100 of this embodiment is shown in FIG. Figure 1 As shown, Figure 1 The battery charging and discharging storage location 100 of this embodiment is schematically shown, comprising: a sealed cavity 110 and a charging and discharging assembly 120 .

[0052] The sealed cavity 110 has high air tightness in a closed state, and is provided with a vacuum air passage 113 connected to an external vacuum source. The vacuum air passage 113 can form a controllable negative pressure difference between the internal environment of the sealed cavity 110 and the external environment or form a vacuum state in the internal environment of the sealed cavity 110 with the cooperation of the external vacuum source. The sealed cavity 110 is used to accommodate the charging and discharging assembly 120, so as to isolate the charging and discharging assembly 120 from the external environment during the charging and discharging process of the battery 600.

[0053] It is understandable that the external vacuum source can be an air pump structure that extracts the gas inside the sealed cavity 110. It can detect the air pressure inside the sealed cavity 110 by configuring an external controller, air pressure sensor and other equipment, thereby determining the working state and making the vacuum degree in the sealed cavity 110 reach a preset value.

[0054] The charge and discharge assembly 120 is disposed in the sealed cavity 110 and is used to charge and discharge the battery 600. It can be generally provided with a tray 700 for fixing the battery 600 and a charge and discharge probe in contact with the electrode of the battery 600. When the battery 600 is placed in place, the charge and discharge assembly 120 charges or discharges the battery 600 according to the pre-set configuration. It can be understood that in some preferred cases, in order to reduce contact heat transfer, the charge and discharge assembly 120 can reduce the contact area between the charge and discharge assembly 120 and the sealed cavity 110 by means of a bracket or the like.

[0055] Preferably, with the cooperation of an external vacuum source connected to the vacuum airway 113, the vacuum degree inside the sealed cavity 110 can be adjusted, and the specific vacuum degree can be set to 10Pa to 101325Pa, and can be automatically controlled on demand. In addition, an air valve can also be set on the vacuum airway 113 to avoid the internal environment of the sealed cavity 110 being connected to the external vacuum source at all times, so that the vacuum degree can be more conveniently controlled. For example, when the required vacuum degree is reached, the air valve that controls the opening and closing of the vacuum airway 113 is closed. At this time, no matter how much the vacuum degree of the external vacuum source is, the vacuum degree in the sealed cavity 110 can be maintained at the required value without adjusting the vacuum degree of the external vacuum source.

[0056] In order to facilitate the access to the battery 600 in the sealed cavity 110, the sealed cavity 110 includes a cavity 111 and a cavity door 112, and the cavity door 112 is sealed and connected to the cavity 111 in an openable and closable manner. In some preferred embodiments, the cavity door 112 can be connected to the cavity 111 in a hinged manner. In addition, a sealing ring is provided between the cavity 111 and the cavity door 112 to ensure the airtightness of the sealed cavity 110 after the cavity door 112 is closed. It can be understood that the openable and closable connection between the cavity 111 and the cavity door 112 can also be a buckle connection, a sliding connection, etc.

[0057] The working process of the battery charging and discharging storage position 100 of this embodiment is as follows: in the charging and discharging preparation stage, after the battery 600 is placed in place, the chamber door 112 is closed, and the sealed chamber 110 is in an airtight state. It is only connected to the outside world through the vacuum airway 113. The vacuum degree of the external vacuum source is controlled, and the air in the sealed chamber 110 is extracted, and finally reaches the preset vacuum degree. At this time, the charging and discharging storage position enters the charging and discharging process. The purpose of the sealed chamber 110 is to isolate the battery 600 from the air and reduce the medium for heat conduction, thereby further reducing the heat conduction between the battery 600 and the battery 600, and between the battery 600 and the environment. After completing charging and discharging, control the external vacuum source to return to normal air pressure.

[0058] The battery charging and discharging storage 100 of this embodiment further includes a cooling component 130. The cooling component 130 is connected to the sealed cavity 110 and is used to speed up the air circulation speed inside the sealed cavity 110 after the charging and discharging component 120 completes the charging state or the discharging state, thereby efficiently removing the heat generated by the battery 600.

[0059] Specifically, the cooling component 130 includes an air inlet channel 131 and an air outlet channel 132 that can be opened or closed. The air inlet channel 131 connects the inside of the sealed cavity 110 with an external high-pressure air source; the air outlet channel 132 connects the inside of the sealed cavity 110 with an external low-pressure air source. Among them, the external high-pressure air source can be an air compressor, an exhaust fan, and other equipment that can transport gas into the sealed cavity 110. The external low-pressure air source can be a reverse fan structure, etc. It can be understood that the high-pressure air source and the low-pressure air source are relative, and the purpose is to make the air in the sealed cavity 110 have a fixed flow direction. Therefore, the low-pressure air source is not necessarily an air source below atmospheric pressure, and it can also be the external atmosphere. As long as the air pressure of the external high-pressure air source is controlled to be higher than atmospheric pressure, the air in the sealed cavity 110 can have a stable flow direction. In addition, in some large-scale production environments, the external high-pressure air source can be some centralized large-scale air pressure regulating equipment.

