[0041] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0042] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Please refer to Figure 1 and Figure 2 , which is a battery charging and cooling system provided by an embodiment of the utility model, includes a controller 11, a water pump 2, a temperature sensor 4, a suspension bracket 8, and a cooling pool 3 and a rechargeable battery 9 opened on a carrier 1.

[0044] The cooling pool 3 and the rechargeable battery 9 are both embedded in the carrier 1 . The cooling pool 3 is connected to the rechargeable battery 9 through a liquid infusion tube 7 , and the water pump 2 is arranged on the liquid infusion tube 7 .

[0045] The suspension frame 8 is disposed on the carrier 1 and is close to the rechargeable battery 9 .

[0046] The temperature sensor 4 is disposed on the rechargeable battery 9 , and the controller 11 is electrically connected to the temperature sensor 4 and the water pump 2 , respectively.

[0047] The suspension frame 8 is used to suspend the rechargeable battery 6 immersed in the rechargeable battery 9 , and the controller 11 is used to control the working state of the water pump 2 according to the temperature sensor 4 to switch the conveying state of the coolant between the cooling pool 3 and the rechargeable battery 9 .

[0048] The coolant in the cooling pool 3 and the rechargeable battery 9 can be a liquid with good heat transfer performance, flame retardancy, and insulation. For example, the coolant can be tap water or mechanical coolant, etc., and the specific heat capacity of the coolant is much higher than that of air, which can better and faster take away the heat released by the rechargeable battery 6.

[0049] It should be noted that the carrier 1 can be the ground, or a weighing cement layer between floors of a building, or other objects that can bear weight and have a certain thickness, which is not limited in this embodiment. The controller 11 can be the controller 11 that comes with the water pump 2, or it can be an independent controller 11, which is not limited here.

[0050] In addition, the delivery state may include a stop mode and multiple delivery modes. The multiple delivery modes may correspond to different liquid flow rates. When the temperature collected by the temperature sensor 4 is higher, the water pump 2 adopts a delivery mode with a higher liquid flow rate. When the temperature collected by the temperature sensor 4 is lower, the water pump 2 adopts a stop mode or a delivery mode with a lower liquid flow rate.

[0051] For example, a control table may be pre-set on the controller 11, and the corresponding relationship between the temperature range and the delivery mode may be recorded on the control table. The controller 11 obtains the current temperature collected by the temperature sensor 4, and queries the control table to determine the temperature range in which the current temperature falls, and controls the water pump 2 to work in the delivery mode corresponding to the temperature range. Alternatively, the corresponding relationship between the temperature change rate range and the delivery mode may be recorded on the control table. The controller 11 obtains the current temperature collected by the temperature sensor 4, calculates the temperature change rate based on the current temperature and the previous temperature at the previous moment, and queries the control table to determine the temperature change rate range in which the temperature change rate falls, and controls the water pump 2 to work in the delivery mode corresponding to the temperature change rate range.

[0052] In the above-mentioned battery charging and cooling system, the rechargeable battery 6 is suspended by the suspension frame 8 through the film waterproof cover 5 and then immersed in the rechargeable battery 9, so that the rechargeable battery 6 can be charged and cooled at the same time, so that the rechargeable battery 6 is kept at a low temperature. The cooling pool 3 and the rechargeable battery 9 form a coolant circulation system through the infusion tube 7 and the water pump 2 on the infusion tube 7, so that the controller 11 controls the working state of the water pump 2 according to the temperature sensor 4 set on the rechargeable battery 9, switches the delivery state of the coolant between the cooling pool 3 and the rechargeable battery 9, and timely replaces the high-temperature coolant in the rechargeable battery 9 after heat exchange with the rechargeable battery 6, so that the coolant in the rechargeable battery 9 is always kept at a low temperature. Thereby, the charging and cooling effect is greatly improved, the probability of battery combustion is reduced, and the battery explosion loss is reduced.

