Description

Technical Field

[0001] The present invention belongs to the field of safety technology of supercharging energy storage systems, relates to heat dissipation technology of energy storage power stations, and specifically relates to a supercharging energy storage adaptive cooling system. Background Art

[0002] With the popularization of new energy vehicles, the number of new energy vehicles has increased significantly. In order to ensure the normal use of new energy vehicles, new energy vehicles need to be charged in time. The current charging methods of new energy vehicles mainly include slow charging, fast charging and super charging. It usually takes 7-8 hours to fully charge a new energy vehicle with slow charging. Users usually charge it through their own charging piles after getting home from get off work. However, in most cases, it is necessary to quickly charge a new energy vehicle. It usually takes 1-2 hours to fully charge a new energy vehicle with fast charging, and it usually takes 10-20 minutes to fully charge it with super charging. Most users use their cars during the day and need to charge during the day, which leads to super charging during the daytime period. The power grid load continues to run at high load, resulting in a shortage of power grid resources. The energy storage power station is fully charged at night when electricity consumption is low. During the peak period of electricity consumption during the day, the intelligent control terminal of the super charging energy storage power station is used to reasonably allocate resources, and the energy storage power station is used to charge new energy vehicles, which can effectively reduce the power grid load during the day.

[0003] However, the supercharging energy storage system (energy storage power station) has a heat dissipation problem. Heat dissipation occurs when the battery is charged and discharged. When the heat is not discharged in time and exceeds the normal temperature range, the energy storage power station will have great safety hazards. As the battery temperature increases, the probability of battery bulging and breaking is greater. In this case, the normal working rate of the battery decreases. What's more, thermal runaway of the energy storage battery will lead to an explosion in the energy storage power station. In the past 10 years, a total of 30 energy storage power station fires and explosions have occurred worldwide. It is very urgent to control the temperature of the energy storage power station.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] See also Figure 1-Figure 6 As shown, the specific embodiments provided by the present invention are as follows:

[0058] Embodiment 1:

[0059] The supercharged energy storage adaptive cooling system is characterized by comprising:

[0060] Trigger component 1;

[0061] A cooling assembly having a cooling pipe and a water pump;

[0062] Wherein, the trigger component 1 is used to sense the temperature change of the object to be tested and issue a trigger action;

[0063] The cooling pipe comprises a liquid inlet pipe 211, a liquid outlet pipe 212 and a plurality of liquid distributors 213, and the two ends of the liquid distributors 213 are respectively sealed and connected to the liquid inlet pipe 211 and the liquid outlet pipe 212;

[0064] Wherein, the water pump is located inside the liquid inlet pipe 211 and is used to increase the pressure inside the liquid inlet pipe 211;

[0065] The cooling pipe has a controlled valve, which is located on the liquid dispensing pipe 213 . The controlled valve changes the flow of the liquid dispensing pipe 213 in response to a triggering action.

[0066] The energy storage power station includes multiple battery packs and battery cabinets. The battery packs are placed in the battery cabinet. When the surface temperature of the battery pack rises, the battery is prone to bulging. If the battery is in a bulging or broken state for a long time, the battery life will be greatly reduced. In serious cases, it may cause an explosion accident in the energy storage power station, which not only wastes resources, but also causes a lot of insecurity to users. For this reason, it is very valuable to provide a cooling system for an intelligent energy storage power station. The existing cooling method of the energy storage power station is based on an electrical sensor. The temperature of the surface of the battery pack is detected by a temperature detection sensor. According to the data obtained by the sensor feedback, the cooling demand is analyzed and the cooling is performed. In many cases, the battery packs do not all work at the same time, but the temperature sensor needs to monitor the temperature of each battery pack in real time to determine whether there is a cooling demand. For most battery packs with normal temperatures, they must be monitored at any time. This method wastes resources. Secondly, the signal transmission sensor and the cooling system have a very cumbersome line arrangement. The wiring occupies the space of the battery pack. In an environment with a large temperature difference, the line arrangement is easily affected by temperature. In addition, once a line fails, the workload of the staff to check is very large.

