A vehicle charging switching method. When a first charging circuit (10) is used to perform direct current charging on a power battery (B), before switching to a second charging circuit (20) to perform boost charging on the power battery (B), a charging controller (30) can control the first charging circuit (10) to pre-charge a pre-charge unit (21) in the second charging circuit (20), and upon detecting that the voltage of the pre-charge unit (21) matches the voltage of the power battery (B), the charging controller (30) controls the second charging circuit (20) to perform boost charging on the power battery (B). Hence, when boost charging is to be performed on a power battery, it is not necessary to exit the charging process and insert the charging connector and swipe the card again, achieving seamless, uninterrupted switching from direct current charging of the power battery to boost charging of the power battery, thus improving the charging efficiency of the power battery and meeting user requirements for a single charging process. Further disclosed are a vehicle charging switching system, a computer-readable storage medium, a charging controller, and a vehicle.
