<p><P>PROBLEM TO BE SOLVED: To provide a balanced charging controller for a battery and a battery module capable of charging the battery at balance. <P>SOLUTION: The balanced charging controller for the battery 100 includes: a voltage divider connected between a first and a second terminals, to supply a lower reference potential and an upper reference potential higher than the lower reference potential; a switching module having a first switch Q1 connected to the first terminal and the connecting point, and a second switch Q2 connected to the second terminal and the connecting point; and a balancing circuit connected to the connecting point, the voltage divider, and the switching module, to determine whether a balanced charging current is fed by the first switch Q1 or the second switch Q2, based on the potentials at the connecting point, the upper reference potential, and the lower reference potential. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
