The invention relates to an energy management method for a pure electric excavator and a related device. An energy management method for a pure electric excavator comprises the steps that according to the importance of each system in multiple systems of the pure electric excavator, the power distribution priorities of the multiple systems are determined; according to the actual output power of a battery of the pure electric excavator, the power distribution priority of each system in the multiple systems and the request power of the power distribution priority, the available power of each system in the multiple systems is determined, responding to the fact that the actual output power of the battery is larger than the sum of the request power of the systems higher than the specified power distribution priority in the multiple systems and is not larger than the sum of the request power of the systems not lower than the specified power distribution priority in the multiple systems; and determining that the available power of the system with the specified power distribution priority is a difference value between the actual output power of the battery and the sum of the requested power of the systems higher than the specified power distribution priority in the plurality of systems.
