Study of Topology and Control Strategy of the Novel Bi-Directional Lithium Battery Charger

Abstract:

With the development of clean energy, lithium battery is paid more and more attention because of its outstanding energy storage characteristics .So the novel bi-directional lithium battery charger topology is presented in this paper and operating theory is analyzed clearly. It can make the energy bi-directional flow between the power grid and battery as needed. And it can also fully adapt to the lithium battery charging and discharging characteristics. Based on phase shifting control, the output voltage ripple and the inductor current ripple can be reduced in the condition of the same input and output, and the DC bus voltage can also be improved. This bi-directional lithium battery charger topology can be widely used in battery energy storage system.
