Atagula mtundu wina wa chojambulira, ambiri akukumana ndi vuto la momwe angaligwiritsire ntchito bwino? Imodzi mwa mitundu yayikulu ndi mabatire a nickel-metal hydride (NiMh). Iwo ali ndi zenizeni zawo momwe angayankhire iwo.
Kodi mungayang'ane bwanji batani a NiMh?
Makamaka a mabatire a NiMh amatha kutentha ndi kutengeka. Izi zingapangitse zotsatira zoipa zomwe zimakhudza kuthekera kwa chipangizochi kuti chigwiritse ntchito ndi kupereka ndalama.
Pafupifupi mabatire onse a mtundu uwu amagwiritsa ntchito njira "delta" yomwe imadziwika bwino kwambiri. Zimakupatsani inu kusonyeza mapeto a chilango. Malo a matepi a nickel ndikuti magetsi a batsi a NiMh omwe amalembedwa amayamba kuchepa ndi kuchuluka kwake kochepa.
Kodi mungagwiritse ntchito bwanji batani a NiMh?
Njira ya "delta" imatha kugwira ntchito bwino ndi mazira a 0,3C kapena apamwamba. Mtengo wa C umagwiritsidwa ntchito kusonyeza mphamvu yeniyeni ya rechargeable aa ni NiMh batri.
Choncho, kuti mukhale ndi ngongole ya 1500 mAh, njira ya delta yapamwamba idzagwira ntchito moyenera ndi pakalipano pakalipa ya 0.3x1500 = 450 mA (0.5 A). Ngati pakali pano pali mtengo wapatali, pali ngozi yaikulu kuti pamapeto pake, magetsi pa bateri sadzayamba kuchepa, ndipo idzakhala pamtunda wina. Izi zidzachititsa kuti chojambuliracho chisamvetsetse mapeto a msonkhanowo. Zotsatira zake, sipadzakhala kutambasula ndikupitiriza kubwezeretsanso. Mphamvu ya betri idzacheperachepera, zomwe zidzasokoneza ntchito yake.
Pakali pano, pafupifupi ndalama zonse zingapereke kwa 1C. Pankhaniyi,
Kuti muonjezere moyo wa chojambulira cha nickel-metal hydride, mungathe kulimbikitsa kusunga ndi ndalama zochepa (30-50%).
Choncho, kuyendetsa molondola kwa batride ya metal ya nickel-metal kumakhudzanso ntchito yake ndikuthandizani kuti ikhale yogwirizana.
