Insulation thermique ye mun ye?

Battery fire

O la ko Aricel izini tasuma ye Kore jamana na salon. 23 faga. Ni aw bɛ baara kɛ batiriw la n’a sɔrɔla aw tugura a kɔ kosɛbɛ.

Seli fɔlɔw tɛ Li-ion ye, nka gɛlɛya jɔnjɔn kelen-funteni bɛ bɔ seli kelen na ka tobi nata la, cogo si t’a la k’a bali ni a daminɛna. Depo bɛɛ banna miniti damadɔ kɔnɔ.

Sumaya insulation=fɛnw bɛ seliw ni ɲɔgɔn cɛ walasa k’o sumaya. Tiɲɛ na, o de ye o dɔrɔn de ye.

Not gonna lie, regulatory situation got way more serious after GM tun ka kan ka o Bolts bɛɛ sama ka segin kɔ. Ani Hyundai ni Konas. Sannikɛlaw minnu ma deli ka ɲininkali kɛ thermal management ko la fɔlɔ, olu barika banna ka sɛgɛsɛgɛli rapɔɔriw sɔrɔ, material specs, fɛn bɛɛ.

GB 38031 min bɛ Sinuwa jamana na, o ko i mago bɛ miniti 5 kɔnɔ sani jɛnsɛnni ka se ka selilu kɛrɛfɛtaw gosi. Erɔpu fana bɛ ni o ɲinini suguw ye sisan ECE R100 kɔnɔ. Dimi bɛ kɛ fali la ka seereya kɛ nka n’a sɔrɔla a mago tun bɛ a la.

Insulasi bɛ min kɛ tiɲɛ na

A tɛ thermal bolicogo bali ka kɛ. Foyi tɛ kɛ ni selilɛri y’a latigɛ ka taa. BMS bɛ se ka dɛsɛ cogoya dɔw minɛ joona nka ni kɔnɔna surunya kɛra i bɛ gɛlɛya la kaban.

What insulation actually does

Insulasi bɛ fɛnw sumaya dɔrɔn o kɔfɛ. A bɛ waati san. N’a sɔrɔ BMS bɛ fanga tigɛ sanni seli nata ka taa. N’a sɔrɔ mɔgɔ dɔ ye alarma mɛn ka bɔ forokili la.

A fana bɛ funteni bali ka tasuma don pake so kɔnɔ. Walima fɛnmarayɔrɔ. Ja yelenw minnu bɛ kɛ ni forokili batiri taara so kɔnɔ min falen bɛ kartɔn na. A ma kɛ cɛɲi ye.

Nɛnɛ fɛn fana-insulasi bɛ funteni to a kɔnɔ tuma min na i b’a fɛ tiɲɛ na a ka sumaya. A tɛ se ka Li-ion charge freezing jukɔrɔ k’a sɔrɔ a ma tiɲɛni kɛ. Plating kan anode, seko bɔnɛ banbali. Polinovel ye yɛrɛ-suma-minɛn dɔ labɛn ka segin san 2019 na nin tigitigi in kama. Minɛyɔrɔw sanfɛ worodugu fɛ, nɛnɛ marayɔrɔ, a ɲɔgɔnnaw So funtenifɛn kɔnɔna + insulasi kɛnɛma=pake bɛ to ka sumaya su fɛ.

Fɛn minnu bɛ kɛ ka baara kɛ

Airgel (Aerogel) ye

Bɛɛ bɛ kuma aerogel kan. Ani ɔnhɔn a ka bon-thermal conductivity crazy low, i n'a fɔ 0.02 W/m·K jukɔrɔ. Aspen Aerogels bɛ fɛn ɲumanw dilan.

Musow ka musaka Factor

Cost ye insane ye hali ni o kɛra. I n'a fɔ 5-10x min tun bɛna sara seramiki la. Baara bɛ kɛ Tesla ye laala. A tɛ baara kɛ izini minɛnw na yɔrɔ minnu na marginw ka gɛlɛn.

Fibre Seramiki ye

An fanba bɛ baara kɛ ni min ye tiɲɛ na, o ye seramiki fibre ye. Aluminiyɔmu silikati pankurunw, mullite, fɛn o fɛn. Handles 1000℃+, sira sɔngɔ ka dɔgɔ. Brittle donc i ka kan ka a layer ni polimɛri ye. Morgan b’a dilan, Unifrax, Sinuwa feerekɛlaw kulu.

PCMw (PCMw) ye

PCMw tun bɛ taa ɲɛ waati dɔ kɔnɔ. Fasa caman cili fɛnw-bɛ funteni minɛ ni u wulila. A mankan ka ɲi fo i k’a dɔn ko funteniko lakikaw t’u janto i ka dilancogo miiriliw la. Seli min bɛ PCM kɛrɛ fɛ o bɛ degere 200 na kaban ani ka wuli. An ye ninnu speccing dabila fɛn jugu o fɛn kama.

Fomus réguliers (Fomus) minnu bɛ kɛ tuma bɛɛ

Fomu basigilenw i n’a fɔ PU walima EVA-fine for vibration damping ani gap filling. A tɛ kɛ ka ɲɛsin funteni barika ma. U fanba bɛ tasuma minɛ temps la i bɛna a ye boliway kɔnɔ cogo o cogo.

Random design fɛnw

Busbarw ye. Kupu bɛ wuli ni seliluw sumana ka ɲɛ. Ni i ka -voltage bus ka surun kojugu selilɛriw la i ye sira surun dɔ da dɔrɔn. Seramiki yɔrɔw bɛ dɛmɛ don.

Module (module) bɔgɔlanw. Bɛɛ b'a fɛ max energy density ka sɔrɔ u ka pack tight. O kɔ fɛ, modulu kelen bɛ Taa wa funteni tɛ Se ka Bɔ yɔrɔ min na fo ka Dòn modulu nata la. An bɛ 5-10mm yɔrɔw to ni seramiki felt ye u ni ɲɔgɔn cɛ. A bɛ bɔnɛ density dɔw la, a bɛ lakana margin caman sɔrɔ.

Insulasi janya-segin bɛ dɔgɔya ka tɛmɛ milimɛtɛrɛ 6 ɲɔgɔn kan. Fɛɛrɛba min kɛra 3-6mm cɛ. O kɔ fɛ i bɛ girinya Fàra o kan kosɛbɛ.
