6 FAQs about [Explosion-proof laser battery line for coal mines]

What is the explosion-proof protection of Lib?

Can lithium battery pack be used in underground coal mining?

In coal mining industry, specifically in underground coal mining, the requirements on lithium battery pack applications are very stringent with various engineering constraints imposed on them, which, in most cases, make the application of lithium technology in such an environment unfeasible or impractical.

Can a LFP battery cause a secondary explosion?

It is verified that the LFP battery will not cause a secondary explosion even under the condition of a high concentration of CH 4 after thermal runaway; however, the release of gas could potentially lead to excessive pressure in the explosion-proof shell and further cause catastrophic events.

What are the different types of explosion-proof protection technologies for Lib vehicles?

There are three explosion-proof protection technologies for LIB vehicles: Explosion-proof (Ex’d’), intrinsically safe (‘ia’/’ib’) and encapsulation (Ex ‘ma’/’mb’). At the same time, the increased safety type (Ex ‘e’) or the combination of several protection technologies may also be considered to achieve the required protection level.

What temperature does coal dust accumulate in a battery?

During coal mining or processing, coal dust accumulates into the explosion-proof shell of the battery. MSHA [ 106] requires that the outer surface temperature of the explosion-proof shell shall not exceed 150 °C. The ignition temperature of the coal dust cloud is 440 °C to 640 °C.

What is explosion-proof design for Lib vehicles?

The explosion-proof design must be adopted, and the internal pressure of the explosion-proof container must meet the static pressure of 1 MPa. There are three explosion-proof protection technologies for LIB vehicles: Explosion-proof (Ex’d’), intrinsically safe (‘ia’/’ib’) and encapsulation (Ex ‘ma’/’mb’).
