Ndi kutchuka kwa malingaliro obiriwira oyenda ndi chitukuko chokhazikika, ngolo zamagetsi za gofu zakhala malo ofunikira othandizira masewera a gofu padziko lonse lapansi. Monga "mtima" wa galimoto yonse, batire imatsimikizira mwachindunji kupirira, ntchito ndi chitetezo. Kuchokera pa batire loyambirira la lead-acid mpaka batire yaposachedwa ya lithium iron phosphate (LiFePO4), kusinthika kwaukadaulo kwasintha kwambiri luso la kagwiritsidwe ntchito ka ngolo ya gofu. Nkhaniyi ifotokoza za ubwino wa LiFePO4 poyerekeza ndi mabatire otsogolera-asidi achikhalidwe ponena za chitetezo, moyo wozungulira, kachulukidwe ka mphamvu, kusinthasintha kwa kutentha ndi kuthamanga kwachangu.
Kuchepa kwa mabatire a lead-acid
Mabatire a lead-acid kale ankagwiritsidwa ntchito kwambiri m'ngolo za gofu chifukwa cha mtengo wake wotsika komanso umisiri wokhwima. Komabe, amakhalanso ndi mabotolo ambiri: ndi olemetsa ndipo amakhala ndi malo ambiri, zomwe zimapangitsa kuchepa kwa kayendetsedwe ka galimoto yonse; ali ndi zofunikira zosamalira kwambiri ndipo amafunika kuwonjezeredwa nthawi zonse ndi madzi osungunuka, apo ayi amakhala ndi sulfation ndikufupikitsa moyo wawo. Kuphatikiza apo, moyo wozungulira wa mabatire a lead-acid nthawi zambiri umakhala pafupifupi nthawi 300-500, ndipo kusinthidwa pafupipafupi kumawonjezera mtengo wogwiritsa ntchito nthawi yayitali.
Ubwino wa Mabatire a LiFePO4
Chitetezo
Mabatire a LiFePO4 ali ndi matenthedwe apamwamba kwambiri komanso kukhazikika kwamankhwala, samakonda kuthawa kapena kuyaka, ndipo ndi ochezeka komanso osakhala ndi poizoni. Pansi zinthu zachilendo monga kutentha kwambiri kapena dera lalifupi, chitetezo malire a LiFePO4 kutali kuposa ena lifiyamu kachitidwe batire, ndipo angapereke odalirika ntchito zitsimikizo kwa ngolo ngolo.
Moyo Wozungulira
Moyo wozungulira wa mabatire a LiFePO4 ndiwokwera kwambiri kuposa mabatire a lead-acid. Nthawi zambiri, ndi nthawi zopitilira 2,000, ndipo zinthu zapamwamba zimatha kufika nthawi 3,000-5,000, zomwe zikutanthauza kuti zitha kugwiritsidwa ntchito mosalekeza kwa zaka 5-10 pansi pa kutulutsa kozama kamodzi patsiku. Mosiyana ndi izi, mphamvu ya mabatire a acid-lead idzawola mpaka kuchepera 80% ya mphamvu yoyambirira pambuyo pa ma 500, zomwe zimafunikira kusinthidwa pafupipafupi, ndikuwonjezera kwambiri ndalama zosamalira komanso kutayika kwa nthawi yocheperako.
Kuchuluka kwa Mphamvu
Kuchuluka kwa mphamvu ndi chizindikiro chofunikira chaukadaulo wa batri. Pa mphamvu yomweyi, kulemera kwa batire LiFePO4 ndi za 1/3 chabe ya batire-asidi kutsogolera, ndi voliyumu ndi za 1/2, amene amachepetsa kwambiri galimoto kulemera ndi bwino kuyendetsa osiyanasiyana ndi galimoto katundu mphamvu. Kuonjezera apo, kuya kwapamwamba kwambiri (DoD ikhoza kufika 80-100%) kumapangitsa kuti mphamvu yogwiritsira ntchito mphamvu ikhale yokwera, pamene DoD yabwino kwambiri ya batri ya lead-acid ndi pafupifupi 50%, kuwononga mphamvu zambiri zomwe zingatheke.
Kutentha Kusinthasintha
M'malo otentha otsika, magwiridwe antchito a batire ya asidi-acid amatsika kwambiri, ndipo kutaya mphamvu kumatha kufika kupitirira 50%; pamene LiFePO4 batire akhoza kukhalabe oposa 80% ya mphamvu ndi linanena bungwe voteji pa -10 ° C, ndi osachepera kololeka ntchito kutentha angafikire -20 ° C, amene ali khola m'nyengo yozizira kapena ozizira m'mawa sitediyamu chilengedwe.
Kutha Kutsatsa Mwachangu
Batire ya LiFePO4 imathandizira kuthamanga kwapamwamba (mpaka 0.5C kapena 1C), yomwe imafupikitsa nthawi yodikirira yodikirira ndikuwongolera kuyendetsa bwino kwagalimoto. Mosiyana ndi izi, mtengo wovomerezeka wa mabatire a lead-acid ndi 0.1C-0.2C okha, ndipo nthawi zambiri zimatenga maola 6-8 kuti azilipiritsa, zomwe zimakhala zovuta kukwaniritsa zofunikira za ma opareshoni othamanga kwambiri.
Mtengo Wokwanira ndi Mtengo
Ngakhale kuti ndalama zoyamba za mabatire a LiFePO4 ndi 30-50% apamwamba kuposa mabatire a lead-acid, chifukwa cha moyo wake wabwino kwambiri komanso mawonekedwe otsika okonza, mtengo wake ukhoza kukhala wofanana kapena wotsika mkati mwa zaka 5. M'kupita kwanthawi, LiFePO4 imachepetsa nthawi zambiri zosinthira ndi kukonza maola, ndipo mtengo wonse wa umwini (TCO) wobweretsedwa ndi wopikisana kwambiri kuposa wa mabatire a lead-acid.
Mapeto
Kuchokera pachitetezo, moyo wozungulira, kachulukidwe kamphamvu, kusinthasintha kwa kutentha mpaka kuthamangitsa mwachangu, mabatire a LiFePO4 awonetsa zabwino zambiri pamakaseti a gofu. Ndi kukhathamiritsa kosalekeza kwa teknoloji ndi kupanga kwakukulu, mtengo wa mabatire a LiFePO4 udzapitirira kutsika. M'tsogolomu, akuyembekezeka kukhala gwero lamagetsi okhazikika pamangolo amagetsi a gofu komanso malo okulirapo a LSV (magalimoto otsika kwambiri), zomwe zimathandiza kuti masewera a gofu azikhala owoneka bwino, obiriwira komanso okhazikika.
