Description

Technical Field

[0001] The present invention relates to the technical field of lithium iron phosphate batteries, and in particular to a digitally controlled energy conversion type lithium iron phosphate battery for information communication. Background Art

[0002] Existing signal base stations are equipped with energy conversion lithium iron phosphate batteries, so that when the voltage of the power grid that supplies power to the signal base station fluctuates, the lithium iron phosphate batteries can promptly replace the power grid to supply power to the signal base station, thereby maintaining the stable use of the signal base station. The energy conversion lithium iron phosphate battery can intelligently adjust the charging and discharging methods under the control of the control terminal to improve the energy utilization rate. Existing lithium iron phosphate batteries are generally composed of multiple groups of battery cells, and the outer side of the battery cell is mostly rubber or heat-resistant plastic shell. When the battery cell is charged and discharged at a high frequency, the heat generated by the battery cell will also increase. At this time, the battery cell is very likely to expand slightly, and the outer shell of the battery cell It is also easy to melt due to high temperature and stick to surrounding objects. In order to save space, the existing lithium iron phosphate battery has a relatively compact arrangement of battery cells. The existing lithium iron phosphate battery only detects the temperature of the battery cell through sensors, and cannot detect whether the battery cell has slightly expanded. When the temperature of the battery cell rises, it does not necessarily lead to battery cell expansion, shell melting, etc. Therefore, when the existing temperature sensor is used to detect the expansion of the battery cell, the error is large, and the expansion of the battery cell is an irreversible reaction.

DETAILED DESCRIPTION

[0019] The following embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with the technology may modify or change the embodiments of the present invention without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed by the present invention are still within the scope of protection of the present invention.

[0020] Example 1: The battery cells in the existing lithium iron phosphate battery are arranged relatively compactly, resulting in poor heat dissipation inside the battery cells. When the battery cell charging or discharging efficiency is high, the temperature of the battery cell will gradually increase. If the outer shell of the battery cell melts or expands slightly at high temperature, it will affect the safety of the battery cell. The existing device can only indirectly detect the battery cell through a temperature sensor, but there is no necessary connection between the temperature of the battery and whether it expands. Therefore, this detection method results in poor detection accuracy of battery cell expansion, which can easily cause thermal runaway of the expanded battery cell during operation, and then cause accidents such as battery cell explosion.

[0021] In view of the above problems, the present invention proposes a digitally controlled energy conversion lithium iron phosphate battery for information communication. Figure 1-Figure 7, including a shell 1, a control terminal is arranged on the front side of the shell 1, a battery compartment 2 symmetrically distributed on the left and right is fixedly connected in the shell 1, an end cover 3 is fixedly connected to the upper part of the battery compartment 2, a plurality of groups of heat dissipation baffles 4 evenly distributed front and back are fixedly connected in the battery compartment 2, each group includes heat dissipation baffles 4 evenly distributed front and back, and the upper sides of the heat dissipation baffles 4 of the same group are commonly fixedly connected with battery units 5 evenly distributed and electrically connected to the control terminal, the heat dissipation baffles 4 are used to support the battery units 5 on the upper side thereof, so that the air can dissipate heat to the lower sides of adjacent battery units 5, two first electric push rods 6 symmetrically distributed on the left and right and electrically connected to the control terminal are fixedly connected near the heat dissipation baffles 4 of the adjacent groups in the battery compartment 2, the telescopic end of the first electric push rod 6 is limitedly slidably connected with a reinforced cooling member, the reinforced cooling member is used to separate the battery units 5 of the same group, and provide sufficient cooling for the compactly structured battery units 5, and the reinforced cooling member includes a bottom fin group 7 fixedly connected to each other, a middle fin group 8, and evenly distributed The middle heat sink 9 and the top fin group 10, wherein the bottom fin group 7 is located at the bottom of the enhanced cooling component, and the bottom fin group 7 close to the adjacent first electric push rod 6 is fixedly connected with an elastic force sensor 61 electrically connected to the control terminal, and an elastic member 62 is fixedly connected between the elastic force sensor 61 and the telescopic end of the adjacent first electric push rod 6, and the elastic member 62 is a spring. The two symmetrical middle fin groups 8 are respectively located on the left and right sides of the adjacent battery cells 5, and the middle fin groups 8 are all in a horizontal arrangement to facilitate the flow of air inside them. The evenly distributed middle heat sink 9 and the adjacent and evenly distributed battery cells 5 are staggered and tightly fitted, so that the evenly distributed middle heat sink 9 can detect whether the outer shell of the adjacent battery cell 5 is melted, and whether the adjacent battery cell 5 is slightly bulging, etc., wherein the battery cells 5 of the same group are provided with temperature sensors electrically connected to the control terminal, and the outer shell 1 is provided with an air inlet mechanism for ventilating the two battery compartments 2.

