Ndai hka hkin gau a matu lata la ai chemistry hpe Lithium (Li) Ferro/Iron (Fe) Phosphate (PO4), LiFePO4 (sh) LFP hpe kadun dawk tsun dan ai. Ndai chemistry hta LiFeMnPO4 & LiFeYPO4 zawn re ai n bung ai lam nkau mi nga ai raitim, jahtum e byin pru wa ai lam gaw, madung hku nna LFP bank langai mi naw rai nga ai, dai bank gaw, shingra tara hku nna shim lum ai atsam ningja ni nga ai. Ndai build a matu ngai gaw 400Ah Winston LFP prismatic cell mali hpe lata la nna, bank hpe 4S (sh) 4 series cell ni hpe gram lajang ai hta hpaw da ai.
4S gaw hpa rai ta?
4S gaw 12V nominal pack galaw na matu 3.2V cell mali ngu ai lachyum re. 13.3V pack langai mi gaw 13.2V – 13.35V grup yin rai nga ai majaw, pack/bannk gaw 13.3V pack hte teng sha grau ni htep ai.
4S configuration hta lai nna kaga galaw mayu ai rai yang cell ni hpe parallel shawng hta matut mahkai nna, series hku nna matut mahkai da ai. Parallel hpe shawng galaw ai majaw 12V nominal pack a matu cell voltage 4 hpe sha yu ra ai. Parallel cells ni gaw shingra tara hku nna rap ra ai ngu ai lachyum gaw manu n law ai BMS hpe law law lang lang mai ai. Series-first hpe lata na rai yang cell level hpe grau nna yu reng ra na re. 12V nominal house bank a matu law malawng mu lu na amying shingteng masa gaw lawu na hte maren rai nga ai;
4S=Series Cell mali
2P4S=Parallel Cell lahkawng / Series a Cell mali
3P4S=Parallel Cell masum/ Series mali
4P4S=Parallel cell mali/ Mali Series Cell mali
etc...
LiFePO4 Cell ni hpe series hku (sh) parallel/series hku nna gram lajang na matu ladat law law nga ai. Mai byin ai shaloi, ngai gaw 4S configuration a asan sha ai lam hpe grau ra sharawng ai, dai cell size gaw ra sharawng ai Ah atsam. 4S a matu bungli galaw ai rai yang, cell balancing galaw ai shaloi, yawng hkra matut mahkai lam n law ai hte bungli n law ai. Nkau mi gaw, cell langai hpe 2P4S bank hte jahten kau ai rai yang, dai hpe bai jep yu nna ngam ai cell ni hpe lang mai ai ngu tsun na re. Panglai kaw kun? Hpa mi rai rai mai byin ai raitim, ngai hku nna gaw, panglai hta hkum tsup ai LFP re{9}} hpe n-gun jaw ai hku nna, reserve langai a asan sha ai lam hpe grau ra sharawng ai. Lead acid reserve bank (sh) start/reserve gaw, byin mai ai manghkang ni hpe hparan ai shaloi, LFP bank hpe off{11}}line hpe raw kau na matu ahkang jaw ai. Panglai kaw LFP bank hpe bai gram lajang & rebalancing galaw ai gaw nang galaw mayu ai bungli n re.
