Microcontroller Control Software Design
The key is to balance the control of the module parameters of the inspiron e1405 battery voltage collection and trigger pulse output FET and battery status to determine the control software to achieve a balanced charge and discharge at the same time should also be able to realize the battery overcharge, over discharge instructions to protect the other When the battery temperature exceeds its operating temperature range can also be a timely manner to protect the output instructions.
Experiment and result analysis
With the two lead-acid VGP-BPS8, VGP-BPS8A batteries do 12V/4Ah comparative experiments, before the experiment, respectively, the battery discharges to the voltage is not balanced, and then use the module to do a balanced two-way balanced charge and discharge experiments, test the initial conditions the same. The experimental results shown in Figure 4,5, can be seen from the diagram in the absence of a balanced case, the charge and discharge of the latter, the battery voltage difference between the more and more, while the two-way balance of modules in the process of charging and discharging effectively narrowed 2 between the VGP-BPS9, VGP-BPS9/B battery voltage, particularly in the charging and discharging the battery too late to avoid the charge and over-discharge, protect the battery pack.
In the future, PHS mobile phone charger can be universal.
“At present, the alliance has not raised objection to the implementation of standards manufacturers, so we are on schedule the implementation of the standard expressed optimism about the prospects.” Yesterday, China’s fixed and wireless terminals stakeholders Secretariat of the VGP-BPS9/S, VGP-BPS9A/B League told this newspaper.