[0060] On the other hand, in order to cooperate with the vacuuming and breaking of the sealed chamber 110, the opening and closing of the air inlet channel 131 and the air outlet channel 132 can be achieved by the airtight valve 133. In this embodiment, the airtight valve 133 is respectively arranged at the connection between the sealed chamber 110 and the air inlet channel 131 and the air outlet channel 132, which is controlled by an external controller, such as a host computer, and can be opened and closed under the control of the external controller.

[0061] The working process of the battery charging and discharging storage position 100 of this embodiment is as follows: in the charging and discharging preparation stage, the sealed cavity 110 is in an airtight state. At this time, the air inlet channel 131 is closed, the air outlet channel 132 is closed, the vacuum air channel 113 is connected to the external vacuum source, and the air in the sealed cavity 110 is extracted. After reaching the preset vacuum degree, the charging and discharging storage position enters the charging and discharging process. The purpose of the sealed cavity 110 is to isolate the battery 600 from the air and reduce the medium for heat conduction, thereby further achieving the purpose of reducing the heat conduction between adjacent batteries 600 or between the battery 600 and the environment. After the charging and discharging is completed, the air inlet channel 131 and the air outlet channel 132 are opened. Under the action of the external high-pressure air source and the external low-pressure air source, a continuously flowing airflow is formed in the sealed cavity 110, thereby taking away the heat generated by the battery 600 during the charging and discharging process.

[0062] The battery charging and discharging storage 100 of the utility model can maintain the inside of the sealed cavity 110 in a vacuum state during the charging and discharging process by providing a sealed cavity 110 and a vacuum air duct 113 matched therewith, thereby reducing the heat transfer effect between the batteries 600 in the storage, so that the temperature difference of the batteries 600 can be controlled within ±2°C, ensuring the consistency of the temperature of the batteries 600, and further ensuring the consistency of the capacity of the batteries 600. In addition, after the battery 600 completes charging and discharging, the pressure in the sealed cavity 110 is restored to normal pressure, and then the airflow that continuously flows inside is circulated, so as to achieve the purpose of cooling the sealed cavity 110. This process adopts natural wind circulation, and does not adopt an active cooling solution, which effectively controls the energy consumption of cooling the battery 600.

[0063] Embodiment 2

[0064] The battery charging and discharging storage location 100 of this embodiment is similar to that of the first embodiment, and the difference from the first embodiment is that this embodiment further optimizes the charging and discharging assembly 120 .

[0065] Please continue to see Figure 1 In some optimized implementations, in order to facilitate the removal of the battery 600, the charge and discharge assembly 120 includes a lifting mechanism 121 and a charge and discharge probe group 123 disposed above the lifting mechanism 121. The lifting mechanism 121 can be lifted and lowered inside the cavity 111, and the battery 600 disposed on the upper portion thereof is lifted during the lifting process. At the same time, the charge and discharge probe group 123 is provided with a plurality of probes, and the probe setting position corresponds to the position of the lifting mechanism 121, which is used to contact the battery 600 electrode when the lifting mechanism 121 rises to its position, thereby forming a charge and discharge circuit between the battery 600 electrode and the external charge and discharge device to achieve charge and discharge.

[0066] It can be understood that in order to facilitate the positioning of the battery 600, a positioning portion 122 for accommodating the battery 600 is provided on the upper portion of the lifting mechanism 121. The positioning portion 122 can directly position the battery 600, or position the tray 700 of the battery 600, thereby ensuring that after the battery 600 is placed in the lifting mechanism 121, it can maintain a specific posture and be in a specific position.

[0067] Specifically, the lifting mechanism 121 in this embodiment specifically includes a lifting cylinder 1211 and a lifting platform 1212. The lifting cylinder 1211 is arranged at the bottom of the sealed chamber 110, and the extension direction of the lifting cylinder 1211 is vertically upward. At the same time, the bottom of the lifting platform 1212 is connected to the telescopic rod of the lifting cylinder 1211, so as to be linked and synchronized with the telescopic rod of the lifting cylinder 1211.

[0068] The working principle of the lifting mechanism 121 of the embodiment of the utility model is as follows: in the charge and discharge preparation stage, the lifting mechanism 121 descends and the battery 600 or the battery tray 700 with the battery 600 is placed. Specifically, the lifting platform 1212 is driven by the lifting cylinder 1211 to descend. After the battery 600 is placed in place, the lifting mechanism 121 rises, and the electrodes of the battery 600 are electrically connected with the charge and discharge probe group 123 above, completing the charge and discharge preparation.

