Extensive research done into:◦ Nissan leaf battery and other li-ion batteries◦ PV panels◦ DC/DC converters◦ Maximum Power Point Tracking (MPPT)
Begun designing small scale charging system to prove concept◦ PV panel, li-ion cell and charger chosen◦ Buck converter will be used, inductor and capacitor values to be
chosen◦ MPPT will be implemented using PWM from an arduino to
control the duty cycle (Perturb and Observe MPPT)

Test Spectra 10W PV panel to determine I-V and P-V curves Choose suitable current sensor Test charge li-ion cell with DC source to determine charging
profile
Create SPICE simulation circuit to help choose appropriate values for the buck converter components

Design and do detailed simulation of full size system using SPICE◦ Scale up demonstration SPICE model◦ Will most likely have to change model to a boost converter for
full size system◦ Alter component values accordingly◦ Analyse the system at various operating conditions (full load,
half load etc.) Compare full size DC charging system with alternative DC-
AC-DC system (better efficiency?) Compile results and write final report