[0067] In this embodiment, if Figure 1 As shown, (a) is a side view of the energy storage power station cooling system, and (b) is a top view of the energy storage power station cooling system. Figure 2Shown is a schematic diagram of a controlled valve, providing a supercharged energy storage adaptive cooling system, characterized in that it includes a trigger component; a cooling component with a cooling pipe and a water pump; wherein the trigger component is used to sense the temperature change of the object to be tested and issue a trigger action; wherein the cooling pipe has an inlet pipe 211, an outlet pipe 212 and a plurality of liquid distribution pipes 213, and the two ends of the liquid distribution pipe are respectively sealed with the inlet pipe and the outlet pipe; wherein the water pump is located inside the inlet pipe, and is used to increase the pressure inside the inlet pipe; the cooling pipe has a controlled valve 3, and the controlled valve is located on the liquid distribution pipe, and the controlled valve responds to the trigger action to change the flow of the liquid distribution pipe. The present invention provides a supercharged energy storage adaptive cooling system, in which a trigger component is fixed on the inner wall of a battery box, and the trigger component extends through the battery box to the outer wall of the battery box. A controlled valve and a trigger component are installed for each battery pack, and each battery pack shares a liquid inlet pipe and a liquid outlet pipe. The coolant enters from the liquid inlet pipe, flows through each liquid dispensing pipe, and finally flows into the liquid outlet pipe through the liquid dispensing pipe. The battery pack is cooled by flowing through the liquid dispensing pipe. The present invention senses the temperature of the battery pack through the trigger component, and the triggering action of the trigger component can drive the controlled valve to further act to change the flow of the liquid dispensing pipe. The greater the flow of the coolant through the liquid dispensing pipe, the faster the cooling speed, and vice versa. If the battery pack temperature is within the allowable range and the controlled valve is closed, it means that the battery pack is normal and does not need to be cooled. When the battery dissipates heat due to operation, if the temperature rises to a certain level, the trigger component can change the triggering action of the controlled valve, and the flow rate of the coolant is controlled by changing the flow of the valve, thereby reducing the temperature of the battery pack. The present invention monitors the temperature of the battery pack by using a temperature sensing component. It can monitor the temperature of the battery pack in real time without using a temperature sensor, and cool it according to the temperature. The present invention can save electric energy and save the space utilization rate of the battery pack, and can achieve the purpose of low-cost adaptive cooling in the energy storage power station.

[0068] Embodiment 2:

[0069] The controlled valve has a pipe passage, a valve body 33 and a valve body housing 32;

[0070] The tube channel has a liquid inlet channel 311 and a liquid outlet channel 312, and the tube channel is sealed and connected to the liquid dispensing tube 213, so that the inner cavity of the valve body shell 32 is sealed with the inner cavity of the liquid dispensing tube 213;

[0071] The valve body shell 32 has a cavity, which is connected to the inner cavity of the pipe channel, and the cross-sectional area of ​​the cavity is larger than the cross-sectional area of ​​the pipe channel;

[0072] The valve body 33 is located in the cavity of the valve body shell 32, and the valve body 33 is used to change the flow of the cavity in response to the triggering action.

[0073] In this embodiment, if Figure 3As shown, the controlled valve has a pipe channel, a valve body 33 and a valve body shell 32, wherein the pipe channel has a liquid inlet channel 311 and a liquid outlet channel 312, and the pipe channel is used to be sealed and connected with the liquid distributor 213, so that the inner cavity of the valve body shell 32 is sealed with the inner cavity of the liquid distributor 213; wherein the valve body shell has a cavity, the cavity is connected with the inner cavity of the pipe channel, and the cross-sectional area of ​​the cavity is larger than the cross-sectional area of ​​the pipe channel; wherein the valve body is located in the cavity of the valve body shell, and the valve body is used to change the flow of the cavity in response to the triggering action. The coolant enters the controlled valve from the liquid inlet channel through the liquid distributor, and the coolant continues to flow into the liquid distributor from the liquid outlet channel through the valve body. The flow of the liquid distributor is controlled by the degree of opening and closing of the valve body, thereby controlling whether the battery pack is cooled or the cooling speed.

