The invention provides a vehicle-mounted charger and a vehicle charging system, and relates to the technical field of vehicles. A protocol conversion unit and a power management control unit are arranged in the vehicle-mounted charger, the protocol conversion unit is connected with the power management control unit, the power management control unit and the protocol conversion unit are both connected with a charging port of a vehicle, and the charging port is used for being connected with a charging pile. The power management control unit is used for outputting a power supply signal to the protocol conversion unit; the protocol conversion unit is used for obtaining a message initiated by the charging pile according to a first communication protocol after obtaining the power supply signal and completing power-on, and forwarding the message to the power management control unit according to a second communication protocol. According to the scheme, the electric vehicle can be adaptively matched with the charging piles with different charging standards through the vehicle-mounted charger, and the charging cost is reduced.
