Alerts by Status Indicators
CAUTION
Battery modules in a fault 2 state require an inspection by LG Chem. Faulty bat-
tery modules may be recovered and reused unless the cell voltage is less than
2.0 V. Unrecoverable faulty battery modules must be replaced with new ones im-
mediately. If not replaced immediately, faulty battery modules may decrease the
lifespan of the rest battery modules and cause safety problems. Contact LG Chem
or your distributor to order new battery modules for replacement.
1.1.1
Fault 1 states
When a battery module goes into a fault 1 state, the red indicator starts flashing and
the blue indicators show the fault number in binary form.
-
1
The highest cell voltage is higher than the fault 1 level tolerance limit.
2
The lowest cell voltage is lower than the fault 1 level tolerance limit.
3
A current more than the fault 1 level tolerance limit is charged.
4
A current more than the fault 1 level tolerance limit is discharged.
5
A power more than the fault 1 level tolerance limit is charged.
6
A power more than the fault 1 level tolerance limit is discharged.
7
The battery temperature is higher than the fault 1 level tolerance limit.
8
The battery temperature is lower than the fault 1 level tolerance limit.
9
The difference between the highest cell voltage and the lowest is larger than the
tolerance limit.
10
The temperature difference inside the battery module is larger than the tolerance
limit.
11
Communication with other battery modules is lost for longer than the fault 1
level tolerance limit.
