Kukho iimpawu ezintandathu eziphambili zeIibhetri zeNiMHIimpawu zokutshaja kunye neempawu zokukhupha itshaja ezibonisa ikakhulu iimpawu zokusebenza, iimpawu zokuzikhupha kunye neempawu zokugcina ixesha elide ezibonisa ikakhulu iimpawu zokugcina, kunye neempawu zobomi bomjikelo kunye neempawu zokhuseleko ezibonisa ikakhulu ukuhlanganiswa. Zonke zimiselwa lulwakhiwo lwebhetri etshajayo, ikakhulu kwindawo ekuyo, kunye neempawu ezicacileyo zokuchaphazeleka kakhulu bubushushu kunye nomsinga. Okulandelayo nathi ukujonga iimpawu zebhetri yeNiMH.

1. Iimpawu zokutshaja zeebhetri zeNiMH.

XaIbhetri ye-NiMHUkunyuka komsinga wokutshaja kunye (okanye) nokwehla kobushushu bokutshaja kuya kubangela ukuba i-voltage yokutshaja yebhetri inyuke. Ngokubanzi kubushushu obuphakathi kwe-0 ℃ ~ 40 ℃ kusetyenziswa i-charge yangoku engaguqukiyo engadluli kwi-1C, ngelixa ukutshaja phakathi kwe-10 ℃ ~ 30 ℃ kunokufumana ukusebenza okuphezulu kokutshaja.

Ukuba ibhetri idla ngokutshajwa kwindawo enobushushu obuphezulu okanye obuphantsi, oko kuya kubangela ukwehla kokusebenza kwebhetri yamandla. Ukuze itshajwe ngokukhawuleza ngaphezu kwe-0.3C, amanyathelo okulawula ukutshaja ayimfuneko. Ukutshaja okuphindaphindiweyo kuya kunciphisa ukusebenza kwebhetri etshajwayo, ngoko ke, kufuneka kubekho amanyathelo okukhusela ukutshaja aphezulu naphantsi.

2. Iimpawu zokukhupha iibhetri zeNiMH.

Iqonga lokukhuphaIbhetri ye-NiMHyi-1.2V. Okukhona umbane uphezulu kwaye ubushushu buphantsi, kokukhona i-voltage yokukhupha kunye nokusebenza kakuhle kokukhupha ibhetri etshajwayo kuya kuba sezantsi, kwaye umbane ophezulu wokukhupha oqhubekayo webhetri etshajwayo yi-3C.

I-voltage yokucima umbane kwiibhetri ezinokutshajwa kwakhona idla ngokubekwa kwi-0.9V, kwaye imo ye-IEC standard charge/discharge ibekwe kwi-1.0V, kuba, ngaphantsi kwe-1.0V, umsinga ozinzileyo unokubonelelwa ngokubanzi, kwaye ngaphantsi kwe-0.9V umsinga omncinci unokubonelelwa, ngoko ke, i-voltage yokucima umbane kwiibhetri ze-NiMH inokuthathwa njengoluhlu lwe-voltage ukusuka kwi-0.9V ukuya kwi-1.0V, kwaye ezinye iibhetri ezinokutshajwa kwakhona zinokubhaliselwa kwi-0.8V. Ngokubanzi, ukuba i-voltage yokucima ibekwe phezulu kakhulu, amandla ebhetri ayinakusetyenziswa ngokupheleleyo, kwaye ngokuchaseneyo, kulula kakhulu ukubangela ibhetri etshajwayo ikhuphe umbane kakhulu.

3. Iimpawu zokuzikhupha ngokwazo iibhetri zeNiMH.

Ibhekisa kwinto yokulahleka komthamo xa ibhetri etshajwayo itshajwe ngokupheleleyo kwaye igcinwe kwisekethe evulekileyo. Iimpawu zokuzikhupha zichaphazeleka kakhulu bubushushu obungqongileyo, kwaye okukhona ubushushu buphezulu, kokukhona ilahleko yomthamo webhetri etshajwayo emva kokugcinwa.

4. Iimpawu zokugcina ixesha elide zeebhetri zeNiMH.

Eyona nto ibalulekileyo kukukwazi ukubuyisa amandla eebhetri zeNiMH. Ngexesha elide (njengonyaka) xa zisetyenziswa emva kokugcinwa, amandla ebhetri etshajwayo anokuba mancinci kunomthamo wangaphambi kokugcinwa, kodwa ngemijikelo emininzi yokutshaja nokukhupha, ibhetri etshajwayo inokubuyiselwa kumthamo wayo ngaphambi kokugcinwa.

5. Iimpawu zobomi bomjikelo webhetri ye-NiMH.

Ubomi bomjikelo webhetri yeNiMH buchaphazeleka yinkqubo yokutshaja/yokukhupha, ubushushu kunye nendlela yokusebenzisa. Ngokwe-IEC standard charge and discharge, itshaja enye epheleleyo kunye nokukhupha yi-charge cycle yebhetri yeNiMH, kwaye imijikelo emininzi yokutshaja yenza ubomi bomjikelo, kwaye umjikelo wokutshaja kunye nokukhupha ibhetri yeNiMH ungadlula amaxesha angama-500.

6. Ukusebenza ngokukhuselekileyo kwebhetri ye-NiMH.

Ukusebenza ngokukhuselekileyo kweebhetri zeNiMH kungcono kuyilo lweebhetri ezinokutshajwa kwakhona, nto leyo ngokuqinisekileyo inxulumene nezinto ezisetyenziswa kwizinto zayo, kodwa ikwanolwalamano olusondeleyo nolwakhiwo lwayo.
