State of Health (SOH) chhiar dan tur .
Battery soh pawh a dam chhung atan a sawi theih bawk. Battery lifespan hi hman dan hrang hrang atanga thlirin chi hnih ah then theih a ni a, chungte chu storage lifespan leh cycle lifespan te an ni.
Storage Lifespan hian aging phenomena leh storage laiin battery result a entir a ni. Storage lai hian battery capacity chu a tlahniam thei lo va, self-discharge rate chu storage environment a zirin a danglam nasa hle. Chuvangin, battery aging rate acceleration emaw deceleration emaw chu storage environment ah a innghat a ni. Storage temperature hi storage lifespan leh self-discharge te nghawngtu lian ber a ni. Room temperature nena khaikhin chuan battery dahkhawlna temperature sang zawk chuan side reaction (corrosion ang chi) a siam tam zawk a, metal cations hloh pawh a na zawk a Temperature hniam takah chuan substance leh electrochemical reaction diffusion a tlahniam a, chu chuan battery aging rate a tihhniam phah a ni. Battery dahkhawmna nunna tichhe thei thil dang chu battery dahkhawm laiin SOC value a ni (hetah hian SOC hi electrode-a ion ratio tihna a ni). Storage temperature inang mahse battery storage soCs danglam takah chuan battery aging path a danglam. SOC sang takah chuan electrode/electrolyte interface-ah charge imbalance lian tak a awm a, hei hian electrochemical reaction a tichak a ni.
Cycle life hian battery hmanna (charging leh discharging) in battery a nghawng dan a entir a ni. Battery tarna hi charging leh discharging lai pawhin a thleng chhunzawm zel a ni. Battery hman chhunga temperature leh current hian cycle life a nghawng nghal vek a ni. Chu bakah, battery dahkhawlna nun tichhe thei thilte pawhin cycle life a nghawng a, a chhan chu battery hman lai emaw, chawlh lai emaw pawh nise, a kaihhnawih reaction a awm thin avangin. Battery hman hi exothermic process a ni a; Temperature sang hian heng reaction te hi a ti chak a, chu chuan battery tar chakna a ti chak zawk a ni. Heng variable te bakah hian cycle life nena inzawm parameters te hi battery state of charge function te an ni. Discharge pakhata charge hloh zat (change in state of charge) hi thil pawimawh tak a ni a, battery tar chaknaah nghawng lian tak a nei a ni. He thil thleng hi a chhan ber chu positive electrode a chhiat vang leh SEI film siam mek a nih lai hian high-tuna charging leh discharging a awm vang a ni.
1. Battery-a state of harm (SOH) tih awmzia sawifiahna .
SOH tih awmzia hrang hrang hi thlirna hrang hrang atanga lak chhuah theih a ni. Tunah hian battery research-a definition hman tlanglawn tak takte chu internal resistance definition, depth of discharge definition, leh a bak charge definition te a ni.
(1) In chhunga dodalna hrilhfiahna hmanrua .
Battery hian a chhungril lama a dona a san chhoh zel avangin hriselna dinhmun a chhe chho zel a ni. He inzawmna hmang hian Battery’s State of Health (SOH) hi a awmzia sawifiah theih a ni:
Formula-ah chuan RNEW hian battery siam chhuah laiin battery chhunga a resistance a entir a; Reol hian battery dam chhung tawp lama internal resistance a entir a; leh R hian battery chhunga a chhunga resistance awm mek chu a awm mek lai a entir a ni.
He hrilhfiahna atana pawimawh ber chu battery chhunga resistance atana value dik tak hmuh hi a ni. A thatna chu tehna result dik tak a ni a, mahse a chhiatna chu battery-a rated capacity, battery-a state of health (SOH) avanga nasa taka nghawng a ngaihtuah loh vang a ni.
(2) Depth of discharge (SOH) tih awmzia sawifiahna .
Battery pakhat depth of discharge (SOH) tih hian battery-in a capacity a discharge theihna ratio chu a capacity-ah a kawk a ni. He ratio hi battery recharge theih zat nen inversely proportional a ni a; Chu chu, discharge depth a tam poh leh a recharge theih zat a tlem zawk tihna a ni. Chuvangin, SOH hi discharge thuk zawng thlirna atanga sawifiah theih a ni: recharge la awm zat percentage chu discharge depth pek a recharge tam ber thlengin.
(3) Capacity la awm tih awmzia sawifiahna .

Chuvangin, Cnew chu hman loh hunah battery-a capacity sang ber ni rawh se, Cnorm chu battery hman theih zat sang ber ni rawh se. Tichuan, SOH chu...
