Title: CHARGING/DISCHARGING CURRENT ESTIMATION DEVICE
Abstract:
A current estimation device according to an embodiment of the present invention relates to a device for estimating a charging/discharging current of a battery pack, the device comprising: a shunt resistor connected between a first node and a second node, which are formed on a charging/discharging path of a battery pack; a shunt capacitor connected between the first node and the second node; a voltage measurement unit connected between the first node and the second node to measure a voltage applied to the shunt resistor; and a current estimation unit for estimating a charging/discharging current of the battery pack by using a voltage measured by the voltage measurement unit.
