Hona joale, ha ho sebelisoa likoloi tsohle tsa motlakase kapa tsa lebasetere, tsamaiso ea li-betri tsa lithium-ion li na le mathata a mangata, ho phaella ho lipotoloho tse sa laoleheng le tsa ho tjhaja le ho lahla, ho itšetlehile ka lintlha tsa polokeho, hoa hlokahala ho arola lipakete tsa betri ho fana ka li-voltages tse makholo. Pampiri ena e bua ka ho khetheha litlhoko tsa ho beha leihlo betri ea lithium ion, &39;me e bua ka likarolo tsa meralo le zero tse sebelisoang ke lits&39;ebetso tsa ho lekola betri, lits&39;ebetso tsa puisano tsa dijithale, le li-interfaces tsa ho itšehla thajana. Sistimi ea taolo, boto ea ho lekola betri e sebelisa lits&39;ebetso tse peli tsa bohlokoa ho lekola boemo ba betri ka ts&39;epahalo le ho fana ka liphetho tsa dijithale ho sistimi e kholo ea taolo e sebelisoang ke sistimi ea taolo, e le ho arola lits&39;ebetso tsena, ka li-circuits le liboto tse phahameng tsa li-betri.

Litšobotsi tsa betri tsa lithium-ion ha li tsamaellane le sistimi e rarahaneng ea elektroniki ea likoloi tsa motlakase ts&39;ebetsong, polokeho le litlhoko tsa ts&39;epo mme ntlha ena ka kotloloho ho tsoa ho litšoaneleho tsa betri ea lithium ion, thepa ea lithium e ntšoa, thepa ea lithium hangata e ionized ho anode ea graphite, ebe tsena lithium ion e tsamaisoa ke electrolyte ka electrolyte ho fihlela cathode ea cathode kaofela, &39;me cathode ea cathode e ka har&39;a cathode kaofela. e kgutlisetswang ke cathode ka searola. Ts&39;ebetso le ts&39;epahalo ea lenaneo lena la karabelo ea lik&39;hemik&39;hale li laoloa ke mocheso le motlakase oa yuniti ea betri. Ka mocheso o tlase, lik&39;hemik&39;hale tsa lik&39;hemik&39;hale li lieha, e le hore motlakase oa betri o fokotsehe, &39;me lebelo la ho arabela le eketseha ho fihlela lithium ha mocheso o ntse o eketseha, lebelo la ho arabela le eketseha ho fihlela lithium The ion unit e qala ho senyeha, ha mocheso o feta. 100°Ha C, electrolyte e qala ho hlahloba, ho lokolloa ha khase e ka &39;nang ea baka khatello ea lisele tsa betri ka moralo, ka mocheso o phahameng, lithium ion battery unit e ka lokolla oksijene ka lebaka la tlhahlobo ea oxide sefahlehong sa mocheso o sa laoleheng, ho feta Ho potlakisa ho phahama ha mocheso.

Ka hona, maemo a molemo ka ho fetisisa a ho sebetsa bakeng sa ho boloka betri ea lithium ion ke tlhokahalo ea bohlokoa ea tsamaiso ea betri. Phephetso ea bohlokoa ha ho etsoa litsamaiso tsa taolo le taolo ke ho netefatsa ho fumana lintlha tse tšepahalang le ho bola ho lekola boemo ba libeteri tsa lithium-ion ka koloing. Hona ke bothata bo ikhethang ba betri ea lithium ion ka boeona.

Ka koloing ea motlakase ea ChevyVolt, pakete ea betri e na le libeteri tse 288 tsa lithium-ion tse 288, tse arotsoeng ka lipakete tsa betri tse 96, &39;me li fana ka li-voltages tsa sistimi ea 386.6V DC, tse etsang libeteri tse &39;ne tse kholo hammoho le li-sensor tsa mocheso le likarolo tse futhumatsang. Mojule, mohala oa ho utloa ha motlakase o hokahantsoeng sehlopheng se seng le se seng sa betri o hokahantsoe le mojule o mong le o mong oa betri, &39;me terminal e rarolloa ebe e hokahantsoe le module ea segokanyimmediamentsi sa betri ka holim&39;a mojule o mong le o mong oa betri ka sehokelo se kopaneng sa voltage sensing sehokelo, 4 se sebelisa mmala.
