It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0037] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] Embodiment 1

[0039] The embodiment of the utility model provides a CCS component, which can effectively improve the temperature measurement accuracy of the temperature measuring component 2 on the battery.

[0040] See also Figures 1 to 8The CCS assembly includes a flexible circuit board 1 and a temperature measuring element 2; the flexible circuit board 1 includes a body 11 and a first elastic extension 12 connected to the body 11; a first window 111 is provided inside the body 11, one end of the first elastic extension 12 is connected to the side of the first window 111, and the other end extends in a direction parallel to the first direction to form a suspended portion 121, and the temperature measuring element 2 is installed on the suspended portion 121; a bending portion 122 is also provided on the first elastic extension 12, and the bending portion 122 makes the suspended portion 121 protrude from the body 11, so as to elastically press the temperature measuring portion of the temperature measuring element 2 against the top cover of the battery. Figures 1 to 4 It can be seen that the CCS assembly is located on the top side of the battery pack, and an insulating tray is provided between the battery pack and the CCS assembly, and the insulating tray can prevent the body 11 from directly contacting the batteries in the battery pack. Figures 5 to 7 , it is clearly stated that the first direction is the length direction of the body 11.

[0041] On the one hand, the first elastic extension part 12 extends in a direction parallel to the first direction, and the bending part 122 is provided, so that the elastic deformation ability of the first elastic extension part 12 is stronger. When the CCS assembly is assembled on the battery, even if the body 11 is pulled and deformed due to external handling, transportation, use or other reasons, the temperature measuring element 2 can still be well maintained in a suitable temperature measurement position and keep in contact with the top cover of the battery, that is, the small pulling deformation of the first elastic extension part 12 will not change the relative position of the temperature measuring element 2 and the battery to be detected, and the temperature measuring element 2 can still be maintained in a suitable detection temperature position to ensure the accuracy of temperature measurement; on the other hand, the bending part 122 is provided, so that the temperature measuring part of the temperature measuring element 2 can directly contact the top cover of the battery, that is, the temperature measuring element 2 can directly measure the temperature of the top cover, so as to more accurately confirm the actual temperature of the battery; at the same time, the first elastic extension part 12 is provided inside the flexible circuit board 1, which is convenient for setting the position of the temperature measuring element 2, so that it is far away from the pole of the battery, avoiding the influence of the high temperature of the pole on the temperature measuring element 2, and ensuring the accuracy of temperature measurement. 。 It should be noted that the prior art generally detects the temperature of the bar connected to the pole to indirectly determine the temperature of the battery. The temperature measurement method in this embodiment is obviously more accurate than the temperature measurement method in the prior art. In the structure of this embodiment, the temperature measuring element 2 can directly collect the temperature of the top cover of the battery, reduce the intermediate heat transfer path, and the detected temperature is closer to the actual temperature of the battery.

[0042] Optionally, the first elastic extension portion 12 includes a connection portion 123 connected to the main body 11, and the connection portion 123, the bending portion 122 and the suspended portion 121 are sequentially connected to form the first elastic extension portion 12, and the connection portion 123 is bent and extended in a serpentine shape; the temperature measuring component 2 is arranged on the side of the suspended portion 121 facing the main body 11. The connection portion 123 is bent and extended in a serpentine shape, and the first elastic extension portion 12 is provided with a bending portion 122, so that the elastic deformation effect of the first elastic extension portion 12 in the first direction and the up and down directions is relatively good, so as to better ensure that the temperature measuring component 2 contacts the battery to maintain the temperature measurement state, and ensure the temperature measurement accuracy of the temperature measuring component 2. In addition, the temperature measuring component 2 is arranged on the side of the suspended portion 121 facing the main body 11, which is convenient for disassembly and assembly on the one hand, and can effectively improve the convenience of observing whether the temperature measuring component 2 is installed on the suspended portion 121 during the assembly process to prevent missing installation. It should also be noted that the suspended portion 121 on which the temperature measuring element 2 is installed is covered with a heat conducting element, and the heat conducting element is directly connected to the battery top cover, thereby transferring the temperature of the battery top cover to the temperature measuring element 2 .

