DETAILED DESCRIPTION

[0022] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. In addition, the present invention uses terms such as "first" and "second" to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0024] like Figures 1 to 5 As shown, and refer to Figure 2 As shown in FIG, a battery health analysis device according to an embodiment of the present invention includes a support frame 110 , a heat sink 130 , a collection module 210 , a monitoring terminal 260 and a master station device 270 .

[0025] There are multiple support frames 110, and the multiple support frames 110 are rotated and connected in sequence from left to right. The left rear side of each support frame 110 has a first connecting surface, and the right rear side of each support frame 110 has a second connecting surface. The first connecting surface and the second connecting surface are detachably connected.

[0026] The support frames 110 have a first state and a second state. The leftmost support frame 110 is the head end support frame 110, and the rightmost support frame 110 is the tail end support frame 110. In the first state, the first connecting surface and the second connecting surface are separated, allowing the multiple support frames 110 to be deployed. In the second state, the first connecting surface is connected to the adjacent second connecting surface, and the first connecting surface of the head end support frame 110 is connected to the second connecting surface of the tail end support frame 110, so that the multiple support frames 110 are connected to form a ring structure.

[0027] Preferably, four support frames 110 are provided. When the support frames 110 are in the second state, the four support frames 110 are connected to form a square ring structure.

[0028] Specifically, the plurality of support frames 110 are detachably mounted on the outer wall of the battery pack 300 by means of magnetic connection, snap connection, or threaded connection, and can also be directly placed on the ground or on top of the battery pack 300 .

[0029] One or more collection modules 210 are provided, and the collection modules 210 are used to be electrically connected to the battery pack 300. The collection modules 210 can be detachably installed on the support frame 110. Multiple collection modules 210 are arranged in a one-to-one correspondence with multiple support frames 110, and multiple collection modules 210 are connected in series through a first connecting line 240.

[0030] It should be noted that the acquisition module 210 is used to detect and collect relevant parameters from the battery cells in the battery pack 300. Each battery cell can be a single battery or a group of batteries. Multiple acquisition modules 210 can simultaneously detect and collect data from multiple battery cells. Each acquisition module 210 is detachably connected to the support frame 110, accommodating different numbers and models of battery packs 300, thereby improving the versatility of the device and expanding its application range.

[0031] There are multiple heat sinks 130 , which are fixedly mounted on the support frame 110 . The heat sinks 130 are used to dissipate heat from the acquisition module 210 , which is beneficial for ensuring long-term stable operation of the equipment. Multiple heat sinks 130 are arranged in a one-to-one correspondence with multiple support frames 110 .

[0032] The monitoring terminal 260 is connected to one of the acquisition modules 210 via the second connection line 250. The relevant parameters collected by each acquisition module 210 are transmitted to the monitoring terminal 260 via the second connection line 250. The monitoring terminal 260 analyzes and calculates the relevant parameters to obtain the health status of the battery pack 300.

[0033] The master station 270 is connected to the monitoring terminal 260. The monitoring terminal 260 transmits the relevant parameters and health results received to the master station 270 via signals, where they are stored and displayed, thereby completing the health analysis of the battery pack 300.

[0034] In this way, when it is necessary to detect and analyze the health of the battery pack 300, the multiple support frames 110 are unfolded into a plane. The unfolded state of the battery health analysis equipment can be flexibly adapted to battery packs 300 of different layouts, solving the problem that traditional fixed cabinets are fixed in shape and difficult to enter a small space; before detecting and analyzing the health of the battery pack 300, or after the health analysis of the battery pack 300 is completed, the multiple support frames 110 are folded and connected to form a ring structure. The folded state of the battery health analysis equipment can greatly reduce the occupied space, facilitate storage, and facilitate staff to carry when working at high altitudes or to transport in a narrow space; in addition, each acquisition module 210 is detachably connected to the support frame 110, which is convenient for carrying or replacing modules separately, and is also convenient for quick assembly as needed at the work site, reducing the overall carrying burden of the equipment, and can quickly and flexibly complete the health analysis work.

