Hence pulse charging can prolong the life of lithium-ion batteries [31, 32]. The battery can be preheated using pulse charging only when the capacity of the battery is more than 50% since the pulsed heating method involves pulse discharging, which consumes the capacity of battery .
Pulse charging refers to the use of periodically changing current to charge the battery. The pulse current can be positive (i.e. charging) or negative (i.e. discharging). Because the period of pulse charging can be very short, relatively high currents can be used . Pulse charging of a lithium-ion battery has several advantages.
In this work, the impact of pulse charging protocols with various pulse parameters on the performance of lithium-ion batteries at low temperature is studied. This work designed and conducted two groups of experiments on pulse charging methods to preheat the battery at low temperature.
A preliminary evaluation of an all-solid-state, polymer electrolyte-based, rechargeable lithium battery technology has been undertaken, in terms of its performance under pulsed-discharge conditions.
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 .
The model results show that pulse charging enhances uniformity of lithium-ion distribution in the battery, thereby improving the battery performance. This research demonstrates pulse charging is a viable option to improve battery charging performance at low temperatures compared to the CC-CV charging method. 1. Introduction
