Vaping a me LiPo batteries

I loko o ka uila uila, ʻo ka mea pōʻino loa ke kumu o ka ikehu, ʻo ia ke kumu he mea nui e ʻike pono i kou "ʻenemi".

A hiki i kēia manawa, no ka vaping, ua hoʻohana nui mākou i nā ʻona Li-ion (nā ʻeke metala tubular o nā anawaena like ʻole a ʻoi aku ka maʻamau o 18650 mau pihi). Eia naʻe, hoʻolako ʻia kekahi mau pahu me kahi pākaukau LiPo. ʻAʻole hiki ke hoʻololi pinepine ʻia kēia mau mea akā hiki ke hoʻopiha hou ʻia a hoʻomau mau ʻia i ka mākeke vaporizer uila.

Eia naʻe, ʻoi aku ka nui o kēia mau ʻōhua LiPo e hoʻomaka ana e ʻike i loko o kā mākou pahu, i kekahi manawa me nā mana keu (a hiki i 1000 Watts a ʻoi aku!), Ma nā ʻano hōʻemi i hiki ke wehe ʻia mai ko lākou hale e uku ʻia. ʻO ka pōmaikaʻi nui o kēia mau pila ʻaʻole hiki ke hōʻole ʻia ko lākou nui a me ko lākou kaumaha i hoʻemi ʻia, e hāʻawi i ka mana ʻoi aku ka nui ma mua o ka mea i loaʻa iā mākou me nā pā Li-Ion.

Hana ʻia kēia kumu aʻo no ʻoe e hoʻomaopopo i ke ʻano o ka hana ʻana o ia pākaukau, nā pilikia, nā pōmaikaʻi o ka hoʻohana ʻana iā lākou a me nā ʻōlelo aʻoaʻo a me nā ʻike he nui.

ʻO ka pākaukau Li Po he mea hoʻouluulu e pili ana i ka lithium i loko o ka mokuʻāina polymer (ʻo ka electrolyte i ke ʻano o kahi gel). Mālama kēia mau pila i ka mana paʻa a lōʻihi i ka manawa. Loaʻa iā lākou ka maikaʻi o ka māmā ma mua o nā ʻāpana Li-Ion, ʻo ia nā mea electrochemical accumulators (hoʻokumu ʻia ka hopena ma ka lithium akā ʻaʻole i loko o ka mokuʻāina ionic), ma muli o ka loaʻa ʻole o ka pahu metala tubular a mākou i ʻike ai.

ʻO LiPos (no ka lithium polymer) i hana ʻia i hoʻokahi a ʻoi aku paha mau mea i kapa ʻia nā cell. Loaʻa i kēlā me kēia kelepona kahi volta nominal o 3,7V no ke kelepona.

E loaʻa i kahi kelepona i hoʻopaʻa ʻia he 100% ka volta o 4,20V, ʻO kā mākou Li-Ion maʻamau, ʻaʻole pono e hoʻonui ʻia ma lalo o ka hoʻopaʻi luku. No ka hoʻokuʻu ʻana, ʻaʻole pono ʻoe e hele ma lalo o 2,8V/3V no ke kelepona. Aia ka volta luku ma 2,5V, ma kēia pae, e maikaʻi kāu accumulator e kiola aku.

Voltage e like me ka hana o ka % ukana

ʻO ka hui ʻana o kahi pākahiko LiPo

Ka hoʻomaopopo ʻana i ka Packaging Battery LiPo

Ma ke kiʻi ma luna nei, ʻo ke kumukānāwai o loko ke ʻano o ka pākaukau 2S2P, No laila aia 2 nā mea i loko Smoʻo a me 2 nā mea i loko Paralle
Ua ʻike ʻia kona mana i ka nui, ʻo ia ka hiki o ka pākaukau 5700mAh
No ka ikaika e hiki ai i ka pākaukau ke hāʻawi, ʻelua mau waiwai: ʻo ka mea mau a me ka piko, ʻo ia ka 285A no ka mua a me 570A no ka lua, me ka ʻike ʻana he ʻelua kekona ka lōʻihi o ke kiʻekiʻe.
ʻO 50C ka nui o ka hoʻokuʻu ʻana o kēia pākaukau, ʻo ia hoʻi hiki iā ia ke hāʻawi i 50 mau manawa o kona hiki ke loaʻa ʻo 5700mAh. No laila hiki iā mākou ke nānā i ka manawa hoʻokuʻu i hāʻawi ʻia ma ka hana ʻana i ka helu ʻana: 50 x 5700 = 285000mA, ʻo ia hoʻi 285A mau.

Ke hoʻolako ʻia ka accumulator me nā ʻāpana he nui, hiki ke hoʻonohonoho ʻia nā mea i nā ʻano like ʻole, a laila e kamaʻilio mākou e pili ana i ka hoʻohui pū ʻana, ma ke ʻano a i ʻole i ka like (a i ʻole nā mea ʻelua i ka manawa like).