[0053] In addition, since the coolant of the rechargeable battery 9 for cooling the rechargeable battery 6 is always kept at a low temperature, and the rechargeable battery 6 is rapidly exchanged with the coolant over a large area, the cooling effect of the above-mentioned battery charging and cooling system is far better than that of air cooling, water cooling, etc., which greatly improves the safety of battery charging. Even if a battery charging explosion occurs, the loss is very small, and there will be no risk of mass death, mass injury, large-scale fire, etc. In addition, the liquid level control means are simple and easy, and the construction and use costs are low.

[0054] The cooling pool 3 and the rechargeable battery 9 can be hollow, rectangular parallelepiped structures made of steel bars and concrete, or they can be cylindrical or other irregular three-dimensional structures. In order to increase the cooling speed of the coolant in the cooling pool 3, the cross section of the cooling pool 3 is larger than the cross section of the rechargeable battery 9, and the depth of the cooling pool 3 is smaller than the depth of the rechargeable battery 9. In this way, the heat dissipation area of ​​the coolant in the cooling pool 3 is larger and the heat dissipation speed is faster.

[0055] For example, the depth of the rechargeable battery 9 may be 1.2 meters, and the total area of ​​the cross section may be 8m 2 The depth of the cooling pool 3 can be 0.8 meters, and the total cross-sectional area can be 12m 2The above numerical values ​​are only examples and are not limited to specific implementations.

[0056] In order to further increase the cooling speed of the coolant in the cooling pool 3 and ensure that the coolant pumped to the rechargeable battery 9 by the water pump 2 can be cooled, a cooling device can be further provided on the cooling pool 3 to cool the coolant in the cooling pool 3.

[0057] There may be multiple cooling devices, which are arranged on the wall of the cooling pool 3. The cooling device may include a cartridge and an automatic spraying device. The cartridge may be filled with liquid coolant. The automatic spraying device is electrically connected to a temperature sensor arranged in the cooling pool 3. The automatic spraying device sprays the liquid coolant in the cartridge to the cooling pool 3 according to the temperature sensor. For example, when the temperature is greater than a set value, or the temperature increase rate is greater than a set threshold, the automatic spraying device sprays the liquid coolant in the cartridge to the cooling pool 3.

[0058] The cooling device may also be an air conditioning heat rejector or an air conditioner, which is not limited in this embodiment.

[0059] In order to quickly control the coolant of the rechargeable battery 9 to the target cooling temperature when the temperature of the coolant of the rechargeable battery 9 is high, the concept of discharging the high-temperature coolant of the rechargeable battery 9 and injecting the low-temperature coolant simultaneously is introduced into the battery charging and cooling system. The method of realizing the above concept can be flexibly set. For example, the cooling pool 3 and the rechargeable battery 9 are also connected by a drain pipe. The drain pipe is used to discharge the coolant in the rechargeable battery 9 into the cooling pool 3. The drain pipe can be provided with a water pump 2 or a valve electrically connected to the temperature sensor 4 to control the drainage state according to the temperature of the coolant of the rechargeable battery 9 collected by the temperature sensor 4. A drainage channel can also be provided between the cooling pool 3 and the rechargeable battery 9. The drainage channel is also provided with a valve electrically connected to the temperature sensor 4. The valve switches between the closed and open states according to the temperature of the coolant of the rechargeable battery 9 collected by the temperature sensor 4. The above two methods are only an example and are not limited in this embodiment.

[0060] In order to reduce the construction cost while achieving the discharge of high-temperature coolant and the injection of low-temperature coolant from the rechargeable battery 9 at the same time, and to avoid the situation where the coolant of the rechargeable battery 9 is exhausted and the temperature cannot be lowered, it can be illustrated by referring to Figure 3 and Figure 4 A plurality of overflow ports 10 are provided between the cooling pool 3 and the rechargeable battery 9 . The plurality of overflow ports 10 have the same height. The height of the overflow ports 10 is greater than the immersion depth of the rechargeable battery 6 in the rechargeable battery 9 , and the total natural flow of the overflow ports 10 is greater than the maximum flow of the water pump 2 .

