Performance of Passive and Active Balancing Systems of Lithium Batteries in Onerous Mine Environment

To use lithium-iron-phosphate battery packs in the supply systems of any electric mining equipment and/or machines, the required conditions of work safety must be met. This applies in particular to coal mines endangered by fire and/or explosion. To meet the spark-safety conditions, the cells (togeth...
