[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] Example:

[0040] Reference Figure 1 - Fig.11 A sodium ion battery energy storage module includes a casing 1 and a cover plate 2, wherein the cover plate 2 is plugged and installed on the upper part of the casing 1, a sodium ion battery column 7 is placed between the casing 1 and the cover plate 2, and a heating component 5 is also included, the heating component 5 is plugged and placed inside the casing 1, and the sodium ion battery column 7 is placed in the heating component 5, wherein a heating flow channel through which a heating medium can pass is arranged inside the heating component 5, and the sodium ion battery column 7 receives heat from the heating flow channel to perform independent battery heating action.

[0041] The above-mentioned sodium ion battery energy storage module realizes precise heating of each independent sodium ion battery column 7 through the heating flow channel arranged inside the heating component 5.

[0042] Specifically, the heating component 5 is inserted and placed inside the casing 1 to ensure its close contact with the sodium ion battery column 7. The heating medium circulates through the heating flow channel. The heating medium is heated by the external heating source. The heat medium in the flow channel is in direct contact with the sodium ion battery column 7, and the heat is transferred to the battery column through heat conduction, so that its temperature rises rapidly to a preset temperature range. The design of the heating flow channel ensures uniform distribution of heat and avoids unnecessary loss of heat to non-target components in traditional heating methods. At the same time, since the heating component 5 directly contacts the battery column, the heat transfer path through the casing 1 and the insulating material is reduced, the heat loss is reduced, and the heating efficiency is improved. It can not only quickly increase the battery temperature to a suitable operating temperature, but also effectively prevent the problem of discharge power reduction in a low temperature environment, thereby ensuring battery performance and safety.

[0043] In order to realize the series-parallel use of multiple modules, preferably, a conductive seat 3 is fixedly connected to the upper part of the battery plate, and two conductive seats 3 are provided, and the two conductive seats 3 are respectively a positive electrode seat and a negative electrode seat.

[0044] In order to realize the serial and parallel use of multiple sodium ion battery columns 7, further, the upper and lower parts of the sodium ion battery column 7 are respectively pressed and contacted with the cover plate 2 and the housing 1 for electrical connection, the cover plate 2 is electrically connected to the housing 1, and the cover plate 2 is electrically connected to the electric socket. In order to realize the diversion of the heating component 5, further, the heating component 5 is provided with multiple, and the array of multiple heating components 5 is plugged and installed inside the housing 1. The two sides of each heating component 5 are fixedly installed with diversion components 6 for connecting the heating pipeline. The two sides of the upper part of the cover plate 2 are provided with pipeline access ports 4, and the pipeline access ports 4 are arranged corresponding to the input ports of the diversion component 6.

[0045] In order to realize the series and parallel use of multiple sodium ion battery columns 7, the upper and lower parts of the battery columns are respectively pressed and electrically connected with the cover plate 2 and the casing 1, ensuring the electrical connection between the battery columns. The voltage can be increased by series connection, and the capacity can be increased by parallel connection. The cover plate 2 is electrically connected to the casing 1, and is connected to an external power supply through the electric socket on the upper part of the cover plate 2, realizing the external connection of the power supply, which not only simplifies the assembly process of the battery module, but also realizes reliable electrical connection through pressing contact, ensuring the safety and stability of the battery system.

[0046] In order to achieve the diversion of the heating component 5, the heating component 5 is designed to be multiple and plugged into the casing 1 in the form of an array, allowing each heating component 5 to work independently, ensuring the precise heating of each sodium ion battery column 7, and each heating component 5 is fixedly installed with diversion components 6 for connecting heating pipes on both sides. These diversion components 6 are responsible for introducing the heating medium into the flow channel inside the heating component 5. Pipe access ports 4 are provided on both sides of the upper part of the cover plate 2. These access ports are arranged corresponding to the input ports of the diversion components 6, allowing external heating medium to enter the module through the pipe access ports 4, circulate through the flow channel of the heating component 5, and then be discharged from the pipe access ports 4 on the other side, which not only realizes the external circulation of the heating medium, but also ensures the efficient utilization and uniform distribution of heat through the array arrangement and the precise design of the diversion components 6, and avoids the unnecessary loss of heat to non-target components.

[0047] Through the above content, not only the external connection of power supply and heating medium is realized, which improves the flexibility and scalability of the system, but also the stability and safety of battery performance are enhanced through precise thermal management and electrical connection.

[0048] In order to achieve heating of the sodium ion battery column 7, further, the heating assembly 5 includes a heating plate 501, a heating chamber 503 is provided inside the heating plate 501, a heat-conducting tube 504 is fixedly connected inside the heating plate 501, the heat-conducting tube 504 is located in the middle of the heating chamber 503, and the sodium ion battery column 7 is inserted and placed inside the heat-conducting tube 504. In order to achieve uniform heating of the sodium ion battery column 7, further, a diverter plate 506 is fixedly connected inside the heating plate 501, and a plurality of diverter plates 506 are provided, and a plurality of diverter plates 506 are arranged in a longitudinal layered array inside the heating plate 501, and a side of the diverter plate 506 away from the inner wall of the heating plate 501 is fixedly connected to the outer wall of the heat-conducting tube 504, and a plurality of diverter plates 506 separate the heating chamber 503 to perform a heating medium diversion action.