[0022] Please refer to Figure 2 and Figure 6-Figure 8The air inlet mechanism includes two air inlet members 11 symmetrically distributed on the left and right. The air inlet member 11 is provided with evenly distributed air diffuser holes (indicated in the air diffuser hole diagram) on one side close to the adjacent battery compartment 2. The air inlet member 11 is communicated with an external fan for supplying air to the adjacent battery compartment 2. The two air inlet members 11 are fixedly connected to the housing 1. Two air exhaust members 12 symmetrically distributed on the left and right are fixedly connected to the rear side of the housing 1. The air exhaust member 12 is provided with evenly distributed air inlet holes (indicated in the air inlet hole diagram) on one side close to the adjacent battery compartment 2. The air exhaust member 12 is communicated with the outside world for the convenience of exhausting the wind in the adjacent battery compartment 2 to the outside. Two air inlets 13 symmetrically distributed on the left and right are provided in the battery compartment 2, and uniformly distributed jet heads 14 are provided in the battery compartment 2. Wind enters the adjacent jet heads 14 through the air inlets 13, and then blows into different positions in the adjacent battery compartment 2. The jet heads 14 are connected to the adjacent air inlets 13, and a solenoid valve is provided in the jet heads 14. The middle heat dissipation plate 9 is provided with air guides 15 uniformly distributed up and down. The air guides 15 in the two adjacent middle heat dissipation plates 9 are staggered in the vertical direction, and the positions where the air is collected by different air guides 15 are changed to avoid collecting a large amount of flowing air on the same plane. , affecting the cooling efficiency of the air there. The cross-sectional area of ​​the side of the air duct 15 close to the adjacent middle fin group 8 is larger than the cross-sectional area of ​​the side away from the adjacent middle fin group 8. Therefore, the air is continuously pressurized when flowing in the air duct 15, and the flow velocity is gradually increased, which increases the flow velocity of the air when it flows out of the adjacent air duct 15. The outlet of the air duct 15 away from the adjacent middle fin group 8 is tilted upward, which is convenient for the symmetrical air duct 15 to be discharged upward after the gas flows out, reducing the situation where the air flow velocity is slowed down due to the impact. The air duct 15 is fixed with symmetrically distributed The wind blocking plate 16 is used to guide the nearby air to facilitate the air to flow into the adjacent air guide duct 15. The wind blocking plate 16 is fixedly connected to the adjacent middle fin group 8. The middle fin group 8 is provided with a plurality of evenly distributed groups of wind induction plates 17, each group includes evenly distributed wind induction plates 17, and the wind induction plates 17 are fixedly connected to one side of the adjacent middle fin group 8 close to the adjacent wind blocking plate 16. The wind induction plates 17 are used to guide the air that is not intercepted by the adjacent wind blocking plate 16, reduce the size of the vortex generated by the air flow behind the adjacent wind blocking plate 16, and thereby reduce the kinetic energy loss during air flow.

[0023] After the staff installs the device on the signal base station, they start the control terminal on the front side of the shell 1. After the control terminal is started, it monitors the voltage of the power grid electrically connected to the signal base station through the existing sensor, so that when the voltage of the power grid connected to the signal base station is unstable, the battery unit 5 in the device is electrically connected to the signal base station to provide a stable voltage to the signal base station to maintain the performance of the signal base station. The control terminal can control each group of battery units 5 individually, and intelligently formulate the charging and discharging methods of each group of battery units 5 to continuously provide a stable voltage to the signal base station.