[0061] Among them, the height value of the overflow port 10 from the bottom of the rechargeable battery 9 can be adaptively adjusted according to the size of the battery. For example, the height of the overflow port 10 from the bottom of the rechargeable battery 9 can be about 0.8 meters or 0.6 meters. The above values ​​are only examples and are not limited to their specific implementation.

[0062] Through the above arrangement, when the coolant in the rechargeable battery 9 is higher than the overflow 10, it flows back to the cooling pool 3 through the overflow 10 for cooling, and because the total natural flow of the overflow 10 is greater than the maximum flow of the water pump 2, the coolant with a higher temperature in the rechargeable battery 9 flows back to the cooling pool 3 in time through the overflow 10 for cooling, ensuring that there is always coolant in the cooling pool 3 that has been cooled, avoiding the situation where the water pump 2 cannot pump coolant to cool the rechargeable battery 9 due to the absence of coolant in the cooling pool 3. At the same time, by the height of the overflow 10 being greater than the immersion depth of the rechargeable battery 6 in the rechargeable battery 9, it is ensured that the heat-generating part of the rechargeable battery 6 can completely enter the rechargeable battery 9 for cooling, avoiding the situation where some areas cannot exchange heat and cool, and improving the cooling effect. In addition, it is easy to ensure that the height of the coolant in the rechargeable battery 9 is constant, avoiding the situation where the coolant level is too high to submerge the control part of the rechargeable battery 6 due to the malfunction of the water pump 2.

[0063] Since the bottom layer coolant temperature is slightly lower than the surface layer temperature, in the process of coolant circulation between the rechargeable battery 9 and the cooling pool 3 under the action of the water pump 2, in order to make the low-temperature coolant in the cooling pool 3 enter the rechargeable battery 9 first, and to make the higher-temperature coolant in the rechargeable battery 9 be discharged from the rechargeable battery 9 into the cooling pool 3 for cooling first. Figure 3 and Figure 4 The distance between the water inlet 710 of the infusion pipe 7 connected to the water pump 2 and the bottom of the cooling pool 3 can be 0.1 meters, and the distance between the water outlet 720 of the infusion pipe 7 and the bottom of the rechargeable battery 9 can be 0.1 meters. The water outlet 720 of the infusion pipe 7 is far away from the overflow port. Therefore, when the water pump 2 is working, it can ensure that the bottom coolant with a lower temperature in the cooling pool 3 is first pumped into the rechargeable battery 9, and at the same time, it can avoid sucking the bottom sediment of the cooling pool 3. And through the setting of the water outlet 720 of the infusion pipe 7, it is ensured that most of the coolant in the rechargeable battery 9 participates in the cooling cycle.

[0064] In the above manner, the distance between the water inlet 710 of the infusion tube 7 and the bottom of the cooling pool 3, and the distance between the water outlet 720 of the infusion tube 7 and the bottom of the rechargeable battery 9 can be adjusted, for example, to 0.2 or 0.15, which is not limited in this embodiment.

[0065] In order to prevent the coolant in the rechargeable battery 9 from entering the rechargeable battery 6, refer to Figure 3 The battery charging and cooling system also includes a waterproof cover 5, which is used to wrap the rechargeable battery 6 suspended on the suspension frame 8.

[0066] The waterproof cover 5 can be made of a material with high strength, heat resistance and good heat transfer performance, so that the waterproof cover 5 has the properties of high strength, heat resistance and good heat transfer performance. For example, it can be made of a temperature-resistant plastic film, PEN film And other materials.

[0067] Since the rechargeable battery 6 generally includes a battery core and an electronically controlled charging device, the battery core has a higher temperature. Therefore, in order to better wrap the rechargeable battery 6 for waterproof protection and facilitate charging, referring to the figure, the waterproof cover 5 includes a battery cover and an electronically controlled cover located above the battery cover. The battery cover is used to wrap the battery core of the rechargeable battery 6, and the electronically controlled cover is used to wrap the electronically controlled charging device of the rechargeable battery 6. When the rechargeable battery 6 is immersed in the coolant of the rechargeable battery 9, the battery cover and the battery core in the battery cover are immersed.

