Health status and diagnosis of batteries in renewable energy systems: An overview

A battery is a device that converts chemical energy directly to electrical one. In the context of renewable energy, the purpose of using batteries is to store the generated power from solar panels, wind turbines or from other renewable energy sources. In this paper, an overview of the batteries used in green energy systems is discussed. The health status of these batteries is treated. Finally, an overview of the current methods using in the diagnosing of the lead acid batteries degradation is also given and discussed.
