Power supply equalization optimization method and power supply equalization optimization system

The invention provides a power supply equalization optimization method and a power supply equalization optimization system, and the method comprises the steps: monitoring and collecting the parameters of a battery cell in real time, calculating the capacity and internal resistance of the battery cell according to the parameters, obtaining a charge state prediction value through employing an improved adaptive Kalman filtering algorithm, and carrying out the equalization optimization of the power supply. Taking a comprehensive unbalance degree formed by combining the consistency of the charge state, the cell voltage and the cell internal resistance as a target function, and obtaining a real-time equalization strategy by adopting a firefly optimization algorithm; and according to the power supply system fault state, the cell temperature, the cell voltage and the cell state, judging whether each cell needs to start equalization or not. According to the method, real-time regulation and control in different states
