Description

Technical Field

[0001] The present invention relates to a cycle test device, and more particularly, to a cycle test device for secondary batteries.

[0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2023-0139822 filed on October 18, 2023, and all the contents disclosed in the literature of the Korean patent application are included as part of this specification.

Background Art

[0003] A constant temperature chamber is used to test the service life of a product under certain temperature conditions such as a high temperature environment or a low temperature environment.

[0004] A cycler device is used for the cycle test of secondary batteries. As a post-process device for secondary batteries, the cycler device is used for battery performance and life tests.

[0005] The cycler has a space part for accommodating the battery to be tested and includes an air conditioner for adjusting and maintaining the temperature in the space part. Also, the battery accommodated in the space part is electrically connected to a charger for charge and discharge performance tests.

[0006] Normally, the air conditioner of the cycler is provided to perform a constant temperature operation to maintain the temperature in the space part at a set temperature during the test period.

[0007] The air conditioner includes a refrigerator including a cooling heat exchanger, a heater, and a circulation fan. The air circulated by the circulation fan is primarily dehumidified through the cooling heat exchanger, heated by the heat supplied from the heater after being cooled, and then supplied to the space part.

[0008] That is, a convection method is applied to the constant temperature chamber for the cycle test of secondary batteries, in which the air circulating inside the space part is cooled and heated to control the temperature inside the chamber.

[0009] However, the heat transfer coefficient (h) due to natural convection of air is 5-50 W / m 2 The temperature is K, and the heat transfer coefficient (h) due to forced convection is 25-250 W / m 2 The temperature is around K, and conventional cycle test chambers are systems that control the temperature inside the chamber through heat transfer by forced convection of circulating air, but they have the problem of insufficient energy conversion efficiency.

[0010] Furthermore, in the case of test equipment that requires high temperature control performance (cooling / heating rate), higher-spec refrigerators and heaters are currently being used.

[0011] In particular, in the case of convective heat transfer, the larger the internal space of the chamber, the lower the probability that the heat source supplied for temperature control and the object whose temperature is being controlled will meet, resulting in lower heat transfer efficiency. In other words, air flowing away from the object being heated / cooled cannot participate in heat transfer, which causes low energy efficiency.

[0012] Furthermore, in the case of refrigerators, there are limitations to active control compared to heaters, and they are designed to maintain a cooling performance above a certain level or close to the design value. As a result, regardless of the heat load generated inside the chamber, the refrigerator and heater are operated to maintain the chamber temperature, which leads to a problem of low thermal efficiency, given the characteristics of equipment that is tested over a long period of time. [Overview of the project] [Problems that the invention aims to solve]

[0013] The present invention aims to provide a cycle test apparatus capable of maintaining and adjusting the temperature of a test chamber using convective heat transfer and conductive heat transfer methods.

[0014] Furthermore, the present invention aims to provide a cycle test apparatus that can improve thermal efficiency and enhance control responsiveness by first controlling the temperature of the space using a convection method and directly cooling the chamber wall of the space using a conduction method in response to fluctuations in the heat load within the space.

[0015] Furthermore, the present invention aims to provide a cycle test apparatus that can individually control the temperature of multiple spatial sections.

[0030] Furthermore, the multiple partitions may include a pair of opposing side walls and a rear wall connecting the pair of side walls. For example, multiple flow holes can be formed in either one of the side walls or the rear wall, and the air that has passed through the evaporator and the fan can flow into the space through the flow holes.

[0031] Furthermore, the second temperature control unit can be provided in one of the upper and lower walls that connect a pair of side walls among the multiple partition walls.

[0038] Furthermore, the control unit may be configured to drive the first temperature control unit during constant temperature operation and the second temperature control unit during cooling operation for each space.

[0046] A cycle test apparatus according to one embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0047] Furthermore, regardless of the reference numerals used in the drawings, identical or corresponding components will be assigned the same or similar reference numerals, and redundant explanations for them will be omitted. For the sake of clarity, the size and shape of each component shown in the illustrations may be exaggerated or reduced.

[0048] Figure 1 is a schematic perspective view of a cycle test apparatus (1) related to one embodiment of the present invention, Figure 2 is a schematic configuration diagram of the cycle test apparatus shown in Figure 1, and Figure 3 is a schematic perspective view of the chambers constituting the cycle test apparatus.

[0049] The cycle test apparatus (1) includes a chamber (100) having a space (101) for housing a battery (B) and a plurality of partition walls (110) forming the space (101). The space (101) may be a test space in which the cycle test of the battery (B) is performed.

[0050] Furthermore, the cycle test device (1) may include an operating unit (410) for inputting the device's ON / OFF status and the test temperature inside the chamber (100), and a display unit (420) for displaying operational information including the test temperature.

