1. A battery system comprising:
at least one battery pack;
at least one processor; and
memory storing instructions that, when executed by the at least one processor, cause the battery system to:
control a first apparatus, causing the first apparatus to transmit a battery discharge mode command and a motor command;
control a second apparatus, causing the second apparatus to:
transmit a relay control command based on receiving the battery discharge mode command; and
transmit a diagnosis command based on receiving the motor command;
control at least one third apparatus, causing the third apparatus to:
control a relay associated with the relay control command and supply a current of a battery pack of the at least one battery pack to a motor based on receiving the relay control command;
measure the current of the battery pack based on receiving the diagnosis command; and
determine that the battery pack is in a faulty state based on the measured current not exceeding a predetermined threshold value, and
control a ground control circuit, causing the ground control circuit to output, based on receiving a notification of a battery pack failure state from the first apparatus, the notification.
