Izinhlelo zokusebenza zezimboni nezentengiselwano zanamuhla zithembela kakhulu ekucushweni kwamandla e-lithium-ion okuyinkimbinkimbi kanye ne-lead-acid ekusebenzeni kwamandla. Umbono ovamile oyiphutha kubunjiniyela bokugcina amandla ukuthi iphakethe lebhethri elinamandla aphezulu lisebenza nje njengentambo elula exhunywe ochungechungeni lwamaseli ngamanye. Empeleni, amaseli e-electrochemical ngokwemvelo abonisa ukwehluka okucashile ekumelaneni kwangaphakathi, amazinga okuzikhipha, kanye namakhono okusebenza ngenxa yokubekezelelana kokukhiqiza kanye ne-gradients yokushisa yendawo. Ukuze kuncishiswe lokhu kungafani, abaqhubi bezimboni basebenzisa imishini ekhethekile yokuphatha amandla eyakhiwe yiAmandla eHeltec unjiniyela ohamba phambili wezinhlelo zokulinganisa amaseli. Ngemijikelezo eminingi yokushaja nokukhipha, umehluko omncane wamaseli ngamanye uyakhula, okubangela into eyaziwa ngokuthi "umphumela webhareli," lapho iseli elibuthakathaka kakhulu lilawula umthamo ophelele ongasetshenziswa futhi likhawulele ukusebenza kwenhlangano yonke. Ngenkathi izinhlelo zokuphepha ezijwayelekile ziqapha lokhu kulungiselelwa, i-equalizer yebhethri ekhethekile isebenza njengengxenye ebalulekile yokulungisa nokusebenza eyenzelwe ukuqeda lokhu kuhlukahluka kwangaphakathi, ukuqinisekisa ukusebenza kahle kwesikhathi eside.
Izindima Ezihlukile Zamamojula Okulinganiselayo Nezinhlelo Zokuphatha Ibhethri
Ukuze kuthuthukiswe ama-power array amakhulu, kubalulekile ukuhlukanisa imingcele ethile yokusebenza ye-standard Battery Management System (BMS) kuleyo ye-balancing module ezinikele. I-BMS evamile isebenza ngokuyinhloko njengendlela yokuphepha nokuvikela, iqapha amapharamitha afana nokushaja ngokweqile, ukukhipha ngokweqile, ugesi ongaphezu kwamandla, kanye nezimo ze-short-circuit ukuvimbela ukwehluleka okubi kakhulu. Kodwa-ke, amakhono okulinganisa angaphakathi amayunithi amaningi e-BMS ajwayelekile awasebenzi, athembele kuma-resistor amancane ukuze asuse amandla amaningi njengokushisa, ngokuvamile anqunyelwe kuma-current aphansi angama-milliamperes angu-30 kuya kwangu-50.
Ngokuphambene nalokho, imodyuli yokulinganisela yangaphandle isebenza njenge-co-processor eqondiswe kakhulu, ethuthukisa ukusebenza esebenza eceleni kwe-BMS evikelayo. Esikhundleni sokushintsha uhlelo lokuphepha, i-balancer ezinikele igxila kuphela ekuqedeni ukungafani kwamandla kagesi kuwo wonke amaseli axhunywe ochungechungeni. Ngokuqhubeka nokudlulisa amandla kusuka kumaseli ane-voltage ephezulu kuya kumaseli ane-voltage ephansi, imodyuli igcina amazinga afanayo e-state-of-charge kulo lonke iphakethe. Lokhu kuphathwa okusebenzayo kuvimbela amaseli ngamanye ukuthi afinyelele ngaphambi kwesikhathi imingcele yokusika kwamandla kagesi aphansi, ngaleyo ndlela avule amandla abengeke afinyeleleke ngenxa yokuwohloka kwamaseli asendaweni.
Izindlela Zokusebenza kanye Nokuqinisekiswa Kokusebenza Kokulingana Okusebenzayo
Ubuchwepheshe bokulungisa obuthuthukisiwe, njengemishini ekhethekile ethuthukiswe yiChengdu Heltec Energy Technology Co., Ltd., isebenzisa ukudluliselwa kwamandla asebenzayo okusebenza kahle kakhulu ukubhekana nokungahambisani kwamaseli. Esikhundleni sokuchitha amandla amaningi njengamandla okushisa, ama-equalizer asebenzayo athuthukisiwe asebenzisa ama-microcontroller ahlanganiswe nezakhiwo zokudlulisa amandla ezisebenza kahle noma ezisebenzisa amandla ukuze aphinde afake ishaja ngendlela eguquguqukayo kulo lonke iphakethe.
Ukuhlaziywa kwezinhlelo zokulinganisela ezizimele ezivela ku-Heltec Energy kugqamisa izindlela eziningana zobuchwepheshe eziqondile ezifaka isandla ekuvuselelweni kwephakethe okuqinisekisiwe:
● Ukuqapha Okunembe Kakhulu:Ukuhlanganiswa kwama-microcontroller e-Microchip asheshayo kwenza kube lula ukuthola i-voltage yesikhathi sangempela ngokunemba kwesampula okungu-1 millivolt kububanzi obubanzi bokulinganisa obungu-1V kuya ku-5V. Lokhu kulungiswa okunembile kuvumela uhlelo ukuthi luthole ukuphambuka kwe-micro-volt ngaphambi kokuba kukhuphuke kube yizithiyo ezibalulekile zokusebenza.
