TEST VIDEO (2 of 2): Large-scale Sprinklered Fire Test of Lithium-ion 20 Ah Polymer Pouch Batteries
FM Global has conducted research on lithium-ion batteries in an industry collaboration with the Property Insurance Research Group through the National Fire Protection Association's (NFPA) Fire Protection Research Foundation. All testing was conducted at the FM Global Research Campus in Rhode Island, USA 2015 and 2016.
Lithium-ion 20 Ah Polymer Pouch Batteries: This large-scale fire test was conducted to determine ceiling sprinkler protection guidance for storage of lithium-ion batteries in a warehouse setting. The test array represents rack storage of 15 ft high under a 40 ft high ceiling and contains 26,880 batteries (24 pallet loads). The successful performance of the sprinkler system has confirmed a sprinkler protection design that can be applied to a range of lithium-ion batteries in bulk storage.

A great validation of sprinkler effectiveness on an external fire. It would be interesting to see how effective the same system would if the fire started from a cell internal short, where the heat rise starts within the packaging, rather than outside it.

@tomfenimore9667 5 жыл бұрын

Looks like packaging and external cell material burned and was contained. It would be a much different story if the cell was ignited internally as Nicholas suggested. The cells in this example were idle (room temp) and had little time to heat up and explode/discharge in this test. Energy storage systems will heat up from the inside, not the outside. They are typically located in remote areas near substations and wind/solar farms etc. So external heating is really a very small threat.

Maybe those shelves should have sprinklers too? In many Nordic countries they are mandatory if shelving is considered a solid (fire code). Very useful and interesting experiment! Big thumps up for FM Global for doing this!

Lithium-ion 20 Ah -> how many Wh - or at what voltage??

@jasonbrown467 Жыл бұрын

i would like to know how the fire was started. dead short? over charge? too high of voltage? oe something else what was close to the battery? what was the state of charge at the time of the fire? i use 32 22ah lipo cells for my ebike, and to replace them would be about $3000. i would hate to see how much money was spent on this test.

This was a bad test. Batteries are charged to 3.7V for storage. This is only 50% of energy. A lot of carton and other passive materials are present, to perform a real test he can use a Tesla battery pack or electric bus battery, do several overcharge to start a fire.

The problem is not realized here with Lithium-ion batteries. Sure, in a small quantity they can be managed with traditional methods. Cut the heat, cut the O2, blah blah. Break one link in the fire tetrahedral. This special application needs a 2 fold solution: Contain the source as quickly as possible, ie: AFFF, then continuous cooling via C02 at intelligent intervals via a pumped system from under the source. An FM-200 agent could supplement the process, but only if regulated over time and not 100% dumped. The Aqueus layer would also need a elastimer to sustain pressure differentials . Just a thought. Isolated Wi-Fi modules could help in a stacking scenario for early detection as well.

You're forgetting another thing tho. If one battery burns the sprinkler can prevent a chain reaction by keeping it all cool

Seems to me that all rechargeable batteries should be bulk shipped in a low charge state. That would eliminate much of the energy required to drive a full-blown conflagration. Seems painfully obvious to me, but then, what do I know?

@@cc950 So I guess you can explain me how I am wrong. I work with li ion every day. You are talking about lithium metal primary batteries. Lithium ion responds differently and can be extinguished with water. Alot of Battery manufactories actually suggest to extinguish with water as li ion batteries contain very little lithium metal, which actually responds with water. If you want to do actual research you should look at battery university. batteryuniversity.com/learn/article/safety_concerns_with_li_ion
