  • Device and method for controlling power according to a load of a hybrid excavator
    Patent number: 9071054
    Abstract: A power control apparatus and method according to a load of a hybrid excavator including an H-ECU is disclosed. If a difference between an actual power value actually used in a load (SW PEC and ISAM PEC) or in an ESS and a power value required for an actual use in the load is equal to or larger than a set error value, a power that is supplied from the ESS to the PECs and a power that is supplied between the PECs are controlled to be cut off, and thus high voltage is prevented from being continuously supplied to circuits to thereby prevent secondary problems (e.g., fire, trouble of equipment, and the like) from occurring due to the high voltage.
