The invention discloses a power supply circuit and a vehicle. The power supply circuit comprises a power supply, an anti-reverse connection circuit, a first filter circuit, a second filter circuit and a filter inductor, the power supply is connected in series with the anti-reverse connection circuit, the first filter circuit and the second filter circuit. The first filter circuit and the second filter circuit are used for filtering high-frequency interference signals in the power supply circuit; the first filter circuit is electrically connected with the input end of the filter inductor, and the second filter circuit is electrically connected with the output end of the filter inductor; the first filter circuit and the second filter circuit are connected in parallel; the first filter circuit and the second filter circuit respectively comprise at least two ceramic capacitors which are connected in series, and the at least two ceramic capacitors which are connected in series are arranged on the circuit board in a mutually perpendicular mode. Short circuit of the power supply circuit caused by stress can be effectively avoided, high-frequency interference signals in the power supply circuit can be filtered out, and reliability and stability of the power supply circuit are improved.
