I-Chemistry oyikhethayo itshintsha i-BMS oyidingayo
Kwiphakheji yokugcina amandla, ikhemistri yeseli igqiba ngaphezu koxinano lwamandla kunye neendleko - ibeka ifestile yevolthi, inani leeseli ezilandelelanayo, kunye nemida yokhuseleko ekufuneka isetyenziswe yinkqubo yolawulo lwebhetri (i-BMS). Esi sikhokelo sithelekisa iikhemistri ezine ezisetyenziswa kwindawo yokugcina - iLiFePO4 (LFP), iNMC (i-nickel manganese cobalt), iLTO (i-lithium titanate), kunye nesodium-ion - kunye nokuba ithetha ukuthini nganye xa ukhetha iBMS. Ukuze ufumane amanyathelo apheleleyo okukhetha iBMS, qala kwiIsikhokelo sokukhetha i-BMS.
IiKhemistri Ezine Ngokujonga Nje
Itheyibhile ibonisaummeliamaxabiso — amanani okwenyani ayahluka ngokwabenzi kunye neseli, ngoko ke qinisekisa i-datasheet yeseli yakho.

Amaxabiso amele ukuthelekisa kuphela; qinisekisa i-datasheet yomthengisi weseli yakho ukuze ufumane imida yokwenyani.
Indlela Yokucinga Ngokhetho
I-LiFePO4— yindlela emiselweyo yokugcina izinto ezininzi ekhaya nakwiindawo zorhwebo.
Ulungelelwano oluqinileyo lokhuseleko, ubomi bomjikelo omde, kunye neendleko. Ukuba awunasizathu sokukhetha ngenye indlela, iLiFePO4 idla ngokuba yindawo yokuqala.
I-NMC— xa uxinano lwamandla kunye nokuxinana kubaluleke kakhulu.
Ubuninzi bamandla kwipakethi encinci, ekhaphukhaphu, ngexabiso lemijikelo embalwa kunye nolawulo oluqinileyo lobushushu.
I-LTO— ubomi bomjikelo ogqithisileyo, ukutshaja ngokukhawuleza, kunye namaqondo obushushu abanzi.
Ukhetho olukhethekileyo kodwa oluhlala ixesha elide apho ubomi obude kunye nobushushu bungaphezulu kobuninzi bamandla. →Ukukhetha i-BMS ye-LTO.
I-sodium-ion— ukhetho oluvelayo lwemozulu ebandayo kunye nokubonelela ngokwahlukahluka.
Ukuziphatha okuthembisayo kobushushu obuphantsi kunye noluhlu olwahlukileyo lobonelelo, kunye nenkqubo yendalo ephuhlisayo. →Ukukhetha i-BMS ye-sodium-ion.
Oko Kuthethwa YiKhemistri Nganye kwi-BMS
Nokuba yeyiphi na ikhemistri oyikhethayo, i-BMS kufuneka ilungiselelwe yona:
Imida yokhuseleko.
Imida ye-over-voltage, i-under-voltage, kunye ne-balancing yahlukile ngokwekhemistri — iseti ye-BMS yekhemistri enye iya kuyikhusela kakubi enye.
Inani leechungechunge.
Ngenxa yokuba i-voltage yeseli eqhelekileyo yahlukile, inani leeseli ezilandelelanayo ze-voltage yephakheji ekujoliswe kuyo liyatshintsha — i-LTO ifuna uninzi lweeseli, i-NMC incinci, kwi-voltage efanayo.
Uqikelelo lwemali ehlawulwayo.
I-SOC ifundwa kwi-voltage curve yekhemistri; ukusebenzisa i-curve engalunganga kuxela inqanaba lokutshaja elingalunganga.
I-DALY: Iqabane elinye le-BMS kuzo zonke iiKhemistri ezine
I-DALY ivelisa iinkqubo zolawulo lweebhetri ze-I-LiFePO4, i-NMC, i-LTO, kunye ne-sodium-ion. Imida yokhuseleko, inani lothotho, uqikelelo lwemeko yentlawulo, kunye nokulinganisela kulungiselelwe iseli yakho ethile - ukuze ukwazi ukwenza iqabane elinye le-BMS libe semgangathweni kwiikhemistri ezahlukeneyo. Thumela iphepha ledatha leseli yakho kunye noyilo lwepakethi, kwaye iqela lobunjineli le-DALY liya kuqinisekisa uqwalaselo oluchanekileyo lwekhemistri oyikhethileyo.
Imibuzo ebuzwa qho
Q1Yeyiphi ikhemistri efanelekileyo yokugcina ilanga ekhaya?
I-LiFePO4 yeyona ndlela iphambili yokulinganisela ukhuseleko lwayo, ubomi bomjikelo, kunye neendleko. I-NMC, i-LTO, kunye ne-sodium-ion zihambelana nezinto eziphambili - ubuncinci, ixesha elide/ubushushu obugqithisileyo, okanye imozulu ebandayo kwaye inikezela ngokwahlukahluka.
Q2Ngaba i-BMS enye ingaphatha iikhemistri ezahlukeneyo?
I-BMS kufuneka ilungiselelwe ikhemistri ethile — imida yayo, inani lothotho, kunye ne-SOC curve. Umthengisi ofanayo unokubonelela nge-BMS kwiikhemistri ezahlukeneyo, kodwa i-BMS yephakheji nganye imiselwe iiseli zayo.
Q3Kutheni ikhemistri itshintsha inani leeseli ezilandelelanayo?
Ikhemistri nganye ine-voltage yeseli eyahlukileyo, ngoko ke ukufikelela kwi-voltage yephakheji ekujoliswe kuyo kuthatha inani elahlukileyo leeseli - umzekelo i-LTO (~2.3V) ifuna iiseli ezingaphezulu kune-LiFePO4 (~3.2V) kwi-voltage efanayo.
