Electric automobile, control method of charging system of electric automobile, storage medium and control device

The invention provides an electric automobile, a control method of a charging system of the electric automobile, a storage medium and a control device. The control method comprises the steps: detecting whether a fault signal that a DC/DC conversion module breaks down is obtained or not in a process that a charging pile charges a power battery; if so, enabling all fully-controlled switching tubes in the DC/DC conversion module to be switched off, and sending a power reduction instruction to the charging pile; judging whether the fault signal of the DC/DC conversion module is still obtained or not; if so, counting the frequency of acquiring the fault signal and the duration of the fault signal; and controlling the DC/DC conversion module or the DC/DC conversion module and the charging pile according to the frequency and the duration of the fault signal. According to the control method, when the DC/DC conversion module breaks down, the DC/DC conversion module can be protected, meanwhile,continuous charging can b