[0074] Embodiment 3:

[0075] The valve body has a fixed baffle 331, a movable baffle 332 and a torsion spring 333;

[0076] The plane where the fixed baffle 331 is located is a first plane, and the first plane is perpendicular to the Y direction, and the Y direction is the axial direction of the tube channel;

[0077] In the cross section with the plane perpendicular to the Y direction, the cross-sectional area of ​​the cavity on the first plane is the largest;

[0078] The fixed baffle 331 comprises a fixed plate and n evenly distributed first sector-shaped pieces 3311;

[0079] The included angle of the adjacent first sector pieces is equal to the sector angle of the first sector piece, the arc edge of the first sector piece is sealed and fixedly connected to the inner wall of the valve body shell, the fixed plate is located at the center of the fixed baffle, and the outer edge of the fixed plate is fixedly connected to one end of the first sector piece close to the center of the circle;

[0080] The movable baffle 332 has a rotating disk and n evenly distributed second sector-shaped pieces 3321, where n is an integer greater than 1;

[0081] The included angle of the adjacent second sector pieces is equal to the sector angle of the second sector piece, the arc edge of the second sector piece is sealed and connected to the inner wall of the valve body shell, the movable baffle piece and the valve body shell can be relatively displaced, the rotating disk is located at the center of the movable baffle piece, and the outer edge of the rotating disk is fixedly connected to one end of the second sector piece close to the center of the circle;

[0082] The movable baffle 332 is located on a side of the fixed baffle 331 facing the liquid inlet channel, and the movable baffle 332 is in contact with the fixed baffle 331;

[0083] The torsion spring 333 is fixed on the fixed plate, one force-bearing end of the torsion spring 333 is fixed on the first sector-shaped piece 3311, and the other force-bearing end of the torsion spring 333 is fixed on the second sector-shaped piece 3321;

[0084] The torsion spring 333 has a first state and a second state.

[0085] The first state is that the gap between the second sector piece and the fixed baffle piece overlaps, and the cavity is not connected in the first state;

[0086] The second state is that the second sector-shaped piece partially overlaps / completely overlaps with the first sector-shaped piece, and the cavity is connected in the second state;

[0087] When the torsion spring is not subjected to external force, the torsion spring has a tendency to turn from the second state to the first state.

[0088] In this embodiment, if Figure 4 As shown, the triggering action can change the position of the movable baffle, change the gap between the first fan-shaped piece 3311 and the second fan-shaped piece 3321, thereby controlling the flow of the controlled valve, and achieving the effect of cooling the battery pack. The torsion spring 333 is fixed on the fixed disk, one force-bearing end of the torsion spring is fixed on the first fan-shaped piece, and the other force-bearing end of the torsion spring is fixed on the second fan-shaped piece; the torsion spring has a first state and a second state, the first state is that the gap between the second fan-shaped piece and the fixed baffle overlaps, and the cavity is not connected in the first state; the second state is that the second fan-shaped piece partially overlaps / completely overlaps with the first fan-shaped piece, and the cavity is connected in the second state; when the torsion spring is not subjected to external force, the torsion spring has a tendency to turn from the second state to the first state. When the torsion spring is not subjected to external force, the gap between the second fan-shaped piece and the fixed baffle overlaps, so that the cavity is not connected, and the coolant in the liquid distribution tube does not flow. When the torsion spring is subjected to external force, the second sector-shaped piece partially overlaps with the first sector-shaped piece / completely overlaps, so that the cavity is connected, and the coolant in the liquid distribution tube flows rapidly, thereby driving the heat of the battery pack, thereby achieving the effect of automatic cooling of the battery pack. When the torsion spring is not subjected to external force, the movable baffle and the fixed baffle are relatively displaced until the cavity is disconnected.

