Iibhetri ze-lithium ze-polymer, ezikwabizwa ngokuba ziibhetri ze-lithium polymer okanye iibhetri ze-LiPo, zifumana ukuthandwa kumashishini ahlukeneyo ngenxa yoxinano lwamandla aphezulu, uyilo olukhaphukhaphu, kunye nokuphuculwa kweempawu zokhuseleko.Nangona kunjalo, njengayo nayiphi na enye ibhetri, iibhetri ze-lithium ze-polymer ngamanye amaxesha zinokujongana nemiba efana nokungalingani kwamandla ebhetri.Eli nqaku lijolise ekuxoxeni izizathu zokungalingani kwamandla ebhetri kwi-aipakethe yebhetri ye-lithium polymerkunye nokubonelela ngobuchule obusebenzayo bokujongana nayo.
Ukungalingani kwamandla ebhetri kwenzeka xa amanqanaba ombane ebhetri nganye ngaphakathi kwepakethi yebhetri ye-lithium yepolymer eguquguquka, ekhokelela kulwabiwo lwamandla olungalinganiyo.Oku kungalingani kunokukhokelela kwizinto ezininzi, kubandakanya umahluko okhoyo kumandla ebhetri, iziphumo zokwaluphala, ukwahluka kwemveliso, kunye neepatheni zokusetyenziswa.Ukuba ishiywe ingahoywanga, ukungalingani kwamandla ebhetri kunokunciphisa ukusebenza kwebhetri kukonke, kunciphise umthamo webhetri, kwaye kubeke esichengeni ukhuseleko.
Ukujongana nokungalingani kwamandla ebhetri ngokufanelekileyo, amanyathelo ahlukeneyo anokuphunyezwa.Okokuqala, kubalulekile ukukhetha umgangatho ophezuluipolymer lithium ibhetriiiseli ezivela kubavelisi abathembekileyo.Ezi seli kufuneka zibe neempawu zombane ezingaguqukiyo kwaye zingene kwiinkqubo ezingqongqo zolawulo lomgangatho ukunciphisa amathuba okungalingani kwamandla ombane okwenzekayo kwindawo yokuqala.
Okwesibini,Iinkqubo ezifanelekileyo zolawulo lwebhetri (BMS) zibalulekile ekubekeni iliso nasekulinganiseni amanqanaba ombane ngaphakathiipakethe yebhetri ye-lithium polymer.I-BMS iqinisekisa ukuba iseli nganye yebhetri iyatshajiswa kwaye ikhutshwe ngokulinganayo, ithintela nayiphi na imiba yokungalingani.I-BMS isoloko ilinganisa amandla ombane kwiseli nganye, ichonge nakuphi na ukungalingani, kwaye isebenzisa iindlela zokulinganisa ukulinganisa amanqanaba ombane.Ukulinganisa kunokufezekiswa ngeendlela ezisebenzayo okanye ezizenzekelayo.
Ulungelelwaniso olusebenzayo lubandakanya ukusasazwa ngokutsha kwentlawulo egqithisileyo ukusuka kwiiseli zevoltage ephezulu ukuya kwiiseli zevoltage ezisezantsi, ukuqinisekisa amanqanaba ombane afanayo.Le ndlela isebenza ngakumbi kodwa idinga ukujikeleza okongeziweyo, ukunyuka kweendleko kunye nobunzima.Ukulinganisa okungahambiyo, kwelinye icala, kuxhomekeke kwizixhobo zokuchasa ukukhupha intlawulo egqithisileyo kwiiseli eziphezulu zevoltage.Ngelixa kuncinci kwaye kungabizi kakhulu, ukulinganisa okungahambiyo kunokuchitha amandla agqithisileyo njengobushushu, okukhokelela kukungasebenzi kakuhle.
Ngaphezu koko,Ukugcinwa rhoqo kwebhetri yokugcinwa kwebhetri kubalulekile ukuthintela kunye nokujongana nokungalingani kwamandla ebhetri.Oku kubandakanya ukubeka esweni amandla ombane eipakethi ewonke kunye nombane weseli nganye rhoqo.Ukuba kufunyenwe ukungalingani kwamandla ombane, ukutshaja okanye ukukhupha iiseli ezichaphazelekayo ngokwahlukeneyo kunganceda ukulungisa umba.Ukongeza, ukuba iseli ihlala ibonisa umahluko omkhulu wombane xa kuthelekiswa nabanye, inokufuna ukutshintshwa.
Ngaphezu koko,iindlela ezifanelekileyo zokutshaja nokukhupha zibalulekile ekugcineni amandla ombane alungeleleneyo ngaphakathi aipakethe yebhetri ye-lithium polymer.Ukutshaja okanye ukukhupha ngaphezulu kweeseli zomntu ngamnye kunokubangela ukungalingani kwamandla ombane.Ke ngoko, kubalulekile ukusebenzisa iitshaja ezenzelwe ngokukodwa iibhetri ze-lithium ze-polymer ezibonelela ngombane kunye nommiselo wangoku.Ukongeza, ukunqanda ukukhutshwa okunzulu kunye nokulayisha kakhulu ipakethi yebhetri kuqinisekisa ukuba iivoltages zeeseli zihlala zilungelelene ngokuhamba kwexesha.
Ukuqukumbela, nangona ukungalingani kwamandla ebhetri kuyinkxalabo enokubakho kwiipakethi zebhetri ye-lithium yepolymer, ukhetho olufanelekileyo lweeseli zebhetri ezikumgangatho ophezulu, ukuphunyezwa kwenkqubo yokulawula ibhetri ethembekileyo, ukugcinwa rhoqo, kunye nokubambelela kwiindlela zokutshaja ezifanelekileyo kunokunciphisa ngokufanelekileyo lo mbandela.Iibhetri ze-lithium ze-polymer zibonelela ngeengenelo ezininzi, kwaye kunye nemigqaliselo efanelekileyo, zinokubonelela ngomthombo wamandla okhuselekileyo nosebenzayo kwizicelo ezahlukeneyo kwixesha elizayo.
