Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In a first aspect of the present invention, a battery system for a vehicle is provided.
Fig. 1 to 3 schematically show a battery system 100 according to a preferred embodiment of the present invention. Fig. 1 is an exploded perspective view of a battery system 100 according to a preferred embodiment of the present invention; fig. 2 is a partially assembled schematic view of the battery system 100 shown in fig. 1, showing the detection device 130 mounted on the housing 110 and inserted into the exhaust channel 191; and fig. 3 is a perspective view of the detection device 130 shown in fig. 1. The battery system 100 of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the battery system 100 includes a case 110, a battery module 120, an exhaust port 192, a detection device 130, and a control device (not shown).
As shown in fig. 1, the case 110 has an inner cavity (not shown) that may form an accommodation space to accommodate components such as the battery module 120 of the battery system 100. Specifically, in the present embodiment, the housing 110 has a substantially box-like shape. The housing 110 includes a bottom wall (not shown) and a sidewall 112 extending upward from a peripheral edge of the bottom wall. The bottom and side walls 112 enclose an internal cavity having an open top. In addition, the housing 110 also includes a top wall 113 covering the top opening of the internal cavity. The bottom wall and the side wall 112 may be integrally formed, and the top wall 113 may be detachably coupled to the side wall 112 so as to dispose the battery module 120 and the like of the battery system 100 in the inner cavity. Of course, in other embodiments of the invention not shown, the housing 110 may also be any other suitable shape. The housing 110 is typically made of a rigid material.
As shown in fig. 1, at least one battery module 120 is disposed in the inner cavity of the case 110. In the present embodiment, one battery module 120 is disposed in the inner cavity of the housing 110. However, in other embodiments not shown in the present disclosure, any other suitable number of battery modules 120, such as two, three or more, may be disposed in the inner cavity of the housing 110. When the plurality of battery modules 120 are disposed in the inner cavity of the case 110, the plurality of battery modules 120 are connected in series to be able to provide sufficient battery power to the vehicle. Each battery module 120 includes at least one battery cell 121. Preferably, the battery module 120 may include a plurality of battery cells 121, and the plurality of battery cells 121 are connected together in series to be able to provide sufficient battery energy to the vehicle.
As shown in fig. 2, the battery system 100 includes a gas exhaust port 192, and the gas exhaust port 192 is configured to exhaust gas generated in the battery module 120. The exhaust port 192 may be provided in a variety of arrangements.
In the present embodiment, as shown in fig. 1, the battery system 100 includes a battery module cover 190 covering the battery module 120. The battery module cover 190 is disposed between the battery module 120 and the top wall 113 of the case 110. The battery module cover 190 may be, for example, a battery wiring board on which the printed circuit board 140 is disposed. The battery module cover 190 may be another cover additionally provided. At least a portion of the battery module cover 190 is spaced apart from the battery module 120 to form a gas exhaust channel 191 between the battery module cover 190 and the battery module 120. The exhaust passage 191 extends from one end to the other end of the housing 110. The end of the exhaust passage 191 communicates with the outside to form an exhaust port 192 at the end of the exhaust passage 191. When thermal runaway (e.g., fire) occurs in any one of the battery cells 121 in the battery module 120, a large amount of high-temperature and high-pressure gas is generated in the battery module 120. These gases are blocked by the battery module cover 190 covering the battery module 120 when being ejected from the battery module 120 to flow along the exhaust passage 191 between the battery module cover 190 and the battery module 120, and are discharged from the exhaust port 192 at the end of the exhaust passage 191.
Specifically, in the present embodiment, as shown in fig. 1, at least one of the battery module cover 190 and the battery module 120 is provided with a recess that is recessed toward a direction away from the other to form a gas discharge passage 191 between the battery module cover 190 and the battery module 120, and an end of the gas discharge passage 191 forms a gas discharge port 192. For example, the battery module cover 190 covers the battery modules 120 above the battery modules 120, and a concave portion recessed toward the upper side is provided in the battery module cover 190 to form the air discharge passage 191 between the battery module cover 190 and the battery modules 120.
