[0029] The present invention provides a storage battery 100 .

[0030] See also Figures 1 to 6 In one embodiment of the present invention, the battery 100 includes: a shell 1, a battery cell and a top cover 2, the shell 1 is formed with a mounting groove 1a; the battery cell is located in the mounting groove 1a; the top cover 2 is detachably connected to the notch of the mounting groove 1a, and the top cover 2 is provided with a monitoring hole 2a and an electrode mounting hole 2b; the battery cell is provided with a monitoring line 3, the monitoring line 3 is passed through the monitoring hole 2a, and the monitoring line 3 is used to output real-time status information of the battery 100.

[0031] In one embodiment, the housing 1 serves as the mounting base for the battery 100. It provides physical protection for the battery's internal components, preventing damage from mechanical impact, vibration, or other external factors. The housing 1 isolates the battery's internal components from the external environment, preventing the intrusion of moisture, dust, and other contaminants, while also preventing electrolyte leakage. V0-rated flame-retardant materials such as ABS (acrylonitrile butadiene styrene) and PC (polycarbonate) offer excellent flame retardancy and impact resistance and are commonly used in the battery 100 housing. The housing 1 material typically has excellent insulating properties, preventing the risk of electrical short circuits or electric shock, as well as the risk of fire. The housing 1 provides stable structural support for the battery, ensuring that the battery maintains its shape and performance under various usage conditions.

[0032] It should be noted that the battery 100 in the present invention is generally a lithium-ion battery or a sodium-ion battery, which is often used in some vehicles or electronic devices, such as electric vehicles, cars, laptops, etc. In electric vehicles or cars, as an energy storage system, a housing 1 with high energy density and high power density is required.

[0033] In one embodiment, a battery cell, also known as a single cell, is the basic unit that makes up the battery 100. Each battery cell has its own electrochemical system that can generate and store electrical energy. Battery cells are combined into battery packs by connecting them in series or in parallel to meet the voltage and capacity requirements of different applications. The battery cell contains a positive electrode, a negative electrode, an electrolyte, and a separator, etc. These components work together to store and convert electrical energy. A single battery cell has a specific voltage. For example, a lead-acid battery cell is typically 2V, and a lithium-ion battery cell is typically 3.7V or higher. The types of battery cells include but are not limited to lead-acid, lithium-ion, sodium-ion, nickel-cadmium (NiCd), nickel-metal hydride (NiMH), etc. Battery cells can be combined into battery packs by connecting them in series (to increase the total voltage) or in parallel (to increase the total capacity). The battery cells need to be managed for charge and discharge by a battery management system (BMS) to prevent problems such as overcharging, over-discharging, and overheating.

[0034] The upper cover 2 is designed with a detachable connection method such as bolts or snaps, which facilitates connection and opening with the notch of the installation slot 1a, simplifying the installation, maintenance and replacement process of the battery. The upper cover 2 is specially provided with a monitoring hole 2a, and the monitoring line 3 is arranged in the monitoring hole 2a. These monitoring lines 3 are used to transmit the real-time status information of the battery cell to the battery management system (BMS). The upper cover 2 is also provided with an electrode mounting hole 2b for connecting the positive and negative poles of the battery cell to ensure the convenience and reliability of the electrical connection. The joint between the upper cover 2 and the outer shell 1 is provided with a sealing ring or rubber ring and other structures. Good sealing must be ensured between the upper cover 2 and the outer shell 1 to prevent moisture, dust and other contaminants from invading the interior of the battery, while avoiding electrolyte leakage. The material selection of the upper cover 2 takes into account mechanical strength, fire resistance, heat resistance, insulation and cost-effectiveness. Commonly used materials include V0-level flame retardant materials such as ABS (acrylonitrile-butadiene-styrene) and PC (polycarbonate).

