Problems solved by technology
If double-layer battery modules are used in the cabinet, it is necessary to design and install the upper module fixing bracket, and then use long bolts to fix the upper battery module. The structure design is complicated and the strength is not high; The wiring harness needs to be connected to each other or to the corresponding controller through manual installation. The installation and removal are cumbersome and inefficient

Embodiment Construction
[0091] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.
[0092] The battery pack in the present invention is suitable for the battery pack of an electric vehicle. The structure and voltage of the low-voltage output end and the high-voltage output end of the battery pack 1 all refer to the relevant parameters of the battery pack of the electric vehicle. The output terminal supplies power to the electric motor of the car, and will not be described in detail later.

The invention provides a battery quick-changing system and an electric vehicle. The battery quick-changing system comprises a battery system shell, at least one first connecting beam, at least one pair of second connecting beams, a plurality of battery packs, a high-voltage output module and a low-voltage output module; the at least one first connecting beam is arranged in the battery system shell; the at least one pair of second connecting beams are arranged in the battery system shell, the second connecting beams are distributed on the two sides of each first connecting beam at intervals and are parallel to the first connecting beams, and the first connecting beams and the second connecting beams jointly form a mounting plane; the plurality of battery packs are arranged in two rows and are arranged on the upper side of the mounting plane, and the battery packs are detachably and mechanically connected with one sides of the first connecting beams and the second connecting beams adjacent to the sides; the high-voltage output module and the low-voltage output module are arranged on the lower side of the mounting plane, the high-voltage output end of each battery pack is detachably and electrically connected with the high-voltage output module, the high-voltage output end of each battery pack is detachably and electrically connected with the low-voltage output module, and electrical connection and mechanical connection are carried out synchronously. The battery quick-changing system has the advantages of high integration, quick and easy installation / disassembly, high strength and small size.
Description
technical field [0001] The invention relates to the field of in-vehicle electrical connectors, in particular to a battery quick-change system and an electric vehicle. Background technique [0002] The existing power battery module includes a low-voltage output terminal that supplies power to the electronic system of the car and a high-voltage output terminal that supplies power to the motor of the car. The power battery module generally has an end plate at each end, and the end plate is made of extruded aluminum. The profile is machined, and the circular or oblong hole extruded on the profile is the installation hole of the power battery module. The mechanical connection uses long bolts to fix the battery module in the box through the module installation hole. If double-layer battery modules are used in the cabinet, it is necessary to design and install the upper module fixing bracket, and then use long bolts to fix the upper battery module. The structure design is complicat...
