<p><P>PROBLEM TO BE SOLVED: To provide a battery controller capable of suppressing the degradation in battery performance, even if two batteries connected in parallel have different temperatures. <P>SOLUTION: The battery controller (1) supplies power to vehicular electric equipment (20), and controls charging/discharging to the two batteries (14, 16) charged by a vehicular generator (18) and connected in parallel. The battery controller has a power feeding switching means (4) for switching power feeding to the vehicular electric equipment from each battery; a charging switching means (6) for switching charging in each battery from the vehicular generator; detecting mean (8, 10) for detecting the temperatures of each battery; and a controlling means (2) for switching the power feeding switching means to allow only the battery having a lower temperature to feed power, and switching the charging switching means to allow the battery having a lower temperature to be charged, when batteries have a temperature difference over a specified difference value. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