[0043] Optionally, a plurality of first elastic extensions 12 are spaced apart on the body 11 along the first direction, and the extension length of the first elastic extension 12 at the end is greater than the extension length of the other first elastic extensions 12. Figure 5 As shown, the first elastic extensions 12 are arranged at intervals to detect the temperature of different batteries. It should also be noted that the extension length of the first elastic extension 12 at the end is greater than the extension length of other first elastic extensions 12, which can be more conducive to improving the buffering effect of the first elastic extension 12 at the end. Because during the assembly process, due to the errors in production and assembly, the pulling force on the first elastic extension 12 at the end is generally the largest, so the first elastic extension 12 at the end is set longer, which can effectively improve the buffering effect.

[0044] Optionally, the connection portion 123 is parallel to the surface of the body 11, and the suspended portion 121 is parallel to the surface of the body 11; the surface of the body 11 refers to the side of the body 11 with a larger area, that is, the body 11 is a sheet structure, and the surface specifically refers to the side with a larger area, and the body 11 has two opposite side surfaces. In this embodiment, the connection portion 123 is parallel to the surface of the body 11, and the suspended portion 121 is parallel to the surface of the body 11, so that the installation of the flexible circuit board 1 can be facilitated, and the temperature measuring component 2 can be more conveniently installed on the suspended portion 121. In order to improve the connection stability, a reinforcement member can be further provided on the side of the suspended portion 121 close to the battery top cover, so that the suspended portion 121 fits tightly against the battery top cover to improve the temperature measurement accuracy.

[0045] Optionally, the CCS assembly further includes a voltage detection member 3 for detecting the battery voltage; the flexible circuit board 1 further includes a second elastic extension 13 connected to the body 11, the first side edge of the body 11 parallel to the first direction is recessed to form a second window 112, one end of the second elastic extension 13 is connected to the side edge of the second window 112, and the other end extends in a direction parallel to the first direction to form a suspended end; the voltage detection member 3 is installed on the suspended end. Figure 1 and Figure 2 It can be seen that the second window 112 is arranged on the side of the main body 11, so that the voltage detection component 3 is directly connected to the bar connected to the battery pole, and the voltage detection component 3 is located on the side of the second elastic extension 13 close to the battery. The first window 111 is arranged inside the main body 11, so that the temperature measuring component 2 is away from the battery pole and the battery pack, thereby improving the temperature measurement accuracy. The second elastic extension 13 connects and supports the voltage detection component 3, and the first elastic extension 12 connects and supports the temperature measuring component 2. The temperature measuring component 2 and the voltage detection component 3 do not interfere with each other, which can help improve the temperature measurement accuracy and side pressure accuracy, especially avoiding the situation where too much heat dissipated by the side pressure circuit is transferred to the temperature measuring component 2 and greatly affects the temperature measurement accuracy. In addition, if the voltage detection component 3 is installed on the suspended end, the stability of the voltage detection component 3 connecting to the battery bar can be effectively maintained, thereby improving the accuracy of battery voltage detection.

[0046] Optionally, the second elastic extension portion 13 extends in a serpentine shape, and a set height difference is provided between the bottom surface of the suspended end and the top surface of the suspended portion 121, thereby ensuring that the temperature measuring element 2 and the voltage detecting element 3 can be normally detected. For batteries of different specifications, the set height difference can be flexibly changed.

[0047] Optionally, the second elastic extension 13 is parallel to the body 11, that is, the second elastic extension 13 does not protrude from the board surface of the body 11. Of course, the second elastic extension 13 can also be partially protruded according to actual needs, such as a structure similar to the first elastic extension 12, as long as the second elastic extension 13 maintains a serpentine bend. Preferably, the second elastic extension 13 has an inclined extension portion, and the inclined extension portion makes the suspended end protrude from the board surface of the body 11.

[0048] Optionally, the second window 112 and the first window 111 are interconnected through a connection gap 113; the adjacent suspended portions 121 and suspended ends are arranged side by side, and are arranged on opposite sides of the same connection gap; the distance between the temperature measuring component 2 and the voltage detecting component 3 in the first direction is less than a predetermined distance. It should be particularly noted that the second window 112 and the first window 111 are interconnected through the connection gap 113, so that the installation buffer between the temperature measuring component 2 and the voltage detecting component 3 can be effectively superimposed, that is, if there is a large deviation in the installation position of the battery, it can also effectively prevent the occurrence of tearing accidents, and the temperature measuring component 2 and the voltage detecting component 3 can also be more accurately installed in the appropriate position, and the distance between the temperature measuring component 2 and the voltage detecting component 3 in the first direction is less than the predetermined distance, and further, it can be less than the thickness of the battery along the first direction, so that the temperature measuring component 2 and the voltage detecting component 3 can accurately detect the same battery, avoiding the situation where the same battery cannot be detected due to the unreasonable arrangement of the second window 112 and the first window 111. The tearing accident refers to the excessive deviation of the installation position between the temperature measuring component 2 and the voltage detecting component 3, resulting in tearing of the body 11.

