With the rise of the continuous development of the national economy, energy, electricity, transportation, telecommunications, environmental protection and other areas of modern requirements. Used as back-up battery system energy in large quantities will not allow power-off all power systems, is a vital battery backup power systems. Also, the battery system will be in different industries, more and more widely applied. Battery life status is normal, a direct impact on applications in a variety of devices, normal, reliable and safe operation. In particular, unmanned site and e-commerce center, bank back-up battery is particularly important.
After testing and optimization of the battery group in each monomer battery performance, there are still differences, these differences in the long-lasting process of the battery by the small differences in the environment (such as the temperature difference) in varying degrees to new to create differences. After a long single-significantly reduces battery power, a serious impact on battery power, or even accidents, and requires early diagnosis of single-cell performance degradation and premature failure. In addition, the single-cell performance degradation or failure will reduce the battery SOC (state of charge) value, because poor performance provides a single battery, the battery charge level. A battery has a rule by a series of single cell or battery modules connected in series; performance of the backward single battery can cause an early termination of the total discharge of the battery. And therefore must be fitted battery fault diagnosis expert system. By the diagnostic system to reach the battery failures and risks of early warning systems so that they can effectively increase the battery electric vehicle driving range and interference-free hours, thus minimizing the maintenance burden and thus ensuring reliable operation of electric vehicles can.
Electric vehicles, in whole or in part, from the energy storage battery. Constrained electric vehicle technology development and industrialization of electric vehicles as a major problem is the energy storage cell and its application. Battery with the use of a prominent issue is the difference between the individual cells, there are inconsistencies, vgp-bps13a/b vgp-bps13b/b,VGP-BPS10A,VGP-BPS10A/B,VGP-BPS10B,so that the battery does early detection of inconsistencies and mistakes in crucial technical problems. Need to develop a series of early fault diagnosis system. Through expert diagnosis system we can achieve the early detection of diseased cells, but also to enable the accurate remaining capacity estimation model to be, this can prolong battery life and to further reduce battery costs and extend the range of electric vehicles by vehicles to improve drive reliability. The system and technology research has theoretical value and the promotion of electric vehicles, industrial importance.
