This is probably because, if no power is actually consumed from the battery, for example, an unstable behavior in the motor for traveling does not occur. For this reason, the system main relay is shut off when a predetermined time has elapsed. In addition, if the current value in the high-voltage circuit is not less than the predetermined threshold value, unstable motor behavior may occur because power is consumed from the battery. For this reason, the system main relay is shut off even if the high voltage shutoff acknowledge signal is not received from the equipment using the high voltage system.
