Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery with potting protection. Background Art

[0002] A battery refers to a cup, trough or other container or part of a composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It is a device that can convert chemical energy into electrical energy and has a positive electrode and a negative electrode. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy, such as solar cells. The performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. Using batteries as an energy source can obtain an electric current with stable voltage, stable current, long-term stable power supply, and little external influence.

[0003] However, in the existing technology, high-power and high-rate discharge generally uses high-rate battery cells for discharge, which usually include high-rate aluminum shell battery cells and high-rate soft-pack battery cells. Since high-power discharge occurs, heat generation is of course a top priority. Traditional processes cannot provide a good way to quickly dissipate heat, resulting in major safety hazards and irreversible property losses such as collisions, fires, spontaneous combustion, and explosions.

It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0021] like Figure 1 As shown, multiple battery connecting wires 2 are fixed to one side of the battery shell 1, and the outer side of the multiple battery connecting wires 2 is covered with a covering protective shell 3. The covering protective shell 3 is connected to the battery shell 1 by screws. One end of the battery connecting wire 2 passes through the side of the covering protective shell 3, and the top of the covering protective shell 3 is provided with a pouring hole 6. A connecting tube 4 is installed above the pouring hole 6, and the axis of the pouring hole 6 coincides with the axis of the connecting tube 4. A potting gel 5 is provided between the covering protective shell 3 and the battery shell 1. The potting gel is injected between the covering protective shell 3 and the battery shell 1 through the connecting tube 4 and the pouring hole 6, so that the potting gel 5 is formed after the potting gel solidifies, and the connection between the battery connecting wire 2 and the battery shell 1 is sealed and wrapped.

[0022] As the preferred technical solution of this embodiment, Figure 2 As shown, the potting colloid 5 is a high-strength 1:1 power supply-specific thermal conductive potting glue, which has the characteristics of thermal conductivity, insulation, shockproof, anti-collision, flame retardant, and easy disassembly, and can well conduct the battery heat to the outside world.

[0023] A sealing plug 7 is slidably inserted into the inner side of the top end of the connecting tube 4. The sealing plug 7 is made of rubber and has a diameter consistent with the inner diameter of the connecting tube 4. The connecting tube 4 is sealed by the sealing plug 7 to prevent the potting colloid 5 covering the protective shell 3 and the battery shell 1 from leaking out of the opened connecting tube 4.

[0024] As the preferred technical solution of this embodiment, Figure 3As shown, a plurality of fixing brackets 8 are fixed inside the covering protective shell 3, and connection holes 12 are provided on the upper and lower surfaces of the fixing brackets 8. The connection holes 12 ensure that the potting glue fills the inside of the fixing bracket 8 after pouring, so as to better wrap the battery connection line 2. A wire harness fixing clip 10 is installed on the inner side of the fixing bracket 8. The upper and lower edges of the wire harness fixing clip 10 are slidably inserted into the inside of the fixing bracket 8, and a clamping spring 11 is fixed between the wire harness fixing clip 10 and the fixing bracket 8. The battery connection line 2 is clamped and fixed by the wire harness fixing clip 10, and the upper and lower edges of the clamping spring 11 are squeezed by the wire harness fixing clip 10, so that the battery connection line 2 cannot be easily separated from the wire harness fixing clip 10.

[0025] As the preferred technical solution of this embodiment, Figure 4 As shown, a sealing groove 13 is provided on the surface of the covering protective shell 3 that is attached to the battery shell 1, and a sealing gasket 14 is embedded on the inner side of the sealing groove 13. The inner and outer sides of the sealing gasket 14 are both provided with arc-shaped sealing protrusions 9. The sealing gasket 14 and the arc-shaped sealing protrusion 9 are used to seal the connection gap between the covering protective shell 3 and the battery shell 1 to ensure that the potting glue poured into the covering protective shell 3 and the battery shell 1 will not leak out.

[0026] Working principle: First, pass the end of the battery connecting wire 2 through the side of the covering protective shell 3, and squeeze the part of the battery connecting wire 2 located in the covering protective shell 3 toward the wire harness fixing clip 10 on the inside of the fixing frame 8, so that the battery connecting wire 2 enters the inside of the wire harness fixing clip 10. At this time, the clamping spring 11 squeezes the side of the wire harness fixing clip 10, so that the wire harness fixing clip 10 fits tightly to the outside of the battery connecting wire 2. After all the battery connecting wires 2 are connected to all the wire harness fixing clips 10, the covering protective shell 3 and the battery shell 1 are connected and fixed by screws and the screws are tightened so that the sealing gasket 14 completely enters the inside of the sealing groove 13 and seals the gap between the covering protective shell 3 and the battery shell 1. Finally, the potting glue is passed through The potting glue is poured into the space between the covering protective shell 3 and the battery shell 1 through the connecting tube 4 and the pouring hole 6, so that the potting glue enters the interior of the fixing frame 8 through the connecting hole 12 and completely wraps the battery connecting wire 2. After the potting glue fills the area between the covering protective shell 3 and the battery shell 1, a potting glue 5 is formed. The connection between the battery connecting wire 2 and the battery shell 1 is sealed and wrapped with the potting glue 5, so that the connection between the battery connecting wire 2 and the battery shell 1 is wrapped in the potting glue 5. When high-power discharge is performed, the potting glue 5 will conduct the temperature of the battery connecting wire 2 to the outside of the battery shell 1 in an all-round manner at 360 degrees, so that the battery connecting wire 2 can dissipate heat faster, the battery connecting wire 2 will not be heated, the performance is better, and the risk of spontaneous combustion and explosion caused by high temperature is reduced.
