Batire ya lithiamuzimanenedwa kuti n'zosavuta, kwenikweni, si zovuta kwambiri, anati zosavuta, kwenikweni, si zophweka.Ngati mukuchita nawo makampaniwa, ndiye kuti ndikofunikira kudziwa mawu omwe amagwiritsidwa ntchito pamakampani a batri a lithiamu, ndiye kuti, ndi mawu ati omwe amagwiritsidwa ntchito pamakampani a batire a lithiamu?
Mawu omwe amagwiritsidwa ntchito pamakampani a batri a lithiamu
1.Charge-Rate/Scharge-Rate
Zimasonyeza kuchuluka kwa magetsi omwe akuyenera kulipiritsa ndi kutulutsa, omwe amawerengedwa ngati kuchuluka kwa mphamvu ya batri, yomwe imatchedwa ochepa C. Monga batri yokhala ndi mphamvu ya 1500mAh, ikuti 1C = 1500mAh, ngati itatulutsidwa 2C imatulutsidwanso ndi mphamvu ya 3000mA, 0.1C ndipo imatulutsidwa ndi kutulutsidwa ndi 150mA.
2.OCV: Open Circuit Voltage
Mphamvu ya batri nthawi zambiri imatanthawuza mphamvu yamagetsi (yomwe imatchedwanso voliyumu) ya batri ya lithiamu.Mphamvu yamagetsi ya batire ya lithiamu wamba nthawi zambiri imakhala 3.7V, ndipo timayitchanso nsanja yake yamagetsi 3.7V.Ndi voteji nthawi zambiri timatchula mphamvu yamagetsi yotseguka ya batri.
Pamene batire ndi 20-80% ya mphamvu, voteji anaikira mozungulira 3.7V (mozungulira 3.6 ~ 3.9V), mkulu kwambiri kapena otsika kwambiri mphamvu, voteji zimasiyanasiyana mosiyanasiyana.
3. Mphamvu / Mphamvu
Mphamvu (E) yomwe batire imatha kutulutsa ikatulutsidwa pamlingo wina wake, mu Wh (watt hours) kapena KWh (makilowati maola), kuphatikiza 1 KWh = 1 kWh yamagetsi.
Mfundo yofunikira imapezeka m'mabuku a physics, E=U*I*t, yomwe ilinso yofanana ndi mphamvu ya batri yochulukitsidwa ndi mphamvu ya batri.
Ndipo ndondomeko ya mphamvu ndi, P = U * I = E / t, yomwe imasonyeza kuchuluka kwa mphamvu zomwe zingathe kutulutsidwa pa nthawi imodzi.Chigawo ndi W (watt) kapena KW (kilowatt).
Batri yokhala ndi mphamvu ya 1500 mAh, mwachitsanzo, imakhala ndi mphamvu yamagetsi ya 3.7V, kotero mphamvu yofananira ndi 5.55Wh.
4.Kukaniza
Monga malipiro ndi kutulutsa sizingafanane ndi magetsi abwino, pali kukana kwina kwa mkati.Kukaniza kwamkati kumadya mphamvu ndipo ndithudi kukana kwamkati kumakhala kocheperako.
Kukana kwa mkati kwa batire kumayesedwa mu milliohms (mΩ).
Kukaniza kwamkati kwa batire wamba kumakhala ndi kukana kwa ohmic mkati ndi kukana kwa polarized mkati.Kukula kwa kukana kwamkati kumakhudzidwa ndi zinthu za batri, kupanga mapangidwe, komanso mapangidwe a batri.
5.Cycle Life
Kuthamangitsidwa kwa batri ndi kutulutsa kamodzi kumatchedwa kuzungulira, moyo wozungulira ndi chizindikiro chofunikira cha moyo wa batri.Muyezo wa IEC umanena kuti mabatire a lithiamu a foni yam'manja, 0.2C imatulutsa 3.0V ndi 1C mpaka 4.2 V. Pambuyo pa 500 yobwerezabwereza, mphamvu ya batri iyenera kukhala yoposa 60% ya mphamvu yoyamba.Mwanjira ina, moyo wozungulira wa batri ya lithiamu ndi nthawi 500.
Muyezo wa dziko umanena kuti pambuyo pa maulendo a 300, mphamvu iyenera kukhalabe pa 70% ya mphamvu zoyamba.Mabatire omwe ali ndi mphamvu yochepera 60% ya mphamvu yoyamba ayenera kuganiziridwa kuti angatayidwe.
6.DOD: Kuzama kwa Discharger
Amatanthauzidwa ngati kuchuluka kwa mphamvu yotulutsidwa mu batri ngati gawo limodzi la kuchuluka kwake komwe kudavoteredwa.Kuzama kwa batire ya lithiamu nthawi zambiri, kumachepetsa moyo wa batri.
7.Kudula-Kutentha kwa Voltage
Mphamvu yamagetsi imagawidwa kukhala voteji yoyimitsa ndi kutulutsa voteji, kutanthauza mphamvu yomwe batire silingayimitsidwe kapena kutulutsidwanso.Kuthamangitsa voteji ya lithiamu batire nthawi zambiri ndi 4.2V ndipo voteji yomaliza ndi 3.0V.Kulipiritsa mozama kapena kutulutsa batire ya lithiamu kupitilira mphamvu yomaliza ndikoletsedwa.
8.Kudzitulutsa
Zimatanthawuza kutsika kwa mphamvu ya batri panthawi yosungidwa, zomwe zimawonetsedwa ngati kuchepa kwazinthu pa nthawi imodzi.Mlingo wodzitulutsa wa batri wamba wa lithiamu ndi 2% mpaka 9% / mwezi.
9.SOC (State of Charge)
Zimatanthawuza kuchuluka kwa batire yomwe yatsala ndikuthanso kutha kutha, 0 mpaka 100%.Imawonetsa kuchuluka kotsalira kwa batri.
10.Kukhoza
Zimatanthawuza kuchuluka kwa mphamvu zomwe zingapezeke kuchokera ku batri ya lithiamu pansi pazifukwa zina zotuluka.
Njira yamagetsi ndi Q=I*t mu coulombs ndipo gawo la mphamvu ya batri limatchulidwa ngati Ah (maola ampere) kapena mAh (maola a milliampere).Zikutanthauza kuti batire ya 1AH ikhoza kutulutsidwa kwa ola limodzi ndi mphamvu ya 1A ikadzakwana.
