TECHNICAL FIELD

[0001] The application belongs to the technical field of lithium battery power supply in oil and gas fields, and particularly relates to a control device and a control method of energy storage lithium batteries applied to peak load shifting of power grids. BACKGROUND

[0002] Lithium batteries are a kind of batteries with lithium metal or lithium alloy as positive and negative electrode materials and using non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. The fifth generation product of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance-price ratio are superior to those of lithium ion batteries.

[0003] Through retrieval, a smart low-voltage lithium battery energy storage control system (CN201810640067.X) is disclosed.

[0010] Furthermore, a support plate is provided at the upper end of the base plate near the right side, and five groups of vertical slots are opened on the support plate near the right side. A hydraulic telescopic rod is provided at the bottom end of the vertical slot, and a slider is movably provided inside the vertical slot. The slider is movably provided inside the vertical slot through the hydraulic telescopic rod.

[0011] Furthermore, a transverse groove is provided through the side wall of the slider near both sides, an adjustment plate is provided inside the transverse groove, and a placement plate is provided at the other end of the adjustment plate. The placement plate is movably arranged on the side of the support plate near the bearing plate through the slider and the adjustment plate.

[0012] Furthermore, a limit plate is provided on the upper end of the placement plate near one side, brackets are provided on both sides of the placement plate, a baffle is provided between the two groups of brackets, a telescopic pull rod is provided on both sides of the placement plate and between both sides of the baffle, a spring is wound around the surface of the telescopic pull rod, a rotating shaft is provided between the bracket and the placement plate, the baffle is movably arranged on one side of the placement plate through the telescopic pull rod and the spring in conjunction with the bracket, a lithium battery body is placed on the placement plate, a clamping plate is provided on the lithium battery body near the position of the limit plate, and the limit plate fits with the clamping plate.

[0013] The energy storage lithium battery control method used for peak shaving and valley filling in the power grid has the following specific steps:

[0014] Step 1: Use vertical plate 1 and vertical plate 2 to set several groups of supporting plates parallel to each other on the upper end of the bottom plate, start the electric telescopic rod to move the push plate to a position close to the side plate, and then place the lithium battery body between the two groups of partitions. By starting the fan and the water pump, the water pump moves the water inside the water tank to the inside of the S-shaped tube and then flows into the water tank from the other end, forming a water circulation system;

[0015] Step 2: When the lithium battery body needs to be taken out, start the corresponding hydraulic telescopic rod to move the slider along the vertical slot, move the baffle to a position where its top is parallel to the upper surface of the carrying plate, push the adjusting plate to move the baffle under the carrying plate, and then move the placement plate upward. At this time, the baffle rotates counterclockwise along the rotating shaft under the obstruction of the carrying plate, and moves the placement plate to the same horizontal position as the upper surface of the carrying plate. Push the adjusting plate set on one side of the slider, and the adjusting plate moves the placement plate to the left or right through the horizontal slot until it fits with the carrying plate. Start the electric telescopic rod to slowly push the lithium battery body outward, and the lithium battery body moves to the right to contact the roller, and then the lithium battery body continues to move to the right until the card moves to the limit plate;

[0016] Step 3: Slowly move the placement plate downwards, and the push plate continues to move to the right along the slide. The angle between the lithium battery body and the load plate gradually increases, and then the lithium battery body will fall onto the placement plate.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. By starting the fan, the fan blows air through the cavity through the vent to between the two groups of partitions, thereby making the air flow. By starting the water pump, the water pump moves the water inside the water tank to the inside of the S-shaped tube and then flows into the water tank from the other end, thereby forming a water circulation system, wherein the S-shaped tube is distributed inside the cavity. The water reduces the temperature of the side wall of the S-shaped tube during the flow process. The air's own temperature will be absorbed by the surface of the S-shaped tube when passing through it. Then, the air with lower temperature moves through the vent to between the two groups of partitions, wherein a dust baffle is provided, which can prevent dust from falling onto the surface of the lithium battery body while slowing down the speed at which the air with lower temperature escapes from between the partitions. Since the air temperature is low, it will absorb the temperature of the surface when it contacts the surface of the lithium battery body, thereby reducing the temperature of the lithium battery body itself, and preventing the surface temperature of the lithium battery body from being too high and affecting its use.

