Abstract
Description
Technical Field
[0001] This invention relates to batteries, and more particularly to a model high-rate composite battery. Background Technology
[0002] With continuous technological advancements, users are demanding increasingly higher continuous output power from high-power products and batteries, especially in products like model racing vehicles. The performance improvement of high-rate batteries is progressing steadily, with little room for rapid advancement, failing to meet users' needs for high-power output. Currently, commercially available composite batteries have high self-discharge, consuming a significant amount of power even when not in use. Therefore, developing a high-rate composite battery for model racing vehicles has become a pressing issue for those skilled in the art. Summary of the Invention
[0003] The present invention addresses the above-mentioned shortcomings by providing a high-rate composite battery model.
[0004] The above-mentioned objective of the present invention is achieved through the following technical solution: a high-rate composite battery model, comprising a battery assembly, the high-rate composite battery model further comprising a supercapacitor assembly and an adapter plate, the adapter plate being provided with a positive copper tube for the battery assembly, a negative copper tube for the battery assembly, a positive copper tube for the supercapacitor assembly, and a negative copper tube for the supercapacitor assembly, the positive and negative terminals of the battery assembly being respectively connected to the positive copper tube for the battery assembly and the negative copper tube for the battery assembly, the positive and negative terminals of the supercapacitor assembly being respectively connected to the positive copper tube for the supercapacitor assembly and the negative copper tube for the supercapacitor assembly.
[0005] Furthermore, the positive copper tubes of the battery assembly and the supercapacitor assembly are arranged coaxially with a gap between them (no contact). Similarly, the negative copper tubes of the battery assembly and the supercapacitor assembly are arranged coaxially with a gap between them (no contact). In use, the positive copper terminal of the load product is inserted into the positive copper tubes of the battery assembly and the supercapacitor assembly, and the negative copper terminal of the load product is inserted into the negative copper tubes of the battery assembly and the supercapacitor assembly. This parallel connection allows the battery assembly to charge the supercapacitor assembly, which then provides the product with ultra-high power output, enabling the load product to unleash its high kinetic energy.
[0006] Furthermore, a buffer foam is provided between the battery assembly and the supercapacitor assembly.
[0007] Furthermore, the battery assembly includes at least one battery. When there are two or more batteries, they are connected in series, and buffer foam is provided between adjacent batteries.
[0008] Furthermore, the supercapacitor assembly includes at least one supercapacitor. When there are two or more supercapacitors, they are connected in series, and buffer foam is provided between adjacent supercapacitors.
[0009] Furthermore, the battery assembly, supercapacitor assembly, and adapter plate are all enclosed in a housing, and the housing is provided with through holes corresponding to the positive and negative copper tubes (positive copper tube of the battery assembly, negative copper tube of the battery assembly, positive copper tube of the supercapacitor assembly, and negative copper tube of the supercapacitor assembly).
[0010] The advantages of this invention compared to the prior art are:
[0011] 1. This composite battery combines the advantages of both a storage battery and a supercapacitor. The connection between the supercapacitor and battery modules utilizes an adapter plate and a separate copper tubing design, effectively overcoming the high-power output bottleneck of the storage battery and the issue of the supercapacitor consuming battery power when the composite battery is not in use. When the composite battery is connected to a load product, the storage battery and supercapacitor modules form a parallel connection. The storage battery immediately charges the supercapacitor, which then provides the product with ultra-high power output, allowing the product or equipment to unleash greater kinetic energy.
[0012] 2. This composite battery is easy to assemble and has low production costs. The battery module and the supercapacitor module are connected in series and parallel by welding each battery and supercapacitor through an adapter plate (soldering, resistance welding or laser welding is possible), and then the whole assembly is put into the shell to form an integrated modular product, which can realize mass production.

[0014] Figure 2 This is a top view of the present invention.
[0015] Figure 3 This is a schematic diagram of the structure of the present invention after it is enclosed in the outer shell. Detailed Implementation
[0016] The invention will now be described in further detail with reference to the accompanying drawings.
