Ho boloka matla a likoloi tsa motlakase tse tsamaeang ho kengoa ts'ebetsong joang

Polokelo ea matla ea likoloi tse tsamaeang ka matlae fumaneha haholo ka libeteri. Betri ke sesebelisoa se fetolang matla a lik'hemik'hale hore e be matla a motlakase, ao a atileng haholo ke betri ea lithium-ion.

Libetri tsa lithium-ion tse sebelisoang likoloing tse tsamaeang ka matla hangata li entsoe ka lisele tse ngata. Sele e 'ngoe le e' ngoe e hokahane ke searohano se phuthetsoeng ka lisebelisoa tse ntle le tse mpe. Lisebelisoa tsa cathode hangata li sebelisa li-oxides, tse kang lithium cobalt oxide, lithium manganate, joalo-joalo, le lisebelisoa tse mpe tsa electrode hangata li sebelisa graphite.

Ts'ebetso ea ho boloka matla ea libeteri tsa lithium-ion e ka aroloa feela ka mekhahlelo e 'meli: ho tjhaja le ho tjhaja. Ha o tjhaja, mohloli oa matla o fetisa motlakase ka electrode e ntle ea betri, e leng se etsang hore li-ion tsa lithium li suthele pakeng tsa li-electrode tse ntle le tse mpe. Ka nako ena, li-ion tsa lithium li tloha ho electrode e ntle, li fetisetsoa ho electrode e mpe ka li-ion tse ka har'a electrolyte, 'me li kenngoa ka graphite ea lisebelisoa tse mpe tsa electrode. Ka nako e ts'oanang, li-ion tse ntle ka har'a electrolyte ka betri li boetse li falla ho boloka ho se nke lehlakore ha motlakase pakeng tsa li-electrode.

Ha matla a motlakase a bolokiloeng a hlokahala, hona joale ho kena mochine ho tloha ho electrode e mpe, 'me li-ion tsa lithium li tsamaea ka tsela e fapaneng ho tloha ho electrode e mpe ho ea ho electrolyte pakeng tsa li-electrode tse ntle ebe li khutlela ho lisebelisoa tse ntle tsa electrode. Nakong ea ts'ebetso ena, ho sisinyeha ha li-ion tsa lithium ho baka ho phalla ha motlakase le ho lokolla matla a motlakase a bolokiloeng.

Sebaka sa polokelo ea matla a betri ea likoloi tse tsamaeang ka matla le tsona li hloka ho ela hloko matšoao a bohlokoa, joalo ka matla a betri le voltage. Bokhoni bo bolela matla a motlakase ao betri ea lithium-ion e ka e bolokang le ho e lokolla, eo hangata e lekantsoeng ka lihora tsa ampere (Ah). Voltage ke phapang e ka bang teng ea matla a motlakase a betri ea lithium-ion. Ka kakaretso, motlakase oa DC o sebelisoa, joalo ka 3.7V, 7.4V, joalo-joalo.

Likoloi tse tsamaeang ka matla, e le ho finyella ho boloka matla le ho lahla matla, tšehetso ea tsamaiso ea betri (BMS) e boetse e hlokahala. BMS ke sesebelisoa se ikarabellang bakeng sa ho lekola le ho laola pakete ea betri, e ka netefatsang polokeho ea betri, ho lelefatsa bophelo ba eona le ho ntlafatsa ts'ebetso ea matla a matla.

BMS haholo-holo e kenyelletsa lisensara tsa mocheso, li-sensor tsa hajoale, li-voltage sensors le li-control chips. Sensor ea mocheso e sebelisetsoa ho shebella mocheso oa betri pakete ho qoba ho chesa kapa ho feta; sensor ea hona joale e sebelisetsoa ho lemoha tefiso le ho ntša motlakase oa betri ho netefatsa hore hona joale ho na le sebaka se sireletsehileng; sensor ea voltage e sebelisoa ho beha leihlo matla a betri pakete ho netefatsa hore ha e lefelloe kapa ha e feteletsoe. Chip ea taolo e na le boikarabello ba ho bokella data ea sensor le ho laola le ho laola betri ka li-algorithms.

Ntle le moo, molemong oa ho ntlafatsa ts'ebetso ea polokelo ea matla ea libeteri tsa lithium-ion, taolo e nepahetseng ea tefiso ea betri le ho tsoa le eona ea hlokahala. Mohlala, ho tjhaja kamehla le ho tjhaja motlakase o sa feleng ho ka sebelisoa nakong ea ho tjhaja, 'me motlakase le motlakase li ka fetoloa ho latela litlhoko nakong ea ho tjhaja. Ka ho laola tefiso le ts'ebetso ea ho tsoa, ​​matla a ho fetola matla a betri a ka holisoa 'me bophelo ba ts'ebeletso ea betri bo ka eketsoa.

Ka kakaretso, polokelo ea matla ea likoloi tse tsamaeang ka matla e fumaneha ka libeteri tsa lithium-ion. Libetri tsena li boloka matla a motlakase le ho a lokolla ha ho hlokahala. Ka ts'ehetso ea sistimi ea taolo ea betri, polokeho le ts'ebetso ea betri li ka netefatsoa. Ka nako e ts'oanang, ka ho ntlafatsa tjhaja le taolo ea ho tsoa, ​​ts'ebetso ea polokelo ea matla e ka ntlafatsoa mme bophelo ba betri bo ka eketsoa. Ntlafatso e tsoelang pele le boqapi ba theknoloji ea polokelo ea matla e tla khothaletsa nts'etsopele le ts'ebeliso ea mehala
