Ibango lezikhuselo ezinde liqhuba uphuhliso lweebhetri ezomeleleyo, ezinamandla zesixhobo semizi-mveliso, izixhobo zangaphandle, kunye nezithuthi zombane. Isikhundla esiphakamileyo iibhetri ze-lithium-ion inokunceda kakhulu ishishini lakho. Makhe siphonononge izinto eziphambili ezikhoyo namhlanje.
Kutheni imicimbi yebhetri
Umthamo webhetri, olinganiswe kwii-milliamp-iiyure (Mah), ibonisa ukuba isixhobo sisebenza ixesha elingakanani ngaphambi kokufuna ukutshata; I-Mah ephezulu ithetha ukusetyenziswa ixesha elide.
Cinga nge-mah njengobukhulu betanki yamafutha – Iitanki ezinkulu zivumela i-rings ende phakathi kwendawo yezalisa. Umzekelo, ibhetri engama-5000 ye-5000 ye-5000 ingenza i-5000 yeemilmampops zeyure enye okanye i-1000 yee-milliamps iiyure ezintlanu.
Ibhetri ye-Lithium-i-Ion-Iyon ye-Iyon-ion ibonelela ngezibonelelo eziphambili, ezinje:
- Ixesha elide lokuhamba kwexesha ngexesha lemisebenzi efana nenkampu okanye isebenzisa izixhobo ezingenakomkhethi.
- Ukunciphisa ukutshata okungakumbi, Yandisa ubomi bebhetri ngenxa yemijikelezo emincinci yokutshaja.
- Ukuphuculwa kwentsebenzo kwizixhobo eziphezulu zokuhamba ezifana nezixhobo zombane kunye neebhayisikile, ukuthintela ukulahleka kwamandla kwangoko.
Umthamo ophezulu: 18650 vs. 21700 ibhetri
Okwangoku, i-18650 kunye nama-21700 yeyona i-lelium ethandwayo ye-lithium-ion yebhetri kwintengiso.
I-18650: Umthamo oqinisekileyo oqinisekileyo
Ibhetri ye-18650 lukhetho oluhle kakhulu lweeseli ze-lithium ezinokuphinda zisebenze.

I-FAQs malunga nebhetri ye-Lithium ye-Ion ye-Ion
Zingaphi ii-cycles ezinokubangela ukuba ibhetri ephezulu ye-18650?
Imijikelezo ehlawulayo ixhomekeke kumgangatho webhetri, ukusetyenziswa, kunye ubunzulu bokukhutshwa. Umgangatho ophezulu we-18650 ubonelela nge-300-500 i-300-500 i-300-500 i-500-500 i-800-500 ihlawulwe ngokupheleleyo ngaphambi kokulahlekelwa kwento ebalulekileyo, kunye neendlela ezithile zepremiyamu ezibangwa ukuya kuthi ga kwi-1000 imijikelezo.
I “Umthamo ophezulu = ngcono” ihlala iyinyani?
Ibhetri ye-Lithium ayinakwenziwa kuphela ngumthamo, njengoko isicelo ngasinye sineemfuno ezizodwa. Ibhetri ebalaseleyo ngulowo uhlangabezana nezidingo ezithile.
Ndingaphucula ngokukhuselekileyo kwiibhetri eziphezulu zexabiso?
Kuphela phantsi kweemeko ezingqongqo ngokungqongqo kuphela:
- Izixhobo ezisebenzisa iiseli ezinokutshintshwa ngumsebenzisi (E.G., izibane, izixhobo ezithile zamandla)
- Iiseli ezintsha zine-cd / i-cdr ephezulu kunezinto zokuqala
- Umdlalo wemigangatho yomzimba ngaphakathi kwe-0.1MMM
Ungaze uzame:
- Iipakethi zebhetri ezenziwe ngebhetri (i-BMS yokungaphumeleli)
- Izixhobo zokuzoba ngaphezulu kwe-10A (ifuna ubunjineli benqanaba lepakethi)
- Izixhobo zonyango okanye zokuhamba
Ngaba iibhetri eziphakamileyo zexabiso eliphezulu?
Isantya sokutshaja sixhomekeke kwi Ireyithi ye-C, hayi amandla.
