APPARATUS AND METHOD FOR MEASURING CURRENT OF BATTERY

This abstract first appeared for US patent application 18396805 titled 'APPARATUS AND METHOD FOR MEASURING CURRENT OF BATTERY

Original Abstract Submitted

A battery current measurement apparatus includes a first sensor part connected to a battery and measuring a current thereof, a second sensor part connected to the first sensor part and measuring a current, a switch part connected to the second sensor part and switching connection of the second sensor part, and a processor calculating a current of the battery based on a first current value of the first sensor part and a second current value of the second sensor part, calculating a state of charge (SOC) of the battery corresponding thereto, and comparing the first current value with the second current value to detect a defective current sensor among multiple current sensors included in the first and second sensor parts. A corresponding battery current measurement method is also provided.