[0035] The technical solution of the present utility model is a battery 100 comprising a housing 1, battery cells, and a top cover 2. The mounting slots 1a within the housing 1 are designed to allow for installation and removal of battery cells, facilitating battery replacement or upgrades by maintenance personnel. Monitoring holes 2a provided in the top cover 2 allow for the routing of monitoring cables 3, enabling direct connection of the battery management system (BMS) to the battery cells for real-time monitoring of battery status. Monitoring cables 3 output real-time information from the battery 100, such as voltage, current, and temperature, which is crucial for ensuring safe battery operation and optimizing the charging and discharging process. Real-time monitoring allows for timely detection and resolution of battery anomalies, such as overcharging, over-discharging, or overtemperature, thereby mitigating safety risks. The design of the entire battery 100 allows for modular replacement, enabling the replacement of individual cells or battery cells without affecting other cells, thus enhancing maintenance flexibility. The structural design of the housing 1 and top cover 2 provides physical protection for the battery cells, helping to resist external impacts and environmental factors. This type of battery 100 can solve the problem of inconvenient connection between the existing battery 100 and the BMS. In particular, when the battery 100 includes multiple battery packs, the BMS can monitor a single battery pack in the battery 100 in real time, thereby improving the safety, reliability and ease of use of the battery. It is suitable for application scenarios that require high safety and high maintenance efficiency.

[0036] In one embodiment of the present invention, Figures 1 to 3 As shown, the upper cover 2 also includes a fixing part 21, which is detachably connected to the upper cover 2. The fixing part 21 and the upper cover 2 are enclosed to form a wire passing channel 2c. The monitoring line 3 is located in the wire passing channel 2c and is interference fit with the wire passing channel 2c.

[0037] In this embodiment, the upper cover 2 includes a fixing member 21, and the fixing member 21 and the upper cover 2 are connected in a detachable manner, for example, by means of snaps, screws, etc. The design of the fixing member 21 includes a structural feature that cooperates with the upper cover 2 to form a wire-passing channel 2c, and the wire-passing channel 2c is used to guide and protect the monitoring line 3. The monitoring line 3 is arranged inside the wire-passing channel 2c and is interference-fitted with the inner wall of the wire-passing channel 2c, that is, the size of the monitoring line 3 is slightly larger than the inner diameter of the wire-passing channel 2c, thereby forming a close fitting relationship between the monitoring line 3 and the wire-passing channel 2c. This design ensures that the monitoring line 3 can be effectively protected when passing through the upper cover 2 and the fixing member 21 to prevent damage caused by pulling or wear. At the same time, the interference fit also helps to fix the position of the monitoring line 3 to prevent it from shifting during battery operation. The fixing groove 21a on the fixing member 21 interacts with the fixing boss 22 on the upper cover 2, achieving a stable connection between the fixing member 21 and the upper cover 2 through a snap-fitting and position-limiting method, further ensuring the sealing and structural integrity of the cable passage 2c. This structural design not only improves the convenience and reliability of battery assembly, but also enhances the overall performance and durability of the battery system by ensuring the safe transmission of the monitoring cable 3.

[0038] In this embodiment, if Figure 3 and Figure 4 As shown, the fixing member 21 is provided with a fixing groove 21 a, and the upper cover 2 is provided with a fixing boss 22, which is locked and located in the fixing groove 21 a.

[0039] In this embodiment, the fixing member 21 of the battery 100 is designed to include one or more fixing grooves 21a, and the upper cover 2 is correspondingly provided with one or more fixing bosses 22. These bosses are part of the upper cover 2 and are designed to adapt to the shape and size of the fixing grooves 21a. When the fixing member 21 is installed on the upper cover 2, the fixing bosses 22 are inserted and locked into the fixing grooves 21a, ensuring a stable connection between the fixing member 21 and the upper cover 2. This structure not only provides a mechanical locking mechanism to prevent the fixing member 21 from shifting or detaching during battery use, but also facilitates the securement of the monitoring line 3, enabling rapid assembly and disassembly, and facilitating battery maintenance and upgrades.

[0040] In one embodiment of the present invention, Figure 4 As shown, the fixing member 21 is provided with at least two fixing holes 21 b , and the fixing holes 21 b are spaced apart and arranged on both sides of the monitoring line 3 .