[0089] Embodiment 4:

[0090] The trigger assembly comprises a temperature sensing component, a positioning component and a wedge-shaped component;

[0091] The wedge-shaped member can contact and squeeze the second sector piece, so that the second sector piece is displaced, and the wedge-shaped member has a bottom end, which is an end away from the valve body;

[0092] Taking the plane perpendicular to the Y direction as the cross section, the farther the distance from the valve body, the larger the cross-sectional area of ​​the wedge-shaped component;

[0093] Wherein, the positioning member is located on the side of the valve body facing the liquid outlet channel, and the outer edge of the positioning member is fixed to the inner wall of the valve body shell;

[0094] The positioning member is a rectangular pipe, and the wedge-shaped member can be displaced in the Y direction in the rectangular pipe;

[0095] Wherein, the temperature sensing component has a fixed end and a movable end, and the position and shape of the movable end can be changed;

[0096] The bottom end is used to respond to the triggering action generated by the active end of the temperature sensing component to change the flow rate of the cavity.

[0097] When the connecting rod is subjected to force from the movable end, since the connecting rod and the valve body shell are sealed with an elastic medium, the thrust direction of the connecting rod on the wedge-shaped member is easily changed by the elastic medium, and the force direction of the wedge-shaped member is uncertain, which may cause the wedge-shaped member to squeeze the fixed baffle and cause the valve body to be damaged, greatly reducing the service life of the controlled valve.

[0098] In this embodiment, if Figure 5 As shown, the trigger assembly 1 has a temperature sensing component 11, a positioning member 13 and a wedge-shaped member 12; in one embodiment, the temperature sensing component 11 is a sheet metal, and when the temperature rises, the length and width of the sheet metal increase. The temperature sensing component 11 sends a trigger action to the wedge-shaped member 12, and the wedge-shaped member 12 can be displaced in the Y direction in the rectangular pipe. When the temperature sensing component 11 senses that the temperature rises to a higher position, the wedge-shaped member 12 is displaced toward the liquid inlet channel, thereby causing the second fan-shaped piece to be displaced, thereby opening the controlled valve, and the coolant quickly flows through the liquid distribution pipe of the battery pack to cool it. When the temperature of the battery pack is reduced to the normal temperature, the trigger assembly returns to the default state, and the wedge-shaped member is displaced toward the liquid outlet channel until the trigger assembly no longer detects displacement and deformation. The present invention determines the force direction of the wedge-shaped member through the positioning member, which can increase the service life of the controlled valve.

[0099] Embodiment 5:

[0100] The trigger assembly has a connecting rod, which passes through the valve body shell and is connected to the bottom end, one end of the connecting rod is connected to the movable end, the other end of the connecting rod is connected to the bottom end, and the connecting rod is sealed with the valve body shell through an elastic medium.

[0101] In this embodiment, since the wedge-shaped component will respond to changes in the temperature sensing component, the trigger assembly has a connecting rod 1233, which passes through the valve body shell and is connected to the bottom end, one end of the connecting rod is connected to the movable end 112, and the other end of the connecting rod is connected to the bottom end 123. The connecting rod 1233 is sealed to the valve body shell by an elastic medium, so that the trigger assembly can maintain the sealing of the controlled valve body when the trigger action is triggered.

[0102] Embodiment 6:

[0103] The wedge-shaped member is a right-angled triangular sheet metal, and the wedge-shaped member has a first right-angled side, a second right-angled side and a hypotenuse;

[0104] Wherein, the first right-angled side is parallel to the first plane;

[0105] The second right-angled side and the first sector piece do not generate any force, and the hypotenuse and the second sector piece can contact and displace relative to each other; and the following conditions are satisfied:

[0106] When the beveled edge contacts the second sector-shaped piece, there is a squeezing force between the beveled edge and the second sector-shaped piece.

[0107] The beveled edge has a snap-in slot;

[0108] The distance from the positioning groove to the first right angle side is 1 / 4D-1 / 3D;

[0109] Wherein, D is the length of the wedge-shaped member in the Y direction.

