发明名称 Remaining-capacity dispersion detecting apparatus and remaining-capacity control apparatus for battery pack
摘要 A remaining-capacity dispersion detecting apparatus for a battery pack having a plurality of cells includes a total voltage sensing section adapted to sense a total voltage which is a terminal voltage of the whole of battery pack; a storing section adapted to store a value of the total voltage when the battery pack becomes under unloaded condition from loaded condition; and a dispersion detecting section. The dispersion detecting section is adapted to detect a value of the total voltage at a time of activation before the battery pack becomes under the loaded condition from the unloaded condition, to compare the currently-detected total voltage value with the total voltage value previously stored by the storing section, and to detect a dispersion in respective remaining capacities of the plurality of cells in the case where a difference between the currently-detected total voltage value and the previously-stored total voltage value is greater than or equal to a predetermined value.
