The embodiment of the invention provides a charging circuit and method of a vehicle, the vehicle, a storage medium and a program product. The charging circuit comprises a direct current charging port, a three-bridge-arm sub-circuit and a first filtering module. The three-bridge-arm sub-circuit comprises a first bridge arm, a second bridge arm, a third bridge arm, a first inductor, a second inductor and a third inductor; the direct current charging port is connected with the first end of the first inductor, the first end of the second inductor and the first end of the third inductor. The second end of the first inductor is connected with the midpoint of the first bridge arm, the second end of the second inductor is connected with the midpoint of the second bridge arm, and the third end of the third inductor is connected with the midpoint of the third bridge arm; the first filtering module, the first bridge arm, the second bridge arm and the third bridge arm are connected in parallel between the positive output end and the negative output end of the bus. By means of the circuit, compatibility of high-voltage charging and low-voltage charging can be achieved under the condition that the cost of the whole vehicle is not increased.