[0019] 2. Start the electric telescopic rod and slowly push the lithium battery body outward. The lithium battery body moves to the right and contacts the roller. Then the lithium battery body continues to move to the right until the card plate moves to the limit plate. At this time, slowly move the placement plate downward. At this time, since the lithium battery body is limited by the card plate and the limit plate, the end of the lithium battery body located between the two sets of partitions is tilted upward. At this time, the push plate continues to move to the right along the slide groove. The angle between the lithium battery body and the load-bearing plate gradually increases, and then the lithium battery body will fall onto the placement plate. In the process of the placement plate moving downward, the tension of the spring causes the telescopic rod to contract. At this time, the baffle rotates clockwise through the bracket and the rotating shaft to a position horizontal to the lithium battery body, thereby preventing the lithium battery body from falling and being damaged during the movement of the placement plate, thereby facilitating the staff to remove the battery.

A side panel 9 is provided, a roller 8 is provided on the side of the upper end surface of the supporting plate 4 away from the side panel 9, a number of groups of vents 10 are equidistantly provided on the right side of the side panel 9, a dust baffle 11 is provided on the right side of the side panel 9 near the top, vertical plates 14 are provided near both sides between the supporting plate 4 and the dust baffle 11, a fan 12 is provided near the bottom on the side of the side panel 9 away from the dust baffle 11, and the fan 12 is connected with the vent 10 through the cavity. By starting the fan 12, the fan 12 blows air through the cavity through the vent 10 into between the two groups of partitions 13, thereby allowing the air to flow.

[0031] A plurality of partitions 13 are provided on the side of the side panel 9 away from the fan 12. The vent 10 is located between the two partitions 13.

One end of the S-shaped tube 28 is connected to the water pump, and the other end is provided at the bottom of the water tank 2. The water tank 2 is filled with water. By starting the water pump, the water pump moves the water inside the water tank 2 to the inside of the S-shaped tube 28 and then flows into the water tank 2 from the other end, thereby forming a water circulation system. The S-shaped tube 28 is distributed inside the cavity, and water flows in the water tank 2.

Since the air temperature is low, it will absorb the temperature of the surface of the lithium battery body 26 when it contacts the surface of the lithium battery body 26, thereby reducing the temperature of the lithium battery body 26 itself.

[0032] Example 2

[0033] The second embodiment includes all the technical features described in the first embodiment. Figures 1 to 6As shown, a control device and a control method for energy storage lithium batteries used in peak shaving and valley filling of power grids are shown, comprising a bottom plate 1, a water tank 2 is provided at the upper end of the bottom plate 1 near one side, a vertical plate 3 is provided at the upper end of the bottom plate 1 near both sides, a plurality of groups of bearing plates 4 are provided above the vertical plate 3, the plurality of groups of bearing plates 4 are arranged parallel to each other, a plurality of groups of chutes 5 are provided at the upper end of the bearing plates 4, an electric telescopic rod 6 is provided on the inner side wall of the chutes 5, a push plate 7 is provided on the side of the electric telescopic rod 6 away from the side wall of the chutes 5, the push plate 7 slides left and right along the chutes 5 through the electric telescopic rod 6, and the upper end of the bottom plate 1 near the left side is provided. A side panel 9 is provided, a roller 8 is provided on the side of the upper end surface of the supporting plate 4 away from the side panel 9, a number of groups of vents 10 are equidistantly provided on the right side of the side panel 9, a dust baffle 11 is provided on the right side of the side panel 9 near the top, vertical plates 14 are provided near both sides between the supporting plate 4 and the dust baffle 11, a fan 12 is provided near the bottom on the side of the side panel 9 away from the dust baffle 11, and the fan 12 is connected with the vent 10 through the cavity. By starting the fan 12, the fan 12 blows air through the cavity through the vent 10 into between the two groups of partitions 13, thereby allowing the air to flow.

