The two-way balanced design of the module

To extend battery life, charge and discharge the inspiron e1405 battery should be to enable all of the individual remain in the same state of charge, while the battery voltage is the battery inconsistency of the most intuitive and most easy to measure the performance of the form, so the ideological balance of charge gist is the charge-discharge process as much as possible to enable the VGP-BPS8, VGP-BPS8A battery to maintain the same level.

Based on the above reasons, this design is used to compare the parameters of voltage, through the MCU control, to achieve a high-voltage battery to transfer energy directly to the battery voltage is low. (Figure 2 omitted)

Among them, a balanced circuit used to implement the VGP-BPS9, VGP-BPS9/B battery between two adjacent energy balance; data acquisition circuit the battery parameters in real-time collection, the main acquisition parameters are the battery terminal voltage and temperature, through the A / D converted to give microcontroller for battery real-time monitoring; microcontroller to monitor battery state and also of the balance control circuit, once voltage difference was found between the battery reached a certain value, that is, to the corresponding FET send trigger pulse to turn-on voltage of the battery to the high inductance charge FET end, the inductor stored energy to supplement VGP-BPS9/S, VGP-BPS9A/B battery charging voltage is low.

Military Battery Power Supply Technology (A)

Network sponsored by the Chinese military to a “harmonious integrity of innovation sony vgp bps9 ” as the theme of the second session of the National Military battery power technology and applications will be held June 29 in Beijing.

By then, from the General Armament Department, Ministry of Information Industry, military chemical power research and development center, the military information technology advisory committee of experts, the Second Artillery Equipment Research Institute, China South Power Technology Research Institute, Ministry of Communications Equipment Bureau of the General Staff General Staff, General Logistics Department Communication Automation Bureau, the Air Force communications Sony VGP-BPS2A station of command automation station, the General Staff Communication Department of Communication test base, China Electronic Science and Research Institute, Institute of Science and Technology Department, naval equipment, the General Staff Communication Department of the Institute of more than 61 leaders and experts will visit the site.

Network sponsored by the Chinese military’s first session of the National Military battery power technology and application in July 2006 workshop was successfully concluded in Beijing in the last session, invited the army information technology advisory committee of experts, assembling land and equipment Branch provides the Department of General Staff Communication the Ministry of Equipment Bureau, the Second Artillery Equipment Research Institute, the General Logistics Department communications Sony VGP-BPS8 command automation Board, 61 General Staff, General Staff communication experiments Battalion, National Defense University, Academy of Military Sciences, the Navy, Air Force, the Beijing Military Region, a hospital space, space two homes, space Hospitals aerospace eight homes, space launch Technology Research Institute, weapons, ships, China Electronics Technology Group and other research institutes attended the seminar, as well as Israel TANDILAN batteries, Taiky, the United States ACTIVE POWER batteries, France SAFT batteries, Santak electronics, power source, the new Ray energy, sun power, CLP China Star and other well-known enterprises to participate NP-20 in this discussion.
