Lossless equalization principle a two-way

Two-way non-destructive principle of a balanced vgp-bps2 , vgp-bps2a charge and discharge the program structure as shown in Figure 1, each cell balancing FET shunt circuit are two Q, two diodes D, and an energy storage device composed of inductor L. (B) is a picture out of three when the circuit connecting the battery to link the case. In order to charge, for example, assume that an equilibrium in the two cell voltage circuit that there is no balance, such as VB1> VB2, then the Q11 conduction, the battery B1 to the charge inductor L1, when the Q11 deadline, L1 in order to freewheeling, and B2, D12 constitute a circuit, the vgp-bps2b , vgp-bps2c energy stored in the inductor transferred to B2, the realization of the energy transfer from B1 to B2.

By the same token when the VB1 < VB2, then through the Q12-off to achieve the energy transfer from B2 to B1, that is, the circuit is a two-way transfer of energy balance device. Although the energy transfer only between adjacent canon bg-e6 battery gri cells, due to the trend of energy transfer is always from the high-voltage battery to pass to the low battery voltage, and thus ultimately the balance of the whole group of batteries. Discharge, principles and canon eos 20d battery grip charging basically the same.

Since all the equilibrium structure of the circuit are the same, so easy to achieve a modular design.

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.
