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 (B)

At present, the People’s Liberation Army rely on national economic development and Sony vgp bps2c battery scientific and technological progress, to meet national security needs, weapons and equipment as the accelerating revolution in military affairs with Chinese characteristics and an important material base, is accelerating its modernization process; and the extensive application of electronic information technology, In the process of modernization of weapons and equipment to occupy a dominant position and has become an important factor in the decision, one outcome of a war.

In order to promote the building of military information, speed up the modernization of weapons and equipment to promote the military batteries, power supply and battery technology, power business users with the military exchanges and cooperation, the better to show battery power at VGP-BPS10 home and abroad of military technology, level of development, to promote the field of international exchanges and cooperation to build a good platform, in the Ministry of Information Industry Bureau of the strong support of military electronics, by the Chinese military network to host the second session of the National Military battery power technology and application workshop will be held in 2007 6 29 held in Beijing, this seminar will have a professional product display area, the organizing committee warmly welcome enterprises to participate. By then, the organizing committee will invite more research institutes and technical personnel to participate in this meeting, I believe that through all these efforts, companies will learn from many of the services for national defense and how to enter the military market information, establish relevant business contacts, make new friends, gain new VGP-BPS9 B , VGP-BPS9 S opportunities for development.
