This Acciona challenge is looking for reliable solutions to monitor the charge status of lead batteries in photovoltaic systems.
Can you come up with a solution for the monitoring of the charge status of lead batteries in photovoltaic systems? Participate in this ennomotive social challenge to help isolated communities in Mexico and Peru.
Accurate monitoring of the charge status of lead batteries in photovoltaic systems (isolated populations in Mexico and Peru)ACCIONA Microenergia foundation is dedicated to bringing electricity to isolated and marginalized rural populations in Peru and Mexico using domestic photovoltaic systems. These systems consist of 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 a 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! Evaluation criteria 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
