Description

Technical Field

[0001] This invention relates to the field of battery monitoring technology, and more particularly to a battery monitoring device for energy storage stacks. Background Technology

[0002] Energy storage batteries are batteries that convert chemical energy into electrical energy, possessing energy storage capabilities. They store electrical energy during charging and release it when needed to meet electricity demands. Energy storage batteries typically employ rechargeable battery technologies such as lead-acid, nickel-cadmium, nickel-metal hydride, and lithium-ion batteries. Energy storage batteries are a crucial energy storage technology that can improve energy efficiency, promote the application of clean energy, and reduce carbon emissions, playing a vital role in future energy transition and sustainable development. However, during concentrated operation, energy storage batteries may experience abnormal heating and thermal runaway, significantly increasing the probability and severity of accidents. Therefore, real-time monitoring of battery operation is a critical measure for promoting the sustainable development of energy storage technology.

[0003] Currently, most widely used energy storage battery monitoring technologies rely on smoke and heat sensors for detection. During operation, alarms alert staff when an anomaly is detected. However, existing monitoring devices cannot provide comprehensive monitoring of energy storage batteries. Consequently, by the time an anomaly is detected, the battery is often already damaged, leading to economic losses. Summary of the Invention

[0004] This invention discloses a battery monitoring device for energy storage stacks, aiming to address the problem that current widely used energy storage battery monitoring technologies primarily rely on smoke and temperature sensors for detection. During operation, when an anomaly is detected, an alarm system alerts personnel for intervention. However, existing monitoring devices cannot provide comprehensive monitoring of the energy storage battery, often resulting in the battery being damaged before the monitoring device detects an anomaly, leading to economic losses.

[0005] The present invention proposes a battery monitoring device for an energy storage stack, comprising a movable base, a protective cover fixedly connected to one side of the movable base, and a mounting cover plate fixedly connected to one side of the protective cover by bolts. A monitoring component is provided on one side of the movable base, and the monitoring component includes a mounting base. An observation port is provided on one side of the protective cover, and a transparent observation window is fixedly connected inside the observation port. Ventilation ports are provided at equal intervals on one side of the protective cover, and a ventilation filter plate is fixedly connected inside each ventilation port.

[0006] In a preferred embodiment, one side of the movable base is fixedly connected to two limiting rails by bolts, and the two limiting rails are slidably connected to adjusting slides at equal distances inside. Each adjusting slide has a groove on one side, and each groove contains an energy storage battery body. Each energy storage battery body has a push handle fixedly connected to one side.

[0007] In a preferred embodiment, two guide rods are fixedly connected to opposite sides of the protective cover, and movable sleeves are slidably connected to the outside of both guide rods. The same limiting rod is fixedly connected to the opposite side of the two movable sleeves, and a reciprocating drive block is slidably connected to the outside of the limiting rod.

[0008] In a preferred embodiment, an alarm and a temperature sensor are fixedly connected to one side of the reciprocating drive block, and both the alarm and the temperature sensor are located inside the protective cover. A circular hole is provided on one side of the reciprocating drive block, and a rotating shaft is connected to the inside of the circular hole through a bearing. A linkage block is fixedly connected to one side of the rotating shaft.

[0009] In a preferred embodiment, a second circular hole is provided on one side of the mounting cover plate, and a rotating cylinder is connected to the inside of the second circular hole via a bearing. A rotating block is fixedly connected to one side of the rotating cylinder, and a smooth hole is provided on one side of the rotating block. A telescopic adjustment rod is slidably connected inside the smooth hole, and one side of the telescopic adjustment rod is fixedly connected to one side of the linkage block.

[0010] In a preferred embodiment, a drive motor is fixedly connected to one side of the mounting base, and the drive end of the drive motor is connected to one side of the rotating cylinder via a coupling. The same limiting spring is fixedly connected to the opposite side of the linkage block and the rotating block. The limiting spring is located outside the telescopic adjustment rod. Ventilation slots are provided at equal intervals on one side of the movable base.

[0011] By incorporating a monitoring component, the temperature of the energy storage battery during use is monitored by a temperature sensor located above the battery. Simultaneously, a drive motor is activated, causing a rotating cylinder to rotate, which in turn rotates a telescopic adjustment rod. During this rotation, a movable sleeve slides outside a guide rod. When the telescopic adjustment rod rotates to the other side, it moves backward within a rotating block, causing a reciprocating drive block to slide outside a limit rod. This allows the temperature sensor to monitor the battery from all angles. During monitoring, as the battery gradually heats up, operators can pull a push handle to move an adjusting slide within a limit track, separating the battery body on the slide and allowing ventilation slots to dissipate heat. This monitoring component enables comprehensive monitoring of the battery and proactive management of its heat dissipation, preventing damage before abnormalities are detected and minimizing economic losses.

[0012] In a preferred embodiment, the bottom of the movable base is provided with a temperature control component, which includes an air pump. A guide plate is fixedly connected to one side of each of the multiple ventilation slots, and temperature control air holes are equally spaced on one side of each of the multiple guide plates. A hollow temperature control frame is fixedly connected to one side of each of the multiple guide plates.

