STATUS DETERMINATION APPARATUS OF LEAD STORAGE BATTERY AND VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a status determination apparatus capable of appropriately calculating residual capacity of a lead storage battery irrespective of deterioration state of the lead storage battery. ! SOLUTION: The status determination apparatus includes: a full charge determination section 107 that is configured to determine whether a lead storage battery 2 is in a state of full charge based on a terminal voltage detected by a voltage detection section 102 and a charging current detected by the current detection section 103 during charging; a sixth calculation section 115 that is configured to, when the full charge determination section 107 determines the lead storage battery 2 is in the state of full charge, calculate a variation ΔV between a terminal voltage V12 on the lead storage battery 2 detected by the voltage detection section 102 after reaching the full charge and a terminal voltage V11 on the lead storage battery detected by the voltage detection section 102 after reaching initial
