Emva kokuthenga uhlobo oluthile lweshaja, abaninzi bajamelene neengxaki zendlela yokuyilayisha ngokufanelekileyo? Enye yezona ntlobo eziphambili yi-nickel-metal hydride (NiMh) ibhetri. Banobuqhetseba babo bokuzihlawulisa.
Indlela yokuhlawula ngokufanelekileyo ithethri ye-NiMh?
Ubungqayizivele betshethi ye-NiMh bubungqina babo ukutshisa nokugqithisa. Oku kungakhokelela kwimiphumo emibi echaphazela amandla okufowuna ukuba abambe kwaye ahambise intlawulo.
Phantse onke amabhetri alolu hlobo asebenzise indlela "ye-delta" (ukugqiba ukuphakama kombane wokutshaja). Ikuvumela ukuba ubonise ukuphela kwesawulo. Ipropati yeeshaja ze-nickel kukuba i-voltage ye-battery ye-NiMh ehlawulelwayo iqala ukunciphisa inani elincinci.
Indlela yokuhlawula ibhetri ye-NiMh?
Indlela ye "delta peak" iyakwazi ukusebenza kakuhle kunye neengcingo zee-0.3C okanye ngaphezulu. Ixabiso le C lisetyenziselwa ukubonisa amandla okutyunjwa kwe-rechargeable aa ni NiBh ibhetri.
Ngaloo ndlela, kwi-charger ye-1500 mAh, indlela ye-delta yeyona ndlela iya kusebenza ngokuthe ngqo ngexabiso elingaphantsi kwe-0.3x1500 = 450 mA (0.5 A). Ukuba okwangoku kuxabiso elisezantsi, kukho ingozi enkulu yokuba ekupheleni komrhumo, umbane kwibhetri awunakuqala ukuhla, kwaye uya kuxhoma kwinqanaba elithile. Oku kuya kubangela ukuba ishaja ingaboni ukuphela kwesawulo. Ngenxa yoko, akusayi kubakho ukunqumla kunye nokuqhubeka nokulayishwa kwakhona. Umthamo webhethri uya kuncipha, oya kuphazamisa ukusebenza kwawo.
Okwangoku, phantse zonke iishaja zihlawulwa zifike kwi-1C. Kule meko,
Ukwandisa ubomi beshaja ye-nickel-metal hydride, unokuyincoma ukuba uyigcine ngexabiso elingabalulekanga (30-50%).
Ngaloo ndlela, ukuhlawulwa ngokuchanekileyo kwebhetri ye-nickel-metal hydride kuya kuthintela ukusebenza kwayo kwaye kukunceda ukuba isebenze ngokuqhelekileyo.