[0051] Figure 4 is a schematic diagram of the cycle test apparatus shown in Figure 3.

[0052] The battery (B) may be a rechargeable battery, and may be of various types, such as pouch-type, cylindrical, or rectangular. Furthermore, multiple batteries (B) can be housed within the space (101), and batteries (B) housed within the same space (101) can undergo cycle testing under the same temperature conditions.

[0053] Furthermore, the battery (B) can be housed in the space (101) while mounted on the charging jig (700), and can be charged through the charging jig (700). For this reason, the chamber (100) can be provided with a connector (600) for electrically connecting to the charging jig (700).

[0054] Furthermore, the cycle test device (1) may include a charge / discharge unit (1000) for charging the battery (B) through a charging jig. In this case, the charge / discharge unit (1000) may be located inside the cycle test device (1), or it may be located outside the cycle test device (1) and electrically connected to a connector (600) inside the test device (1) via a cable or the like.

[0055] Furthermore, the test apparatus (1) may include multiple chambers (100). Figure 1 shows two chambers (100, 100') arranged vertically / horizontally, but the number of chambers (100) can be determined in various ways.

[0056] The cycle test apparatus (1) includes a first temperature control unit (200) which includes a first refrigerator (210) provided to supply air to the space (101) and to adjust the temperature of the supplied air.

[0057] The first temperature control unit (200) can be configured to adjust the temperature of the space (101) by air convection.

[0058] As an example, the first refrigerator (210) includes a compressor (211) for compressing a refrigerant, a condenser (213) through which the refrigerant compressed by the compressor (211) passes, an expansion valve (215) to which the refrigerant that has passed through the condenser (213) is supplied, and an evaporator (220) to which the refrigerant that has passed through the expansion valve (215) is supplied. The air (F) circulating in the space (101) of the chamber (100) is cooled as it passes through the evaporator (220).

[0059] Furthermore, the first temperature control unit (200) may include a first heater (230) for heating the air that has passed through the evaporator (220). The first heater (230) may be provided one or more times along the direction of airflow. The air that has been cooled in the process of passing through the evaporator (220) is heated in the process of passing through the first heater (230) and then supplied to the space (101).

[0060] Furthermore, the first temperature control unit (200) may include a fan (240) for circulating air whose temperature has been controlled through the first refrigerator (210) and the first heater (230) into the space (101). The fan (240) allows air that has passed sequentially through the evaporator (220) and the first heater (230) to be supplied to the space (101) in the chamber (100), and the air discharged from the space (101) to pass sequentially through the evaporator (220) and the first heater (230) again to control the temperature.

[0061] Figures 5 to 7 are schematic diagrams showing one embodiment of the second temperature control unit that constitutes the cycle test apparatus.

[0062] Referring to Figure 3, the cycle test apparatus (1) includes a second temperature control unit (300) provided to cool one or more partition walls (for example, the upper wall 113) among the multiple partition walls (110:111~114) that form the space (101).

[0063] The second temperature control unit (300) can be configured to directly cool the partition wall (e.g., the upper wall 113) by contacting the partition wall (e.g., the upper wall 113). The second temperature control unit (300) can be configured to regulate the temperature of the space (101) by a conduction method that directly cools the partition wall.

[0064] Furthermore, the second temperature control unit (300) may include a second heater (not shown) for raising the temperature of any one of the partition walls. In this way, the second temperature control unit (300) can be configured to directly cool or raise the temperature of one or more partition walls.

[0065] In particular, the second temperature control unit (300) is provided to directly cool or raise the temperature of the partition wall of the chamber (100) by conduction in order to accelerate the heat flux of the partition wall of the chamber (100) when the test temperature conditions of the space (101) change.

[0066] Referring to Figures 1 and 4, the cycle test apparatus (1) may include a housing (10) that forms the exterior of the apparatus. One or more chambers (100) are arranged inside the housing (10). Multiple chambers (100) may be provided inside the housing (10) and may have a structure that is open to one side of the housing (10). A door (40) may be provided in the housing (10) so that the open side of the chamber (100) can be sealed. Figure 1 shows a configuration in which two chambers (100, 100') are arranged above and below, with the lower chamber (100') shown closed by the door (40) and the upper chamber (100) shown without the door.

[0067] The chamber (100) may have an approximately rectangular parallelepiped shape and one side may be open.

[0068] The plurality of partition walls (110) include a pair of opposing side walls (111, 112), and the plurality of partition walls (110) may also include a rear wall (115, see Figure 5) connecting the pair of side walls (111, 112). The rear wall (115) corresponds to the surface of the chamber (100) that faces the open surface (or door). In this case, a plurality of flow holes can be formed in either one of the side walls (111, 112) or the rear wall (115), and air that has passed through the evaporator (220) and fan (240) can flow into the space (101) through the flow holes.

