Ngemva kokuthenga uhlobo oluthile lweshaja, abaningi babhekana nenkinga yokuyilayisha kahle? Enye yezinhlobo eziyinhloko yi-nickel-metal hydride (NiMh) amabhethri. Banobuchwepheshe babo bokuzikhokhela.
Ungayishaja kanjani kahle ibhethri ye-NiMh?
Ubungqayizivele bamabhethri e-NiMh ukuzwela kwabo ukushisa nokugqithisa. Lokhu kungaholela emiphumeleni emibi ephazamisa ikhono le-device ukubamba nokuletha inkokhelo.
Cishe wonke amabhethri alolu hlobo asebenzisa indlela "ye-delta" (ekunqumeni ukuphakama komthamo wokushaja). Ikuvumela ukuba ubonise ukuphela kokushaja. Impahla yamashaja we-nickel wukuthi amavolumu webhethri ye-NiMh ekhokhiswayo aqala ukwehla ngesamba esithile esingabalulekile.
Ungashaja kanjani ibhethri ye-NiMh?
Indlela "ye-delta" ikwazi ukusebenza kahle ngezingcingo zokukhokhiswa ze-0.3C noma ngaphezulu. Inani le C lisetshenziselwa ukukhombisa amandla okuqokwa kwebhethri ye-NiMh ekhokhelwa kabusha.
Ngakho-ke, ngomshini we-1500 mAh, indlela ye-delta ye-peak izosebenza ngokuthembekile ngezindleko ezincane zamanje ezingu-0.3x1500 = 450 mA (0.5 A). Uma okwamanje kunenani eliphansi, kukhona ingozi enkulu ukuthi ekupheleni kokushaja, i-voltage ebhethri ngeke iqale ukwehla, futhi izolenga ezingeni elithile. Lokhu kuzokwenza ukuthi ishaja ingaboni ukuphela kokushaja. Ngenxa yalokho, ngeke kube khona ukuxhumeka nokuqhubeka nokulayisha kabusha. Umthamo webhethri uzokwehla, okuzokwenza ukuthi kuthinte ukusebenza kwawo.
Njengamanje, cishe wonke amashaja angakhokhiswa ku-1C. Kulokhu,
Ukwandisa impilo yeshaja yensimbi ye-nickel-metal, ungancoma ukuyigcina ngenani elingakahle lokukhokha (30-50%).
Ngakho-ke, ukushaja okulungile kwebhethri ye-nickel-metal kuyothatha ukusebenza kwayo futhi kusize ukuthi isebenze ngendlela evamile.
