Fast charging method of lithium battery based on Taguchi method

Based on the working principle and charging and discharging characteristics of lithium battery, in order to balance the charging efficiency of lithium battery and eliminate its polarization relationship, a fast charging method of lithium battery based on Taguchi method is studied. By orthogonal experiment, and the optimization of fuzzy controller is established that five order current value, depolarizing pulse amplitude and pulse interval time, and ultimately eliminate the negative pulse width and the polarization time, so as to realize the fast charging lithium battery, and through the experiment of this method was verified. The results show that the method of fast charge of lithium battery based on Taguchi method is effective, compared with the traditional method, the speed is increased by 8.89%, the efficiency is improved by 0.6% and the heat is reduced by 17.6%.
