Control method of laundry treatment apparatus

A laundry treatment apparatus, comprising:

• a first treatment device having a first load unit for treating laundry;
• a second treatment device having a second load unit for treating laundry;
• and
• an electric power control device that is connected to a power supply and that is configured to supply electric power to the first treatment device and the second treatment device, comprises at least one processor,
• wherein the at least one processor is configured to:
• supply electric power to the first load unit to execute a first cycle set in the first treatment device;
• supply electric power to the second load unit to execute a second cycle set in the second treatment device, the second cycle being executed during execution of the first cycle;
• when an amount of current per unit time that is supplied to the laundry treatment apparatus is equal to or greater than a predetermined reference current amount, control the second treatment device to terminate the second cycle and execute a third cycle so as to consume a lower amount of current than an amount of current per unit time necessary to execute the second cycle;
• control the first treatment device to terminate the first cycle;
• and
• control the second treatment device to re-execute the second cycle after terminating the first cycle, and
• wherein the at least one processor is further configured to:
• control the second treatment device to terminate the third cycle and re-executethe second cycle after terminating the first cycle, if the first cycle is a cycle for heating water to treat the laundry;
• and
• determine whether to re-execute the second cycle of the second treatment device based on an execution time at which the second cycle and the third cycle were executed in the second treatment device, if the first cycle is a cycle for supplying heated air to treat the laundry.
