Ungayikhetha njani eyona Bhodi yoKhuselo ye-LITIAM ibhegi

Izinto eziphambili zokuThatha:

Ibhodi yokhuseleko kunye ne-BMS ukubaluleka: Kubalulekile ukhuseleko lwebhetrium, ukuthintela ukugqithisa, ukukhulula ngaphezulu, kunye nokubaleka kwe-thermal.
Izinto eziphambili: Iibhodi zoKhuselo ziquka i-ICS yokubeka esweni kunye nolawulo, iiMosfETs zolawulo lwangoku, kunye nezinto ezongezelelweyo ezifana namandla kunye nabaqengqelekayo ukuze bazinze.
I-BMS VS. Ibhodi yokhuseleko: I-BMS ibonelela ngezinto eziphambili kubandakanya ukulinganisa i-galting kunye nonxibelelwano, lifanelekile kwi-voltage ephezulu kunye neepakethi ezinkulu zebhetri.
Izinto zokukhetha: Cinga ngesantya sepakethe, i-voltage, ikhemistri, inqanaba le-AH, isicelo, kunye nendawo yokusebenza xa ukhetha iBhodi yokuKhuselwa.
Iibhodi eziKhuselweyo eziKhuselweyo: Nika izisombululo ezinemigaqo ehambelana nebhetri kunye neemfuno zesixhobo sentsebenzo eyoneleyo kunye nokhuseleko.
Izitishi zezokhuseleko: Ibalulekile ekuqinisekiseni imveliso yokhuseleko, ukuthengisa, ukuthotyelwa komthetho, kunye nokuzithemba kwabathengi, ngeMigangatho ye-DOT 38.3, i-IEC 3213, i-IEC 2084, kwaye kumakishwa.

Ngenxa yoxinano lwamandla aphezulu, iibhetri ze-lithium Ube ngumthombo wamandla ofanelekileyo kwizixhobo ezahlukeneyo ze-elektroniki kunye nokusetyenziswa. Nangona kunjalo, iimpawu zekhemikhali zeLithium Biteries zikwabangela ingozi ethile yokhuseleko. Imicimbi enjengokukhupha ngaphezulu, ukukhululeka ngaphezulu, kunye nokukhutshwa okuphezulu kungakhokelela ekumonakaleni ibhetri, i-lounedpan, kunye neengozi zokhuseleko.

Ukukhusela ngokuchasene nolo lwazi, iibhodi zokhuselo ze-Lithium zabakho. Ezi bhodi zinikiwe ukubonelela ngemisebenzi yokubeka esweni kunye nokukhusela kwiibhetri ze-lithium ze-lithium. Iibhetri zevotium ye-lithium ephezulu ye-lithium, i-testries ebanzi Inkqubo yoLawulo lwebhetri (ii-BMS) isetyenziswa ngokuqhelekileyo, ebonelela ngeliso le-nuesuped nangaphezulu kwepakethi yebhetri.

Amalungu aphambili & Imisebenzi yeBhodi yokuKhusela

Nangona incinci ngokobukhulu, ulwakhiwo lwangaphakathi nemisebenzi yeBhodi yokhuseleko inobunzima kakhulu kwaye inzima. Ibunjwe ikakhulu kwezi zinto ziphambili zilandelayo, nganye idlala indima engenakuphikwa ekukhuseleni ukhuseleko ibhetri.

Indima yeSekethe ezihlanganisiweyo (i-ICs)

Iisekethe ezihlanganisiweyo (i-IC) zisebenza njengengqondo yeBhodi yokuKhuselwa, enoxanduva lokulungisa nokulawula yonke imisebenzi yokhuselo lwebhetri. Babeka iliso kwi-voltage yebhetri, okwangoku, kunye neeparamitha zeqondo lobushushu ngexesha lokwenyani ngenkqubo eyakhiwe kunye nee-algorithms.

Xa ezi paramitha zigqitha kwimilinganiselo yokhuseleko ethethwayo, ii-IC ngokukhawuleza imiyalelo yokuhlengahlengisa okanye inqumle ibhetri yebhetri ukunqanda umonakalo onokubakho.

Ukusebenza nokuchaneka kwee-IC kunxulumene ngokuthe ngqo nokusebenza ngokupheleleyo nokuxhomekeka kwinkqubo yokhuselo.

Ukubaluleka kokutshintsha izinto (ezinjenge mosfets)

I-Mosfets (i-7 yentsimbi-oxide-i-semicondcuctors intsimi-ibala) ziziseko zokutshintsha kwiBhodi yokuKhusela. Ilawula ukutshaja kunye nokukhupha iindlela zebhetri ngokwemiyalelo ye-Ic.

Xa ikhutshiwe, ukukhululeka ngaphezulu, okanye ezinye iimeko ezingaqhelekanga zifunyenwe, iiMosfets zinokusika ngokukhawuleza ukukhusela umonakalo kwibhetri.

Ukuphendula okukhawulezayo kweMosfets yeyona nto ibaluleke kakhulu ekukhuseleni ibhetri kwiimeko ezingalindelekanga.