[0069] By means of the lifting mechanism 121 , the placement and docking of the battery 600 can be completed quickly and efficiently, thereby improving the efficiency of the charging and discharging preparation process of the battery 600 .

[0070] Embodiment 3

[0071] This embodiment discloses a battery charging and discharging environment temperature control system. Figure 2 and Figure 3 , Figure 2 The battery charging and discharging environment temperature control system of this embodiment is shown in FIG. Figure 3 The structure of part A of the battery charging and discharging environment temperature control system of this embodiment is enlarged and schematically shown, including: a plurality of battery charging and discharging storage locations 100 , an air intake module 200 and an air discharge module 300 .

[0072] The battery charging and discharging storage locations 100 are usually distributed in the production environment in a horizontal array and vertical stacking manner, thereby improving the space utilization of the production environment. The specific charging and discharging storage locations adopt the structure disclosed in the above embodiment of the utility model in terms of structure.

[0073] In addition, in order to ensure temperature control in the production environment, it is necessary to form an air circulation channel through the cooperation of the air intake module 200 and the air discharge module 300.

[0074] Specifically, the air intake module 200 includes an output end connected to the air intake channel 131 of each battery charging and discharging storage location 100 and an input end connected to the high-pressure air source. The air release module 300 includes an input end connected to the air outlet channel 132 of each battery charging and discharging storage location 100 and an output end connected to the low-pressure air source.

[0075] At the gas path level, each battery charging and discharging storage position 100 is preferably in a parallel relationship, that is, the air intake module 200 and the air discharge module 300 are respectively provided with a main gas path, and all the battery charging and discharging storage positions 100 are directly connected to this main gas path, so as to avoid heat exchange caused by gas circulation between each charging and discharging storage position as much as possible.

[0076] In this embodiment, the high-pressure air source connected to the air intake module 200 is formed by the fan 800, and the external air is drawn into the system by the fan 800 to form a high pressure higher than the atmospheric pressure. It can be understood that when a higher air pressure is required, the air pressure of the external high-pressure air source can also be further increased by the fan 800. The low-pressure air source connected to the air discharge module 300 is equal to or lower than the atmospheric pressure. Under the action of the fan 800, the air enters the system from the air intake module 200 and then is exhausted from the air discharge module 300.

[0077] The battery charging and discharging environment temperature control system of this embodiment has the following specific working process: the battery 600 and the tray are placed in the sealed chamber 110 → the battery 600 is lifted into place by the lifting mechanism 121, and the battery 600 electrodes are in contact with the charging and discharging probe group 123 → the chamber door 112 is closed → the sealed chamber 110 is evacuated → the battery 600 is charged and discharged → the sealed chamber 110 is broken from vacuum → the battery 600 is lowered into place, and the battery 600 electrodes are separated from the charging and discharging probe group 123 → the air intake module 200 and the air release module 300 are turned on, and circulating air flows through the sealed chamber 110, and the battery 600 is cooled down → the chamber door 112 is opened → the battery 600 and the tray are taken out of the chamber 111.

[0078] In the above process, the battery charging and discharging environment temperature control system of the utility model avoids the heat of the battery 600 from being conducted to the outside by vacuuming during the charging and discharging process of the battery 600, thereby effectively reducing the heat exchange inside the production site and reducing the energy consumption caused by cooling the inside of the production site. At the same time, the air intake module 200 and the air discharge module 300 directly exchange air in the battery charging and discharging storage position 100, and directly discharge the high-temperature gas to the outside, so as to achieve efficient cooling of the battery 600 while avoiding the phenomenon of temperature difference between storage positions caused by the heat in the production environment gathering to the upper battery charging and discharging storage position 100, thereby improving the consistency of the temperature of all battery charging and discharging storage positions 100 in the production site, thereby ensuring the consistency of the charging and discharging capacity of the battery 600.

[0079] In addition, in order to ensure the cleanliness of the air entering the system, in some preferred embodiments, an air filter module 400 may be provided, which is connected between the air intake module 200 and the external air source. The air passing through the air intake module 200 is filtered to prevent dust and other components in the air from contaminating the air path inside the system.

[0080] For details, please refer to Figure 2 and Figure 3 The air filter module 400 includes a primary filter module 410 and a final filter module 420 which are sequentially connected in series along the air intake direction. The primary filter module 410 and / or the final filter module 420 include at least one air filter layer. Preferably, the primary filter module 410 is provided with two air filter layers, and the final filter module 420 is provided with one air filter layer. After passing through the three air filter layers, the external air has a higher cleanliness to avoid contaminating the air path inside the system. It is understandable that the filtering capacity of the air filter module 400 can be adjusted according to actual needs.

