Intshayelelo:
Ngamazwi alula, ukulinganisela yi-voltage ephakathi yokulinganisela. Gcina i-voltage yeibhetri ye-lithiumukuhambelana. Ukulinganisela kwahlulwe ngokulinganisela okusebenzayo kunye nokulinganisela okungasebenziyo. Ngoko ke yintoni umahluko phakathi kokulinganisela okusebenzayo kunye nokulinganisela okungasebenziyo kwebhodi yokukhusela ibhetri ye-lithium? Makhe sijonge ngeHeltec Energy.
Ukulinganisela okusebenzayo kwebhodi yokukhusela ibhetri ye-lithium
Ukulinganisela okusebenzayo kukuba umtya one-voltage ephezulu wongeza amandla kumtya one-voltage ephantsi, ukuze amandla angachithwa, i-voltage ephezulu incitshiswe, kwaye i-voltage ephantsi incediswe. Olu hlobo lomtya olinganiselayo osebenzayo ungazikhethela ubungakanani bomtya olinganiselayo. Ngokusisiseko, i-2A isetyenziswa rhoqo, kwaye kukwakho nezinkulu ezine-10A okanye ngaphezulu.
Ngoku izixhobo zokulinganisela ezisebenzayo ezikwimarike zisebenzisa umgaqo we-transformer, zixhomekeke kwiitships ezibizayo zabavelisi beetships. Ukongeza kwi-chip yokulinganisela, kukwakho nezinto ezibizayo ezifana nee-transformers, ezinkulu ngobukhulu kwaye zibiza kakhulu.
Isiphumo sokulinganisela okusebenzayo sicacile kakhulu: ukusebenza kakuhle okuphezulu, amandla amancinci ayaguqulwa kwaye awachithwa ngendlela yobushushu, kwaye ilahleko kuphela yi-coil ye-transformer.
Umsinga wokulinganisela unokukhethwa kwaye isantya sokulinganisela siyakhawuleza. Ukulinganisela okusebenzayo kuyinkimbinkimbi ngakumbi kwisakhiwo kune-passive balancing, ingakumbi indlela ye-transformer. Ixabiso le-BMS elinomsebenzi wokulinganisela okusebenzayo liya kuba phezulu kakhulu kunelo lokulinganisela okusebenzayo, okukwathintela kancinci ukukhuthazwa kokulinganisela okusebenzayo.I-BMS.
Ukulinganisela okungasebenziyo kwebhodi yokukhusela ibhetri ye-lithium
Ukulinganisela okungasebenziyo kwenziwa ngokufaka ii-resistor kwi-discharge. Intambo yeeseli ezine-voltage ephezulu ikhutshwa ngendlela yokuchithwa kobushushu kwindawo ejikelezileyo, nto leyo efezekisa isiphumo sokupholisa i-resistor. Ingxaki kukuba i-discharge isekelwe kwintambo ye-voltage ephantsi, kwaye kukho ithuba lomngcipheko xa itshaja.
Ukulinganisela okungasebenziyo kusetyenziswa kakhulu ngenxa yexabiso layo eliphantsi kunye nomgaqo wayo olula wokusebenza; ingxaki yayo kukuba ilungelelaniswe ngokusekelwe kumandla aphantsi, kwaye ayinako ukongeza umtya we-voltage ephantsi, nto leyo ebangela inkunkuma yamandla.
Umahluko phakathi kokulinganisela okusebenzayo kunye nokulinganisela okungasebenziyo
Ukulinganisela okungasebenziyo kufanelekile kwii-voltage ezincinci, ezinomthamo omncinciiibhetri ze-lithium, ngelixa i-active balancing ifanelekile kwizicelo zebhetri ye-lithium enamandla aphezulu, enamandla amakhulu.
