DISCHARGE POWER ALLOCATION ON ELECTRIC POWER MACHINE

Disclosed are power machines having an electric power source which powers a priority system and a non-priority system. A control system determines from a discharge current limit of a battery of the electric power source a priority reserve of discharge current for the priority system, a non-priority reserve of discharge current for the non-priority system, and a pool of discharge current separate from the priority reserve and non-priority reserve. The control system controls the allocation of discharge current to the priority system and to the non-priority system as a function of the priority reserve, the non-priority reserve, and the pool. A control system also determines an inverter temperature scalar, a motor temperature scalar, and a discharge current scalar. Using these scalars, the control system determines a power management scalar which is used to derate power usage by a system such as the priority system.
