Abstract

The invention belongs to the technical field of lithium batteries, and discloses an intrinsic safety type explosion-proof battery which comprises a battery body, a battery positive port and a battery negative port, the battery body is connected with the battery positive port through a first wire, and the battery body is connected with the battery negative port through a second wire; a three-stage power supply and current limiting circuit is also arranged between the first wire and the second wire, and the three-stage power supply and current limiting circuit comprises a first-stage power supply and current limiting circuit, a second-stage power supply and current limiting circuit and a third-stage power supply and current limiting circuit; and the first-stage power supply and current limiting circuit, the second-stage power supply and current limiting circuit and the third-stage power supply and current limiting circuit are used for limiting the discharge time and discharge current of the battery body. The explosion-proof battery has the beneficial effects that the three-stage current limiting and power supply circuit is designed in the explosion-proof battery, so that the current of the battery can be effectively limited, ignition sparks caused by severe fluctuation of the current are avoided, and the safety of the battery is improved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to an intrinsically safe explosion-proof battery. Background technique [0002] At present, the application range of lithium batteries is more and more extensive, and various battery types have been developed. For a specific working environment, it is necessary to carry out corresponding safety design for the battery. [0003] When the battery works in a specific hazardous area, such as a mine, a workshop with dust or a chemical workshop, a high-level safety design should be carried out to ensure safe use. In hazardous environments, battery sparks should be avoided. Although protective measures are designed in the prior art, the generation of electric sparks cannot be completely avoided, and potential safety hazards still exist. Contents of the invention [0004] The purpose of the present invention is to provide an intrinsically safe explosion-proof battery, which ha...
