Abstract
A battery pack, and more particularly, a temperature compensated current measuring device which can accurately measure an actual current flowing in a circuit of a charging/discharging path in the battery pack. The temperature compensated current measuring device includes a conductor in which current flows, a temperature sensor disposed around the conductor to measure a temperature of the conductor, and a temperature compensated current detection circuit part electrically connected to two positions of the conductor to measure a voltage between the two positions, electrically connected to the temperature sensor to measure a temperature of the conductor, and measuring the current flowing in the conductor by using the measured temperature and the voltage as an input signal. Thus, it is possible to accurately calculate an actual charging/discharging current with the temperature compensated current measuring device and effectively control the charging capacity of the battery pack.
