Patent ID: 7012404

Claim:
A terminal assembly for measuring electrical current passing to and from a battery post, comprising: an electrically conductive collar having an inner surface for contacting a battery post; an electrically conductive terminal for receiving a load connector; an electrically conductive resistor having a resistance from about 50 microOhm to about 200 microOhm extending between outer surfaces of the collar and the terminal, wherein current flow from the battery post travels through the resistor from the collar to the terminal and current flow to the post travels through the resistor from the terminal to the collar; a first lead electrically connected to the outer surface of the collar, and a second lead electrically connected to the outer surface of the terminal; a volt meter connected between the first and the second leads for measuring the voltage drop across the resistor; and a computer, said computer including: memory storing the resistance of the resistor; and a processor programmed to, receive the measured voltage drop from the volt meter, retrieve the resistance from the memory, and calculate current flow through the resistor based on the measured voltage drop and the resistance.
