Mabatire a Vaping ndi LiPo

Mu vaporizer yamagetsi, chinthu chowopsa kwambiri chimakhalabe gwero lamphamvu, chifukwa chake ndikofunikira kudziwa bwino "mdani" wanu.

Mpaka pano, chifukwa cha vaping, timagwiritsa ntchito mabatire a Li-ion (mabatire achitsulo a tubular amitundu yosiyanasiyana komanso mabatire ambiri a 18650). Komabe, mabokosi ena ali ndi batire ya LiPo. Nthawi zambiri izi sizisinthana koma zimangowonjezeredwanso ndipo zimakhalabe zochepa pamsika wamagetsi a vaporizer.

Komabe, ochulukirachulukira mwa mabatire a LiPo awa akuyamba kuwonekera m'mabokosi athu, nthawi zina ndi mphamvu zochulukirapo (mpaka 1000 Watts ndi zina zambiri!), M'mawonekedwe ochepetsedwa omwe amatha kuchotsedwa mnyumba zawo kuti azilipiritsa. Ubwino waukulu wa mabatirewa mosakayikira ndi kukula kwawo ndi kulemera kwawo komwe kumachepetsedwa, kuti apereke mphamvu zazikulu kuposa zomwe tili nazo mwachizolowezi ndi mabatire a Li-Ion.

Phunziroli lapangidwira kuti mumvetsetse momwe batri yotere imapangidwira, kuopsa kwake, ubwino wogwiritsa ntchito ndi malangizo ena ambiri othandiza.

Battery ya Li Po ndi accumulator yochokera ku lithiamu mu polima (electrolyte ili mu mawonekedwe a gel). Mabatirewa amakhalabe ndi mphamvu zokhazikika komanso zokhalitsa pakapita nthawi. Amakhalanso ndi mwayi wokhala opepuka kuposa mabatire a Li-Ion, omwe ndi ma electrochemical accumulators (zomwe zimatengera lifiyamu koma osati m'boma la ionic), chifukwa chosowa ma CD azitsulo a tubular omwe timawadziwa.

LiPos (ya lithiamu polima) amapangidwa ndi chinthu chimodzi kapena zingapo zotchedwa maselo. Selo lililonse lili ndi mphamvu yamagetsi ya 3,7V pa selo.

Selo yokhala ndi 100% yokhala ndi voteji ya 4,20V, ponena za Li-Ion yathu yapamwamba, mtengo womwe suyenera kupyola pansi pa chilango cha chiwonongeko. Za kutulutsa, simuyenera kupita pansi pa 2,8V/3V pa selo. Magetsi owononga pokhala pa 2,5V, pamlingo uwu, accumulator yanu idzakhala yabwino kutaya.

Kumvetsetsa LiPo Battery Packaging

Pa chithunzi pamwambapa, malamulo amkati ndi a batri 2S2P, Ndiye pali 2 zinthu mu Sseries ndi 2 zinthu mu Pzonse
Kuthekera kwake kumadziwika kwambiri, ndiko kuthekera kwa batri komwe kuli 5700mAh
Pakuchulukira komwe batire lingapereke, pali zikhalidwe ziwiri: imodzi yopitilira ndi pachimake, yomwe ndi 285A yoyamba ndi 570A yachiwiri, podziwa kuti pachimake kumatenga masekondi awiri.
Kutulutsa kwa batire iyi ndi 50C kutanthauza kuti ikhoza kutulutsa nthawi 50 ya mphamvu yake yomwe pano ndi 5700mAh. Chifukwa chake titha kuyang'ana kutulutsa komwe kwaperekedwako powerengera: 50 x 5700 = 285000mA, i.e. 285A mosalekeza.

Pamene accumulator ili ndi maselo angapo, zinthuzo zimatha kukonzedwa m'njira zosiyanasiyana, timalankhula za kulumikizana kwa ma cell, motsatizana kapena mofananira (kapena zonse nthawi imodzi).

Pamene maselo ofanana ali mndandanda (kotero mtengo womwewo), mphamvu ya magetsi awiriwo imawonjezedwa, pamene mphamvu imakhalabe ya selo imodzi.

