Hi everyone, i am new to this forum Welcome to the forum! I am supposed to create an intelligent battery charger for my school project Note the key words there: it's your project: that means that you are supposed to do the work - yourself Of course, people will be happy to help if you have a specific questions - but the bulk of the work must be your own i totally have no knowledge at all. School projects are set to test what you have learned during the course (both in class and your own study), and that you can apply it to a real-world problem. In setting this project, your school thinks that you should be able to do it - if you feel that is not the case, then you need to discuss that with your teacher! Hope you guys out there could give a little hand and help me out. Help you out with what, exactly? The first stage of any project is Research - that is, searching & studying The Literature to find out the information you need. In your case, you need to find out: 1. The charging requirements & characteristics of the 4 kinds of battery; 2. What are the techniques currently in use for charging these kinds of batteries. Google is your friend here - but don't forget old-fashioned research in the library with the printed books, journals, etc... Note that the actual manufacturer of the kit (and the microcontroller that's on it) is Silicon Labs: http://www.silabs.com They also publish lots of Application Notes, examples, etc - search on their site to see if they have anything useful. Don't limit yourself just to information specifically for the C8051f120: remember that it's the principles and techniques that matter - not the specific microcontroller. Other manufacturers will also have examples of using their products; eg, I think Atmel have some application notes on using their AVR microcontrollers as battery chargers... Element-14 is a general component distributor. You can get a lot of information from their site; eg, they sell batteries - so look for battery information; identify manufacturers, and find their websites. What do the manufacturers advise about charging their batteries? There are chips available for battery charging. Often, their Datasheets will describe the techniques used; the manufacturer's Websites often have useful information. There is plenty of information out there - it is your job to find & apply it! |
