Popeza kuti magalimoto oyendera malo obiriwira ayamba kutchuka komanso malingaliro opititsa patsogolo chitukuko, magalimoto oyendera malo ochitira gofu amagetsi akhala malo ofunikira othandizira mabwalo a gofu padziko lonse lapansi. Monga "mtima" wa galimoto yonse, batireyo imatsimikiza mwachindunji kupirira, magwiridwe antchito, komanso chitetezo. Kuyambira batire yoyamba ya lead-acid mpaka batire ya lithium iron phosphate (LiFePO4) yomwe ilipo, kusintha kwaukadaulo kwasintha kwambiri momwe ngolo ya gofu imagwirira ntchito komanso momwe imagwirira ntchito bwino. Nkhaniyi ikuyang'ana kwambiri zabwino za LiFePO4 poyerekeza ndi mabatire achikhalidwe a lead-acid pankhani ya chitetezo, moyo wa kuzungulira, kuchuluka kwa mphamvu, kusinthasintha kwa kutentha komanso liwiro lochaja.
Zofooka za mabatire a lead-acid
Mabatire a lead-acid ankagwiritsidwa ntchito kwambiri m'magalimoto a gofu chifukwa cha mtengo wawo wotsika komanso ukadaulo wawo wokhwima. Komabe, ali ndi zovuta zambiri: ndi olemera ndipo amakhala ndi malo ambiri, zomwe zimapangitsa kuti galimoto yonse isamayende bwino; amafunika kukonza bwino ndipo amafunika kuwonjezeredwa madzi osungunuka nthawi zonse, apo ayi amatha kusungunuka ndi kufupikitsa moyo wawo. Kuphatikiza apo, nthawi yogwiritsira ntchito mabatire a lead-acid nthawi zambiri imakhala pafupifupi nthawi 300-500, ndipo kusintha pafupipafupi kumawonjezera mtengo wogwiritsidwa ntchito kwa nthawi yayitali.
Ubwino wa Mabatire a LiFePO4
Chitetezo
Mabatire a LiFePO4 ali ndi kukhazikika kwakukulu kwa kutentha ndi mankhwala, sachedwa kutenthedwa kapena kuyaka, ndipo ndi abwino kwa chilengedwe komanso osawononga chilengedwe. Pazifukwa zachilendo monga kutentha kwambiri kapena kufupika kwa magetsi, malire a chitetezo a LiFePO4 amaposa kwambiri a machitidwe ena a mabatire a lithiamu, ndipo amatha kupereka chitsimikizo chodalirika chogwiritsira ntchito magaleta a gofu.
Moyo wa Kuzungulira
Moyo wa mabatire a LiFePO4 ndi wokwera kwambiri kuposa wa mabatire a lead-acid. Nthawi zambiri, amakhala oposa 2,000, ndipo zinthu zapamwamba zimatha kufika 3,000-5,000, zomwe zikutanthauza kuti zitha kugwiritsidwa ntchito mosalekeza kwa zaka 5-10 ngati zitulutsidwa mozama kamodzi patsiku. Mosiyana ndi zimenezi, mphamvu ya mabatire a lead-acid imachepa kufika pa 80% ya mphamvu yoyambirira pambuyo pa maulendo 500, zomwe zimafuna kusinthidwa pafupipafupi, ndikuwonjezera kwambiri ndalama zokonzera ndi kutayika kwa nthawi yopuma.
Kuchuluka kwa Mphamvu
Kuchuluka kwa mphamvu ndi chizindikiro chofunikira cha ukadaulo wa batri. Pa mphamvu yomweyo, kulemera kwa batri ya LiFePO4 ndi pafupifupi 1/3 yokha ya batri ya lead-acid, ndipo voliyumu yake ndi pafupifupi 1/2, zomwe zimachepetsa kwambiri kulemera kwa galimotoyo ndikukweza kutalika kwa mayendedwe ndi mphamvu ya katundu wa galimotoyo. Kuphatikiza apo, kuzama kwakukulu kwa kutulutsa mphamvu (DoD kumatha kufika 80-100%) kumapangitsa kuti mphamvu yogwiritsira ntchito bwino ikhale yokwera, pomwe DoD yabwino kwambiri ya batri ya lead-acid ndi pafupifupi 50% yokha, kuwononga mphamvu zambiri zomwe zingatheke.
Kusinthasintha kwa Kutentha
Mu malo otentha pang'ono, magwiridwe antchito a batire ya lead-acid amatsika kwambiri, ndipo kutayika kwa mphamvu kumatha kufika pa 50%; pomwe batire ya LiFePO4 imatha kusunga mphamvu ndi mphamvu zotulutsa mphamvu zoposa 80% pa -10°C, ndipo kutentha kocheperako kovomerezeka kumatha kufika pa -20°C, komwe kumakhala kokhazikika kwambiri m'nyengo yozizira kapena m'mawa.
Kutha Kuchaja Mwachangu
Batire ya LiFePO4 imathandizira kuchuluka kwa chaji (mpaka 0.5C kapena ngakhale 1C), zomwe zimafupikitsa kwambiri nthawi yodikirira chaji ndikukweza magwiridwe antchito a galimoto. Mosiyana ndi zimenezi, kuchuluka kwa chaji komwe kumalimbikitsidwa kwa mabatire a lead-acid ndi 0.1C–0.2C yokha, ndipo nthawi zambiri zimatenga maola 6-8 kuti chaji igwire bwino ntchito, zomwe zimakhala zovuta kukwaniritsa zosowa za ntchito zama frequency apamwamba.
Mtengo ndi Mtengo Wonse
Ngakhale kuti ndalama zoyambira zomwe mabatire a LiFePO4 amaikamo ndi 30–50% kuposa mabatire a lead-acid, chifukwa cha moyo wake wabwino komanso kusakonza bwino, mtengo wake wonse ukhoza kusungidwa womwewo kapena wotsika mkati mwa zaka 5. Pakapita nthawi, LiFePO4 imachepetsa kuchuluka kwa maola osinthira ndi kukonza, ndipo mtengo wonse wa umwini (TCO) womwe umabweretsedwa ndi iyo ndi wopikisana kwambiri kuposa mabatire a lead-acid.
Mapeto
Kuyambira pa chitetezo, moyo wa njinga, kuchuluka kwa mphamvu, kusinthasintha kwa kutentha mpaka kutha kuyatsa mwachangu, mabatire a LiFePO4 awonetsa zabwino zambiri pakugwiritsa ntchito ngolo ya gofu. Ndi kukhathamiritsa kosalekeza kwa ukadaulo ndi kupanga kwakukulu, mtengo wa mabatire a LiFePO4 upitiliza kutsika. M'tsogolomu, akuyembekezeka kukhala gwero lamphamvu la ngolo yamagetsi ya gofu komanso ngakhale gawo lalikulu la LSV (galimoto yothamanga pang'ono), kuthandiza ntchito za bwalo la gofu kukhala zogwira mtima, zobiriwira komanso zokhazikika.
