6 FAQs about [Battery charging for coal mines]

How does a battery system work in underground mining?

This governs the power output. They can then combine these strings in parallel to build the required energy storage capacity and provide the required duration. The heavy loads at play in underground mining mean that vehicles need to deliver high power. That calls for battery systems rated at 650-850V.

Can battery-powered mining vehicles be used in underground mining?

There are several battery and charging technologies which need to be considered when transitioning to electromobility in underground mining. Battery-powered mining vehicles are ideally suited for underground mining.

Can battery powered vehicles decarbonize mines?

That is creating more interest in decarbonizing mines. Load, haul, and dump (LHD) machines are an excellent opportunity to do this. They represent around 80% of the energy demand for underground mining as they move people and equipment through the mine. Switching to battery powered vehicles can decarbonize mining and simplify ventilation systems.

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 voltage should a car battery be rated for underground mining?

The heavy loads at play in underground mining mean that vehicles need to deliver high power. That calls for battery systems rated at 650-850V. While uprating to higher voltages would provide higher power, it would also lead to higher system costs, so it is believed systems will remain below 1,000V for the foreseeable future. Saft

How does nickel affect NCM battery performance?

With the increase in the proportion of nickel, the specific energy of the NCM battery increases, accordingly; with the increase in the proportion of cobalt, the battery performance is more stable; with the increase in the proportion of manganese, the output voltage of the battery increases accordingly [ 30, 31, 32, 33 ].
