Abstract

This method for diagnosing a battery pack having a configuration in which a plurality of cells are connected in series, using a system for obtaining detected data including the current and temperature of the battery pack and the voltage of each cell, includes: a step of calculating an electric charge capacity and a state of charge (SOC) of each cell, using the current and the temperature, the voltage of each cell, an open circuit voltage (OCV) - SOC function, and an OCV - resistance table, and calculating an amount of unbalance, which is an estimated value of the SOC, and the resistance for each cell when the battery pack is fully charged; and a step of calculating the energy capacity of the battery pack using the electric charge capacity, the amount of unbalance, and the resistances. As a result, the energy capacity of the battery pack can be calculated accurately, even in an unbalanced state.

Abstract

A method for synthesizing cDNA possessing a consecutive sequence starting with a nucleotide adjacent to a cap structure of mRNA, which comprises (i) a process for annealing a double-stranded DNA primer and an RNA mixture containing mRNA possessing a cap structure, (ii) a process for preparing a conjugate of an mRNA/cDNA heteroduplex and a double-stranded DNA primer by synthesizing the first-strand cDNA primed with the double-stranded DNA primer using reverse transcriptase, and (iii) a process for circularizing the conjugate of the mRNA/cDNA heteroduplex and the double-stranded DNA primer by joining the 3' and 5' ends of the DNA strand containing cDNA using ligase. This method enables us to efficiently synthesize a full- length cDNA possessing a consecutive sequence starting with a transcription-start- site nucleotide from a small amount of RNA by small processes.
