Isishwankathelo, imifuniselo yokuguga kunye nokufumanisa ukuguga kubaluleke kakhulu ukuqonda nokuvavanya ukusebenza kunye nobomi beebhetri ze-lithium-ion, ezinokusinceda siyile ngcono kwaye sisebenzise iibhetri kunye nokukhuthaza ukuphuhliswa kobuchwepheshe obuhambelanayo.
Zeziphi iinkqubo zovavanyo lokuguga kwebhetri ye-lithium kunye novavanyo lweprojekthi?
Ngokuvavanya kunye nokubeka iliso okuqhubekayo kwezi zenzo zilandelayo, sinokuqonda ngcono utshintsho kunye nokunciphisa ibhetri ngexesha lokusetyenziswa, kunye nokuthembeka, ubomi kunye neempawu zokusebenza kwebhetri phantsi kweemeko ezithile zokusebenza.
1. Ukuncipha kwamandla: Ukuncipha kwamandla sesinye sezibonakaliso eziphambili zokuhla kobomi bebhetri.Uvavanyo lokuguga luya kuthi ngamaxesha athile luqhube imijikelo yentlawulo kunye nokukhupha ukulinganisa umjikelo webhayisekile kunye nenkqubo yokukhupha ibhetri ekusetyenzisweni kokwenyani.Vavanya ukuthotywa kwamandla ebhetri ngokulinganisa utshintsho kumthamo webhetri emva komjikelo ngamnye.
2. Ubomi bomjikelo: Ubomi bomjikelo bubhekiselele ekubeni mingaphi na imijikelo epheleleyo yentlawulo kunye nokukhupha ibhetri enokuhamba kuyo.Imifuniselo yokuguga yenza inani elikhulu lentlawulo kunye nemijikelo yokukhupha ukuvavanya ubomi bomjikelezo webhetri.Ngokuqhelekileyo, ibhetri ithathwa njengefikelele esiphelweni sobomi bayo bomjikelo xa umthamo wayo ubola ukuya kwipesenti ethile yomthamo wayo wokuqala (umz., 80%).
3. Ukonyuka kokuchasana kwangaphakathi: Ukuchasana kwangaphakathi luphawu olubalulekileyo lwebhetri, oluchaphazela ngokuthe ngqo ukuhlawulwa kwebhetri kunye nokukhutshwa kakuhle kunye nokusebenza kakuhle kokuguqulwa kwamandla.Uvavanyo lokuguga luvavanya ukwanda kokuchasana kwangaphakathi kwebhetri ngokulinganisa utshintsho lokumelana kwangaphakathi kwebhetri ngexesha lokuhlawula kunye nokukhupha.
4. Ukusebenza kokhuseleko: Uvavanyo lokuguga lukwabandakanya ukuvavanywa kokusebenza kokhuseleko lwebhetri.Oku kunokubandakanya ukulinganisa indlela ibhetri esabela ngayo kunye nokuziphatha kwebhetri phantsi kweemeko ezingaqhelekanga ezifana nobushushu obuphezulu, ukutshajiswa kakhulu, kunye nokukhupha kakhulu ukubona ukhuseleko kunye nokuzinza kwebhetri phantsi kwezi meko.
5. Iimpawu zobushushu: Ubushushu bunempembelelo ebalulekileyo ekusebenzeni kwebhetri kunye nobomi.Imifuniselo yokuguga inokulinganisa ukusebenza kweebhetri phantsi kweemeko ezahlukeneyo zobushushu ukuvavanya impendulo yebhetri kunye nokusebenza kutshintsho lobushushu.
Kutheni ukuxhathisa kwangaphakathi kwebhetri kwanda emva kokusetyenziswa ixesha elithile?Iya kuba yintoni impembelelo?
Emva kokuba ibhetri isetyenziswe ixesha elide, ukuchasana kwangaphakathi kwanda ngenxa yokuguga kwezinto zebhetri kunye nesakhiwo.Ukuxhathisa kwangaphakathi kukuxhathisa okuhlangatyezwana nayo xa ikhoyo ngoku ihamba ngebhetri.Kuchongwa ngeempawu eziyinkimbinkimbi zendlela yangaphakathi yokuqhuba ibhetri eyenziwe nge-electrolytes, izinto ze-electrode, abaqokeleli bangoku, i-electrolytes, njl. Oku kulandelayo yimpembelelo yokwanda kokuchasana kwangaphakathi ekusebenzeni kakuhle kokukhupha:
1. Ukuhla kwamandla ombane: Ukuchasana kwangaphakathi kuya kubangela ukuba ibhetri ivelise i-voltage drop ngexesha lenkqubo yokukhupha.Oku kuthetha ukuba i-voltage yemveliso yokwenyani iya kuba ngaphantsi kombane wesekethe evulekileyo yebhetri, ngaloo ndlela inciphisa amandla akhoyo ebhetri.
2. Ukulahlekelwa kwamandla: Ukuchasana kwangaphakathi kuya kubangela ukuba ibhetri ivelise ubushushu obongezelelweyo ngexesha lokukhutshwa, kwaye obu bushushu bumele ukulahlekelwa kwamandla.Ilahleko yamandla inciphisa uguqulo lwamandla ebhetri, nto leyo ebangela ukuba ibhetri inikeze amandla anganeno asebenzayo phantsi kweemeko ezifanayo zokukhupha.
3. Ukunciphisa amandla okunciphisa amandla: Ngenxa yokunyuka kokuchasana kwangaphakathi, ibhetri iya kuba ne-voltage enkulu yokuhla kunye nokulahlekelwa kwamandla xa ukhupha umbane ophezulu, oya kubangela ukuba ibhetri ingakwazi ukubonelela ngokufanelekileyo umbane ophezulu.Ke ngoko, ukusebenza kakuhle kokukhupha kuncipha kwaye amandla ebhetri ayancipha.
Ngamafutshane, ukonyuka kokuchasana kwangaphakathi kuya kubangela ukukhutshwa kwebhetri ukuphumelela, ngaloo ndlela kuchaphazela amandla akhoyo ebhetri, ukuphuma kwamandla, kunye nokusebenza ngokubanzi.Ngoko ke, ukunciphisa ukuxhathisa kwangaphakathi kwebhetri kunokuphucula ukusebenza kakuhle kwebhetri kunye nokusebenza.
