A battery module 100 according to an embodiment of the present invention is described below in a specific embodiment with reference to fig. 1 to 10. It is to be understood that the following description is illustrative only and is not intended as a specific limitation on the invention.

According to some embodiments of the present invention, as shown in fig. 3, the battery module 100 includes a battery pack 110, a sampling circuit board 120, an end plate 130, a protective sheath 160, a first temperature sensor 140, and a second temperature sensor 150. It should be noted that the battery pack 110 includes a plurality of unit cells arranged in sequence.

Specifically, the battery pack 110 has a first surface 111, a second surface, and a third surface. The first surface 111 is opposite to the third surface, the second surface has a first edge 1121 and a second edge opposite to the first surface, the first edge 1121 is connected to the first surface 111, and the second edge is connected to the third surface. For example, as shown in fig. 1, the first surface 111 is a surface located at an upper portion of the battery pack 110 (an upper surface as shown in fig. 1), that is, the first surface 111 is a top surface; the second surface is a surface (front side surface as shown in fig. 1) located at the front of the battery pack 110, that is, the second surface is a front side surface; the third surface is located at the bottom (the lower position as shown in fig. 1) of the battery pack 110, that is, the third surface is a bottom surface. Further, an edge of an upper end of the second surface is a first edge 1121, the first edge 1121 is connected to the first surface 111, and an edge of a lower end of the second surface is a second edge, and the second edge is connected to the third surface.

The sampling circuit board 120 is disposed on the first surface 111, the end plate 130 is disposed on the second surface, and the first temperature sensor 140 is disposed on the sampling circuit board 120. Thus, the temperature of the first surface 111 may be monitored with the first temperature sensor 140. For example, as shown in fig. 1, the first temperature sensor 140 may be provided at the middle of the battery pack 110. In order to make the temperature detected by the first temperature sensor 140 closer to the battery pack 110, the first temperature sensor 140 may be in contact with the battery pack 110.

The second temperature sensor 150 is disposed on the end plate 130 and adjacent to the bottom end of the end plate 130, and the second temperature sensor 150 is electrically connected to the sampling circuit board 120 through a sampling line 151. Thus, the temperature of the bottom of the battery pack 110 may be monitored using the second temperature sensor 150, that is, the temperature sampling points of the battery module 100 may be increased. It should be noted that the sampling line 151 may be a conductive wire, a conductive metal sheet, a conductive metal layer, or the like.

In order to facilitate the electrical connection between the sampling line 151 and the sampling circuit board 120, a socket 152 may be disposed at an end of the sampling line 151, and the socket 152 is plugged into the sampling circuit board 120. Here, the sampling circuit board 120 may be a flexible sampling circuit board 120, or may be a hard sampling circuit board 120; socket 152 may be a 2pin connector. In order to make the temperature detected by the second temperature sensor 150 closer to the battery pack 110, the second temperature sensor 150 may be in contact with the battery pack 100.

Therefore, the temperature of the first surface 111 is monitored by the first temperature sensor 140, and the temperature of the position where the first temperature sensor is located is monitored by the second temperature sensor 150, so that the sampling data of the temperature sensors can be increased, and the value closer to the actual temperature of the battery module 100 is obtained according to the monitoring temperature values of the first temperature sensor 140 and the second temperature sensor.

As shown in fig. 3, a second temperature sensor 150 is located at the second edge. The temperature near the second edge can thus be monitored using the second temperature sensor 150, thereby solving the problem that the temperature sensor is difficult to detect the local temperature of the battery pack 110. For example, the second edge may be located at the bottom of the battery pack 110, that is, the second temperature sensor 150 may be used to detect the temperature at the bottom of the battery pack 110, so that the first temperature sensor 140 is used to monitor the temperature of the first surface 111, and the second temperature sensor 150 is used to monitor the temperature at the bottom of the battery pack 110, so that the temperature of the battery module 100 may be sampled from a plurality of sampling positions, and the temperature state of the battery module 100 may be accurately measured.

In some examples, in order to facilitate wiring, the second temperature sensor 150 is electrically connected to the sampling wiring board 120 through a sampling line 151, and the sampling line 151 may be attached to the end plate 130, thereby preventing the sampling line 151 from shaking. Of course, the arrangement of the sampling lines 151 is not limited to this.

As shown in fig. 2 and 3, a partial segment of the sampling line 151 passes through the end plate 130. It will be appreciated that the end plate 130 has a thickness and that a partial section of the sampling line 151 may be threaded into the interior of the end plate 130. On one hand, the end plate 130 can be used for protecting the sampling line 151, so that the sampling line 151 is prevented from being broken and the like caused by collision and extrusion when the battery pack 110 is assembled on the end plate 130; on the other hand, the sampling lines 151 can be accommodated in the space of the end plate 130 in the thickness direction, so that the situation that the volume of the battery module 100 is increased due to the fact that the separately-arranged sampling lines 151 occupy a certain space volume can be avoided, and the accommodating characteristic and the supporting protection characteristic can be integrated on the end plate 130, so that the structure of the battery module 100 is simplified, and the space occupied by the battery module 100 is reduced.

