[0035] The technical solutions of the present application will be described in detail below in combination with the drawings, obviously, the following described embodiments are part of the embodiments of the present application, not all the embodiments.

[0036] The following will be described with reference to Figures 1 to 7 The battery capable of identifying battery cell failure and the electric two-wheeled vehicle according to the embodiments of the present application are described.

[0037] The battery capable of identifying battery cell failure provided by the embodiments of the present application comprises a shell body and a battery cell module arranged in the shell body.

[0038] The battery cell module comprises a module shell 100 and a plurality of battery cells 200, the module shell 100 is detachably provided with at least one side plate, and the plurality of battery cells 200 are arranged in the shell along a first direction.

[0039] The detection module 1101 is used for detecting the running state of the plurality of battery cells 200.

[0040] The control module 1102 is electrically connected with the detection module 1101.

[0041] The communication module 1103 is connected with the control module 1102.

[0042] In the embodiment of the application, by arranging a plurality of battery cells 200 in the module shell 100 with the side plates being detachable, the faulty battery cell 200 can be quickly removed after the detection module 1101 and the control module 1102 detect the fault, thereby effectively reducing the time and manpower required for troubleshooting and dismounting the battery cell 200.

[0043] The module shell 100 is arranged in the manner that at least one side plate is detachable, which facilitates the extraction of the battery cell 200 in the electrical module without the need to dismount the protective plate 500 at the top of the module shell 100 and the wiring terminal 204 and other components.

[0044] The detection module 1101 can be used to detect the operating state of each battery cell 200 and feed back the detected data to the control module 1102.

[0045] After obtaining the operating state of the detection module 1101, the control module 1102 can confirm the fault of the battery cell 200. For example, after obtaining the voltage data, it can be determined whether there is a voltage problem with the battery cell 200, and after obtaining the temperature data, it can be determined whether there is an overheating problem with the battery cell 200. Overvoltage, undervoltage, and overheating of the battery cell 200 all indicate that the battery is faulty.

[0046] Specifically, for overvoltage, a high voltage threshold can be directly set, and the control module 1102 can compare the detected voltage with the high voltage threshold after obtaining the voltage collected by the detection module 1101 to directly determine whether overvoltage occurs. For undervoltage, a low voltage threshold can be directly set, and the control module 1102 can compare the detected voltage with the low voltage threshold after obtaining the voltage collected by the detection module 1101 to directly determine whether undervoltage occurs. For overheating of the battery cell 200, a high battery temperature threshold can be directly set, and the control module 1102 can compare the detected battery temperature with the high battery temperature threshold after obtaining the battery temperature based on the collection result of the detection module 1101 to directly determine whether overvoltage occurs.

[0047] The core control device of the control module 1102 can be a DSP, a single-chip microcomputer, or an ARM, and can specifically be a SYM32 series. The specific model of the core control device of the control module 1102 is not limited in the embodiment of the application, and an engineer can select the model according to actual needs.

[0048] The communication module 1103 can be a wired communication module 1103, such as RS, RS, CAN, and the like.

[0049] The communication module 1103 can realize the communication connection between the control module 1102 and the control system of the electric two-wheeler. After confirming the fault, the control module 1102 can transmit the fault information to the control system of the electric two-wheeler through the communication module 1103 to prompt the user of the two-wheeler to troubleshoot in time.

[0050] In some embodiments, the detection module 1101 includes a plurality of voltage detection units, each of which is electrically connected to the control module 1102. The plurality of voltage detection units are arranged corresponding to the plurality of battery cells 200, and each voltage detection unit is used to detect the voltage of the corresponding battery cell 200.

[0051] In this embodiment, a corresponding voltage detection unit is arranged for each battery cell 200, and the one-to-one detection of the voltage of each battery cell 200 can be realized by using the corresponding voltage detection unit, thereby facilitating the control module 1102 to determine whether each battery cell 200 has a voltage problem and whether the battery cell 200 has a fault.

[0052] The voltage detection unit can directly use a resistance voltage dividing circuit to divide the voltage of each battery cell 200 collected by the resistance voltage dividing circuit, and then transmit the voltage to the control module 1102 after being processed by a signal conditioning circuit.

[0053] The signal conditioning circuit can include an operational amplifier circuit and a signal isolation circuit to process the signal after voltage division, and can also isolate the control module 1102 from the battery cell 200 part.

[0054] In some embodiments, the detection module 1101 includes a plurality of temperature detection units, each of which is electrically connected to the control module 1102. The plurality of temperature detection units are used to detect the temperature of the plurality of battery cells 200.

[0055] In this embodiment, a corresponding temperature detection unit is arranged for each battery cell 200, and the one-to-one detection of the temperature of each battery cell 200 can be realized by using the corresponding temperature detection unit, thereby facilitating the control module 1102 to determine whether each battery cell 200 has a temperature problem and whether the battery cell 200 has a fault.

[0056] The temperature detection unit can convert the temperature into a corresponding voltage, and then transmit the voltage to the control module 1102 after being processed by a signal conditioning circuit.

[0057] The signal conditioning circuit can include an operational amplifier circuit and a signal isolation circuit to process the signal after voltage division, and can also isolate the control module 1102 from the battery cell 200 part.

