Andrew adalongosola chifukwa chake khalidwe liyenera kusankhidwa poika mabatire a lithiamu-ion, ndi mabatire abwino kwambiri a lithiamu iron phosphate pamsika omwe tidasankha.
Mabatire a lithiamu ndi opepuka kwambiri kuposa lead-acid ndipo mwachidziwitso amakhala ndi kuchuluka kwa asidi wa lead kuwirikiza kawiri.
Chinsinsi cha kukhazikitsidwa bwino kwa mabatire a lithiamu-ion, kwa iwo omwe akufuna kutengera luso lamakono la batri kapena ngakhale kudzipereka ku mabwato amagetsi, ndikugwiritsa ntchito makina apamwamba a lithiamu-ion batire (BMS) ndi zomwezo. khalidwe loyamba.
BMS yabwino kwambiri idzakhala yogwirizana ndi momwe makhazikitsidwira, pomwe BMS yoyipa kwambiri ingokhala chitetezo chovuta kuti zisawonongeke.
Ngati cholinga chanu ndi kukhala ndi chitetezo, chodalirika komanso chokhazikika chosungira mphamvu pa bolodi, musayese kusunga ndalama pa BMS.
Koma kuti zinthu ziipireipire, pazida za lithiamu-ion, pakapita nthawi, kugwiritsa ntchito zinthu zotsika mtengo, zopangidwa bwino sizidzangowononga ndalama zambiri, komanso kumayambitsa ngozi yaikulu yamoto pa bolodi.
Batire ya LiFePO4 imalengezedwa ngati batire yoyenera ya "plug-in" lead-acid popanda kufunikira kwa zida zowonjezera zowonjezera.
Akuti amagwirizana ndi ma charger onse a lead-acid ndi ma converter a DC-to-DC omwe ali pamsika.Ali ndi BMS yomangidwa yomwe imatha kuyang'anira ndikuwongolera ntchito zawo zolipiritsa ndi kutulutsa kuti zitsimikizire chitetezo chokwanira, kudalirika komanso moyo wautali.
LiFePO4 ndi 35% yopepuka kuposa mabatire ofanana a lead-acid ndi 40% yocheperako kukula kwake.Ili ndi mphamvu yotulutsa kwambiri (<1kW/120A), 1C mtengo wamtengo wapatali komanso imatha kupereka mpaka 2,750 mizunguliro pansi pa 90% DoD, kapena mpaka 5,000-50%.% DoD
kuzungulira.
Kampani yaku Dutch Victron imadziwika chifukwa chamagetsi ake apamwamba kwambiri, omwe amapereka mabatire a 60-300Ah "plug-in" LFP, oyenera kuyika 12.8 kapena 25.6V, akatulutsidwa ku 80% ya DoD kapena mpaka ma 5,000, amatha. kupereka 2,500 Only 50% pa kuzungulira.
Ma tag anzeru amatanthauza kuti atha kugwiritsa ntchito gawo lophatikizika la Bluetooth pakuwunika kwakutali, koma amafunikira Victron VE.Bus BMS yakunja.
Malire apano otulutsa ndi 100A pa 100Ah, ndipo kuchuluka kwa mabatire mofananira ndi 5.
Mabatire olowa m'malo a LFP awa ali ndi BMS yomangidwira ndi radiator yapadera yoziziritsira batire ikamachapira.
Batire ya IHT "plug-in" 100Ah LiFePo4 yochokera kumtundu wodziwika bwino wa LFP Battle Wobadwa ku United States imatha kuvomereza 1C kuyitanitsa ndi 100A kutulutsa pakali pano (200A pachimake mumasekondi atatu okha) popanda kuwonongeka.
Amaphatikizanso BMS yokhazikika yomwe imatha kuyang'anira ma voltage, kutentha, kuchuluka kwa batri, komanso chitetezo chozungulira.
Ukadaulo waumwini wa Firefly umaphatikizapo thovu lopangidwa ndi mpweya wokhala ndi ma cell masauzande ambiri otseguka omwe amagawa ma electrolyte a sulfuric acid kudera lalikulu kuti apititse patsogolo mphamvu ya chemistry ya lead-acid.
The "microbattery" mu mpweya thovu electrolyte dongosolo akhoza kukwaniritsa apamwamba kutulutsa panopa mlingo, kuonjezera kachulukidwe mphamvu ndi kukulitsa mkombero moyo (<3x).
Imalolezanso kuyitanitsa mwachangu poyerekeza ndi mabatire anthawi zonse a lead-acid, omwe ndi abwino kwambiri akamatchaja kuchokera pazigawo zocheperako monga solar kapena alternator.
Ziphaniphani zimalimbana kwambiri ndi sulfate ndipo zimatha kugwiritsidwa ntchito ndi ma charger amtundu wa lead-acid komanso zowongolera zina.
M'mabatire akuya-cycle absorption glass fiber mat (AGM), carbon cathode imati imawonjezera kuvomereza kwa mtengo, potero imafulumizitsa njira yolipiritsa, kuonjezera kuchuluka kwa mikombero yomwe ilipo komanso kuchepetsa kuwononga kwa mbale.
Batire yotsogolera ya kristalo ndi asidi osindikizidwa (SLA) omwe amagwiritsa ntchito electrolyte ya SiO2 acid yowonjezera, yosawononga yomwe idzawala pakapita nthawi, ndikupangitsa kuti ikhale yamphamvu komanso yogwira ntchito bwino.
Choyera choyera kwambiri cha calcium-selenium electrode mbale ndi electrolyte zimasungidwa mu microporous pad, kotero kuti kuthamanga kwa batire kuli kawiri kawiri kuposa SLA wamba, kutulutsa kumakhala kozama, kuzungulira kumakhala pafupipafupi, ndipo kumagwiritsidwa ntchito kwambiri. kutentha kwambiri kuposa mabatire a lithiamu-ion ndipo amapereka ntchito yabwino Ma AGM ena ambiri amakhala ndi moyo wautali wautumiki.
Kaputeni wodziwa bwino komanso akatswiri odziwa bwino za yacht pamwezi amalangiza oyendetsa panyanja pazinthu zingapo

Pogwiritsa ntchito ukadaulo waukhondowu womwe ulibe cadmium kapena antimony, batire yotsogolera ya kristalo imatha kubwezeredwa mpaka 99%, ndipo koposa zonse, imayikidwa ngati mayendedwe osakhala owopsa.
