6 FAQs about [The coal mine explosion-proof battery system consists of]
What is the lithium-ion battery management system for explosion-proof mining electric vehicle?
This paper designs a kind of lithium-ion battery management system for explosion-proof mining electric vehicle according to GB3836-20210 series standard. And the management system takes STM32F103 as the main controller and LTC6811 as the core, using passive equalization strategy to realize battery voltage equalization.
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 lithium batteries be used in mining?
The mining industry has encountered difficulties in deploying large LIB packs (more than 100 kWh) for the underground coal environment, and currently, most battery applications are only in low-power devices with currents drawn in the milli-amperes range .
How much heat does a battery pack generate?
The battery pack thermal runaway simulation had the same total heat generation as the single cell simulation performed in the last section, with a constant heat generation rate of 1.354 × 10 7 W/m 3. From the experimental data, however, the heat generation rate of the battery pack was slower than that of the single battery simulation.
What are explosion-protection techniques?
Explosion-protection techniques (also called type of protection or explosion-protected apparatus) are classed under a generic term, which describes the use of particular techniques for constructing electrical apparatus for use in hazardous areas .
Can Li-ion battery thermal runaway protection be encapsulated?
An encapsulated method is proposed for largescale Li-ion battery thermal runaway protection. A series of nail penetration experiment are conducted for thermal abuse analysis. Data-intensive modeling is designed for single and 10 cell pack thermal abuse simulation.
