O lo tatou Fa'amanuiaga
O le a le SoH (State-of-Health) mo se maa?
State-of-health (SoH) ma le State-of-Charge (SoC) o faʻailoga autu taua aua latou te tuʻuina atu faʻamatalaga aoga tele e manaʻomia mo le faʻaleleia atili o le Faʻatonuga o le Pulea o le Maʻa (BMS).
State-of-charge ma state-of-health o ni taʻiala eseese e mafai ona fenumiai i nisi taimi. O le fa'amoemoe o lenei tusiga o le fa'amalamalama manino lea o fa'amatalaga ta'itasi ma fa'amatala lona taua ma lona fa'aoga.
Le tulaga-o-soifua maloloina (SoH o le maa o loʻo faʻamatalaina le eseesega i le va o se maa o loʻo suʻesuʻeina ma se maa fou ma mafaufau i le matua o le cell.
E faauigaina o le fua faatatau o le maualuga o le tau o le maa i lona tulaga gafatia. O lo'o fa'aalia o se pasene e pei ona va'aia i lalo.
Qmax/mAh = Le maualuga o le tau e maua o le maa
Cr = Le gafatia fa'atatau
Ata 2: Evolution ole SoH ole maa ile matua
E a'afia le tulaga o le soifua maloloina ole ma'a lua ole fa'ama'i. O le maualalo o le SoHSoH, o le vave foi lea o le faʻamalo o le maa e pei ona faʻaalia i le Ata 3 o loʻo i lalo.
Ata 3: U vs. t i le taimi e fa'aalu ai le maa ma ta'amilosaga fa'aalu mo SoH eseese
E fa'afefea ona fuaina le SoC ma/po'o le SoH fa'atasi ai ma se BioLogic potentiostat / galvanostat po'o le uila uila
E mafai ona maua le tau o le SoC e ala i le mataituina o le tau o le maa (fuaina o le taimi nei ma le taimi). I lea itu, Galvanostatic Cycling with Potential Limitation (GCPL) technique fa'apea Chronopotentiometry (CP) ma Constant Current (CC) techniques e talafeagai.
O se tasi o auala o loʻo avanoa mo le fuafuaina o le SoH o le iloa lea o le aofaʻi o le tau Q e mafai ona teuina i se tulaga faʻapitoa. O le mea lea, o le EC-Lab® poʻo le BT-Lab® Battery Capacity Determination (BCD) e mafai ona faʻaogaina i lenei faʻamoemoe.
