Yintoni ireyithi yokukhupha?

Ndikolu shishino iminyaka elishumi elinesibini ngoku. Usafumana iminxeba evela kubaphathi abathengayo abathenge iiseli ezingezizo kwisicelo sabo. Kwinyanga ephelileyo umfana uye waodola iiseli ze-5000 ze-Samsung 35E ze-e{4} yezithuthi zebhayisekile. Umthamo omkhulu, 3500mAh, ixabiso elihle. Ingxaki kukuba ezo seli zibekwe i-8A ngokuqhubekayo. Iibhayisekile zakhe zitsala i-25A ezintabeni. Kwiiveki ezintathu emva koko isiqingatha sepakethe yakhe siyadumba.

Ireyithi yokukhupha. Nantso into ayiphosileyo.

Abavelisi izinga lokukhupha amandla kwi-C. Iseli ye-3000mAh kwi-1C ithetha ukuba i-3A idonsa ngokuqhubekayo. Iseli enye ku-5C ithetha i-15A. Izibalo zithe ngqo kodwa esona sicelo{8}sehlabathi sikhwelisa abantu rhoqo.

Nantsi into ekungekho mntu ukuxelela yona kwi-database. Laa C-kalo? Ivavanywa kwiqondo le-25 kwigumbi lemozulu elinonxibelelwano olugqibeleleyo lobushushu. Ipakethi yakho ehleli kwindawo ebiyelweyo yentsimbi ehlotyeni yase-Arizona ayizukulingana naloo manani. Ndikhe ndabona iiseli ze-Molicel P28A ezilinganiswe nge-35A zehla ukuya mhlawumbi kwi-25A ekhuselekileyo eqhubekayo xa ujonga iimeko zokwenyani zobushushu. Iiseli ezibalaseleyo. Hayi nje umlingo.

Imakethi ye-18650 iye yazinza kwimigangatho ngoku. Unayo i-Sony VTC5A yakho, i-Molicel P26A, i-Samsung 25R yokukhupha amanzi aphezulu. I-LG HG2 kunye ne-Samsung 30Q zihlala phakathi. I-Samsung 35E kunye neeseli ze-Panasonic/Sanyo NCR zomthamo. Ukudibanisa ezi zinto kubangela iingxaki. Ndiyibonile isenzeka ngokuphindaphindiweyo.

UMilwaukee kunye noDeWalt abazange bayiqonde le nto ngobusuku nje. Iipakethi zesixhobo ze-lithium zakwangoko zasebenzisa naziphi na iiseli{1} zomthamo ophezulu ebezikhona. Abasebenzisi bakhalaze nge-sag phantsi komthwalo. Izixhobo zaziva zibuthathaka xa zithelekiswa neepakethe ze-NiCd ezindala ezinokulahla okwangoku imini yonke.

Ngoku ii-brand ezinkulu zixela iiseli zazo. I-Milwaukee isebenzisa iiseli zesiko eziphezulu{1}}ezingenako nokuzithenga uninzi lwethu. UDeWalt uhambe ngendlela eyahlukileyo, iiseli zefomati ezinkulu ezinobunzima obungcono bobushushu. UMakita uye wahlala iminyaka, nto leyo eyinxalenye yesizathu sokuba izixhobo zabo ze-18V zizive ziphantsi kwamandla kude kube mva nje.

Imakethi ye-knockoff pack yintlekele ngenxa yesi sizathu. Ezo pakethi zokutshintsha zitshiphu kwiAmazon? Isiqingatha sabo sisebenzisa iiseli zelaptop ezihlaziyiweyo{1}}iiseli ezikalwe ngu-C kwisixhobo esifuna i-8C. Isebenza kakuhle kumsebenzi olula. Yibeke phantsi komthwalo wangempela kwaye ujonge umlilo ekugqibeleni.

Uluntu lwe-hobbyist lufumene amanqaku okukhutshwa kwiminyaka engamashumi amabini eyadlulayo. Iiforam zeRC zinolwazi oluthe kratya lwebhetri kunamasebe amaninzi obunjineli endikhe ndasebenza nawo. Aba bafo batyhala iiseli kwimida epheleleyo kwaye babelane ngeziphumo.

I-5000mAh 6S lipo kwi-50C inokuthi ikhuphe i-250A. Akukho mntu utsala oko ngokuqhubekayo kodwa ugqabhuko lwamanqaku lubalulekile ukubhabha nge-acrobatic. Into ehlekisayo kukuba uninzi lwabaqhubi abasajongi nokujonga C-ukalisho kwakhona. Bajonga ukuchasana kwangaphakathi. Ipakethi ene-2mΩ kwiseli nganye iyakugqwesa ipakethe ene-5mΩ nokuba ithini na ileyibhile.

