DC charging system

Abstract

A direct current charging system is disclosed, configured to charge the battery of a mining, construction, or earthmoving vehicle using an electric power supply. The system comprises one or more power supply units (10) and one or more charging units (20). Each power supply unit (10) is configured to receive power from an external source and to transmit the converted power to at least one charging unit (20). Each charging unit (20) is configured to receive converted power from at least one power supply unit (10) and transmit charging power to the battery of a mining, construction or earthmoving vehicle powered by electricity. Each power supply unit (10) has at least one first docking side (15a, 15b), and each charging unit (20) has at least one second docking side (25a, 25b), which are designed with the possibility of docking / mating with each other in such a way that when arranged side by side, said at least one power supply unit (10) and said at least one charging unit (20) form a single spatially limited unit (100).
