Kodi mphamvu yapamwamba ndi chiyani?
Mphamvu yapamwamba
SOP (State of Power) imatanthawuza kuchuluka kwamphamvu kwa batire pa paketi, yomwe ndi mphamvu yayikulu kwambiri yomwe batire ingatulutse kapena kuyamwa mkati mwa nthawi yodziwikiratu. Mphamvu yapamwamba imatha kugwiritsidwa ntchito kuwunika malire a kulipiritsa ndi kutulutsa kwa batire yamagetsi pansi pazigawo zosiyanasiyana zolipirira, kuchita gawo lofunikira pakuwongolera kufananiza pakati pa batire yamphamvu ndi mphamvu yagalimoto, komanso kukulitsa ntchito yobwezeretsanso mabuleki agalimoto yamagetsi. Ilinso ndi phindu lazambiri komanso lothandiza pakugwiritsa ntchito mabatire moyenera, kupewa kuchulutsa kapena kupitilira-kuthamangitsa, kuwongolera chitetezo cha batri, komanso kufutukula moyo wa batri. Komabe, mphamvu yapamwamba ya batri imakhala ndi malire ambiri otetezeka; mphamvu yokhayo yomwe ili m'malire achitetezowa ili ndi tanthauzo lenileni. Gawoli likukambirana za batire zomwe zimachepetsa mphamvu ya batri ndikuwunika ubale womwe ulipo pakati pa chitetezo cha batri ndi mphamvu yayikulu.
Kutentha-kutengera zopinga
Ma conductivity a electrolyte ndi ntchito ya anode ndi cathode zipangizo amasintha ndi kutentha, motero zimakhudza malire chapamwamba cha batire mlandu ndi kutulutsa mphamvu. Mlingo wa ma elekitirodi amachepetsa pamene kutentha kumachepa. Kutentha kumakhudzanso kuchuluka kwa ma ion ndi ma electron mu electrolyte. Mitengoyi imawonjezeka ndi kutentha kwakukulu komanso mosiyana. Komanso, ngati kutentha kuli kwakukulu kwambiri, kupitirira malire a kutentha kwapadera, mlingo wa mankhwala mkati mwa batri udzasokonezeka, zomwe zimapangitsa kuti pakhale chitetezo cha batri.
Monga momwe zasonyezedwera pa Chithunzi 8-31, mphamvu yaikulu ya batire imasintha ndi kutentha, kusonyeza mokhotakhota momveka bwino. Mphamvu yapamwamba imachepa pamene kutentha kumachepa, kusintha pang'onopang'ono pa kutentha kochepa. Ngakhale mphamvu yapamwamba imawonjezeka ndi kutentha kwakukulu, kutentha kwambiri kumapangitsa kuti kutentha kukhale kovuta, kusokoneza chitetezo cha batri ndi moyo wautali.
SOC-zolephereka
The State of Charge (SOC) constraint on State of Operation (SOP) yapangidwa kuti iteteze kuchulutsa komanso kupitirira-kutha kwa batire panthawi yogwira ntchito, kuonetsetsa kuti batire ili yotetezeka. Pophunzira za ubale pakati pa mphamvu zapamwamba ndi SOC, chikoka cha zinthu monga kutentha ndi mtengo / kutulutsa mlingo pa SOC ziyeneranso kuganiziridwa kuti ziwongolere kulondola kwa kuyeza kwa SOC. Monga momwe tawonetsera pa Chithunzi 8-32, pamene SOC ikuwonjezeka, mphamvu zotulutsa zimawonjezeka pamene mphamvu yowonjezera imachepa. Mwachitsanzo, mkati mwa mtundu womwewo wa SOC, pamene SOC ikukwera kuchokera ku 10% mpaka 90%, mphamvu yotulutsa nsonga imawonjezeka kuchokera ku 222W kufika ku 693W, pamene mphamvu yowonjezera imatsika kuchokera ku 675W kufika ku 300W. Kuwerenga mphamvu yapamwamba pansi pamikhalidwe yosiyanasiyana ya SOC kumatha kuyerekeza kuchuluka kwa batire / kutulutsa kwamagetsi, kupereka deta ndi chithandizo chaukadaulo pakugwiritsa ntchito kwake pamagalimoto amagetsi.
Zoletsa zochokera ku ohmic kukana
Monga momwe tawonetsera pa Chithunzi 8-33, mphamvu yapamwamba ya batri imakhala yofanana mosiyana ndi kukana kwake kwa mkati mwa ohmic. Zing'onozing'ono za kukana kwa mkati mwa ohmic, mphamvu yaikulu komanso yothamanga kwambiri; kukula kwa ohmic mkati kukaniza, kucheperachepera ndi pang'onopang'ono mphamvu yapamwamba.
Kutentha kwa batri, state of charge (SOC), ndi kukana kwamkati zonse zimagwirizana kwambiri ndi chitetezo chake. Chifukwa chake, momwe batire imagwirira ntchito (SOP) iyenera kukwaniritsa zopinga zomwe zimayikidwa ndi zinthu zitatuzi kuti zitsimikizire kuti zikugwira ntchito motetezeka ndikutalikitsa moyo wake.
