Abstract

The invention relates to a mining vehicle and method for its energy supply. The mining vehicle (1) has a rectifier (27), DC intermediate circuit (28), and inverter (29a, 29b, 29c), through which an alternating current motor (30a, 30b, 30c) is supplied. At least one auxiliary energy source (26a, 26b) is connected to the DC intermediate circuit (28). A DC / DC converter (33a, 33b) is connected between the DC intermediate circuit (28) and the auxiliary energy source (26a, 26b) for adapting the voltage level of the auxiliary energy source (26a, 26b) and for connecting the auxiliary energy source (26a, 26b) to supply energy to the DC intermediate circuit (28).