[0041] In this embodiment, the fixing member 21 of the battery 100 is designed to have at least two fixing holes 21b, which are evenly spaced on both sides of the monitoring line 3. The size of each fixing hole 21b can be adapted to a corresponding fastener, such as a bolt, screw or rivet, for firmly connecting the fixing member 21 to the upper cover 2. Such a design allows the monitoring line 3 to be positioned at an appropriate position on the fixing member 21 while avoiding excessive pressure or damage to the monitoring line 3, ensuring that the monitoring line 3 can freely transmit the real-time status information of the battery cell to the battery management system (BMS). The design of the fixing hole 21b takes into account the overall structural strength and installation convenience of the battery upper cover 2, while providing convenience for battery maintenance and upgrading, and improving the flexibility and reliability of battery assembly. Through the provision of such fixing holes 21b, stable support and protection of the monitoring line 3 is achieved, thereby enhancing the overall performance and safety of the battery system.

[0042] In one embodiment of the present invention, Figure 3 As shown, waterproof glue is provided between the monitoring line 3 and the monitoring hole 2a, and the monitoring line 3 is bonded to the inner wall of the monitoring hole 2a.

[0043] In one embodiment, in order to ensure that the monitoring line 3 of the battery 100 has good sealing performance when passing through the monitoring hole 2a of the upper cover 2, and to prevent moisture and contaminants from invading the interior of the battery, a special waterproof fixing glue is used between the monitoring line 3 and the monitoring hole 2a to solve problems such as poor wiring contact, while also solving the waterproof problem, with the waterproof level reaching IP67. The waterproof fixing glue is generally epoxy resin potting glue, silicone potting glue, polyurethane potting glue, etc.; the specific implementation method is as follows: first, ensure that the inner wall of the monitoring hole 2a is clean and dry, and then evenly apply a layer of waterproof glue. The waterproof glue should have good bonding properties and chemical corrosion resistance. Next, the appropriate parts of the monitoring line 3 are also coated with waterproof glue to ensure a firm bond. Afterwards, the monitoring line 3 coated with waterproof glue is passed through the monitoring hole 2a so that the monitoring line 3 is tightly bonded to the inner wall of the monitoring hole 2a to form a reliable seal. During the bonding process, the amount of waterproof glue and the curing conditions are controlled to ensure that the sealing performance after bonding meets the design requirements. In addition, the cured waterproof adhesive should also have a certain degree of elasticity to accommodate the slight movement of the monitoring line 3 during operation, further enhancing the sealing effect. This embodiment not only ensures the safety and reliability of the battery, but also simplifies the assembly process and improves production efficiency.

[0044] In one embodiment of the present invention, Figure 3 As shown, an abutting boss 23 is formed on one side of the upper cover 2 facing the mounting groove 1 a , and the abutting boss 23 abuts against the battery unit.

[0045] In this embodiment, the upper cover 2 is provided with an abutment boss 23 facing the side of the mounting slot 1a. The abutment boss 23 extends outward from the inner surface of the upper cover 2, forming a structure that directly contacts the battery cell. The shape and size of the abutment boss 23 closely match the corresponding edge or surface of the battery cell. During assembly, the upper cover 2 is placed and fixed on the notch of the mounting slot 1a. At this time, the abutment boss 23 achieves surface contact or line contact with the contact surface of the battery cell, providing additional support and positioning for the battery cell. This design not only ensures the horizontal and vertical stability of the battery cell within the mounting slot 1a, but also helps to transfer vibration or impact to the battery cell through the abutment boss 23 during battery operation to the upper cover 2 and outer shell 1, reducing potential damage to the battery cell. In addition, the abutment boss 23 also serves as a heat conduction path between the battery cell and the upper cover 2, helping to more effectively dissipate heat generated by the battery during charging and discharging, thereby improving the battery's overall thermal management performance.

[0046] In one embodiment of the present invention, Figure 3 As shown, an abutting rib 11 is formed on the groove wall of the installation groove 1a facing the upper cover 2, and the abutting rib 11 abuts against the battery unit.

