Specifically, the battery assembly includes a battery cell 11 and a circuit board 10, wherein the circuit board 10 is connected to the battery cell 11 through a connection element 12. Specifically, the connection element 12 is an electrode lead drawn from the battery cell 11. In one embodiment, the cell 11 is provided with an electrode tab, the circuit board 10 is provided with a pad, and the connecting element 12 has one end connected to the electrode tab to connect with the cell 11 and the other end connected to the pad to connect with the circuit board 10, thereby electrically connecting the cell 11 with the circuit board 10.
In order to reduce the heat that circuit board 10 transmitted to electric core 11 for electric core 11 surface ambient temperature is less than the specification temperature and so does not influence the speed of charging, the battery pack of this application further sets up heat isolation structure around circuit board 10, so that circuit board 10 and electric core 11 form the heat and keep apart, and then reduces circuit board 10 and transmits the heat to electric core 11, makes electric core 11 surface ambient temperature be less than the specification temperature and so does not influence the speed of charging. In a specific embodiment, the heat insulating structure covers at least two opposite surfaces of the wiring board 10, or is disposed around the wiring board 10 in the axial direction L of the battery pack.
Specifically, referring to fig. 2, the battery assembly further includes a support 15 and a sealing cover 14, and the support 15 and the sealing cover 14 cooperate to form a heat insulation structure. Specifically, the bracket 15 includes a first receiving groove 13 and a second receiving groove 16.

Specifically, the sealing cover 14 and the bottom wall 131 of the first accommodating groove 13 and the annular side wall jointly form a heat isolation structure, the heat isolation structure is arranged around the circuit board 10, the circuit board 10 can be wrapped, the circuit board 10 is further isolated from the battery cell 11, and therefore the heat transmitted to the battery cell 11 by the circuit board 10 can be reduced, so that the surface environment temperature of the battery cell 11 is lower than the specification temperature, and therefore the charging speed is not affected. Further, the sealing cover 14 covers the whole port of the first accommodating groove 13 on the side of the circuit board 10 away from the bottom wall 131 of the first accommodating groove 13, so as to completely isolate the circuit board 10 from the battery cell 11, and thus, heat isolation is formed between the circuit board 10 and the battery cell 11.
Further, the battery assembly further includes a silicone cover 17, and the silicone cover 17 is located in the first receiving groove 13 and located between the circuit board 10 and the sealing cover 14. The silica gel cover 17 can strengthen the sealing performance of the heat isolation structure, and the first accommodating groove 13 and the sealing cover 14 are matched to form the heat isolation structure to encapsulate the circuit board 10, so that the heat generated by the circuit board 10 is further prevented from being dissipated to the battery cell 11. The size and thickness of the silicone cover 17 is not limited, and in one embodiment, the silicone cover 17 covers the entire circuit board 10 and has a thickness equal to the distance between the circuit board 10 and the sealing cover 14.
Further, a common sidewall is disposed between the first receiving groove 13 and the second receiving groove 16, and the common sidewall is a first sidewall 132 of the first receiving groove 13. The common sidewall (the first sidewall 132) has an opening 18, and the opening 18 may be a notch on the common sidewall or a through hole penetrating through the common sidewall. The connecting element 12 is a wire, one end of which is electrically connected to the battery cell 11, and the other end of which passes through the opening 18 and is electrically connected to the circuit board 10.
In an embodiment, in order to reduce the amount of heat transferred from the circuit board 10 to the battery cell 11, so that the ambient temperature on the surface of the battery cell 11 is lower than the specification temperature, and thus the charging speed is not affected, the cross-sectional area of the opening 18 is less than 30% of the cross-sectional area of the battery cell 11, for example, the cross-sectional area of the opening 18 is less than 15% of the cross-sectional area of the battery cell 11.
In another embodiment, in order to reduce the heat transferred from the circuit board 10 to the battery cell 11, so that the ambient temperature on the surface of the battery cell 11 is lower than the specification temperature, and thus the charging speed is not affected, the heat of the component of the circuit board 10 close to the opening 18 is smaller than that of the component far from the opening 18, that is, the side of the circuit board 10 with smaller heat is disposed close to the opening 18, and the side with larger heat is disposed close to the second sidewall 133.
In the battery assembly of the present embodiment, the bottom wall 131, the first side wall 132 and the second side wall 133 of the first receiving groove 13 cooperate with the silicone cover 17 and the sealing cover 14 to form a heat isolating structure, so that the circuit board 10 is half-packaged in the first receiving groove 13. The first side wall 132 has an opening 18, and the connecting element 12 passes through the opening 18 to connect the battery cell 11 with the circuit board 10, so that the heat transferred from the circuit board 10 to the battery cell 11 can be reduced, and the ambient temperature on the surface of the battery cell 11 is lower than the specification temperature, so that the charging speed is not affected.
Referring to fig. 3, fig. 3 is a sectional view of a second embodiment of the battery assembly shown in fig. 1 along direction a-a. Compared with the embodiment shown in fig. 2, the present embodiment is different in that the opening 18 is not disposed at the first sidewall 132 of the first receiving groove 13. Specifically, the bottom wall 131 and the annular side wall of the first receiving groove 13 cooperate with the silicone cover 17 and the sealing cover 14 to form a heat isolating structure, so that the circuit board 10 is completely encapsulated in the first receiving groove 13. In this embodiment, in order to realize the electrical connection between the circuit board 10 and the battery cell 11, the connecting element 12 is a metal elastic sheet embedded in the side wall of the bracket 15. Specifically, as shown in fig. 3, the connecting element 12 may be embedded in the bottom wall 131 of the first receiving groove 13, and specifically, the metal elastic sheet may be disposed in the wall of the bottom wall 131 of the first receiving groove 13 by injection molding.
One end of the metal elastic sheet extends into the first accommodating groove 13 to be electrically connected with the circuit board 10, and the other end of the metal elastic sheet extends out of the first accommodating groove 13 to be electrically connected with the battery cell 11. Specifically, the other end of the metal elastic sheet may directly extend into the second accommodating groove 16 to be electrically connected with the battery cell 11; or the other end of the metal elastic sheet may also extend to a position between the first accommodating groove 13 and the second accommodating groove 16 to be connected with the exposed electrode lug of the battery cell 11, which is not limited specifically. Because the metal elastic sheet has elasticity and the main body part is embedded in the side wall of the bracket 15, the assembly process of the battery assembly can be simplified by the elastic abutting of the end part of the metal elastic sheet and the electrode lug of the battery cell 11 or the bonding pad on the circuit board 10.
In the battery assembly of the present embodiment, the bottom wall 131, the first side wall 132 and the second side wall 133 of the first receiving groove 13 cooperate with the silicone cover 17 and the sealing cover 14 to form a heat isolating structure, so that the circuit board 10 is completely encapsulated in the first receiving groove 13. The connecting element 12 is a metal elastic sheet embedded in the side wall of the bracket 15, one end of the metal elastic sheet extends into the first accommodating groove 13 and is electrically connected with the circuit board 10, and the other end of the metal elastic sheet extends out of the first accommodating groove 13 and is electrically connected with the battery cell 11. Therefore, the heat transferred to the battery cell 11 by the circuit board 10 can be reduced, so that the ambient temperature on the surface of the battery cell 11 is lower than the specification temperature, and the charging speed is not influenced.
