Description

[Technical field]

[0001] The utility model relates to the technical field of lithium battery storage, and in particular to an intelligent lithium battery safety storage system. [Background technology]

[0002] Lithium is an active metal. The energy density of lithium batteries is much higher than other types of batteries. They are widely used in various fields of human production and life, such as new energy vehicles, mobile phones, laptops and robots. Lithium batteries usually use flammable organic solvents as electrolytes. Once thermal runaway occurs, a large amount of heat will be released rapidly, causing fire or explosion. Lithium battery storage is an important issue in the lithium battery safety management chain.

[0003] At present, lithium battery storage is usually achieved by setting up special warehouses with video surveillance and fire-fighting facilities to monitor and extinguish fires. However, due to the large storage space of warehouses for large quantities of batteries and the fact that lithium batteries catch fire from the inside out, it is difficult for fire extinguishing agents to enter the batteries to extinguish the fire.

[0004] The lithium battery storage method in the prior art has the following problems:

[0005] 1. Large quantity and large space storage. Usually a battery warehouse stores tens of thousands or even hundreds of thousands of lithium batteries. Once thermal runaway occurs in one of the lithium batteries, it is very easy to cause the entire battery warehouse to catch fire and explode.

[0006] 2. It is difficult to detect abnormalities in the early stage of thermal runaway of lithium batteries, and the precious opportunity to extinguish the fire is missed.

[0007] 3. It takes a long time from discovering the thermal runaway anomaly of the lithium battery to taking measures to extinguish the fire.

[0008] 4. The effective fire extinguishing method currently used is to spray water or fire extinguishing agent on the lithium battery, but the fire extinguishing effect is not good.

[0009] 5. The fire extinguishing target is poorly directed, and a large number of intact lithium batteries are damaged during the fire extinguishing process.

[0010] 6. A large number of lithium batteries are prone to explosion after thermal runaway, posing a serious threat to the life and health safety of firefighters.

[0011] 7. After a fire in a lithium battery warehouse, a large amount of sewage generated during the fire extinguishing process will cause environmental pollution. [Contents of the utility model]

[0027] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] See also Figure 1 The intelligent lithium battery safety storage system of the utility model includes a plurality of independently arranged storage units 10 and an MCU control center 20. The storage unit 10 includes a storage matrix, in which a plurality of lithium batteries 17 are stored. The size, structure and style of the storage matrix can be designed according to actual needs. Generally, the size of the storage matrix is ​​determined according to the shape and size of the lithium battery 17 and the number stored in the storage unit 10. The number of storage units 10 can be determined according to the number of lithium batteries 17 stored.

[0029] The storage base is provided with a temperature sensor 11 , a smoke sensor 12 and an infrared sensor 13 , and the temperature sensor 11 , the smoke sensor 12 and the infrared sensor 13 are respectively connected to the MCU control center 20 .

[0030] A water inlet pipe 15 is connected to one side of the storage base, and the water inlet pipe 15 is connected to the inside of the storage base. A solenoid valve 16 is arranged on the water inlet pipe 15, and the solenoid valve 16 is connected to the MCU control center 20. The solenoid valve 16 is used to control the on and off of the water inlet pipe 15. The water inlet pipe 15 can be arranged at the bottom of the side wall of the storage base. When extinguishing a fire, water soaks from bottom to top. When the water submerges the fire point, the water injection can be stopped to reduce the number of lithium batteries 17 soaked and reduce losses.

[0031] A window 14 is provided on one side of the storage base, and the window 14 can be used as an overflow port or an explosion vent. The height of the window 14 is higher than the placement height of the lithium battery 17 to prevent water from soaking into the fire point during fire extinguishing.

[0032] A flame retardant layer may be provided inside the storage base, which is helpful in blocking the spread of fire and reducing losses once a fire occurs.

[0033] The intelligent lithium battery safety storage system includes a remote monitoring room 30, the MCU control center 20 is connected to the remote monitoring room 30, and sound and light alarms are provided in the remote monitoring room 30 and in the storage base, and the sound and light alarms are connected to the MCU control center 20. The remote monitoring room 30 can realize 24-hour remote monitoring, so that the lithium battery storage status information can be delivered to the storage management personnel in time.

[0034] A monitoring screen is also provided in the remote monitoring room 30 , and the monitoring screen is connected to the MCU control center 20 .

[0035] The MCU control center 20 is connected to a power module 40, and the power module 40 supplies power to the MCU control center 20. The power module 40 is a 220V, 12V AC to DC power module.

[0036] The temperature sensor 11, the smoke sensor 12, and the infrared sensor 13 are used to monitor the temperature and smoke status in the storage unit 10, as well as the thermal status of the lithium battery 17 in real time;

[0037] The MCU control center 20 receives the monitoring data of the temperature sensor 11, the smoke sensor 12, and the infrared sensor 13 in real time. When the infrared sensor 13 detects that the thermal state of a lithium battery 17 in the storage unit 10 is abnormal, the MCU control center 20 immediately controls the sound and light alarm in the storage unit 10 to sound an alarm, and transmits the abnormal information to the remote monitoring room 30. The remote monitoring room 30 confirms the abnormality and sounds a sound and light alarm, and displays the abnormal information on the monitoring screen, and notifies the warehouse management personnel of the location and abnormal situation of the abnormal battery;

[0038] When the temperature sensor 11, the smoke sensor 12, and the infrared sensor 13 simultaneously detect abnormal signals, the MCU control center 20 confirms that it is a fire, and immediately controls the sound and light alarm in the storage unit 10 to sound an alarm, and at the same time controls the solenoid valve 16 to open the water switch to inject water into the storage unit 10 for fire extinguishing, and at the same time transmits the abnormal information to the remote monitoring room 30. The remote monitoring room 30 confirms the fire and sounds an sound and light alarm, and at the same time displays the fire information on the monitoring screen, and notifies the warehouse manager of the fire location and situation. After receiving the fire information, the warehouse manager should go to the corresponding storage unit 10 in time to deal with it.

[0039] When the water level in the storage unit 10 reaches a certain level, excess water overflows from the overflow port. In extreme cases, the lithium battery 17 in the storage unit 10 may explode and rupture, and the overflow port can vent the explosion, so the overflow port is also an explosion vent.
