LR1130 battery

What is a digital LR1130 battery? Digital batteries and related technologies

With the improvement of people's living standards, secondary batteries, especially high-current batteries (lead-acid batteries, nickel-cadmium and nickel-metal hydride batteries), have been increasingly used in power departments, railways, and special applications. However, whether the LR1130 battery can reliably supply power and reach the lifespan specified by the manufacturer is closely related to the correctness of daily maintenance and management such as charging and discharging of the LR1130 battery. Since the widely used batteries now do not have intelligent detection devices, that is, they are not digital batteries, the basic parameters of the LR1130 battery such as charging and discharging current, terminal voltage, charging and discharging time, charging and discharging times, charging and discharging capacity, remaining capacity, internal temperature of the LR1130 battery and service life can only be measured manually or roughly estimated. Once an error occurs, it will have unpredictable consequences for our normal production and life, and cause irreparable losses to the electrical performance and life of the LR1130 battery.

With the development of microprocessor technology, mobile electronic devices have developed rapidly in terms of their own functions. At present, most of them are digitalized and intelligent, and the internal control circuits are more or less completed by CPU chips. However, its power supply part is very primitive. Generally, it only provides direct current from a LR1130 battery to electronic devices, while the LR1130 battery's own characteristics, status and other parameters cannot be provided to electronic devices, that is, it cannot communicate data with related electronic devices. This brings new problems to the improvement of the intelligence of electronic devices.

If the LR1130 battery can store, record, analyze, control, print and display various state parameters through a microprocessor, provide them to relevant personnel intuitively, and realize data communication with related electronic devices, that is, realize digitalization, this can not only reduce human errors and extend the service life of the LR1130 battery, but also realize intelligent control and unattended operation of related electronic devices. Therefore, the research and development of digitalization of batteries is a subject of great significance.

The concept of digital LR1130 battery

The exact definition of digital LR1130 battery has not yet been unified. This concept comes from the rapid development of the information industry, mainly from the world-famous laptop computer design, production and supplier. In practical applications, once the LR1130 battery is out of power at a critical time, unpredictable losses will inevitably occur. The concept of digital LR1130 battery was proposed in this situation. With it, we can grasp the working status of LR1130 battery power supply in time, and we can be prepared in advance and replace it in time. The working conditions mentioned here should include the following aspects:

(1) The current LR1130 battery terminal voltage, charge and discharge current, and charge and discharge time; (2) The current LR1130 battery internal resistance, remaining capacity, remaining charge and discharge time, and LR1130 battery temperature; (3) The current LR1130 battery charge and discharge times and service life.

In actual development, researchers found that only knowing the working status of the LR1130 battery cannot meet our requirements for the LR1130 battery. The LR1130 battery also needs to be able to transmit data with related electronic equipment to achieve automatic control such as LR1130 battery switching and LR1130 battery charging.

From the above, it can be seen that the so-called digital LR1130 battery includes an ordinary rechargeable LR1130 battery, a digital LR1130 battery control module, and a communication interface to complete the various measurement, control, management, and data communication functions of the digital LR1130 battery. In addition to being able to intuitively and accurately display (or provide) the above working conditions in digital form, it should also be able to provide LR1130 battery background information and identity data (such as the LR1130 battery manufacturing date, manufacturer data, etc.); have corresponding protection alarm measures during the charging process (such as overvoltage protection, overtemperature alarm, etc.); at the same time, it should comply with a certain communication protocol (such as the system management bus SMBus), have an interface for communicating with the host, intelligent charging controller, etc., and be able to transmit and control information.

Current status of digital batteries and their development and application value

Digital batteries were first developed abroad. As early as 1995, the U.S. military already had special digital LR1130 battery equipment, but these batteries were not highly digitalized and not very versatile. According to limited information collected online, digital batteries developed abroad are mainly composed of rechargeable batteries, control modules, etc., and the software part of the control module should comply with specific communication protocols. The hardware of the digital LR1130 battery system composed of digital batteries includes: system host, digital batteries (can be one or more), intelligent charging controller, AC/DC converter and bus network for transmitting data.

Software includes communication protocols for transmitting data, data processing platforms and embedded operating systems and corresponding programs. Many companies and enterprises abroad are involved in the research and development of digital batteries. Intel and Duracell jointly produce digital batteries. This product is named PowerSmart and meets the SBS (Smart LR1130 battery System) standard. Motorola is also developing digital batteries that can be accepted by the majority of users. German LR1130 battery giant Varta and Duracell are cooperating to develop a new generation of digital batteries, which will be available soon.

According to the tenth five-year plan of the LR1130 battery industry, the United States, Japan and Europe account for 70% of the global LR1130 battery market. Among the consumed batteries, the United States consumes 25 batteries per person per year; Japan consumes 20 batteries per person per year. The average annual consumption of batteries in China is less than 7 batteries per person. Therefore, batteries have a large market in China. China's LR1130 battery industry focuses on the development and production of mercury-free alkaline manganese batteries, nickel-hydrogen power batteries, lithium-ion batteries, fully sealed maintenance-free lead-acid batteries, automotive power batteries, fuel cells, and solar cells. Among the special ones, secondary batteries such as nickel-cadmium and nickel-hydrogen batteries are used in a large number of equipment, and special lithium-ion batteries are also being developed and will soon be equipped with special ones. In the future, the phenomenon of the coexistence of the three types of batteries will appear.