[0110] The bottom end is provided with a limiting groove;

[0111] One end of the connecting rod close to the valve body is fixedly connected to the connecting block, and the connecting block is located in the limiting groove. The open end of the limiting groove has a blocking block, and the blocking block is used to limit the maximum displacement P of the connecting block along the Y direction in the limiting groove.

[0112] Since the temperature sensing component changes due to the influence of temperature, when the temperature sensing component senses that the temperature of the battery pack is slightly higher, but it does not need to be cooled immediately, if the controlled valve is opened, there will be unnecessary use of coolant, reducing the cooling speed of other battery packs that need to be cooled. Therefore, it is very necessary to design a cooling system that only cools battery packs with large temperature differences.

[0113] In this embodiment, if Figure 5 As shown, the wedge-shaped member is a right-angled triangular sheet of metal, and the wedge-shaped member has a first right-angled side, a second right-angled side and a hypotenuse; wherein, the first right-angled side is parallel to the first plane; the second right-angled side does not generate a force with the first sector sheet, and the hypotenuse and the second sector sheet can contact and displace relative to each other; and it satisfies that when the hypotenuse contacts the second sector sheet, there is a squeezing force between the hypotenuse and the second sector sheet. When the temperature of the battery pack is normal, the connecting block is located at one end close to the liquid outlet channel. When the temperature of the battery pack gradually increases, the connecting block and the connecting rod slowly move toward the valve body in the limiting groove. When the connecting block 1232 moves toward the valve body and is close to the valve body, the connecting rod bears the pressure of the movable end to push the wedge-shaped member toward the valve body until the positioning groove of the wedge-shaped member is fixed with the edge of the second sector sheet by snapping. When the connecting rod is subjected to the pulling force of the movable end away from the valve body, the connecting piece first displaces in the limit groove until the connecting piece is in close contact with the wedge-shaped component. The wedge-shaped component then moves away from the valve body until it is no longer in contact with the second sector-shaped piece. Under the action of the torsion spring, the second sector-shaped piece returns to its initial position.

[0114] In one embodiment, the distance from the positioning groove 122 to the first right angle side is 1 / 4D-1 / 3D, wherein D is the length of the wedge-shaped member in the Y direction, and the maximum flow of the controlled valve can be controlled by controlling the position of the positioning groove.

[0115] Embodiment 6:

[0116] The second fan-shaped blade has a protrusion at a pushing position, the pushing position is located on a side of the second fan-shaped blade facing the liquid outlet channel, and the pushing position can contact the wedge-shaped component;

[0117] The protrusion is in the shape of a triangular prism, and the cross section of the protrusion perpendicular to the side edge is an acute triangle. One side edge of the protrusion coincides with the edge of the second sector-shaped piece, and one side surface of the protrusion contacts the second sector-shaped piece.

[0118] The angle between the two force-bearing ends of the torsion spring and the center of the fixed disk is 360° / n~160°.

[0119] Since the fixed baffle and the movable baffle have a certain thickness, when the wedge-shaped component moves directly toward the valve body, there is a high probability that the valve body will be directly squeezed, thereby affecting the service life of the valve body.

[0120] In this embodiment, if Figure 6 As shown, the second fan-shaped blade has a protrusion 3322 at the pushing position, the pushing position is located on the side of the second fan-shaped piece facing the liquid outlet channel, and the pushing position can contact the wedge-shaped member; wherein the protrusion is in the shape of a triangular prism, the cross section of the protrusion perpendicular to the side edge is an acute triangle, one side edge of the protrusion coincides with the edge of the second fan-shaped piece, and one side surface of the protrusion contacts the second fan-shaped piece. By arranging a protrusion used in conjunction with the wedge-shaped member on the second fan-shaped piece, the wedge-shaped member contacts the protrusion to generate a squeezing force, thereby causing the movable baffle to rotate, changing the size of the gap between the second fan-shaped piece and the first fan-shaped piece.

[0121] In this embodiment, the present invention improves the supercharged energy storage adaptive cooling system, and the temperature sensing component is installed on the inner wall of the battery cabinet.