[0069] For example, multiple flow holes (111a, 112a) can be formed in each side wall (111, 112). In this case, the air (F) that has passed through the evaporator (220) and fan (240) flows into the space (101) through the flow hole (111a) in one of the side walls (111), and the air in the space (101) is discharged to the outside of the space (101) through the other side wall (112), and then passes through the evaporator (220) and the first heater (230) in sequence to regulate the temperature. With such a structure, a horizontal airflow can be formed in the chamber (100).

[0070] Furthermore, when the door (40) is closed, the space (101) can be sealed by the multiple partition walls (110) and the door (40), and air can flow inside and outside the space (101) through the multiple flow holes (111a, 112a) formed in each of the side walls (111, 112).

[0071] In contrast, the multiple partition walls (110) may include an upper wall (113) and a lower wall (114) connecting a pair of side walls, and multiple flow holes may be formed in the upper wall (113) and the lower wall (114), allowing air that has passed through the evaporator (220) and the fan (240) to flow into the space (101) through the flow holes in the upper wall (113) and the lower wall (114). With such a structure, a vertical airflow can be formed within the chamber (100).

[0072] Furthermore, the second temperature control unit (300) can be provided in any one of the partition walls (110). For example, the second temperature control unit (300) can be provided in one of the upper walls (113) and lower walls (114) that connect a pair of side walls among the multiple partition walls. Also, the second temperature control unit (300) can be arranged to surround a predetermined area or more of the partition wall (upper wall or lower wall).

[0073] The housing (10) may also include a first case (20) surrounding a plurality of partition walls (110) of the chamber (100) and a second case (30) partitioned from the first case (20). The chamber (100) is placed inside the first case (20). The partition walls (110) that form the space (101) of the chamber (100) can be placed at a predetermined distance from the inner surface of the first case (20), thereby creating an airflowable space (S1) between the partition walls (110) and the first case (20). The second case (30) is mounted on the first case (20), and they can be arranged such that the first case (20) is located in front of the device (1) and the second case (30) is located behind the device (1).

[0074] As an example, an evaporator (220) and a fan (240) can be placed in the space (S1) between the first case (20) and the partition wall (110). The first case (20) may include a first member (21) that surrounds a pair of side walls of the test chamber (100) and a second member (25) that surrounds a partition wall (rear wall) that is separated from the first member (21) and forms the rear surface of the space (101).

[0075] The first member (21) and the second member (25) can be partitioned so that they each have separate spaces, and the first member (21) and the second member (25) can be connected in a way that allows air to flow through them.

[0076] An evaporator (220), a first heater (230), and a fan (240) can be arranged in the internal space (S2) of the second member (25). Inside the second member (25), the evaporator (220) can be placed upstream along the direction of airflow, and the first heater (230) can be placed downstream in sequence.

[0077] In other words, the space (S1) between the first member (21) and the side walls (111, 112) of the chamber and the internal space (S2) of the second member (25) can be connected in a way that allows fluid movement.

[0078] Referring to Figures 3 and 4, the air (F) discharged from the space (101) flows into the internal space (S2) of the second member (25) through the space (S1) between the first member (21) and the side wall (112) of the chamber, passes sequentially through the evaporator (220) and the first heater (230) located inside the second member (25), then flows into the space (S1) between the first member (21) and the side wall (112) of the chamber, and can then be supplied to the space (101).

[0079] Referring to Figure 4, the compressor (211) and condenser (213) can be placed in the second case (30), and the expansion valve (215) can also be placed in the second case (30).

[0080] Furthermore, the exhaust port (50, see Figure 1) connected to the second case (30) is exposed to the outside of the housing (10) and can be provided to exhaust air to the top of the device (1). Through the exhaust port (50), the high-temperature air inside the second case (30) (S) can be discharged to the outside of the device (1).

[0081] Referring to Figure 5, the second temperature control unit (300) may include a cooling channel section (330) located in the partition wall (upper wall or lower wall) and a heat transfer medium flowing through the cooling channel section (330). For example, the heat transfer medium may include a refrigerant, cooling water, antifreeze, thermal oil, or air.

[0082] Furthermore, the cooling channel section (330) can be arranged to surround a predetermined area or more of the partition wall (upper wall or lower wall), for example, it can be arranged in a zigzag pattern to surround a predetermined area or more of the partition wall (upper wall or lower wall).

[0083] The cooling channel section (330) can be configured as a piping system through which a heat transfer medium flows. When the cooling channel section (330) is configured as a piping system, the cooling pipes can be arranged to be in contact with a partition wall (upper wall or lower wall).

[0084] Furthermore, the cooling channel section (330) can be connected to a second refrigerator (350) for adjusting the temperature of the heat transfer medium. For example, the second refrigerator may include a compressor for compressing the heat transfer medium, a condenser, an expansion valve, and an evaporator.