Turnigy, Tattu, CNHL, Goldbat. Isidima sebhrendi sibaluleke ngaphezu kokucaciswa kwesi sithuba kuba iinkcazo zihlala zixoka. Ndivavanye iipakethi ezibhalwe 100C ezingakwaziyo ukugcina i-30C ngaphandle kwe-voltage sag. Abavelisi baseTshayina badlala imidlalo ngokulinganisa rhoqo.

Ii-electrode ezinqabileyo zithetha ukunyakaza kwe-ion ngokukhawuleza. Ukunyakaza kwe-ion ngokukhawuleza kuthetha amazinga aphezulu okukhupha. Kodwa i-electrode ezincinci zibamba izinto ezincinci ezisebenzayo. Izinto ezisebenza ngaphantsi zithetha umthamo ophantsi.

Lulo ke urhwebo olusisiseko. Akukho chemistry ijikelezayo. Xa umntu ebanga ukuba uneseli enesakhono esiphezulu kunye nokukhutshwa okuphezulu, usebenzisa ifomathi enkulu okanye uyaxoka.

I-Cobalt-i-cathodes enzima njenge-NCA ikunika umthamo. I-Manganese{2}}i-cathodes enzima njenge-NMC ikunika amandla. Ikhemistri ye-LFP iphatha kakubi kakuhle kodwa ukuxinana kwamandla kuyabandezeleka. Yonke iseli yi-compromise. Ubugcisa bungqamanisa oko kulalanisa kwisicelo sakho.

Iiseli zesingxobo kwiindawo ezinjenge-Amprius kunye ne-Enovix zityhala imida nge-silicon anodes. Amanani omthamo achukumisayo. Kodwa i-silicon iyadumba ngexesha lokuhamba ngebhayisikile. Ixesha elide eliphezulu{3}idatha yokusebenza kombhobho isenomda. Ndibukele esi sithuba kodwa andibheji imigca yemveliso kuyo okwangoku.

Iseli elinganiswe nge-10C kwi-25℃ingaphatha kuphela i-5C kwi-45℃ngaphambi kokuba uqale ukuyonakalisa. Kubanda kubi. Zama ukutsala i-20A kwiseli kwi-10℃kwaye ubukele ukuba kwenzekani. Iikhreyitha zombane. Izikhukula zangaphakathi zokuchasa. Ungafumana isiqingatha somthamo olinganisiweyo.

Kungenxa yoko iipakethi zeTesla zineenkqubo zokupholisa kunye nokufudumeza. Iiseli zabo azikhethekileyo. Ulawulo lwe-thermal yinto ebavumela ukuba babethe la manani amandla rhoqo. Iipakethe zamagqabi zonakaliswe ngokukhawuleza kwimozulu eshushu kangangeminyaka ngenxa yokuba iNissan yakhawuleza yapholisa. Iiseli ezifanayo, iziphumo ezahlukeneyo.

Uyilo lwepakethi lubalulekile njengokukhetha iiseli. Ndibone iiseli ezinkulu zonakaliswe luyilo olubi lwebhasi edale iindawo ezishushu. Ndibone iiseli eziphakathi zisebenza kakuhle kuba uyilo lwepakethi ye-thermal lwaluhlakaniphile.

Yazi isicelo sakho. Yazi iprofayile yakho yomthwalo. Emva koko khetha iiseli ezihambelana nomda oseleyo. I-Samsung 30Q ilungile kulaa -bhayisekile ukuba uhamba ngeendlela ezisicaba ngo-15A. Ayilunganga loo nduli{7}}yokukhwela ibhayisekile yempahla itsala 40A ukugqabhuka.

Amaphepha athile abalisa inxalenye yebali. Uvavanyo oluzimeleyo oluvela kwiindawo ezinjengeBattery Mooch ixela ngakumbi. Olona vavanyo lwepakethi phantsi kweemeko zakho ezithile luxela okuseleyo.

Fowunela umthengisi weeseli zakho. Cela ukukhupha iigophe kumaqondo obushushu amaninzi. Ukuba abakwazi ukubabonelela, fumana umboneleli owahlukileyo. Olu ayiselulo ulwazi lokuzikhethela. Iipakethi ezininzi aziphumelelanga kuba umntu utsibe eli nyathelo.
