ACCUMULATOR FAILURE DETECTING DEVICE, ACCUMULATOR FAILURE DETECTING METHOD, ACCUMULATOR FAILURE DETECTING PROGRAM, AND COMPUTER-READABLE RECORDING MEDIUM CONTAINING THE ACCUMULATOR FAILURE DETECTING PROGRAM

摘要

A device detects a failure in an accumulator formed by connecting a plurality of accumulation portions including at least one accumulation element. Upon determining that the accumulator is in a state close to a failure state from a time interval between equalization processes on the plurality of accumulation portions, the device calculates a failure determination value from a charge and discharge capacity of the accumulator measured after the determination and makes a determination as to whether the accumulator is in a failure state using the failure determination value.
