In an embodiment of the present application, when a vehicle detects a charging gun insertion signal of a charging gun of a charging pile inserted into a charging port in a scene of performing direct current fast charging, a first highest output voltage of the charging pile is obtained, and it is noted that the first highest output voltage is a determination value of pre-charging on a vehicle side and is mainly used for determining whether the vehicle needs to be charged in a boost charging manner, rather than an actual highest output voltage of the charging pile. In one embodiment, the step of obtaining the first highest output voltage includes: and after detecting the insertion signal of the charging gun, carrying out insulation detection on the charging pile, and determining the highest voltage of the charging pile detected in the insulation detection process as the first highest output voltage.

Specifically, in order to avoid the direct switching from affecting parts and the like, a charging demand message is sent to the charging pile according to the current voltage of the battery, after the charging pile receives the charging demand message, the output voltage is gradually increased according to the current voltage of the battery until the current voltage of the battery is reached, and then a second control signal is output to the boost control circuit, so that the boost control circuit is switched to a direct charging mode, the switching of the charging mode is completed, the vehicle and the charging pile are directly charged, the relay of the boost equipment is reduced, and the charging efficiency is further improved.