Mofananamo, maselo ofanana akaphatikizidwa, mphamvu yamagetsi imakhala ya selo imodzi pamene mphamvu ya awiriwo ikuwonjezeredwa.

Mu chitsanzo chathu, chinthu chilichonse chosiyana chimapereka mphamvu ya 3.7V yokhala ndi mphamvu ya 2850mAh. Mgwirizano wa Series/Parallel umapereka kuthekera kwa (2 mndandanda wazinthu 2 x 3.7 =) 7.4V ndi (2 zinthu kufanana 2 x 2850mah =) 5700mah

Kuti tikhalebe chitsanzo cha batire iyi ya 2S2P Constitution, tili ndi ma cell anayi omwe adakonzedwa motere:

Selo lililonse pokhala 3.7V ndi 2850mAh, tili ndi batire yokhala ndi maselo awiri ofanana pamndandanda wa (3.7 X 2) = 7.4V ndi 2850mAh, kufananiza ndi ma cell awiri omwewo pamtengo wa 7,4V ndi (2850 x2 )= 5700mAh.

Batire yamtunduwu, yopangidwa ndi ma cell angapo, imafuna kuti selo lililonse likhale ndi mtengo wofanana, zimakhala ngati mukayika mabatire angapo a Li-ion m'bokosi, chinthu chilichonse chimayenera kulingidwa limodzi ndikukhala nacho. katundu yemweyo, mtengo, kutulutsa, voteji…

Izi zimatchedwa kusanja pakati pa ma cell osiyanasiyana.

Kodi Balance ndi chiyani?

Kusanja kumapangitsa kuti selo lililonse la paketi imodzi lizilipiritsidwa pamagetsi omwewo. Chifukwa, pakupanga, mtengo wa kukana kwawo kwamkati ukhoza kusiyana pang'ono, zomwe zimakhala ndi zotsatira zolimbikitsa kusiyana kumeneku (ngakhale kochepa) pakapita nthawi pakati pa malipiro ndi kutulutsa. Chifukwa chake, pali chiwopsezo chokhala ndi chinthu chomwe chitha kupsinjika kwambiri kuposa china, zomwe zingapangitse kuti batire lanu lisamakhale nthawi yayitali kapena kulephera.

Ichi ndichifukwa chake kuli bwino, pogula chojambulira chanu, kusankha chojambulira chokhala ndi ntchito yofananira ndipo mukamangitsanso, muyenera kulumikiza mapulagi awiriwa: mphamvu ndi kusanja (kapena kusanja)

Ndizotheka kupeza masinthidwe ena a mabatire anu, mwachitsanzo, zinthu zamtundu wa 3S1P:

Ndikothekanso kuyeza ma voltages pakati pa zinthu zosiyanasiyana pogwiritsa ntchito multimeter. Chithunzi chili m'munsichi chidzakuthandizani kuyika bwino zingwe zanu kuti muziwongolera izi.

Momwe mungalipire batire yamtunduwu

Battery yochokera ku lithiamu imayikidwa pamagetsi nthawi zonse, ndikofunika kuti musapitirire 4.2V pa selo, apo ayi batire idzawonongeka. Koma, ngati mugwiritsa ntchito chojambulira choyenera cha mabatire a LiPo, imayang'anira gawo ili lokha.

Mabatire ambiri a LiPo amalipira pa 1C, uku ndiye kutsika pang'onopang'ono komanso kulipiritsa kotetezeka. Zowonadi, mabatire ena a LiPo amavomereza kuyitanitsa mwachangu kwa 2, 3 kapena 4C, koma njira iyi yowonjezeretsa, ngati ilandilidwa, imawononga mabatire anu nthawi isanakwane. Zimakhala ngati ndi batire yanu ya Li-Ion mukamachapira 500mAh kapena 1000mAh.

