![]() ![]() These algorithms provide less charging time in comparison with the conventional constant current–constant voltage (CC–CV) methods. The fastest and the most effective algorithms can be categorised into three main algorithms, which are boost charging algorithm, multi-step charge pattern and pulse charging methods. ![]() Owing to the low speed of the charging process of the battery, due to its low-power density, in recent years, many fast charging algorithms have been proposed. The battery is one of the main parts of storage systems in order to store and deliver energy. In recent years, energy storage equipment has been mostly used for different applications such as low-power portable electronic devices, high-power battery energy storage systems and electric vehicles. Both simulation and experimental results show the effectiveness of the proposed algorithm and control system to track SRC reference current in all frequencies. In addition, results of the conventional proportional–integrator (PI) controller have been compared with the proposed controller. The proposed pole placement control method for tracking of SRC and the optimal frequency detection algorithm have been designed and tested on a practical 10 Ah Li iron phosphate battery pack in different charge modes. Also, simulations have been carried out by Simulink/MATLAB. To evaluate the design, a laboratory setup has been implemented to obtain experimental results from a 1 kW Li-ion battery pack. This study, the impact of temperature has been considered as a protection criterion in the proposed charge algorithm, also a state-space model of the charger system has been developed, and finally a pole placement controller has been proposed to control charging current. By choosing the appropriate frequency, the minimum AC impedance of the battery is obtained. In this method, a combination of a DC and a sinusoidal ripple current is injected to the battery. ![]() This study presents a control system to track the sinusoidal ripple current (SRC) of lithium (Li)-ion batteries.
