Electric power distribution system and method for electric mining machine

A power control system in an electric mining machine for providing electric power distribution, the power control system comprising:

• a power system controller in communication with at least a first battery pack and a second battery pack of an electric mining machine;
• the first battery pack configured to supply electric power to a front electric motor to drive a front axle of the electric mining machine;
• the second battery pack configured to supply electric power to a rear electric motor to drive a rear axle of the electric mining machine;
• and
• wherein the power system controller is configured to:
• compare a state of charge of the first battery pack to a state of charge of the second battery pack;
• and
• upon determining that (1) the electric mining machine is under load, and (2) the state of charge of the second battery pack is greater than the state of charge of the first battery pack, increase electric power to the rear electric motor of the electric mining machine to accommodate the load, wherein the load is associated with at least one of hauling material or climbing an inclined surface.
