Ho Utulla Bohlokoa ba Boto ea Tšireletso ea Battery ea Lithium

Libetri tsa lithium li tumme ka matla a tsona a phahameng a matla, e leng se etsang hore e be tse loketseng ho matlafatsa mefuta e mengata ea lisebelisoa tsa elektroniki. Leha ho le joalo, k'hemistri ea bona ka tlhaho ha e tsitsa, e ba etsa hore ba senyehe habonolo ka lebaka la ho tjhaja ho feta tekano, ho tsoa ho feta tekano, le ho tsoa ka potlako. Ho fokotsa likotsi tsena le ho netefatsa ts'ebetso e nepahetseng le polokeho, libeteri tsa lithium li hloka sistimi e matla ea ts'ireletso. Tataiso ena e hlahloba mekhoa e rarahaneng ea mapolanka a tšireletso ea betri ea lithium le mekhoa ea tsamaiso ea betri (BMS), e totobatsang moralo oa bona, ts'ebetso le bohlokoa ba lisebelisoa tsa elektronike tsa morao-rao.

Boto ea tšireletso ea betri ea lithium ke sesebelisoa se amanang le polokeho, kahoo litsela tsa hona joale tsa MOSFET, ho phahama ha mocheso, le tšireletso ea liphoso li lokela ho hlahlojoa ho nahanoa ka tšireletso ea ho phahama ha motlakase oa PCB le ho netefatsoa ka liteko tsa motlakase.

Ho utloisisa Maboto a Tšireletso ea Battery Lithium

Liboto tsa ts'ireletso ea betri ea lithium li bapala karolo ea bohlokoa ho netefatsa ts'ebetso e bolokehileng le e ts'epahalang ea libeteri tsa lithium. Liboto tsena li sebetsa e le tšireletso khahlanong le mefuta e mengata ea likotsi tse ka senyang ts'ebetso ea betri, bophelo bo bolelele le polokeho. Har'a litšokelo tsa mantlha tseo liboto tsa ts'ireletso li itebelang khahlanong le tsona ke ho tjhaja ho feta tekano, ho chacha ho feta tekano, le litefiso tse fetelletseng tsa ho tsoa, ​​e 'ngoe le e 'ngoe ea tsona e ka bakang tšenyo e kholo kapa esita le ho se sebetse ho hoholo ha betri.

Liboto tsa ts'ireletso ke likopano tse tsoetseng pele tse nang le likarolo tse fapaneng tsa elektroniki, e 'ngoe le e' ngoe e kenya letsoho tšebetsong eohle le katlehong ea sistimi. Likarolo tsa bohlokoa tse fumanehang ka har'a liboto tsa ts'ireletso li kenyelletsa li-circuits (ICs), li-switch tsa metal-oxide semiconductor (MOS), li-capacitor, li-resistors, li-thermistor tse mpe tsa mocheso (NTCs), li-coefficient thermistors (PTCs), li-module tsa memori, boitsebahatso (ID) li-circuits, le lisebelisoa tse ling tse thusang.