[0068] The waterproof cover 5 may be in the shape of a hollow waterproof pocket, and its shape and size are adapted to the rechargeable battery 6. The waterproof cover 5 and the electric control cover may be provided with an opening, or a waterproof charging tube through which the charging cable passes, or a charging hole through which the charging cable passes (the charging hole may also be provided with a waterproof sealing ring) to prevent the coolant from entering the rechargeable battery 6 from the electric control cover.

[0069] When the electric control sleeve is opened, the height of the waterproof sleeve 5 is greater than the height of the battery to prevent the coolant from entering the rechargeable battery 6 from the electric control sleeve, thereby ensuring the safe operation of the charging part of the rechargeable battery 6 (ie, the electric control charging device).

[0070] For example, taking the rechargeable battery 6 mainly including vertical batteries and horizontal batteries, the film waterproof cover 5 is adapted thereto, the height of the waterproof cover 5 is 0.3 meters greater than the height of the rechargeable battery 6, and the inner dimension of the waterproof cover 5 is 0.1 meters larger than the battery to facilitate wrapping the rechargeable battery 6.

[0071] Through the above arrangement, the portion of the waterproof cover 5 wrapped with the rechargeable battery 6 immersed in the coolant of the rechargeable battery 9 is subjected to the liquid pressure and is tightly attached to the rechargeable battery 6 with almost no gap, so that the rechargeable battery 6 can better exchange heat with the coolant, ensuring the cooling of the rechargeable battery 6.

[0072] In order to prevent the coolant in the rechargeable battery 9 and the fragments of the rechargeable battery 6 from splashing out of the rechargeable battery 9 and causing harm to people, animals, property, etc. in extreme situations such as combustion or explosion of the rechargeable battery 6, the rechargeable battery 9 includes a cell body and a protective wall. The cell body is arranged in the carrier 1, and the protective wall is located on the carrier 1 and is circumferentially arranged around the cell body.

[0073] Taking the carrier 1 as the ground as an example, the cell body of the rechargeable battery 9 is built under the ground, and a protective wall surrounding the cell body is built on the ground.

[0074] The height of the protective wall can also be flexibly set, for example, it can be 0.3 meters or 0.4 meters, which is not limited in this embodiment. According to the invention, the protective wall can be constructed of steel bars and concrete.

[0075] Through the structure of the above-mentioned rechargeable battery 9, the protective wall protruding from the carrier 1 (such as the ground) can block the coolant, burning fragments, etc. spread by the explosion when the rechargeable battery 6 explodes, thereby ensuring the safety of people and property around the rechargeable battery 9.

[0076] The structure of the suspension frame 8 can also be flexibly set. For example, it can be a suspension rod overlapped on the protective wall of the rechargeable battery 9, or it can be an independent optional structure. The above method is only an example, and its specific implementation is not limited.

[0077] In order to improve the stability of the rechargeable battery 6 during charging, the rechargeable battery 6 is prevented from falling into the rechargeable battery 9 due to unstable suspension. A plurality of suspensions can be arranged near each rechargeable battery 9, and the suspension frame 8 includes a bracket, a suspension rod and a suspension lock.

[0078] The bracket is disposed on the carrier 1 and is close to the rechargeable battery 9 .

[0079] The suspension rod is arranged at a position where the bracket is far away from the carrier 1 .

[0080] One end of the suspension lock is arranged on the suspension rod, and the other end of the suspension lock is used to lock the rechargeable battery 6.

[0081] Among them, one end of the suspension lock can be fixed on the suspension rod by welding, threading, bonding, etc., and the other end of the suspension lock is a lock structure, which is locked with the waterproof cover 5 or the rechargeable battery 6 through the lock structure.

[0082] Through the above arrangement, the bracket provides a stabilizing force for the suspension rod, and the suspension rod provides a supporting force for the suspension lock and the rechargeable battery 6 suspended on the suspension lock to prevent the rechargeable battery 6 from shaking. At the same time, the suspension lock locks the rechargeable battery 6 to prevent the rechargeable battery 6 from slipping or being stolen, further improving the charging safety.

