Description

Technical Field

[0001] The present application relates to the technical field of power batteries, and in particular to fast-charging batteries and modules thereof. Background Art

[0002] With the rapid development of lithium-ion batteries and their large-scale application in new energy vehicles and energy storage fields, the operating conditions requirements for lithium-ion batteries are becoming increasingly stringent. Not only are the batteries required to work over the full temperature range, but they are also required to be able to charge quickly and stably at high rates.

[0003] In the prior art, a heating film is attached to the surface of the battery cell, and an insulating isolation film is set on the surface of the heating film to seal the entire heating element to avoid direct contact between the heating element and the battery cell. The isolation film improves the insulation properties of the battery, and the heating element is closely fitted to achieve overall battery heating to address the problems of lithium batteries having difficulty working at low temperatures and slow charging.

[0004] However, since the entire heating element is sealed and the battery cell is located inside the battery, when the temperature of the battery cell rises to the point of affecting the charging and discharging efficiency during charging and discharging, the battery cannot be cooled, that is, the charging and discharging temperature of the battery cannot be controlled within a reasonable range. In addition, when the heating film function of the fast charging module is enabled, the heat distribution is uneven, and the charging and discharging temperature of the battery cannot be controlled within a reasonable range, resulting in a risk of thermal runaway. Summary of the invention

[0005] Based on this, it is necessary to provide a fast charging battery and its module to address the problem that the charging and discharging temperature of the battery cannot be controlled within a reasonable range in the prior art.

[0006] A fast-charge battery, comprising:

[0007] case;

[0008] A plurality of battery cells are located in the housing, and the plurality of battery cells are sequentially spaced apart along the thickness direction thereof;

[0009] A plurality of groups of first tabs, corresponding to and connected to the plurality of battery cells one by one, the tabs extending out of the same side of the shell, and used for charging and discharging the battery cells;

[0010] A temperature increasing module, the temperature increasing module is connected to the battery cell and is used to heat the battery cell;

[0011] A temperature control component is connected to the battery core and is used to control the temperature of the battery core.

[0012] During the actual charging and discharging process of the above-mentioned fast-charging battery, when it is initially started and used under low-temperature conditions, the charging and discharging efficiency is low due to the low temperature of the battery and the surrounding area. Therefore, the battery cell is heated up through the heating module to improve the charging and discharging efficiency. When the battery temperature rises rapidly or the temperature rises to affect the battery charging and discharging efficiency, the temperature change rate of the battery cell is adjusted through the temperature control component, or the temperature of the battery cell is directly lowered to make the battery cell temperature at the optimal operating temperature, thereby ensuring that the battery charging and discharging temperature is controlled within a reasonable range, thereby ensuring the charging and discharging efficiency of the battery cell.

[0013] In one embodiment, the temperature increasing module comprises a plurality of heating elements, wherein the heating element is connected to at least one of the battery cells, and the battery cell is connected to at least one of the heating elements.

[0014] In this embodiment, a heating element may be connected to only one battery cell, or a heating element may be located between two adjacent battery cells. Along the direction of arrangement of the battery cells, every two adjacent battery cells are simultaneously connected to a heating element, so that one heating element can heat two battery cells at the same time, saving the number of heating elements and at the same time ensuring the stable heating requirement of each battery cell.

[0015] In one embodiment, the heating element includes a heating film and a second pole ear, the heating film is connected to at least one of the battery cells, the battery cell is connected to at least one of the heating films, and the second pole ear is connected to the heating film for energizing the heating film.

[0016] In one embodiment, the temperature control component includes a plurality of heat sinks, wherein the heat sinks are located between two adjacent battery cells, the heating element is located between two adjacent battery cells, there is one heating element between two adjacent heat sinks, and there is one heat sink between two adjacent heating elements.

[0017] In one embodiment, the heat sink is connected to the shell, and the shell is a metal shell.

[0018] In one embodiment, the temperature control assembly further includes a first tube, a second tube and an evaporator;

[0019] One end of the first tube is in communication with the interior of the evaporator, and the other end is in communication with the second tube, and the first tube is partially disposed around the first electrode lug;

[0020] One end of the second tube is in communication with the interior of the evaporator, and the other end is in communication with the first tube, and the second tube is partially disposed around one end of the battery cell away from the first electrode tab along the first direction;

[0021] The evaporator is filled with a heat exchange medium, and the first direction is perpendicular to the thickness direction of the battery core.

