1. Final Year Project Initial Presentation
Title: Solar Powered Battery Charging System
Supervisor: Maeve Duffy

2. Background
The aim of this project is to design, build and test a system that will control the charging of multiple mobile phone batteries simultaneously.

3. Background Review output power levels of available solar panels
Develop system to control the charging of multiple mobile phone batteries
Consider how the circuit/system design will change for larger panels
System will include power management functions and information display

4. Proposed Time Scale September/October: Review of Solar Panels
Review Mobile Phone battery chargers

5. Proposed Time Scale October/November: Design DC/DC converter
Suitable circuit for range of source and load voltage and power levels
Determine switch specifications
Simulate in SPICE

6. Proposed Time Scale Build and test DC/DC converter: November:
Build prototype circuit on strip board
Test and debug circuit
Test circuit using solar panel as source

7. Proposed Time Scale January: System and software interface design
Specify system functionality
Build and test additional hardware elements
Implement user interface in Labview

8. Proposed Time Scale February: System integration and development
Test complete system
Design modifications required for larger panels
Estimate energy savings provided by DC/DC

9. Progress to Date Review of Solar Panels
Review of Mobile-Phone battery charger
SPICE
