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.

    本发明公开了一种新能源汽车的双向能量转换系统,属于新能源汽车技术领域。为解决电网和新能源电池电源之间能量转换的问题,从电网中采集电力数据后,分别通过LCL滤波器和L滤波器对采集的电力数据进行滤波处理,抑制电力数据中的高频谐波部分和低频谐波部分,并通过控制算法驱动AD/DC变流器将滤波处理的电力数据由交流电转换为直流电,以及驱动DC/DC变流器将电力数据进行转换调整电力数据的电压,使得从电网中获取的电力数据可以存储于新能源汽车的电池电源,实现电网和新能源电池电源之间能量的快速转换,能够提高整体能源利用效率。
