Kutheni ibhetri ye-lithium-ion enomthamo oqhelekileyo we-100Ah ngamanye amaxesha inika kuphela i-70Ah yamandla okwenyani ngexesha lokusebenza? Isizathu esiyintloko sale ngxaki yokusilela komthamo asisoloko siyinto embi kakhulu; endaweni yoko, isoloko iqhutywa kukungalingani kwamandla ombane angaphakathi phakathi kweeseli nganye nganye. Njenge-stave emfutshane kwibharele yomthi ilawula umthamo wamanzi opheleleyo enokubamba, eyona seli ibuthathaka kuluhlu lweenkqubo imisela amandla asebenzisekayo ebhetri yonke. Xa umahluko wombane phakathi kweeseli udlula i-30mV, iindlela eziqhelekileyo zokulinganisela ezidityaniswe kwiiNkqubo zoLawulo lweBhetri ezisemgangathweni (i-BMS) azinawo amandla angoku okulungisa umahluko. Phantsi kwezi meko, i-equalizer ekhethekileyo yebhetri iba sisixhobo esifanelekileyo sokulungisa ukungalingani kweeseli zebhetri. Ukujongana nalo mngeni wokusebenza,IChengdu Heltec Energy Technology Co., Ltd.Ibonelela ngetekhnoloji yokulinganisela ephucukileyo kunye nezixhobo zokulungisa ezenzelwe ukujolisa nokulungisa iiseli ezingalungelelananga kakuhle, ukuvula amandla alinganiselweyo, kunye nokubuyisela ipakethi yebhetri kumanqanaba ayo okusebenza akhiweyo.
Imida Yokusebenza Yokulinganisela Okungasebenziyo Ekugcinweni Nokulungiswa
Iinkqubo zokulinganisela ezingasebenziyo ezisemgangathweni zisebenza ngokukhupha amandla agqithisileyo kwiiseli ze-voltage ephezulu njengobushushu ngokusebenzisa ii-shunt resistors. Nangona olu yilo lwanele ukugcina iiseli ezisempilweni nezihambelanayo ngexesha lokusebenza okuqhelekileyo, alubonakali lwanelanga xa umahluko we-voltage udlula i-50mV okanye xa iiseli ezindala zixutywa nezintsha ngexesha lokwakhiwa kwakhona kwepakethi engaphelelanga. Ukulinganisela okungasebenziyo kusebenza kwimijelo ephantsi kakhulu, ngesiqhelo phakathi kwe-30mA kunye ne-100mA, oko kuthetha ukuba ukusombulula umahluko omkhulu we-capacity kwiipakethi ze-capacity ephezulu kungathatha iintsuku, ukuba akunjalo iiveki.
Ukulungisa oku kungalingani okukhulu, iindawo zolondolozo zobungcali zisebenzisa izixhobo ezizimeleyo zomgangatho wolondolozo endaweni yokuxhomekeka kwizixhobo zangaphakathi eziqhelekileyo. I-Chengdu Heltec Energy Technology Co., Ltd. ijongana nalo mceli mngeni weshishini ngobunjineli obusebenza nzima.isilinganisi sebhetriizixhobo ezidibanisa umlinganiselo ochanekileyo we-voltage, ukuxilongwa kokumelana kwangaphakathi, kunye nokudluliselwa kwamandla aphezulu. Endaweni yokuchitha amandla njengobushushu, ezi zilinganisi zolondolozo zikhupha amandla kwiiseli ezine-voltage ephezulu kwaye ziwasasaze ngokuthe ngqo kwiiseli ezine-voltage ephantsi, zilungisa ukwahluka okukhulu kweeseli ngexesha elifanelekileyo lokusebenza.
Iinkcukacha zoBugcisa kunye noYilo loBunjineli
Ukuchaneka kwezixhobo zokulungisa ezikhethekileyo kuxhomekeke ngqo kuyilo lolawulo kunye nesisombululo sokulinganisa senkqubo. I-Heltec Energy yakha izixhobo zayo zokuxilonga kunye nokugcina isebenzisa iiyunithi ezinkulu ze-microcontroller (MCUs) ezikhawulezayo nezivela kwiMicrochip Technology Inc. Ezi prosesa zivumela ukufunyanwa kwe-voltage yexesha langempela kwiiseli nganye nganye ezinoluhlu lokulinganisa oluvela kwi-1V ukuya kwi-5V ngeseli nganye kunye novavanyo lokuchaneka lwe-±1mV. Inkqubo yolawulo lwangaphakathi ichonga ngokuzenzekelayo uqwalaselo lweepakethe zebhetri ezixhunyiweyo, ixhasa uqwalaselo oluvela kwi-2S ukuya kwi-24S, kunye neemodeli ezithile eziphambili ezikhulisa amandla ukuya kwi-32S. Olu lwakhiwo lwe-multi-chemistry luvumela isixhobo esinye ukuba sisebenzele iikhemistri zeLithium Nickel Manganese Cobalt Oxide (NCM), iLithium Iron Phosphate (LFP), kunye neLithium Titanate (LTO) ngaphandle kokufuna uhlengahlengiso lwesakhiwo ngesandla.
