Mu makina a batri a lithiamu, kulondola kwa kuyerekezera kwa SOC (State of Charge) ndi muyeso wofunikira kwambiri wa magwiridwe antchito a Battery Management System (BMS). Pansi pa kutentha kosiyanasiyana, ntchitoyi imakhala yovuta kwambiri. Masiku ano, tikulowa mu lingaliro losavuta koma lofunika kwambiri laukadaulo—mphamvu yamagetsi yopanda zero, zomwe zimakhudza kwambiri kulondola kwa kuyerekezera kwa SOC.
Kodi Mphamvu Yothamanga Kwambiri Ndi Chiyani?
Mphamvu ya zero-drift imatanthauza chizindikiro champhamvu chopangidwa mu amplifier circuit pamene palizero input currentkoma chifukwa cha zinthu mongakusintha kwa kutentha kapena kusakhazikika kwa magetsi, malo ogwirira ntchito osasinthasintha a amplifier amasuntha. Kusinthaku kumawonjezeka ndipo kumapangitsa kuti zotsatira zake zisinthe kuchoka pa zero yake yomwe ikuyembekezeka.
Kuti tifotokoze mwachidule, taganizirani sikelo ya bafa ya digito yomwe ikuwonetsaKulemera kwa 5 kg munthu asanapondepoKulemera kwa "mzimu" kumeneko ndikofanana ndi mphamvu yamagetsi yopanda kugwedezeka—chizindikiro chomwe kulibe kwenikweni.
Nchifukwa chiyani mabatire a Lithium ali ndi vuto?
Ma SOC mu mabatire a lithiamu nthawi zambiri amawerengedwa pogwiritsa ntchitokuwerengera kwa coulomb, zomwe zimagwirizanitsa mphamvu yamagetsi pakapita nthawi.
Ngati mphamvu yamagetsi ya zero-drift ndizabwino komanso zopitilira, mwinazabodza kukweza SOC, kunyenga makinawo kuti aganize kuti batire ili ndi chaji yambiri kuposa momwe ilili—mwina kusiya kuyatsa isanakwane nthawi. Mosiyana ndi zimenezi,kusuntha koyipazingayambitseSOC yochepetsedwa, zomwe zimayambitsa chitetezo cha kutuluka msanga.
Pakapita nthawi, zolakwika zonsezi zimachepetsa kudalirika ndi chitetezo cha dongosolo la batri.
Ngakhale kuti mphamvu ya zero-drift current singathe kuchotsedwa kwathunthu, ikhoza kuchepetsedwa bwino pogwiritsa ntchito njira zosiyanasiyana:
- Kukonza bwino zida zamagetsiGwiritsani ntchito ma op-amps ndi zigawo zake zomwe zimathamanga pang'onopang'ono komanso molondola kwambiri;
- Kubwezera kwa algorithmic: Sinthani mosinthasintha kuti mugwiritse ntchito deta yeniyeni monga kutentha, magetsi, ndi magetsi;
- Kusamalira kutenthaKonzani bwino kapangidwe kake ndi kutayika kwa kutentha kuti muchepetse kusalingana kwa kutentha;
- Kuzindikira kolondola kwambiri: Konzani kulondola kwa kuzindikira ma key parameter (voltage ya selo, pack voltage, kutentha, current) kuti muchepetse zolakwika zowerengera.
Pomaliza, kulondola kwa ma microamp onse n'kofunika. Kuthana ndi mphamvu yamagetsi yopanda kugwedezeka ndi gawo lofunika kwambiri popanga njira zoyendetsera mabatire zanzeru komanso zodalirika.
