Nws yog lub meej mom siv roj teeb pov tseg tsuas yog ua ke nrog cov khoom siv uas siv hluav taws xob tsawg. Hauv txhua lwm yam teeb meem, yuav tsum siv roj teeb rov qab. Lawv tuaj yeem them rov qab ntau zaus, uas ua rau muaj kev txuag nqi tseem ceeb.
Cov Lus Qhia
Kauj ruam 1
Txhob them lub roj teeb uas tsis siv rov qab. Qhov no tuaj yeem ua rau electrolyte to thiab txawm tawg. Nws yog qhov tshwj xeeb tshaj yog kev sim sim them cov roj teeb lithium pov tseg: qhov ntsuas kub ntawm cov roj ntsha lithium yog qhov kub nyhiab.
Kauj ruam 2
Muaj kev zam rau txoj cai saum toj no tuaj yeem ua rau cov roj teeb ua kua roj av-zinc roj teeb (nyob ntawm lawv tias lo lus alkaline yog sau). Lawv tuaj yeem raug them nrog asymmetric alternating tam sim no, tus nqi uas hauv milliamperes yog sib npaug rau ib feem kaum ntawm lub peev xwm, qhia tawm hauv milliampere-teev. Lub voj voog ua haujlwm ntawm qhov hluav taws xob no yuav tsum yog 0.5 (dimensionless tus nqi), qhov tam sim no nyob rau hauv kev them nyiaj sab nraud yuav tsum sib npaug rau saum toj no, thiab hauv kev coj tawm - nws ib nrab. Lub sijhawm them nyiaj tsis tshaj li 15 teev, thiab nws yuav tsum muaj nyob rau hauv ib lub thawv tuab-ntsa. Alkaline zinc-manganese hlwb tiv thaiv txog 10 kev them mus ncig. Piv nrog rau cov roj teeb uas muaj ntxig, qhov no me heev.
Kauj ruam 3
Them npib tsib xee-cadmium thiab roj teeb roj nickel-hlau hydride nrog qhov tsis hloov tam sim no, tus nqi uas hauv milliamperes yuav tsum sib haum nrog ib feem kaum ntawm lub peev xwm, qhia tawm hauv milliampere-teev. Lub sijhawm them nyiaj kuj yog 15 teev.
Kauj ruam 4
Lithium-ion roj teeb sib txawv ntawm cov roj teeb lithium pov tseg nyob rau hauv uas lawv muaj lithium nyob rau hauv daim ntawv tsis yog xim hlau. Ua tsaug rau qhov no, lawv tuaj yeem raug them, tab sis cov khoom siv hauv tsev tsis tuaj yeem siv rau qhov no. Siv cov khoom siv hluav taws xob Hoobkas ntawm qhov no nkaus xwb. Yog tias, hais tias, lub teeb nyem hauv tsev xav tias yuav tsum tau lub zog los ntawm lub roj teeb uas npaj rau lub xov tooj ntawm tes, lub roj teeb tuaj yeem them rau hauv lub xov tooj uas ua haujlwm haum. Tsis tas li, cov roj teeb zoo li no tuaj yeem them nrog cov cuab yeej siv thoob ntiaj teb hu ua "qav" hauv cov ntawv. Txhawm rau ua qhov no, thaum nws tua, clamp lub roj teeb rau hauv nws, nias qhov chaw sib txuas mus rau qhov tsis zoo thiab qhov sib tiv tauj zoo, thiab tom qab ntawd, nias lub khawm polarity hloov, ua tiav lub LED ci. Plug nyob rau hauv lub ntaus ntawv thiab qhov thib ob LED yuav pib ntsais. Tsis txhob them thaum nws nres teeb ntsais.
