CHARGE EQUALIZATION APPARATUS AND METHOD FOR SERIES-CONNECTED BATTERY STRING |
摘要 |
Provided are a charge equalization apparatus and method for a battery string connected in series, and more particularly, are a charge equalization apparatus and method that efficiently perform charge equalization while reducing entire complexity and volume and lowering production costs through a configuration that an individual battery included in a battery string shares a single voltage sensing module and a single charge equalizing module; a switch block of a two-stage structure forms a current path for measuring voltage of individual batteries included in the battery string, and at the same time, forms a charging or discharging path of a low-charged or over-charged battery among the battery strings; and a switch device having low withstand voltage is used. |
