INTERNAL STATE DETECTION SYSTEM FOR CHARGE ACCUMULATING DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an internal state detector for a charge accumulating device for a vehicle of a neural network type, capable of measuring precisely electric energy as to a charge accumulation condition. SOLUTION: A battery state quantity (open circuit voltage, an internal resistance or the like) in prescribed capacity of discharge from determination of full charge is input into a neural network part 107, in addition to a voltage history and a current history, in order to find the charge accumulation condition (SOC and SOH) by neural network computation.
