Samsung patents power manager that stops devices from overloading circuits

1. A master electronic apparatus comprising: a communication interface; and a processor configured to: receive, through the communication interface, first data regarding predicted power consumption amounts for respective tasks of a first electronic apparatus and second data regarding predicted power consumption amounts for respective tasks of a second electronic apparatus which are expected to be newly performed, calculate summed-up values of the predicted power consumption amounts for respective times based on the first data and the second data, and compare the summed-up values with instantaneous power amount limits for the respective times which are maximum power amounts allowed to be consumed in the respective times, control the communication interface to transmit, based on the summed-up values being smaller than the instantaneous power amount limits in entire times, a task approval signal to the second electronic apparatus through the communication interface, and control the communication interface to transmit, based on identifying a time wherein a summed-up value is greater than or equal to an instantaneous power amount limit, at least one of: a control signal to change a type of a task of the first electronic apparatus expected to be performed in the identified time, a control signal to delay the task of the first electronic apparatus, or a control signal to disapprove a task of the second electronic apparatus expected to be performed in the identified time, to at least one of the first electronic apparatus and the second electronic apparatus based on priorities, so to, for the identified time, adjust the summed-up value that is greater than or equal to the instantaneous power amount limit, to be less than the instantaneous power amount limit of the identified time, by at least one of changing the type of the task of the first electronic apparatus expected to be performed in the identified time, delaying the task of the first electronic apparatus, or disapproving the task of the second electronic apparatus expected to be performed in the identified time.
