Does pulse charging improve lithium-ion battery performance?

The application of pulse charging in lithium-ion batteries is relatively complex, and only a few studies suggest that pulse charging may lead to battery degradation . However, the majority of the current research still shows that pulse charging has a positive impact on improving the performance of lithium-ion batteries [, , ].

Do pulse charging parameters affect the performance of a LiPo battery?

However, there has not been much work to delve into which of the pulse charging parameters affect the performance metrics of the LiPo battery. This paper presented a summarization of the impact of the pulse charging parameters, i.e., duty cycle and frequency, on the charging time, cycle life, and the charge and energy efficiencies of the battery.

Does pulse charge duty cycle affect lithium-ion polymer battery performance?

Investigations of the combined impact of pulse charge duty cycle and frequency of the pulse charge current on the performance of lithium-ion polymer (LiPo) batteries used the Taguchi orthogonal arrays (OA) to identify optimal and robust pulse charging parameters that maximize battery charge and energy efficiencies while decreasing charge time.

How does pulse charging affect battery performance?

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.

Does pulse charging extend the life cycle of Li-ion batteries?

Other works, References [ 12, 13] have investigated the impact of pulse charging on the life cycle of Li-ion batteries and found that pulse charging extended the life of Li-ion batteries when compared with dc charging protocols.

Do pulse charging algorithms affect the cycle life of batteries?

The impact of the proposed pulse charging algorithms on the cycle life of batteries are not evaluated in most previous works. It is important to evaluate the benefits of proposed pulse charging algorithms across both charge time and cycle life to prevent frequent replacement of batteries, which is something this work evaluates.