[0085] Furthermore, the heat transfer medium may be chilled water or cooling water supplied from a utility within the factory facility where the cycle test device (1) is installed.

[0086] Referring to Figure 6, the partition wall (for example, the upper wall 113) may include an inner wall (116) surrounding the space (101) and an outer wall (117) surrounding the inner wall (116). That is, either the upper wall (113) or the lower wall (114) may have a double-wall structure. For example, if the upper wall (113) has a double-wall structure, the cooling channel section (330) can be formed in the space (R) between the inner wall (116) and the outer wall (117). In this way, the space (R) between the double-wall structure can be used as the cooling channel section (330) without installing separate piping.

[0087] Referring to Figure 7, the second temperature control unit (300) may include a thermoelectric element (Peltier element, 310). The thermoelectric element (310) may consist of one or more units. The thermoelectric element (310) may be arranged to surround a predetermined area or more of the partition wall (upper wall or lower wall). The thermoelectric element (310) may also be connected to a drive circuit unit (315) for driving the thermoelectric element (310). The thermoelectric element (310) may include a heat-absorbing part and a heat-generating part, and the heat-absorbing part may be in contact with the partition wall to directly cool the partition wall.

[0088] Referring to Figure 2, the cycle test apparatus (1) may include one or more temperature sensors (500) for measuring the temperature inside the space (101).

[0089] The cycle test apparatus (1) may include a plurality of temperature sensors (500), and the plurality of temperature sensors (500) may be arranged to measure the temperature of different regions of the space (101).

[0090] Furthermore, the cycle test apparatus (1) may include a control unit (400) that, based on temperature information within the space (101), drives a first temperature control unit (200) when the space (101) is operating at a constant temperature, and drives a second temperature control unit (300) when the temperature of the space (101) changes.

[0091] For example, the control unit (400) can be configured to drive the first temperature control unit (200) when the space (101) is operating at a constant temperature, and to drive the second temperature control unit (300) when it is operating in a cooling operation, based on the temperature information within the space (101).

[0092] Furthermore, the control unit (400) may be configured to operate the first chiller (210), the first heater (230), and the fan (240) during constant temperature operation. That is, the control unit (400) may drive the first temperature control unit (200) and not operate the second temperature control unit (300) during constant temperature operation. In this document, constant temperature operation means operation that maintains the temperature of the space (101) at a set temperature, and may also include operation within the set temperature range.

[0093] On the other hand, depending on fluctuations in the heat load or test temperature within the space (101), a cooling operation can be performed to lower the temperature to a set temperature.

[0094] The control unit (400) is configured to operate the first chiller (210) and the second temperature control unit (300) respectively during cooling operation. That is, during cooling operation, the control unit (400) can drive the first temperature control unit (200) in the same way as during constant temperature operation, and simultaneously operate the second temperature control unit (300).

[0095] On the other hand, the control unit (400) can operate the second temperature control unit (300) and the fan (240) respectively during cooling operation. Specifically, the control unit (400) can be configured to perform cooling operation by eliminating the temperature control function through the first chiller (210) and operating only the second temperature control unit (300) and the fan (240).

[0096] Figure 8 is a schematic diagram showing a cycle test apparatus (1000) related to another embodiment of the present invention.

[0097] Referring to Figure 8, a cycle test apparatus (1000) related to another embodiment of the present invention includes a chamber (1100) having a plurality of spaces (101) for housing a battery (B), and having a plurality of partitions (110) forming each space (101).

[0098] Furthermore, the cycle test apparatus (1000) includes a first temperature control unit (200) which includes a first refrigerator (210) provided to supply air to each space (101) and adjust the temperature of the supplied air, and a plurality of second temperature control units (300) provided to cool one or more partition walls (110) of each space (101).

[0099] In this embodiment, the first temperature control unit (200) is used in common for multiple spaces (101), and the second temperature control unit (300) can be applied individually to each space (101).

[0100] Furthermore, the cycle test apparatus (1000) may include a plurality of temperature sensors (500) for measuring the temperature within each space (101), and a control unit (400) provided to individually control a plurality of second temperature control units (300) based on the temperature information within each space (101).

[0101] The control unit (400) can be configured to drive a first temperature control unit (200) during constant temperature operation and a second temperature control unit (300) during temperature changes for each space (101). For example, the control unit (400) can be configured to drive a first temperature control unit (200) during constant temperature operation and a second temperature control unit (300) during cooling operation for each space (101).

[0102] Furthermore, the control unit (400) can be configured to operate the first and second temperature control units (200, 300) simultaneously during cooling operation.

[0103] According to this embodiment, if the heat load fluctuations differ for each space, cooling operations can be performed for each space (101) by individually controlling the second temperature control unit (300) provided in each space (101).
