The demand for energy in our society has been increasing exponentially with our growing standard of living. The continued use of fossil fuels to meet these energy needs could lead to potentially catastrophic changes in the Earth's climate. Therefore, finding carbon-neutral energy sources and ensuring energy security are two of the biggest challenges that need to be addressed in the coming years. Recent technological innovations have finally brought us to the cusp of achieving these goals by providing cheap and reliable devices in micro-solar, smart homes , Internet of Things, etc. However, one of the biggest hurdles in the large-scale adoption of renewable energy devices is the high cost of energy storage. In this report, we describe an energy management system that uses cheap, recycled lead-acid batteries to bring down the cost of energy storage to make the adoption of renewable energy easier.
