Patent attributes
A leak detection device includes a pulse signal outputting portion that outputs predetermined pulse signals to a positive connecting wire connected to a positive side of a battery and a negative connecting wire connected to a negative side of the battery. A response waveform detecting portion of the leak detection device detects a positive response waveform for the pulse signal output to the positive connecting wire and a negative response waveform for the pulse signal output to the negative connecting wire. An amplitude ratio calculating portion calculates an amplitude ratio based on the positive response waveform and the negative response waveform, and a leak detecting portion detects a leak between the battery and a ground based on the amplitude ratio.