[0049] Optionally, the second elastic extension portion 13 and the first elastic extension portion 12 extend in opposite directions. Figure 6 As shown, the second elastic extension portion 13 extends along the first direction, and the first elastic extension portion 12 extends in the opposite direction of the first direction. This facilitates wiring on the flexible circuit board 1 and facilitates production, and is also beneficial to improving the overall strength of the flexible circuit board 1.

[0050] Optionally, the connection gap 113 is provided at least at two ends of the body 11, and the first direction is the extension direction of the body 11. The connection gap 113 is perpendicular to the first direction and is provided with a suspended portion 121 and a suspended end at two opposite ends, respectively, which can reduce the distribution range of the first window 111 and the second window 112, save space, and facilitate the isolation of the temperature measuring component 2 and the voltage detecting component 3, thereby improving the detection accuracy. In this embodiment, the connection gap 113 is provided at two ends of the body 11, which can effectively ensure the buffering effect of the installation of the suspended portion 121 and the suspended end at both ends, further increase the installation stability, and reduce the possibility of tearing accidents.

[0051] Alternatively, if Figure 5 and Figure 6As shown, the first elastic extension 12 and the second elastic extension 13 are located on the same side of the body 11, so that the temperature detection and voltage detection can be performed on the same single battery to match the detection needs of the batteries in the battery module, that is, the temperature detection and voltage detection are performed on each battery. It should also be noted that the number of the first elastic extensions 12 of the flexible circuit board 1 can be reasonably spaced according to actual needs. Specifically, in actual use, the position and number of the first elastic extensions 12 can be reasonably set according to whether the batteries in the battery pack are in series or in parallel.

[0052] Optionally, a first connection route for connecting the temperature measuring element 2 is provided in the first elastic extension 12, and a second connection route for connecting the voltage detecting element 3 is provided in the second elastic extension 13. The first connection route extends from one end of the body 11 to the first elastic extension 12, and the second connection route bypasses the first connection route from the same end of the body 11 and extends to the second elastic extension 13, so as to respectively connect the temperature measuring element 2 and the voltage detecting element 3 on both sides of the connection gap 113 along the first direction. That is, the first connection route inside the first elastic extension 12 extends in the opposite direction of the first direction to connect the temperature measuring element 2, and at the same time, the end of the first connection route away from the temperature measuring element 2 extends along the first direction to connect the plug-in connector located at one end of the body; the second connection route of the second elastic extension extends along the first direction to connect the voltage detecting element 3, and the end of the second connection route away from the voltage detecting element 3 bypasses the connection gap 113 and extends along the first direction to connect the same plug-in connector, which is convenient for wiring, wherein the plug-in connector is used to connect with an external monitoring component to send the collected temperature and voltage information to the monitoring component.

[0053] Optionally, a voltage detection element 3 is provided on each bar of the battery module, so as to make the resistance value of the test circuit of each voltage detection element 3 substantially the same, which is also conducive to maintaining the accuracy of voltage measurement.

[0054] Optionally, in order to accurately detect the maximum temperature and the minimum temperature of each battery in the battery pack, as Figure 1 and Figure 3 As shown, temperature measuring components 2 are evenly distributed at both ends and the middle of the battery pack along the first direction. When a battery has an abnormal temperature due to overheating or overcharging, the temperature measuring component 2 next to it can detect it and report it to the system to remind the occupants. The flexible circuit board 1 of this solution is designed to adopt a long strip structure, and the temperature measuring component 2 and the voltage detection component 3 are set on the same side, which is convenient for wiring and detecting the temperature and voltage of the same battery, expanding the applicability of the flexible circuit board.

[0055] Optionally, an insulating epoxy board is provided on the crossbeam of the battery box, and the end of the flexible circuit board 1 extends to the insulating epoxy board, and the connector on the flexible circuit board 1 is mounted on the insulating epoxy board. The insulating epoxy board is embedded in the crossbeam by expansion rivets, and the flexible circuit board 1 is fixed to the insulating tray by heat riveting columns, thereby eliminating the need for a plastic bracket and reducing material costs.
