ABSTRACT:
A resistance checker portion for terminal posts of an energy storage device includes a series branch formed of an ohmic resistor at a switch connected in parallel to the energy storage device through the terminal posts. Brief closing of the noramlly open switch causes a voltage jump in the series branch which is a direct measurement of the resistance of the terminal posts. An evaluator measures the voltage jump and calculates the contact resistance of the terminal posts therefrom.
