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.
No it's not, because that was not a typical lithium battery fire. It looked like all that was burning was the cardboard and wood pallets. Look at other videos of lithium fires. there was no explosive out gassing (rocket engine) no evidence of any cells exploding. I don't think this proves anything except sprinklers put out wood and paper fires.
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!
@@ph11p3540 lipos are not dangerous if you treat them with respect, they will never catch fire unless they are over charged or become physically damaged.
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.
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.
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?
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.
@@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

We have them in our “containment” room. Or what the old-timers say… the boom boom room.
thousands of RC hobbyists gasp in pure horror as lipos are willfully destroyed lol
Amazingly most are not worried that the very batteries they keep are potential incendiary bombs waiting to happen.
@@ph11p3540 lipos are not dangerous if you treat them with respect, they will never catch fire unless they are over charged or become physically damaged.
Exactly lol
@@stevefox3763 not completely true - a small defect in the internal insulators within the battery can cause thermal runaway and a disastrous fire.
@@anslowp1 That is true but exceptionally rare, almost all lipo fires are through damage or improper use/charging.
its a wet system?
Lithium-ion 20 Ah -> how many Wh - or at what voltage??
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?

most likely a blowtorch
This is not a lithium fire!
What is it?
it's not thermal runaway.

Imagine all those batteries in series, like in a ferry!
You're forgetting another thing tho. If one battery burns the sprinkler can prevent a chain reaction by keeping it all cool
Single shot systems like AFFF or CO2 would not work.
Reminds me of that UPS plane that crashed because of these batteries

They’d be liable to over-discharge in transit, which can wreak havoc on battery chemistry and render them D.O.A..
@@forced-to-have-a-handle-fck-g However, all batteries are zero charged soon after manufacture, aren't they?
That's 1989.12KW of batteries, enough to make 50 electric cars (Leafs)!

That graph look like Lyft on the stock market
This is NOT the worse case scenario.... this LOOKS unrealistic, not to say fraudulent
No different from the commodity materials going up in flames. Try this on fully charged batteries and not discharged batteries and see.
When your note 7 and other note 7 explodes
when we mean lithium ion battery fire, we mean THERMAL RUNAWAY (TRA). this is NOT a THERMAL RUNAWAY TRIGGERED FIRE!!!
This is not a lithium battery thermal runaway fire. This is a packaging fire. Try again.
Pee-YEEWW!
water should have caused lithium-ion to burn more violently....
No it shouldn't. Large li ion fires are often treated with water
@@teunlll no you're wrong. look up the science and chemistry...
