Description

Technical Field

[0001] This invention belongs to the field of battery technology, specifically relating to a nickel-metal hydride battery module structure. Background Technology

[0002] In recent years, with the accelerated construction of new energy systems, electrochemical energy storage technology has experienced explosive growth, with a wide variety of technological approaches emerging. Among them, nickel-metal hydride (NiMH) batteries, as a new type of energy storage battery, have advantages such as long cycle life, no risk of fire or thermal runaway, flexible charging and discharging speeds, no need for routine maintenance, good performance at high and low temperatures, low cost, no toxic substances, and 100% recyclability. They can be applied to energy storage scenarios such as renewable energy distribution and storage, grid peak shaving and frequency regulation services, and building-integrated energy storage, and are particularly suitable for long-term energy storage, showing broad prospects and becoming a "hotspot" industry in the new energy field. Currently, cylindrical NiMH batteries are commonly used in the market, but the voltage and current provided by a single NiMH battery are relatively limited, sometimes unable to meet the requirements of high current or high voltage applications. Therefore, there is an urgent need to design a NiMH battery module structure. Summary of the Invention

[0004] A nickel-metal hydride battery module structure includes a base, a bracket, and a plurality of nickel-metal hydride batteries. The bracket is fixedly connected to the top of the base. The bracket is provided with fixing holes corresponding to the number of nickel-metal hydride batteries. The nickel-metal hydride batteries are installed one-to-one in the corresponding fixing holes. Each nickel-metal hydride battery is provided with a positive electrode tab and a negative electrode tab at its top.

[0005] Furthermore, the bracket includes two parallel side plates, the bottom ends of both side plates are fixedly connected to the base, and the top ends of both side plates are fixedly connected to a top plate. The fixing hole is opened on the top plate, and the nickel-metal hydride battery is installed in the fixing hole.

[0006] Furthermore, a plurality of the fixing holes are arranged in a rectangular array on the top plate.

[0007] Furthermore, a retaining ring is fixedly connected to the upper sidewall of the nickel-metal hydride battery, and the retaining ring is fixedly connected to the upper surface of the top plate.

[0008] Furthermore, the distance from the retaining ring to the bottom of the nickel-metal hydride battery is less than the distance from the top plate to the upper surface of the base.

[0009] Furthermore, the fixing hole is a square hole, the side length of the fixing hole is greater than the diameter of the nickel-metal hydride battery, and the outer diameter of the retaining ring is greater than the side length of the fixing hole.

[0010] Furthermore, the fixing hole is a circular hole, the diameter of the fixing hole is larger than the diameter of the nickel-metal hydride battery, and the outer diameter of the retaining ring is larger than the diameter of the fixing hole.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] In this invention, a bracket with fixing holes can be set to arrange several nickel-metal hydride batteries in an orderly array. Then, by connecting several nickel-metal hydride batteries in series or in parallel, they can be used to meet the requirements of high voltage or high current. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1

[0020] Reference Figure 1-3 A nickel-metal hydride (NiMH) battery module structure includes a base 1, a support 2, and several NiMH batteries 4. The support 2 is fixedly connected to the top of the base 1. The support 2 has mounting holes 3 corresponding to the number of NiMH batteries 4. Each NiMH battery 4 is installed one-to-one in its corresponding mounting hole 3. Each NiMH battery 4 has a positive electrode tab 6 and a negative electrode tab 7 at its top. In actual use, the NiMH batteries 4 can be connected in series or in parallel as needed. When connected in series, the output voltage can be increased; when connected in parallel, the output current can be increased.

[0021] In this embodiment, the bracket 2 includes two parallel side plates 21. Both side plates 21 are vertically arranged and their bottom ends are fixedly connected to the base 1. The top ends of both side plates 21 are fixedly connected to a top plate 22. Fixing holes 3 are opened on the top plate 22, and nickel-metal hydride batteries 4 are installed in the fixing holes 3.

[0022] In this embodiment, a number of fixing holes 3 are arranged in a rectangular array on the top plate 22.

[0023] In this embodiment, a retaining ring 5 is fixedly connected to the upper sidewall of the nickel-metal hydride battery 4, and the retaining ring 5 is fixedly connected to the upper surface of the top plate 22. Specifically, the retaining ring 5 and the top plate 22 can be bonded together with adhesive.

[0024] In this embodiment, the distance from the retaining ring 5 to the bottom of the nickel-metal hydride battery 4 is less than the distance from the top plate 22 to the upper surface of the base 1. This allows the nickel-metal hydride battery 4 to be suspended relative to the base 1 after it is installed in the fixing hole 3 through the retaining ring 5. This not only avoids collisions but also improves heat dissipation.

[0025] In this embodiment, the fixing hole 3 is a square hole, and the side length of the fixing hole 3 is greater than the diameter of the nickel-metal hydride battery 4, so that the nickel-metal hydride battery 4 can be easily installed in the fixing hole 3. The outer diameter of the retaining ring 5 is greater than the side length of the fixing hole 3.

[0026] Example 2

[0027] Reference Figure 4 The technical solution of this embodiment is basically the same as that of embodiment 1. The only difference is that the fixing hole 3 in this embodiment is a circular hole, the diameter of the fixing hole 3 is larger than the diameter of the nickel-metal hydride battery 4, and the outer diameter of the retaining ring 5 is larger than the diameter of the fixing hole 3.

[0028] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