Iiteknoloji zokutshaja ezisetyenziswa rhoqo ziquka ukutshaja okulinganiselayo kwe-shunt resistor, ukutshaja okulinganiselayo kwe-shunt resistor on-off, ukutshaja okuphakathi kwe-voltage yebhetri, ukutshaja okulinganiselayo kwe-switch capacitor, ukutshaja okulinganiselayo kwe-buck converter, ukutshaja okulinganiselayo kwe-inductor, njl. Xa utshaja iqela leebhetri ze-lithium ezilandelelanayo, ibhetri nganye kufuneka itshajwe ngokulinganayo, kungenjalo ukusebenza kunye nobomi beqela lonke lebhetri kuya kuphazamiseka ngexesha lokusetyenziswa.

Umgaqo osisiseko wokulinganisela okungapheliyo kukufezekisa isiphumo sokulinganisela ngokuchitha amandla agqithisileyo. Ngokwesiqhelo, amandla agqithisileyo kwipakethi yebhetri egqithisileyo aguqulwa abe bubushushu nge-resistor, ukuze i-voltage yebhetri ihlale ihambelana. Inzuzo kukuba isekethe yokulinganisela engasebenziyo ilula kwaye iindleko zoyilo kunye nokuphunyezwa ziphantsi. Kwaye itekhnoloji yokulinganisela engasebenziyo ivuthiwe kakhulu kwaye isetyenziswa kakhulu kwiindleko ezininzi eziphantsi nezincinci.iipakethi zebhetri.
Ingxaki kukuba kukho ilahleko enkulu yamandla ngenxa yokuguqulwa kwamandla ombane abe bubushushu ngenxa yokumelana. Ukusebenza okuphantsi, ingakumbi kwiipakethe zebhetri ezinomthamo omkhulu, inkunkuma yamandla iyabonakala ngakumbi, kwaye ayifanelekanga kwizicelo zebhetri ezinkulu nezisebenza kakuhle. Kwaye ngenxa yokuba amandla ombane aguqulwa abe bubushushu, anokubangela ukuba ipakethe yebhetri ishushu kakhulu, nto leyo echaphazela ukhuseleko kunye nobomi benkqubo iyonke.
Ukulinganisela okusebenzayo kufezekisa ukulinganisela ngokudlulisela amandla ombane agqithisileyo ukusuka kwiibhetri ezine-voltage ephezulu ukuya kwiibhetri ezine-voltage ephantsi. Le ndlela ngokubanzi ilungisa ukusasazwa kwamandla phakathi kweebhetri ngokutshintsha izixhobo zombane, ii-buck-boost converters okanye ezinye izinto ze-elektroniki. Inzuzo kukusebenza kakuhle okuphezulu: amandla awachithwa, kodwa alungelelaniswa ngokudluliselwa, ngoko ke akukho lahleko yobushushu, kwaye ukusebenza kakuhle kudla ngokuba phezulu (ukuya kuthi ga kwi-95% nangaphezulu).
Ukonga amandla: Ekubeni kungekho nkunkuma yamandla, ifanelekile kwiinjini ezinkulu nezisebenza kakuhleibhetri ye-lithiumiinkqubo kwaye inokwandisa ubomi benkonzo yephakheji yebhetri. Isebenza kwiiphakheji zebhetri ezinkulu: Ukulinganisela okusebenzayo kulungele ngakumbi iiphakheji zebhetri ezinomthamo omkhulu, ingakumbi kwiimeko ezifana nezithuthi zombane kunye neenkqubo zokugcina amandla, kwaye kunokuphucula kakhulu ukusebenza kakuhle kwenkqubo kunye nokunyamezela.
Ingxaki kukuba uyilo kunye nokusetyenziswa kokulinganisela okusebenzayo kuyinkimbinkimbi, kudla ngokufuna izinto ze-elektroniki ezingaphezulu, ngoko ke iindleko ziphezulu. Ubunzima bobuchwephesha: Ulawulo oluchanekileyo kunye noyilo lwesekethe ziyafuneka, nto leyo enzima kwaye inokunyusa ubunzima bophuhliso kunye nokugcinwa.
