[0060] Specifically, the housing 13 has a receiving space 15, the mounting plate 23 is located in the receiving space 15, the battery cell module 21 and the battery management module 22 are respectively installed in the receiving space 15, the battery management module 22 is electrically connected to the battery cell module 21, the battery management module 22 includes a circuit board 221, a total negative high-voltage connector input terminal 222, a total negative high-voltage connector output terminal 223, and a low-voltage acquisition terminal 224, the battery management module 22 is disposed on the mounting plate 23, and the heat dissipation module 25 is disposed on one side of the circuit board 221 close to and / or away from the mounting plate 23.

[0061] In other words, the starting power supply 1 according to an embodiment of the present application mainly consists of a housing 13, a mounting plate 23, a battery cell module 21, a battery management module 22, and a heat dissipation module 25. The housing 13 has a receiving space 15, and a battery system 2 is installed in the receiving space 15.

Specifically, the heat dissipation module 25 can be installed on one side of the circuit board 221 close to and / or away from the mounting plate 23. The heat dissipation module 25 can dissipate heat from the circuit board 221. Among them, when the circuit board 221 is arranged on the side close to the mounting plate 23, the heat dissipation module 25 can dissipate heat from both the circuit board 221 and the mounting plate 23 simultaneously. Optionally, a gap is formed between the heat dissipation module 25 and the mounting plate 23 through a support column to improve the heat dissipation effect; when the circuit board 221 is arranged on the side away from the mounting plate 23, it can at least dissipate heat from the circuit board 221. For example, it can also cool the wiring positions connected to the circuit board 221; when the mounting plate 23 is a heat-conducting material part, it can also dissipate heat from the battery cell module 21 installed near the mounting plate 23.

[0063] Thus, in this embodiment, by using the heat dissipation module 25, the battery management module 22 can be dissipated heat, the working efficiency of the battery management module 22 can be improved, the influence of too high temperature on the battery management module 22 can be avoided, etc., and the safety performance of the starting power supply 1 can be improved.

[0064] According to an embodiment of the present application, the heat dissipation module 25 includes a first heat dissipation part 251. The first heat dissipation part 251 is located between the circuit board 221 and the mounting plate 23. One side of the first heat dissipation part 251 close to the mounting plate 23 has a plurality of heat dissipation protrusions 252 distributed at intervals. A heat dissipation channel can be formed between two adjacent heat dissipation protrusions 252. In this embodiment, by using the first heat dissipation part 251 including a plurality of heat dissipation protrusions 252, the heat dissipation efficiency is improved through the heat dissipation channel.

[0065] In some specific embodiments of the present application, the plurality of heat dissipation protrusions 252 are distributed at intervals along the extension direction of the circuit board 221. For example, the width direction of the circuit board 221 is the front-back direction, and the plurality of heat dissipation protrusions 252 are distributed at intervals along the front-back direction. In this embodiment, by using the plurality of heat dissipation protrusions 252 distributed at intervals along the extension direction of the circuit board 221, it is beneficial to expand the heat dissipation area for the circuit board 221.

[0066] According to an embodiment of the present application, the heat dissipation module 25 includes: a second heat dissipation part 253.

An avoidance groove 2531 is provided at the outer edge of the second heat dissipation part 253 for avoiding the high-voltage terminal 2216. In this embodiment, by providing the avoidance groove 2531 at the outer edge of the second heat dissipation part 253, it is possible to prevent interference between the second heat dissipation part 253 and the high-voltage terminal 2216.

[0069] In some specific embodiments of the present application, two protruding limiting protrusions 2211 are provided on the circuit board 221. For example, two limiting protrusions 2211 are provided along the width direction of the circuit board 221. The two limiting protrusions 2211 are spaced apart and form a limiting groove 2212 for installing a low-voltage acquisition wire harness connector for connecting the low-voltage acquisition end 224. In this embodiment, by the cooperation of the two limiting protrusions 2211, the limiting groove 2212 can be formed, so as to limit the low-voltage acquisition wire harness connector.

[0070] According to an embodiment of the present application, a plurality of high-voltage terminals 2216 are respectively provided on the relatively arranged first edge 2213 and second edge 2214 of the circuit board 221, that is to say, the plurality of high-voltage terminals 2216 are respectively provided on the relatively arranged first edge 2213 and second edge 2214 of the circuit board 221. A limiting groove 2212 is provided on the third edge 2215 of the circuit board 221, that is to say, the limiting groove 2212 is provided on the third edge 2215 of the circuit board 221.

[0071] In this embodiment, by respectively providing the high-voltage terminals 2216 on the first edge 2213 and the second edge 2214 and providing the limiting groove 2212 on the third edge 2215, not only can the utilization rate of the circuit board 221 be improved, but also it is beneficial to the quick positioning of the high-voltage terminals 2216 and the wire harnesses, etc. Moreover, by arranging the high-voltage terminals 2216 and the limiting groove 2212 at the edge positions, the length of the connection line 4 can be reduced, and the heat dissipation effect of the wiring position can be improved.

[0072] In some specific embodiments of the present application, the mounting plate 23 divides the accommodation space 15 into a first accommodation cavity 151 and a second accommodation cavity 152 in a first direction. The battery cell module 21 is mounted in the first accommodation cavity 151, and the battery management module 22 is mounted in the second accommodation cavity 152. For example, when the first direction is the vertical direction, the mounting plate 23 can divide the accommodation space 15 into the first accommodation cavity 151 and the second accommodation cavity 152 in the first direction. The first accommodation cavity 151 is used to accommodate the battery cell module 21, and the second accommodation cavity 152 is used to accommodate the battery management module 22.
