The invention provides a vehicle-mounted bidirectional charger and a vehicle-mounted bidirectional power supply method and device. The vehicle-mounted bidirectional power supply method includes the steps of receiving a resistance value detected at a resistance detection interface of a trickle charge port and a voltage value detected at a control and guide interface of the trickle charge port within a preset period of time when a control and guide circuit connected with the vehicle-mounted bidirectional charger is in a first state, and controlling a first control switch connected with a power supply interface of the trickle charge port and a second switch connected with an electric socket to be in a closed state according to the resistance value and the voltage value when it is determined that the vehicle-mounted bidirectional charger is in an inversion mode, wherein the first control switch is connected with the second control switch, the first control switch and the second control switch are both connected with the vehicle-mounted bidirectional charger, and the vehicle-mounted bidirectional charger is connected with a power battery. According to the vehicle-mounted bidirectional charger and the vehicle-mounted bidirectional power supply method and device, electricity with higher power can be provided for the electric socket to meet electricity utilization of more high power loads in a vehicle, and the whole vehicle cost is reduced.
Description
Technical field [0001] The invention relates to the field of automobile charging, in particular to a vehicle-mounted two-way charger, a vehicle-mounted two-way power supply method and device. Background technique [0002] The on-board 220VAC power supply devices mounted in mid-to-high-end passenger cars, commercial vehicles and some SUV models generally take power from 12V or 24V low-voltage batteries and convert them into 220VAC power through a dedicated inverter unit, such as figure 1 Shown. The problems with the power supply mode of the 22VAC electric socket in the prior art include: 1. The 220VAC electric power converted by this inverter unit is low due to the small capacity of the 12V or 24V low-voltage battery, which is generally within 200W. Satisfy users' demands for higher power appliances. [0003] 2. In order to realize the function of providing 220VAC electricity, a dedicated inverter unit is required, which increases the cost of the vehicle. Summary of the invention ...
