The invention discloses a bidirectional energy conversion system of a new energy automobile, and belongs to the technical field of new energy automobiles. In order to solve the problem of energy conversion between a power grid and a new energy battery power supply, after power data are collected from the power grid, filtering processing is performed on the collected power data through an LCL filter and an L filter, and a high-frequency harmonic part and a low-frequency harmonic part in the power data are inhibited; the AD/DC converter is driven through a control algorithm to convert the filtered power data from alternating current to direct current, and the DC/DC converter is driven to convert the power data to adjust the voltage of the power data, so that the power data acquired from the power grid can be stored in a battery power supply of the new energy automobile; rapid energy conversion between a power grid and a new energy battery power supply is realized, and the overall energy utilization efficiency can be improved.