[0034] A plurality of partitions 13 are provided on the side of the side panel 9 away from the fan 12. The vent 10 is located between the two partitions 13. The interior of the side panel 9 is a cavity. An S-shaped tube 28 is provided inside the side panel 9. A water pump is provided inside the water tank 2. One end of the S-shaped tube 28 is connected to the water pump, and the other end is provided at the bottom of the water tank 2. The water tank 2 is filled with water. By starting the water pump, the water pump moves the water inside the water tank 2 to the inside of the S-shaped tube 28 and then flows into the water tank 2 from the other end, thereby forming a water circulation system. The S-shaped tube 28 is distributed inside the cavity, and water flows in the water tank 2. During the process, the temperature of the side wall of the S-shaped tube 28 is reduced, and the temperature of the air itself will be absorbed by the surface of the S-shaped tube 28 when passing through it. Then, the air with lower temperature moves between the two groups of partitions 13 through the vent 10, wherein a dust baffle 11 is provided, which can prevent dust from falling on the surface of the lithium battery body 26 while slowing down the speed of the air with lower temperature escaping from between the partitions 13. Since the air temperature is low, it will absorb the temperature of the surface of the lithium battery body 26 when it contacts the surface of the lithium battery body 26, thereby reducing the temperature of the lithium battery body 26 itself.

[0035] In addition, Example 2 further records:

[0036] A support plate 15 is provided at the upper end of the base plate 1 near the right side, and five groups of vertical slots 16 are opened near the right side of the support plate 15. A hydraulic telescopic rod 17 is provided at the bottom end of the vertical slot 16. A slider 18 is movably provided inside the vertical slot 16. The slider 18 is movably set inside the vertical slot 16 through the hydraulic telescopic rod 17. A transverse slot 19 is opened through the side wall of the slider 18 near both sides, and an adjustment plate 20 is provided inside the transverse slot 19. A placement plate 21 is provided at the other end of the adjustment plate 20. The placement plate 21 is movably set on the side of the support plate 15 near the load-bearing plate 4 through the slider 18 and the adjustment plate 20.

[0037] A limit plate 22 is provided near one side of the upper end of the placement plate 21, and brackets 23 are provided on both sides of the placement plate 21. A baffle 24 is provided between the two groups of brackets 23, and a telescopic pull rod 25 is provided between both sides of the placement plate 21 and both sides of the baffle 24. A spring is wound around the surface of the telescopic pull rod 25, and a rotating shaft is provided between the bracket 23 and the placement plate 21. The baffle 24 is movably provided on one side of the placement plate 21 through the telescopic pull rod 25 and the spring in conjunction with the bracket 23. A lithium battery main body 26 is placed on the placement plate 21, and a card plate 27 is provided near the position of the lithium battery main body 26 near the limit plate 22. The limit plate 22 fits with the card plate 27, and the electric telescopic rod 6 is started to slowly push the lithium battery main body 26 outward. The lithium battery main body 26 moves to the right and contacts the roller 8, and then the lithium battery main body 26 continues Move rightward until the clamping plate 27 moves onto the limiting plate 22. Then, slowly move the placement plate 21 downward. As the lithium battery body 26 is restrained by the clamping plate 27 and the limiting plate 22, the end of the lithium battery body 26 located between the two sets of partitions 13 tilts upward. The push plate 7 then continues to move rightward along the chute 5. The angle between the lithium battery body 26 and the support plate 4 gradually increases, and the lithium battery body 26 falls onto the placement plate 21. As the placement plate 21 moves downward, the spring tension causes the telescopic rod 25 to retract. The baffle 24 rotates clockwise, in conjunction with the rotating shaft, via the bracket 23, to a position level with the lithium battery body 26. This prevents the lithium battery body 26 from falling and being damaged during the movement of the placement plate 21, making it easier for staff to remove the lithium battery.

