Intshayelelo:
Ngamagama alula, ukulinganisa ngumndilili wokulinganisa umbane. Gcina i-voltage yeibhetri ye-lithium packiyahambelana. Ulungelelaniso lwahlulwe lwaba lulungelelaniso olusebenzayo kunye nokulinganisa okungenziwayo. Ke ngoko yintoni umahluko phakathi kokulinganisa okusebenzayo kunye nokulinganisa okungahambiyo kwebhodi yokukhusela ibhetri ye-lithium? Makhe sijonge nge-Heltec Energy.
Ukulinganisa okusebenzayo kwebhodi yokukhusela ibhetri ye-lithium
Ukulinganisa okusebenzayo kukuba intambo ene-voltage ephezulu yongezelela amandla kwintambo ene-voltage ephantsi, ukuze amandla angachithwa, umbane ophezulu unokuthotywa, kwaye umbane ophantsi unokuxhaswa. Olu hlobo lwe-bancing current esebenzayo lunokukhetha ubungakanani bangoku bokulinganisa ngokwakho. Ngokusisiseko, i-2A isetyenziswa ngokuqhelekileyo, kwaye kukho ezinkulu ezine-10A okanye ngaphezulu.
Ngoku izixhobo ezisebenzayo zokulinganisa kwiimarike ngokusisiseko zisebenzisa umgaqo we-transformer, uxhomekeke kwiichips ezibizayo zabavelisi be-chip. Ukongeza kwi-bancing chip, kukho kwakhona amacandelo e-peripheral abizayo afana ne-transformers, enkulu ngobukhulu kunye neendleko eziphezulu.
Umphumo wokulinganisa okusebenzayo ubonakala kakhulu: ukusebenza kakuhle okuphezulu, amandla angaphantsi aguqulwa kwaye angachithiswanga ngendlela yokushisa, kwaye ilahleko kuphela yi-coil ye-transformer.
Ukulinganisa okwangoku kunokukhethwa kwaye isantya sokulinganisa sikhawuleza. Ukulinganisa okusebenzayo kuyinkimbinkimbi kwisakhiwo kunokulinganisa i-passive, ngakumbi indlela ye-transformer. Ixabiso le-BMS enomsebenzi wokulinganisa osebenzayo liya kuba phezulu kakhulu kunelo lokulinganisa okwenziwayo, nto leyo ekwathiya umda wokukhuthaza ulungelelwaniso olusebenzayo.BMS.
Ukulinganisa okungahambiyo kwebhodi yokukhusela ibhetri ye-lithium
I-Passive balancing yenziwa ngokusisiseko ngokudibanisa izixhasi zokukhupha. Umtya we-high-voltage weeseli ukhutshwa ngendlela yokutshatyalaliswa kobushushu kwindawo ejikelezileyo, ukuphumeza umphumo wokupholisa i-resistor. Ukungalungi kukuba ukukhutshwa kusekelwe kwintambo ye-voltage ephantsi kakhulu, kwaye kukho umngcipheko womngcipheko xa utshaja.
I-Passive balancing isetyenziswa ikakhulu ngenxa yeendleko zayo eziphantsi kunye nomgaqo-nkqubo olula wokusebenza; i-disadvantage yayo kukuba ilungelelaniswa ngokusekelwe kumandla aphantsi, kwaye ayikwazi ukuncedisa intambo ye-voltage ephantsi, okubangela inkunkuma yamandla.
Umahluko phakathi kolungelelwaniso olusebenzayo kunye nokulinganisa okwenziwayo
I-Passive balancing ifanelekile kumthamo omncinci, i-low-voltageiibhetri ze-lithium, ngelixa ukulinganisa okusebenzayo kulungele i-high-voltage, amandla amakhulu e-lithium ibhetri yezicelo zokupakisha.
