Stable power can prolong the service life of DC charging pile.In order to improve the stability and coincidence of DC charging pile power control,an automatic optimization control system of DC charging pile power based on orthogonal test method is proposed.The hardware design of the system is completed by designing the pulse width modulation signal sampling circuit,the driving circuit of DC charging pile power automatic optimization control and DC charging pile power automatic optimization controller.In the software design of the system,the charging power of DC charging pile is adjusted by orthogonal test method.By formulating the automatic optimization control strategy of DC charging pile power,the automatic optimization control of DC charging pile power is realized.The test results show that the system has good stability and coincidence in the power control of DC charging pile,the difference between control power and ideal power is less than 15.6 W,and the mean square error is less than 0.28.
