Abstract:
1. A probe assembly for use with a battery impedance meter which includes a voltage sensing device having two terminals and a current source having two terminals, the probe assembly comprising: a first probe adapted for connection to a selected one of the positive and negative terminals of a battery cell; a second probe adapted for connection to the other one of the positive and negative terminals of said battery cell; a cable assembly including four wires each adapted for connection at a first end to a respective one of the terminals of the current source and the voltage sensing device, wherein at least three of the wires are constrained to extend in close proximity to each other from the battery impedance meter to the first probe, wherein one of the at least three wires which is connected to the current source and one of the at least three wires which is connected to the voltage sensing device are each connected at their second ends to the first probe, wherein at most one wire which is not constrained with the at least three wires is connected at its second end to the second probe; and at least one bypass wire having a first end connected to the second probe and a second end insulatively held to the first probe and connected to the second end of one of the at least three constrained wires which is not connected to the first probe.
