The invention relates to a charging control method, device and equipment and a storage medium, and relates to the technical field of automobiles. The method comprises the steps that when a vehicle battery is connected with a charging pile, it is determined that the step-down output voltage of an energy conversion device is reduced to a first charging voltage within a preset duration; controlling the energy conversion device to be in a boost mode, and adjusting the boost output voltage to be a first output voltage and the boost output current to be a first charging current; and when it is determined that the charging pile outputs the current, the output voltage of the charging pile is increased to a second output voltage, and when it is determined that the maximum rated voltage of the charging pile is smaller than the preset voltage, the vehicle battery is charged through the charging pile. Therefore, boost charging or direct current charging can be carried out on the vehicle battery based on the maximum rated