[0024] When the control terminal starts the battery unit 5 in the device, the control terminal simultaneously controls the external fan to blow air into the two air inlets 11 and all the air inlet ducts 13 respectively, and the control terminal opens the solenoid valves in all the nozzles 14. The air entering the air inlet 11 directly enters the adjacent battery compartment 2 and flows to the adjacent exhaust piece 12 on the rear side. The air entering the air inlet duct 13 flows into the adjacent battery compartment 2 through the adjacent nozzle 14, and follows the airflow in the battery compartment 2 to flow to the adjacent exhaust piece 12 on the rear side. The heat generated by the battery unit 5 during operation is transferred to the adjacent enhanced cooling piece. When the air passes through the adjacent enhanced cooling piece during the flow, the adjacent enhanced cooling piece is dissipated, and then the working battery unit 5 is dissipated.

[0025] Taking the reinforced cooling part in the left part of the last group of reinforced cooling parts as an example, when the air flows backward in the battery compartment 2, the air enters the heat dissipation baffle 4, the bottom fin group 7, the middle fin group 8 and the top fin group 10, and dissipates the heat dissipation baffle 4, the bottom fin group 7, the middle fin group 8, the top fin group 10 and the middle heat dissipation plate 9. When the air passes through the adjacent wind blocking plate 16, the air is guided by the wind blocking plate 16 to flow into the adjacent air duct 15. The air dissipates the adjacent middle heat dissipation plate 9 in the air duct 15, and the middle heat dissipation plate 9 dissipates the adjacent battery unit 5. The air flows to the right along the adjacent air duct 15. When When the air flows to the outlet on the right side of the adjacent air duct 15, the flow velocity gradually increases because the air flow is squeezed by the adjacent air duct 15. Therefore, the air is ejected to the upper right direction at a faster flow speed than when entering the adjacent air duct 15, directly cooling the middle part of the adjacent battery cell 5. The air eventually flows back into the battery compartment 2 and continues to flow backward. The air guide plate 17 guides the air not intercepted by the wind baffle 16 to the rear side of the wind baffle 16, so as to reduce the vortex generated during the air flow behind the wind baffle 16, thereby ensuring that the wind baffle 16 located at the rear side collects enough air to dissipate the adjacent middle heat dissipation plate 9.

[0026] Because the air on both sides of the battery cells 5 in the same group is diverted to the middle, the heat dissipation efficiency of the middle part of the battery cells 5 in the same group is increased, and the probability of the middle part of the battery cells 5 being heated and melted is effectively reduced. The structural coordination between the cooling parts and the battery cells 5 in the adjacent groups is compact and reasonable, providing a better cooling effect and reducing space waste.

[0027] When the power grid connected to the signal base station no longer fluctuates and the electrical signal tends to be stable, the control terminal monitors the temperature of the battery cell 5 after use through multiple temperature sensors. When the temperature of the battery cell 5 after use gradually cools down, the control terminal controls the first electric push rod 6 on the lower side of the battery cell 5 after use to work. Take the last group of battery cells 5 and adjacent components in the left battery compartment 2 as an example: the control terminal controls the telescopic ends of the two first electric push rods 6 to extend toward each other, and the telescopic ends of the first electric push rods 6 push the adjacent elastic force sensor 61 and the adjacent enhanced cooling part to move to the side away from the adjacent battery cell 5 through the elastic part 62. If the battery cell 5 is slightly bulged due to excessive charging and discharging, the middle heat dissipation plate 9 of the enhanced cooling part is clamped by the adjacent battery cell 5. Therefore, the enhanced cooling part is difficult to be pushed by the adjacent elastic part 62, and the elastic force sensor 61 detects the elastic force of the adjacent elastic member 62 and transmits the signal to the control terminal. If the battery cell 5 generates a lot of heat during the charging and discharging process, causing the shell of the battery cell 5 to melt, the shell of the battery cell 5 will adhere to the middle heat dissipation plate 9 of the adjacent reinforced cooling member after cooling, resulting in the enhanced cooling member being difficult to be pushed by the adjacent elastic member 62. The elastic force sensor 61 detects the elastic force of the adjacent elastic member 62 and transmits the signal to the control terminal. The control terminal determines the state of the battery cell 5 at this location by receiving the signal of the elastic force sensor 61, and then accurately controls the use of this group of battery cells 5. Subsequently, the control terminal controls the first electric push rod 6 to drive the adjacent components to reset, and disconnects the battery cell 5 with a slight bulge or the battery cell 5 with a melted shell. The group of battery cells 5 will no longer be used subsequently, reducing the probability of accidents.

