Ok donc n terikɛ Mike y'a ɲini n fɛ n ka fɛn dɔ sɛbɛn lithium battery technology kan a ka bulɔgu kan ani im like sure mun na a ma kɛ. Been messing with ce things since 2019 tuma min na ne ye nin cheap chinois power bank san min ye tasuma minɛ tiɲɛ na ne ka kɔfɛbagan na (a janya maana, ill get to that)
O la hali nin fɛɛrɛ in ye mun ye .
Lithium batiriw... u basigilen bɛ faraw dɔrɔn de kan minnu bɛ kuran mara? lol ok tɛ tiɲɛ ye nka suguya dɔ. Simi yɛrɛ ye litiyamu ionw ye minnu bɛ yaala-yaala batiri kɔnɔ fan fila cɛ - anɔdi ni katodi (ne bɛ ɲinɛ tuma bɛɛ min kɔ min ye tiɲɛ ye).
N'i y'a charge (sara) ionw bɛ Taa sira kelen fɛ, n'i y'a Kɛ u bɛ Segin. A bɛ i n’a fɔ metoro fitinin dɔ atomu walima fɛn wɛrɛ kama. N terikɛ Sarah min ye doktora sɔrɔ chimie la, o y’a ɲini k’a ɲɛfɔ n ye siɲɛ kelen dɔlɔminnan dɔ la ani n tun ye dɔlɔminna ye kojugu fo n ma se k’a fanba hakili to a la nka thats the gist.
Fɛn min nafa ka bon tiɲɛ na - ani nin ye san caman ta ka jateminɛ kɛ - ye ko litiyɔmu batiriw bɛɛ tɛ kelen ye. Theres regular lithium ion (i n'a fɔ i ka iPhone), o kɔfɛ theres lifepo4 min ye lithium nɛgɛ fosifate ye, ani kulu wɛrɛw kulu dɔ ni kobalt walima manganɛsi walima fɛn o fɛn.
n ye fanga banki min kofɔ ka tɛmɛ .
So yeah, 2019. Ne ye nin 20000Mah Power Bank san ka bɔ AliExpress na ni $15 ye. A tun bɛ iko a ka ɲi kosɛbɛ wa?? hakɛ.
N tun bɛ sira taama dɔ la ka tɛmɛ Arizona (jatigɛ jugu btw, a ka funteni kosɛbɛ yen zuluyekalo la) ani Power Bank tun bɛ n ka kɔfɛbagan na kɔfɛsigilan na. A seginna mobili la taama kɔfɛ ani sisi tun bɛ bɔ n ka bɔrɔ kɔnɔ. Power Bank tun fununa i n’a fɔ balon ani a tun bɛ ka nin mankan mankan bɔ.
siranna ka bɔ ne la. A ye kɔfɛbaga bɛɛ fili mobili kɔnɔ ka a makɔnɔ a ka... I dont know, explode? A ma pɛrɛn nka a ye n ka fɛn dɔw wuli sisan. A ye tile ɲɛjibɔlan ɲuman dɔ tunun o don. KA FARA.
Anyway thats when I daminɛna tiɲɛ na ka ɲinini kɛ nin fɛn in kan sanni ka fɛn o fɛn san dɔrɔn a sɔngɔ ka dɔgɔ Amazon kan.
Mun na chimie nafa ka bon tiɲɛ na (hali tho its boring) .
Litiyɔmu batiri suguya wɛrɛw ka faratiw tɛ kelen ye. I n’a fɔ o fanga banki min tun bɛ ne bolo wa? N’a sɔrɔ a tun bɛ ni litiyɔmu cobalt ɔkisizɛni selilɛriw ye tuma bɛɛ. Olu ka ɲi kosɛbɛ fanga density - i bɛ fanga caman sɔrɔ yɔrɔ fitinin dɔ la - nka u fana bɛ se ka taa thermal runaway.
Sumaya boli ye ni batiri bɛ daminɛ ka sumaya ani a bɛ se ka jɔ a yɛrɛ la. A bɛ sumaya ka taa a fɛ fo a ka tasuma minɛ walima a bɛ bɔn walima u fila bɛɛ. Ɲɛnajɛ waatiw.
Batiri litiyɔmu nɛgɛma (LifePo4) batiriw bɛ sabati kosɛbɛ. A ka chimie ye dɔrɔn... less reactive? Fɛn dɔ bɛ nɛgɛ fositɛri la ka sabati funteni caman na. I dont remember the exact reason nka ive ma deli ka tasuma minɛ min bɛ ka minɛ.
Jiginni ye u ka bonya ani u ka girinya o seko kelen na. Fana jigin voltage - i n'a fɔ 3.2V seli kelen na sanni 3.7V. Doesnt mankan ka ca nka a bɛ fara ɲɔgɔn kan.
random stuff mɔgɔ si b'a fɔ i ye .
