Charging and discharging interface, method, charging pile, and electronic device for vehicle-mounted AC charging and discharging machine

Abstract

The invention discloses a charging and discharging interface, a method, a charging pile, and an electronic device for a vehicle-mounted AC charging and discharging machine. The charging and discharging method for the vehicle-mounted AC charging and discharging machine comprises the following steps: detecting whether a vehicle-mounted control confirmation interface receives confirmation signals ornot when detecting that a vehicle-mounted charging connection confirmation interface triggers charging gun insertion signals; if receiving confirmation signals using a first duty ratio, performing a standard charging process, and if receiving confirmation signals using a second duty ratio, transmitting a bus communication signal to the charging pile, and entering a bus communication mode, whereinthe second duty ratio (95%) is different from the first duty ratio (5% to 90%); in the bus communication mode, performing a handshake flow, a parameter setting flow and a charging and discharging flowthrough a vehicle-mounted bus communication interface and the charging pile. By modifying the duty ratio of the confirmation signals, a vehicle is guided to be communicated with the charging pile byusing a CAN bus, thereby establishing a more reliable data interaction mode.

Description

technical field [0001] The invention relates to the technical field related to electric vehicles, in particular to a charging and discharging interface of a vehicle-mounted AC charging and discharging machine, a method, a charging pile, and electronic equipment. Background technique [0002] Due to the gradual development of electric vehicles, charging has become a large load on the grid. Due to the limited load of the grid, it will lead to overload of the grid load and stop power supply. Suppose, after 10 years, Chengdu has a population of 10 million, and there are 1 million new energy vehicles equipped with 20kw chargers. If all users charge at the same time at night, it will consume 20 million watts, which is equivalent to the power generation of a Three Gorges Dam. [0003] Therefore, it is an imminent task to avoid charging during peak power consumption in cities, and to be able to export electricity from vehicles during peak power consumption. [0004] However, the e...
