Rapid development of electronic devices, ranging from personal communication devices to electric mobility solutions, has increased demand for energy storage devices
By dividing the measured current (in amps) by the battery''s capacity (in ampere-hours), you can calculate the C-rate. For example, if a 2,000mAh battery is charging at 1,000mA: C-rate = 1,000mA ÷ 2,000mAh = 0.5C. Part 4. How does the charging and discharging rate affect battery performance? The charging and discharging rates play a critical
In a typical single-phase battery energy storage system, the battery is subject to current ripple at twice the grid frequency. Adverse effects of such a ripple on the battery performance and lifetime would motivate modifications to the design of the converter interfacing the battery to the grid.

Similar to the previous paper, the authors confirmed that high currents had a greater effect on aging. Moreover, they also stated that high charging currents aged the battery more than the discharging ones. Also in this case, the battery temperature depends on the current rate and, therefore, the two effects are not separable with these tests.