[0028] Embodiment 2: Because existing battery cells are all placed in the same space, when a group of battery cells experiences thermal runaway due to bulging, the group of battery cells is very likely to explode. If the battery cells are not isolated in time, the explosion is very likely to cause chain explosions in other groups of battery cells, further reducing the safety factor of existing battery cells.

[0029] Based on Example 1, please refer to Figure 8-Figure 10, and also includes an isolation mechanism that is symmetrically distributed on the left and right and is used to isolate different groups of battery cells 5. The isolation mechanism is arranged in an adjacent battery compartment 2. The isolation mechanism includes a plurality of groups of fixing columns 18 that are evenly distributed front and back, and each group includes two fixing columns 18 that are symmetrically distributed on the left and right. The number of groups of fixing columns 18 is one less than the number of groups of battery cells 5. An upper fixing plate 19 and a lower fixing plate are fixedly connected between the two symmetrically distributed fixing columns 18. The upper fixing plate 19 is fixedly connected to the adjacent end cover 3. The upper fixing plate 19 is used to seal the gap between the group of fixing columns 18 and the adjacent end cover 3. The lower fixing plate is fixedly connected to the adjacent battery compartment 2. The lower fixing plate The plate is used to seal the gap between the group of fixed columns 18 and the adjacent battery compartment 2. A swing plate 20 evenly distributed above and below is rotatably connected between the two symmetrically distributed fixed columns 18. When the swing plates 20 of the same group are rotated to a vertical state, the swing plates 20, fixed columns 18, upper fixed plates 19 and lower fixed plates of the same group cooperate to separate the two adjacent groups of battery cells 5. A second electric push rod 21 electrically connected to the control terminal is fixedly connected to the fixed column 18 on the left side of each group. A moving rod 22 is fixedly connected to the telescopic end of the second electric push rod 21. The moving rod 22 cooperates with the adjacent swing plate 20 through a gear rack transmission.

[0030] Please refer to Figure 9-11 A plurality of groups of ventilation ducts 23 evenly distributed on the left and right are commonly provided between the upper fixed plate 19 and the swing plates 20 of the same group and evenly distributed. The ventilation ducts 23 are used to guide the air nearby to flow when the adjacent swing plates 20 are in a vertical state. Each group includes two ventilation ducts 23 symmetrically distributed front and back. The front and rear sides of the swing plates 20 are provided with connecting holes evenly distributed up and down, and the connecting holes are connected with the adjacent ventilation ducts 23. The end cover 3 is provided with first ducts 24 evenly distributed on the left and right. The number of the first ducts 24 is the same as the number of the ventilation ducts 23 in each group of the upper fixed plates 19. The first ducts 24 are connected with the outside, and the first ducts 24 are connected with the adjacent ventilation ducts 23, so that the air in the adjacent ventilation ducts 23 can be discharged outward.

[0031] When the control terminal is using the battery unit 5, it first controls the telescopic ends of all the second electric push rods 21 to extend a certain distance, and the telescopic ends of the second electric push rods 21 drive the moving rod 22 to move upward a certain distance. The moving rod 22 rotates and opens the adjacent swing plate 20 through the adjacent rack gear. The swing plate 20 rotates to a tilted state. At this time, the gas in the battery compartment 2 can flow directly from the adjacent air inlet piece 11 on the front side to the adjacent air exhaust piece 12 on the rear side.