Ubuchwephesha bokutshaja obuqhelekileyo obusetyenziswayo bubandakanya ukutshaja rhoqo kwe-shunt resistor balancing, ukutshaja kwe-shunt resistor balancing, ukutshaja okuphakathi kwebhetri ukulinganisa ukulinganisa, ukutshintshwa kwe-capacitor balancing ukutshaja, i-buck converter balancing ukutshaja, i-inductor balancing ukutshaja, njl. Xa utshaja iqela le-lithium ibhetri series, ibhetri nganye kufuneka ihlawulwe ngokulinganayo, kungenjalo ukusebenza kunye nobomi yeqela lonke lebhetri liya kuchaphazeleka ngexesha lokusetyenziswa.

Umgaqo osisiseko wokulinganisa okungenziwayo kukuphumeza umphumo wokulinganisa ngokumosha amandla agqithisileyo. Ngesiqhelo, amandla angaphezulu kwipakethi yebhetri egqithileyo aguqulwa abe bubushushu ngesichasi, ukuze amandla ombane ebhetri ahlale engaguquki. Inzuzo kukuba i-passive balancing circuit ilula kwaye uyilo kunye neendleko zokuphunyezwa ziphantsi. Kwaye iteknoloji yokulinganisa i-passive ikhulile kakhulu kwaye isetyenziswe ngokubanzi kwiindleko eziphantsi kunye nezincinciiipakethi zebhetri.
Ukungalungi kukuba kukho ilahleko enkulu yamandla ngenxa yokuguqulwa kwamandla ombane kubushushu ngokuxhathisa. Ukusebenza okuphantsi, ngakumbi kwiipakethi zebhetri ezinomthamo omkhulu, inkunkuma yamandla ibonakala ngakumbi, kwaye ayifanelekanga kwizicelo ezinkulu zebhetri ezisebenza kakhulu. Kwaye ngenxa yokuba amandla ombane aguqulwa abe bubushushu, anokubangela ukuba ipakethi yebhetri ishushu kakhulu, ichaphazela ukhuseleko kunye nobomi benkqubo iyonke.
Ulungelelwaniso olusebenzayo lufezekisa ukulungelelanisa ngokugqithisela amandla ombane agqithisileyo ukusuka kwiibhetri ezinombane ophezulu ukuya kwiibhetri ezinombane ophantsi. Le ndlela ilungelelanisa ngokubanzi unikezelo lwamandla phakathi kweebhetri ngokutshintsha izixhobo zombane, iziguquli ze-buck-boost okanye amanye amacandelo e-elektroniki. Inzuzo iphezulu kakhulu: amandla awachithwanga, kodwa alungelelaniswe ngokudluliselwa, ngoko akukho kulahleka kobushushu, kwaye ukusebenza kakuhle ngokuqhelekileyo kuphezulu (ukuya kuma-95% okanye ngaphezulu).
Ukonga amandla: Kuba akukho nkcitho yamandla, ifanelekile kumthamo omkhulu, ukusebenza okuphezuluibhetri ye-lithiumIinkqubo kwaye inokwandisa ubomi benkonzo yepakethi yebhetri. Isebenza kwiipakethi ezinkulu zebhetri: Ukulinganisa okusebenzayo kulungeleka ngakumbi kwiipakethi zebhetri ezinomthamo omkhulu, ngakumbi kwiimeko ezifana neenqwelo zombane kunye neenkqubo zokugcina amandla, kwaye kunokuphucula kakhulu ukusebenza kwenkqubo kunye nokunyamezela.
Ukungalungi kukuba ukuyila kunye nokuphunyezwa kokulinganisa okusebenzayo kunzima, ngokuqhelekileyo kufuna amacandelo amaninzi e-elektroniki, ngoko ke ixabiso liphezulu. Ubunzima bobugcisa: Ukulawulwa ngokuchanekileyo kunye noyilo lwesekethe kuyadingeka, okunzima kwaye kunokunyusa ubunzima bophuhliso nokugcinwa.
