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.
A pulsed current charging technique was previously proposed to improve the cycle life of lead-acid batteries [25, 26, 27, 28]. Then, it was extended to the Li-ion battery technique [6, 29, 30]. The current pulse and voltage pulse are the two types of pulse modes.
However, to get the benefits of pulse charging, the pulse charge current parameters have to be chosen carefully to ensure optimal battery performance and also extend the life cycle of the battery. The impact of pulse charge current factors on the life cycle and battery characteristics are seldom investigated.
Generally, the pulsed current is implemented by charging the battery cell using a charging protocol defined in advance, while the voltage pulse mode is implemented by controlling the duty cycle or frequency of the switching device to achieve the required average current. L. R.
The magnitude of pulsed current had the largest impact on the overall characteristics of batteries. A high magnitude current could shorten the charging time, while the charging capacity had a decrease and the battery temperature rose quickly. For the NPC strategy, the negative pulse time mainly impacted the charging speed.
Results from the accelerated aging of the battery indicated that pulse charging at method CC-CV. In terms of determining which factor and factor levels of the pulse charge current affected the cycle life of the batteries, the T aguchi OA approach was used. It was deduced that the by frequency at which the battery is charged.
