The invention provides an intelligent battery state of health (SOH) detection method used for an electric vehicle sharing charging pile. The intelligent battery SOH detection method comprises steps that power battery data of user application is tracked, and the power battery data is categorized and stored; the actual measurement current, the end voltage, and the surface temperature of the power battery data are used as input samples, and the training data set of the power battery data is established, and then an LSSVM regression model is acquired; a power battery SOH training model is established according to parameters, and is used for health estimation of a current charging battery unit; a battery current maximum capacity is used as a SOH evaluation index, and a power battery SOH model is established, and is optimized; voltage, current, temperature, and time information of a database are transmitted to a monitoring platform by a communication protocol, and the monitoring platform is used to estimate the SOH of the battery. By adopting a big data analysis method, the establishing of the battery data model is completed, and during a charging process, SOH of energy storage systems of all of users is evaluated.
