how to charge batteries?
can i charge a battery in serial or does it have to be parallel?
- I'm trying to make a custom charger for my MP3. i need five rechargeable NiMH batteries at 1.2 V each for a total of 6V.
- then it goes through a 5V regulator and into a female usb plug.
- can i charge the batteries in series with 6 V or does it have to be 1.2V charged in series.
- or can it not be charged in series and i have to charge it in parallel at 1.2 V.
- then my next question is can i charge a battery in parallel at 1.2V and use it in series at 6V with diodes so they don't sort shortage, at the same time.
- also if i can't charge in series then why do some phones charge in series? phone batteries are in series and are changeable. so can you charge batteries and series?
also if i can't charge in series then how do car batteries charge? car batteries are six 2V in series and they charge in 12V so how can car batteries charge in serial?
NiMH batteries do not like to be overcharged. Most of the better commercial chargers charge them individually although some charge them in pairs. They also monitor for the telltale little voltage dip that is indicative of a full charge.
The first link has information about a charge controller chip that you can use to build a charger for your 5 cell pack.
Your second challenge is regulating your 6 volt pack to produce 5 volts as your pack goes from 6.25 volts fully charged to 5 volts with the cells nearly depleted. A common 7805 type regulator requires an input voltage about two volts higher than the desired output voltage. There are "low drop out" types that require less but you still won't be able to use the full capacity of your pack before it goes out of regulation.
There are switching regulator designs based on chips such as the MC34063A that you may consider but they are much more complex.
