The invention discloses a power supply circuit, an electric vehicle and a control method of the electric vehicle, and a wireless charging and discharging unit and a wired charging and discharging unit in the power supply circuit multiplex a parameter adjustable circuit, so that the parameter adjustable circuit can be adjusted in a wired charging and discharging mode and a wireless charging and discharging mode; the wired charging and discharging unit and the wireless charging and discharging unit both adopt parameter-adjustable circuits, so that the conversion of the resonant frequency of the power supply circuit can be realized, and the reuse rate of devices in the power supply circuit is improved. And the control unit in the power supply circuit can flexibly adjust the resonance parameter of the parameter-adjustable circuit, so that the resonance frequency of the power supply circuit is the same as the preset frequency in the current charging and discharging mode, the dynamic adjustment of the resonance frequency of the power supply circuit is realized, and the charging and discharging efficiency is improved. In the wireless charging and discharging mode, the wireless charging and discharging coil and the parameter adjustable circuit form parallel resonance, so that the power supply circuit is suitable for application occasions of constant-voltage charging and discharging.

    本申请公开了一种电源电路、电动车辆及其控制方法,由于电源电路中的无线充放电单元和有线充放电单元复用参数可调电路,因此在有线充放电模式下和无线充放电模式下,有线充放电单元和无线充放电单元均采用参数可调电路即可实现电源电路的谐振频率的变换,提高了电源电路中器件的复用率。且由于电源电路中的控制单元能够灵活调节参数可调电路的谐振参数,以使电源电路的谐振频率与当前充放电模式下的预设频率相同,由此实现电源电路的谐振频率动态调节,提高了充放电效率。由于在无线充放电模式下,无线充放电线圈和参数可调电路形成并联谐振,因此该电源电路适用于恒压充放电的应用场合。
