1. Mphamvu (gawo: Ah)
Ichi ndi parameter yomwe aliyense amakhudzidwa nayo kwambiri. Kuchuluka kwa batri ndi chimodzi mwa zizindikiro zofunika kwambiri zoyezera momwe batire ikuyendera, zomwe zimasonyeza kuti pansi pazifukwa zina (kuthamanga, kutentha, kuthetsa magetsi, ndi zina zotero) batire imatulutsa kuchuluka kwa magetsi (mayeso a JS-150D omwe alipo) , ndiko kuti, mphamvu ya batri, kawirikawiri mu amperage - maola ngati unit (chidule, chofotokozedwa mu AH, 1A-h = 3600C). Mwachitsanzo, ngati batire ndi 48V200ah, zikutanthauza kuti batire akhoza kusunga 48V*200ah=9.6KWh, mwachitsanzo, 9.6 kilowatts magetsi. Kuchuluka kwa batri kumagawidwa kukhala mphamvu zenizeni, mphamvu zongoyerekeza ndi mphamvu zovoteledwa molingana ndi mikhalidwe yosiyanasiyana.
Mphamvu zenizeniamatanthauza kuchuluka kwa magetsi omwe batire lingapereke pansi pa nthawi inayake yotulutsa (mulingo wina wa sedimentation, kachulukidwe kena kake kakali pano ndi mphamvu inayake yothetsa). Kuthekera kwenikweni sikuli kofanana ndi mphamvu yovotera, yomwe imagwirizana mwachindunji ndi kutentha, chinyezi, kulipiritsa ndi kutulutsa. Nthawi zambiri, mphamvu zenizeni zimakhala zocheperako kuposa zomwe zidavotera, nthawi zina zimakhala zocheperako kuposa zomwe zidavoteredwa.
Kuthekera kwamalingalirokutanthauza kuchuluka kwa magetsi operekedwa ndi zinthu zonse zomwe zimagwira ntchito pa batri. Ndiko kuti, mphamvu m'malo abwino kwambiri.
Mphamvu zovoteledwaimatanthawuza dzina la dzina lomwe likuwonetsedwa pagalimoto kapena zida zamagetsi zomwe zidavoteredwa zitha kupitiliza kugwira ntchito kwa nthawi yayitali. Nthawi zambiri amatanthawuza mphamvu zowoneka bwino za ma transfoma, mphamvu zogwira ntchito zama injini, ndi mphamvu zowonekera kapena zokhazikika pazida zowongolera magawo, mu VA, kVA, MVA. Pogwiritsira ntchito, geometry ya pole plate, termination voltage, kutentha, ndi kutulutsa mphamvu zonse zimakhudza mphamvu ya batri. Mwachitsanzo, m'nyengo yozizira kumpoto, ngati foni yam'manja ikugwiritsidwa ntchito panja, mphamvu ya batri idzatsika mofulumira.
2. Kuchuluka kwa Mphamvu (gawo: Wh/kg kapena Wh/L)
Kachulukidwe ka mphamvu, kachulukidwe ka batire, pa chipangizo chosungiramo mphamvu ya electrochemical, chiŵerengero cha mphamvu chomwe chingathe kulipiritsidwa ku unyinji kapena kuchuluka kwa malo osungira. Yoyamba imatchedwa "mass energy density", yomalizayo imatchedwa "volumetric energy density", unit ndi motsatira watt-hour/kg Wh/kg, watt-hour/lita Wh/L. Mphamvu apa, ndi mphamvu zomwe tatchulazi (Ah) ndi magetsi ogwiritsira ntchito (V) ophatikizika. Zikafika pamapulogalamu, metric of energy density ndi yophunzitsa kuposa mphamvu.
Kutengera luso la batri la lithiamu-ion lomwe lilipo, mphamvu ya kachulukidwe kamphamvu imatha kupezeka pafupifupi 100 ~ 200Wh/kg, yomwe idakali yotsika kwambiri ndipo yakhala cholepheretsa kugwiritsa ntchito batri ya lithiamu-ion nthawi zambiri. Vutoli limapezekanso m'munda wa magalimoto amagetsi, mu voliyumu ndi kulemera kwake zimakhala ndi malire okhwima, kachulukidwe ka mphamvu ka batire kumatsimikizira kuchuluka kwa magalimoto amagetsi, kotero "nkhawa yamakilomita" ili ndi mawu apadera. Ngati galimoto yamagetsi yoyendetsa galimoto imodzi iyenera kufika makilomita 500 (kuyerekeza ndi galimoto wamba yamafuta), mphamvu ya batire imodzi iyenera kukhala 300Wh/kg kapena kupitirira apo.
Kuwonjezeka mphamvu kachulukidwe wa mabatire lifiyamu-ion ndi ndondomeko pang'onopang'ono, m'munsi kwambiri kuposa Chilamulo Moore mu Integrated dera makampani, amene amalenga kusiyana pakati pa ntchito kusintha kwa zinthu zamagetsi ndi mphamvu kachulukidwe kusintha kwa mabatire amene akupitiriza kufutukuka pakapita nthawi. .
