This helps reduce the development cost of charging equipment and is suitable for the rapid promotion and use of high-voltage electric vehicles.

[0003] However, for low-voltage electric products, there are currently no unified standards for their corresponding charging equipment interfaces and charging protocols. Charging equipment interfaces include the national standard charging interface for standard charging guns and the REMA charging interface for REMA charging guns. Charging protocols include manufacturer-defined protocols and national standard charging protocols. As a result, current low-voltage electric products are all equipped with specific charging equipment, and different charging equipment are not compatible with each other. This leads to high development costs for charging equipment and hinders the widespread adoption of low-voltage electric products. Utility Model Content

[0023] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See Figure 1 , Figure 3 and Figure 5 This utility model provides a charging device, including: a device body 1, a national standard charging gun 2, and a REMA charging gun 3. The national standard charging gun 2 and the REMA charging gun 3 are both installed on the device body 1. The device body 1 is provided with a power supply module. The national standard charging gun 2 and the REMA charging gun 3 are arranged in parallel and are both connected to the power supply module.

[0027] The power supply module in the main body 1 includes a charging module, relays, fuses, a control board, copper busbars, etc., used to charge low-voltage electric products via a standard charging gun 2 or a REMA charging gun 3. Both the standard charging gun 2 and the REMA charging gun 3 are installed on the rear end of the main body 1 and extend into the internal power supply module. Thus, the standard charging gun 2 and the REMA charging gun 3 are connected in parallel and both are connected to the power supply module of the main body 1. The standard charging gun 2 has a single-gun charging current of 250A and a protection rating of typically IP55, making it more expensive. The REMA charging gun 3 has a single-gun charging current of 300-400A and a protection rating of typically IP21, making it less expensive. When customers require fast charging, low cost, and low protection, the REMA charging gun 3 is used to connect the corresponding low-voltage electric product. When customers require outdoor use, high protection, and low cost, the standard charging gun 2 is used. Based on this, customers can choose the appropriate national standard charging gun 2 or REMA charging gun 3 according to the characteristics of low-voltage electric products to meet the needs of different customers, greatly reducing the development cost of charging equipment and facilitating the promotion and use of low-voltage electric products.

[0028] See Figure 4 and Figure 6 The standard charging gun 2 has a standard charging interface 21 at one end away from the main body 1, and the REMA charging gun 3 has a REMA charging interface 31 at one end away from the main body 1. When customers have charging needs that are fast, low-cost, and have low protection requirements, the REMA charging interface 31 of the REMA charging gun 3 is used to connect to the corresponding low-voltage electric product. When customers have charging needs that are for outdoor use, have high protection, and have low cost requirements, the standard charging interface 21 of the standard charging gun 2 is used to connect to the corresponding low-voltage electric product.

[0029] The power supply module adopts the national standard charging protocol, and both the national standard charging interface 21 and the REMA charging interface 31 are compatible with the national standard charging protocol. Referring to Table 1 below, both the national standard charging interface 21 and the REMA charging interface 31 are equipped with DC power supply positive DC+, DC power supply negative DC-, ground wire PE, charging communication CAN+ terminal S+, charging communication CAN- terminal S-, charging connection confirmation CC1, charging connection confirmation CC2, low-voltage auxiliary power supply positive A+, and low-voltage auxiliary power supply negative A-. Since the power supply module of the charging equipment adopts the same national standard charging protocol as high-voltage new energy charging equipment, it can achieve the same charging function as high-voltage new energy charging equipment. In the future, only the low-voltage power supply module inside the equipment body 1 needs to be replaced with a high-voltage power supply module, that is, replaced with electrical components such as high-voltage relays and fuses, to convert the low-voltage charging equipment into a high-voltage charging equipment. This has the characteristics of convenient modification and upgrading, and is conducive to reducing development costs and shortening the development cycle.

[0032] In addition, see Figure 1 The top of the device body 1 is provided with a lifting lug 4, and the lifting lug 4 has a lifting hole 41. The lifting lug 4 is designed to facilitate the lifting of the device into the lifting hole 41, so as to realize the lifting of the charging device and thus facilitate the transfer of the charging device to different usage scenarios at different heights.

[0033] Lifting lugs 4 are provided at both ends of the device body 1 in the width direction, and the lifting holes 41 of the two lifting lugs 4 are correspondingly provided. The lifting lugs 4 are provided with two lifting holes 41 at intervals along the length direction. The relative arrangement of the lifting lugs 4 and the interval arrangement of the two lifting holes 41 are conducive to the stable lifting of the charging equipment and to keeping the charging equipment stable, so as to prevent damage to the charging equipment.

[0034] Furthermore, a support frame 5 is provided at the bottom of the device body 1. The support frame 5 is arranged around the circumferential edge of the bottom surface of the device body 1, and a fork hole 51 is provided along the width direction of the support frame 5. The support frame 5 facilitates the stable placement of the charging device on the platform surface, and the fork hole 51 is designed to be compatible with forklifts, so as to facilitate the transfer of the charging device by forklift.

[0035] See Figure 2 The bottom of the device body 1 is equipped with rollers 6, which are distributed at the four corners of the bottom of the device body 1. The rollers 6 facilitate the movement of the charging device, making it easy to push the charging device to the place of use.
