Na u kile ua hlokomela hore motlakase oa betri ea lithium o theoha hang ka mor'a hore o tjhae ka botlalo? Sena ha se sekoli - ke boitšoaro bo tloaelehileng ba 'mele bo tsejoang e leho theoha ha motlakase. Ha re nke mohlala oa rona oa li-cell 8-cell LiFePO₄ (lithium iron phosphate) 24V e le mohlala ho hlalosa.
1. Voltage Drop ke Eng?
Ho latela maikutlo, betri ena e lokela ho fihla ho 29.2V ha e tjhajiloe ka botlalo (3.65V × 8). Leha ho le joalo, ka mor'a ho tlosa mohloli oa matla a ka ntle, motlakase o theoha ka potlako ho ea ho 27.2V (hoo e ka bang 3.4V ka sele). Ke ka lebaka lena:
- Matla a phahameng ka ho fetisisa nakong ea ho tjhaja a bitsoa theCharge Cutoff Voltage;
- Hang ha ho tjhaja ho emisa, polarization ea ka hare e nyamela, 'me motlakase o theohela ka tlhahoOpen Circuit Voltage;
- Lisele tsa LiFePO₄ hangata li tjhaja ho fihla ho 3.5–3.6V, empa tsonaha e khone ho boloka boemo bonanako e telele. Ho e-na le hoo, ba tsitsisa sethaleng sa voltage pakeng tsa3.2V le 3.4V.
Ke ka lebaka leo motlakase o bonahalang o "theoha" hang ka mor'a ho tjhaja.
2. Na Voltage Drop e Ama Bokhoni?
Basebelisi ba bang ba tšoenyehile ka hore ho theoha hona ha motlakase ho ka fokotsa matla a betri a ka sebelisoang. Haele hantle:
- Li-betri tse bohlale tsa lithium li na le litsamaiso tsa taolo tse hahelletsoeng tse lekanyang le ho lokisa bokhoni ka nepo;
- Lisebelisoa tse nang le Bluetooth li lumella basebelisi ho beha leihlomatla a sebele a bolokiloeng(ke hore, matla a ka sebelisoang), le ho lekanya SOC (State of Charge) kamora tefiso e ngoe le e ngoe e felletseng;
- Ka hona,Ho theoha ha motlakase ha ho lebise ho fokotseng matla a ka sebelisoang.
3. Nako ea ho ba Hloko ka Voltage Drop
Le hoja ho theoha ha motlakase ho tloaelehile, ho ka feteletsoa tlas'a maemo a itseng:
- Tšusumetso ea Mocheso: Ho tjhaja mocheso o phahameng kapa haholo o tlase ho ka baka ho theoha ha motlakase ka potlako;
- Botsofali ba Lisele: Keketseho ea ho hanyetsa ka hare kapa litekanyetso tse phahameng tsa ho itšehla thajana le tsona li ka baka ho theoha ha motlakase ka potlako;
- Kahoo basebelisi ba lokela ho latela mekhoa e nepahetseng ea ts'ebeliso le ho lekola bophelo ba betri khafetsa.
Qetello
Ho theoha ha motlakase ke ntho e tloaelehileng ho libeteri tsa lithium, haholo-holo mefuteng ea LiFePO₄. Ka taolo e tsoetseng pele ea betri le lisebelisoa tse bohlale tsa ho beha leihlo, re ka netefatsa ho nepahala ha palo ea matla le bophelo bo botle ba nako e telele le polokeho ea betri.
