Abstract

A battery current measuring device includes a switching element configured to control charging and discharging of a battery, an A/D converter configured to convert a voltage value across the switching element into a digital value, a temperature compensation unit having a diode structure capable of compensating for a resistance change according to a change of temperature of the switching element, and a current calculation unit configured to calculate a current flowing through the switching element based on the digital value of the voltage value, and the A/D converter converts the voltage value of the switching element into the digital value using a reference voltage inputted from the temperature compensation unit.