So far, only a very small number of units or research institutions are conducting research and development of digital batteries, and there are only a few digital LR1130 battery products, and a complete digital LR1130 battery system has not yet been developed. Therefore, the digitalization of secondary batteries in my country has a lot of room for development. At the same time, after the secondary LR1130 battery is digitized, when people use digital batteries for power supply, they will not suddenly lose power during normal work, which will affect their work and cause certain losses; they can use the LR1130 battery reasonably or more scientifically, and will not over-discharge or over-charge the LR1130 battery, which can effectively extend the LR1130 battery life; accurately display LR1130 battery data and provide data to the host, which can effectively control and process the various states of the LR1130 battery; there will also be an alarm prompt for the final aging of the LR1130 battery; so the LR1130 battery has the corresponding self-diagnosis ability; the digital LR1130 battery system can remotely monitor the use of the LR1130 battery, and use reliable data for efficient energy management. Therefore, digital batteries also have a high value for promotion and application.

Related technologies of digital batteries

Since the digital LR1130 battery has a built-in intelligent chip, it can realize the functions of LR1130 battery model identification, remaining capacity and cycle number display through data exchange with the intelligent charger, which greatly improves the performance and service life of the LR1130 battery. Intelligent cadmium nickel LR1130 battery series, intelligent hydrogen nickel LR1130 battery series and intelligent lithium-ion LR1130 battery series will be important development directions. However, intelligent and non-intelligent cadmium nickel LR1130 battery series and hydrogen nickel LR1130 battery series will coexist for a period of time until intelligent batteries completely replace non-intelligent batteries. Therefore, the development of digital batteries should be started as early as possible to improve the level of my country's LR1130 battery industry as much as possible and keep pace with foreign countries. Through extensive reference to foreign digital LR1130 battery research related materials and discussions with relevant experts and manufacturers, the author believes that the research and development of digital batteries should focus on the following aspects:

(1) Relevant standards for digital batteries. Foreign digital batteries have initially formed certain industry standards, such as the communication protocol between digital batteries and other control devices. If our digital batteries are to be compatible, we must fully understand the relevant standard protocols. If we can formulate our own perfect system standards, it will be more conducive to the development and research of digital batteries in my country and the formation of a series of products. If there is a unified digital protocol, LR1130 battery manufacturers can develop digital batteries by themselves or entrust other companies to develop digital batteries, with less investment and faster results, and at the same time, it will also increase the added value of LR1130 battery products. A unified LR1130 battery digital protocol will help them reduce product varieties, relatively increase production, and reduce product prices. A unified LR1130 battery digital protocol will benefit all relevant manufacturers and achieve a win-win situation in the market.

(2) Research on the characteristics of batteries such as cadmium nickel, hydrogen nickel batteries and lithium-ion batteries. Only with a detailed understanding of the characteristics of these batteries can we detect and control their various performance indicators, provide first-hand information for the digitization of batteries, and provide reference for the design and development of related electronic equipment such as intelligent charging controllers.

(3) Dynamic data acquisition and processing technology for digital batteries. It mainly collects data such as LR1130 battery voltage, current, temperature, etc., and after digital quantization processing, obtains accurate voltage, capacity, internal resistance, and temperature data to be displayed on the LCD or used for communication transmission.

(4) Data communication technology. Data communication is an important part of realizing LR1130 battery digitization. The existing foreign digital LR1130 battery communication standard is: SMBusV2.0. After the dynamic data of the LR1130 battery is processed, it is continuously transmitted to the CPU of other electronic devices (or host) through the transmission driver through the interface in a standard format. If it is a digital LR1130 battery system, the host can take corresponding measures according to the current status of the LR1130 battery.

(5) Intelligent charging control technology for digital batteries. The intelligent charging technology that matches the digital LR1130 battery must be able to communicate with the digital LR1130 battery and realize automatic fast charging control. At present, advanced chargers have been digitized and intelligentized. All operations of the charger are completed by the microprocessor, which can realize the functions of LR1130 battery type judgment, selection of charging current according to user requirements, multiple full judgment methods, multiple protection measures, LR1130 battery charging capacity display, simultaneous or sequential charging of multiple batteries, and sound and light prompts of LR1130 battery fullness. The charging method can be constant current, constant current constant voltage and auxiliary pull-down negative pulse, which can increase the maintenance function of the LR1130 battery, improve the LR1130 battery life through LR1130 battery maintenance, and can be used as an AC adapter to directly power mobile electronic devices.

Digital LR1130 battery is a new topic in the development and application of secondary power supply. The advantages of digital LR1130 battery are also unmatched by other non-digital batteries. Its research, development and promotion and application will not only inject new vitality into the LR1130 battery industry, but also provide a lot of convenience for people's production and life, which has important practical significance.
