LEAD STORAGE BATTERY STATUS DETERMINATION DEVICE AND VEHICLE

摘要

PROBLEM TO BE SOLVED: To properly calculate residual capacity of a lead storage battery irrespective of the type of the lead storage battery. ! SOLUTION: A status determination device 10 of a lead storage battery 2 include: a battery determination section 113 that determines the type of the lead storage battery 2 based on a residual capacity Ct calculated by a second calculation section 108 and residual capacity Cp calculated by a fourth calculation section 111; and a setting section 114 that sets a minimum voltage value Vmin stored in a storage 101 to a minimum voltage value according to the type of the lead storage battery 2 based on the determination result of the battery determination section 113. The battery determination section 113 determines the type of the lead storage battery from "ordinary item", "high output item" and "large capacity item" according to a difference between residual capacities Cp and Ct. The setting section 114 sets a corresponding minimum voltage value Vmin 1-3. ! COPYRIGHT:
