The invention relates to the technical field of vehicle-mounted charging. The invention discloses a charging system and method capable of automatically switching power. The system comprises a chargingpile and a vehicle-mounted charger; the charging pile is used for obtaining a current power gear level. The charging pile is used for receiving the current power gear level and determining a corresponding pulse signal according to the current power gear level, the charging pile is further used for sending the pulse signal to the corresponding vehicle-mounted charger, and the vehicle-mounted charger is used for receiving the pulse signal, adjusting the current charging power according to the pulse signal and charging according to the adjusted current charging power. A corresponding pulse signal is sent to the vehicle-mounted charger through the charging pile according to the current power gear level, so that the vehicle-mounted charger automatically adjusts the current charging power according to the pulse signal to realize automatic switching of the vehicle-mounted charging power. Potential safety hazards existing in an existing alternating-current charging pile are avoided, chargingsafety and user experience are improved, and unnecessary energy waste is reduced.
