Description

Technical Field

[0001] The utility model relates to the field of new energy battery management systems, and in particular to a liquid temperature control management system, a base station integrated cabinet and a server cabinet. Background Art

[0002] In the industry chain related to new energy batteries, the application of lithium batteries and lead-acid batteries in communication room scenarios is a technical issue of concern in the industry. At present, the demand for energy storage batteries in communication base stations is growing steadily, and the shipment volume of lithium-ion batteries in the industry has increased significantly; this phenomenon shows that lithium batteries, as a new energy battery technology, will continue to maintain growth momentum in the next few years.

[0003] However, lithium batteries themselves inevitably have the risk of spontaneous combustion, which is caused by the thermal runaway phenomenon inside them. The potential risks make communication operators generally cautious about the solution of placing lithium batteries in communication rooms. In contrast, although lead-acid batteries have problems such as short cycle life and low energy density, they will not spontaneously combust and explode, and have advantages in safety. Therefore, new energy batteries such as lithium batteries gradually replace traditional batteries, and it is necessary to overcome the defects of new energy batteries themselves.

[0004] In summary, the industry needs to design a solution for lithium batteries that can effectively prevent the battery cells from overheating and entering a thermal runaway state, thereby facilitating the application and promotion of lithium batteries in communication cabinet scenarios. Utility Model Content

[0005] The technical problem to be solved by the present invention is: how to design a solution for lithium batteries that can effectively prevent the battery cells from overheating and entering a thermal runaway state, thereby overcoming the shortcoming of lithium batteries being prone to spontaneous combustion, so that the lithium batteries managed by the system can be safely placed in a communication cabinet or a computer room.

[0006] In the first aspect, the utility model proposes a liquid temperature control management system, which includes: a comprehensive management unit, a detection unit, a control unit, and an alarm unit, wherein the comprehensive management unit is connected to the detection unit, the comprehensive management unit is connected to the control unit, and the comprehensive management unit is connected to the alarm unit; the detection unit is connected to multiple in-box ambient temperature sensors, multiple battery cell temperature sensors, and in-box liquid level sensors of the battery box, the control unit is connected to multiple liquid pump current sensors and liquid pump voltage sensors, and the alarm unit is connected to multiple liquid pump control relays. Among them, the battery box is equivalent to a battery cell compartment or a battery cell compartment. In one embodiment, the control unit is connected to multiple liquid pump current sensors and liquid pump voltage sensors in the liquid box, and the alarm unit is connected to multiple liquid pump control relays.

[0007] In the above scheme, the liquid temperature control management system belongs to the module-level liquid temperature control battery safety management system. Due to the module-level liquid temperature control, a series of functions must be realized, such as liquid flow management, battery temperature management, liquid temperature management, liquid circulation management, and automatic module liquid emptying management, as well as cutting off the external power connection of the module battery, and issuing an abnormally high temperature alarm for the battery. Therefore, it is necessary to design a battery safety management system based on module-level liquid temperature control, that is, a liquid temperature control management system. The system is as follows Figure 1 As shown, one embodiment of the liquid temperature control management system is as follows Figure 2 As shown, the correspondence between the nouns in the embodiment of the present invention and the nouns in the figure is shown in the reference numerals, which is known to those skilled in the art.

[0008] Its further technical solution is that the liquid temperature control management system also includes a lithium battery box body module, the lithium battery box body module includes a battery box and a liquid box connected to each other, a communication pipeline for liquid circulation is provided between the battery box and the liquid box, and multiple battery cells are installed in the battery box. In one embodiment, the lithium battery box body module includes a battery box for placing battery cells and a liquid box for storing temperature control liquid, which are connected to each other. A communication pipeline is provided between the battery box and the liquid box, and multiple battery cells corresponding to the battery box are installed in the battery box.

[0009] In the above solution, in order to achieve the adaptation of the main module and the cabinet, engineers will integrate the battery box and the liquid box in a building block-like stacking. The integrated layout can be divided into two types from the architectural perspective. The first is that the battery box is on the top and the liquid box is on the bottom, and the second is that the liquid box is on the top and the battery box is on the bottom.

