A 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 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 ].
External factors are also important reasons for the intensification of internal aging. Internal aging of the battery eventually causes varying degrees of internal resistance increase, loss of active lithium ions and loss of active materials. The mechanism of various influencing factors on battery aging is shown in Fig. 6.
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 ].
The aging effects that may occur during battery storage, such as self-discharge, impedance rise, mechanical degradation and lithium precipitation, will affect the service life of the batteries. The aging problem in the storage process can be controlled through capacity loss, impedance rise, potential change, state of charge and state of health.
Capacity degradation refers to the continuous reduction in the battery maximum available discharge capacity during its use in specific scenarios. This has a significant impact on both the decrease in EV driving range and reduced EES capacity throughput.
