Pankhani ya funso loyamba: Ndi gawo lotani la batri lomwe limayikidwa kuti likhale labwino kwambiri kuti litalikitse moyo wa batri?
Izi zimafunsanso za zotsatira za SOC zosiyanasiyana (SOC = mphamvu yomwe ilipo / mphamvu ya dzina) yosungirako mabatire a lithiamu-ion pa mphamvu ya batri;Mfundo yoyamba kukhala yomveka bwino ndi yakuti ma SOCs osiyanasiyana amakhudza kuchepa kwa batri panthawi ya ukalamba wosungira.Zimakhudza, ndipo zotsatira zake zimakhala zosiyana malinga ndi zinthu zosiyanasiyana;chifukwa cha nkhani mtengo, aliyense lifiyamu-ion sapulaya ndi terminal wopanga adzakhala ndi zofunika zosiyanasiyana mankhwala osiyanasiyana;koma kwa mabatire a lithiamu-ion, ma SOC osiyanasiyana amakhala ndi zotsatira zosiyana pa batri.Lamulo lofunikira la zotsatira za ukalamba wosungirako likugwiritsidwabe ntchito, koma pangakhale kusiyana pakati pa zinthu zosiyanasiyana;
Chithunzi 1abc ndi chojambula chosungirako chosungirako mabatire a lithiamu-ion omwe ali ndi machitidwe atatu omwe panopa akugulitsidwa pa SOC zosiyanasiyana ndi kutentha, ndipo lamulo lofunika likhoza kuwonedwa Pamene SOC ikuwonjezeka, kutayika kwa ukalamba wosungirako kumawonjezeka, kutentha kwa yosungirako kumawonjezeka, ndipo kutayika kwa ukalamba wosungirako kumawonjezekanso, ndipo zotsatira za kutentha kwakukulu pa kutayika kwa ukalamba kwa mabatire a lithiamu-ion mwachiwonekere ndizokulirapo kuposa za SOC.
Chithunzi 2 pansipa chikuwonetsa kusungirako kukalamba kwamitundu yosiyanasiyana ya mabatire a lithiamu-ion pansi pamikhalidwe yosiyanasiyana mwachidule m'mabuku owunikira.Zitha kuwoneka kuti lamuloli ndi lofanana ndi lomwe likuwonetsedwa pa Chithunzi 1.
Mabatire a laputopu nthawi zambiri amakhala ndi machitidwe awiri a electrochemical: ternary (NCM) ndi lithiamu cobalt oxide (LCO).Kutalikitsa moyo wautumiki, ndikofunikira kwambiri kuti musamatenthedwe kwambiri.SOC siyenera kukhala yokwera kwambiri kapena yotsika kwambiri.Ponena za mabatire a lithiamu-ion Sitikulimbikitsidwa kusunga SOC otsika kwambiri, chifukwa mabatire a lithiamu-ion adzakhala ndi zochitika zodzipangira okha panthawi yosungira, ndipo chiopsezo cha batri chidzakhala chochepa kwambiri ngati SOC ndi yotsika kwambiri. kuyambitsa mavuto osiyanasiyana mu batire, choncho tikulimbikitsidwa 20-25 ℃, 40-60% SOC yosungirako.Mutha kukumbukira mosamala kuti pazinthu zogulidwa zomwe zili ndi mabatire a lithiamu-ion, mphamvu ya batri ya boot yoyamba imakhala pakati pa 40-80%.Ponena za funso lachiwiri, pamene bukhuli likugwirizanitsidwa ndi magetsi akunja, batiri silipereka mphamvu, choncho silingakhudze ntchito yake.
