The invention discloses an intelligent charging method for a lithium ion power battery. The intelligent charging method comprises the following steps: constructing a battery fast charging simulation model and acquiring parameters; acquiring an initial charging safety boundary of the battery; verifying the initial charging safety boundary through a lithium ion power battery full life cycle data test platform to obtain a target charging safety boundary; according to the target charging safety boundary, calculating a final optimal solution of multiple targets of battery fast charging through an improved genetic algorithm to obtain a first fast charging strategy; the first fast charging strategy is optimized according to the pulse width, a final target fast charging strategy is obtained, and the final target fast charging strategy obtained through the overall steps can shorten the charging time of the lithium ion power battery, reduce temperature rise, delay the service life of the battery and reduce energy loss during charging. The method can be widely applied to the technical field of rapid battery charging optimization.
