1. Amandla (iyunithi: Ah)
Lena ipharamitha wonke umuntu akhathazeke kakhulu ngayo. Umthamo webhethri ungenye yezinkomba zokusebenza ezibalulekile zokulinganisa ukusebenza kwebhethri, okubonisa ukuthi ngaphansi kwezimo ezithile (izinga lokuphuma, izinga lokushisa, i-voltage yokunqamula, njll.) ibhethri likhipha inani likagesi (ukuhlolwa kokukhipha kwe-JS-150D okutholakalayo) , okungukuthi, umthamo webhethri, ngokuvamile ku-amperage - amahora njengeyunithi (isifinyezo, esivezwe ngo-AH, 1A-h = 3600C). Isibonelo, uma ibhethri lingu-48V200ah, kusho ukuthi ibhethri lingagcina 48V*200ah=9.6KWh, okungukuthi, 9.6 kilowatts kagesi. Umthamo webhethri uhlukaniswe umthamo wangempela, umthamo wethiyori kanye nomthamo olinganiselwe ngokuya ngezimo ezihlukene.
Amandla angempelaibhekisela enanini likagesi ibhethri elinganikeza ngaphansi kwendlela ethile yokukhipha (izinga elithile lenhlabathi, ukuminyana okuthile kwamanje kanye ne-voltage ethile yokunqamula). Umthamo wangempela ngokuvamile awulingani nomthamo olinganiselwe, ohlobene ngokuqondile nezinga lokushisa, umswakama, izinga lokushaja kanye nokukhipha. Ngokuvamile, umthamo wangempela mncane kunomthamo olinganiselwe, ngezinye izikhathi ngisho nangaphansi komthamo olinganiselwe.
Amandla etiyethaisho inani likagesi elinikezwe yizo zonke izinto ezisebenzayo ezibamba iqhaza ekuphenduleni kwebhethri. Okungukuthi, umthamo esimweni esihle kakhulu.
Umthamo olinganiselweisho i-nameplate ekhonjiswe enjinini noma ezintweni zikagesi ezimeni zokusebenza ezilinganiselwe zingaqhubeka nokusebenza isikhathi eside. Ngokuvamile ibhekisela emandleni abonakalayo ama-transformer, amandla asebenzayo amamotho, namandla abonakalayo noma asebenzayo emishini yokulawula isigaba, ku-VA, kVA, MVA. Ekusetshenzisweni, i-geometry ye-pole plate, i-voltage yokunqanyulwa, izinga lokushisa, nezinga lokukhishwa konke kunomthelela kumthamo webhethri. Isibonelo, ebusika enyakatho, uma umakhalekhukhwini usetshenziswa ngaphandle, umthamo webhethri uzokwehla ngokushesha.
2. Ukuminyana kwamandla (iyunithi: Wh/kg noma i-Wh/L)
Ukuminyana kwamandla, ukuminyana kwamandla ebhethri, kudivayisi enikeziwe yokugcina amandla e-electrochemical, isilinganiso samandla esingashajwa kusisindo noma ivolumu yendawo yokugcina. Owokuqala ubizwa ngokuthi "ukuminyana kwamandla amakhulu", lokhu kwakamuva kubizwa ngokuthi "i-volumetric energy density", iyunithi ngokulandelana kwayo i-watt-hour/kg Wh/kg, watt-hour/litre Wh/L. Amandla lapha, amandla ashiwo ngenhla (Ah) kanye ne-voltage yokusebenza (V) ye-integrated. Uma kukhulunywa ngezinhlelo zokusebenza, imethrikhi yokuminyana kwamandla ifundisa kakhulu kunomthamo.
Ngokusekelwe kubuchwepheshe bamanje bebhethri ye-lithium-ion, izinga lokuminyana kwamandla lingafinyelelwa cishe ku-100~200Wh/kg, elisephansi futhi seliphenduke umgoqo wezinhlelo zebhethri ze-lithium-ion ezikhathini eziningi. Le nkinga iphinde yenzeke emkhakheni wezimoto zikagesi, kumthamo nesisindo kungaphansi kwemikhawulo eqinile, ukuminyana kwamandla ebhethri kunquma ububanzi bokushayela bezimoto zikagesi, ngakho-ke "ukukhathazeka kwe-mileage" leli gama eliyingqayizivele. Uma uhla lokushayela lwemoto kagesi olulodwa luzofika kumakhilomitha angu-500 (uma kuqhathaniswa nemoto evamile kaphethiloli), ukuminyana kwamandla ebhethri elilodwa kufanele kube ngu-300Wh/kg noma ngaphezulu.
Ukwenyuka kokuqina kwamandla amabhethri e-lithium-ion kuyinqubo ehamba kancane, ephansi kakhulu kunoMthetho kaMoore embonini yesifunda ehlanganisiwe, okudala umehluko phakathi kokuthuthukiswa kokusebenza kwemikhiqizo ye-elekthronikhi kanye nokwenza ngcono ukuminyana kwamandla kwamabhethri aqhubeka nokukhula ngokuhamba kwesikhathi. .
