Abstract:
1. An energy management apparatus that manages energy consumed in a machine having a supply part that supplies an energy and a plurality of consume parts that consume the energy supplied by the supply part, each consume part of the plurality of consume parts having an input energy sensor and an output energy sensor, said energy management apparatus comprising: an operating part that operates the plurality of consume parts by using the energy supplied by said supply part; an acquisition part that acquires, for each of the plurality of consume parts, an energy conversion characteristic, as an energy efficiency, from the input energy sensor detecting an input energy supplied to each consume part and the output energy sensor detecting an output energy output from each consume part, the energy efficiency of each consume part being calculated by dividing a detection value of the output energy sensor by a detection value of the input energy sensor; a target state determination part that determines a target state based on the energy efficiency and an achievement of an operation request to generate a determination result; a change part that changes an operating condition of each consume part based on the energy efficiency and the determination result so as to improve an actual value of the energy efficiency; a determination part that determines that an energy transmission system of said machine is abnormal when the energy efficiency of at least one of the plurality of consume parts is equal to or smaller than a specified value; and a specified value change part included as part of the change part that changes the specified value of the energy efficiency into the actual value of the energy efficiency when the actual value of the energy efficiency is larger than the specified value of the energy efficiency.