● Ukudluliselwa Kwamandla Okungachithi:Ngokusebenzisa amasekethe athuthukisiwe ashukumisayo noma anamandla, lezi zinhlelo zenza kube lula ukuhamba okuqhubekayo kokulinganisa okufinyelela ku-15 amperes kumamodeli athile. Okubaluleke kakhulu, le ndlela isebenza ngokuzimela endaweni eseduze kweseli, okusho ukuthi amandla angadluliselwa kahle kusuka kuseli lokuqala kuya kuseli lokugcina ngentambo ende yochungechunge ngaphandle kokuqongelela ukushisa kwendawo.
● I-Chemistry Ehlukahlukene Nokuhambisana Kwesakhiwo:Amathuluzi okulinganisa esimanje ahlinzeka ngokusekelwa kwendabuko kwezindawo eziyinkimbinkimbi ezisukela ku-2S kuya ku-24S noma ngisho nokulungiselelwa kwe-32S. Lokhu kuguquguquka kuqinisekisa ukuhambisana okungenamthungo kumaphrofayili amaningi amakhemikhali, kufaka phakathi i-Lithium Nickel Manganese Cobalt Oxide (NCM), i-Lithium Iron Phosphate (LFP), kanye ne-Lithium Titanate (LTO).
● Izici Zokusebenza Nokuphepha Kwemodi Eningi:Amamodeli athuthukile afaka izindlela zokulinganisa ezizenzakalelayo, ezenziwe ngesandla, noma eziqondene nokushaja, ezihambisana nama-alamu okuvala ngokuzenzakalela kanye nama-alamu azwakalayo lapho umsebenzi usuqediwe. Ukuqina komzimba kuthuthukiswa ngezingubo ezikhethekile zokuvikela ezivikela amasekethe angaphakathi emswakama, uthuli, kanye nokugqwala kwamakhemikhali, kuyilapho izikrini ze-LCD ezihlanganisiwe kanye nezixhumi zohlelo lokusebenza ezingenantambo zivumela ukulandelwa kokuxilonga okukude.
Ukusebenzisa ukulingana okuqondiwe kunciphisa ngqo ukuwohloka kwesakhiwo sephakethe. Ukuqeda ukungalingani kwamandla kagesi kulungisa isimo sokushaja kuwo wonke amaseli, kubuyisa ngempumelelo amandla avaliwe ngenxa yokunqanyulwa kwamandla kagesi ngaphambi kwesikhathi. Lokhu kukhulisa ngqo ukujula kokukhishwa, kunciphisa ukuhlukana kokumelana kwangaphakathi, futhi kwehlise ijubane lokushabalala kwamandla kagesi, ngaleyo ndlela kwandise isikhathi sokusebenza sempahla yezimboni.
Izikhathi Zokusetshenziswa Ezisekelwe Ezigabeni Zokuwohloka Kwamakhemikhali
Ukunquma isikhathi esifanele sokuhlanganisa ibhalansi yebhethri ezinikele kuncike kakhulu esigabeni esithile sokusebenza kanye nezici zokucindezeleka kwemvelo zesistimu yamandla. Emaphaketheni ebhethri asanda kuhlanganiswa asebenza ngemijikelezo yokusebenza emifushane, ephansi kokucindezeleka, ukuhlukahluka kwamaseli angaphakathi ngokuvamile kuncane, okuvumela uhlelo oluyinhloko ukuphatha ukuzinza okwesikhashana ngaphandle kokungenelela kwangaphandle okusheshayo.
Kodwa-ke, idatha yasensimini ehlanganiswe yiChengdu Heltec Energy Technology Co., Ltd. ikhombisa ukuthi ukuhlanganiswa kunconywa kakhulu ngemuva kwezinyanga eziyisithupha zenkonzo eqhubekayo, noma lapho ukungafani kwamaseli ngamanye kulinganiswa kudlula ama-millivolt angu-30. Ukulungiswa kuba okuphuthumayo ikakhulukazi ekusetshenzisweni okunzima njengamanethiwekhi okugcina amandla azinzile, izinsiza zikagesi ezisindayo, kanye nemikhumbi yokuthutha kagesi. Ngaphezu kwalokho, lapho izinqubo zokulungisa zidinga ukuxuba amaseli amasha nezingxenye ezindala, ezingalingani, izinhlaka zokulinganisela ezingasebenzi ziyahluleka ukucubungula umehluko omkhulu wamandla kagesi. Kulezi zimo ezifunwa kakhulu, ukulingana okusebenzayo kuvimbela ukuwohloka okusheshayo kokushisa kwendawo kanye nokuyeka umsebenzi ngaphambi kwesikhathi.
Isiphetho
Amamojula okulinganisela anikezelwe asebenza njengengqalasizinda ebalulekile yokwandisa ukuhambisana, ukuphepha, kanye nokuphila isikhathi eside ekufakweni kwamabhethri ezimbonini. Ngokunciphisa ngenkuthalo ukungafani kwamaseli okuholela ekulahlekelweni kwamandla kusenesikhathi, lezi zinhlelo zivikela ukutshalwa kwezimali okukhulu kwezimali kubuchwepheshe bamandla. Ukukhetha ihadiwe yokulinganisa esebenzayo efanele kudinga ukufanisa ukucushwa kochungechunge oluthile kanye nekhemistri eyisisekelo yephakethe lebhethri namathuluzi okulungisa aqondiwe. Ukuze uthole imininingwane yobuchwepheshe ephelele, imininingwane yobunjiniyela besakhiwo, kanye nemibuzo yomkhiqizo mayelana nezixazululo ezikhethekile zokuphathwa kwamandla, vakashela iphothali yezinsiza ezisemthethweni ku-https://www.heltec-energy.com/.
