[0078] In some specific embodiments of the present disclosure, referring to FIG. 6, the single-phase AC terminal 41 and the three-phase AC terminal 31 in the power converter 200 can be electrically connected through the AC connecting terminal 51, and the first neutral terminal 32 and the second neutral terminal 42 can be electrically connected through the neutral connecting terminal 52.

As shown in FIGS. 8 and 10, the second terminal assembly 40 is configured as a terminal in the AC / DC plug (European standard plug). The AC / DC plug (European standard plug) can adapt to the European standard vehicle charging socket. The AC / DC plug is connected with the AC / DC socket to form an integrated structure. By using the power converter 200 of this embodiment, the US standard charging pile can be adapted to the European standard vehicle, the effective charging of the European standard vehicle on the US standard charging pile can be realized, and the convenience of vehicle charging for users can be improved.

[0086] Therefore, in the embodiments of FIGS. 7-11, taking the first standard as the US standard and the second standard as the European standard as an example, the shell 10 is configured with the first terminal assembly 30 as an AC / DC socket (for example, a US standard socket), and the shell 10 is configured with the second terminal assembly 40 as an AC / DC plug (for example, a European standard plug). Among them, the AC / DC plug is mainly composed of three-phase AC terminals 411, a second neutral terminal 42, a second DC positive terminal 43, and a second DC negative terminal 44. The single-phase AC terminal 211 (US standard live wire end L) is connected with the three-phase AC terminal 411 (European standard live wire end N), and the first neutral terminal 32 (US standard zero line end L) is connected with the second neutral terminal 42 (European standard zero line end N). The single-phase AC terminal 211 and the first neutral terminal 32 are used to provide US standard end AC current, the three-phase AC terminal 411 and the second neutral terminal 42 are used to provide European standard end AC current, and the AC charging mode of the vehicle is realized. The first DC positive terminal 33 is connected with the second DC positive terminal 43, and the first DC negative terminal 34 is connected with the second DC negative terminal 44.

Thus, according to the power converter 200 of the present embodiment, the AC / DC socket for connecting the American standard charging pile plug and the AC / DC plug for connecting the European standard vehicle charging socket are integrated, which can effectively utilize the American standard charging pile to charge the European standard vehicle. At the same time, the single-phase AC terminal 211, the three-phase AC terminal 411, the first neutral terminal 32, the second neutral terminal 42, the first DC positive terminal 33, the first DC negative terminal 34, the second DC positive terminal 43, and the second DC negative terminal 44 are arranged in the power converter 200, which can not only meet the AC charging mode from the American standard to the European standard, but also simultaneously have the DC charging mode, increasing the application scenarios of the power converter 200. Therefore, the power converter 200 of the present embodiment converts, for example, the American standard vehicle charging interface to the European standard automobile charging interface, when charging the European standard electric vehicle, first connect the converted charging socket (American standard socket) with the American standard charging pile plug, and then insert the converted charging plug (European standard plug) into the charging socket of the European standard electric vehicle to achieve charging without additional operations, thereby making the European standard vehicle and the American standard charging pile have a better application range, and the application of such a portable product is conducive to the popularization and application of electric vehicles.
