Detailed Description
Hereinafter, a battery pack with a substrate according to embodiment 1 of the present invention will be described with reference to fig. 1 and 2.
As shown in fig. 1, a battery pack 1 with a substrate according to embodiment 1 includes a plurality of batteries 2, a substrate 3, and a flexible sleeve 4.
As shown in fig. 2A and 2B, the plurality of batteries 2 are, for example, eight batteries connected in series, but not limited thereto, and any number of batteries may be connected in parallel or in series as necessary. The plurality of cells 2 in the battery pack 1 shown in fig. 1 are arranged in two rows and four columns in parallel in the axial direction. The battery pack 1 has one end at which electrode terminals of a plurality of batteries 2 are arranged, respectively.
The substrate 3 is, for example, substantially rectangular, is positioned at the center of one end of the battery pack 1, and covers a part of the electrode terminals of the battery 2. The substrate 3 is connected to the connection terminal 5 by solder on one side, and the connection terminal 5 is connected to the battery 2 by spot welding. On the substrate 3, on the side opposite to the spot welding position for electrical connection, a signal line 11 for transmitting a signal is connected by soldering, and the other end of the signal line 11 is connected to an external connector 12.
Safety regions L1 and L2 are formed on the edges of the other sides of the substrate 3, which are different from the sides connected to the signal lines 11 and the electrode terminals of the battery 2, respectively. The electronic components on the substrate are arranged in the electronic component arrangement area 31 outside the safety areas L1 and L2, and the electronic components are not arranged in the safety areas, so that the electronic components are prevented from being damaged due to the stress of the flexible sleeve 4 in the thermal shrinkage process, and the battery pack 1 is prevented from being damaged due to external force in the transportation and use processes.
The flexible sleeve 4 is a heat-shrinkable sleeve and is composed of polyolefin, and the thickness of the flexible sleeve is more than or equal to 0.6mm.
After the plurality of cells 2 are arranged into a desired battery pack, the substrate 3 is connected to the electrode terminals of the cells 2. Then, a heat shrinkage sleeve is sleeved on the battery pack, and the plurality of arranged batteries 2 and the substrate 3 are wrapped by heat shrinkage of the heat shrinkage sleeve at a temperature of 200 ℃ or more, thereby forming a battery pack. The flexible sleeve 4 formed by the heat-shrinkable sleeve is resistant to high temperature in the use process, is not easy to puncture, and can ensure the safety of the substrate.
Further, as shown in fig. 3, a buffer material 6 is provided on the side of the flexible tube 4 opposite to the installation substrate 3. The buffer material 6 covers portions of the substrate 4 other than the safety regions L1 and L2 in fig. 1. The buffer material 6 is made of, for example, a sponge material or the like, and is provided outside the flexible sleeve 4 and above the substrate 3, thereby preventing the electronic components, the pads, and the like on the substrate 3 from being damaged by external force.
Effects of embodiment 1
According to the battery pack with the substrate in embodiment 1, the battery and the substrate are wrapped by the flexible sleeve to form the battery pack, so that the battery pack is simple in structure, low in cost, convenient to process and assemble, small in size and wide in application range.
In addition, since the heat shrinkage bush is adopted, the assembled battery pack has the characteristic of high temperature resistance, and the thickness of the heat shrinkage bush is more than or equal to 0.6mm, so that the battery and the substrate can be better protected from being damaged due to external force.
Further, by having the buffer, the substrate can be protected from damage due to external force at the time of assembly and at the time of use.
And the safety area is formed at the edge of the substrate, and the electronic components on the substrate are arranged in the area outside the safety area, so that the electronic components on the substrate can be prevented from being damaged due to the stress generated in the thermal shrinkage process of the flexible sleeve, and the battery pack is prevented from being damaged due to external force in the transportation and use processes.
The configuration of embodiment 2 is basically the same as that of embodiment 1, and mainly different points will be described.
In embodiment 2, as shown in fig. 4, an insulating plate 7 is further provided between the battery 2 and the substrate 3, and both sides of the insulating plate 7 are provided with a back adhesive, one side of which is bonded and fixed to the battery 2, and the other side of which is bonded and fixed to the substrate 3.
