Abstract
In the related art, the measurement error due to the internal resistance of the battery is not considered in the battery balance method, such that the battery balance is not accurate, or the battery balance process is frequently started and stopped. In exemplary embodiments of the invention, detecting battery voltage and balancing battery voltage are performed in different time, such that the difference of charge current/discharge current among the batteries due to the battery voltage balance process do not affect the battery voltage detecting.
