A device and a method are provided for interrupting battery current using a latch relay for substantially high current interruption, which enable the latch relay to return to an ON position after operating to an OFF position. Accordingly, the latch relay for substantially high current interruption is operated to return to an ON (closed) position in only a normal state other than a short-circuit state by self-diagnosing the presence of occurrence of a short circuit before the latch relay attempts to return to the ON (closed) position after operating to an OFF (open) position. Therefore the latch relay may not become fixed and damaged due to the returning of the latch relay to the ON (closed) position during a short-circuit state, thereby guaranteeing the reuse of the latch relay.