[0032] When the control terminal is using this group of battery cells 5, if the temperature sensor at the group of battery cells 5 detects a rapid increase in nearby temperature, the control terminal promptly disconnects from the group of battery cells 5, and promptly calls other groups of battery cells 5 in a dormant state to continuously supply power to the signal base station. After the control terminal disconnects from the group of battery cells 5, it starts the second electric push rod 21 at the group of battery cells 5 to seal the group of battery cells 5 to prevent the group of battery cells 5 from suddenly exploding.

[0033] Taking the battery unit 5 and adjacent components in the middle of the left battery compartment 2 as an example, the control terminal controls the two second electric push rods 21 on the front and rear sides of the battery unit 5 to reset respectively, and the telescopic end of the second electric push rod 21 drives the adjacent swing plate 20 to rotate and reset through the adjacent moving rod 22. At this time, the battery unit 5 at this location is blocked by the two adjacent groups of swing plates 20, and air is only introduced into this location through the adjacent nozzles 14. The air in the front battery compartment 2 flows upward through the ventilation duct 23 on the front side of the front swing plate 20, and the air in the rear battery compartment 2 flows upward through the ventilation duct 23 on the rear side of the rear swing plate 20. The air enters the adjacent first duct 24 and continues to flow backward, thereby ensuring smooth air flow. The air between the two groups of swing plates 20 continues to flow into the adjacent first duct 24 through the ventilation duct 23 on the front side of the rear swing plate 20 and the ventilation duct 23 on the rear side of the front swing plate 20. When the control terminal detects that the temperature in the battery cell 5 at that location returns to normal, the enhanced cooling component is used to detect the battery cell 5 at that location according to the above-mentioned working principle to assist in determining the status of the battery cell 5 at that location so as to decide whether to continue to use the group of battery cells 5 in the future. If the group of battery cells 5 is no longer used in the future, the control terminal synchronously controls the electromagnetic valves in several jet heads 14 adjacent to the group of battery cells 5 to be closed, so as to completely seal the group of battery cells 5 and reduce the probability of accidents occurring in the group of battery cells 5.

[0034] Example 3: Based on Example 2, please refer to Fig.11 and Fig.12, and also includes a forced water cooling mechanism that is symmetrically distributed on the left and right and is respectively arranged in adjacent end covers 3. The forced water cooling mechanism is used to force cooling of the battery cells 5 in the adjacent battery compartments 2. The forced water cooling mechanism includes second pipes 25 evenly distributed on the left and right. The front side of the second pipes 25 is communicated with an external fan. The second pipes 25 are all fixedly connected to the adjacent end covers 3. The number of the second pipes 25 is the same as that of the first pipes 24, and the second pipes 25 are located on the upper side of the adjacent first pipes 24. The end cover 3 is located on the upper side of the evenly distributed second pipes 25. A cooling cavity is provided. The cooling cavity is filled with coolant. The cooling cavity cools the coolant in the cooling cavity through the adjacent second pipes 25, thereby ensuring that the coolant is in a low temperature state when it flows downward, so as to maintain the coolant on the adjacent battery The heat dissipation efficiency of the battery unit 5 is improved. The upper fixed plate 19 is fixed with two third electric push rods 26 which are symmetrically distributed front and back and electrically connected to the control terminal near the connection between the adjacent ventilation duct 23 and the adjacent first duct 24. The telescopic end of the third electric push rod 26 is fixed with a fixed shell 27. The fixed shell 27 is provided with a vent. The ventilation duct 23 is connected with the adjacent fixed shell 27. The fixed shell 27 is connected with the adjacent first duct 24 and the adjacent second duct 25 through the vent. A plurality of evenly distributed groups of through holes are provided in the end cover 3. The through holes are used to guide the coolant therein to flow to the adjacent battery unit 5. The number of groups of through holes is the same as the number of groups of battery units 5. Each group contains evenly distributed through holes. A blocking component for blocking adjacent through holes is provided in the end cover 3.