[0049] The heating assembly 5 is mainly composed of a heating plate 501, and a heating cavity 503 is provided inside the heating plate 501 for accommodating a heating medium. The design of the heating cavity 503 ensures the flow of the heating medium in the plate and provides a heating environment. A heat-conducting tube 504 is fixedly connected inside the heating plate 501. The heat-conducting tube 504 is located in the middle of the heating cavity 503 and plays a role in heat conduction. The sodium-ion battery column 7 is inserted and placed inside the heat-conducting tube 504, ensuring close contact between the battery column and the heat-conducting tube 504. The high thermal conductivity material of the heat-conducting tube 504, such as copper or aluminum alloy, enables the heat of the heating medium to be quickly and evenly transferred to the battery column.

[0050] In order to further achieve uniform heating of the sodium ion battery column 7, a plurality of diverter plates 506 are fixedly connected inside the heating plate 501. These diverter plates 506 are arranged in the form of a longitudinal layered array inside the heating plate 501. The function of the diverter plates 506 is to divide the heating chamber 503 into a plurality of independent flow channels, so that the heating medium is evenly diverted during the flow process, reducing the concentration and uneven distribution of heat in the flow channel. The side of each diverter plate 506 away from the inner wall of the heating plate 501 is fixedly connected to the outer wall of the heat-conducting tube 504, ensuring the heat conduction path between the heat-conducting tube 504 and the diverter plate 506.

[0051] After the heating medium is heated by an external heating source, it enters the heating chamber 503 and flows through the flow channel separated by the diverter plate 506. Due to the existence of the diverter plate 506, the heating medium is dispersed during the flow process, avoiding the heat concentration in a certain area. The heat medium is in direct contact with the heat-conducting tube 504, and the heat is transferred to the sodium-ion battery column 7 through the heat-conducting tube 504. The combined design of the heat-conducting tube 504 and the diverter plate 506 ensures the uniform distribution and conduction of heat, avoids the formation of hot spots, and realizes the uniform heating of the battery column. By controlling the temperature and flow of the heating medium, the temperature of the sodium-ion battery column 7 can be accurately adjusted to ensure that it is within the optimal operating temperature range, thereby preventing battery problems in a low temperature environment.

[0052] In order to achieve communication with the external heating medium, the flow guide assembly 6 further includes a connection seat 601, and a screw groove for connecting the heating medium transmission pipeline is provided on the upper part of the connection seat 601. Two connection seats 601 are provided, and the two connection seats 601 are respectively fixed on the upper parts of both sides of the heating plate 501. In order to achieve uniform discharge, diversion and flow diversion, further, a flow guide plate 602 is fixedly connected to the lower part of each connection seat 601, one side of the flow guide plate 602 is in contact with the heating plate 501, and a side of the flow guide plate 602 close to the heating plate 501 is fixedly connected to a plurality of diversion pipes 603, and an air inlet 502 and an air outlet 507 are respectively provided on both sides of the heating plate 501, and a plurality of diversion pipes 603 on both sides are respectively plugged into the air inlet 502 and the air outlet 507.

[0053] The heating medium enters the guide assembly 6 through the screw grooves on the two connecting seats 601 connected to the upper parts of both sides of the heating plate 501. A guide plate 602 is fixed at the lower part of the connecting seat 601. The guide plate 602 fits tightly with the heating plate 501 to ensure effective guidance of the heating medium. Several shunt pipes 603 fixedly connected to the guide plate 602 disperse the heating medium and flow it into the heating chamber 503 through the air inlet 502 on one side of the heating plate 501. In the heating chamber 503, heat is transferred to the sodium ion battery column 7 through the heat conduction tube 504. The heating medium is evenly distributed by the shunt pipe 603 during the flow process to ensure uniform distribution of heat. When flowing out, it passes through the air outlet 507 on the other side of the heating plate 501 to form a circulating flow path, thereby achieving uniform heating of the battery column. By accurately controlling the temperature and flow of the heating medium, it is ensured that the battery column is within the optimal operating temperature range, the service life of the battery is extended, and the safety and stability of the system are improved.

