Abstract
In this paper, a cycler system for the Lithium-Polymer battery with the large capacity of 120Ah is presented. This system is constituted as the two units for the charging and discharging. The Lithium-Polymer battery should be charged in CC and CV mode, and it is required a very high precision control of the voltage and current for the charging unit. To decrease the switching noises and harmonics, parallel operation method is adopted and utilized in the power conversion module. The discharging unit has a link AC system function to return the discharging energy of battery to AC line and has comparatively less thermal loss. These units are designed to be controlled and monitored by personal computer. The total system for the battery charging and discharging is described and presented.
