Yintoni inkqubo yolawulo lwebhetri (BMS)?
Igama elipheleleyo leBMSyiNkqubo yoLawulo lwebhetri, inkqubo yolawulo lwebhetri.Sisixhobo esisebenzisana nokubeka iliso kwimeko yebhetri yokugcina amandla.Ikakhulu ilungiselelwe ulawulo olukrelekrele kunye nokugcinwa kweyunithi yebhetri nganye, ukuthintela ibhetri ekutshajweni nasekukhupheni kakhulu, ukwandisa ubomi benkonzo yebhetri, kunye nokubeka iliso kwimeko yebhetri.Ngokuqhelekileyo, i-BMS imelwe njengebhodi yesekethe okanye ibhokisi ye-hardware.
I-BMS yenye yeendlela ezisezantsi zenkqubo yokugcina amandla ebhetri.Inoxanduva lokujonga imeko yokusebenza yebhetri nganye kwiugcino lwamandla ebhetriiyunithi yokuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo kweyunithi yokugcina amandla.I-BMS inokubeka iliso kwaye iqokelele iiparamitha zikarhulumente zebhetri yokugcina amandla ngexesha lokwenyani (kubandakanywa kodwa kungaphelelanga apho kumbane webhetri enye, iqondo lobushushu lepali yebhetri, umjiko wesekethe yebhetri, umbane wesiphelo sebhetri. ipakethi yebhetri, ukuxhathisa ukugqunyelelwa kwenkqubo yebhetri, njl.njl.), kwaye yenze imfuneko Ngokohlalutyo kunye nokubalwa kwenkqubo, iiparamitha zokuvavanya urhulumente zifunyenwe, kunye nolawulo olusebenzayo lwenkqubo.ibhetri yokugcina amandlaumzimba uphunyezwa ngokwesicwangciso solawulo lokhuselo oluthile, ukuze kuqinisekiswe ukusebenza okukhuselekileyo nokuthembekileyo kwayo yonke iyunithi yokugcina amandla ebhetri.Ngelo xesha, i-BMS inokutshintshiselana ngolwazi kunye nezinye izixhobo zangaphandle (i-PCS, i-EMS, inkqubo yokukhusela umlilo, njl.) ngokusebenzisa i-interface yayo yonxibelelwano, igalelo le-analog / idijithali, kunye ne-interface yokufaka, kwaye yenze ulawulo lokudibanisa kwiinkqubo ezahlukeneyo ezingaphantsi kweendlela. Isikhululo samandla esipheleleyo sogcino lwamandla ukuqinisekisa ukhuseleko nokuthembeka kwesikhululo samandla, ukusebenza ngokufanelekileyo okuqhagamshelwe kwigridi.
Yintoni umsebenzi weBMS?
Kukho imisebenzi emininzi ye-BMS, kwaye eyona nto iphambili, eyona nto siyixhalabele kakhulu, ayikho into engaphezu kwemiba emithathu: ulawulo lwesimo, ulawulo lokulinganisela, kunye nolawulo lokhuseleko.
Umsebenzi wolawulo karhulumente weinkqubo yokulawula ibhetri
Sifuna ukwazi ukuba yintoni imeko yebhetri, yintoni i-voltage, amandla angakanani, umthamo ongakanani, kwaye yintoni intlawulo kunye nokukhupha okwangoku, kunye nomsebenzi wolawulo lwe-BMS uya kusixelela impendulo.Umsebenzi osisiseko we-BMS kukulinganisa kunye nokuqikelela iiparitha zebhetri, kubandakanywa iiparamitha ezisisiseko kunye namazwe afana nombane, okwangoku, kunye nobushushu, kunye nokubalwa kwedatha yesimo sebhetri njenge-SOC kunye ne-SOH.
Umlinganiselo weseli
Umlinganiselo wolwazi olusisiseko: Owona msebenzi usisiseko wenkqubo yolawulo lwebhetri kukulinganisa amandla ombane, angoku, kunye nobushushu beseli yebhetri, esisiseko senqanaba eliphezulu lokubala kunye nengqiqo yolawulo lwazo zonke iinkqubo zolawulo lwebhetri.
Ukubona ukuxhathisa kwe-insulation: Kwinkqubo yokulawula ibhetri, ukuxilongwa kwe-insulation yenkqubo yonke yebhetri kunye nenkqubo ye-high-voltage iyafuneka.
SOC ukubala
I-SOC ibhekisa kwiState of Charge, umthamo oseleyo webhetri.Ukubeka nje ngokulula, kukuba mangaphi amandla asele ebhetri.
I-SOC yeyona parameter ibaluleke kakhulu kwi-BMS, kuba yonke enye into isekwe kwi-SOC, ngoko ke ukuchaneka kwayo kubaluleke kakhulu.Ukuba akukho SOC echanekileyo, akukho bungakanani bemisebenzi yokukhusela enokwenza i-BMS isebenze ngokwesiqhelo, kuba ibhetri iya kuhlala ikhuselekile, kwaye ubomi bebhetri abunakwandiswa.
Iindlela zangoku zoqikelelo lwe-SOC zibandakanya indlela yombane wesekethe evulekileyo, indlela yokudibanisa yangoku, indlela yokucoca i-Kalman, kunye nendlela yenethiwekhi ye-neural.Ezokuqala ezimbini zisetyenziswa ngokuqhelekileyo.