[0022] In this embodiment, the heat exchange medium inside the evaporator reaches the first pole ear through the first tube, absorbs excess heat at the first pole ear with a higher temperature and evaporates into gas, then flows through the second tube through the end of the fast-charge battery away from the first pole ear in the first direction, releases heat and becomes liquid, and returns to the inside of the evaporator. The evaporator transports the liquid to the first pole ear with a higher temperature again, and circulates the temperature to cool down. The state change of the low-boiling-point heat exchange medium in the first tube and the second tube realizes the temperature balancing function of the overall fast-charge battery. Specifically, a power device, such as a pump, can be added to the evaporator, the first tube or the second tube to provide power for the flow of the heat exchange medium.

[0023] In one embodiment, the vaporization temperature of the heat exchange medium is 30°C to 70°C, and the liquefaction temperature of the heat exchange medium is -108°C to 30°C. This ensures that the heat exchange medium inside the evaporator reaches the first pole ear through the first tube, absorbs excess heat at the first pole ear with a higher temperature and evaporates into gas, then flows through the second tube through the end of the fast-charge battery away from the first pole ear in the first direction, releases heat and becomes liquid, and returns to the inside of the evaporator. The evaporator transports the liquid to the first pole ear with a higher temperature again, circulates and cools down, and realizes the temperature balancing function of the overall fast-charge battery through the state transition of the low-boiling-point heat exchange medium in the first tube and the second tube.

[0024] In one embodiment, the heat exchange medium is one of acetone, ether and pentane. The heat exchange medium inside the evaporator passes through the first tube to reach the first pole ear, absorbs excess heat at the first pole ear with a higher temperature and evaporates into gas, then passes through the second tube and flows through the end of the fast-charge battery away from the first pole ear in the first direction, releases heat and becomes liquid, and returns to the inside of the evaporator. The evaporator transports the liquid to the first pole ear with a higher temperature again, and the temperature is circulated and cooled. The temperature balancing function of the overall fast-charge battery is achieved through the state change of the low-boiling-point heat exchange medium in the first tube and the second tube.

[0025] In one embodiment, the second electrode tab extends out of the housing at one end thereof away from the first electrode tab along a first direction.

[0026] An embodiment of the present application further provides a fast-charge battery module, wherein the fast-charge battery module includes a plurality of the fast-charge batteries;

[0027] A plurality of the fast-charging batteries are connected in series and / or in parallel.

[0028] During the actual charging and discharging process of the above-mentioned fast-charging battery module, when it is initially started and used under low-temperature conditions, the charging and discharging efficiency is low due to the low temperature of the battery and the surrounding area. Therefore, the battery cell is heated up through the heating module to improve the charging and discharging efficiency. When the battery temperature rises rapidly or the temperature rises to affect the battery charging and discharging efficiency, the temperature change rate of the battery cell is adjusted through the temperature control component, or the temperature of the battery cell is directly lowered to make the battery cell temperature at the optimal operating temperature, thereby ensuring that the battery charging and discharging temperature is controlled within a reasonable range, thereby ensuring the charging and discharging efficiency of the battery cell of the fast-charging battery module.

[0046] Refer to Figure 1, which shows a structural schematic diagram of a fast-charging battery 100 in an embodiment of the present application. The fast-charging battery 100 provided in an embodiment of the present application includes: a shell 110, a plurality of battery cells 120, a plurality of groups of first pole ears 130, a temperature rising module 140 and a temperature control component 150.

[0047] In the above-mentioned fast-charge battery 100, a plurality of battery cells 120 are located in the shell 110, and the plurality of battery cells 120 are arranged in sequence along the thickness direction thereof. A plurality of groups of first tabs 130 correspond to and are connected to the plurality of battery cells 120 one by one, and the tabs extend out of the same side of the shell 110, and are used to charge and discharge the battery cells 120. The heating module 140 is connected to the battery cell 120 for heating the battery cell 120. The temperature control component 150 is connected to the battery cell 120 for controlling the temperature of the battery cell 120.

[0048] During the actual charging and discharging process of the above-mentioned fast charging battery 100, when it is initially started and used under low temperature conditions, the charging and discharging efficiency is low due to the low temperature of the battery and the surrounding area. Therefore, the battery cell 120 is heated by the heating module 140 to improve the charging and discharging efficiency. When the battery temperature rises rapidly or the temperature rises to affect the battery charging and discharging efficiency, the temperature control component 150 is used to adjust the speed of change of the battery cell 120 temperature, or directly reduce the temperature of the battery cell 120, so that the temperature of the battery cell 120 is at the optimal operating temperature, ensuring that the charging and discharging temperature of the battery is controlled within a reasonable range, thereby ensuring the charging and discharging efficiency of the battery cell 120.