[0083] In order to facilitate charging of the rechargeable battery 6, a charging socket and / or a charger may be provided on the suspension frame 8, and the charging socket and / or the charger may be electrically connected to a charging pile buried in the carrier 1, or a charging cabinet provided near the rechargeable battery 9. Thus, when the rechargeable battery 6 has its own charger, it can be connected to the charging socket for charging, and when the rechargeable battery 6 does not have a charger, it can be connected to the charger on the suspension frame 8 for charging, so as to meet different charging requirements.

[0084] In order to further improve the safety of the rechargeable battery 6 during charging and avoid confusion in taking the rechargeable battery 6, the battery charging and cooling system introduces the concept of user identification locking for charging and unlocking for taking the rechargeable battery 6. The battery charging and cooling system also includes an identification device, and the controller 11 is respectively connected to the suspension lock and the identification device for communication.

[0085] The identification device is used for the user to input a charging request or lock information.

[0086] The controller 11 is further configured to select an idle suspension lock according to a charging request transmitted by the identification device, and to switch the suspension lock to locked or unlocked according to lock information transmitted by the identification device.

[0087] For example, the suspension lock can report the working status when locked or unlocked, or report the working status regularly. The controller 11 determines the working suspension locks and the idle suspension locks according to the working status reported by each suspension lock. When charging is needed, the user inputs a charging request to the controller 11 through the identification device, and the controller 11 responds by transmitting the idle suspension locks at the current moment to the identification device, and the identification device displays the idle suspension locks for the user to select.

[0088] When the user selects the suspension lock, the identification device can use the user information as the lock information, or display the lock information input box to prompt the user to input the lock information. The identification device transmits the lock information and the suspended suspension lock to the controller 11. The controller 11 stores the lock information and the suspended suspension lock in a corresponding relationship, and controls the suspended suspension lock to be unlocked. When the user hangs the rechargeable battery 6 on the suspended suspension lock, locks it and starts charging, the suspension lock is locked to lock the rechargeable battery 6, and returns the locking information to the controller 11, and the controller 11 updates the working status of the suspension lock.

[0089] When charging is completed, the user uploads the lock information to the controller 11 through the identification device, and the controller 11 queries the suspension lock corresponding to the lock information, sends an unlocking instruction to the suspension lock, and stops charging. When the suspension lock receives the unlocking instruction, it unlocks and releases the rechargeable battery 6, and sends the unlocking status back to the controller 11, and the controller 11 updates the working status of the suspension lock.

[0090] The lock information may be, but is not limited to, a digital password, a face password, or a fingerprint password, etc., which is not limited in this embodiment.

[0091] Based on the same utility model concept as the above battery charging and cooling system, a charging system is provided, referring to Figure 5 , including a rechargeable battery 6 and a battery charging and cooling system as provided above.

[0092] There may be multiple battery charging and cooling systems, and the structure and technical effects of the battery charging and cooling systems can be found in the above description, which will not be described in detail in this embodiment.

[0093] The charging system may further include a charging pile buried in the carrier 1 , or a charging cabinet arranged near the rechargeable battery 9 . One charging pile or charging cabinet may charge multiple rechargeable batteries 6 .

[0094] In a certain area, multiple groups of battery charging and cooling systems of the charging system can be arranged to meet the large number of battery charging needs in crowded places. In addition, when a charging accident occurs in a group of battery charging and cooling systems, the remaining battery charging and cooling systems can still be used, thereby meeting the charging needs and only causing local losses.

[0095] The battery charging and cooling system and the charging system provided by the embodiment of the utility model at least have the following beneficial effects:

[0096] (1) Good cooling effect: The cooling pool is used to circulate and replace the coolant of the rechargeable battery and cool it down, so that the coolant of the rechargeable battery is kept at a low temperature and the liquid of the rechargeable battery is circulated to cool down the rechargeable battery, which greatly improves the cooling effect of the rechargeable battery;

[0097] (2) Low construction cost: It can be built by relying on ground, concrete and water cooling. The construction, use and maintenance costs are very low and easy to promote;
