3.3 Emergency Procedure
When the SMILE5 energy storage system appears to be running abnormally you can turn off the grid
connected main switch directly feeding the BESS and turn off all load switches within the BESS, turn
off the battery switch at the same time. To prevent a potentially fatal personal injury, if you want to
repair or open the machine after the power is switched off please measure the voltage at the input
terminals with a suitably calibrated voltage tester.
Before working on this equipment, please confirm that there is no grid electric supply to the BESS!
The upper cover plate cannot be opened until the DC-link capacitance inside the battery modules
discharges completely about 15 minutes later.
3.3.1 Emergency Handling Plan
1. Disconnect the AC breaker.
2. Check the control power supply. If it is OK, return the power supply to find out the reason.
3. Please record every detail related to the fault, so AlphaESS can analyse and solve the fault. Any
operation of equipment during a fault is strictly forbidden, please contact Alpha as soon as possible.
4. As battery cells contains a little Oxygen inside and all cells have got explosion-proof valves,
explosion hardly happens.
5. When the indicator light on the battery shows a red fault, check the fault type through the
communication protocol, and contact our after-sales service personnel for advice.
3.3.2 Hazards
If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas. If one is exposed to
the leaked substance, immediately perform the actions described below:
Inhalation: Evacuate the contaminated area, and seek medical attention.
Eye contact: Rinse eyes with running water for 5 minutes, and seek medical attention.
Contact with skin: Wash the affected area thoroughly with soap and water, and seek medical attention.
Ingestion: Induce vomiting and seek medical attention.
3.3.3 Fire
If a fire breaks out in the place where the battery pack is installed, perform the following
countermeasures:
Fire extinguishing media
During normal operation no respirator is required. Burning batteries can not be extinguished with a
regular fire extinguisher, this requires special fire extinguishers such as the Novec 1230, the FM-200
or a dioxin extinguisher. If the fire is not from a battery, normal ABC fire extinguishers can be used for
extinguishing.
