DANGER!
Batteries present an inherent risk of electrical shock. Contact with any part of the battery circuit
battery can result in electrical shock.
Batteries are supplied in a charged condition and are capable of extremely high short circuit currents.
Take care to avoid short-circuiting any terminals; use only appropriately insulated tools.
Warning: Risk of fire, explosion, or burns. Do not disassemble, heat above 60ºC, or incinerate. Avoid
any short circuit. Avoid any Metallic parts around the battery, do not place tools or items on top of the
battery.
The following additional precautions must be observed when working on batteries:
1. Remove watches, rings, or other metal objects from your person.
2. Use insulated tools only.
3. Wear insulated gloves and electrically insulated boots.
4. Do not lay tools or metal parts on top of batteries.
5. Ensure that the battery disconnect switch is open prior to installing or maintaining the battery.
6. Do not use any type of oil, solvent, detergent, petroleum-based solvent or ammonia solution to clean the battery
containers or lids. These materials will cause permanent damage to the battery container and lid and will invalidate
the warranty.
Follow the suggested maintenance schedule required for batteries as described in section 1.2. For servicing of battery
modules from the cabinet, contact Socomec.
WARNING!
Check to ensure environmental safety, system safety, no alarm, no fault before performing
maintenance operations.
After the battery maintenance of ESS is completed, you can notify our after-sales engineer to perform
data analysis for free.
Plan 1 (This plan is applicable when SOC of the battery system is from 10%~20%SOC)
1. Discharge the battery system to the cut-off condition (Average cell voltage< 3.1V or the lowest voltage<2.), then
stop discharging, standing for 1 hour.
2. Fully charge the battery system (The highest voltage>3.65V), after charging, let stand for 1 hour.
3.
Discharge the battery system to 40% SOC and stop
Plan 2 (This plan is applicable when SOC of the battery system is 60~90%SOC)
1. Fully charge to the battery system (The highest voltage>3.65V), after charging, let stand for 1 hour.
2. Discharge the battery system to the cut-off condition (Average cell voltage< 3.1V or the lowest voltage<2.8V), then
stop discharging, standing for 1 hour.
3.
Charge the battery system to 40% and stop
