BATTERY MANAGEMENT SYSTEM FOR WELDING POWER SOURCE POWERED BY DETACHABLE BATTERY PACKS

Abstract: a method performed by a welding system configured to be powered by a battery to generate weld power to strike an arc for a welding or a plasma cutting operation includes: receiving a selection of a welding mode among different welding modes in which the welding system is capable of operating, to produce a selected welding mode; determining, for the selected welding mode, an energy consumption requirement that depends on the selected welding mode; determining a state of charge (soc) of the battery and a battery energy from the soc; determining a remaining amount of welding or plasma cutting that is supported by the battery energy based on the battery energy and the energy consumption requirement; and presenting an indication of the remaining amount for the selected welding mode.
