When the width of the accommodating space 4 is 2 times of the width of the soft package battery 6, it can be understood that the accommodating space 4 can be used for placing two soft package battery 6 side by side, no heating film 1 is arranged between the two soft package battery 6, and two exposed side walls of the two soft package batteries are respectively provided with the heating films 1, that is, each heating film 1 can only heat the soft package battery 6 adjacent to the heating film 1.
When the width of the accommodating space 4 is 3 times of the width of the soft package battery packs 6, it can be understood that the accommodating space 4 can be used for placing three soft package battery packs 6 side by side, no heating film 1 is arranged between every two adjacent soft package battery packs 6 in the three soft package battery packs 6, and two exposed side walls of the three soft package battery packs are respectively provided with the heating film 1, namely, the heating film 1 can only heat the soft package battery packs 6 adjacent to the heating film 1 at the moment, which is equivalent to that the middle soft package battery pack 6 is not directly heated by the heating film 1; further, the pouch battery 6 in the middle in the same accommodating space 4 may heat the pouch battery 6 in the middle by heat possessed by the pouch battery 6 on both sides adjacent thereto in a thermally conductive manner.
Notably, are: the widths of the three accommodation spaces 4 (the first accommodation space, the second accommodation space, and the third accommodation space) formed as described above may be the same or different.
In this embodiment, as shown in fig. 6, four heating films 1 are arranged in a first preset path 3 with axes on a straight line, so that the arrangement can be adapted to a structure in which a plurality of soft pack battery packs 6 are arranged side by side along the straight line.
Notably, are: the four heating films 1 are not limited to being arranged in the first preset path 3 with the axis on a straight line, but may be: the four heating films 1 are arranged in a first preset path 3 with axes parallel to each other.
In this embodiment, the heating film 1 can release heat after being heated, in order to prevent the heat dissipation of the heating film 1, and influence the heating effect of the heating film 1 on the soft package battery pack 6, and then the thermal insulation film 7 is stuck on one side of the heating film 1 far away from the soft package battery pack 6, and the setting of the thermal insulation film 7 can greatly reduce the heat dissipation of the heating film 1, and then can efficiently heat the soft package battery, shorten the heating time, and save energy efficiency.
Further, the heat-insulating film 7 is adhered to the heating film 1 by an adhesive back glue.
Example five
An integrated heating assembly is described in detail in this embodiment in connection with fig. 7.
In particular, the integrated heating assembly comprises two integrated heating members 9 as set forth in embodiment one, the two integrated heating members 9 being arranged with the second preset path 8 with the axis on a straight line.
Specifically, the first connectors 2 connected to the heating film 1 at the end of the second preset path 8 are respectively in communication with the positive and negative poles of the power supply; the adjacent heating films 1 of the adjacent integrated heating members 9 are connected by a second connector 10.
In summary, the integrated heating element 9 may be used as a heating unit, and the two heating units are connected by using the second connector 10; further, the integrated heating assembly in fig. 7 has four heating films 1, the four heating films 1 being equipped with 2 first connectors 2 and one second connector 10; compared with the prior art, each heating film 1 is independently used as a unit, namely, each heating film 1 is independently connected with a master control circuit by two first connectors 2 (eight first connectors 2 are needed for four heating films 1), the number of the connectors is greatly reduced, the cost is saved, and the connection reliability can be ensured.
Further, adjacent heating films 1 in adjacent integrated heating members 9 are close together.
Further, fig. 8 shows an integrated heating assembly consisting of the integrated heating member 9 described in the first three embodiments.
Example six
An integrated heating assembly is described in detail in this embodiment in connection with fig. 9.
In particular, the integrated heating assembly comprises two integrated heating members 9 as set forth in embodiment three, the two integrated heating members 9 being arranged with the second preset path 8 with the axis on a straight line.
Specifically, the first connectors 2 connected to the heating film 1 at the end of the second preset path 8 are respectively in communication with the positive and negative poles of the power supply; the adjacent heating films 1 of the adjacent integrated heating members 9 are connected by a second connector 10.
In summary, the integrated heating element 9 may be used as a heating unit, and the two heating units are connected by using the second connector 10; further, the integrated heating assembly in fig. 9 has 8 heating films 1, and the 8 heating films 1 are provided with 2 first connectors 2 and one second connector 10; compared with the prior art, each heating film 1 is independently used as a unit, namely, each heating film 1 is independently connected with a master control circuit by two first connectors 2 (16 first connectors 2 are needed for 8 heating films 1), the number of the connectors is greatly reduced, the cost is saved, and the connection reliability can be ensured.
Further, adjacent heating films 1 in adjacent integrated heating members 9 are close together.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
