Description
Technical Field
The utility model relates to the field of safety monitoring of energy storage batteries, in particular to a safety monitoring module applied to thermal runaway of an energy storage battery.
Background
With the advent of the electrified era, the electric equipment is increasingly used, the use frequency is also higher, the use scene is also wider, the electric equipment is not only applied to the scene with a fixed power supply, but also applied to the field, and even used along with vehicles such as automobiles, airplanes, ships and the like, the movable energy storage battery is also widely applied along with the movable energy storage battery to solve the field power consumption requirement.
The biggest disadvantage of energy storage batteries is that thermal runaway during charge and discharge causes fire, even explosion, and causes loss of personal and property. In real life, the thermal runaway event of the energy storage battery frequently happens, and once the thermal runaway event happens, the thermal runaway event is difficult to extinguish, and the thermal runaway event can be completely burnt out. The most effective safety measure for energy storage cells is thus protection against unburned fuel.
The thermal runaway process of the energy storage battery is that firstly, the temperature of the battery is increased, then the internal pressure is increased, and then the concentration of carbon monoxide, hydrogen, methane, smoke and the like around the battery are increased, and finally, the battery fires and burns, or even explodes.
The existing energy storage thermal runaway monitoring technology mainly adopts monitoring devices with single parameters, such as a VOC gas sensor, a temperature sensor, a current/voltage sensor and a gas pressure sensor. The sensors can measure the VOC gas concentration in real time and send out an alarm when a preset threshold value is reached, so as to remind operators of carrying out corresponding treatment. The temperature sensor can monitor the change of the system temperature and detect whether overheat exists. The pressure sensor can detect the change of the gas pressure in the system and is used for finding out the problems of gas leakage and the like. The prior art has some limitations in the safety monitoring of energy storage systems. Thermal runaway of batteries is a complex multi-parameter problem that involves the interplay of multiple parameters of temperature, current, gas, etc. The sensors in the existing schemes can only monitor a few parameters, and the correlation among the parameters cannot be completely comprehensively analyzed, so that the understanding of the whole situation is incomplete. Conventional VOC gas sensors, temperature sensors and pressure sensors typically need to be used alone, and integrated monitoring of multiple parameters cannot be achieved.
The closest prior art with this application technical scheme is the multi-parameter monitoring device to energy storage system safety monitoring. The device integrates various sensors, including VOC gas sensor, temperature sensor, pressure sensor, current and voltage sensor, etc., and can realize real-time monitoring of various safety characteristic parameters of the energy storage system. However, these prior art techniques have yet to be improved in terms of data acquisition and analysis, lack the ability to quickly and accurately monitor and pre-warn of energy storage systems, and are not capable of meeting the need for quick acquisition and accurate analysis of energy storage system safety feature parameters. Most of the monitoring technologies monitor middle and late phases of thermal runaway, early warning cannot be obtained, and therefore measures cannot be taken in time to prevent or cope with the problem of thermal runaway of the battery. And, battery thermal runaway monitoring involves different types of batteries and application scenarios. Existing solutions have limitations in their ability to accommodate different battery types and operating conditions and do not provide a versatile solution.
While some energy storage system safety monitoring techniques and devices already exist, the prior art has certain limitations in multi-parameter integrated monitoring, data acquisition and real-time analysis.
Under the background, there is a need in the market for a monitoring module in an energy storage battery, which uses a sensor integrated monitoring module and a central processing unit to collect the data changes of the parameters in real time, and provide key data information for the safe operation of the energy storage battery, and monitor and control the operation state of the energy storage battery in real time. Through real-time supervision and various parameters of analysis, the monitoring module can discover potential problem and trouble in advance, ensures energy storage battery's safe operation. The rapid acquisition and accurate analysis of the data are helpful for timely taking measures, avoiding thermal runaway safety accidents of the energy storage battery, ensuring the performance and reliability of the energy storage battery, protecting the safety of personnel and property, and promoting the sustainable development of the energy storage technology.
