Is there to modify a 5v power supply to pulse a charge a smart phone battery using diodes
Maybe no putting in the right term. The 5v supply puts a steady voltage into the battery."pulse charge a smart phone battery"? I have no idea what you are asking? Can you define pulse charge? Smart phones I am familiar with you apply 5.0 VDC and the phone controls its charge.
Not quite exactly. The 5.0 volt supply provides 5.0 volts to the battery charge circuit which controls the battery charge process.The 5v supply puts a steady voltage into the battery.
At least the battery packs on my HP laptops have far more circuitry than shows in that simple block diagram. Both the battery pack and the charger are able to identify themselves as OEM devices, to the computer. Pulse charging may very well confuse things quite a bit. Pulse chargers DO WORK with lead acid batteries and there were some that worked with NiCad battery packs as well. But that is an older situation.the phone batteries their selves have a protection module integrated . . . the older ones of which limit the input current to 300mA ??? perhaps prevent the overcharging
. . .
if you want to get started with Li-Ion charging you have (to find* and) to dig through a pile of *relevant papers . . . and do a lot of tests also on your own (assuming you have the electronics lab equipment required and skills to use it + setup your experiments so the data retrieved would be . . . meaningful) -- in many cases you save your time and money . . . even if you buy not the cheapest smart desktop phone battery charger or an extra phone that is known to have a good charger inside it