Funteni ka bon kosɛbɛ. I n’a fɔ massive. Ne sigilen bɛ Minnesota sisan ani nɛnɛ waati la ne ka kuran nɛgɛso batiri bɛ tunun i n’a fɔ 30% a ka fɛnw na ni a bɛ duguma. A tɛ kɛ bawo seko bɛ dɔgɔya (a ɲɛ bɛ cogo min na) nka bawo chimie bɛ sumaya dɔrɔn ni a nɛnɛna.
Samiya la a ka gɛlɛya kɔfɛ. Aw bɛ batiri to aw ka mobili kɔnɔ ni a ka degere 95 bɔra? Youre degrading a. N’a sɔrɔ o tɛ caman ye, nka a bɛ fara ɲɔgɔn kan waati tɛmɛnen kɔ.
Fana - ani nin ye fɛn ye min bɛ n sɛgɛn dilanbagaw ko la - u ka "cycle life" u bɛ min laseli kɛ o ye BS dafalen ye. U bɛ o batiriw kɔrɔbɔ cogo dafalen na i n’a fɔ degere 20-25, chargement ani discharge ni hakɛ kɛrɛnkɛrɛnnenw ye, u tɛ taa abada 20% duguma walima ka tɛmɛ 80% kan.
Ɲɛnamaya yɛrɛ kɔnɔ wa? Mɔgɔ si tɛ baara kɛ ni batiriw ye o cogo la. I bɛ charge kɛ 100%, ka baara kɛ n’a ye fo a ka sa, laala a bɛ a to a sigilen ka sa dɔgɔkun kelen sanni a ka chargement kɛ tugun. O bɛ batiriw faga teliya la ka tɛmɛ baarakɛcogo "ɲuman" kan.
Jackery Power Station dɔ tun bɛ n bolo min tun bɛ jate 500 ye. A ye n sɔrɔ n’a sɔrɔ 300 sanni a ka juguya ka juguya. Hali bi a bɛ baara kɛ nka siga t’a la ko ne ye min sara.
yɔrɔ min na i bɛ o fɛnw ye tiɲɛ na .
EVS .- A jɛlen don. Teslas, Rivians, kuran mɔbili kura bɛɛ. Tesla ye tiɲɛ na u ka standard range mobili kulu dɔ wuli ka taa Lifepo4 batiriw la bawo u sɔngɔ ka dɔgɔ ani u bɛ mɛn. A bɛ kɛ ni hakilina ye mobili dɔ kama i bɛ se ka min mara 10+ sanw na.
A jigincogo ka dɔgɔ dɔɔnin nka tiɲɛ na min b’a janto a la. Mɔgɔ fanba tɛ boli 300+ kilomɛtɛrɛ tile kelen cogo o cogo.
Solar fɛnw .- Nin yɔrɔ in de la ne donna a kɔnɔ fɔlɔ. A tun b’a fɛ ka off-Grid sigicogo dɔ jɔ ne ka kabini (dont have the cabin yet n’a ma kɛ im planning ye). Litiyɔmu batiriw ka fisa ni plɔmu kɔrɔ ye-acide batiriw bɛɛ tun bɛ baara kɛ ni minnu ye.
Asidi plɔmu batiriw bɛ sumaya. U ka gɛlɛn i ko jahanama, i ka kan ka u mara, u dont mɛn, ani u dont like being too much. Lithium Aw bɛ se ka basigi ka bɔ sira bɛɛ kan (a ɲɛ, 80-90%) ani ITLL bɛ ɲɛ.
fanga min bɛ se ka ta .- Kanpaɲi, o sugu. N bɛ ni bluetti ac200p ye n bɛ min ta kamping tuma dɔw la. A ka gɛlɛn nka i bɛ se ka frigo dɔ boli ka bɔ a la tile 2 ɲɔgɔnna. Pretty cool.
Fana o kuran nɛnɛfɛnw bɛ ka diya tiɲɛ na. N kɔrɔkɛ denkɛ bɛ kelen sɔrɔ a ka kamiyɔn na wa a ka di a ye kosɛbɛ. A bɛ boli ka bɔ litiyɔmu batiri la, ka fɛnw nɛnɛ tile caman kɔnɔ.
A musaka ko (ugh) .
Ok so lithium batiriw sɔngɔ ka gɛlɛn. I n’a fɔ, a sɔngɔ ka gɛlɛn tiɲɛ na. O bluetti min kofɔra, o ye $1600 ye. ka ɲɛsin batiri ma.