Ke hoʻopaʻa ʻia nā ʻāpana like ʻole (no laila o ka waiwai like), hoʻohui ʻia ka volta o nā mea ʻelua, ʻoiai ʻo ka hiki ke hoʻomau i ka mana o ka cell hoʻokahi.

I ka like, i ka wā e hui ʻia ai nā pūnaewele like ʻole, e mau ana ka volta o ke kelepona hoʻokahi ke hoʻohui ʻia ka capacitance o nā mea ʻelua.

I kā mākou hiʻohiʻona, hāʻawi kēlā me kēia mea ʻokoʻa i ka volta o 3.7V me ka mana o 2850mAh. Hāʻawi ka hui Series/Parallel i kahi hiki o (2 series elements 2 x 3.7 =) 7.4V a (2 mau mea e like me 2 x 2850mah =) 5700mah

No ka noho ʻana i ka laʻana o kēia pākaukau o ke kumukānāwai 2S2P, no laila, loaʻa iā mākou 4 mau cell i hoʻonohonoho ʻia penei:

ʻO kēlā me kēia pūnaewele he 3.7V a me 2850mAh, loaʻa iā mākou kahi pākaukau me ʻelua mau ʻāpana like i ka moʻo o (3.7 X 2) = 7.4V a me 2850mAh, i ka like me nā cell ʻelua no ka huina o 7,4V a me (2850 x2 )= 5700mAh.

ʻO kēia ʻano pākaukau, i hana ʻia i nā cell he nui, pono e loaʻa i kēlā me kēia cell ka waiwai like, ʻano like ia i ka wā e hoʻokomo ai ʻoe i kekahi mau pākahi Li-ion i loko o kahi pahu, pono e hoʻopiʻi ʻia kēlā me kēia mea a loaʻa. na waiwai like, hoʻouka, hoʻokuʻu, uila…

Kapa ʻia kēia ke kaulike ana ma waena o nā pūnaewele like ʻole.

He aha ke kaulike?

ʻO ke kaulike ʻana e hiki ai i kēlā me kēia kelepona o ka pūʻolo like ke hoʻouka ʻia ma ka volta like. No ka mea, i ka wā o ka hana ʻana, hiki ke ʻano liʻiliʻi ke kumukūʻai o kā lākou kū'ē kūloko, nona ka hopena o ka hoʻonui ʻana i kēia ʻokoʻa (ʻoiai ka liʻiliʻi) i ka manawa ma waena o ka uku a me ka hoʻokuʻu. No laila, aia ka pilikia o ka loaʻa ʻana o kahi mea e ʻoi aku ke koʻikoʻi ma mua o kahi ʻē aʻe, e alakaʻi ai i ka ʻaʻahu mua o kāu pākaukau a i ʻole nā hana hewa.

ʻO ia ke kumu i ʻoi aku ka maikaʻi, i ke kūʻai ʻana i kāu charger, e koho i kahi charger me ka hana kaulike a i ka wā e hoʻouka hou ai, pono ʻoe e hoʻopili i nā plug ʻelua: ka mana a me ke kaulike (a i ʻole ke kaulike)

Hiki ke loaʻa i nā hoʻonohonoho ʻē aʻe no kāu mau pila me, no ka laʻana, nā mea i ka moʻo o ke ʻano 3S1P:

Hiki nō hoʻi ke ana i nā volta ma waena o nā mea like ʻole me ka hoʻohana ʻana i ka multimeter. Na ke kiʻikuhi ma lalo nei e kōkua iā ʻoe e hoʻonohonoho pono i kāu mau kaula no kēia mana.

Pehea e hoʻouka ai i kēia ʻano pākaukau

Hoʻopiʻi ʻia kahi pākaukau lithium-based i ka volta mau, he mea nui ʻaʻole e ʻoi aku ma mua o 4.2V no kēlā me kēia kelepona ma lalo o ka hoʻopaʻi o ka deterioration o ka pā. Akā, inā ʻoe e hoʻohana i kahi pānaʻi kūpono no nā pā LiPo, hoʻokele wale ia i kēia paepae.

Hoʻopaʻa ka hapa nui o nā ʻaniani LiPo ma 1C, ʻo ia ka mea lohi a ʻoi aku ka palekana. ʻOiaʻiʻo, ʻae kekahi mau ʻaniani LiPo i nā uku wikiwiki o 2, 3 a i ʻole 4C, akā ʻo kēia ʻano o ka hoʻouka hou ʻana, inā ʻae ʻia, hoʻopau koke i kāu mau pila. He ʻano like ia me kāu pākaukau Li-Ion ke hoʻopaʻa ʻoe iā 500mAh a i ʻole 1000mAh.

Laʻana: inā ʻoe e hoʻouka a 2S 2000 mAh pākaukau me kāna charger i hoʻolako ʻia me kahi hana kaulike hoʻohui:

- Huli mākou i kā mākou charger a koho mākou ma kā mākou charger a ka hoʻouka ʻana a me ke kaupaona ʻana i ka papahana "lipo".

