Description

Technical Field

[0001] The invention relates to an EMS control board, in particular to an EMS control board of a base station energy storage system. Background Art

[0002] The Energy Management System (EMS) is the core component of the power energy storage system, responsible for real-time monitoring and precise control of the entire energy storage system to ensure safe and stable operation of the system. As the key hardware of EMS, the performance of the EMS control board directly affects the operation quality of the entire energy storage system.

[0003] Existing EMS control boards usually have the following extensions based on the basic voltage sensor, current sensor, and power sensor: 1. Add temperature sensors to monitor internal temperature and ensure safe and stable operation of the system.

[0004] 2. Add gas sensors to monitor the gas composition and concentration around the system, such as carbon monoxide concentration; by monitoring the gas environment around the system, potential safety hazards can be discovered in a timely manner; in the event of a malfunction or accident, the leakage of harmful gases can be detected and emergency measures can be triggered.

[0005] 3. Add humidity sensors to monitor the humidity level of the system environment. Too high or too low humidity may have an adverse effect on the operation of power equipment, such as reduced insulation of equipment and metal corrosion. If abnormal humidity is detected in time, measures can be taken in time to avoid equipment damage or insulation performance degradation and other faults.

[0006] However, existing EMS control boards directly adopt a fixed design with integrated temperature sensors, gas sensors and humidity sensors.

[0022] 6. In the present invention, when it is necessary to control the two inner locking blocks to move inward to disengage from the corresponding inner locking concave surfaces to release the lock of the contact block, it is only necessary to control the two execution shafts to move upward. After the two execution shafts move upward, they can respectively push the two return push blocks to move inward, so that the two inner locking blocks can follow the inward movement and hide in the horizontal stroke holes; it has the advantage of convenient unlocking method.

[0023] 7.

[0040] The working principle of this embodiment is: In order to facilitate the user's manual operation, a touch screen connected to the controller will be configured.

[0041] In a default state, each of the first electrically-controlled valves 811 and each of the second electrically-controlled valves 812 are in a closed state.

[0042] The process of installing any detachable sub-circuit board 20: 1. Turn on the air pump 91 and the corresponding first and second electrically controlled valves 811 and 812 through the touch screen. The air pump 91 will supply air to the first electrically controlled valve 811. The air will then enter the two first air supply ports 61 through the conduit, and then enter the two execution cavities 51, and then provide an upward force for the two execution shafts 52. After the two execution shafts 52 move upward, they will push the two return push blocks 45 inward respectively, so that the two inner locking blocks 431 can follow the inward movement and hide in the horizontal stroke hole 421, so that the movable execution seat 42 can smoothly contact the bottom surface of the inner groove 2011.

[0043] 2. The air pump 91 will supply air to the second electric control valve 812 at the same time. The air will then enter the second air supply port 75 through the conduit, and then enter the driving inner cavity 72, and then provide an upward force for the driving shaft 64, driving the shaft 64 to move upward until the movable anti-slip block 731 and the fixed anti-slip block 732 abut against each other and stop; at this time, the movable actuator seat 42 moves up and is in the highest position.

[0044] 3. Place the detachable sub-circuit board 20 into the corresponding placement hole 31 until the movable execution seat 42 contacts the bottom surface of the inner groove 2011 and stops; at this time, each conductive pin 321 will be located just above each conductive seat 322 and has not been inserted into each conductive seat 322.

[0045] 4. First, close the second electrically controlled valve 812 to prevent leakage of air in the inner cavity 72; then close the air pump 91, and the two inner locking blocks 431 will move outward under the outward force provided by the first spring 44, and the air in the inner cavity 51 will be pressed out; after the two inner locking blocks 431 move outward, they will be pushed into the two inner locking concave surfaces 432 respectively, so as to lock the contact block 201.

[0046] 5. Open the second electric control valve 812 again, and the movable actuator seat 42 moves downward under the downward force provided by the tension spring 63 to perform a pull-down operation, so that each conductive needle 321 can be inserted into each conductive seat 322 respectively, so that the corresponding detachable sub-circuit board 20 and the EMS control board body 14 form an electrical plug-in.

[0047] It should be noted that in order to simplify the operation steps, the programming control of the controller is: The first step is to open the air pump 91 and the corresponding first electrically controlled valve 811 and second electrically controlled valve 812; Step 2: After closing the second electrically controlled valve 812 and the air pump 91, wait for 2 seconds and then automatically close the second electrically controlled valve 812.

[0048] The installation of the corresponding detachable sub-circuit board 20 can be completed by simply pressing two steps on the corresponding screen on the controller, which is very convenient.

[0049] The process of removing any detachable sub-circuit board 20 is as follows: 1. Turn on the air pump 91, the second electric control valve 812 and the first electric control valve 811 through the touch screen. The air pump 91 will supply air to the second electric control valve 812. The air will then enter the second air supply port 75 through the conduit, and then enter the driving inner cavity 72, and then provide upward force for the driving shaft 64, driving the shaft 64 to move upward until the movable anti-slip block 731 and the fixed anti-slip block 732 abut against each other and stop. At this time, the movable actuator seat 42 moves up and is at the highest position.

[0050] 2. As the movable execution seat 42 moves upward, each conductive needle 321 will be automatically separated from each conductive seat 322.

[0051] 3. The air pump 91 will supply air to the first electric control valve 811 at the same time. The air will then enter the two first air supply ports 61 through the conduits, and then enter the two execution cavities 51, and then provide upward force for the two execution shafts 52. After the two execution shafts 52 move upward, they will push the two return push blocks 45 inward respectively, so that the two inner locking blocks 431 can follow the inward movement and hide in the horizontal stroke hole 421.
