    • In an A/D converting apparatus, a converting unit has an input terminal and an input-output characteristic. The input-output characteristic has temperature dependence, and the converting unit carries out a process of converting an input voltage signal to digital data. A temperature determining unit has information representing a relationship between a variable of an output of the converting unit and a variable of a temperature around the converting unit according to the temperature dependence of the input-output characteristic of the converting unit. When the specified voltage is applied to the input terminal of the converting unit, the temperature determining unit determines a value of the temperature around the converting unit based on the information and the specified voltage. A reducing unit reduces temperature dependence of the process of converting an input voltage signal to digital data based on the determined value of the temperature around the converting unit.

This charging method detects the voltage of each battery being charged and if any battery voltage exceeds the prescribed voltage, only the battery that exceeds the prescribed voltage is discharged, after a specified charging time, until its voltage drops to the prescribed voltage. Batteries that do not exceed the prescribed voltage are not discharged, and thereby all batteries are charged while balancing their voltages.
