Description

Technical Field

[0001] The utility model relates to the technical field of controllers, in particular to a controller of a modular battery energy storage system. Background Art

[0002] The controller can monitor the status of the modular battery energy storage module in real time, including key parameters such as voltage, current, and temperature. These data can ensure that the modular battery energy storage module operates in a safe and efficient state. The controller can also protect the modular battery energy storage module from overcharging, over-discharging, short circuit and other hazards. When the status of the modular battery energy storage module is abnormal, the controller will take timely measures to prevent battery damage, thereby extending the battery life.

[0003] For example, announcement number CN217279346U discloses a controller for a modular battery energy storage system based on fast Ethernet. The fast Ethernet bus is used to achieve the decoupling of the control computing power expansion and the control quantity capacity expansion of the controller of the modular battery energy storage system. However, the coupling between multiple controllers inside the controller housing is too high, which means that the dependence between the controllers is too close. This close connection will make it extremely difficult to repair and replace a controller when a controller fails, affecting the overall stability and reliability of the controller. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a controller for a modular battery energy storage system. Each controller can be installed and disassembled independently. When one of the controllers fails, the controller can be quickly taken out for replacement and repair, thereby ensuring overall stability and reliability.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a controller of a modular battery energy storage system, comprising a housing, a controller is arranged inside the housing, sliders are fixedly connected at the four corners of the two sides of the controller, thrust springs are connected to the inner bottom walls of the two sliders at the front end, a moving plate is connected to the top of the thrust spring, a card block is fixedly connected to the top of the moving plate, and the top of the card block penetrates and extends to the top of the slider;

[0006] Guide rails are fixedly connected to both sides of the inner wall of the shell, the slider is slidably connected inside the guide rails, a slot is provided at the top of the front end of the guide rail, and the top of the card block is clamped inside the slot.

[0007] Furthermore, the number of the controllers is three, and the three controllers are, from top to bottom, a whole machine controller, a middle layer controller, and a submodule controller.

[0008] Furthermore, sliding rods are fixedly connected to both sides of the slider, sliding holes are opened on both sides of the top of the movable plate, and the outer surface of the sliding rod is slidably connected to the inner side wall of the sliding hole.

[0009] Furthermore, the thrust spring is movably sleeved on the outer surface of the slide rod, the bottom end of the thrust spring abuts against the inner bottom wall of the slide block, and the top end of the thrust spring abuts against the bottom of the moving plate.

[0010] Furthermore, a plurality of heat dissipation grooves are provided on both the front and rear sides of the shell, the interior of the heat dissipation grooves is connected with a fixing ring, and the interior of the fixing ring is fixedly connected with a filter screen.

[0011] Furthermore, a cross rod is fixedly connected to the interior of the heat dissipation groove, and the fixing ring abuts against the outer side of the cross rod.

[0012] Furthermore, a plurality of magnet blocks are embedded in the outer periphery of the fixing ring, and the magnet blocks are adsorbed on the outer shell.

[0013] Furthermore, the side surface of the shell is open, and a side plate is fixedly connected to the side surface of the shell.

[0014] By means of the above technical solution, the utility model provides a controller for a modular battery energy storage system, which has at least the following beneficial effects:

[0015] 1. The controller of the modular battery energy storage system is inserted into the shell, and the slider is inserted into the guide rail. When the slider at the front end slides to the front end of the guide rail, the card block is pushed upward by the thrust spring, so that the top of the card block is stuck in the card slot, thereby fixing and locking the controller; when the controller needs to be removed or moved, the card block is pressed downward to free it from the constraint of the card slot. At this time, the thrust spring is forced to shrink, and the moving plate and the card block will move downward, allowing the slider to slide in the guide rail, and then the controller can be moved or removed from the inside of the shell. Each controller can be installed and disassembled independently. When one of the controllers fails, the controller can be quickly taken out for replacement and maintenance, ensuring the overall stability and reliability.

[0016] 2. The controller of the modular battery energy storage system can dissipate heat inside the shell by convection through the heat dissipation groove, which can effectively reduce the temperature of the controller, ensure that the controller operates within the appropriate temperature range, and improve its stability and reliability. The filter can effectively prevent dust and debris from entering the inside of the shell, keep the inside of the shell clean, and reduce controller failures and performance degradation caused by dust accumulation.

