AI Customer ServiceA large number of studies show that the charge-discharge ratio of aging battery is significantly higher than that of normal capacity battery. When the charge-discharge current and cut-off voltage exceed a certain threshold, the capacity attenuation accelerates.
The attenuation of electrical power is mainly due to the change of the equivalent resistance of the battery, which is also caused by side reactions and the rupture of the electrode structure, And the common manifestation is the generation of a solid electrolyte interface (SEI) film on the electrode surface.
The charging and discharging capacity of batteries with high aging degree will change significantly under extreme conditions [ 83, 84 ]. However, the capacity attenuation of the battery during aging can be expressed by SOH, and the estimated correction of SOC must also depend on the SOH [ 85 ].
When the charge-discharge current and cut-off voltage exceed a certain threshold, the capacity attenuation accelerates. Therefore, stabilizing the battery capacity requires automatic control of the charging and discharging current and cut-off voltage of the aging batteries [ 71 ].
Additional macroscopic influences, such as Mean cycle SoC, Calendar SoC, and user behavior, are among the important factors that affect battery aging. When the battery is cyclically charged and discharged, each cycle will have a certain impact on the battery life, and this impact is gradually accumulated as the number of cycles increases.
Common SOH prediction methods. Under unrelated conditions (offline), measuring the aging parameters (capacity, internal resistance, etc.) of lithium-ion batteries to obtain the characteristic parameter values of the battery at this time, and finally using the SOH definition to evaluate the current degree of battery attenuation.
