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 charge-discharge ratio has great influence on capacity attenuation of lithium battery. With the increase of charge-discharge ratio, the decline rate of the battery becomes faster. Reasonable control of the charge-discharge rate is an important guarantee of the battery's cycle service life .
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 .
