Intshayelelo:
Uvavanyo lokutshaja kunye nokukhutshwa kwebhetriyinkqubo yovavanyo esetyenziselwa ukuvavanya izalathisi ezibalulekileyo ezifana nokusebenza kwebhetri, ubomi bayo, kunye nokusebenza kakuhle kwetshaja kunye nokukhupha. Ngovavanyo lwetshaja kunye nokukhupha, sinokuqonda ukusebenza kwebhetri phantsi kweemeko ezahlukeneyo zokusebenza kunye nokonakala kwayo ekusetyenzisweni kwayo ixesha elide. Okulandelayo, landela i-heltec ukuze ufunde malunga novavanyo lwetshaja kunye nokukhupha ibhetri.
Uvavanyo lokuTshaja nokuKhutshwa kweBhetri:
Izixhobo zovavanyo: Iingcaliizixhobo zokuvavanya ukutshaja nokukhupha itshajaziyafuneka, kuquka abavavanyi bebhetri, iitshaja, ii-dischargers, kunye neenkqubo zokurekhoda idatha. Ezi zixhobo zinokulawula ngokuchanekileyo umsinga wokutshaja, i-voltage, kunye nomsinga wokutshaja. Vavanya ibhetri: Khetha ibhetri eza kuvavanywa kwaye uqinisekise ukuba ibhetri ikwimeko yokungatshajwa okanye yokutshajwa ngokupheleleyo. Iimeko zendalo: Ubushushu bunempembelelo enkulu ekusebenzeni kwebhetri. Uvavanyo kufuneka lwenziwe kubushushu obuchaziweyo, ngokubanzi ngama-25°C.
Indlela yovavanyo:
Uvavanyo lokutshaja rhoqo kunye nokukhutshwa: Sebenzisa umbane ongaguqukiyo ukutshaja nokukhupha ibhetri, enokulinganisa umthamo webhetri, ukusebenza kakuhle kokutshaja nokukhupha kunye nobomi bomjikelo. Xa utshaja, sebenzisa umbane ongaguqukiyo ukutshaja ukuya kumbane ophezulu webhetri, njengebhetri ye-lithium ukuya kwi-4.2V; xa ukhupha, sebenzisa umbane ongaguqukiyo ukutshaja ukuya kumbane ophantsi, njengebhetri ye-lithium ukuya kwi-2.5V.
Uvavanyo lokutshaja i-voltage rhoqo: Isetyenziswa rhoqo ekutshajeni ibhetri ye-lithium ukuze kuthintelwe ukutshaja kakhulu. Qala ngokutshaja nge-constant current, kwaye emva kokufikelela kwi-voltage emiselweyo, qhubeka utshaja kule voltage ude i-current yehle iye kwixabiso elimiselweyo.
Uvavanyo lokukhupha umbane rhoqo: Khupha ibhetri ngamandla angaguqukiyo de kufikelelwe kwi-voltage encinci yebhetri, ukuze kuvavanywe ukusebenza kokukhupha ibhetri phantsi kwamandla angaguqukiyo.
Uvavanyo lobomi bomjikelo:Phinda umjikelo wokutshaja nokukhupha ibhetri de umthamo webhetri wehle uye kwixabiso elithile, njenge-80% yomthamo wokuqala, ukuvavanya ubomi bomjikelo webhetri. Kubalulekile ukuseta imiqathango yokuphela kwenani lemijikelo yokutshaja nokukhupha ibhetri okanye ukubola komthamo, kwaye urekhode utshintsho lomthamo womjikelo ngamnye.
Uvavanyo lokutshaja ngokukhawuleza kunye nokukhutshwa:Sebenzisa amandla aphezulu okutshaja nokukhupha ibhetri ngokukhawuleza ukuze uvavanye amandla okutshaja nokukhupha ibhetri ngokukhawuleza kunye nokubola kokusebenza kwayo. Itshaja ngokukhawuleza ngombane ophezulu, kwaye xa i-voltage emiselweyo ifikeleleka, itshintshela ngokukhawuleza kwinkqubo yokukhupha ibhetri.
Izalathi zovavanyo:
Ubungakanani:libhekisa kubungakanani bombane obunokukhutshwa yibhetri phantsi kweemeko ezithile zokukhupha, ngesiqhelo kwiiyure ze-ampere (Ah) okanye iiyure ze-kilowatt (kWh), nto leyo ebonisa ngokuthe ngqo amandla okugcina amandla ebhetri.
Ukumelana kwangaphakathi:Ukumelana okufumanekayo xa umbane udlula kwibhetri, kwi-milliohms (mΩ), kubandakanya ukumelana kwangaphakathi kwe-ohmic kunye nokumelana kwangaphakathi kwe-polarization, okuchaphazela ukusebenza kakuhle kokutshaja nokukhupha ibhetri, ukuveliswa kobushushu, kunye nobomi bayo.
Uxinano lwamandla:yahlulwe ngobunzima bobunzima bobunzima kunye nobuninzi bobunzima bomthamo wombane, nto leyo ebonisa amandla anokukhutshwa yibhetri ngobunzima beyunithi nganye okanye ngomthamo weyunithi nganye, kunye neeyunithi ezisisiseko zeWh/kg kunye neWh/L, ngokwahlukeneyo, ezichaphazela umgama wokuqhuba wezithuthi zombane kunye nezinye izixhobo kunye noyilo olukhaphukhaphu lwesithuthi siphela.
Izinga lokutshaja kunye nokukhupha:Ibonisa umlinganiselo wetshaja kunye nomsinga wokukhupha ibhetri, ngo-C, ebonisa amandla ebhetri okutshaja nokukhupha ngokukhawuleza.
Izixhobo zovavanyo lokutshaja nokukhupha ibhetri:
Umvavanyi wokutshaja kwebhetri kunye nokukhuphaingenza uvavanyo lokutshaja olunzulu kunye nokukhupha kwiintlobo ezahlukeneyo zeebhetri, idibanisa ukulinganisa okuchanekileyo, ulawulo olukrelekrele kunye nemisebenzi yohlalutyo lwedatha, inokulinganisa iimeko zokusebenza zokwenyani, kwaye ivavanye ngokupheleleyo umthamo webhetri, ukumelana kwangaphakathi, ukusebenza kakuhle kwetshaja kunye nokukhupha, ubomi bomjikelo kunye nezinye izalathisi.
IHeltec ineentlobo ngeentlobo zezixhoboizixhobo zokuvavanya ukutshaja kwebhetri kunye nokukhupha umbane, efikelelekayo nesemgangathweni olungileyo, ungakhetha imveliso ekufaneleyo ngokwevolthi yamandla ebhetri yakho, njl.njl., ukubonelela ngovavanyo olufanelekileyo lwedatha yebhetri yakho.