Umsebenzi wolawulo lomncono weinkqubo yokulawula ibhetri
Ibhetri nganye ino "ubuntu" bayo.Ukuthetha ngokulinganisela, kufuneka siqale ngebhetri.Nditsho neebhetri eziveliswe ngumvelisi ofanayo kwibhetshi enye zinomjikelo wobomi bazo kwaye "ubuntu" bazo -umthamo webhetri nganye awunakufana ncam.Kukho iintlobo ezimbini zezizathu zoku kungangqinelani:
Ukungahambelani kwimveliso yeeseli kunye nokungahambelani kwi-electrochemical reactions
ukungangqinelani kwemveliso
Ukungahambelani kwemveliso kuqondwa kakuhle.Ngokomzekelo, kwinkqubo yokuvelisa, i-separator, i-cathode, kunye nezixhobo ze-anode azihambelani, okubangela ukungahambisani nomthamo webhetri jikelele.
Ukungahambelani kwe-Electrochemical kuthetha ukuba kwinkqubo yokutshaja kunye nokukhupha ibhetri, nokuba ukuveliswa kunye nokulungiswa kweebhetri ezimbini ziyafana, indawo yokushisa ayinakuze ihambelane ngexesha le-electrochemical reaction.
Siyazi ukuba ukutshaja kakhulu kunye nokukhupha ngaphezulu kunokwenza umonakalo omkhulu kwibhetri.Ngoko ke, xa ibhetri B igcwaliswe ngokupheleleyo xa itshaja, okanye i-SOC yebhetri B sele iphantsi kakhulu xa ikhutshwa, kuyimfuneko ukuyeka ukutshaja nokukhupha ukukhusela ibhetri B, kwaye amandla ebhetri A kunye nebhetri C ayinakusetyenziswa ngokupheleleyo. .Oku kubangela ukuba:
Okokuqala, Umthamo osebenzisekayo wepakethi yebhetri uncitshisiwe: amandla ebhetri A kunye no-C ebenokuwasebenzisa, kodwa ngoku akukho ndawo yokunyanzelwa ukuba unakekele i-B, njengabantu ababini kunye nemilenze emithathu ibopha ubude kunye nentambo. bafutshane kunye, kwaye amanyathelo omntu omde acotha.Awukwazi ukwenza imitsi emikhulu.
Okwesibini, Ubomi bepakethi yebhetri buncitshisiwe: i-stride incinci, inani lamanyathelo afunekayo ukuba lihambe lingaphezulu, kwaye imilenze ikhathele ngakumbi;umthamo uyancitshiswa, kwaye inani lemijikelo ekufuneka ihlawulwe kwaye ikhutshwe iyanda, kwaye ukuthomalaliswa kwebhetri nako kukhulu.Ngokomzekelo, iseli enye yebhetri inokufikelela kwimijikelezo ye-4000 phantsi kwemeko ye-100% yokuhlawula kunye nokukhutshwa, kodwa ayikwazi ukufikelela kwi-100% ekusetyenzisweni kwangempela, kwaye inani lemijikelezo akufanele lifike kumaxesha e-4000.
Kukho iindlela ezimbini eziphambili zokulinganisa i-BMS, ukulinganisa okwenziwayo kunye nokulinganisa okusebenzayo.
Ixesha langoku lokulinganisa i-passive lincinci, njenge-equalization ye-passive enikezelwa yi-DALY BMS, ene-balanced current ye-30mA kuphela kunye nexesha elide lokulinganisa umbane webhetri.
I-bancing current esebenzayo inkulu ngokwentelekiso, njengeibhalansi esebenzayoiphuhliswe yi-DALY BMS, efikelela kwi-bancing current ye-1A kwaye inexesha elifutshane lokulinganisa ombane webhetri.
Umsebenzi wokhuseleko weinkqubo yokulawula ibhetri
Imonitha ye-BMS ihambelana nehardware yesixokelelwano sombane.Ngokweemeko ezahlukeneyo zokusebenza kwebhetri, yahlulwe ngamanqanaba ahlukeneyo eempazamo (iimpazamo ezincinci, iimpazamo ezinzulu, iimpazamo ezibulalayo), kwaye amanyathelo ahlukeneyo okusebenza athathwa phantsi kwamanqanaba ahlukeneyo eempazamo: isilumkiso, umda wamandla okanye ukusika amandla ombane aphezulu ngokuthe ngqo. .Iimpazamo ziquka ukufunyanwa kwedatha kunye neempazamo ezibonakalayo, iziphene zombane (iinzwa kunye nee-actuators), iimpazamo zonxibelelwano, kunye neempazamo zesimo sebhetri.
Umzekelo oqhelekileyo kukuba xa ibhetri igqithise kakhulu, i-BMS igweba ukuba ibhetri igqithise kakhulu ngokusekelwe kwiqondo lokushisa eliqokelelweyo, kwaye ke isiphaluka esilawula ibhetri sinqanyuliwe ukwenza ukhuseleko lokufudumala kunye nokuthumela i-alamu kwi-EMS nakwezinye iinkqubo zokulawula.
Kutheni ukhetha i-DALY BMS?
