Embodiments of the present application will be further described with reference to the accompanying drawings.
Example one
Referring to fig. 1, the present embodiment provides a battery module structure for being packaged in a box 300 to form a battery box capable of replacing batteries integrally. The battery module structure comprises a bracket 110, a semiconductor cooling sheet 130 and a battery module 200, wherein the bracket 110 is used for fixing the relative position of the semiconductor cooling sheet 130 and the battery module 200, so that the semiconductor cooling sheet 130 is directly contacted with a tab 230 of the battery module 200, and the rapid heat transfer of the battery module 200 is realized.
The bracket 110 is provided with a clamping member (not shown), through which the battery module 200 can be fixedly connected. The clamping member may be a ring member, so that when the bracket 110 is engaged with the battery module 200, the clamping member is sleeved outside the battery module 200. The clip may be a hook or other partially-fitted member, and the two plate-shaped brackets 110 may be individually attached to both surfaces of the battery module 200 having the tabs 230.
The semiconductor cooling sheet 130 has a first temperature control surface 131 and a second temperature control surface 133 which are oppositely arranged, when the bracket 110 is mounted on the battery module 200, the first temperature control surface 131 faces the tab 230 of the battery module 200, and heat transfer between the semiconductor cooling sheet 130 and the tab 230 of the battery module 200 is realized through the first temperature control surface 131.

Further, since the semiconductor cooling sheet 130 and the tab 230 of the battery module 200 are made of hard materials, if the surface of the semiconductor cooling sheet 130 is directly attached without performing a fine shape treatment, the heat dissipation area between the semiconductor cooling sheet 130 and the tab 230 may be affected, and thus the heat transfer efficiency may be affected. Therefore, the gap between the semiconductor cold block 130 and the tab 230 is filled with a heat conductive filler 250 formed of heat conductive silicone gel.

In order to achieve precise adjustment of the power of the semiconductor cooling sheet 130, it is also necessary to connect the temperature condition of the battery module 200 itself, and the battery module 200 itself has the temperature sensor 400. The battery module 200 includes a plurality of stacked battery cells 210, and the temperature sensor 400 in the battery module 200 is disposed between two adjacent battery cells 210.
Furthermore, a temperature sensor 400 is further disposed on the first temperature control surface 131 of the semiconductor cooling sheet 130, and all the temperature sensors 400 and the semiconductor cooling sheet 130 are connected to a battery management system. The battery management system determines the current temperature of the battery module 200 and the first temperature control surface 131 through the temperature sensor 400, and then controls the power supply to the semiconductor cooling sheet 130, so as to precisely adjust the cooling rate and the heating rate of the semiconductor cooling sheet 130 to the battery module 200.
The application provides a battery module structure carries out the heat transfer through semiconductor refrigeration piece 130 to battery module 200's utmost point ear 230, realizes rapid cooling, the intensification to battery module 200's electric core 210, has avoided semiconductor refrigeration piece 130 to lead to the disadvantage that heat transfer efficiency is low through battery module 200's surface heat transfer. And set up temperature sensor 400, can let the opening power of each semiconductor refrigeration piece 130 of battery management system fine control, lower the temperature, heat up battery module 200's electric core 210 to with the temperature difference control between electric core 210 and the electric core 210 in reasonable scope.
