Kodi mudawonapo kuti mphamvu ya batri ya lithiamu imatsika itangoyimitsidwa kwathunthu? Ichi si chilema - ndi chikhalidwe chachibadwa chomwe chimadziwika kutikutsika kwamagetsi. Tiyeni titenge chitsanzo chathu cha 8-cell LiFePO₄ (lithium iron phosphate) 24V yachitsanzo cha batire yagalimoto yamagalimoto monga chitsanzo kuti tifotokoze.
1. Kodi Voltage Drop N'chiyani?
Mwachidziwitso, batire iyi iyenera kufika 29.2V ikakhala yokwanira (3.65V × 8). Komabe, mutachotsa gwero lamphamvu lakunja, voteji imatsika mofulumira mpaka 27.2V (pafupifupi 3.4V pa selo). Ichi ndichifukwa chake:
- The pazipita voteji pa kulipiritsa amatchedwa theCharge Cutoff Voltage;
- Kuyimitsa kukayimitsa, polarization yamkati imasowa, ndipo mphamvu yamagetsi imatsika mpakaTsegulani Circuit Voltage;
- Maselo a LiFePO₄ nthawi zambiri amalipira mpaka 3.5-3.6V, koma iwosangasunge mulingo uwukwa nthawi yayitali. M'malo mwake, iwo amakhazikika pa voteji nsanja pakati3.2V ndi 3.4V.
Ichi ndichifukwa chake magetsi akuwoneka ngati "akutsika" atangotha kulipira.
2. Kodi Kutsika kwa Voltage Kumakhudza Mphamvu?
Ogwiritsa ntchito ena akuda nkhawa kuti kutsika kwamagetsi kumeneku kumachepetsa mphamvu ya batri yomwe ingagwiritsidwe ntchito. Pamenepo:
- Mabatire a Smart lithiamu ali ndi machitidwe owongolera omwe amayezera molondola ndikusintha mphamvu;
- Mapulogalamu omwe ali ndi Bluetooth amalola ogwiritsa ntchito kuyang'aniramphamvu zosungidwa zenizeni(ie, mphamvu zotulutsa zomwe zingagwiritsidwe ntchito), ndikukonzanso SOC (State of Charge) pambuyo pa mtengo uliwonse;
- Chifukwa chake,Kutsika kwamagetsi sikupangitsa kuchepa kwa mphamvu yogwiritsira ntchito.
3. Nthawi Yoyenera Kusamala Pakugwa kwa Voltage
Ngakhale kutsika kwamagetsi kuli kwachilendo, kumatha kukokomeza pazinthu zina:
- Kutentha Impact: Kulipiritsa pa kutentha kwambiri kapena makamaka kutsika kungayambitse kuchepa kwa magetsi;
- Kukalamba Kwa Maselo: Kuchulukirachulukira kwamkati kapena kutsika kwamadzimadzi kungayambitsenso kutsika kwamagetsi mwachangu;
- Chifukwa chake ogwiritsa ntchito ayenera kutsata njira zogwiritsiridwa ntchito moyenera ndikuwunika thanzi la batri pafupipafupi.
Mapeto
Kutsika kwamagetsi ndizochitika zachilendo m'mabatire a lithiamu, makamaka mumitundu ya LiFePO₄. Ndi kasamalidwe ka batri kapamwamba komanso zida zowunikira mwanzeru, titha kutsimikizira zonse zolondola pakuwerengera mphamvu komanso thanzi lanthawi yayitali komanso chitetezo cha batri.