- Hoʻohui i nā kumu 2 o ka pākaukau: hoʻouka / hoʻokuʻu (ʻo ka mea nui me nā uea 2) a me ke kaulike (ʻo ka mea liʻiliʻi me nā uea he nui, ma ʻaneʻi i ka laʻana he 3 mau uea no ka mea 2 mau mea)

- Hoʻolālā mākou i kā mākou charger:

- 2S pākaukau => 2 mau mea => ua hōʻike ʻia ma kāna charger “2S” a i ʻole nb o nā ʻeleʻele=2 (no laila no ka ʻike 2*4.2=8.4V)

– 2000 mah pākaukau => hana ia a capacité o ka pākaukau 2Ah => hōʻike ia ma kāna hoʻouka a ka hoʻouka ʻana i kēia manawa o 2A

- hoʻomaka e hoʻopaʻa.

nui: Ma hope o ka hoʻohana ʻana i kahi pānaʻi LiPo mana kiʻekiʻe (kūʻai haʻahaʻa loa), hiki ke ʻoi aku ka wela o ka pā. No laila he mea nui e hoʻomaha i kahi pā lipo no 2 a i ʻole 3 mau hola ma mua o ka hoʻouka hou ʻana. ʻAʻole loa e hoʻopiha hou i kahi pākaukau LiPo i ka wā wela (paʻa ʻole)

Ke kaulike:

ʻO kēia ʻano pākaukau i hana ʻia i nā mea he nui, pono ia e noho kēlā me kēia kelepona i loko o kahi pā uila ma waena o 3.3 a me 4.2V.

Eia kekahi, inā ʻaʻole kaulike kekahi o nā pūnaewele, me hoʻokahi mea ma 3.2V a ʻo kekahi ma 4V, hiki paha i kāu kauā ke hoʻonui i ka mea 4V i ʻoi aku ma mua o 4.2V e uku ai i ka nalowale o ka mea ma 3.2 V i mea e loaʻa ai ka uku holoʻokoʻa o 4.2V. ʻO kēia ke kumu he mea nui ke kaulike. ʻO ka pilikia mua i ʻike ʻia ʻo ka pehu ʻana o ka ʻeke me kahi pahū hiki ke hopena.

E `ike :

Mai hoʻokuʻu i kahi pākahi ma lalo o 3V (pilikia o ka hiki ʻole ke hoʻihoʻi ʻia)
He lōʻihi ke ola o ka pila lipo. Ma kahi o 2 a 3 makahiki. ʻOiai ʻaʻole mākou e hoʻohana. Ma keʻano laulā, ma kahi o 100 mau kaʻina hoʻoiho / hoʻokuʻu me ka hana kiʻekiʻe.
ʻAʻole hana maikaʻi ka pila lipo i ke anuanu, ʻo ka pae wela ma kahi o kona maikaʻi loa ma kahi o 45°C
ʻO ka pākaukau i hoʻopaʻa ʻia ʻo ia ka puʻupuʻu make, pono ʻoe e kāpae iā ia (ʻaʻole e hoʻololi ka lipine i kekahi mea).
Mai hoʻopaʻa i ka pila wela, ʻeha a pehu paha
Inā ʻaʻole ʻoe e hoʻohana hou ana i kāu mau ʻanuʻu, e like me nā pākahi Li-Ion, e mālama i ka ʻeke ma ka hapalua o ka uku (ʻo ia hoʻi ma kahi o 3.8V, e ʻike i ka papa hoʻouka ma luna)
Me kahi pākaukau hou, i ka wā o ka hoʻohana mua ʻana he mea nui ʻaʻole e piʻi i luna me nā mana vape kiʻekiʻe loa (break-in), e lōʻihi loa ia.
Mai hōʻike aku i kāu mau pila ma nā wahi e piʻi ai ka mahana ma mua o 60°C (kaʻa i ke kauwela)
Inā wela ka pila iā ʻoe, e wehe koke i ka pākaukau a kali i kekahi mau minuke i ka neʻe ʻana aku, no ka maʻalili. E nānā hope ʻaʻole i poino.

I ka hōʻuluʻulu ʻana, ʻaʻole ʻoi aku ka pōʻino a i ʻole ka liʻiliʻi o nā pākahi Li-Po ma mua o nā pā Li-Ion, ʻoi aku ka palupalu a koi aku i ka hoʻokō pono ʻana i nā ʻōlelo kumu. Ma ka ʻaoʻao ʻē aʻe, hiki iā lākou ke hoʻonui i nā mana kiʻekiʻe loa ma o ka hoʻohui ʻana i nā volta, nā kaha a me ka ikaika i ka leo i hoʻemi ʻia e ka hoʻopili māmā a me ka māmā.

Mahalo mākou i ka pūnaewele http://blog.patrickmodelisme.com/post/qu-est-ce-qu-une-batterie-lipo i lilo i kumu o ka ʻike a mākou e aʻo aku ai iā ʻoe e heluhelu inā makemake ʻoe i ka hana hoʻohālike a/a i ʻole ka ikehu.