[0010] Furthermore, the composition mode of the lithium battery box body module can be divided into a module-separate type and a box-centralized type in terms of appearance; wherein the module-separate type means that the battery box and the liquid box are directly stacked, and the appearance is two boxes, and the box-centralized type means that the battery box and the liquid box are placed in a large box, and the appearance is a large box. The schematic diagrams of these two appearances are as follows Figure 3 The side view of the lithium battery and the liquid box is the side view of the battery box and the liquid box. The interconnecting pipeline for liquid circulation is limited only between the battery box and the liquid box. The purpose is that all liquid-related components of the lithium battery box total module do not need to involve the cabinet frame during operation, nor do they need to be installed and fixed on the cabinet frame.

[0011] The internal ambient temperature sensor corresponding to the battery box is connected to the battery box and is used to detect the air temperature inside the battery box. The air temperature inside the box corresponds to the temperature of the environment in which the battery cell is located, and is used to provide data input for the life maintenance management of the battery cell in the battery box.

[0012] A further technical solution is that the battery cell temperature sensor is connected to the battery cell and is used to detect the battery cell pole temperature of the battery cell. The battery cell pole temperature is used to represent the internal temperature of the battery cell and is used to provide data input for the management of abnormal increase in the internal temperature of the battery cell.

[0013] A further technical solution is that a liquid level sensor corresponding to the battery box is connected to the battery box to detect the liquid height when the liquid in the battery box immerses the battery cells, thereby ensuring that the battery cells are completely immersed in the liquid in the battery box.

[0014] A further technical solution is that the control unit is used to control the start and stop of the liquid pump in the liquid box, to control the on and off of the connection between the battery cell and the outside, and to control the circulation direction of the liquid in the module. In the above solution, because the liquid and the liquid pump are usually not in the battery box, but in the liquid box, such as Figure 4 and Figure 5 As shown, the liquid pump is driven by liquid to enter the battery box to immerse the battery cells and circulate to take away the heat of the battery cells; further, when the temperature of the battery cells rises abnormally, the external power supply of the battery cells is cut off while the liquid is immersed to reduce the heat generated by the battery cells; in one embodiment, the liquid circulation process of the lithium battery box body module includes forward flow and reverse flow, a total of two modes, the forward flow corresponds to the continuous injection of liquid into the battery box, and the reverse flow corresponds to the continuous emptying of the liquid in the battery box.

[0015] A further technical solution is that the alarm unit is used to realize the battery box temperature over-high alarm and the battery cell temperature over-high alarm, to realize the box environment temperature sensor failure alarm and the battery cell temperature sensor alarm, and also to realize the liquid pump failure alarm.

[0016] In the second aspect, the present application proposes a base station integrated cabinet, which includes the liquid temperature control management system as described in the first aspect, and the base station integrated cabinet also includes: a power distribution unit, a base station photovoltaic module, a rectifier module, a transmission frame, and a BBU device. The power distribution unit is connected to the base station photovoltaic module, the base station photovoltaic module is connected to the rectifier module, the rectifier module is connected to the transmission frame, the transmission frame is connected to the BBU device, and the BBU device is connected to at least three lithium battery box total modules, and at least three lithium battery box total modules are all connected to the liquid temperature control management system.

[0017] In the third aspect, the present application proposes a server cabinet, the server cabinet includes the liquid temperature control management system as described in the first aspect, the server cabinet also includes: a cabinet photovoltaic module, an uninterruptible power supply module, a photovoltaic transmission device, a router device, a cabinet server, the cabinet photovoltaic module is connected to the uninterruptible power supply module, the photovoltaic transmission device is connected to the router device, the router device is connected to the cabinet server, the uninterruptible power supply module is connected to at least four lithium battery box modules, and at least four lithium battery box modules are connected to the photovoltaic transmission device. Among them, the server cabinet and the base station integrated cabinet, by definition, both belong to the classification used for cabinets; the base station integrated cabinet and the server cabinet embedded with a module-level liquid temperature control lithium battery box module are as follows Figure 7 as well as Figure 8 .

