Final Year Project
Initial Presentation
Title: Solar Powered Battery Charging System
Supervisor: Maeve Duffy
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.
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
Proposed Time Scale
September/October:
 Review of Solar
Panels
 Review Mobile
Phone battery
chargers
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
Proposed Time Scale
November:
 Build and test DC/DC converter:
 Build prototype circuit on strip board
 Test and debug circuit
 Test circuit using solar panel as source
Proposed Time Scale
January:
 System and software interface design
 Specify system functionality
 Build and test additional hardware elements
 Implement user interface in Labview
Proposed Time Scale
February:
 System integration and development
 Test complete system
 Design modifications required for larger
panels
 Estimate energy savings provided by DC/DC
Progress to Date
 Review of Solar Panels
 Review of Mobile-Phone battery charger
 SPICE
