6 FAQs about [Battery pulse discharge process]
What is pulse charge & discharge principle?
A. Pulse charge/discharge principle The concept of pulse charging is based on successive changes in current rate and/or direction rather than using a constant charging current. Basically, the current can either be interrupted, introducing a shorter rest period, or replaced by a Impact of periodic current pulses on Li-ion battery performance
Does pulse discharge affect battery performance?
In addition, other works showed that pulse discharge was detrimental to battery performance mainly due to the fact that the peak currents cause transients on the cell’s voltage that may be interpreted by the voltage cut-off circuit as an end-of-charge/discharge voltage .
Can a pulse discharge test a battery?
One recently introduced method 45 uses an acoustic wave passing through a battery to evaluate structure and SOC. In contrast, the results of this work demonstrate that a pulse discharge method can effectively match the ending SOC and isolate individual overvoltages within a battery.
