METHOD AND DEVICE FOR ESTIMATING BATTERY'S DISCHARGEABLE CAPACITY

摘要

A voltage drop estimating means (23a-1) estimates a drop in a battery terminal voltage when a maximum current at a high-efficiency discharge to a load is allowed to run continuously, and a dischargeable capacity estimating means (23a-2) estimates an electric amount, obtained by deducting a non-dischargeable electric amount determined based on a voltage drop estimate by the voltage drop estimating means (23a-1) from an electric amount dischargeable in an arbitrary fully-charged condition, as a dischargeable capacity capable of continuously discharging a maximum current from a battery via a load.
