SOH represents health status, and it can be estimated by formula (3), wherein CagedRepresent the electricity of aging
Pond inclusion quantity, CnRepresent the nominal capacity quoted in each SOC calculating.
Because CnIt is known, therefore the mission critical for calculating SOH is to find Caged.A kind of possible side
Method is that the maximum electricity (or SOC) that can be reached is tracked in the whole service life of battery.If with
Carry out afterwards it is fully charged several times after, the maximum charge level of battery is less than the aging capacity being previously calculated,
Then represent that aging capacity diminishes.Accordingly, CagedIt must be counted with SOH according to coulomb and OCV methods are true
Fixed capacity is adjusted.Fully charged state monitors when charging current is reduced to below specified threshold.
Another method for determining SOH is that tracking is charged and discharged the cycle, is provided with battery manufacturers
Cycle stability point takes its rated value.Generally, manufacturer ensures that charging under assigned temperature and depth/put
Electric cycle total amount, for example, 500 cycles in 27 degrees Celsius, 25% depth of discharge.By by all weeks
Phase is rated for above-mentioned quantity, and applies temperature and charged state correction factor, can support to track above-mentioned
CagedValue.
