The invention discloses a vehicle-mounted charger with wireless power access and capable of realizing bidirectional energy flow. The vehicle-mounted charger with wireless power access and capable of realizing bidirectional energy flow is characterized in that a wireless receiving and compensating module outputs alternating current by generating an alternating magnetic field in a wireless chargingmode, and an alternating current input end outputs alternating current on an alternating current power grid in a wired charging mode; the wireless receiving and compensating module and the alternatingcurrent input end are switched through a first switching module, a first adjusting circuit can convert alternating current into direct current and invert and convert the direct current into alternating current, and a second switching module is used for connecting a bus with a storage battery in a wireless charging mode, and is further used for connecting the bus with the direct-current adjustingcircuit in a wired charging mode, converting the voltage on the bus into a first preset voltage through the direct-current adjusting circuit and outputting the first preset voltage to the storage battery, and the direct-current adjusting circuit can further convert the voltage of direct current output by the storage battery into a second preset voltage; therefore, the vehicle-mounted charger meetstwo requirements of wireless charging and wired charging, and meanwhile, bidirectional flow of power flow is realized.

    一种具备无线功率接入的可双向能量流动的车载充电机,无线充电模式下无线接收和补偿模块通过产生交变磁场而输出交流电,有线充电模式下交流输入端输出交流电网上的交流电,并通过第一切换模块对无线接收和补偿模块和交流输入端之间进行切换,第一调节电路能够将交流电转换为直流电,还能够将直流电逆变转换为交流电,第二切换模块用于在无线充电模式下将母线与蓄电池连接,还用于在有线充电模式下将母线与直流调节电路连接,通过直流调节电路将母线上的电压转换为第一预设电压后输出至蓄电池,直流调节电路还能够将蓄电池输出的直流电的电压转换为第二预设电压,使得车载充电机满足无线充电和有线充电两种需求的同时,实现了功率流的双向流动。