[0058] In some embodiments, the control module 1102 can be connected to the detection module 1101 through a communication interface.Figure 6 and Figure 7 The plurality of battery cells 200 are arranged in sequence, and an ear assembly is arranged between two adjacent battery cells 200. The ear assembly includes two first ears 201 that are attached to each other, and the two first ears 201 are respectively connected to the two adjacent battery cells 200. The battery cell module further includes a plurality of clamping assemblies 300. Each clamping assembly 300 includes two clamping pieces 301 that are attached to the two first ears 201 of the ear assembly on opposite sides, and a third fastener 302 is arranged between the two clamping pieces 301. The temperature detection unit is arranged on the clamping assembly 300.

[0059] The plurality of battery cells 200 are arranged in sequence, and an ear assembly is arranged between two adjacent battery cells 200. The ear assembly includes two first ears 201 that are attached to each other, and the two first ears 201 are respectively connected to the two adjacent battery cells 200. The battery cell module further includes a plurality of clamping assemblies 300. Each clamping assembly 300 includes two clamping pieces 301 that are attached to the two first ears 201 of the ear assembly on opposite sides, and a third fastener 302 is arranged between the two clamping pieces 301. The temperature detection unit is arranged on the clamping assembly 300.

[0060] The plurality of battery cells 200 are arranged in sequence, and an ear assembly is arranged between two adjacent battery cells 200. The ear assembly includes two first ears 201 that are attached to each other, and the two first ears 201 are respectively connected to the two adjacent battery cells 200. The battery cell module further includes a plurality of clamping assemblies 300. Each clamping assembly 300 includes two clamping pieces 301 that are attached to the two first ears 201 of the ear assembly on opposite sides, and a third fastener 302 is arranged between the two clamping pieces 301. The temperature detection unit is arranged on the clamping assembly 300.

[0061] Specifically, the clamping assembly 300 is used to connect two adjacent battery cells 200. If the temperature of any one of the two battery cells 200 connected by the clamping assembly 300 is too high, the temperature of the clamping assembly 300 will increase. By using this feature, the problematic battery cell 200 can be quickly locked to two, and subsequent manual detection of the two battery cells 200 can be directly performed. In addition, in some embodiments, the temperature of the two clamping assemblies 300 connected by the two ears of each battery cell 200 can be used to determine whether the battery cell 200 has a problem. Specifically, if only one of the clamping assemblies 300 connected by one ear of the battery cell 200 (except for the outermost battery cell 200) has a temperature anomaly, it indicates that the battery cell 200 does not have a temperature anomaly. When both clamping assemblies 300 connected by the two ears have a temperature anomaly, it indicates that the battery cell 200 has a temperature anomaly. For the outermost battery cell 200, when an anomaly occurs, only one of the two ears of the battery cell 200 connected to the outermost battery cell 200 will have a temperature increase. By using this point, the temperature anomaly can also be determined.

[0062] The middle cell 200 in the plurality of cells 200 can be provided with two first tabs 201, and the two outermost cells 200 can be provided with one first tab 201. The middle cell 200 is attached to the corresponding first tabs 201 of the two adjacent cells 200 through the two first tabs 201 thereon, and the outermost cell 200 is attached to the corresponding first tab 201 of the adjacent cell 200 through the one first tab 201 thereon. The third fastener 302 is installed between the two clamping pieces 301, which can be a core-pulling rivet. The core-pulling rivet is stable in connection and easy to install. Of course, the third fastener 302 can also be of other structures, such as a bolt, which will not be described here.

[0063] In this embodiment, when the two adjacent cells 200 of the cell module need to be connected in series, the two first tabs 201 of the tab assembly are attached, and then the two clamping pieces 301 of the clamping assembly 300 are attached to the sides of the two first tabs 201 of the tab assembly, respectively, and the two clamping pieces 301 are connected by the third fastener 302. The two clamping pieces 301 can clamp the two first tabs 201 of the tab assembly, so that the two first tabs 201 of the tab assembly are kept in a conductive state of mutual attachment. In this way, the connection of the first tab 201 is more convenient, time-saving and labor-saving, and more firm, and there is no risk of the welding slag piercing the aluminum plastic film, and the quality of the battery is better. In addition, since the two first tabs 201 are clamped by the clamping assembly 300, they can be quickly disassembled, and when a faulty cell 200 needs to be disassembled, the operation is more convenient and time-saving and labor-saving.

In this way, the clamping piece 301 is more convenient and stable to clamp.

[0078] In some embodiments, referring to Figures 2 to 4 , the battery cell module further comprises a heat preservation box 700, the heat preservation box 700 is sleeved on the outside of the module shell 100 and located in the outer shell.

[0079] In the embodiment, the heat preservation box 700 is provided, and when the cold weather comes, the module shell 100 with the battery cell 200 can be placed in the heat preservation box 700, the heat preservation box 700 can preserve the battery cell 200, so as to avoid the poor charging and discharging performance of the battery at low temperature, and to avoid the serious shortage of the endurance of the electric two-wheeled vehicle in cold weather.

[0080] In some embodiments, referring to Figure 3 , the heat preservation box 700 comprises:

[0081] a heat preservation bottom wall 701;

[0082] four heat preservation side walls 702, respectively reversibly connected to four sides of the heat preservation bottom wall 701;

[0083] a plurality of adhesive strips 703, the adhesive strips 703 are arranged on one of the two adjacent heat preservation side walls 702 and are detachably attached to the other, so as to realize the connection of the two adjacent heat preservation side walls 702.

When the module shell 100 with the battery cell 200 needs to be taken out of the heat preservation box 700, the adhesive tape 703 is separated from the adjacent heat preservation side wall 702, and then the four heat preservation side walls 702 are flipped downwards to be separated from the four sides of the module shell 100, so that the module shell 100 with the battery cell 200 can be taken out.
