Description

Technical Field

[0001] This utility model relates to the field of battery maintenance technology, and in particular to a maintenance system based on remote battery balancing. Background Technology

[0002] Battery maintenance refers to the daily upkeep and periodic inspection of batteries to ensure their proper functioning and extend their lifespan. A battery online maintenance instrument is a high-tech product employing automatic frequency sweep resonance and synchronization interference suppression technology to completely eliminate battery sulfation problems and perform rapid repair and daily maintenance of lead-acid batteries. For users with high power supply reliability requirements, emergency backup power systems such as UPS power supplies, EPS power supplies, high-voltage DC power supplies, DC operating power supplies, and -48V communication power supplies are provided.

[0003] However, existing battery maintenance systems have certain shortcomings in use. Currently, most backup power systems use valve-regulated sealed lead-acid batteries as emergency energy storage devices. Batteries in backup power systems are generally used in series in groups and operate in a long-term online float charging mode. A failure in any single battery can gradually degrade the entire battery pack, or even cause premature shutdown leading to power outages, and may even result in fires or explosions. Therefore, rigorous daily inspection and maintenance of battery packs are essential. Because batteries are not intelligent, unmonitored devices, an online battery monitoring system is necessary for remote, unified monitoring and intelligent maintenance management. Furthermore, the existing integrated battery structure often makes maintenance and replacement difficult, reducing production and maintenance efficiency. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] For examples, please refer to Figure 1-5 This utility model provides a technical solution:

[0025] A maintenance system based on remote battery balancing includes a mounting housing 1. A spring 12 is installed inside the mounting housing 1. One end of the spring 12 is elastically connected to the inner wall of the mounting housing 1, and the other end of the spring 12 is elastically connected to an abutment plate 14. A damping rod 13 is installed inside the spring 12. A positioning groove 15 is formed on the side of the abutment plate 14. A battery structure 7 is set on the side of the positioning groove 15.

A groove 16 is formed on the top of the battery structure 7. A handle 17 is rotatably connected inside the groove 16. A threaded groove 8 is formed on the top of the battery structure 7.

[0026] In this embodiment, as Figure 2 , Figure 4 and Figure 5 As shown, the battery structure 7 includes the battery body and the battery maintenance system. The battery maintenance system includes a battery management system host, a battery online monitoring module, and a display module. The battery management system host is equipped with RS485 and B code time synchronization. The battery online monitoring module uploads data to the host via the R-BUS bus. The display module is a 7 / 10-inch compatible resistive touch screen. The components of the display module are selected from industrial grade. The display module meets the wide operating temperature range requirement of -40℃ to 85℃. The length and width of the battery management system host are set to 274mm and 137mm respectively, and the height of the battery management system host is set to 40mm.

[0027] The battery maintenance system, installed inside the battery structure 7, can monitor various battery data and perform intelligent analysis. It also has an online balancing function, which performs online automatic balancing maintenance of the battery pack in float charging mode and automatically performs voltage-limited low-current compensation charging for undercharged batteries. This ensures that each battery is always in the optimal active state, maintains the voltage balance of the battery pack, and prevents long-term undercharging and sulfation or long-term overcharging and water loss. This can minimize battery failures and extend the battery pack life.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a first bonding plate 2 and a second bonding plate 3 are hinged to the top two sides of the mounting shell 1, respectively. Both the first bonding plate 2 and the second bonding plate 3 are attached to the top of the battery structure 7. A second fixing plate 6 and a first fixing plate 5 are respectively provided on the top of the first bonding plate 2 and the second bonding plate 3. Limiting holes 10 are opened through the sides of the first bonding plate 2 and the second bonding plate 3. Slots 11 are respectively provided on the sides of the first bonding plate 2 and the second bonding plate 3. The second fixing plate 6 is threadedly connected by fixing bolts 4 and threaded grooves 8. The first fixing plate 5 and the second fixing plate 6 are respectively attached to the slots 11. A connecting groove 9 is opened on the top of the mounting shell 1. The first fixing plate 5 is threadedly connected by fixing bolts 4 and connecting groove 9.

[0029] The design incorporates a first bonding plate 2, a second bonding plate 3, a fixing bolt 4, a first fixing plate 5, a second fixing plate 6, a battery structure 7, and a threaded groove 8. This allows for easy disassembly and assembly of the battery structure 7, reducing production assembly and subsequent maintenance time. When maintenance or disassembly of the battery structure 7 is required, simply loosen the fixing bolt 4, then lift the first bonding plate 2 and the second bonding plate 3. The battery structure 7 is then secured inside the mounting shell 1 by spring 12 and abutment plate 14. To remove the battery structure 7, rotate the handle 17 to a vertical position, allowing for easy and quick removal for maintenance. This design ensures the overall stability of the assembled battery structure 7 and provides protection for the battery structure 7. Furthermore, the mounting shell 1 facilitates quick removal of the battery structure 7 should damage occur during subsequent use.

[0030] The working process of this utility model is as follows: When the battery structure 7 needs to be disassembled for maintenance, simply loosen the fixing bolts 4, then lift the first bonding plate 2 and the second bonding plate 3. The battery structure 7 is then fixed inside the mounting shell 1 by springs 12 and abutment plates 14. When the battery structure 7 needs to be removed, turn the handle 17 to make it vertical, and the battery structure 7 can be pulled out for maintenance. This ensures the stability of the battery structure 7 after assembly, and the mounting shell 1 provides protection for the battery structure 7. This design provides protection and facilitates quick removal of the battery structure 7 in case of damage during subsequent use. The battery structure 7 includes the battery body and a battery maintenance system. The battery maintenance system includes a battery management system host, an online battery monitoring module, and a display module. The battery management system host collects data on the voltage, internal resistance, temperature, and connection strip (optional) of individual battery modules and analyzes and processes this data. The online battery monitoring module uses a 2V battery cell acquisition module to monitor the battery's voltage, internal resistance, temperature, and connection strip resistance, and uploads the data to the host via the R-BUS bus. When a battery cell's voltage falls below the average battery voltage threshold, the battery balancing function is activated. Generally, the entire battery pack is adjusted to within the threshold within 2 to 3 months. No adjustment is made during equalization charging and discharging; adjustment is made during float charging. The batteries are connected to an external power supply in parallel. When the individual cell voltage is below the threshold, a control MOSFET is connected to the external power supply for constant current supplementary charging. After 2 minutes of continuous charging (pulse charging), the system re-identifies whether other cells need equalization charging based on a set value, preventing prolonged charging of the same cell.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