Umsebenzi ophambili wezonyango wezixhobo uxhomekeke kwindlela yokulinganisela amandla enikezela ngombane oqhubekayo ukuya kuthi ga kwi-15A okanye kwi-25A kuxhomekeke kuyilo oluthile lwemodeli. Ngokungafaniyo neebhodi zebhalansi ezisebenzayo ezisisiseko apho umbane uphuma khona njengoko ii-voltage zeseli zidibana, izixhobo zeHeltec Energy zigcina udluliselo oluzinzileyo, oluphezulu olusebenza ngokuzimeleyo ngaphandle komsantsa we-voltage. Iingcali zinokukhetha kwiindlela ezintathu zokusebenza nge-interface: ukulinganisa ngesandla, ukulinganisa ngokuzenzekelayo, okanye ukulinganisa okuncediswa yitshaja. Ulwakhiwo olubonakalayo luquka iphaneli yokulawula enelungelo lobunikazi elungisa phakathi kwe-0 kunye ne-45 degrees ukuze ihambelane neendawo zokusebenza ezimiyo okanye ezihleli phantsi, ujongano olupheleleyo lwe-touch oluyi-intshi ezi-7, kunye neqhosha lokumisa elingxamisekileyo elizinikeleyo.
Ukuze kukhuseleke ngexesha lokudluliselwa kwamandla aphezulu, le circuitry ibandakanya ukhuseleko lwe-overvoltage yeseli enye kunye nezilumkiso zehardware zexesha langempela ze-reverse polarity, i-total pack overvoltage, iimeko ze-undervoltage, kunye ne-internal metal-oxide-semiconductor field-effect transistor (MOSFET). Uqwalaselo oluphezulu, olufana nemodeli ye-HT-CJ32S25A, lukwabandakanya izibonisi ze-liquid-crystal (LCD) ezikwibhodi ukubonisa ii-voltages zomtya ngamnye, i-cumulative pack voltage, i-active balancing current, kunye namaqondo obushushu angaphakathi kunye noqhagamshelo lwe-app ye-Wi-Fi edibeneyo yokurekhoda idatha ekude.

3. Izixhobo zoMbane zeMizi-mveliso kunye noGrid-Scale Energy Storage
Iiseti zokugcina amandla ezindlu, izitishi zonxibelelwano, kunye nezibonelelo zamandla elanga zixhomekeke kwiibhetri ezinkulu, ezineetshaneli ezininzi. Ukungalingani kwezi zinto zifakelwayo kunokunciphisa imbuyekezo yemali kutyalo-mali kwiinkqubo zamandla avuselelekayo. Iinkqubo zolondolozo lweendlela ezininzi zisetyenziselwa ukwenza ukusebenza kweeseli ezijikelezayo kunye nokulinganisela kwamandla aphezulu kwiipakethi ezinkulu, ukubuyisela ukuhambelana kwenkqubo kunye nokuzinzisa iziseko zamandla okuxhasa amashishini.
Ukuphuculwa kokusebenza kunye nolwandiso lobomi
Ngokudibanisa uvavanyo lokuxilonga kunye nokusasazwa kwamandla asebenzayo, izixhobo zokulinganisela ezikhethekileyo zitshintsha indlela impilo yebhetri elawulwa ngayo kwiindawo zokusebenzela zobungcali. Ukulungisa ukulungelelaniswa kwe-voltage yeseli ukuya kwi-1mV ukunyamezela ngokuthe ngqo kuthintela iiseli nganye ukuba zingafikeleli kwimida yazo yokusika i-voltage esezantsi okanye ephezulu ngaphambi kwexesha. Olu lungelelwaniso lokulinganisela lunceda ababoneleli bezothutho, ukulungisa iinethiwekhi zeziseko zophuhliso, kunye neendawo zokwenza imveliso zibuyisele umthamo wepakethi elahlekileyo, ukunciphisa iindleko zewaranti iyonke, kunye nokuqinisekisa uzinzo oluqhubekayo lweenkqubo zokugcina amandla. Ukukhetha ukuseta ukulinganisela ngokuchanekileyo ngokusekelwe kwiikhemistri ezithile zeeseli kunye noqwalaselo lwechungechunge kuvumela abaqhubi ukuba bagcine iiasethi zehardware kwaye bandise ubomi bokusebenza beepakethi zebhetri ze-lithium zoshishino.