[0081] In addition, since the air filter module 400 is mainly used to construct a filter barrier between the air intake module 200 and the external air source, it is ensured that the air entering the air intake module 200 is clean. Therefore, it can be understood that the air filter module 400 only needs to be connected between the air intake module 200 and the external air source, and the external air source can be a pressurized high-pressure air source or an unpressurized normal-pressure air source. Based on this, the fan 800 can be arranged in the air path upstream or downstream of the air path of the air filter module 400 according to actual needs. When the fan 800 is arranged in the air path upstream of the air filter module 400, the airflow entering the air filter module 400 is a high-pressure airflow; when the fan 800 is arranged in the air path downstream of the air filter module 400, the airflow entering the air filter module 400 is a normal-pressure airflow.

[0082] Embodiment 4

[0083] The battery charging and discharging environment temperature control system of this embodiment is different from that of the third embodiment in that this embodiment further optimizes the internal circulation function.

[0084] Please refer to Figure 4 and Figure 5 , Figure 4 The battery charging and discharging environment temperature control system of this embodiment is shown in FIG. Figure 5The structure of part B of the battery charging and discharging environment temperature control system of this embodiment is enlarged and schematically shown. An internal circulation channel 500 and a circulation fan 510 are also provided between the input end of the air release module 300 and the input end of the air intake module 200. The input end of the internal circulation channel 500 is connected to the input end of the air release module 300, and the output end of the internal circulation channel 500 is connected to the input end of the air intake module 200. Under the action of the internal circulation channel 500 and the circulation fan 510, a part of the airflow can be reintroduced into the air intake module 200, so that the airflow is recirculated. This structure can effectively improve the cooling effect of the unit volume of airflow and improve the utilization efficiency of the high-pressure air source.

[0085] At the same time, in order to control the ventilation volume of the circulating airflow, the air release module 300 also includes a temperature sensor 320 and an air volume control valve 310. The temperature sensor 320 is used to detect the temperature inside the input end of the air release module 300. The air volume control valve 310 is connected in series to the output end of the air release module 300. The air volume control valve 310 can control the amount of air discharged outward from the air release module 300. Generally, the amount of air discharged outward should be related to the temperature of the circulating airflow in the system to ensure the cooling capacity of the system. Therefore, the opening and closing degree of the air volume control valve 310 responds to the output signal of the temperature sensor 320. In a feasible implementation process, the temperature sensor 320 outputs different signals to the external controller according to the temperature of the circulating airflow in the current system, and the external controller controls the opening and closing degree of the air volume control valve 310 according to the received signal.

[0086] In this embodiment, the air volume control valve 310 is a one-way proportional air valve, which is a one-way valve that discharges a certain proportion of high-temperature air back to the atmosphere, and the discharge ratio can be controlled between 20% and 100%. When the external controller senses that the temperature of the circulating air flow inside the system increases, it controls the air volume control valve 310 to increase the opening ratio, so that the exhaust air flow rate increases.

[0087] At the same time, in order to ensure the pressure balance in the system, the total air intake from the external high-pressure air source into the system is preferably consistent with the total air output from the system to the external low-pressure air source.

[0088] Specifically, in order to further optimize the internal circulation airflow, in some embodiments, the output end of the internal circulation channel 500 can also be connected to the final filter module 420.

[0089] At this time, the final filter module 420 includes a first input end, a second input end and an output end, wherein the first input end is connected to the input end of the degassing module 300 , the second input end is connected to the output end of the primary filter module 410 , and the output end of the final filter module 420 is connected to the intake module 200 .

[0090] In addition, the inner circulation channel 500 and the circulation fan 510 are arranged between the input end of the degassing module 300 and the first input end of the final filter module 420. The input end of the inner circulation channel 500 is connected to the input end of the degassing module 300, and the output end of the inner circulation channel 500 is connected to the first input end of the final filter module 420 through the circulation fan 510.

[0091] Based on the above structure, since the external airflow passes through the primary filter module 410 and the final filter module 420 before entering the interior, the gas cleanliness is relatively high. When performing internal circulation, it does not need to pass through the primary filter module 410 again, but directly passes through the final filter module 420 before entering the circulation. The resistance of the circulating airflow can be reduced, and the circulation speed can be increased. In addition, the newly entered external airflow can be fully mixed in the final filter module 420, thereby reducing the temperature of the internal circulating airflow.

[0092] The above embodiments are only preferred embodiments of the present invention and are intended to further describe the technical solutions of the present invention in detail. However, the above descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. The protection scope and implementation methods of the present invention are not limited thereto. Any changes, combinations, deletions, replacements or modifications that do not deviate from the spirit and principles of the present invention shall be included in the protection scope of the present invention.
