Accurate monitor the charge status of lead batteries in photo-voltaic systems (isolated populations in Mexico and Peru)
ACCIONA Microenergia foundation is dedicated to bring electricity to isolated and marginalized rural populations in Peru and Mexico using domestic photo-voltaic systems. These systems consist on a solar panel (80Wp), a sealed Lead battery (100 Ah) and a charge controller.
We are looking for a reliable, cheap and robust solution to accurately read the actual charge of a Lead battery, its operating regime during a minimum period of one month, and, if possible, at what point of its lifespan is at that moment.
The final objective is to incorporate such solution into these photo-voltaic systems to determine the actual battery operating regime, and to establish a strategy to drastically improve the Lead battery’s lifespan.
Help us improve the quality of the electricity service provided with domestic photo-voltaic systems for isolated rural families!
Contributions will be assessed according to:
- Lowest % error for battery charge reading
- Minimum lifespan cost (manufacturing, adaptation and maintenance)
- Minimum power consumption
- Evidence on the robustness of the solution
Acciona Microenergia foundation will give recognition for the winner and visibility through their web and social networks (Fb, Linkedin, Twitter).
The winner will keep the intellectual property and Acciona Microenergia foundation will have the right to use the solution.
This is a social challenge! We need your help to improve life of families living in areas where conventional power networks is not economically viable.