As shown in fig. 2 and 3, the detection device 130 is disposed at the air outlet 192. The detection device 130 includes a support 134 and a detection circuit 132. The support 134 is detachably mounted to the housing 110. The detection circuit 132 is disposed on the support 134. The detection circuit 132 may be disposed on the support 134 by electronic printing. The detection circuit 132 may also be arranged on the support 134 by ink printing, metal printing, or the like. The detection circuit 132 has a signal output 133. The detection circuit 132 is configured to be able to be disconnected by being damaged by gas generated in the battery module 120 when thermal runaway occurs in the battery module 120 and the signal output terminal 133 of the detection circuit 132 outputs a circuit disconnection signal when the detection circuit 132 is disconnected. It should be noted that the term "damage" as used herein refers to irreversible damage or irreversible damage. When any one of the battery cells 121 in the battery module 120 is thermally runaway, a large amount of high-temperature and high-pressure gas is generated in the battery module 120. These high temperature and high pressure gases flow at a higher flow rate toward the exhaust 192. In this process, a high flow rate of high-temperature, high-pressure gas acts on the detection circuit 132 of the detection device 130 provided at the exhaust port 192 and causes the detection circuit 132 to break and open.
For example, in one embodiment of the present invention, when the temperature of the gas generated in the battery module 120 is greater than or equal to a predetermined temperature threshold, the gas can fuse the conductive wires of the detection circuit 132, thereby causing the detection circuit 132 to be damaged. For another example, in another embodiment of the present invention, when the pressure of the gas generated in the battery module 120 is greater than or equal to the predetermined pressure threshold, the gas can apply a certain force (e.g., impact force, etc.) to the wires of the detection circuit 132, so that the wires of the detection circuit 132 are broken by the external force, and the detection circuit 132 is damaged. Either of these causes the detection circuit 132 to open.
The control means are connected to the signal output 133 of the detection circuit 132. When the detection circuit 132 is broken by the gas generated in the battery module 120, the signal output terminal 133 of the detection circuit 132 transmits a circuit breaking signal to the control device. The control device is configured to send an alarm signal to a user of the vehicle (e.g., a driver or a passenger of the vehicle) upon receiving the circuit-open signal to alert the user of the vehicle to evacuate as quickly as possible to avoid danger. The alarm signal may be an audible cue signal and/or a visual cue signal.
The installation of the detecting device 130 according to a preferred embodiment of the present invention will be described in detail with reference to fig. 2 and 3.
As shown in fig. 2, the housing 110 of the battery system 100 is generally provided with at least two handling holes 114, and the at least two handling holes 114 can be grasped by a robot to handle the battery system 100. Specifically, in a preferred embodiment of the present invention, the access hole 114 is provided at the top of the sidewall 112 of the housing 110.
As shown in fig. 2 and 3, the support 134 of the detecting device 130 includes an inserting part 135 and a clamping part 137.
The insertion member 135 is configured to be insertable into the exhaust passage 191 between the battery module cover 190 and the battery module 120 via the exhaust port 192. Preferably, insert member 135 includes body portion 148 and stop portion 136. The body part 148 is inserted into the exhaust passage 191 between the battery module cover 190 and the battery module 120 through the exhaust port 192. The body portion 148 has dimensions slightly smaller than the dimensions of the exhaust channel 191 and the exhaust port 192. The blocking portion 136 is connected to the body portion 148 and protrudes relative to the body portion 148 in a direction perpendicular to the battery module cover 190. For example, in a preferred embodiment of the present invention, the exhaust passage 191 extends in a horizontal direction. The body portion 148 of the insertion member 135 is horizontally inserted into the exhaust passage 191. The blocking portion 136 is connected to the body portion 148 at one end of the body portion 148 and protrudes downward in a vertical direction with respect to the body portion 148. The stopper 136 and the body 148 may be integrally formed or may be formed separately. The blocking portion 136 may prevent the insertion member 135 from being excessively inserted into the exhaust passage 191.
The detection circuit 132 is disposed on the insertion member 135. Specifically, the detection circuit 132 may be disposed on the body portion 148 of the insertion member 135. Alternatively, the detection circuit 132 may be disposed on the body portion 148 of the insertion member 135 by electronic printing. The body portion 148 of the insert member 135 may have a flat surface to facilitate placement of the detection circuit 132 thereon. The detection circuit 132 may be disposed at any suitable location of the body portion 148 of the insert member 135 that is exposed to the exhaust passage 191.
The clamping member 137 is connected to the insertion member 135 and clamps on the wall between the operation holes 114 of the housing 110. For example, in a preferred embodiment of the present invention, the clamping member 137 is clamped to a wall of the housing 110 between two adjacent operation holes 114. The support 134 may be detachably mounted to the housing 110 by clamping on the housing 110 by a clamping member 137 to prevent undesired movement of the detection device 130. In addition, the walls between the operation holes 114 provided on the case 110 can be directly utilized without providing an additional through hole for the clamping member 137 to clamp, thereby simplifying the structure and manufacturing process of the battery system 100 and reducing the cost.
