Amabhethri e-lithium e-polymer, aziwa nangokuthi amabhethri e-lithium polymer noma amabhethri e-LiPo, athola ukuduma ezimbonini ezihlukahlukene ngenxa yokuminyana kwawo okuphezulu kwamandla, ukwakheka okungasindi, nezici zokuphepha ezithuthukisiwe.Kodwa-ke, njenganoma yiliphi elinye ibhethri, amabhethri e-polymer lithium kwesinye isikhathi angabhekana nezinkinga ezinjengokungalingani kwamandla ebhethri.Lesi sihloko sihlose ukuxoxa ngezimbangela zokungalingani kwamandla kabhethri ku-aiphakethe lebhethri le-lithium polymerfuthi unikeze amasu asebenzayo okubhekana nakho.
Ukungalingani kwamandla kagesi webhethri kwenzeka lapho amazinga kagesi ebhethri ngalinye ngaphakathi kwephakethe lebhethri le-lithium polymer eshintshashintsha, okuholela ekusabalaliseni kwamandla okungalingani.Lokhu kungalingani kungabangelwa izici eziningi, okuhlanganisa umehluko wemvelo wamandla ebhethri, imiphumela yokuguga, ukuhluka kokukhiqiza, namaphethini okusetshenziswa.Uma kuyekwa kunganakiwe, ukungalingani kwamandla ebhethri kunganciphisa ukusebenza kwebhethri kukonke, kukhawulele umthamo wephakethe lebhethri, futhi kubeke engcupheni ukuphepha.
Ukubhekana nokungalingani kwamandla kagesi webhethri ngempumelelo, kungenziwa izinyathelo ezahlukahlukene.Okokuqala, kubalulekile ukukhetha izinga eliphezuluibhethri ye-polymer lithiumamaseli avela kubakhiqizi abahloniphekile.Lawa maseli kufanele abe nezici ze-voltage ezingaguquki futhi abhekane nezinqubo eziqinile zokulawula ikhwalithi ukuze kuncishiswe amathuba okungalingani kwamandla kagesi okwenzeka kwasekuqaleni.
Okwesibili,amasistimu okuphatha amabhethri afanele (BMS) abalulekile ekuqapheni nasekulinganiseni amazinga kagesi ngaphakathiiphakethe lebhethri le-lithium polymer.I-BMS iqinisekisa ukuthi iseli ngalinye lebhethri lishajwa futhi lishajwa ngokulinganayo, kuvimbele noma yiziphi izinkinga zokungalingani.I-BMS ilokhu ikala i-voltage yeseli ngalinye, ikhomba noma yikuphi ukungalingani, futhi isebenzisa amasu okulinganisa ukuze ilinganise amazinga kagesi.Ukulinganisa kungafinyelelwa ngokusebenzisa izindlela ezisebenzayo noma ezingenzi lutho.
Ukulinganisa okusebenzayo kuhilela ukusabalalisa kabusha ukushaja okweqile kusuka kumaseli aphezulu-voltage kuya kumaseli ane-voltage ephansi, ukuqinisekisa amazinga kagesi afanayo.Le ndlela iphumelela kakhulu kodwa idinga ukujikeleza okwengeziwe, izindleko ezikhulayo kanye nobunzima.Ukulinganisa okwenziwayo, ngakolunye uhlangothi, ngokujwayelekile kuncike ezintweni eziphikisayo ukuthi zikhiphe imali eningi kumaseli anamandla kagesi.Nakuba kuncane futhi kushibhile, ukulinganisa okwenziwayo kungakhipha amandla amaningi njengokushisa, okuholela ekungasebenzini kahle.
Ngaphezu kwalokho,ukugcinwa okujwayelekile kwephakethe lebhethri kubalulekile ukuze uvimbele futhi ubhekane nokungalingani kwamandla kagesi.Lokhu kufaka phakathi ukuqapha amandla ebhethri ephaketheni kanye nomthamo weseli ngalinye njalo.Uma kutholwa noma yikuphi ukungalingani kwamandla kagesi, ukushaja noma ukukhulula amaseli athintekile ngawodwana kungasiza ekulungiseni inkinga.Ukwengeza, uma iseli lihlala libonisa umehluko omkhulu wamandla kagesi uma liqhathaniswa namanye, lingadinga ukushintshwa.
Ngaphezu kwalokho,izinqubo ezifanele zokushaja nokukhipha amandla zibalulekile ekugcineni amandla kagesi alinganisiwe ngaphakathi aiphakethe lebhethri le-lithium polymer.Ukushaja ngokweqile noma ukudedela amaseli ngamanye kungabangela ukungalingani kwamandla kagesi.Ngakho-ke, kubalulekile ukusebenzisa amashaja aklanyelwe ngokukhethekile amabhethri e-lithium e-polymer ahlinzeka nge-voltage kanye nomthetho wamanje.Ukwengeza, ukugwema ukukhishwa okujulile nokulayisha ngokweqile iphakethe lebhethri kuqinisekisa ukuthi ama-voltage amaseli ahlala elinganisene ngokuhamba kwesikhathi.
Sengiphetha, nakuba ukungalingani kwamandla kagesi webhethri kuwukukhathazeka okungaba khona emaphaketheni ebhethri le-lithium polymer, ukukhetha okufanele kwamaseli ebhethri ekhwalithi ephezulu, ukuqaliswa kwesistimu yokuphatha ibhethri ethembekile, ukunakekelwa okuvamile, nokubambelela emikhubeni efanele yokushaja kunganciphisa ngempumelelo le nkinga.Amabhethri e-lithium e-polymer anikeza izinzuzo eziningi, futhi ngezinyathelo ezifanele, angahlinzeka ngomthombo wamandla ophephile nosebenza kahle wezinhlelo zokusebenza ezihlukahlukene esikhathini esizayo.