[0038] Example 4

[0039] First, the staff arranges several groups of supporting plates 4 parallel to each other on the upper end of the bottom plate 1 through the vertical plate 1 3 and the vertical plate 2 14, starts the electric telescopic rod 6 to move the push plate 7 to a position close to the side plate 9, and then places the lithium battery body 26 between the two groups of partitions 13 respectively. By starting the fan 12, the fan 12 blows air through the cavity through the vent 10 to between the two groups of partitions 13, thereby making the air flow. By starting the water pump, the water pump moves the water inside the water tank 2 to the inside of the S-shaped tube 28 and then flows into the water tank 2 from the other end, thereby forming a water circulation system, wherein the S-shaped tube 28 is distributed inside the cavity. The water reduces the temperature of the side wall of the S-shaped tube 28 during the flow process, and the air naturally flows through the surface of the S-shaped tube 28. The body temperature will be absorbed by it, and then the lower temperature air will move between the two groups of partitions 13 through the vent 10, wherein the dust baffle 11 is provided, which can prevent dust from falling on the surface of the lithium battery body 26 and at the same time slow down the speed of the lower temperature air escaping from between the partitions 13. Since the air temperature is low, it will absorb the surface temperature of the lithium battery body 26 when it comes into contact with the surface of the lithium battery body 26, thereby lowering the temperature of the lithium battery body 26 itself, and preventing the surface temperature of the lithium battery body 26 from being too high and affecting its use. When the lithium battery body 26 needs to be taken out, the corresponding hydraulic telescopic rod 17 is started to move the slider 18 along the vertical slot 16, and the baffle 24 is moved to a position where its top end is parallel to the upper end surface of the carrying plate 4, and the baffle 24 is pushed The movable adjustment plate 20 moves the baffle 24 to the bottom of the carrying plate 4, and then the placing plate 21 moves upward. At this time, the baffle 24 rotates counterclockwise along the rotating shaft under the obstruction of the carrying plate 4, and moves the placing plate 21 to the same horizontal position as the upper end surface of the carrying plate 4, pushing the adjustment plate 20 set on one side of the slider 18. The adjustment plate 20 moves the placing plate 21 to the left or right through the transverse groove 19 until it fits with the carrying plate 4, and starts the electric telescopic rod 6 to slowly push the lithium battery body 26 outward. The lithium battery body 26 moves to the right and contacts the roller 8, and then the lithium battery body 26 continues to move to the right until the card plate 27 moves onto the limit plate 22. At this time, the placing plate 21 is slowly moved downward. At this time, since the lithium battery body 26 passes through the card plate 2 7 and the limiting plate 22 cause one end of the lithium battery body 26 located between the two groups of partitions 13 to tilt upward. At this time, the push plate 7 continues to move to the right along the slide groove 5, and the angle between the lithium battery body 26 and the supporting plate 4 gradually increases. Then the lithium battery body 26 will fall onto the placement plate 21. During the downward movement of the placement plate 21, the tension of the spring causes the telescopic pull rod 25 to contract. At this time, the baffle 24 rotates clockwise through the bracket 23 in conjunction with the rotating shaft and rotates to a position horizontal to the lithium battery body 26, preventing the lithium battery body 26 from falling and being damaged during the movement of the placement plate 21, thereby facilitating the staff to remove the lithium battery, and then facilitating the staff to control the removal of the lithium battery body 26 and the cooling of its surface.

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] 1、By starting the fan, the fan blows air through the vent into the space between the two sets of partitions, thereby making the air flow, by starting the water pump, the water pump moves the water inside the water tank into the S-shaped pipe and then flows into the water tank from the other end, thereby forming a water circulation system, wherein the S-shaped pipe is distributed inside the cavity, and the water flowing in the process reduces the temperature of the side wall of the S-shaped pipe, and the temperature of the air passing through the surface of the S-shaped pipe is absorbed by the S-shaped pipe, and then the air with lower temperature moves to the space between the two sets of partitions through the vent, wherein the dustproof plate is provided, which can slow down the speed of the air with lower temperature escaping from the space between the two sets of partitions while avoiding dust falling on the surface of the lithium battery body, and since the air temperature is low, it will absorb the surface temperature of the lithium battery body when it contacts the surface of the lithium battery body, thereby reducing the temperature of the lithium battery body itself and avoiding the influence of the high temperature of the surface of the lithium battery body on use.

[0042] 2、By starting the electric telescopic rod, the lithium battery body is slowly pushed outward, the lithium battery body moves to the right and contacts the roller, then the lithium battery body continues to move to the right until the clamping plate moves to the limiting plate, at this time the placing plate is slowly moved downward, at this time the lithium battery body is located between the two sets of partitions and is lifted up due to the limiting of the clamping plate and the limiting plate, at this time the push plate continues to move right along the sliding groove, the angle between the lithium battery body and the bearing plate gradually increases, then the lithium battery body will fall on the placing plate, in the process of moving the placing plate downward, the spring tension makes the telescopic pull rod contract, at this time the baffle rotates clockwise through the support cooperation with the rotating shaft, and rotates to the horizontal position with the lithium battery body, thereby avoiding the lithium battery body from falling and damaging in the process of moving the placing plate, thereby facilitating the staff to take out the battery.
