Amabhethri e-Lithium-ionziye zaba yonke indawo ekuphileni kwansuku zonke.Bakhona yonke indawo, kusukela kuma-smartphones kuya kumalaptop, izimoto zikagesi kuya kumabhange asebenza ngogesi.Lawa mabhethri ayasebenza, ahlangene, futhi angagcina amandla.Nokho, lawa mandla kuza umthwalo.Ukuphatha okufanele kanye nezinyathelo zokuphepha kuyadingeka uma kuziwa kumabhethri e-lithium-ion.
Ingxenye eyodwa ebalulekile yokuphepha nokusebenza kwamabhethri e-lithium-ion i-Battery Management System (BMS).I-BMS iqapha futhi ilawule ukushajwa kwebhethri, ukuchithwa, izinga lokushisa, namandla kagesi futhi ivikela ibhethri ekushajweni ngokweqile, ekuchithekeni ngokweqile, namasekhethi amafushane.Kulesi sihloko, sizogxila endleleni yokusebenzisa 4s Li-ion lithium 18650 ibhethri BMS amaphakethe PCB ukuvikela ibhodi.
Iyini i-4s Li-ion lithium 18650 yebhethri ye-BMS yamaphakethe webhodi lokuvikela le-PCB?
Ibhethri ye-4s Li-ion lithium 18650 BMS iphakethe ibhodi lokuvikela le-PCB ibhodi lesekethe elincane elakhelwe ukuvikela ibhethri ezingozini ezihlukahlukene njengokushajwa ngokweqile, ukushajwa ngokweqile, amasekhethi amafushane, nokushintshashintsha kwezinga lokushisa.Ibhodi liqukethe iyunithi yesilawuli esincane (i-MCU), amaswishi e-MOSFET, ama-resistors, ama-capacitor, nezinye izakhi ezisebenza ndawonye ukuze ziqaphe amandla kagesi ebhethri namazinga amanje kanye nokulawula ukushajwa nokushajwa kwebhethri.
I-"4s" egameni le-BMS ibhekisela enanini lamaseli ephaketheni lebhethri.I-18650 ibhekisela kusayizi wamaseli e-lithium-ion.Iseli ye-18650 iyiseli ye-lithium-ion eyicylindrical ekala u-18mm ububanzi no-65mm ubude.
Kungani usebenzise i-4s Li-ion lithium 18650 yebhethri ye-BMS iphakethe ibhodi lokuvikela le-PCB?
Ukusebenzisa i-4s Li-ion lithium 18650 ibhethri ye-BMS pack PCB ibhodi yokuvikela kubalulekile ngoba iqinisekisa ukusetshenziswa okuphephile nokusebenzayo kwebhethri.I-BMS yakhelwe ukuvimbela ibhethri ukuthi lingashaji kakhulu, lingashajwa kakhulu, futhi lishise ngokweqile.Ukushajwa ngokweqile kanye nokukhipha ngokweqile kungaholela emonakalweni ongalungiseki ebhethrini, kunciphise ukuphila kwayo, futhi kubangele nomlilo noma ukuqhuma.
Ngaphezu kwalokho, i-BMS inesibopho sokulinganisa amaseli kuphakethe lebhethri.Amaseli e-lithium-ion anobubanzi be-voltage obunomkhawulo, futhi uma iseli elilodwa lishajwe ngokweqile noma lishajwa kancane, lingaphazamisa ukusebenza kanye nokuphepha kwephakethe lebhethri.I-BMS iqinisekisa ukuthi wonke amaseli ephaketheni lebhethri ashajwa futhi ashajwa ngokulinganayo, okunweba ubude bempilo yebhethri.
Isetshenziswa kanjani i-4s Li-ion lithium 18650 ibhethri ye-BMS iphakethe ibhodi lokuvikela le-PCB?
Ukusebenzisa i-4s Li-ion lithium 18650 yebhethri ye-BMS amaphakethe webhodi lokuvikela le-PCB kulula futhi akudingi amakhono akhethekile noma amathuluzi.Nokho, kubalulekile ukulandela imiyalelo yomkhiqizi ngokucophelela ukuze uqinisekise ukusetshenziswa okuphephile nokusebenzayo kwebhethri.
Nazi izinyathelo zokusebenzisa i-4s Li-ion lithium 18650 yebhethri ye-BMS yamaphakethe webhodi lokuvikela le-PCB:
Isinyathelo 1: Qoqa izingxenye
Ngaphambi kokuba uqale ukuhlanganisa iphakethe lebhethri, kufanele uqoqe zonke izingxenye ozidingayo.Lokhu kuhlanganisa amaseli angu-18650, ibhodi le-BMS, isibambi sebhethri, izintambo, nensimbi yokunamathisela.
Isinyathelo sesi-2: Lungiselela amaseli
Hlola iseli ngalinye ukuze wenze isiqiniseko sokuthi awonakele noma awaboshiwe.Bese, hlola i-voltage yeseli ngalinye usebenzisa i-multimeter.Amaseli kufanele abe namazinga kagesi afanayo.Uma noma yimaphi amaseli anezinga likagesi elihluke kakhulu, kungaba uphawu lokuthi iseli lonakele noma lisetshenziswe ngokweqile.Faka esikhundleni noma yimaphi amaseli alimele noma anephutha.
Isinyathelo sesi-3: Hlanganisa iphakethe lebhethri
Faka amaseli kusibambi sebhethri, uqinisekise ukuthi i-polarity ilungile.Bese, xhuma amaseli ochungechungeni.