[0054] In order to further heat the sodium ion battery column 7 in extremely cold weather, a branch channel 606 is further provided inside the connecting seat 601, and the connecting seat 601 is connected with the gas channel of the cover plate 2 through the branch channel 606. A thermal telescopic member 604 is fixedly installed inside the branch channel 606, and a plug 605 is fixedly installed on the moving part of the thermal telescopic member 604. The plug 605 movably blocks the branch channel 606, and a spiral channel 505 is provided inside the main body of the heat conductive tube 504, and the spiral channel 505 is respectively connected and connected with the cover plate 2 and the casing 1. In order to realize the control of the plug 605 to block the branch channel 606 according to the change of air temperature, the thermal telescopic component 604 further includes a liquid storage tube 6041 for storing thermal expansion and contraction medium, a telescopic rod 6042 is slidably installed on one side of the liquid storage tube 6041, the end of the telescopic rod 6042 is screwed to the plug 605, a knob 6044 is rotatably installed on one side of the liquid storage tube 6041, a screw 6045 is fixedly connected to one side of the knob 6044, a piston plate 6043 is screwed to the outside of the screw 6045, and the piston plate 6043 is slidably installed in the inner cavity of the liquid storage tube 6041.

[0055] Extreme Cold Weather Heating Mode:

[0056] In extremely cold weather, in order to further heat the sodium ion battery column 7, the branch channel 606 provided inside the connection seat 601 is connected with the gas channel of the cover plate 2, thereby realizing an additional heating path.

[0057] When the ambient temperature drops to an extremely low temperature, the thermal expansion and contraction medium stored in the liquid storage tube 6041 contracts due to the low temperature, resulting in a decrease in the pressure in the liquid storage tube 6041. Affected by this, the telescopic rod 6042 fixed on one side of the liquid storage tube 6041 moves under the tension of the contraction of the medium, driving the plug 605 to disengage from the branch channel 606, opening the connection with the gas channel of the cover plate 2. At the same time, through the rotation of the knob 6044, the screw 6045 drives the piston plate 6043 to slide in the liquid storage tube 6041, further adjusting the pressure of the medium and controlling the movement of the plug 605. At this time, the heating medium from the outside can enter the cover through the branch channel 606. The gas channel of plate 2 then enters the interior of the heat-conducting tube 504 through the spiral channel 505. The design of the spiral channel 505 ensures the maximum contact area between the heating medium and the heat-conducting tube 504 during the flow process, thereby improving the efficiency of heat transfer. The heating medium heats the sodium-ion battery column 7 in the heat-conducting tube 504, thereby ensuring that the battery can maintain an optimal operating temperature at extremely low temperatures, thereby preventing performance degradation or safety hazards in a low-temperature environment. This not only achieves additional heating of the battery, but also dynamically adjusts the flow path of the heating medium according to changes in ambient temperature through automatic control of the thermal telescopic member 604, thereby ensuring the heating efficiency and stability of the battery performance.

[0058] Recovery mode after temperature rises:

[0059] When the ambient temperature starts to rise, the thermo-sensitive stretchable element 604 will enter the recovery mode.

[0060] As the temperature rises, the thermal expansion and contraction medium in the liquid storage tube 6041 begins to expand, pushing the telescopic rod 6042 to move outward, driving the plug 605 to move toward the branch channel 606, and finally the plug 605 blocks the branch channel 606 again, cutting off the connection with the gas channel of the cover plate 2, and stopping the additional heating path. At this time, the flow path of the heating medium only enters the heating chamber 503 through the shunt pipe 603 inside the heating plate 501 to heat the sodium ion battery column 7. At the same time, the rotation of the knob 6044 can adjust the rotation of the screw 6045, and the piston plate 6043 is driven by the screw 6045 to slide in the liquid storage tube 6041, further controlling the pressure of the medium and ensuring the complete blocking of the plug 605. Through the automatic adjustment of the thermal telescopic member 604, the flow of the heating medium is controlled according to the temperature change, avoiding unnecessary heat consumption in a non-extreme low temperature environment, and improving the overall energy efficiency of the system.

[0061] In addition, the design of the spiral channel 505 ensures that the battery column can be heated evenly under any temperature conditions, thereby extending the service life of the battery and enhancing the safety and stability of the system.

[0062] In the present invention, accurate heating of each independent sodium ion battery column 7 is achieved by the heating flow channel arranged inside the heating component 5. Specifically, the heating component 5 is placed by plugging inside the casing 1 to ensure its close contact with the sodium ion battery column 7. The heating medium circulates through the heating flow channel, and the heating medium is heated under the heating of the external heating source. The heat medium in the flow channel is in direct contact with the sodium ion battery column 7, and the heat is transferred to the battery column through heat conduction, so that its temperature rises rapidly to a preset temperature range. The design of the heating flow channel ensures uniform distribution of heat and avoids unnecessary loss of heat to non-target components in traditional heating methods. At the same time, since the heating component 5 directly contacts the battery column, the heat transfer path through the casing 1 and the insulating material is reduced, the heat loss is reduced, and the heating efficiency is improved. Not only can the battery temperature be quickly raised to a suitable operating temperature, but also the problem of discharge power reduction can be effectively prevented in a low temperature environment, thereby ensuring battery performance and safety.
