Abstract
A current measurement apparatus configured to quickly block current. The current measurement apparatus includes a first terminal, a second terminal, a resistor interposed in a separated space between the first terminal and the second terminal; a circuit board, a control unit mounted on the circuit board and configured to measure a current flowing in the resistor by using a voltage value between the first terminal and the second terminal and a resistance value of the resistor, and a cutting unit located above or below the resistor and configured to cut the resistor according to a control signal of the control unit.
Claims10
A current measurement apparatus, comprising:
- an electrically conductive first terminal;
- an electrically conductive second terminal spaced apart from the first terminal by a predetermined distance;
- an electrically conductive resistor positioned in a space between the first terminal and the second terminal, wherein a material of the electrically conductive resistor has a greater specific resistance than materials of the first terminal and the second terminal;
- a circuit board including an electric path, the circuit board positioned at a side portion of the first terminal and a side portion of the second terminal, and electrically connected to the first terminal and the second terminal, respectively;
- and
- a control unit mounted on the circuit board and configured to measure a current flowing in the resistor based on a voltage value between the first terminal and the second terminal and a resistance value of the resistor,
- wherein the control unit is configured to issue a control signal to cut the resistor based on the measured current,
- wherein the circuit board includes a body portion positioned at the side portion of the first terminal and the side portion of the second terminal, a first extending portion extending in a horizontal direction from the body portion and positioned on a surface of the first terminal, and a second extending portion positioned on a surface of the second terminal.
