Abstract

En 中文

The use of electric power systems in the industrial field is continuously expanding due to the development and progress of new energy technology. As one of the core technologies of power systems, people are increasingly demanding higher performance from batteries. The battery management system plays an essential role in improving efficiency, safety and life-span of the battery pack and one of its main functions is the battery balancing function. This paper aims to discuss a novel battery balancing method using dual active bridge phase shift control technique. This technique has a much simpler circuit structure, reduced manufacturing cost, requires less space and offers more flexible control of balancing current than the current mainstream battery balancing methods.
