Baytariyada lithiumku miyay u baahan yihiin nidaamka maaraynta (BMS)?

Dhowr baytari oo lithium ah ayaa si taxane ah loogu xidhi karaa si ay u sameeyaan baakidh batari ah, kaas oo awood siin kara culaysyo kala duwan sidoo kale waxa si caadi ah loogu dalaci karaa dallad isbarbar socda. Beteriyada lithium uma baahna wax nidaam maaraynta baytari ah (BMS) in la dallaco oo laga saaro. Haddaba maxay tahay sababta dhammaan baytariyada lithium-ka ee suuqa ku jira ay ugu daraan BMS? Jawaabtu waa badbaado iyo cimri dherer.

Nidaamka maaraynta baytariyada BMS (Nidaamka Maaraynta baytariga) waxa loo isticmaalaa si loola socdo oo loo xakameeyo dallacaadda iyo dallacaadda baytariyada dib loo dallaci karo. Hawsha ugu muhiimsan ee nidaamka maaraynta baytariyada lithium (BMS) waa in la hubiyo in baytariyadu ku sii jiraan xadka hawlgalka ee badbaadada leh iyo in la qaado tillaabo degdeg ah haddii batari kastaa bilaabo inuu dhaafo xadka. Hadii uu BMS-ku ogaado in danabku uu aad u hooseeyo, waxa uu jarayaa culayska, haddii uu korantadu aad u sarreeyo, waxa uu jarayaa dabaysha. Waxa kale oo ay hubin doontaa in unug kasta oo baakidhku ku jiro uu isku dan yahay oo uu yareeyo danab kasta oo ka sarreeya unugyada kale. Tani waxay hubinaysaa in batarigu aanu gaadhin koronto yar oo khatar ah-taas oo inta badan sabab u ah batteriga lithium ee aan ku aragno wararka. Waxay xitaa la socon kartaa heerkulka batteriga oo waxay ka gooyn kartaa batteriga ka hor inta uusan aad u kululaanin inuu dab qabsado. Sidaa darteed, nidaamka maaraynta batteriga BMS waxa uu ogolaadaa in batteriga la ilaaliyo halkii ay kaliya ku tiirsanaan lahaayeen dajiyaha wanaagsan ama hawlgalka isticmaale ee saxda ah.

Waa maxay sababta'Ma baytariyada lead-acid waxay u baahan yihiin nidaamka maaraynta baytariyada? Halabuurka baytariyada sunta rasaasta waa mid aan guban karin, taas oo ka dhigaysa in ay aad u yar tahay in uu dab qabsado haddii ay jirto dhibaato ku saabsan dallacaadda ama soo daynta. Laakiin sababta ugu weyni waxay la xiriirtaa sida batteriga u dhaqmo marka uu si buuxda u dallaco. baytariyada lead-ashitada sidoo kale waxay ka samaysan yihiin unugyo si taxane ah ugu xidhan; Haddii hal unug uu wax yar ka dallaco unugyada kale, waxa ay u dayn doontaa oo kaliya in ay imminka dhaafto ilaa unugyada kale ay si buuxda u dallacaan, iyada oo la ilaalinayo danab macquul ah, iwm. Unugyadu way qabsanayaan. Sidan, baytariyada acid-ashitada "isku dheelitiraan" markay dallacaan.

Baytariyada lithium way kala duwan yihiin. Electrode-ka togan ee baytariyada lithium-ka ee dib loo dallaci karo ayaa u badan maaddada lithium ion. Mabda'a shaqada ayaa go'aaminaya in inta lagu jiro habka dallacaadda iyo bixinta, lithium electrons waxay u socon doonaan labada dhinac ee korantada togan iyo kuwa taban mar kale iyo mar kale. Haddii danabka hal unug loo oggolaado inuu ka sarreeyo 4.25v (marka laga reebo baytariyada lithium-ka-sare), qaab-dhismeedka microporous anode ayaa laga yaabaa inuu burburo, walxaha crystal-ka adag ayaa laga yaabaa inay koraan oo ay keenaan wareeg gaaban, ka dibna heerkulku wuu kici doonaa. si degdeg ah, oo aakhirka keenta dab. Marka batteriga lithium-ka si buuxda loo dallaco, danabku si lama filaan ah ayuu u kacaa oo si degdeg ah ayuu u gaadhi karaa heerar khatar ah. Haddii danabka unug gaar ah oo ku jira baakidhku uu ka sarreeyo unugyada kale, unuggani wuxuu marka hore gaari doonaa danabka khatarta ah inta lagu jiro habka dallacaadda. Waqtigan xaadirka ah, korantada guud ee xirmada batteriga weli ma gaarin qiimaha buuxa, dabeyshu ma joojin doonto dallacaadda. . Sidaa darteed, unugyada marka hore gaadha danabyada khatarta ah waxay keeni doonaan khataro badbaado. Sidaa darteed, xakamaynta iyo la socodka wadarta tamarta xidhmada batteriga kuma filna kiimikooyinka ku salaysan lithium. BMS waa inay hubisaa tamarta unug kasta oo gaar ah oo ka kooban xirmada batteriga.

Sidaa darteed, si loo hubiyo badbaadada iyo nolosha adeegga dheer ee xirmooyinka baytariga lithium, nidaam maarayn batari tayo leh oo lagu kalsoonaan karo ayaa runtii loo baahan yahay BMS.
