Lead acid batteries are an important part of most energy storage applications. Managing these applications is complicated by the inherent difficulty of following the evolution of important battery parameters; more specifically, the State of Charge (SOC), State of Health (SOH) and Ampere-hour capacity (AHC). This article shows that the Two-Pulse Load Test is a simple and reliable method to determine...
This paper presents a small-scale hybrid energy storage system (HESS) that combines ultracapacitors and lead-acid batteries. It also comprises a controllable DC power source and a power resistor, as well as the bidirectional DC-DC converters to interface the different elements with a common DC bus. The system is designed for performance analysis, modeling and control validation purposes. The design...
