Digital battery and related technologies
1 Introduction As people’s living standards improved, rechargeable batteries, especially large current batteries (lead-acid batteries, nickel cadmium and nickel-metal hydride battery) in the power sector, railways, the military has achieved an increasing number of applications, however, battery can be No reliable electricity, and achieve the required plant life, with the battery charge-discharge routine maintenance and management correct or not is closely related. As is now widely used batteries are not with intelligent detection devices, that is, digital batteries, so Hp 530 battery charge and discharge current size, the size of the terminal voltage, charge and discharge time, charge and discharge frequency, charge-discharge capacity, remaining capacity, battery internal temperature and life and other basic parameters, can only rely on manual measurements or roughly estimated that the event of errors, will be our normal production and lives of unpredictable consequences, as well as the electrical performance and life of battery and causing irreparable damage.
With the development of microprocessor technology, mobile electronic devices function on its own in terms of developing very fast, at present the vast majority of digital, intelligent, internal control circuit more or less completed by the CPU chip. But it is part of the power supply is extremely primitive, under normal circumstances is only one battery of the DC to the electronic equipment, while the battery’s own characteristics, status and other parameters are unable to provide electronic devices that can not be related to the electronic equipment data communications. This intelligent electronic devices increase, bringing new problems.
If the battery of various state parameters can be stored by the microprocessor, recording, analysis, control, printing and display, intuitive to provide to the relevant personnel, and to achieve and related electronic equipment for data communications, that is, digital technology, which not only can to reduce human error and extend battery life, but also be able to achieve related to intelligent control and electronic equipment unattended. Therefore, the battery of digital research and development is a significant issue.
2 The concept of digital batteries
The exact definition of the digital battery is still not harmonized. This concept comes from the rapid development of information industry, which mainly come from the world’s leading notebook computer design, production and suppliers. In practice, once the battery is dead when the key is bound to produce unpredictable losses, digital camera batteries idea is put forward in this case, with it, we will be able to grasp the battery status of work on the can be prepared in advance and timely replacement. The working conditions are talking about here should include the following aspects:
(1) the current size of the battery terminal voltage, charge and discharge current size, charge and discharge time;
(2) Current battery impedance, remaining capacity, the remaining charge and discharge time, the battery temperature;
(3) the current battery charge and discharge times, life.
In the actual development, the researchers found that only about the work of the battery status and does not meet our battery requirements, also need batteries to electronic devices and related data transmission, in order to achieve the battery switch, automatic battery charging and so on.
Clear from the foregoing: the so-called digital battery, which contains an ordinary rechargeable batteries, a digital battery control module, as well as the communication interface, complete the battery of the digital measurement and control management and data communication capabilities. In addition to the above-mentioned working conditions in digital form accurate visual display (or provide), but also to provide background information and identity of the battery data (such as battery manufacture date, manufacturer data, etc.); in the process of charging with the corresponding alarm protection measures (such as over-voltage protection, over-temperature alarm, etc.); same time, it should be consistent with some kind of communication protocols (such as system management bus, SMBus), has the host, intelligent charge controller such as communications interfaces, capable of information transmission and control. Schematic diagram of digital batteries are as follows:

3 Digital value of the battery status and development
Digital battery first started to develop from abroad. As early as 1995, the U.S. military have been digitized battery equipped troops, but these batteries are not highly digitized, versatility is not strong. According to online information-gathering that is limited, and foreign research and development of digital batteries by rechargeable batteries, control modules, of which control module of the software components should be consistent with the specific communication protocol. Posed by the digital battery digital battery system hardware includes: System console, digital battery (which can be one, it can be a number of pieces), intelligent charge controllers, AC / DC converter and transmit data bus network. Software, including the transmission of data communication protocols, data processing platforms and embedded operating system and the corresponding procedures. There are many foreign companies and enterprises to participate in research and development of digital battery, Intel Corporation and co-production of digital Duracell batteries, this product called PowerSmart, in line with SBS (Smart Battery System) standard. Motorola is also developing be broad user acceptance of digital batteries. Germany’s giant Varta batteries and Duracell companies are developing a new generation of digital batteries, this battery will soon be available.
From the battery industry in the tenth Five-Year Plan was informed that the United States, Japan and Europe accounted for 70% of the global battery market. Consumption of the battery, the United States per capita reached 25 / person; Japan’s annual per capita reached 20 / person. While China’s annual per capita consumption of less than 7 cells. Therefore, the battery in China, a great market. China’s battery industry focused on the mercury-free alkaline manganese batteries, Ni-MH power batteries, lithium-ion batteries, sealed maintenance-free lead-acid batteries, vehicle power batteries, fuel cells, solar cells in the development and production. In the army, the secondary battery, such as cadmium, nickel, nickel-hydrogen battery in a large number of equipment use, military research and development of lithium-ion batteries are also soon will be equipped with troops in the next period of time, there will be three kinds of batteries coexistence phenomenon.Therefore, secondary batteries in our digital, has great space for development. Meanwhile, the secondary battery digitized, people using battery-powered digital time, and will not in the normal work of a sudden power- down and affecting their work and a certain amount of loss; can be more scientific and reasonable or that the use of batteries, the battery will not be over-discharge and over-charge, can effectively extend Canon FS21 battery life; accurately display battery data and provide data to the host can be an effective state of the battery each corresponding control and processing; on the battery aging will also be the final warning prompt ; Therefore, the corresponding cells have a breaking capacity of Jane; constitutes a digital cell system can be used to remotely monitor the battery and the use of reliable data for efficient energy management. Thus, digital battery also has a high application value.
