As batteries become more prevalent in grid energy storage applications, the controllers that decide when to charge and discharge become critical to maximizing their utilization. Controller design for these applications is based on models that mathematically represent the physical dynamics and constraints of batteries.
Batteries consist of two electrical terminals called the cathode and the anode, separated by a chemical material called an electrolyte. they convert this chemical potential energy to electricity in the circuit and discharge the battery. During charging or discharging, the oppositely charged ions move inside the battery through the

Additionally, the NBT-CZT ceramics had a fast discharge speed (t 0.9 < 100 ns) and high power density (24.2 MW/cm 3, E = 100 kV/cm, x = 0.15), and the charge-discharge process remained stable even when the measured temperature was up to 160°C.