[0035] Please refer to Fig.12 The blocking component includes two fourth electric push rods 28 symmetrically distributed on the left and right, and the two symmetrically distributed fourth electric push rods 28 are fixedly connected to the cooling cavity of the end cover 3. The telescopic ends of the two symmetrically distributed fourth electric push rods 28 are commonly fixedly connected with a square ring 29, and the lower side of the square ring 29 is fixedly connected with a uniformly distributed conical blocking block 30. The conical blocking block 30 is used to block adjacent through holes and control the timing of the adjacent coolant flowing downward. The connection between the air inlet member 11 and the fan and the connection between the air exhaust member 12 and the outside are both provided with a water-proof automatic valve. The water-proof automatic valve is an existing device (not shown in the figure) used to prevent the coolant from leaking outward. The upper part of the top fin group 10 is provided with an inclined surface for guiding water to increase the contact area between water and the adjacent cooling reinforcement member. The middle fin group 8 is provided with uniformly distributed liquid guide holes 31. The liquid guide holes 31 in the middle fin group 8 are staggered, and the uniformly distributed liquid guide holes 31 are staggered with all the wind blocking plates 16 on the adjacent middle fin group 8.

[0036] When the control terminal controls the external fan to introduce air into the adjacent battery compartment 2, it also controls the fan to introduce air into all the second pipes 25. The flowing air in the second pipes 25 cools the coolant in the cooling cavity in the adjacent end cover 3 to facilitate subsequent use.

[0037] When the temperature of a battery cell 5 rises unexpectedly during use, the control terminal controls the adjacent swing plate 20 to seal the battery cell 5 at that location and continuously detects the temperature of the battery cell 5. If it is difficult to cool the battery cell 5 by air, or the temperature of the battery cell 5 continues to rise, the control terminal simultaneously activates the fourth electric push rod 28 on the upper side of the battery cell 5. The telescopic end of the fourth electric push rod 28 drives the square ring 29, the conical blocking block 30 and other components to continuously retract upwards. The conical blocking block 30 moves upwards to release the seal of the adjacent through hole, and the coolant in the adjacent cooling cavity flows downward through the opened through hole. The coolant flows into the battery cell 5 where the temperature is abnormally increased. During the downward flow, the coolant is guided by the upper inclined surface of the adjacent top fin group 10, and first contacts the top fin group 10. Then, after the coolant contacts the battery cell 5, it flows to the gap of the adjacent middle heat sink 9 of the battery cell 5 and around the battery cell 5. When the coolant flows to the middle fin group 8 adjacent to the battery cell 5, the coolant gradually flows downward through the adjacent liquid guide holes 31 to cool the adjacent middle fin group 8, thereby enhancing the cooling efficiency of the cooling element for the battery cell 5 by exchanging heat with the coolant.

[0038] When the coolant has completely flowed out of the adjacent cooling chamber, the coolant just covers the battery unit 5, and the control terminal controls the third electric push rod 26 in the upper fixing plate 19 adjacent to the battery unit 5 to work. Fig.11 The internal parts are taken as an example of the parts on the front side of the battery unit 5 (hereinafter referred to as Fig.11 The control terminal controls the telescopic end of the third electric push rod 26 on the right side to drive the adjacent fixed shell 27 to move upward, and the vent hole on the right fixed shell 27 is disconnected from the adjacent first pipe 24 and inserted into the adjacent second pipe 25. The vent hole on the right fixed shell 27 is connected with the adjacent second pipe 25, and the fixed shell 27 on the left side and the adjacent parts remain stationary. At this time, the air flowing on the left side flows upward through the ventilation pipe 23 on the left side of the upper fixed plate 19 and the swing plate 20, and the air flows to the corresponding fixed shell 27 through the fixed shell 27 on the left side. The air in the second pipe 25 passes through the fixed shell 27 on the right side and enters the ventilation pipe 23 on the right side of the upper fixed plate 19 and the swing plate 20. The air flows into the battery cell 5 through the ventilation pipe 23. The air in the second pipe 25 is blown into the coolant through the connected ventilation pipe 23, which speeds up the circulation of the coolant and increases the cooling speed of the battery cell 5. After that, the air enters the coolant and gradually flows upward and finally gathers in the cooling chamber.

[0039] When the coolant is discharged, the control terminal remotely alarms the staff, reminding them to check the device in time.

[0040] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
