Solar Powered Lead-Acid Battery Charger National Semiconductor RD-165 Applications Design Center - FD and RK November 2008 1.0 Design Specifications Inputs Output #1 VinMin=6.0V Vout1=12.4V VinMax=10V Iout1=0.09A 2.0 Design Description The lead-acid solar charger reference design not only shows how to efficiently convert solar energy into a charge current for lead acid batteries, but it incorporates additional circuitry to compensate for temperature and sunlight variances. A lead-acid solar charger is well-suited for applications such as automotive where a constant charge is needed to maintain an idle battery. A solar cell’s output current decreases with the reduction in sunlight (solar Irradiance), and the voltage of solar cells de- creases with increases in temperature. National’s lead-acid solar charger uses an 18-cell (3W) solar panel as the input source. The design comprises two stages: • The first stage monitors the solar panel voltages, and a SEPIC design using (LM5001 controller) provides the output voltage which tracks the input (solar panel voltage over the temperature range). A simple, cost-effective thermal monitor circuit that uses a string of BAT54 diodes tracks the solar panel voltage over the temperature range of 25°C to 100°C • The second stage takes the output of the first stage (SEPIC converter) and boosts the SEPIC voltage to nominal 13.3V at 25°C and 14.4V at 100°C. It also consists of a constant current control used to charge the 12V lead-acid battery. The charging current into the battery is also varied to ensure that maximum power capability of the solar panel is not ex- ceeded. This is accomplished by reducing the current that is fed into the battery at higher temperatures. Again, a cost-ef- fective thermal monitor circuit using a BAT 54 diode provides feedback that adjusts the output voltage and output current over the temperature range. 3.0 Features 1.
