Charging a 12 V lead–acid car battery A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, is a device that stores energy in an electric battery by running current through it.

Pulse charging, which charges the battery by controlling the charging current, improves fast charging time and battery charging efficiency without significantly increasing costs [13,14,15]. However, to achieve the pulse charging effect, the duty and frequency of the pulse current must be appropriately selected [ 14 ].
Besides, given the relationship between the current frequency and the heat generated by the battery, a low frequency (0.01–0.1 Hz) was chosen to achieve higher heat production. Second, the pulse self-heating of the battery was carried out alternately by employing the VACV charge heating mode and the VACV discharge heating mode.
However, if the pulse charging frequency is too high or the voltage exceeds safe limits, it can lead to overheating or stress on the battery''s internal structure. The evidence regarding the impact of pulse charging on battery life is mixed. Some studies suggest pulse charging can enhance battery lifespan by reducing heat build-up, while

A pulse charger is a type of battery charger that uses pulses of current to charge batteries. Unlike traditional chargers that supply a constant current, pulse chargers deliver short bursts of high current followed by periods of no current.
The mechanism behind pulse charging involves generating high-frequency charge pulses. These pulses create a more active chemical reaction within the battery. As a result, they facilitate faster charging while reducing the risk of overheating. In pulse charging, battery preparation occurs before any electrical activity begins. It involves
The result of regeneration is based on how much the structure of the battery is damaged. There are several ways to secure pulse charging like programmable power supply or circuits for shaping and limitation of charging current. In this article, these options are described.

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.
Pulse charging can improve battery performance in several ways. Firstly, in low-temperature environments, the pulse-charging method can effectively preheat the battery. Some specific pulse parameters, such as cut-off voltage and pulse frequency, have been studied, revealing their impact on the preheating effect, and temperature rise .
Pulse Charging Pulse charging involves using carefully selected and controlled charge current pulses to charge a battery. Figure 3 a shows a macromodel of a pulse charger where by controlling the switch, Sw, charge current, Ic, is pulsed into the battery.
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.
The pulse charge mode uses a pulse current (2C -1C at 0.05Hz) to charge the battery to the cut-off voltage of 3.6V, followed by CV charging till the current drops to 0.1C. After this, the battery rests for 1 h, then discharges to 2V at 0.5C, followed by another 1-h rest.