Imisebenzi yenye into ephambili (amachaphaza, abaqeqeshayo, njl. Njl.)

Ngaphandle kwe-iCSFETS, iibhodi zokhuselo zixhotyiswe uluhlu lwezixhobo ze-elektroniki ezongezelelweyo, ezifana namandla kunye nabaphathi.

Amandla anikwe umsebenzi wokuzinzisa amandla, ukunciphisa ukuguquguquka kwe-voltage, kunye nokukhusela ibhetri ukusuka kwi-volti ephezulu okanye i-voltage ye-voltage.

Abaphengululi baqeshwe ukulawula okwangoku, ukuqinisekisa ukuba ibhetri isebenza ngaphakathi koluhlu olukhuselekileyo lwangoku.

Umahluko phakathi kweBHM kunye neBhodi yoKhuselo

Nangona i-BMS kunye neBhodi yokuKhusela zombini zinxulumene nokhuseleko lwebhetri kunye nolawulo lwentsebenzo, bahluke kakhulu ekusebenzeni nasebunzima.

Inkcazo kunye nezinto eziphambili ze-BMS

I-BMS yinkqubo entsonkothileyo ye-elektroniki. Ayiqukanga imisebenzi esisiseko yeBhodi yokuKhusela, njengokugqitha ngaphezulu, ukukhululeka ngaphezulu, ukukhululeka, kunye nokukhuselwa kwesekethe, kodwa kukhulisa imisebenzi ephambili.

I-BMS ingajonga imeko yebhetri ngexesha lokwenyani, kubandakanya i-voltage, ekhoyo, ubushushu, kunye nenqanaba lokuhlawula, kunye nemeko yeseli nganye.
Iququzelela Ukulungelelaniswa kwebhetri.
I-BMS ixhotywe ngonxibelelwano lonxibelelwano oluvumela ukutshintshiselana ngedatha ngezixhobo zangaphandle (ezinje ngee-chargers, iinkqubo zokubeka iliso, okanye ezinye izixhobo ze-elektroniki), zivumela ulawulo lwebhetri.

Izinto ekufuneka ziqwalaselwe xa ukhetha ibhodi yokhuselo

Xa ulingelela iBhodi yeLithium ye-Lithium efanelekileyo, kukho izinto ezininzi eziphambili ekufuneka uziqwalasele ukuqinisekisa ukhuseleko lwebhetri kunye nokusebenza kakuhle. Nazi iindawo ezintathu ekufuneka uzinikele ingqalelo ngexesha lenkqubo yokhetho:

Ubungakanani bepakethi yebhetri kunye ne-voltage

Ubungakanani kwaye I-voltage yepakethi yebhetri ziiparamitha ezisisiseko zokukhetha iBhodi yokuKhusela.

Iipakethi ezahlukeneyo zebhetri zinokuba nobungakanani bokwahluka kunye neemfuno zevolthi, kwaye iBhodi yokuKhuselwa kufuneka ihambelane nezi mpawu.

Umzekelo, ipakethi encinci yebhetri inokufuna iBhodi yoKhuselo eDica, ngelixa ipakeji ye-voltage ephezulu yayinokufuna iBhola yokhuseleko enokufumana iBhodi yokhuseleko enokufumana i-voltages ephezulu.

Ubume bemichiza yebhetri kunye ne-ah (iyure ye-AMPE)

Ibhetri yebherey kunye neiyure ze-Amprere-iyure echaza amandla ayo amandla kunye neempawu zokuphelisa. Iipropathi zeekhemikhali ezahlukeneyo zinokufuna iindlela ezahlukeneyo zokukhusela kunye netekhnoloji.

Umzekelo, iibhetri ezineempawu ezithile zeekhemikhali zinokuba nengqondo ngakumbi kuguquko lobushushu, ngelixa abanye befuna ulawulo olululo lokubiza. Iibhetri ezinamanqanaba aphezulu e-AH aya kukhutshwa ngakumbi okwangoku ngexesha lokukhupha, oko oko kunyanzelisa iBhodi yokuKhuselo enokuthintela amanqanaba aphezulu.

Ukusetyenziswa kwenjongo kunye nendawo yokusebenza yepakethi yebhetri

Imeko yesicelo kunye nendawo yokusebenza yepakethi yebhetri inefuthe elibonakalayo kwintsebenzo yalo kunye neemfuno zoKhuselo.

Umzekelo, ukuba ipakeji yebhetri imiselwe izixhobo zangaphandle, iBhodi yokuKhuselo kufuneka ikwazi ukukhona kwiimeko zemozulu eziqatha, ezinje ngamaqondo obushushu aphezulu, amaqondo obushushu asezantsi, kunye nokufuma.

Ngokufanayo, ukuba ibhetri yebhetri iya kuthunyelwa kwiindawo ezinentshukumo ephezulu okanye ifuthe eliphezulu, iBhodi yokuKhusela kufuneka ibonise ukomelela kunye nokomelela ukuze abo banyamezele abo bangaphandle.