[0035] In some embodiments of the present application, Figure 2 As shown, each first connecting surface is inclined to the right from front to back, and each second connecting surface is inclined to the left from front to back. Each first connecting surface is provided with a first magnetic sheet 111, and each second connecting surface is provided with a second magnetic sheet 112. The magnetic poles of the first magnetic sheet 111 and the second magnetic sheet 112 are opposite. The first connecting surface and the second connecting surface are arranged at an angle, so that the two adjacent support frames 110 can be attached in a more compact manner after folding, further reducing the storage volume and improving portability. The oppositely charged property of the first magnetic sheet 111 and the second magnetic sheet 112 allows the two adjacent support frames 110 to be quickly fixed when folded, improving storage efficiency.

[0036] It should be noted that when multiple support frames 110 are installed on the outer wall of the battery pack 300 , the front refers to the side of the support frame 110 facing the battery pack 300 , and the rear refers to the side of the support frame 110 facing away from the battery pack 300 .

[0037] In some embodiments of the present application, Figure 2 As shown, the left side of the first end support frame 110 or the right side of the end support frame 110 is rotatably connected to a handle 113. The setting of the handle 113 is convenient for the staff to easily hold and lift the multiple support frames 110 with one hand through the handle 113 after folding the multiple support frames 110.

[0038] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the heat sink 130 includes a connecting frame 131 and a fan 132 . The connecting frame 131 is cross-shaped and fixed in the supporting frame 110 . The fan 132 is mounted on the connecting frame 131 .

[0039] Each support frame 110 is equipped with a protective screen 120. A fan 132 is positioned between the connecting frame 131 and the protective screen 120. The acquisition module 210 is mounted on the side of the protective screen 120 facing away from the fan 132. The protective screen 120 prevents tools, cables, and other items from accidentally becoming entangled in the fan 132, ensuring safe operation of the equipment.

[0040] In some embodiments of the present application, Figures 2 to 4 As shown, each support frame 110 is provided with a clamp 150 for mounting the acquisition module 210 , and each clamp 150 includes two moving rods 151 and two springs 153 .

[0041] A sleeve 140 is fixed on the upper and lower sides of each support frame 110, and each sleeve 140 extends up and down. One end of each moving rod 151 slides into the sleeve 140 and is fixed with a baffle 152. The other end of each moving rod 151 is fixed with a splint 154, and the two ends of each spring 153 are respectively fixed to the baffle 152 and the sleeve 140.

[0042] In this way, the staff only needs to pull the clamping plates 154 to overcome the elastic force of the spring 153, clamp the acquisition module 210 between the two clamping plates 154, and then release the clamping plates 154 to quickly and conveniently complete the installation of the acquisition module 210.

[0043] In some embodiments of the present application, Figure 4 As shown, each clamping plate 154 has a curved surface on the side away from the support frame 110. The curved surface of the clamping plate 154 located on the upper side slopes downward from close to the support frame 110 to away from the support frame 110, while the curved surface of the clamping plate 154 located on the lower side slopes upward from close to the support frame 110 to away from the support frame 110. The curved surface of each clamping plate 154 forms a blocking surface on the outside of the clamping plate 154 to prevent the collection module 210 from sliding and falling due to external forces, thereby ensuring the stable clamping of the collection module 210 by the clamp 150.

[0044] In some embodiments of the present application, Figure 1 and Figure 5 As shown, each acquisition module 210 is provided with a detection connection member 220 , and each detection connection member 220 includes a positive electrode connection line 221 and a negative electrode connection line 222 .

[0045] One end of each positive connection line 221 is electrically connected to the acquisition module 210 , and the other end of each positive connection line 221 is provided with a positive connector 223 . Each positive connector 223 is used to mate with a positive plug of the battery pack 300 .

[0046] One end of each negative connection line 222 is electrically connected to the acquisition module 210 , and the other end of each negative connection line 222 is provided with a negative connector 224 . Each negative connector 224 is used to mate with a negative plug of the battery pack 300 .

[0047] In this way, each acquisition module 210 corresponds to an independent detection connector 220, allowing for targeted wiring of multiple battery cells. When testing different numbers of battery packs 300, the detection connector 220 corresponding to the acquisition module 210 can be flexibly selected. Furthermore, when wiring, workers only need to align the connector head with the plug to complete the electrical connection, shortening wiring time and improving work efficiency.

[0048] In some embodiments of the present application, Figure 1 and Figure 5 As shown, each acquisition module 210 includes a first circuit board, an internal resistance detection unit, a voltage detection unit, a current detection unit and a temperature detection unit, and the internal resistance detection unit, the voltage detection unit, the current detection unit and the temperature detection unit are all integrated on the first circuit board.

