Kukana kwa batri mkati ndi chizindikiro chofunikira kwambiri pakuwunika thanzi ndi moyo wantchito wa mabatire. Pakapita nthawi, kukana kwamkati kumawonjezeka pang'onopang'ono, kumakhudza kwambiri ntchito. Izi zitha kuchititsa kuti madzi azitulutsa pang'onopang'ono, kutayika kwamphamvu kwamphamvu, komanso kutentha kwa magwiridwe antchito. Makamaka, pamene kukana kwa mkati kumaposa 25% ya mtengo wamba, mphamvu ya batri imachepa kwambiri, kusokoneza kukhazikika kwa dongosolo. Chifukwa chake, kuyang'anira zenizeni zenizeni za kukana kwa batri ndikofunikira.
1. Direct Current (DC) Njira Yotulutsira
Njirayi imaphatikizapo kutulutsa batri ndi mphamvu yayikulu ndikuwerengera kukana kwamkati kutengera kutsika kwamagetsi. Ngakhale imapereka kulondola kwakukulu, imayambitsa kusokonezeka kwa batri, kufulumizitsa ukalamba. Chotsatira chake, njirayi imagwiritsidwa ntchito makamaka pofufuza ndi kupanga maulendo oyendetsa ndege ndipo siyenera kuyang'anitsitsa kwa nthawi yaitali.
2. Njira Yosinthira Panopa (AC) Impedans
Pogwiritsa ntchito ma alternating apano a pafupipafupi komanso kugwiritsa ntchito mfundo za Ohm's Law ndi capacitance, njirayi imayesa kukana kwamkati. Mosiyana ndi njira ya DC yotulutsa, njira ya AC impedance imapewa kuwononga moyo wa batri ndipo imapereka zotsatira zomwe sizidalira pafupipafupi. Miyezo yomwe imatengedwa pafupipafupi 1kHz ndiyokhazikika kwambiri. Njirayi imagwiritsidwa ntchito kwambiri m'makampani ndipo imakwaniritsa zolondola kwambiri, ndi malire a zolakwika pakati pa 1% ndi 2%.
DFUN yapanga kusintha kwatsopano panjira yachikhalidwe ya AC impedance — AC Low Current Discharge Method. Pogwiritsa ntchito makina osinthira osapitilira 2A ndikuyesa kusinthasintha kwamagetsi, mphamvu yamkati ya batri imatha kuwerengedwa molondola pakanthawi kochepa (pafupifupi sekondi imodzi).
Ubwino waukulu:
Kulondola Kwambiri: Kulondola kwa miyeso kuli pafupi ndi 1%, zotsatira zake zimakhala zofanana ndi zamtundu wachitatu monga Hioki ndi Fluke.
Kukaniza Kwamkati |
2V Batiri: 0.1 ~ 50 mΩ |
Kubwereza: ±(1.0% + 25 µΩ) |
Kusintha: 0.001 mΩ |
12V Batire: 0.1 ~ 100 mΩ |
Palibe Zokhudza Thanzi La Battery: Pokhala ndi matalikidwe ochepera apano komanso otulutsa pang'ono, njirayi siyivulaza batire kapena kufulumizitsa ukalamba.
Kuwunika Nthawi Yeniyeni: Kumathandizira kupeza nthawi yeniyeni ya batri, kuteteza bwino kuwonongeka kwa magwiridwe antchito chifukwa chakuwonjezeka kwa mkati.
Kugwiritsa Ntchito Mosiyanasiyana: Ukadaulowu sumangogwira ntchito pamabatire a lead-acid komanso ndiwothandiza pakuwunika kukana kwamkati mumitundu ina yamitundu yosiyanasiyana.
Onetsetsani kuti mabatire anu akukhalabe mumkhalidwe wabwino, kukulitsa kukhazikika ndi kudalirika kwamagetsi anu.
