Description

Technical Field

[0001] The invention belongs to the technical field of batteries, and in particular relates to a battery cover. Background Art

[0002] The charging and discharging of lithium battery cells usually requires welding adapters to connect to charging and discharging equipment for charging and discharging, or to charge and discharge with matching equipment and tooling. This is limited by the battery size and the matching of equipment and tooling, which restricts the use of lithium battery cells and the charging and discharging of cells within the module. Summary of the invention

[0003] Purpose of the utility model: In order to solve the problems existing in the above-mentioned prior art, the present invention provides a battery cover.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: This embodiment includes a battery cover, including a substrate, a positive pole base, a negative pole base, and a first and a second connection medium connected to a charging and discharging device; the positive pole base and the negative pole base are both arranged on the substrate, the first connection medium is arranged on the positive pole base, and the second connection medium is arranged on the negative pole base. The present invention connects the battery cover to the lithium battery, and then the positive pole base and the negative pole base can be connected to any form of charging equipment through the connection medium, so that the charging of the lithium battery is not limited by the form of the charging equipment.

[0005] Furthermore, the first and second connecting media are both magnetic attraction media.

[0006] Furthermore, the magnetic attraction medium is a magnetic ring or a magnetic coil.

[0007] Furthermore, the first and second connection media are both card slots.

[0008] Furthermore, the battery cover also includes an explosion-proof valve, which is arranged on the substrate.

[0009] Furthermore, the battery cover also includes a liquid injection hole and a sealing nail. The liquid injection hole is arranged on the substrate, and the sealing nail is inserted into the liquid injection hole.

[0010] Furthermore, the positive electrode column base and the negative electrode column base are both made of metal.

[0011] Beneficial effect: The rechargeable and dischargeable battery using the cover provided by the utility model is not limited by size and equipment and tooling matching, and can be charged and discharged without laser welding connecting pieces or matching equipment and tooling, which improves the convenience of using battery cells and charging or discharging a single cell in the battery module.
