Abstract: A mobile charging station for charging a vehicle in an underground mine is provided. The mobile charging station includes an electric input configured to receive an input voltage from an electrical network of a mine, at least one output configured to charge a battery of the vehicle connected to the output, a charging circuitry configured to provide electric power to the at least one output, and a voltage transformer arranged between the electric input and the charging circuitry, the voltage transformer being configured to transform the input voltage received via the electric input to a configured output voltage for the charging circuitry.

Abstract: A charging apparatus includes one or more charging ports and monitors incoming voltage. If the charging apparatus detects a decrease in the incoming voltage it limits charging power in a charging port. If there are several active charging ports a priority configuration can be used for prioritizing different charging ports.