Nka heres the thing - ani nin ye waati dɔɔnin ta ne fɛ ka sɔn - u nafa ka bon tiɲɛ na n'i ye baara kɛ n'u ye ka ɲɛ.
O Jackery min tun bɛ n bolo o ye 300 cycles dɔrɔn de ye? N tun bɛ baara kɛ n’a ye don o don n ka ɔridinatɛri kama tuma min na an ye kuran tiɲɛniw sɔrɔ (an ka kuran grid bɛ sumaya yan). O la, 300 cycles tun bɛ i n’a fɔ san. Ni n tun ye asidi plɔmu batiri sigicogo san a tun bɛna kɛ dimi ye kosɛbɛ wa n’a sɔrɔla a tɛna mɛn kosɛbɛ.
Plus no maintenance. Ni asidi plɔmu ye aw ka kan ka ji hakɛw lajɛ, ka u to u ka charge (sara), nin bɛɛ ye fɛn ye min bɛ mɔgɔ tɔɔrɔ. Lithium? Aw bɛ baara kɛ n’a ye dɔrɔn.
Hali bi a bɛ dimi ka o wari caman musaka kɛ ka kɔn o ɲɛ. A tɛna kɛ nkalon ye.
Lakanali fɛnw (dont skip nin yɔrɔ in na kosɛbɛ)
Aw hakili bɛ ne ka Power Bank tasuma na wa? Yeah dont let that happen to you.
Fɛn minnu bɛna f up i ka litiyɔmu batiri:
Funteni jugumanba (sanfɛ i n’a fɔ 140F) .
Nɛnɛ jugumanba (0F duguma kɛrɛnkɛrɛnnenya la ni a bɛ charge) .
Farikolo tiɲɛni (Dont Aw bɛ u fili) .
Charger jugu (aw bɛ baara kɛ ni min ye) .
Ka a to a ka sa kalo caman kɔnɔ .
Ni aw ka batiri fununa walima ni a ye puffy dabila ka baara kɛ n’a ye joona. Dont try to press it back down or "fix" a. O batiri bɛ Kɛ. Aw bɛ a bɔ a la ka ɲɛ.
Fana dont charge batiriw su kelen kɔnɔ u ma kɔlɔsi i ka so. N b’a dɔn bɛɛ b’o kɛ n’u ka telefɔni ye nka ni batiri belebelebaw ye i n’a fɔ kuran baarakɛminɛnw walima kuran feereyɔrɔw... laala dont?
N bɛ n ta sara garazi kɔnɔ sisan kɔkanna ko kɛlen kɔfɛ. Aw bɛ n wele paranoid nka ID sanni aw kana n ka so jeni.
Future stuff maybe?
Bɛɛ bɛ kuma solid state batiriw kan. A bɛ fɔ ko a ka fisa, a ka se ka kɛ mɔgɔ ye, a bɛ charge teliya, o fɛn ɲumanw bɛɛ.
ka "5 sanw bɔ" a bɛ san 10 bɔ sisan lol.
Min bɛ ka kɛ, o ye ko tɔn caman bɛ baara kɛ ni LifePo4 ye fɛnw kama yɔrɔ minnu na girinya wɛrɛ tɛ nafa sɔrɔ. Home Backup Systems, RVw, kurunw, o sugu. A bɛ kɔrɔ - lakana ani a bɛ mɛn.
Saniw bɛ to ka jigin fana min ka di. O bluetti min sanna san 2021, o bɛ i n’a fɔ $300 sɔngɔ ka dɔgɔ sisan. kinda annoying nka fɛn o fɛn.
wrapping this up i guess .
Lithium Battery Technology ka ɲi kosɛbɛ ni i tɛmɛna BS bɛɛ kan ani tiɲɛ na a bɛ whats going on.
Take-aways kunbabaw:
Lifepo4=A ka fisa nka a ka gɛlɛn/a ka bon kosɛbɛ .
Litiyɔmu ion basigilen=A ka dɔgɔn nka a farati ka bon .
funteni nafa ka bon tiɲɛ na .
cycle life ratings ye jigiya ye a ka fisa .
san qualité ni aw bɛ se ka a sɔrɔ .
Dont Leave Batteries dans les chauds serious .
Ani fana dont buy sketchy power banks off AliExpress. A ye o kelen dege cogo gɛlɛn na.
thats ko la. Mike ni aw ye nin kalan aw ka juru bɛ ne la ka nin sɛbɛn lol .
Oh ani fɛn kelen wɛrɛ - ni mɔgɔ dɔ bɛ kurantigi ɲuman dɔn Minneapolis sigida la min bɛ se ka n dɛmɛ ka panne pannew wire up ne ye n’ gosi. Quotes ive been gets are insane.
Ok don sisan. Gonna go charge my power tools sanni n ka ɲinɛ tugun.
