1. Umthamo (iyunithi: Ah)
Le yiparameter ukuba wonke umntu ukhathazeke ngakumbi. Umthamo webhetri ungenye yezibonakaliso zokusebenza ezibalulekileyo zokulinganisa ukusebenza kwebhetri, ebonisa ukuba phantsi kweemeko ezithile (izinga lokukhutshwa, ubushushu, i-voltage yokuphelisa, njl. njl.) ibhetri ikhupha umthamo wombane (uvavanyo olukhoyo lwe-JS-150D) , oko kukuthi, umthamo webhetri, ngokuqhelekileyo kwi-amperage - iiyure njengeyunithi (isifinyezo, esichazwe kwi-AH, 1A-h = 3600C). Umzekelo, ukuba ibhetri yi-48V200ah, oko kuthetha ukuba ibhetri inokugcina i-48V*200ah=9.6KWh, okt, i-9.6 kilowatts yombane. Umthamo webhetri wahlulwe kumthamo wokwenene, umthamo wethiyori kunye nomthamo olinganisiweyo ngokweemeko ezahlukeneyo.
Amandla okweneneibhekisa kumthamo wombane ibhetri enokunika wona phantsi kolawulo oluthile lokukhupha (inqanaba elithile lentlenga, ingxinano ethile yangoku kunye nombane othile wokuphelisa). Umthamo wangempela ngokuqhelekileyo awulingani nomthamo olinganisiweyo, ohambelana ngokuthe ngqo nobushushu, ukufuma, ukutshaja kunye nesantya sokukhupha. Ngokubanzi, esona sikhundla sincinci kunomthamo olinganisiweyo, ngamanye amaxesha nokuba mncinci kakhulu kunomthamo olinganisiweyo.
Umthamo wethiyoriibhekisa kumthamo wombane onikiweyo zizo zonke izinto ezisebenzayo ezithatha inxaxheba kwintshukumo yebhetri. Oko kukuthi, umthamo kwindawo efanelekileyo kakhulu.
Umthamo olinganisiweyoibhekisa kwi-nameplate eboniswe kwimoto okanye kwizixhobo zombane kwiimeko zokusebenza ezilinganisiweyo zinokuqhubeka nokusebenza ixesha elide. Ngokuqhelekileyo ibhekisa kumandla abonakalayo eenguqu, amandla asebenzayo eenjini, kunye namandla abonakalayo okanye asebenzayo kwisixhobo sokulawula isigaba, kwi-VA, kVA, MVA. Ekusetyenzisweni, ijometri yepleyiti yepali, ivolthi yokuphelisa, ubushushu, kunye nenqanaba lokukhupha zonke zinefuthe kumthamo webhetri. Ngokomzekelo, ebusika enyakatho, ukuba ifowuni isetyenziswe ngaphandle, amandla ebhetri aya kuhla ngokukhawuleza.
2. Uxinzelelo lwamandla (iyunithi: Wh/kg okanye i-Wh/L)
Ubuninzi bamandla, ubuninzi bamandla ebhetri, kwisixhobo esinikiweyo sokugcina amandla e-electrochemical, umlinganiselo wamandla onokuhlawuliswa kubunzima okanye umthamo wendawo yokugcina. Eyangaphambili ibizwa ngokuba "yi-mass energy density", le yokugqibela ibizwa ngokuba "yi-volumetric energy density", iyunithi ngokulandelelana kwayo yi-watt-hour/kg Wh/kg, watt-hour/litre Wh/L. Amandla apha, ngumthamo okhankanywe ngasentla (Ah) kunye ne-voltage yokusebenza (V) yokudibanisa. Xa kuziwa kwizicelo, i-metric yoxinano lwamandla ifundisa ngakumbi kunomthamo.
Ngokusekelwe kwiteknoloji yebhetri ye-lithium-ion yangoku, inqanaba loxinaniso lwamandla linokufezekiswa malunga ne-100 ~ 200Wh / kg, elisephantsi kwaye ibe yibhotile ye-lithium-ion izicelo zebhetri kwiimeko ezininzi. Le ngxaki iphinda ivele kwintsimi yezithuthi zombane, kumthamo kunye nobunzima buxhomekeke kwimida engqongqo, ubuninzi bamandla ebhetri bumisela ubuninzi bokuqhuba izithuthi zombane, ngoko "ixhala le-mileage" eli gama likhethekileyo. Ukuba uluhlu lokuqhuba lwesithuthi sombane olunye kufuneka lufike kuma-500 eekhilomitha (xa luthelekiswa nelo lwesithuthi esiqhelekileyo samafutha), ubuninzi bamandla ebhetri yemonoma kufuneka bube yi-300Wh/kg okanye ngaphezulu.
Ukwanda koxinano lwamandla ebhetri ye-lithium-ion yinkqubo ecothayo, ephantsi kakhulu kunoMthetho kaMoore kushishino lwesekethe edibeneyo, eyenza umahluko phakathi kokuphuculwa kokusebenza kweemveliso ze-elektroniki kunye nokuphuculwa koxinzelelo lwamandla eebhetri eziqhubeka zikhula ngokuhamba kwexesha. .