In order to facilitate the penetration of the sampling line 151 into the end plate 130, as shown in fig. 3 to 5, the end plate 130 may have a hollow structure inside. As shown in fig. 3-5, the end plate 130 includes first and second spaced-apart

plates

133, 134 with the sampling line 151 sandwiched between the first and

second plates

133, 134. In order to reinforce the stability of the connection between the first plate 133 and the second plate 134, a connection rib 135 is connected between the first plate 133 and the second plate 134.

As shown in fig. 3, 4, and 7, the protective sheath 160 is embedded inside the end plate 130, and a partial section of the sampling line 151 is inserted through the protective sheath 160. On one hand, the sample line 151 may be protected by a protective sheath 160 to prevent the sample line 151 from interfering with the structure inside the end plate 130; on the other hand, when the sampling line 151 is assembled to the end plate 130, the sampling line 151 may be first inserted into the protective sheath 160, and the protective sheath 160 and the sampling line 151 are inserted into the end plate 130 together, so that the sampling line 151 may smoothly pass through the end plate 130 by using the guiding function of the protective sheath 160.

Further, as shown in fig. 5, the protective sheath 160 is disposed in the routing channel 131. On one hand, the protective sleeve 160 can be protected by the sidewall of the routing channel 131 to prevent the protective sleeve 160 from interfering with the structure inside the end plate 130; on the other hand, the protective sheath 160 can be guided by the routing channel 131, so that the protective sheath 160 can be inserted into the end plate 130 smoothly.

As shown in fig. 3 and 6, the end plate 130 has a bottom opening 132, the bottom opening 132 is open toward the second surface, and a part of the structure of the second temperature sensor 150 protrudes from the bottom opening 132. It is understood that the notch 165 of the protective cover 160 may be opposite to and communicate with the bottom opening 132 of the end plate 130, the second temperature sensor 150 may be disposed in the protective cover 160, a part of the structure of the second temperature sensor 150 protrudes from the protective cover 160 through the notch 165, and the part of the protruding structure passes through the bottom opening 132 and protrudes from the bottom opening 132, that is, a part of the structure of the second temperature sensor 150, may be exposed from the end plate 130, so as to facilitate the second temperature sensor 150 to detect the temperature of the battery pack 110.

Further, as shown in fig. 3, 7, and 8, the protective sleeve 160 may have an elongated cylindrical structure, and the protective sleeve 160 may penetrate the end plate 130 in the up-down direction (the up-down direction shown in fig. 3). The protective sheath 160 ends at the first edge 1121 as a first end 162 and ends at a second end 164. In other words, the first end 162 of the protective sheath 160 is proximate the first edge 1121 and the other end of the protective sheath 160 is the second end 164. That is, as shown in fig. 3, the end of the protective sheath 160 near the upper end edge of the endplate 130 is a first end 162, and the end of the protective sheath 160 near the lower end edge of the endplate 130 is a second end 164. As shown in fig. 7, 8 and 10, the first end 162 has a flange 163. As shown in fig. 3, the flange 163 abuts the surface of the end plate 130 at the first edge 1121. That is, the flanges 163 and the end plate 130 abut against each other, so that the protective sleeve 160 can be prevented from falling into the end plate 130 or the protective sleeve 160 can be prevented from falling off from the lower end of the end plate 130.

As shown in FIG. 8, the sidewall of the protective sheath 160 has a slot 161. It should be noted that when the sampling wire 151 is inserted into the protective sheath 160, the sampling wire 151 may be knotted or twisted in the protective sheath 160, so that the sampling wire 151 is difficult to pass through the protective sheath 160, and by providing the slot 161, the state of the sampling wire 151 inside the protective sheath 160 can be adjusted by using the slot 161, so that the sampling wire 151 can smoothly pass through the protective sheath 160. Further, as shown in fig. 8, a slot 161 may be provided in the middle of the protective sheath 160. Further, the slot 161 may have an elongated shape and may extend along the length of the protective sheath 160.

As shown in fig. 7 and 9, the second end 164 has a notch 165, the notch 165 is open toward the battery pack 110, and a portion of the second temperature sensor 150 protrudes from the notch 165. It should be noted that the second temperature sensor 150 can be exposed from the protective sleeve 160, so that the second temperature sensor 150 can be closer to the battery pack 110, and the temperature value monitored by the second temperature sensor 150 can be closer to the actual temperature of the battery module 100. Specifically, the notch 165 may be provided at an edge of the second end 164 to facilitate machining the notch 165 at the second end 164.

To promote stability of the assembly between the protective sleeve 160 and the endplate 130, as shown in fig. 3, a resilient cantilever 166 is provided within the notch 165 of the protective sleeve 160.

Further, as shown in fig. 3, the elastic cantilever 166 is provided at the edge of the notch 165, and the elastic cantilever 166 extends toward the inside of the notch 165. In order to raise the resisting force between the elastic cantilever 166 and the end plate 130, the free end of the elastic cantilever 166 may have a protruding structure 1661, and the protruding structure 1661 protrudes toward the battery pack.
