KStar E10KT - Emergency Procedure

3.3.1 Emergency Handling Plan
3.3.2 Hazards
There may be a possible explosion when batteries are heated above 150°C.
When the battery pack is burning, it leaks poisonous gases. Do not approach.
When the E8KT/E10KT/E12KT energy storage system appears to be running abnormally, you can
turn off the grid-connected main switch that 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.
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 can analyse and solve theCompany
fault. Any operation of equipment during a fault is strictly forbidden, please contact Company
as soon as possible.
4.As battery cells contain 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.
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.
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.
Effective ways to deal with accidents
Battery in dry environment: Place damaged battery into a segregated place and call local fire
department or service engineer.
Battery in wet environment: Stay out of the water and don’ t touch anything if any part
of the battery, inverter, or wiring is submerged.
Do not use a submerged battery again and contact the service engineer.
