The invention relates to a charging voltage switching device, a control method and an automobile. The device comprises a voltage measurement module which is used for measuring the charging voltage amplitude of charging equipment; a voltage judgment module which is used for judging the charging and discharging switching state according to the charging voltage amplitude of the charging equipment; acharging and discharging platform switching module which is used for controlling on-off of the controllable switch group according to the charging and discharging switching state, namely controlling switching of the charging and discharging circuit among a series charging state, a parallel charging state and a discharging state; and a switching state monitoring module which is used for monitoringthe charging and discharging switching state of the charging and discharging circuit. The charging and discharging circuit comprises a first battery pack and a second battery pack. The voltage of thebattery pack is divided into two parts, and the logic relationship between the two parts of the battery pack is changed through the switching controller and the switch group, so that the voltage of the battery pack is increased and reduced, and switching of two voltage platforms is realized on the premise of ensuring the safety.
