Page 4: Alerts By Status Indicators
Chapter Alerts by Status Indicators The status indicators on the front of a battery module show its operating state. Normal SOC ≥ 75% SOC ≥ 50% SOC ≥ 25% SOC < 25% Voltage imbalance Warning Fault 1 Fault 2 Most problems are identified by the red and blue indicators. If a battery module seems to not work properly but its red indicator neither flashes nor comes on solid, check the fuse of the module. -
Page 5: Fault 1 States
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. -
Page 6: Fault 2 States
Alerts by Status Indicators 1.1.2 Fault 2 states When a battery module goes into a fault 2 state, the red indicator comes on and the blue indicators show the fault number in binary form. The highest cell voltage is higher than the fault 2 level tolerance limit. The lowest cell voltage is lower than the fault 2 level tolerance limit. -

2. Manipulate the higher level system to discharge the ESS with a current less than or equal to 63 A until the highest cell voltage is lower than 4.2 V. 3. Re-activate the ESS when the red indicator turns off. If the problem persists, contact LG Chem for technical assistance. 1.2.2 Cell undervoltage Charge... -

Page 13: Replacements
Chapter Replacements 2.1 Hot-swapping battery modules 2.1.1 Identifying model number To ensure that a new battery module is the same model as the old ones, verify the new module’s model number. 1. Press the On/Off button on the new battery module to activate it. The green indi- cator turns on first and then the rightmost blue indicator turns on a few seconds later. -
Page 14: Checking Fuse
Replacements 1. Holding the button on the connector of the positive cable, pull out the connector to re- move the cable from the module. Remove the negative cable using the same method. 2. Press the On/Off button on the module to deactivate it. -
Page 15: Expanding The Ess
Replacements 4. Slide the right panel to the back to remove it. 5. Remove the fuse cover by pulling it out. 6. Loosen the three nuts that secure the fuse and the negative cable. 7. Pull out the fuse. 8. Measure the resistance of the fuse to see if it is blown. -
Page 16: Reducing The Ess
Replacements 2.4 Reducing the ESS To reduce the ESS by removing some battery modules, follow these steps: 1. Press and hold the On/Off button on the master module for longer than 5 seconds to deactivate the ESS. 2. Shut off the higher level system. 3. -
Page 17: Formulas For Hot-Swapping
Chapter Formulas for Hot-Swapping One battery module can accommodate up to 63 A. If the amount of current that each of the remaining modules has to accommodate exceeds 63 A, hot-swapping is not allowed. The following formula calculates the maximum current per module that allows hot-swapping. - Page 18 Formulas for Hot-Swapping In case of 2 battery modules The maximum current Higher-level system current The number of replaceable during hot-swapping (A) modules In case of 4 battery modules The maximum current Higher-level system current The number of replaceable during hot-swapping (A) modules 43.3 46.7...
