The invention provides a charging system and method, a vehicle-mounted charger and a vehicle, and the method comprises the steps: switching the charging mode of the vehicle from a vehicle-mounted wired charging mode to a wireless charging mode through a mode switching switch, or switching the charging mode from the wireless charging mode to the vehicle-mounted wired charging mode, a rectification switch circuit, an inverter, an isolation circuit, a transformer and a rectifier can be reused for charging. According to the invention, the cost and the size of the charging system can be reduced by increasing the multiplexing number of components; moreover, the charging modes are switched through the mode switching switch, so that the redundancy of the charging system can be reduced, and the overall efficiency is improved. Since the rectification switch circuit, the inverter, the isolation circuit, the transformer and the rectifier comprise inductive elements and high-frequency full-bridge circuits, further multiplexing of the circuit module can be realized by multiplexing the inductive elements with large volume and high-cost high-frequency full-bridge circuits in the charging system, so that the cost can be reduced, and the space can be saved.

    本申请提供一种充电系统及充电方法、车载充电器及车辆,包括:通过提供模式切换开关将车辆的充电模式从车载有线充电模式切换至无线充电模式,或者从无线充电模式切换至车载有线充电模式,可以复用整流开关电路、逆变器、隔离电路、变压器和整流器进行充电。本申请可以通过增加元器件的复用数量来降低成本和减少充电系统的体积;而且本申请通过模式切换开关进行充电模式切换,可以减少充电系统冗余,以提高整体效率。由于整流开关电路、逆变器、隔离电路、变压器和整流器包含感性元件和高频全桥电路,所以本申请通过复用充电系统中体积占比较大的感性元件和高成本的高频全桥电路,可以实现电路模块的进一步复用,从而可以降低成本,并节省空间。
