Kungani amabhethri e-lithium edinga i-BMS?

Amabhethri e-lithiumziya ngokuya zithandwa emishinini ye-elekthronikhi ehlukahlukene ngenxa yokuminyana kwazo okuphezulu nokuphila isikhathi eside.Kodwa-ke, enye yezingxenye ezibalulekile ezidingekayo ukuze kuvikelwe amabhethri e-lithium futhi uwenze akwazi ukusebenza kahle yi-uhlelo lokuphatha ibhethri (BMS).Umsebenzi oyinhloko we-BMS ukuvikela amaseli amabhethri e-lithium, ukugcina ukuphepha nokuzinza ngesikhathi sokushaja nokukhipha ibhethri, futhi udlale indima ebalulekile ekusebenzeni kwalo lonke uhlelo lwesekethe yebhethri.

Ngakho-ke, kungani amabhethri e-lithium edinga i-BMS?Impendulo ilele kumvelo yamabhethri e-lithium ngokwawo.Amabhethri e-lithium aziwa ngokuminyana kwawo okuphezulu kwamandla kanye ne-voltage ephezulu uma kuqhathaniswa, okuwenza akwazi ukushisisa ngokweqile, ashajwe kakhulu, akhiphe ngokweqile, kanye nokujikeleza okufushane.Ngaphandle kokuvikelwa nokuphathwa okufanele, lezi zinkinga zingaholela ezingozini zokuphepha ezifana nokubaleka okushisayo, umlilo, ngisho nokuqhuma.

Lapha kulapho I-BMSkungene ukudlala.I-BMS iqapha isimo seseli ngayinye ngaphakathi kwephakethe lebhethri le-lithium futhi iqinisekisa ukuthi liyashaja futhi liyashajwa ngaphakathi kwebanga eliphephile.Iphinde inikeze isivikelo ekukhokhisweni ngokweqile nasekukhipheni ngokweqile ngokulinganisa ugesi weseli ngalinye kanye nokunqamula amandla lapho kudingeka.Ngaphezu kwalokho, i-BMS ingathola futhi ivimbele izimbangela ezivamile zokuhluleka kwebhethri ye-lithium njengamasekhethi amafushane, i-overcurrent, kanye nokushisa ngokweqile.

Ngaphezu kwalokho,I-BMSisiza ukunweba impilo yamabhethri e-lithium ngokuvimbela izinkinga ezinjengokungalingani kweseli, okungabangela ukungafani komthamo futhi kunciphise ukusebenza kwebhethri kukonke.Ngokugcina ibhethri ingaphakathi kwebanga elilungile lokusebenza, i-BMS iqinisekisa ukuthi ibhethri isebenza kahle nangokuphepha kukho konke ukuphila kwayo.

Ukufingqa, i-BMS iyingxenye ebalulekile yokusebenza okuphephile nokuthembekile kwamabhethri e-lithium.Ibalulekile ekuvikeleni amaseli ebhethri, ukugcina ukuphepha nokuzinza ngesikhathi sokushajwa nokushajwa, kanye nokwenza kahle konke ukusebenza kwesistimu yebhethri.Ngaphandle kwe-BMS, ukusebenzisa amabhethri e-lithium kubeka engcupheni enkulu yokuphepha futhi kungaholela ekuhlulekeni ngaphambi kwesikhathi.Ngakho-ke, kuzo zonke izinhlelo zokusebenza zebhethri ye-lithium, ukufakwa kwe-BMS kubalulekile ekusebenzeni kwayo okufanele nokuphila isikhathi eside.