[0013] In a preferred embodiment, a thermostat is fixedly connected to one side of the protective cover, and the air inlet of the air pump is connected to one end of the thermostat via a pipe, while the air outlet of the air pump is connected to the interior of the hollow thermostat frame via a guide pipe.

[0014] By incorporating a temperature control component, when monitoring the energy storage battery inside the protective cover, if the temperature inside the cover becomes unfavorable for its normal operation, the temperature controller can be activated. An air pump compresses the gas inside the temperature controller into the hollow temperature control frame, allowing the gas to pass through temperature control holes on multiple guide plates to maintain the temperature of the energy storage battery, ensuring it operates at a normal temperature and improving its performance.

[0015] In a preferred embodiment, the movable sleeve is provided with a limiting component inside, and the limiting component includes a telescopic spring, with one side of a plurality of telescopic springs located on the same side being fixedly connected to the same mounting frame.

[0016] In a preferred embodiment, the mounting frames are provided with circular holes three at equal intervals on both sides, and the interiors of two opposite circular holes three on the same mounting frame are connected to rotating shafts via bearings. Each rotating shaft is fixedly connected to an arc-shaped roller, and universal wheels are installed at equal intervals on the bottom of the movable base.

[0017] By setting a limit component, when the movable sleeve moves, the telescopic spring inside the movable sleeve causes the arc-shaped roller to contact the outside of the guide rod through its own telescopic property. As the movable sleeve moves, the arc-shaped roller rotates on its own axis, and the contact area between the arc-shaped roller and the outside of the guide rod is only a point, thereby reducing wear and extending the service life of the monitoring device.

[0018] As can be seen from the above, the battery monitoring device for energy storage stacks provided by the present invention has the beneficial effect of being able to monitor the energy storage battery in all aspects and handle its heat dissipation in advance, avoiding the situation where the energy storage battery has already been damaged when an abnormality is detected, thus reducing certain economic losses.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] This invention discloses a battery monitoring device for energy storage stacks. It primarily addresses the current widespread use of smoke and temperature sensors for monitoring energy storage batteries. During operation, when an anomaly is detected, an alarm system alerts personnel for intervention. However, existing monitoring devices cannot provide comprehensive monitoring of the energy storage battery. Consequently, by the time the monitoring device detects an anomaly, the battery is often already damaged, leading to potential economic losses.

[0023] Reference Figure 1 , Figure 2 and Figure 3 A battery monitoring device for an energy storage stack includes a movable base 1, a protective cover 2 fixedly connected to one side of the movable base 1, and a mounting cover 3 fixedly connected to one side of the protective cover 2 by bolts. A monitoring component 7 is provided on one side of the movable base 1, and the monitoring component 7 includes a mounting base 713. An observation port is opened on one side of the protective cover 2, and a transparent observation window 5 is fixedly connected inside the observation port. Ventilation ports are opened at equal intervals on one side of the protective cover 2, and a ventilation filter plate 4 is fixedly connected inside each ventilation port.

[0024] Reference Figures 1-5Two limiting rails 701 are fixedly connected to one side of the movable base 1 by bolts, and adjustable slides 702 are slidably connected at equal distances inside the two limiting rails 701. Each adjustable slide 702 has a groove on one side, and an energy storage battery body 703 is placed inside each groove. Each energy storage battery body 703 has a push handle 704 fixedly connected to one side.

[0025] Reference Figures 1-5 Two guide rods 710 are fixedly connected to the opposite side of the protective cover 2, and movable sleeves 711 are slidably connected to the outside of the two guide rods 710. The same limiting rod 712 is fixedly connected to the opposite side of the two movable sleeves 711, and a reciprocating drive block 715 is slidably connected to the outside of the limiting rod 712.

[0026] Reference Figures 1-5 An alarm 718 and a temperature sensor 719 are fixedly connected to one side of the reciprocating drive block 715, and both the alarm 718 and the temperature sensor 719 are located inside the protective cover 2. A circular hole is provided on one side of the reciprocating drive block 715, and a rotating shaft 716 is connected to the inside of the circular hole through a bearing. A linkage block 717 is fixedly connected to one side of the rotating shaft 716.

[0027] Reference Figures 1-5 A circular hole 2 is provided on one side of the mounting cover plate 3, and a rotating cylinder 706 is connected inside the circular hole 2 through a bearing. A rotating block 707 is fixedly connected to one side of the rotating cylinder 706. A smooth hole is provided on one side of the rotating block 707, and a telescopic adjustment rod 708 is slidably connected inside the smooth hole. One side of the telescopic adjustment rod 708 is fixedly connected to one side of the linkage block 717.

[0028] Reference Figures 1-5 A drive motor 714 is fixedly connected to one side of the mounting base 713, and the drive end of the drive motor 714 is connected to one side of the rotating cylinder 706 through a coupling. The linkage block 717 and the rotating block 707 are fixedly connected to the same limiting spring 709 on the opposite side. The limiting spring 709 is located outside the telescopic adjustment rod 708. Ventilation slots 705 are provided at equal intervals on one side of the movable base 1.