[0017] like Figure 1 , Figure 2 and Figure 3As shown, a high-rate composite battery model includes a battery assembly 1, a supercapacitor assembly 2, and an adapter plate 3. A first buffer foam 4 is provided between the battery assembly 1 and the supercapacitor assembly 2. The battery assembly 1 includes two batteries 101 connected in series, and a second buffer foam 5 is provided between the two batteries 101. The supercapacitor assembly 2 includes three supercapacitors 201 connected in series, and a third buffer foam 6 is provided between adjacent supercapacitors 201.
[0018] The adapter plate 3 is provided with a positive copper tube 301, a negative copper tube 302, a positive copper tube 303, and a negative copper tube 304 of the battery assembly. The positive and negative terminals of the battery assembly 1 are respectively connected to the positive copper tube 301 and the negative copper tube 302 of the battery assembly, and the positive and negative terminals of the supercapacitor assembly 2 are respectively connected to the positive copper tube 303 and the negative copper tube 304 of the supercapacitor assembly.
[0019] The positive copper tube 301 of the battery assembly and the positive copper tube 303 of the supercapacitor assembly are arranged coaxially and separated by a first gap 305 (non-contact). The negative copper tube 302 of the battery assembly and the negative copper tube 304 of the supercapacitor assembly are arranged coaxially and separated by a second gap 306 (non-contact). In use, the positive copper post of the load product is inserted into the positive copper tube 301 of the battery assembly and the positive copper tube 303 of the supercapacitor assembly, and the negative copper post of the load product is inserted into the negative copper tube 302 of the battery assembly and the negative copper tube 304 of the supercapacitor assembly. This allows the positive and negative copper tubes of the battery assembly 1 and the supercapacitor assembly 2 to operate in parallel. After parallel connection, the battery assembly 1 will charge the supercapacitor assembly 2 with electrical energy, and then the supercapacitor assembly 2 will provide the product with ultra-high power output capability to realize the high kinetic energy burst of the load product.
[0020] In the manufacturing process of this invention, the number of supercapacitors required for series connection is determined based on the evaluation of the voltage range of the battery assembly 1. The battery assembly 1 and the supercapacitor assembly 2 are connected as a whole through a pre-designed circuit adapter board 3. Note that the battery and supercapacitor are not directly connected in parallel on the adapter board 3. Instead, symmetrical copper tubes are welded on the adapter board 3 to lead out the positive and negative terminals of the battery assembly 1 and the supercapacitor assembly 2. The positive and negative terminals of the series-parallel supercapacitor and the battery are designed to be independent, and the positive and negative terminals are not connected to each other. This is to avoid the supercapacitor consuming the battery's power when the composite battery is not in use.
[0021] To enable modular production, the battery assembly 1, the supercapacitor assembly 2, and the adapter plate 3 are all enclosed within the housing 7 (e.g., Figure 3As shown, the battery assembly 1, supercapacitor assembly 2, adapter plate 3, and each positive and negative copper tube are fixed and insulated. The outer casing 7 has through holes 8 corresponding to the positive copper tubes 301, 302, 303, and 304 of the battery assembly, the supercapacitor assembly, and the supercapacitor assembly. After the composite battery is installed in the load product, the positive and negative copper tubes of the battery assembly 1 and the supercapacitor assembly 2 are connected in parallel through the positive and negative copper posts designed for the load product. After parallel connection, the battery will charge the supercapacitor, and then the supercapacitor will provide the product with ultra-high power output capability to realize the high kinetic energy burst of the load product. When not in use, the composite battery is removed, and the positive and negative copper tubes of the battery assembly 1 and the supercapacitor assembly 2 are independent and do not contact each other, which can effectively avoid the supercapacitor consuming battery power.
[0022] The highest continuous discharge capacity of high-rate batteries on the market is generally around 40C (C represents the discharge rate). Front-end equipment ESC manufacturers can support up to 230A or even higher. If the battery capacity is less than 6Ah according to the rate conversion, the discharge rate of 40C is lower than the actual output capacity of the ESC. This composite battery solution can effectively break through the upper limit of battery discharge rate and provide higher kinetic energy output to the load.
[0023] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
