摘要：
In theory, the cycle life of a LiFePO4 battery is more than 2000 times. However, in practical applications, this does not consider the influence of change conditions on the cycle life of the battery. In this paper, the charge characteristics and capacity fading mechanism of the LiFePO4 power battery are analyzed and studied. Based on the influence of charge cut-off voltage on charge speed and cycle life, a criterion method of the LiFePO4 power battery charging end has been proposed. Experimental results show that charge end dynamic criterion not only guaranties the charge rate, but also limits the risk of damaging the power battery, which means the cycle life of the power battery is prolonged.