Chitsanzo: mukanyamula a 2S 2000 mAh batire ndi charger yake yokhala ndi integrated balancing function:

- Timayatsa charger yathu ndikusankha pa charger yathu a charging/bancing “lipo” program

- Lumikizani zitsulo ziwiri za batri: chowongolera / kutulutsa (chachikulu chokhala ndi mawaya 2) ndikusanja (kaching'ono kakang'ono kamene kali ndi mawaya ambiri, apa mu chitsanzo chili ndi mawaya atatu chifukwa zinthu ziwiri)

- Timakonza charger yathu:

- 2S batire => 2 zinthu => ikuwonetsedwa pa charger yake “2S” kapena nb ya zinthu=2 (kotero kuti mudziwe 2*4.2=8.4V)

- 2000 mah batire => imapanga a luso ya batire ya 2Ah => ikuwonetsa pa mtengo wake a pakali pano mwa 2a

- Yambani kulipira.

zofunika: Mutagwiritsa ntchito batire yamphamvu ya LiPo (yotsika kwambiri kukana), ndizotheka kuti batire imakhala yotentha kwambiri. Chifukwa chake ndikofunikira kwambiri kuti batire ya lipo ipume kwa maola awiri kapena atatu musanayikenso. OSAYAMBIRAnso batire ya LiPo ikatentha (yosakhazikika)

Kusanja:

Batire yamtunduwu imapangidwa ndi zinthu zingapo, ndikofunikira kuti selo lililonse likhalebe pakati pa 3.3 ndi 4.2V.

Komanso, ngati imodzi mwamaselo ili ndi vuto, ndi chinthu chimodzi pa 3.2V ndi china pa 4V, ndizotheka kuti chojambulira chanu chikuwonjezera chigawo cha 4V kupitirira 4.2V kuti chibwezere kutayika kwa chinthucho pa 3.2 V kuti mupeze ndalama zonse za 4.2V. Ichi ndichifukwa chake kulinganiza ndikofunikira. Chiwopsezo choyamba chowoneka ndi kutupa kwa paketi ndi kuphulika kotheka chifukwa.

Kudziwa:

Osatulutsa batire pansi pa 3V (chiwopsezo cha batire yosachiritsika)
Batire ya lipo imakhala ndi moyo wautali. Pafupifupi zaka 2 mpaka 3. Ngakhale sitigwiritsa ntchito. Nthawi zambiri, ndi kuzungulira kwa 100 / kutulutsa komwe kumakhala kokwanira.
Batire ya lipo siigwira ntchito bwino pakazizira kwambiri, kutentha komwe kuli bwino kwambiri kumakhala pafupifupi 45°C.
Batire yoboola ndi batire yakufa, muyenera kuyichotsa (tepi sisintha chilichonse).
Osayesa batire yotentha, yoboola kapena yotupa
Ngati simukugwiritsanso ntchito mabatire anu, ngati mabatire a Li-Ion, sungani paketiyo pamalipiro atheka (ie mozungulira 3.8V, onani tebulo lolipiritsa pamwambapa)
Ndi batire yatsopano, pakugwiritsa ntchito koyamba ndikofunikira kuti musapite ndi mphamvu za vape zokwera kwambiri (kusweka), zimatha nthawi yayitali.
Osawonetsa mabatire anu m'malo omwe kutentha kumatha kufika kupitilira 60 ° C (galimoto m'chilimwe)
Ngati batire ikuwoneka yotentha kwa inu, chotsani batire nthawi yomweyo ndikudikirira mphindi zingapo mukusuntha, kuti izizizire. Pomaliza fufuzani kuti sizinawonongeke.

Mwachidule, mabatire a Li-Po sali owopsa kapena ochepera kuposa mabatire a Li-Ion, ndi osalimba kwambiri ndipo amafunikira kutsatira mosamalitsa malangizo oyambira. Kumbali inayi, amapangitsa kuti ziwonjezeke ku mphamvu zapamwamba kwambiri pophatikiza ma voltages, mphamvu ndi kulimba mu voliyumu yochepetsedwa ndi ma CD osinthika komanso opepuka.

Tikuthokoza malowa http://blog.patrickmodelisme.com/post/qu-est-ce-qu-une-batterie-lipo zomwe zidakhala ngati gwero lachidziwitso komanso zomwe tikukulangizani kuti muwerenge ngati mumakonda kupanga zitsanzo ndi / kapena mphamvu.
