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.

    本公开涉及用于纯电动挖掘机的能量管理方法及相关装置。一种用于纯电动挖掘机的能量管理方法,包括:根据纯电动挖掘机的多个系统中的每个系统的重要性,确定多个系统的功率分配优先级;根据纯电动挖掘机的电池的实际可输出功率、多个系统中的每个系统的功率分配优先级及其请求功率,确定多个系统中的每个系统的可用功率,其中,响应于电池的实际可输出功率大于多个系统中高于指定功率分配优先级的系统的请求功率之和并且不大于多个系统中不低于指定功率分配优先级的系统的请求功率之和,确定指定功率分配优先级的系统的可用功率为电池的实际可输出功率与多个系统中高于指定功率分配优先级的系统的请求功率之和的差值。