[0049] 1 and 2 , in one embodiment, the temperature increasing module 140 includes a plurality of heating elements 141 . The heating element 141 is connected to at least one battery cell 120 , and the battery cell 120 is connected to at least one heating element 141 .

[0050] In this embodiment, a heating element 141 may be connected to only one battery cell 120, or a heating element 141 may be located between two adjacent battery cells 120. Along the arrangement direction of the battery cells 120, every two adjacent battery cells 120 are simultaneously connected to a heating element 141, so that one heating element 141 can heat two battery cells 120 at the same time, saving the number of heating elements 141 and at the same time ensuring the requirement of stable heating of each battery cell 120.

[0051] Referring to Figures 1 and 2, in one embodiment, the heating element 141 includes a heating film 142 and a second pole ear 143, the heating film 142 is connected to at least one battery cell 120, the battery cell 120 is connected to at least one heating film 142, and the second pole ear 143 is connected to the heating film 142, and is used to energize the heating film 142, so as to realize the heating of the heating film 142 by energizing, and then the battery cell 120 is heated to improve the charging and discharging efficiency. When the temperature of the fast-charging battery 100 rises rapidly or the temperature rises to affect the charging and discharging efficiency of the fast-charging battery 100, the temperature control component 150 is used to adjust the speed of change of the temperature of the battery cell 120, or directly reduce the temperature of the battery cell 120, so that the temperature of the battery cell 120 of the fast-charging battery 100 is at the optimal operating temperature, ensuring that the charging and discharging temperature of the battery is controlled within a reasonable range, thereby ensuring the charging and discharging efficiency of the battery cell 120 of the fast-charging battery 100.

[0052] Referring to Figures 1 and 2, in one embodiment, the temperature control component 150 includes a plurality of heat sinks 151, the heat sink 151 is located between two adjacent battery cells 120, the heating element 141 is located between two adjacent battery cells 120, there is a heating element 141 between two adjacent heat sinks 151, and there is a heat sink 151 between two adjacent heating elements 141, thereby forming a structure in which the battery cell 120, the heating film 142, the battery cell 120, the heat sink 151, the battery cell 120, and the heating film 142 are arranged in sequence in a circular manner along the thickness direction of the battery cell 120, thereby increasing the contact area between the heating film 142 and the heat sink 151 and the battery cell 120, thereby improving the heating and heat dissipation efficiency, ensuring the temperature stability of the battery cell 120, and saving the heating film 142 and the heat sink 151.

[0053] Referring to FIG. 1 and FIG. 2 , in one embodiment, the heat sink 151 is connected to the housing 110, and the housing 110 is a metal housing, so that the heat sink 151 can transfer the temperature of the battery cell 120 to the metal housing, and dissipate heat through the metal housing, thereby effectively increasing the heat dissipation performance of the overall fast-charge battery 100. With the structure that the battery cell 120, the heating film 142, the battery cell 120, the heat sink 151, the battery cell 120, and the heating film 142 are arranged in a circular pattern in sequence along the thickness direction of the battery cell 120, the contact area of ​​the heating film 142 and the heat sink 151 with the battery cell 120 is increased, thereby improving the heating and heat dissipation efficiency, ensuring the temperature stability of the battery cell 120, and saving the heating film 142 and the heat sink 151. The metal heat sink 151 used inside the fast-charge battery 100 is used to increase the overall heat dissipation of the fast-charge battery 100, which can effectively transfer the heat of the fast-charge battery 100 during high-rate charging to the metal housing 110 and dissipate it through the metal housing 110. While having a heating function, it can effectively balance the heat distribution between the first pole ear 130 and the bottom of the fast-charging battery 100.

[0054] Referring to FIG. 1 and FIG. 2 , in one embodiment, the temperature control assembly 150 further includes a first tube 152, a second tube 153, and an evaporator 154. One end of the first tube 152 is in communication with the interior of the evaporator 154, and the other end is in communication with the second tube 153. The first tube 152 is partially disposed around the first pole tab 130. One end of the second tube 153 is in communication with the interior of the evaporator 154, and the other end is in communication with the first tube 152. The second tube 153 is partially disposed around one end of the battery cell 120 away from the first pole tab 130 along the first direction OX. The interior of the evaporator 154 is filled with a heat exchange medium, and the first direction OX is perpendicular to the thickness direction of the battery cell 120. In this embodiment, the heat exchange medium inside the evaporator 154 reaches the first pole ear 130 through the first tube 152, absorbs excess heat at the first pole ear 130 with a higher temperature and evaporates into gas, then flows through the second tube 153 through the end of the fast-charge battery 100 away from the first pole ear 130 along the first direction OX, releases heat and becomes liquid, and returns to the inside of the evaporator 154, and the evaporator 154 transports the liquid to the first pole ear 130 with a higher temperature again, circulates and cools down, and realizes the temperature balancing function of the overall fast-charge battery 100 through the state transition of the low-boiling-point heat exchange medium in the first tube 152 and the second tube 153, avoiding the concentration of heat inside the fast-charge battery 100 and affecting the charge and discharge cycle performance of the fast-charge battery 100. Specifically, a power device, such as a pump, can be added to the evaporator 154, the first tube 152 or the second tube 153 to provide power for the flow of the heat exchange medium.

