Abstract

The invention discloses a boost charging control method and device. The method comprises the following steps: acquiring an insulation detection voltage of a charging pile and a maximum allowable voltage of the charging pile; if the charging pile insulation detection voltage and the charging pile maximum allowable voltage meet a preset judgment condition, the vehicle is controlled to enter a direct connection charging mode; in the direct connection charging mode, the current voltage of a vehicle battery pack is obtained; and if the current voltage of the battery pack meets the preset switching condition, the vehicle is controlled to be switched from a direct connection charging mode to a boost charging mode. According to the method, intelligent and accurate judgment of the output capacity of the charging pile is achieved, a dynamic optimization charging strategy is implemented in the single charging process, and the problems that the charging compatibility of a high-voltage platform vehicle type is poor, and the charging efficiency is limited by a traditional boosting scheme are solved.
