In the cell phone canon bg-e6 battery grip charger standard uniform enforcement of June 14, after starting from August 1, PHS terminal charger and interface uniform standards will also be enforced when PHS terminal submission must meet the relevant technical requirements, otherwise do not I test.
It is responsible for the formulation and implementation of these standards “China’s fixed and wireless terminals Union” relevant persons introduced, the new PHS charger and interface with the Ministry of Information Industry to develop standards for mobile phone charger is fully consistent, from a cable and a USB the composition of the parent seat vgp-bps2 , vgp-bps2a charger port.
Conclusion
The innovation of this paper is a balanced two-way non-destructive charge-discharge program using an independent module form, the work simply (N-1) the number of modules connected to the vgp-bps2b , vgp-bps2c battery for the N group, the easy to implement and easy to maintain, in addition, in the charging and discharging the course of its automatic balancing capacity difference between adjacent cells to ensure that the battery pack all the batteries are in the process of charging and discharging the same level, thus preventing battery overcharge, over-discharge, thus extending battery packs working life. In addition, the use of microcomputer control mode, with control of simple Sony battery, easy to implement and low cost advantages. Experimental results show that this is a valid circuit.
