Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and specifically to an intelligent lithium battery combined with the IOT Internet of Things. Background Technique

[0002] Lithium batteries are a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high requirements for the environment. With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth-generation product of rechargeable batteries, the lithium metal battery, was born in 1996, and its safety, specific capacity, self-discharge rate, and performance-price ratio are all superior to those of lithium-ion batteries;

[0003] In high-power application fields, compared with other types of energy storage batteries, lithium-ion batteries have the advantages of high energy and power density, long cycle life, and environmental protection; compared with nickel-metal hydride batteries, their cell voltage is about 3 times higher, the power density is about 2 times higher, and the self-discharge rate is about 1 / 2, and there is no memory effect. However, in most systems, the reliability of lithium-ion batteries is a bottleneck in their performance. Due to the poor thermal stability and consistency of lithium-ion batteries, the application environment requirements are more stringent, and they cannot be overcharged or over-discharged, and power fluctuations are likely to occur. Secondly, the battery structure has a low level of intelligence during use, and it cannot monitor its real-time status, and cannot give an early warning in the first time when an abnormal situation occurs, resulting in potential safety hazards. Therefore, it is necessary to reasonably and effectively process lithium battery data to ensure battery safety, extend battery life, and improve system performance. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides an intelligent lithium battery combined with the IOT Internet of Things, which solves the problems in the prior art that lithium batteries have more stringent requirements for the application environment, cannot be overcharged or over-discharged, are prone to power fluctuations, have a low level of intelligence, cannot monitor their real-time status, and cannot give an early warning in the first time when an abnormal situation occurs, resulting in potential safety hazards.

[0006] (2) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: An intelligent lithium battery combined with the IOT Internet of Things includes a battery body, a cover plate, a battery management module, and a circuit connection module;

[0008] A protective case is installed at the outer end of the cover plate. A handle is fixedly connected to the middle of the upper part of the protective case. The battery management module is electrically connected to the battery body and the circuit connection module. The other end of the battery management module is electrically connected to a DEGSON connector. A remote charging opening and closing module is installed at one end of the outer side of the protective case. The remote charging opening and closing module is also electrically connected to the battery management module;

[0009] The battery management module includes a Beidou and GPS dual-mode positioning chip, a communication chip, an RFID chip, an NB-IOT chip, and an alarm module. The Beidou and GPS dual-mode positioning chip supports multiple satellite navigation systems and realizes multi-system joint positioning. It supports BDS / GPS / GLONASS multi-system joint positioning and single-system independent positioning. It has active antenna detection and protection, supports all satellites of Beidou-2 / Beidou-3 / No. 1-63 with internal integrated DCDC and LDO. Through GPS and Beidou positioning technologies, users can know the location of the lithium battery anytime and anywhere. In case of emergencies or lost vehicles, it can provide accurate positioning information to facilitate users to take timely measures;

[0010] The communication chip is composed of a control chip, a power management chip, and a communication chip. The control chip controls the charging and discharging process of the battery and monitors the battery status to ensure the safety and long life of the battery. At the same time, the control chip is also responsible for transmitting the battery status information to the battery management system for effective management of the battery. The communication chip mainly controls the data transmission process, including communication protocols and data transmission methods. The communication protocol uses the standard CAN, and the data transmission methods include text, pictures, and audio. The communication chip interacts with an external host to realize the monitoring and control of the battery;

[0011] The RFID chip stores the unique identification code (UID) of the lithium battery. The RFID reader records the operation information during the production of the lithium battery, and the entire production process of the lithium battery can be traced, including the source of raw materials, production time, and production location. This full-chain traceability mechanism helps to quickly locate the source of problems and achieve precise quality control and improvement;

[0012] The NB-IOT chip is based on LTE technology and operates with very low transmission power, providing a longer battery life and a wide coverage range. The NB-IoT chip network can operate on frequencies not used by the existing communication network, reducing interference and providing a good connection.

[0013] Preferably: The NB-IOT chip has a built-in Bluetooth module, which can be Bluetooth-connected to a mobile phone. By downloading an APP, the automatic charging and discharging functions of the lithium battery can be remotely controlled and bound to the user information of the user.

[0014] Preferably, the battery management module further includes a central processing unit, a data acquisition module, a data detection module, a display unit module, and control components (fuse device, relay), and uses internal CAN bus technology to achieve data information communication between modules.

[0015] Preferably, the alarm module uses a gas sensor and an infrared matrix temperature sensor. The gas sensor determines whether the lithium battery starts to fail by detecting abnormal increases in the components of PM2.5 / PM10, TVOCS, and CO2. The infrared matrix temperature sensor is used to detect the temperature change on the surface of the lithium battery to determine whether the lithium battery is abnormal. After the sensor detects an abnormality, it sends the alarm information to the gateway through the standard CAN communication method. The gateway sends the data to the cloud management for remote alarm through the APP to remind the users.

[0017] The present invention provides an intelligent lithium battery combined with the IOT Internet of Things, having the following beneficial effects:

Integrating multiple effects improves the intelligence of the lithium battery. And through the big data management platform, the real-time situation of each group of lithium batteries can be accurately understood. Once an abnormal situation occurs in the backup lithium battery pack, the system will immediately report the abnormal information and notify the operation and maintenance personnel in time for maintenance and replacement, completely solving the problem of active maintenance of the backup power system and greatly reducing the operation and maintenance costs;
