Embodiment 1

[0057] Embodiment 1 As shown in Fig. 1, Fig. 2 and Fig. 3, with 20 capacity 2200mAh, diameter is about 18mm, the lithium ion battery 1 of height is about 65mm is monomer, uses glass fiber 2 (Du Pont product, trade name Nomex ) around the battery rolling groove one by one, use a mold to cover the battery head tightly, pour epoxy resin 3 as shown in Figure 2, heat and cure at 45°C, and assemble into a 3.6V 116.6Ah lithium-ion battery pack. The epoxy resin used is Jeffco3176, its softening point HDT is 195F (ASTM D648-264) (about 90°C). In the way of filament wound battery, as shown in FIG. 1 , the glass fiber wire 2 extends outward with the equilateral triangle formed by three single batteries 1 as the basic unit. Finally, the single cells 1 can be connected with the conductive connecting piece 4 (as shown in FIG. 4 ).

[0058] In Example 2, 53 lithium-ion batteries with a capacity of 2200mAh, a diameter of about 18mm, and a height of about 65mm were used as monomers to form a ...

Embodiment 3

[0059] Example 3 As shown in Figure 3, 20 lithium-ion batteries with a capacity of 3000mAh, a diameter of about 27mm, and a height of about 65mm are used as monomers to form a 3.6V / 60Ah lithium-ion battery pack in the same way as in Example 1. .

Embodiment 4

[0060] Example 4 As shown in Figure 4, 60 lithium-ion batteries with a capacity of 3.0Ah, a diameter of about 26mm, and a height of about 70mm are used as monomers to form a 10.8V / 60Ah lithium-ion battery in the same way as in Example 1. Group.

[0061] The above four battery packs were tested according to the vibration resistance test method of the electric vehicle battery mentioned above, and all of them met the standard requirements.

[0062] The above-mentioned embodiments 1 to 4 used lithium-ion battery cells, but the storage battery pack and its manufacturing method of the present invention are not limited to the use of lithium-ion batteries, and the effects of the present invention can also be obtained by using nickel-metal hydride batteries or other storage batteries. The shape of the battery is not limited to the cylindrical shape, and the effect of the present invention can also be obtained by adopting this method for batteries of square, rhombus or other shapes.

Abstract

The invention is concerned with storage battery fortified by glass fiber reinforced resin and production. Each single battery connects with others by conductive connecting piece and they are reinforced by resin composites. The resin composite contains reinforced material being one or some of glass fiber, carbon fiber, aramid fiber or PVA fibers with super-large molecular weight. The resin material for reinforcing is thermoset resin containing epoxy resin, unsaturated polyester resin, phenolic resin or vinyl ester resin. Wind each battery with fiber and cover the top of battery with module, pour with thermoset resin and heat to solidify and connect each single battery with conductive connecting piece. The battery has better capability to bear vibration, speedup and impaction to solve a problem for security and low cost to battery.

Description

technical field [0001] The present invention relates to a reinforced battery pack and its manufacturing method, in particular, to a glass fiber reinforced resin reinforced battery pack and its manufacturing method. Background technique [0002] With the development of various portable and mobile electrical equipment (mobile communication equipment, portable office equipment, power tools, electric vehicles, etc.), the demand for various battery packs is endless. From the perspective of environmental protection and energy saving, the development of clean and pollution-free electric vehicles has become a breakthrough in the automobile industry of various countries. Electric vehicles have incomparable advantages over traditional fuel vehicles, such as: low noise, 97% reduction in pollutant emissions, diversified energy sources, and high energy efficiency. The energy utilization rate of electric vehicles is 17.8%, while the energy utilization rate of fuel vehicles is only As 10....
