Description
Technical Field
The utility model relates to a battery state monitoring technology field, in particular to intelligent battery monitoring early warning system based on multiple type, most sensors.
Background
Since 1799 volts successfully made the first battery in the world, the battery has been rapidly developed, and has been widely used in many aspects such as digital, household electrical appliances, etc. due to its advantages of large specific energy, convenient use, long cycle life, etc. However, the battery itself has a safety hazard that cannot be ignored, and with the emergence of new batteries in recent years, indexes such as battery energy density are increasing to meet the use requirements of people, and the safety problem of the battery is also becoming more acute. Therefore, improving the safety performance of the battery has become an important direction for the development of the battery.
At present, the improvement of the safety performance of the battery is mainly realized by two means of improving the manufacturing technology of a single battery and monitoring the state information of the battery.
Improvement of the battery monomer manufacturing technology, such as addition of electrolyte additives, improvement of the structure of positive and negative electrode materials, and improvement of the preparation process of the diaphragm, is a method for improving the safety of the battery from materials and technologies per se. The method can directly improve the service life and the safety performance of the battery, but the safety performance of the battery is improved by improving the manufacturing process of the single battery, the application cost of the battery is greatly increased, and the method has technical and material barriers and is difficult to meet the increasing safety requirements of the battery of people.
The monitoring of the battery state information is an important means for improving the safety of the battery at present by taking various parameters such as temperature, pressure and the like in the battery runaway process as fault identification parameters and introducing the parameters into the monitoring of the battery state information in consideration of the generation of characteristic gas. Compared with the improvement of the single battery manufacturing technology, the method is low in cost, and some relevant parameters of the battery can be intuitively and effectively obtained, so that the service life and the safety performance of the battery are improved.
The current method for monitoring battery status information has been used for various devices using a battery as a power source, but the following problems still exist:
1) the information type and the number of the monitoring batteries are less: besides the electrical parameters such as voltage, current and internal resistance which are frequently monitored by a battery management system, temperature is generally used as an index for evaluating the safety performance of the battery, and when the battery is out of control, not only the temperature is increased, but also a large amount of gas is generated, so that monitoring the pressure index is an effective means for improving the reliability of a battery monitoring system. In addition, in the current monitoring system, the number of sensors for monitoring the battery state information is large and small, and the sensors are not enough for fully and comprehensively monitoring the state information of the battery, so that more information needs to be monitored, and meanwhile, the information needs to be uploaded to the cloud end and is transmitted to a user after fusion processing, and therefore the reliability of the monitoring system can be improved.
For example, chinese patent CN 205280235U proposes a monitoring structure of a lithium battery temperature sensor, which includes a first lithium battery and a second lithium battery arranged in parallel, a gap is formed between the outer walls of the first lithium battery and the second lithium battery, an adaptive thermal conductive material is filled in the gap, a temperature sensor is embedded in the adaptive thermal conductive material, and the temperature sensor is connected with an external temperature monitoring instrument. The lithium battery has the advantages that the sensing information only has temperature and the number is only one, so that the sensing information is single, and the state performance of the lithium battery is not beneficial to comprehensive evaluation.
It has been realized later that the increased number of sensors will improve the accuracy of the monitoring system, for example, in chinese patent CN 104466285 a, a battery system for electric bicycles is invented, which comprises a battery housing, a battery and a base, wherein a plurality of temperature sensors are arranged inside the battery housing, and a temperature control chip, an alarm lamp, a buzzer and a battery output system are arranged inside the base. The temperature control chip is connected with the temperature sensor, the alarm lamp and the buzzer on one hand, and is connected with the battery output system on the other hand; the battery output system is connected with the battery on one hand and the temperature control chip on the other hand. However, the safety evaluation standard of the battery system is only the temperature parameter, and the parameters such as pressure and gas are not brought into the safety evaluation range, so that the accuracy of the battery monitoring system is not sufficiently improved, and the personal and property safety of a user is not guaranteed.
2) The sensors are not arranged in a number of critical locations of the battery: the sensor arrangement mode of the existing monitoring system is still to be improved, a system taking temperature as a monitoring parameter is taken as an example, most temperature sensors directly measure the surface temperature of the battery, and the biggest problem of the measurement mode is that the internal temperature and the external temperature of the battery have certain temperature difference, the surface temperature of the battery is not enough to reflect the actual temperature state of the battery, so that the phenomenon of thermal runaway already occurs in the battery when the external temperature of the battery is still in a normal range, and finally the monitoring system cannot acquire correct state information. Therefore, sensors need to be arranged at a plurality of key positions of the battery pack/battery, so that the success rate of the lithium battery state information monitoring system is improved.
The placement position of the sensor is also studied, for example, the university of california studies a 18650 cylindrical lithium battery, the structure of which includes two t-type thermocouples installed on the surface of the battery and the battery core, respectively, and based on the two t-type thermocouples, a two-state thermal model of the battery surface and the battery core temperature dynamic state is established, and the safety performance of the lithium battery is evaluated by using signals with the measured surface temperature and the measured battery core temperature. The research proves that the accuracy of evaluating the safety of the battery can be improved practically and effectively by arranging the sensor at the key position of the battery, but the thermocouple used by the structure can monitor the temperature only 15-40 ℃, the measurement temperature range is not enough to cover the temperature of the whole working area of the battery, the monitoring information only has temperature, the information is single, and the early warning and monitoring on the safety performance of the lithium battery during use are not facilitated.
3) Most of the current monitoring systems do not relate to sensing information fusion processing and related algorithms: the method has the problems of insufficient intelligence, insufficient accuracy and the like, and can cause the user to be incapable of accurately and quantitatively evaluating the use state of the battery, so that sensing information fusion processing and related algorithms need to be added into a monitoring system, and the intellectualization of the battery state information monitoring system is improved.
In summary, although the method of monitoring the battery sensing information has achieved certain effects and is already used in the design of some products, the following problems still exist:
1. the type and the quantity of the sensing information are less: in the existing monitoring system, the types of sensors for monitoring the state information of the battery are few, and the sensors are not enough to fully and comprehensively monitor the state information of the battery; in addition, the number of the arranged sensors is insufficient, so that the monitoring accuracy is affected.
2. Sensors are not placed at multiple critical locations of the battery/cell: the sensor arrangement mode of the existing monitoring system is not arranged at a key position, and the accuracy of the monitoring system for evaluating the battery state is influenced.
3. The monitoring system has insufficient intelligence degree: most of the current monitoring systems do not relate to sensing information fusion processing and related algorithms, only transmit data of sensing information to a user, and the data is not processed at all, so that the user cannot quantitatively evaluate the use state of the battery.
Therefore, the above-mentioned deficiencies of the prior art need to be overcome by a new solution, and a battery state monitoring system with various monitoring information, multiple sensor key points, high accuracy and high intelligence degree needs to be researched.