[0055] Specifically, a third tube may be added, one end of which is connected to the second tube 153, and the other end of which is connected to the first tube 152. The third tube is a straight tube or a hose to achieve the connection between the first tube 152 and the second tube 153 in a curved layout after they are arranged along the first direction OX. By splitting the pipeline into three parts, a better pipeline layout is achieved, and the circulation path of the heat exchange medium is optimized.

[0056] Specifically, the vaporization temperature of the heat exchange medium is 30°C to 70°C, and the liquefaction temperature of the heat exchange medium is -108°C to 30°C. Thus, the heat exchange medium inside the evaporator 154 can reach the first pole ear 130 through the first tube 152, absorb excess heat at the first pole ear 130 with a higher temperature and evaporate into gas, and then flow through the second tube 153 through the end of the fast-charge battery 100 away from the first pole ear 130 along the first direction OX, release heat to become liquid, and return to the inside of the evaporator 154, and the evaporator 154 transports the liquid to the first pole ear 130 with a higher temperature again, and circulates and cools down. The state change of the low-boiling-point heat exchange medium in the first tube 152 and the second tube 153 realizes the temperature balancing function of the overall fast-charge battery 100, avoiding the concentration of heat inside the fast-charge battery 100 and affecting the charge and discharge cycle performance of the fast-charge battery 100.

[0057] In one embodiment, the heat exchange medium is one of acetone, ether and pentane. The heat exchange medium can also be other low-boiling-point liquids. The heat exchange medium passes through the first tube 152 inside the evaporator 154 to reach the first pole ear 130, absorbs excess heat at the first pole ear 130 with a higher temperature and evaporates into gas, and then flows through the second tube 153 through the fast-charge battery 100 along the first direction OX away from the end of the first pole ear 130, releases heat and becomes liquid, and returns to the inside of the evaporator 154. The evaporator 154 transports the liquid to the first pole ear 130 with a higher temperature again, and circulates and cools down. The state transition of the low-boiling-point heat exchange medium in the first tube 152 and the second tube 153 realizes the temperature balancing function of the overall fast-charge battery 100, avoiding the concentration of heat inside the fast-charge battery 100 and affecting the charge and discharge cycle performance of the fast-charge battery 100.

[0058] Referring to Figures 1 and 2, in one embodiment, the second pole ear 143 extends out of the shell 110 along the first direction OX away from one end of the first pole ear 130, as shown in Figure 3, so that the first section and the second section respectively extend out of the shell 110 on both sides of the first direction OX, so that the overall structure is relatively neat, the first pole ear 130 on one side is used for charging and discharging the battery cell 120, and the second pole ear 143 on the other side is used to energize the heating film 142, so that the charging and discharging and heating circuits of the battery cell 120 do not interfere with each other, thereby improving the stability of the entire fast-charging battery 100.

[0059] Specifically, the shell 110 is a cylindrical shell 110 or a cubic shell 110 with an axis along the first direction OX, or may be a shell 110 of other shapes. The specific form of the shell 110 is not described in detail herein.

[0060] An embodiment of the present application further provides a fast-charging battery module, and the fast-charging battery module includes a plurality of fast-charging batteries 100 .

[0061] A plurality of fast-charge batteries 100 are connected in series and / or in parallel.

[0062] During the actual charging and discharging process of the above-mentioned fast-charging battery module, when it is initially started and used under low-temperature conditions, the charging and discharging efficiency is low due to the low temperature of the battery and the surrounding area. Therefore, the battery cell 120 is heated by the heating module 140 to improve the charging and discharging efficiency. When the battery temperature rises rapidly or the temperature rises to affect the battery charging and discharging efficiency, the temperature control component 150 is used to adjust the speed of change of the battery cell 120 temperature, or the temperature of the battery cell 120 is directly lowered to keep the temperature of the battery cell 120 at the optimal operating temperature, thereby ensuring that the charging and discharging temperature of the battery is controlled within a reasonable range, thereby ensuring the charging and discharging efficiency of the battery cell 120 of the fast-charging battery module.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
