Kukho iimpawu ezintandathu eziphambili zeIibhetri zeNiMH. Iimpawu zokuhlawula kunye neempawu zokukhupha ezibonisa ubukhulu becala iimpawu zokusebenza, iimpawu zokuzikhupha kunye neempawu zokugcinwa kwexesha elide ezibonisa ngokukodwa iimpawu zokugcina, kunye neempawu zobomi bomjikelezo kunye neempawu zokhuseleko ezibonisa ngokuyintloko ezidibeneyo. Zonke zigqitywe ngesakhiwo sebhetri ehlaziywayo, ngokukodwa kwindawo ehlala kuyo, kunye neempawu ezicacileyo zokuchatshazelwa ngokungenakulinganiswa kwiqondo lokushisa kunye nokukhoyo. Oku kulandelayo kunye nathi ukujonga iimpawu zebhetri ye-NiMH.

1. Iimpawu zokutshaja iibhetri zeNiMH.

Xa iIbhetri yeNiMHukonyuka kwangoku kokutshaja kunye (okanye) ukuhla kweqondo lobushushu lokutshaja kuya kubangela ukuba amandla ombane wokutshaja anyuke. Ngokubanzi kwiqondo lobushushu eliphakathi kwe-0 ℃ ~ 40 ℃ kusetyenziswa intlawulo yangoku engaguqukiyo engekho ngaphezulu kwe-1C, ngelixa ukutshaja phakathi kwe-10 ℃ ~ 30 ℃ kunokufumana ukutshaja okusebenzayo.

Ukuba ibhetri isoloko ihlawuliswa kwindawo yobushushu obuphezulu okanye obuphantsi, iya kubangela ukucutheka kokusebenza kwebhetri yamandla. Ukutshaja ngokukhawuleza ngaphezulu kwe-0.3C, amanyathelo olawulo lokutshaja ayimfuneko. Ukutshaja ngokuphindaphindiweyo kuya kunciphisa ukusebenza kwebhetri ehlaziywayo, ngoko ke, amaqondo okushisa aphezulu kunye aphantsi kunye nemilinganiselo yokukhusela yokutshaja ngokuphezulu kufuneka ibe khona.

2. Iimpawu zokukhutshwa kweebhetri ze-NiMH.

Iqonga lokukhupha leIbhetri yeNiMHyi 1.2V. Iphezulu yangoku kunye neqondo lokushisa eliphantsi, i-voltage ephantsi yokukhupha kunye nokusebenza kakuhle kwebhetri ehlaziywayo iya kuba, kwaye ubuninzi obuqhubekayo bokukhutshwa kwebhetri etshajwayo yi-3C.

Ukukhutshwa kwe-voltage ye-discharge cut-off yebhetri etshajwayo ngokuqhelekileyo ibekwe kwi-0.9V, kwaye i-IEC standard charge / mode discharge ibekwe kwi-1.0V, kuba, ngaphantsi kwe-1.0V, umbane ozinzileyo unokubonelelwa ngokubanzi, kwaye ngaphantsi kwe-0.9V kancinci. incinci yangoku inokubonelelwa, ngoko ke, ukuchithwa kwe-voltage yokunqunyulwa kweebhetri ze-NiMH kunokuthathwa njengoluhlu lwe-voltage ukusuka kwi-0.9V ukuya kwi-1.0V, kwaye ezinye iibhetri ezinokutshajwa kwakhona zingabhaliswa kwi-0.8V. Ngokubanzi, ukuba i-voltage yokunqunyulwa ibekwe phezulu kakhulu, umthamo webhetri awukwazi ukusetyenziswa ngokupheleleyo, kwaye ngokuchaseneyo, kulula kakhulu ukubangela ukuba ibhetri ehlawulelwayo ikhuphe ngaphezulu.

3. Iimpawu zokuzikhupha kwiibhetri ze-NiMH.

Ibhekisa kwinto yokulahleka komthamo xa ibhetri etshajwayo igcwaliswe ngokupheleleyo kwaye igcinwe isekethe evulekileyo. Iimpawu zokuzikhupha zichatshazelwa kakhulu ngubushushu be-ambient, kwaye ukuphakama kweqondo lokushisa, kukhulu ukulahleka kwamandla ebhetri etshajwayo emva kokugcinwa.

4. Iimpawu zexesha elide zokugcina iibhetri zeNiMH.

Isitshixo kukukwazi ukubuyisela amandla eebhetri ze-NiMH. Ngexesha elide lexesha (elifana nonyaka) xa lisetyenziswa emva kokugcinwa, umthamo webhetri etshajwayo unokuba mncinci kunomthamo ngaphambi kokugcinwa, kodwa ngemijikelo emininzi yokutshaja nokukhupha, ibhetri egcwalisekayo inokubuyiselwa kumthamo ngaphambili. yokugcina.

5. Iimpawu zobomi bebhetri ye-NiMH.

Ubomi bomjikelezo webhetri ye-NiMH buchaphazeleka yinkqubo yokuhlawula / yokukhupha, ubushushu kunye nendlela yokusebenzisa. Ngokwe-IEC intlawulo esemgangathweni kunye nokukhutshwa, enye intlawulo epheleleyo kunye nokukhutshwa ngumjikelo wentlawulo yebhetri ye-NiMH, kwaye imijikelezo emininzi yentlawulo yenza ubomi bomjikelezo, kwaye umjikelo wentlawulo kunye nokukhutshwa kwebhetri ye-NiMH unokudlula amaxesha angama-500.

6. Ukusebenza kokhuseleko lwebhetri ye-NiMH.

Ukusebenza kokhuseleko lweebhetri ze-NiMH kubhetele kuyilo lweebhetri ezinokutsha, ngokuqinisekileyo zihambelana nezinto ezisetyenziswe kwizinto zayo, kodwa zinobudlelwane obusondeleyo kunye nesakhiwo sayo.
