More time and a higher magnitude of negative pulse resulted in a slow charging speed because the battery discharged during the negative pulse period; A higher current rate of the negative pulse could lead to a temperature rising and subsequently to a reduction of the battery life. Moreover, the charging capacity would be affected significantly;
In particular, the addition of negative pulse has a more obvious effect on improving the battery charging speed and slowing down the battery polarization.
Firstly, using the C–R pulse mode, it was determined that pulse charging has a positive impact on shortening the charging time for both LFP batteries and NMC batteries, and a smaller frequency is the key to improving battery performance and shortening the total charging time. For the C–R mode, the pulse current amplitude has the greatest impact.
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 .
The increase of the negative pulse time leads to a very long charging time because the battery not only stops charging but it is also discharged by the negative pulsed current. In Table 5, the temperature is not impacted by the changes in negative pulse time.
The C-D pulse charging mode extends battery cycle life. Pulse charging helps reducing concentration polarization in batteries. This study aims to experimentally investigate the impact of different pulse charging patterns on the charging time and performance of lithium-ion batteries at room temperature.
