The invention relates to a battery circuit, a battery system and a vehicle. The battery circuit comprises a first battery module, a second battery module, a first switch unit and a second switch unit, wherein the first switch unit has a first closed state and a second closed state; the second switch unit has a third closed state and a fourth closed state; when the first switch unit is in a first closed state and the second switch unit is in a third closed state, the first battery module and the second battery module are connected in parallel; when the first switch unit is in a second closed state and the second switch unit is in a fourth closed state, the first battery module and the second battery module are connected in series. According to the battery circuit, the battery modules can be easily switched between parallel connection and series connection by changing the state of the switch unit, different load requirements are met, and efficient and reliable energy supply is achieved.
