Abstract
A battery monitoring apparatus a plurality of connection lines, a monitoring circuit, a first filter circuit, and a second filter circuit. The monitoring circuit is provided with a pair of sensing terminals for each pair of positive and negative electrode terminals of each of a plurality of battery cells of a battery pack. The plurality of connection lines includes a plurality of common line and first and second branch lines. The first filter circuit includes first resistors located on the first and second branch lines connected to the pair of sensing terminals, and a first capacitor located between the first and second branch lines connected to the pair of sensing terminals. The second filter circuit includes a second resistor located on the plurality of connection lines, and a second capacitor connected in series between the plurality of connection lines without passing through the first resistors or the second resistor.