[0018] In the above scheme, the cells in the battery box adopt a working mode combining the normal air environment and the overheated liquid environment. Specifically, the battery box contains a large number of cells, a large number of sensors for collecting temperature parameters, sensors for collecting voltage parameters and connecting conductors. The cooling and temperature control liquid does not enter the lithium battery box module at ordinary times, but is stored in the liquid box module; therefore, when performing daily maintenance or repairs on the cells, wires, temperature probes, voltage probes, BMS battery management system, etc. of the lithium battery box module, engineers do not need to touch the liquid in the battery box.

[0019] Furthermore, the battery cell temperature sensor is exposed to the air environment and can detect the actual changes in the internal temperature of the battery cell early. On the contrary, the battery cell and the ambient temperature sensor in the box are in a liquid immersion environment. Since the liquid takes away heat, the battery cell temperature sensor cannot accurately capture the true value of the battery cell temperature. Often the sensor test temperature is lower than the battery cell temperature, and there is a significant time lag effect.

[0020] Furthermore, when the battery cell temperature sensor in the air environment can detect that the battery cell temperature reaches a preset threshold in the first time, it will promptly trigger the liquid pump to drive the liquid from the liquid tank into the battery box, thereby achieving liquid immersion and liquid circulation, controlling the battery cell temperature to always be within a safe range, and issuing an alarm for battery cell abnormalities through the alarm unit; when the temperature control operation of the liquid-immersed battery cell is completed, the liquid in the battery box should be able to automatically flow back into the liquid box module.

[0021] In the prior art, system-level and cabinet-level liquid temperature control solutions have certain technical defects: first, the lithium battery cabinet must be customized, and the liquid cooling pipes and liquid drive devices are fixed on the cabinet; second, the existence of the liquid pipelines in and out of the lithium battery cabinet makes it impossible to install communication network equipment and communication cables in the lithium battery cabinet, and it is also impossible to flexibly add or subtract power distribution equipment. The above technical problems have resulted in this lithium battery energy storage solution being unable to be quickly and friendly promoted and applied in a large number of small and medium-sized computer rooms, base station scenarios, and integrated scenarios of communication operators, and the liquid temperature control management system described in the utility model solves the above problems.

[0022] In the prior art, the liquid pipes and oil storage tanks of the cabinet's integrated liquid cooling temperature control system are all preset and fixed in the cabinet, and the lithium battery box total module and the cabinet form a tightly coupled whole. During the product design stage, it is necessary to clarify the number of lithium battery box total modules that need to be deployed in the cabinet, and arrange the corresponding number of liquid pipes, electric valves and the fixed positions of these things in the cabinet. In addition, during the product design stage, it is necessary to clarify the spatial position of the lithium battery box total module installed in the cabinet, that is, the u position of the lithium battery box total module. The number and installation position of the lithium battery box total module cannot be flexibly changed as needed, and the lithium battery box total module cannot be installed in other types of cabinets, which brings a lot of inconvenience to the application of lithium batteries.

[0023] The present application realizes the decoupling of the lithium battery box total module and the cabinet through a module-level liquid cooling temperature control solution, and has a high degree of flexibility: first, the number of lithium battery box total modules can be changed as needed; second, the installation position of the lithium battery box total module can be changed as needed; third, the lithium battery box total module can be embedded in various types of cabinets as needed.

[0024] To sum up, new energy batteries such as lithium batteries are gradually replacing traditional batteries, and the defects of new energy batteries themselves need to be overcome; the solution described in this application can effectively prevent the battery cells from overheating and entering a thermal runaway state, thereby overcoming the shortcoming of lithium batteries being prone to spontaneous combustion, so that the lithium batteries managed by the system can be safely placed in communication cabinets or computer rooms.