[0017] 3. The controller of the modular battery energy storage system has a fixing ring which is fixed inside the heat sink by a magnet block, so the fixing ring can be easily removed from the outer casing to clean or replace the filter. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 5 A controller for a modular battery energy storage system comprises a housing 1, a controller 2 is arranged inside the housing 1, sliders 4 are fixedly connected to the four corners of the two sides of the controller 2, thrust springs 5 ​​are connected to the inner bottom walls of the two sliders 4 at the front end, a moving plate 6 is connected to the top of the thrust spring 5, a clamping block 7 is fixedly connected to the top of the moving plate 6, and the top of the clamping block 7 penetrates and extends to the top of the slider 4;

[0029] Both sides of the inner wall of the housing 1 are fixedly connected with guide rails 8, and the slider 4 is slidably connected inside the guide rails 8. A slot 9 is provided at the top of the front end of the guide rail 8, and the top of the block 7 is clamped inside the slot 9. The controller 2 is inserted into the housing 1, and the slider 4 is inserted into the guide rail 8. When the slider 4 at the front end slides to the front end of the guide rail 8, the block 7 is pushed upward by the thrust spring 5, so that the top of the block 7 is clamped into the slot 9, thereby fixing and locking the controller 2; when the controller 2 needs to be taken out or moved, the block 7 is pressed downward to break away from the restraint of the slot 9. At this time, the thrust spring 5 is forced to shrink, and the moving plate 6 and the block 7 will move downward, allowing the slider 4 to slide in the guide rail 8, so that the controller 2 can be moved or taken out from the inside of the housing 1. Each controller 2 can be installed and disassembled independently. When one of the controllers 2 fails, the controller 2 can be quickly taken out for replacement and maintenance, ensuring the overall stability and reliability.

[0030] See also Figure 1 and Figure 7 There are three controllers 2, which are a whole machine controller, a middle layer controller and a submodule controller from top to bottom. The whole machine controller is located in the upper layer of the housing 1, the middle layer controller is located in the middle layer of the housing 1 and is connected to the whole machine controller; the submodule controller is located in the lower layer of the housing 1 and is connected to the middle layer controller. The whole machine controller and the middle layer controller together constitute the main controller.

[0031] See also Figure 4 , both sides of the slider 4 are fixedly connected with a slide bar 10, and both sides of the top of the moving plate 6 are provided with a slide hole, and the outer surface of the slide bar 10 is slidably connected with the inner side wall of the slide hole. The thrust spring 5 is movably sleeved on the outer surface of the slide bar 10, the bottom end of the thrust spring 5 abuts against the inner bottom wall of the slider 4, and the top end of the thrust spring 5 abuts against the bottom of the moving plate 6. The cooperation between the slide bar 10 and the slide hole makes the movement of the moving plate 6 more stable without shaking or offset, ensuring that the card block 7 can be accurately inserted into or out of the card slot 9, thereby improving the stability and reliability of the entire locking and unlocking process.

[0032] See also Figure 1 , Figure 2 and Figure 6A plurality of heat dissipation slots 11 are provided on both the front and rear sides of the housing 1. A fixing ring 12 is connected to the interior of the heat dissipation slot 11. A filter 13 is fixedly connected to the interior of the fixing ring 12. A cross bar 15 is fixedly connected to the interior of the heat dissipation slot 11. The fixing ring 12 abuts against the outer side of the cross bar 15. The heat dissipation slots 11 can dissipate the heat inside the housing 1 by convection, which can effectively reduce the temperature of the controller 2, ensure that the controller 2 operates within a suitable temperature range, and improve its stability and reliability. The filter 13 can effectively prevent dust, debris, etc. from entering the interior of the housing 1, keep the interior of the housing 1 clean, and reduce the failure and performance degradation of the controller 2 caused by dust accumulation.

[0033] See also Figure 6 A plurality of magnet blocks 14 are embedded in the outer periphery of the fixing ring 12, and the magnet blocks 14 are adsorbed on the housing 1. Since the fixing ring 12 is fixed inside the heat dissipation groove 11 by the magnet blocks 14, the fixing ring 12 can be easily removed from the housing 1 to clean or replace the filter 13.

[0034] See also Figure 1 and Figure 2 The side of the housing 1 is open, and the side of the housing 1 is fixedly connected with a side plate 3. The design of the side opening makes it easier to install, inspect and replace each controller 2 inside the housing 1.

[0035] Working principle: During installation, the side panel 3 is removed, the controller 2 is inserted into the housing 1, and the slider 4 is inserted into the guide rail 8. When the slider 4 at the front end slides to the front end of the guide rail 8, the block 7 is pushed upward by the thrust spring 5, so that the top of the block 7 is inserted into the slot 9, thereby fixing and locking the controller 2.

[0036] When the controller 2 fails, the card block 7 is pressed downward to release it from the card slot 9. At this time, the thrust spring 5 is forced to shrink, and the moving plate 6 and the card block 7 move downward, allowing the slider 4 to slide in the guide rail 8, so that the controller 2 can be moved or taken out from the housing 1. Each controller 2 can be installed and disassembled independently. When one of the controllers 2 fails, the controller 2 can be quickly taken out for replacement and repair;

[0037] The heat dissipation groove 11 can dissipate the heat inside the shell 1 by convection, which can effectively reduce the temperature of the controller 2, ensure that the controller 2 operates within a suitable temperature range, and improve its stability and reliability. The filter 13 can effectively prevent dust, debris, etc. from entering the interior of the shell 1, keep the interior of the shell 1 clean, and reduce malfunctions and performance degradation of the controller 2 caused by dust accumulation.
