Isingeniso:
Ama-chips ahlobene namandla kuhlale kunesigaba semikhiqizo etholile ukunakwa okuningi. Ama-bearter vitrove chips uhlobo lwama-chip ahlobene namandla asetshenziselwa ukuthola izimo ezihlukene zephutha kumabhethri e-cell eyodwa nama-multi-cell. Kuzinhlelo zanamuhla zebhethri, izici zamabhethri e-lithium-ion alungele izinhlelo eziphathwayo ze-elekthronikhi, kodwaamabhethri e-lithiumUdinga ukusebenza ngaphakathi kwemikhawulo ekalwe, egxile ekusebenzeni nasekuphepheni. Ngakho-ke, ukuvikelwa kwamaphakethe webhethri e-lithium-ion kuyadingeka futhi kubucayi. Ukusetshenziswa kwemisebenzi ehlukahlukene yokuvikela ibhethri ukugwema ukwenzeka kwezimo zephutha njengokukhipha i-OCD ye-OCD kanye nokushisa ngokweqile, nokuthuthukisa ukuphepha kwamaphakethe webhethri.
Uhlelo Lokuphathwa Kwebhethri lwethula ubuchwepheshe bokulinganisa
Okokuqala, ake sixoxe ngenkinga evame kakhulu yamaphakethe ebhethri, ukuvumelana. Ngemuva kokuthi amaseli angashadile akha iphakethe lebhethri le-lithium, ama-traway ashisayo kanye nezimo ezahlukahlukene zephutha kungenzeka. Le yinkinga ebangelwa ukungahambisani kwe-Lithium Battery Pack. Amangqamuzana athile enza i-Lithium Battery Pack ayihambisani namandla, ukushaja, kanye nokukhipha amapharamitha, kanye ne- "barrel effect" ibangela amaseli angashadile anezakhiwo ezimbi kakhulu ze-Lithium Battery Pack.
I-Lithium Battery Balancing Technology ibonwa njengendlela engcono kakhulu yokuxazulula ukuvumelana kwamaphakethe webhethri le-lithium. Ukulinganisa ukuguqula amavolushi wesikhathi sangempela samabhethri amakhono ahlukene ngokulungisa ukulinganisa kwamanje. Amandla anamandla okulinganisa, amandla okucindezela ukucindezela ukwanda komehluko we-voltage futhi avikele ukugijima okushisayo, futhi kungcono ukuvumelana nezimo kuI-Lithium Battery Pack.
Lokhu kwehlukile kumvikeli osuselwa ku-Hardware olula. Umvikeli we-Lithium Battery angaba umvikeli oyisisekelo we-overvoltage noma umvikeli othuthukile ongaphendula ngokuvikelwa phansi, amaphutha okushisa noma iphutha lamanje. Ngokuvamile, i-IC Management IC ebhethri le-Lithium Battery Monitor kanye negeji kaphethiloli kunganikeza i-Lithium Battery Balancing umsebenzi. I-Lithium Battery Monitor inikeza umsebenzi wokulinganisa webhethri we-Lithium futhi ifaka nomsebenzi wokuvikela i-IC ngokucushwa okuphezulu. Igeji kaphethiloli inezinga eliphakeme lokuhlanganiswa, kufaka phakathi umsebenzi we-Lithium Battery Monitor, futhi ihlanganisa ama-algorithms athuthukile ngokuqapha kwayo.
Kodwa-ke, ezinye i-Lithium Vikert ICS manje futhi zifaka nemisebenzi yokulinganisa yebhethri ye-Lithium nge-FETS ehlanganisiwe, engakhipha amandla amabhethri aphezulu ngokuzenzakalela ngesikhathi sokushaja futhi agcine amabhethri aphansi ochungechungeni, ngaleyo ndlela alinganiseI-Lithium Battery Pack. Ngaphezu kokusebenzisa iqoqo eligcwele le-voltage, imisebenzi yamanje nezokuvikela lokuvikelwa lokushisa, i-battery protection ICS nayo iyaqala ukwethula imisebenzi yokulinganisa ukuze ihlangabezane nezidingo zokuvikelwa kwamabhethri amaningi.
