Embodiment Construction

[0026] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0027] In the embodiment, for PHEV models without DC charging function, the dual interface of DC and AC charging is expensive, and it is not suitable as a transitional solution. A charging adapter with DC charging function is used. When the vehicle is charged with DC, such as figure 1 As shown, the physical connection between the DC charging equipment and the vehicle-mounted single-phase AC charging socket is realized by means of transfer connection, so as to realize the DC charging function of the DC charging equipment for the vehicle. The direct-to-ac charging adapter mainly connects the terminals of the DC charging equipment through The physical structure is transferred to the terminal of the single-phase AC charging socket on the vehicle, and the chargi...

Abstract

The invention provides a vehicle-mounted single-phase alternating-current charging socket, a vehicle and a method for identifying the charging and discharging mode of the vehicle. The vehicle-mounted single-phase alternating-current charging socket comprises: a socket body; a charging terminal which is arranged corresponding to each charging interface, wherein a first phase alternating current terminal and a neutral line terminal are both used for transmitting power supply charging and discharging signals; a microswitch, wherein the microswitch is arranged at a charging interface corresponding to a second phase alternating current terminal and is electrically connected with the second phase alternating current terminal, or the microswitch is arranged at a charging interface corresponding to a third phase alternating current terminal and is electrically connected with the third phase alternating current terminal, the microswitch is used for being triggered by a communication terminal of a direct-to-alternating charging adapter when a vehicle-mounted single-phase alternating-current charging socket is connected with the direct-to-alternating charging adapter in a matched mode and sending a direct-current charging trigger signal. According to the vehicle-mounted single-phase alternating current charging socket, the charging mode can be recognized, and the charging safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle-mounted single-phase AC charging socket, a vehicle and a method for identifying a charging and discharging mode of the vehicle. Background technique [0002] With the rapid development of new energy vehicles, various companies develop PHEV (Plug-in hybrid electric vehicle, plug-in hybrid electric vehicle) accounted for a high proportion, related charging facilities such as AC charging pile, DC charging pile and AC-DC integrated charging pile Also building steadily. Moreover, there are many domestic passenger car companies, and when there are many PHEV models to choose from, the charging rate of the same price model has become one of the main factors for users to purchase cars. [0003] At present, PHEV charging modes can be divided into AC charging and DC charging according to the current type. In order to provide users with more charging mode options, it is very nece...