Preferably, the clamping member 137 is slidably coupled to the insertion member 135 in a direction perpendicular to the battery module cover 190. Specifically, one of the insertion member 135 and the clamping member 137 is provided with a slide groove 138 extending in a direction perpendicular to the battery module cover 190, and accordingly, the other of the insertion member 135 and the clamping member 138 is provided with a slide portion 149, the slide portion 149 being slidable in the slide groove 138.
For example, in a preferred embodiment of the present invention, the exhaust passage 191 is disposed in a horizontal direction. The insertion member 135 is provided with a slide groove 138 extending in the vertical direction. The slide groove 138 may be provided on the blocking portion 136 of the insertion member 135. The clamping member 137 is provided with a sliding portion 149. The sliding portion 149 of the holding member 137 is slidable in the slide groove 138 in the vertical direction by an external force. During assembly, the sliding portion 149 of the clamping member 137 may be slid to a suitable position of the sliding slot 138, preferably, to the top end of the sliding slot 138. The support 134 is then inserted into the exhaust passage 191 via the exhaust port 192. Finally, the sliding portion 149 of the holding member 137 is slid to a proper position in the vertical direction so that the holding member 137 can be held on the wall between the operation holes 114. The support 134 may be removed from the housing 110 in the reverse procedure. By the movement of the sliding portion 149 in the sliding groove 138 in the direction perpendicular to the battery module cover 190, it is possible to avoid interference of the clamping member 137 with the housing 110 during assembly and disassembly of the detection device 130 to hinder the insertion of the support 134 of the detection device 130 into the exhaust passage 191 or the withdrawal from the exhaust passage 191.
Optionally, the insertion part 135 of the detection device 130 is provided with a wire harness hole (not shown). The signal output 133 of the detection circuit 132 may be passed out through a harness hole to be connected to a control device. Further, a flexible caulking portion 139 may be provided in the harness hole, and the flexible caulking portion 139 is made of a flexible material (e.g., rubber, etc.). The signal output 133 of the detection circuit 132 passes out through the flexible stuff portion 139. In this way, undesired movement of the wires of the detection circuit 132 in the beam hole can be avoided.
According to the scheme of the invention, when any battery cell 121 in the battery module 120 is out of control due to heat, a large amount of high-temperature high-pressure gas generated in the battery module 120 flows towards the exhaust port 192 at a high flow rate, so that the detection circuit 132 of the detection device 130 arranged at the exhaust port 192 is damaged and disconnected, the signal output end 133 of the detection circuit 132 can output a circuit disconnection signal in time, and further the control device can send an alarm signal to a user of a vehicle in time, so that the response time is shortened, and the safety performance is improved. In addition, by detachably mounting the detection device 130 to the housing 110 via the support 134, the detection device 130 may be prevented from undesired movement.
As described above, although only one battery module 120 is disposed in the inner cavity of the case 110 in the preferred embodiment of the present invention, two or more battery modules 120 may be disposed in the inner cavity of the case 110. When a plurality of battery modules 120 are disposed in the inner cavity of the housing 110, the plurality of battery modules 120 may share the same exhaust channel 191, exhaust port 192, and detection device 130, or a plurality of exhaust channels 191, a plurality of exhaust ports 192, and a plurality of detection devices 130 may be correspondingly disposed to further shorten the response time. When a plurality of detection devices 130 are provided, the signal output terminals 133 of the detection circuits 132 of each detection device 130 may be connected in series and finally connected to the control device. When any battery cell 121 in any battery module 120 is out of control due to heat, a large amount of high-temperature and high-pressure gas generated in the battery module 120 can damage the detection circuit 132 of the corresponding detection device 130. Since the signal output terminals 133 of the detection circuits 132 of each of the detection devices 130 are connected in series, the damage of the detection circuit 132 of any one of the detection devices 130 can output a circuit disconnection signal to the control device, so that the control device can timely transmit an alarm signal to a user of the vehicle.
In a second aspect of the invention, a vehicle is also provided. The vehicle is provided with the battery system described above.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
While the present invention has been described in connection with the embodiments, it is to be understood by those skilled in the art that the foregoing description and drawings are merely illustrative and not restrictive of the broad invention, and that this invention not be limited to the disclosed embodiments. Various modifications and variations are possible without departing from the spirit of the invention.
