Analysis on large-capacity storage battery discharge of intelligent energy-feedback device

Abstract

Abstract-The reliability of DC operating power is largely decided by the storage battery in power system. In order to satisfy large-capacity storage battery discharge demand and requirements for energy-saving and emission-reduction, a new intelligent battery discharging device that can feedback energy was designed. The device is introduced in details including the circuit structure, parameters design and control methods in this paper. The experimental results indicate that the device has a good discharge performance, small discharge ripples, good stability and reliability, convenient and visual monitoring, and a good engineering application value.