Kusuka ekuvikelweni okuyisisekelo ekuvikelweni kwesibili
Kusuka ekuvikelweni okuyisisekelo ekuvikelweni kwesibili
Isivikelo esiyisisekelo kunazo zonke ukuvikela okuvela ngaphezulu. Yonke i-Lithium Battery Protection ICS ihlinzeka ngokuvikelwa ngokweqile ngokuya ngamazinga ahlukene okuvikela. Ngalesi sisekelo, abanye bahlinzeka ngokuvikelwa okuphezulu okuphezulu kanye nokukhipha okuphezulu, kanti abanye bahlinzeka nge-speccultage kanye nokukhishwa okuphezulu kakhulu kokuvikelwa ngokweqile. Kwamanye amaphakethe webhethri le-lithium aphezulu, lokhu kuvikelwa akusenele ukufeza izidingo ze-Lithium Battery Pack. Ngalesi sikhathi, i-Lithium Battery Protection IC enomsebenzi we-Lithium Battery ozimele wokulinganisa uyadingeka.
Lokhu kuvikelwa kungokwesivikelo sokuqala, esilawula izindleko nezinkokhelo zokukhipha ukuphendula ezinhlotsheni ezahlukahlukene zokuvikelwa kwamaphutha. Lokhu kulinganisa kungaxazulula inkinga yokubaleka okushisayo kweI-Lithium Battery Packngiyaphila. Ukuqothulwa kokushisa ngokweqile kwebhethri elilodwa le-lithium kuzodala ukulimala kwe-Lithium Battery Pack Balance switch switch kanye nakumelana. Ukulinganisa kwebhethri kwe-Lithium kuvumela ibhethri le-Lithium ngalinye elingenakuphika epaki le-Lithium Battery ukuze lilinganiselwe kumthamo ofanayo namanye amabhethri angenaphutha, ehlisa ubungozi bokubaleka okushisayo.
Njengamanje, kunezindlela ezimbili zokuthola ukulinganisa kwebhethri le-Lithium: Ukulinganisa okusebenzayo nokulinganisa nje. Ukulinganisa okusebenzayo ukudlulisa amandla noma ukushaja kusuka kumabhethri aphezulu we-voltage / ephezulu Ukulinganisa nje ukusebenzisa ama-resistors okusebenzisa amandla aphezulu noma amabhethri okushaja okuphezulu ukufeza inhloso yokunciphisa igebe phakathi kwamabhethri ahlukene. Ukulinganisa nje kunokulahleka kwamandla okuphezulu kanye nengozi eshisayo. Ngokuqhathanisa, ukulinganisa okusebenzayo kuyasebenza kakhulu, kepha i-algorithm yokulawula inzima kakhulu.
Ukusuka ekuvikelweni okuyisisekelo ekuvikelweni kwesibili, uhlelo lwebhethri lwe-lithium ludinga ukufezekiswa nge-lithium yebhethri lebhethri noma igeji yamafutha ukuze kufinyelelwe ukuvikelwa kwesibili. Yize ukuvikelwa okuyisisekelo kungasebenzisa i-Intelligent yebhethri ama-algorithms ahlakaniphile ngaphandle kokulawulwa kwe-MCU, izidingo zesibili zokuvikela ama-Lithium bebhethri namanje kwi-MCU yokwenza izinqumo ezingeni le-System. Iziqapha ze-Lithium zebhethri ama-lithium noma ama-gather ama-gaughs anemisebenzi yokulinganisa yebhethri.
Ukugcina
Ngaphandle kwabaqaphi bebhethri noma ama-galema ama-gauges anikezela ngemisebenzi yokulinganisa kwebhethri, ukuvikelwa kwe-ICS okunikezela ukuvikelwa okuyisisekelo akusekho okukhawulelwe ekuvikelweni okuyisisekelo okufana nokuvikelwa okuphezulu. Ngohlelo lokusebenza olukhulayo lweseli oluningiamabhethri e-lithium, amaphakethe ebhethri amakhulu azoba nezidingo eziphakeme neziphakeme zokuvikela ics, futhi ukwethulwa kwemisebenzi yokulinganisa kuyadingeka kakhulu.
Ukulinganisa kufana nohlobo lwesondlo. Ukushaywa ngakunye nokukhululwa kuzoba nenani elincane lokulimala kokulinganisa ukulinganisa umehluko phakathi kwamabhethri. Kodwa-ke, uma iseli lebhethri noma iphakethe lebhethri ngokwalo linezinkinga zekhwalithi, ukuvikelwa nokulinganisa azikwazi ukuthuthukisa ikhwalithi yephakethe lebhethri, futhi akuzona ukhiye wendawo yonke.
Uma unemibuzo noma ungathanda ukufunda okuningi, sicela ungangabazifinyelela kithi.
