Abstract

The disclosure relates to a method of monitoring signal delay (220, 222, 224) at a battery (140) of a vehicle (10) by utilizing a switching circuitry (100), the switching circuitry (100) comprising a first path (110) comprising a first switch (112), a second path (120) comprising a second switch (122), a parallel third path (130) comprising a third switch (132) and a resistor (134) in series with the third switch (132); the method comprising closing (410) the first switch (112) and opening the second switch (122) closing (420) the third switch (132) detecting (430) a change in an electric property of the battery (140) in response to the closing of the third switch (132) and determining (440) the signal delay (220, 222, 224) by determining a delay in the detected change in the electric property in response to the closing of the third switch (132).
