Kutheni iibhetri ze-lithium zifuna i-BMS?

Iibhetri zeLithiumziya zithandwa kakhulu kwizixhobo zombane ezahlukeneyo ngenxa yobuninzi bazo kunye nobomi obude.Nangona kunjalo, enye yezinto eziphambili eziyimfuneko ukukhusela iibhetri ze-lithium kwaye zibenze basebenze ngokufanelekileyoinkqubo yolawulo lwebhetri (BMS).Umsebenzi oyintloko we-BMS kukukhusela iiseli zeebhetri ze-lithium, ukugcina ukhuseleko kunye nokuzinza ngexesha lokutshaja ibhetri kunye nokukhupha, kwaye udlale indima ebalulekileyo ekusebenzeni kwayo yonke inkqubo yesekethe yebhetri.

Ke, kutheni iibhetri ze-lithium zifuna i-BMS?Impendulo ilele kuhlobo lweebhetri ze-lithium ngokwazo.Iibhetri zeLithium zaziwa ngoxinaniso lwazo lwamandla aphezulu kunye nomthamo wombane ophezulu ngokwentelekiso, nto leyo ezenza zibe sesichengeni sokufudumeza, ukutshaja kakhulu, ukudischarging, kunye nokujikeleza okufutshane.Ngaphandle kokhuseleko olululo kunye nolawulo olululo, le miba inokukhokelela kwiingozi zokhuseleko ezifana nokubaleka kwe-thermal, umlilo, kunye nokuqhuma.

Kulapho BMSuyadlala.I-BMS ibeka iliso kwisimo seseli nganye ngaphakathi kwebhetri ye-lithium kwaye iqinisekisa ukuba bayahlawula kwaye bakhuphe ngaphakathi kwendawo ekhuselekileyo.Ikwabonelela ngokhuseleko ekugqithiseni kunye nokukhutshwa ngokugqithisileyo ngokulinganisa umbane weseli nganye kunye nokunqunyulwa kwamandla xa kuyimfuneko.Ukongeza, i-BMS inokubona kwaye ithintele izizathu eziqhelekileyo zokungaphumeleli kwebhetri ye-lithium ezifana neesekethe ezimfutshane, i-overcurrent, kunye ne-overtemperature.

Ukwengeza,BMSinceda ukwandisa ubomi beebhetri ze-lithium ngokuthintela imiba efana nokungalingani kweeseli, ezinokubangela ukungahambi kakuhle kwamandla kunye nokunciphisa ukusebenza kwebhetri jikelele.Ngokugcina ibhetri phakathi kolona luhlu lusebenza kakhulu, i-BMS iqinisekisa ukuba ibhetri isebenza ngokufanelekileyo nangokukhuselekileyo kubo bonke ubomi bayo.

Ukushwankathela, i-BMS licandelo eliphambili ekusebenzeni okukhuselekileyo nokuthembekileyo kweebhetri ze-lithium.Kubalulekile ukukhusela iiseli zebhetri, ukugcina ukhuseleko kunye nokuzinza ngexesha lokutshaja kunye nokukhupha, kunye nokuphucula ukusebenza ngokubanzi kwenkqubo yebhetri.Ngaphandle kwe-BMS, ukusebenzisa iibhetri ze-lithium kubeka imingcipheko ebalulekileyo yokhuseleko kwaye kunokukhokelela ekungaphumelelini kwangaphambi kwexesha.Ngoko ke, kuzo zonke izicelo zebhetri ye-lithium, ukufakwa kwe-BMS kubaluleke kakhulu ekusebenzeni kwayo okufanelekileyo kunye nokuphila ixesha elide.
