[0034] Please see Figure 1 and Figure 2This utility model provides a battery protection device 100. The battery 201 can be used to supply power and can be used in a data center. The battery protection device 100 is used to protect the battery 201 during the charging and discharging process.
[0035] The battery protection device 100 includes a mounting component 20, and the battery pack 200 includes a plurality of batteries 201, which are respectively mounted on the mounting component 20.
[0036] Mounting component 20 is a mounting rack or mounting cabinet. Mounting component 20 has multiple layers of spaced mounting plates (not shown in the figure), and multiple batteries are placed on each mounting plate.
[0037] Please continue reading Figure 1 and Figure 2 The battery protection device 100 also includes an information processor 10, a circuit breaker 30, and an information acquisition component 40. The circuit breaker 30 is electrically connected to both the battery pack 200 and the information processor 10. The information acquisition component 40 is electrically connected to the information processor 10 and is positioned close to the battery pack 200 to collect the status information of the batteries 201 and send the information to the information processor 10. The information processor 10 calculates and analyzes the collected information and makes a judgment. If it determines that a certain battery 201 in the battery pack 200 is abnormal, it controls the circuit breaker 30 to open, cutting off the circuit and stopping the charging or discharging process of the battery pack 200. Personnel then check the data to identify which battery 201 is abnormal. The information processor 10 incorporates a deep learning algorithm to analyze the information, enabling it not only to determine whether a battery 201 is abnormal but also to issue warnings based on historical information and detect potential risks to the battery 201.
[0038] Specifically, the information processor 10 is connected to the shunt contact of the circuit breaker 30 to control the circuit breaker 30 to open.
[0039] The circuit breaker 30 is mounted on the mounting bracket 20 so that the battery protection device 100 has a compact structure.
[0040] The information acquisition component 40 includes multiple sensors 41. The multiple sensors 41 are disposed on the surface of the battery 201, or on the mounting component 20, or simultaneously disposed on the surface of the battery 201 and the mounting component 20, so as to collect information from the surface of the battery 201 and / or the mounting component 20, so as to allow the information processor 10 to determine whether the battery is abnormal.
[0041] Sensor 41 includes a temperature sensor, a gas sensor, and a smoke sensor, which can determine whether there is an abnormality in the battery 201 from multiple dimensions.
[0042] Temperature sensors are disposed on the surface of the battery 201 and / or on the mounting component 20. Preferably, a temperature sensor is disposed on the surface of each battery 201 and multiple temperature sensors are disposed on the mounting component 20 to monitor the temperature of the surface of each battery 201. This information is used by the information processor 10 to determine whether the circuit breaker 30 needs to be disconnected. It also allows the staff to analyze which battery 201 is abnormal and monitors the temperature of the mounting component 20 to prevent the temperature of the mounting component 20 from becoming too high, which could lead to the temperature of the battery 201 becoming too high.
[0043] The temperature sensor is magnetically attached and can be magnetically attached to the surface of the battery 201 or the mounting part 20, making installation convenient.
[0044] The gas sensor can be a smoke sensor and / or a hydrogen sensor. The gas sensor is mounted on the mounting part 20. The hydrogen detector is used to detect whether the battery is releasing hydrogen due to excessive temperature. The smoke sensor is used to detect whether the battery is releasing smoke due to overcharging, short circuit or improper charging.
[0045] The information acquisition component 40 also includes multiple resistance detectors 42, each corresponding to one of the multiple batteries 201. Each resistance detector 42 is connected to the information processor 10 and placed on the corresponding battery 201 to detect the internal resistance of the battery 201. The information processor 10 can determine whether the internal resistance of the battery 201 is abnormal based on the data from the resistance detectors 42, thereby determining whether the circuit breaker 30 needs to be disconnected. Operators can pinpoint which battery 201 has an abnormal internal resistance based on the data. It should be explained that... Figure 1 In this context, HS refers to Hydrogen Sensor, and R represents Resistance Detector. Figure 2 In this context, T represents a temperature sensor.
[0046] The resistance tester 42 is a non-contact resistance tester. Using a non-contact resistance tester, the health status of the battery 201 can be assessed without interruption, avoiding instability of the uninterrupted power supply system caused by replacing it too early or too late.
[0047] The battery protection device 100 also includes an alarm component 50, which is electrically connected to the information processor 10. The alarm component 50 can issue an alarm after detecting an abnormality in the battery 201 to prevent the accident from spreading.
[0048] The alarm component 50 includes an audible and visual alarm 51, which is installed on the mounting component 20, specifically on the top of the mounting component 20. After an abnormality is detected in the battery 201, the information processor 10 controls the audible and visual alarm 51 to sound an alarm and flash at the same time to remind the staff to handle the situation.
[0049] The alarm component 50 may also include a communication module (not shown), which is located within the information processor 10 and is used to remotely transmit alarm information. After the information processor 10 determines that the battery 201 is abnormal, it promptly sends information to maintenance personnel to prevent the accident from escalating. The communication module may be a wireless communication module, a wired communication module, a Bluetooth communication module, or other communication modules capable of transmitting alarm information to the maintenance personnel's mobile phone or designated terminal.
[0050] The battery protection device 100 also includes a switch box 60, which is mounted on the mounting component 20, and the circuit breaker 30 is located inside the switch box 60.
[0051] Please see Figure 3 The battery protection device 100 also includes a UPS host 70, which is electrically connected to the municipal power supply, the load 300, and the circuit breaker 30. When the municipal power supply fails, the UPS host 70 controls the battery pack 200 to discharge through the switch box 60 to supply power to the load 300; when the municipal power supply is normal, the UPS host 70 controls the battery pack 200 to charge through the switch box 60 to charge the battery 201.
[0052] This utility model also provides an uninterruptible power supply system, including a battery pack 200 and the aforementioned battery protection device 100. The battery pack 200 is connected to the battery protection device 100, and the battery protection device 100 is connected to the load and the municipal power supply. When the municipal power supply is normal, the UPS host 70 converts the AC power from the municipal power supply into DC power and stores it in the battery 201, forming a charging circuit. When the mains power fails, the UPS host 70 converts the DC power from the battery 201 into AC power and supplies power to the load, forming a power supply circuit to achieve uninterrupted power supply.
[0053] This invention collects the status parameters of the battery 201 through an information acquisition component 40 and sends them to an information processor 10. The information processor 10 analyzes the collected data to determine if the battery 201 is abnormal. If abnormal, it disconnects the circuit breaker 30 to stop the charging or discharging of the battery 201. The battery protection device 100 of this invention automatically collects information, which is then analyzed and judged by the information processor 10, achieving automated real-time monitoring. This eliminates the need for manual inspections, saving manpower, and can detect potential problems with the battery 201, providing early warnings and timely detection of safety hazards to prevent accidents such as fires and explosions caused by battery 201 malfunctions.
[0054] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