[0029] In specific application scenarios, during the use of the energy storage battery, the temperature is monitored by a temperature sensor 719 located above the battery. Simultaneously, the drive motor 714 is activated, driving the rotating cylinder 706 to rotate the telescopic adjusting rod 708. During this rotation, the moving sleeve 711 slides outside the guide rod 710. When the telescopic adjusting rod 708 rotates to the other side, it moves backward inside the rotating block 707, causing the reciprocating drive block 715 to slide outside the limiting rod 712. This allows the temperature sensor 719 to move and monitor the energy storage battery from all directions. During the monitoring process, as the energy storage battery gradually heats up, the operator can pull the push handle 704 to move the adjusting slide 702 within the limit track 701. This causes the energy storage battery body 703 on the adjusting slide 702 to separate, allowing the ventilation slot 705 to dissipate heat. The monitoring component 7 can monitor the energy storage battery from all directions and address its heat dissipation in advance, preventing damage when abnormalities are detected and reducing economic losses.

[0030] Reference Figure 1 and Figure 6 The bottom of the mobile base 1 is provided with a constant temperature component 8, which includes an air pump 804. A guide plate 802 is fixedly connected to one side of multiple ventilation slots 705, and constant temperature air holes are opened at equal intervals on one side of multiple guide plates 802. The same hollow constant temperature frame 801 is fixedly connected to one side of multiple guide plates 802.

[0031] Reference Figure 1 and Figure 6 A thermostat 803 is fixedly connected to one side of the protective cover 2, and the air inlet of the air pump 804 is connected to one end of the thermostat 803 through a pipe, and the air outlet of the air pump 804 is connected to the inside of the hollow thermostat frame 801 through an air guide pipe 805.

[0032] In specific application scenarios, when monitoring the energy storage battery inside the protective cover 2, if the temperature inside the protective cover 2 is not conducive to its normal use, the thermostat 803 can be activated. The gas inside the thermostat 803 is compressed into the hollow thermostat frame 801 by the air pump 804. This allows the gas to pass through the thermostat holes on the multiple guide plates 802 to maintain the temperature of the energy storage battery, so that it can be used at a normal temperature, thereby improving its performance.

[0033] Reference Figure 4 and Figure 7The movable sleeve 711 is provided with a limiting component 9 inside, and the limiting component 9 includes a telescopic spring 901. Multiple telescopic springs 901 located on the same side are fixedly connected to the same mounting frame 902 on one side.

[0034] Reference Figure 4 and Figure 7 Multiple mounting frames 902 have round holes 3 at equal intervals on both sides, and the interiors of two opposite round holes 3 on the same mounting frame 902 are connected to rotating shafts 903 by bearings. Each rotating shaft 903 is fixedly connected to an arc-shaped roller 904. Universal wheels 6 are installed at equal intervals on the bottom of the movable base 1.

[0035] In specific application scenarios, when the movable sleeve 711 moves, the telescopic spring 901 located inside the movable sleeve 711 causes the arc-shaped roller 904 to contact the outside of the guide rod 710 through its own telescopic property. As a result, during the movement of the movable sleeve 711, the arc-shaped roller 904 rotates on its own through the rotating shaft 903, and the contact area between the arc-shaped roller 904 and the outside of the guide rod 710 is only a point, thereby reducing wear and tear and extending the service life of the monitoring device.

[0036] Working Principle: During use, the temperature of the energy storage battery is monitored by a temperature sensor 719 located above it. Simultaneously, a drive motor 714 is activated, driving a rotating cylinder 706 to rotate a telescopic adjusting rod 708. This rotation causes the movable sleeve 711 to slide outside the guide rod 710. When the telescopic adjusting rod 708 rotates to the other side, it moves backward within the rotating block 707, causing the reciprocating drive block 715 to slide outside the limiting rod 712. This allows the temperature sensor 719 to monitor the energy storage battery from all angles. During monitoring, as the battery gradually heats up, the operator pulls the push handle 704, causing the adjusting slide 702 to move within the limiting track 701. This separates the battery body 703 on the adjusting slide 702, allowing the ventilation slots 705 to dissipate heat. The monitoring component 7 provides comprehensive monitoring of the energy storage battery. While monitoring the energy storage battery, the device proactively addresses its heat dissipation to prevent damage before any abnormality is detected, thus reducing economic losses. When monitoring the energy storage battery inside the protective cover 2, if the internal temperature becomes unsuitable for normal use, the thermostat 803 can be activated. An air pump 804 compresses the gas inside the thermostat 803 into the hollow thermostat frame 801, allowing the gas to pass through the thermostat holes on multiple guide plates 802 to maintain the battery at a normal temperature, improving its performance. When the movable sleeve 711 moves, the telescopic spring 901 inside it uses its elasticity to make the arc-shaped roller 904 contact the outside of the guide rod 710. During movement, the arc-shaped roller 904 rotates via the rotating shaft 903, with only a single point of contact between the roller 904 and the guide rod 710, reducing wear and extending the lifespan of the monitoring device.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