[0049] The internal resistance detection unit is used to detect the internal resistance of the battery pack 300 and transmit the detected internal resistance parameters to the monitoring terminal 260. The internal resistance detection unit includes a signal generation subunit and a signal acquisition subunit. The signal generation subunit is used to inject an AC signal of a specific frequency into the battery pack 300, and the signal acquisition subunit is used to collect the voltage and current responses of the battery pack 300 to the AC signal to obtain the internal resistance detection value.

[0050] The voltage detection unit is used to detect the voltage of the battery pack 300 and transmit the detected voltage parameters to the monitoring terminal 260 .

[0051] The current detection unit is used to detect the current of the battery pack 300 and transmit the detected current parameters to the monitoring terminal 260 .

[0052] The temperature detection unit is used to detect the temperature of the battery pack 300 and transmit the detected temperature parameters to the monitoring terminal 260. The positive and negative plugs of the battery pack 300 are both equipped with thermistors. The resistance of the thermistors changes with the temperature of the battery pack 300. The temperature detection unit obtains the detected temperature value of the battery pack 300 based on the change in the thermistor resistance.

[0053] By setting up the internal resistance detection unit, voltage detection unit, current detection unit and temperature detection unit, the internal resistance, voltage, current and temperature of the battery pack 300 can be detected, which can fully reflect the health status of the battery pack 300 and avoid the inability of a single detection parameter to accurately evaluate the true status of the battery.

[0054] In some embodiments of the present application, Figure 1 and Figure 5 As shown, the monitoring terminal 260 includes a second circuit board, a processing module, an input module, an output module and an encryption module, and the processing module, the input module, the output module and the encryption module are all integrated on the second circuit board.

[0055] The processing module has a built-in temperature compensation algorithm and SOC calibration algorithm, which are used to analyze and calculate the internal resistance parameters, voltage parameters, current parameters and temperature parameters transmitted by the acquisition module 210 to obtain the battery health.

[0056] The input module is used to input operation instructions and parameter information of the battery pack 300, such as rated capacity, number of batteries, installation date, etc.

[0057] The output module is connected to the master station device 270 by signal, and is used to transmit the internal resistance parameters, voltage parameters, current parameters, temperature parameters and health results to the master station device 270 for storage and display on the master station device 270.

[0058] The encryption module is used to encrypt the data transmitted between the output module and the master station device 270.

[0059] Specifically, the processing module uses the STM32 series microcontroller, which has the characteristics of high performance and low power consumption, and can complete data processing and analysis quickly and accurately.

[0060] Specifically, the output module is a 6G output module.

[0061] In some embodiments of the present application, the input module is a touch screen.

[0062] The working process of the present invention is: The first step is installation. Multiple support frames 110 are unfolded into a plane shape, and multiple support frames 110 are installed on the outer wall of the battery pack 300. Multiple collection modules 210 are respectively installed on the multiple support frames 110, and the detection connector 220 of each collection module 210 is plugged into the battery pack 300.

[0063] The second step is detection. Operational instructions and battery pack 300 parameter information are input through the touch screen. The signal generation subunit injects an AC signal of a specific frequency into the battery pack 300. The signal acquisition subunit collects the voltage and current responses of the battery pack 300 to the AC signal. Simultaneously, the voltage detection unit, current detection unit, and temperature detection unit detect the voltage, current, and temperature parameters of the battery pack 300, respectively, and transmit the detected parameters to the processing module. The processing module, combined with a temperature compensation algorithm and an SOC calibration algorithm, analyzes and calculates the internal resistance parameters, voltage parameters, current parameters, and temperature parameters to obtain the battery health status. The output module and encryption module then transmit the data to the master station 270 for storage and display.

[0064] The third step is storage. After the detection is completed, the detection connector 220 of each collection module 210 is disconnected from the battery pack 300, and the collection module 210 is removed from the support frame 110. The multiple support frames 110 are removed from the outer wall of the battery pack 300, and the multiple support frames 110 are folded and connected to form a ring structure.

[0065] In summary, an embodiment of the present invention provides a battery health analysis device that can comprehensively collect the internal resistance, voltage, current, and temperature parameters of the battery pack 300. Combined with the analysis and calculation of the processing module, the accuracy of the battery health analysis is improved. At the same time, the collection module 210 is organized using the support frame 110, which can be easily stored and carried, thereby improving the flexibility, compactness, and rationality of the device.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
