Description

Technical Field

[0001] The utility model relates to the technical field of teaching tools, in particular to a new energy vehicle battery pack function demonstration teaching device. Background Art

[0002] With the rapid development of new energy vehicle technology in recent years, the popularization of new energy technology has become increasingly important. Power battery packs are an important part of new energy vehicles. It is particularly important to understand the structure, functions and working principles of power battery packs. It will also play a very important role in the production, manufacturing, maintenance, and repair of power battery packs in the future.

[0003] However, due to the lag in the professional settings of colleges and universities or technical colleges in various places, most schools have not yet set up majors related to new energy vehicles, resulting in a serious lag in the teaching of new energy vehicles. The teaching equipment and teaching aids related to this major are also extremely scarce. Even if some vocational high schools or universities want to carry out new energy vehicle teaching, the lack of corresponding teaching aids makes it difficult for students to understand the corresponding new energy vehicle teaching content, and the teaching quality is difficult to improve.

[0004] In this regard, in order to more intuitively demonstrate the structure and functional characteristics of the power battery pack in the new energy vehicle, the applicant school had to purchase new energy vehicles and their power battery packs and move them into the classroom to facilitate teaching. However, the power battery packs are expensive and the procurement cost is high, making it difficult to implement them on a full scale. In addition, the power battery packs have high voltage and large current during operation, posing a major safety hazard and various defects, making them difficult to popularize. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a new energy vehicle battery pack function demonstration teaching device which has low procurement cost, high safety and can intuitively display various working states and current and voltage of the power battery pack.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a new energy vehicle battery pack function demonstration teaching device, comprising a shell for installing the battery pack, a battery management unit and a frame for fixing the shell, a plurality of battery modules arranged in an array are installed in the shell, the shell is equipped with a control board and a plurality of flowing light strings electrically connected to the control board, one end of the plurality of flowing light strings is connected to the plurality of battery modules one by one, and the other end of the flowing light strings is connected to the battery management unit, and the control board is installed inside.

[0007] Preferably, the battery module is replaced by a transparent model, and the wires between the battery module and the battery management unit are replaced by the flowing light string.

[0008] Preferably, a transparent heat exchange tube is provided between adjacent battery modules, and a water light string for simulating coolant is passed through the transparent heat exchange tube.

[0009] Preferably, the flowing light string includes a flexible circuit and a plurality of LED lamp beads spaced apart on the flexible circuit. Under the control of the control board, the plurality of LED lamp beads are repeatedly lit and turned off in sequence.

[0010] The beneficial effect of the present invention is that: the present invention provides a new energy vehicle battery pack function demonstration teaching device. During the actual teaching demonstration process, when the power battery pack is discharging to the outside, multiple water flow light strings simultaneously produce a visual effect of water flowing to the battery management unit, simulating the output of electric energy; when the new energy vehicle is charging, multiple water flow light strings simultaneously produce a visual effect of water flowing from the battery management unit to each battery module, simulating the input or replenishment of electric energy, so that students can simply and intuitively understand the internal structure, working principle and various energy efficiency flow states of the power battery pack. Students can understand the teaching content more quickly, the teaching quality is higher, and the practicality is stronger. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the embodiments. The contents mentioned in the embodiments are not intended to limit the present invention.

[0015] like Figures 1 to 3 As shown, a new energy vehicle battery pack function demonstration teaching device includes a shell 1 for installing the battery pack, a battery management unit 5 and a frame 2 for fixing the shell 1. A plurality of battery modules 3 arranged in an array are installed in the shell 1. The shell 1 is equipped with a control board for controlling the display effect and a plurality of flowing light strings 6 electrically connected to the control board for simulating current. One end of the plurality of flowing light strings 6 is connected to the plurality of battery modules 3 in a one-to-one correspondence, and the other end of the flowing light strings 6 is connected to the battery management unit 5. The control board is installed in the battery management unit 5.

[0016] During the actual teaching demonstration, when the power battery pack is discharging, multiple water light strings 6 simultaneously produce the visual effect of water flowing toward the battery management unit 5, simulating the output of electric energy; when the new energy vehicle is charging, multiple water light strings 6 simultaneously produce the visual effect of water flowing from the battery management unit 5 to each battery module 3, simulating the input or replenishment of electric energy, allowing students to understand the internal structure, working principle and various energy efficiency flow states of the power battery pack in a simple and intuitive way. Students can understand the teaching content more quickly, and the teaching quality is higher and more practical.

[0017] In this embodiment, the battery module 3 is replaced by a transparent model, and the wires between the battery module 3 and the battery management unit 5 are replaced by the flowing light string 6. The replacement structural design of the transparent model effectively reduces the production cost of the battery pack function demonstration teaching device. The flowing light string 6 is exactly the same as the wire layout structure, and can more realistically restore and demonstrate the transmission path and direction of electric energy, and is highly practical.

[0018] In this embodiment, a transparent heat exchange tube 7 is provided between adjacent battery modules 3. A water light string 6 for simulating coolant is passed through the transparent heat exchange tube 7. The color of the water light string 6 is different from the color of the water light string 6 for simulating current. The water light string 6 is used to distinguish the flow paths of current and coolant, which is convenient for helping students to distinguish and understand the flow paths of current and coolant during the teaching process, and the teaching quality is significantly improved.

[0019] In this embodiment, the flowing light string 6 includes a flexible circuit and a plurality of LED lamp beads spaced apart on the flexible circuit. Under the control of the control board, the plurality of LED lamp beads are repeatedly lit and turned off in sequence. The demonstration of the flowing light effect produced by repeatedly lighting and turning off the plurality of LED lamp beads in sequence is more intuitive, and the magnitude of the current or the flow rate of the coolant can be displayed according to the frequency of repeated lighting and turning off. The demonstration of teaching content is more intuitive, which greatly reduces the difficulty of understanding in teaching and is highly practical.
