Abstract
A battery tester for efficiently extracting intrinsic characteristics of a battery. The battery tester comprises a sensing unit, a controller, a bi-directional power converter, and an energy storage unit so that energy discharged from a battery during testing is stored in the energy storage unit and recycled back to the battery. The battery tester uses a high current pulse test and a switching excitation test with a modified particle swarm optimization algorithm to analyze precise model parameters that can be used to describe the health conditions of a battery.