[0047] In one embodiment of the present invention, the design of the mounting slot 1a specifically includes a series of abutment ribs 11 formed on the slot wall facing the upper cover 2. These abutment ribs 11 protrude from the slot wall of the mounting slot 1a and are designed to physically contact the periphery or bottom of the battery cell. When the battery pack is installed in the mounting slot 1a, the corresponding parts of the battery cell abut against the abutment ribs 11, providing stable support and positioning for the battery cell. The size, shape, and position of the abutment ribs 11 are optimized based on the specific size and shape of the battery cell to ensure optimal contact between the battery cell and the abutment ribs 11, thereby improving the stability and fixation of the battery cell within the mounting slot 1a. Furthermore, the design of the abutment ribs 11 takes into account the slight deformation that may occur during the battery's charging and discharging process. This ensures that even if the battery volume changes, the abutment ribs 11 maintain effective contact with the battery cell, preventing the battery cell from shifting within the slot. This design not only enhances the mechanical stability of the battery cell but also helps improve the overall structural rigidity of the battery pack, reducing the risk of damage due to physical impact or vibration. Through this structural design, the battery unit is effectively fixed and protected in the mounting groove 1 a , thereby improving the overall performance and reliability of the battery 100 .

[0048] In one embodiment of the present invention, Figure 1 As shown, a waterproof plug 31 is provided at one end of the monitoring line 3 away from the monitoring hole 2a.

[0049] In this embodiment, the monitoring line 3 is designed to include a waterproof plug 31, which is arranged at the end of the monitoring line 3 away from the monitoring hole 2a. Specifically, the side of the monitoring line 3 close to the battery cell is connected to the battery cell, and the side away from the battery cell is equipped with a specially designed waterproof plug 31. The plug is made of waterproof material, such as rubber or silicone, which has good elasticity and sealing properties. During the battery assembly process, the monitoring line 3 is inserted through the monitoring hole 2a of the upper cover 2 and connected to the battery cell, while the waterproof plug 31 is fixed to the outside of the monitoring hole 2a to ensure that when the monitoring line 3 passes through the monitoring hole 2a, the joint between the plug and the hole forms a seal to prevent moisture and contaminants from entering the interior of the battery through the monitoring hole 2a. The structural design of the waterproof plug 31 takes into account the matching with the monitoring hole 2a and the reliability of the connection with the monitoring line 3. It is usually fixed to the monitoring line 3 by means of threads, snaps or bonding. The interior of the plug may contain one or more conductive contacts for connecting to the wires of the monitoring line 3 to ensure the stability of electrical signal transmission.

[0050] The utility model also proposes a battery detection device, such as Figure 6 As shown, the battery testing device includes a battery 100 and a battery management system.

[0051] In an embodiment of the present invention, a battery testing device includes a battery 100 constructed with reference to the above-described embodiment and a battery management system (BMS) operating in conjunction with the device. Based on the received monitoring information, the BMS monitors and manages key parameters of the battery 100, such as voltage, current, and temperature, in real time. It is electrically connected to each cell of the battery 100 via monitoring lines 3, ensuring accurate acquisition of cell status data. The BMS possesses data processing and decision-making capabilities, adjusting charging and discharging strategies based on monitored data, performing balancing control, providing early warning of potential safety issues, and, when necessary, taking protective measures such as disconnecting the circuit or initiating a safety shutdown. Furthermore, the BMS may include a user interface that allows the operator to monitor battery status, receive system alerts, and make necessary configuration adjustments. This design not only improves the safety and reliability of battery use but also optimizes battery performance and service life through precise monitoring and management. It is suitable for a variety of applications requiring precise battery management, such as electric vehicles, energy storage systems, and portable electronic devices.

[0052] In one embodiment of the present invention, Figure 6As shown, a waterproof connector is provided at one end of the battery management system connected to the monitoring line 3.

[0053] In one embodiment, the connection between the battery management system and the monitoring line 3 utilizes a waterproof connector. One end of the monitoring line 3 is fitted with a waterproof plug 31, made from a high-grade waterproof material such as silicone rubber or a specially formulated plastic, ensuring excellent waterproof sealing properties. A waterproof connector that mates with the waterproof plug 31 is located at the corresponding port of the battery management system. The socket is designed with a sealing ring or similar sealing mechanism. When the waterproof plug 31 is inserted into the waterproof connector, the two seal together, preventing moisture from entering the battery management system.
