How to analyze battery capacity degradation process?

To analyze the capacity degradation process, batteries need to be cycled in various working conditions, in which a CC discharging process or a CC charging process is conducted to obtain battery discharging or charging capacity in each cycle. Fig. 2 (a) shows a typical cycling condition for battery cells tested in laboratory.

What is an EV battery aging experiment?

For example, Barré et al. establish an EV battery aging experiment, in which a check-up test is applied after a period of driving to calculate the capacity. This check-up test requires a full charging process with a low current, and the batteries are rested for an hour before and after the process.

How to reduce the degradation of a car battery?

With all these analyses above, it is clear that frequent and short charging rather than rare and prolonged charging, keeping the vehicle operating in a middle-low SOC, charging the battery when the SOC drops to less than 40 % but higher than 30 %, and avoiding the SOC dropping to less than 10 % can decrease the degradation.

How does battery fading affect EV performance?

The battery fading brings two distinct phenomena: the increase in internal resistance (Rint) and the decrease in capacity. For EVs, the capacity decline directly reduces the driving range; while the resistance increase can not only decrease the system efficiency but also reduce the system power capability.

Does charging a battery with a 30 % SoC reduce capacity degradation?

Moreover, correlations between capacity degradation and user behaviors are analyzed, and the results indicate that charging the battery with the start point at a SOC between 30 % and 40 % can effectively relieve the degradation. 1. Introduction
