Application of Improved PID Algorithm in the Battery Charge Control System

To improve the actual life of lead-acid batteries in communication systems and the existing charge controlled system, a new charge controlled system is designed based on PID regulation algorithm. For the actual control system, we improve the traditional PID algorithm, establish a digital model of PID algorithm and simulate the proposed algorithm by Simulink. Simulation results show that the high controlling speed and small error rate achieve the requirements of system controlling, and also is helpful to improve the life of battery.
