The invention provides a vehicle-mounted wireless charging method, a vehicle-mounted wireless charging system and a vehicle, and belongs to the technical field of vehicles. The method comprises the steps that a combined coil receives a first signal sent by a terminal and sends the first signal to a charging chip; the charging chip sends a first signal to the first control unit; the first control unit instructs the charging chip to be initialized under the condition that the first control unit is determined not to be a control unit adaptive to the type of the terminal based on the first signal; the first control unit inquires whether initialization of the charging chip is completed or not, and after it is determined that initialization of the charging chip is completed, a charging notification is sent to the second control unit; and the second control unit receives the charging notification and controls the bridge voltage conversion chip and the charging chip to charge. According to the scheme, it can be guaranteed that the control right is transferred after initialization of the charging chip is completed, and the situation that the charging chip is broken down is effectively reduced.
本申请提供了一种车载无线充电方法、车载无线充电系统及车辆,属于车辆技术领域。该方法包括:组合线圈接收终端发送的第一信号,向充电芯片发送第一信号;充电芯片向第一控制单元发送第一信号;第一控制单元在基于第一信号确定第一控制单元不是与终端所属类型适配的控制单元的情况下,指示充电芯片初始化;第一控制单元查询充电芯片是否初始化完成,在确定充电芯片初始化完成之后,向第二控制单元发送充电通知;第二控制单元接收充电通知,控制桥电压转换芯片和充电芯片进行充电。该方案能够保证在充电芯片初始化完成之后移交控制权,有效减少了充电芯片被击穿的情况。
