Title:
CURRENT VALUE TRANSMITTER, CURRENT VALUE RECEIVER, AND CURRENT VALUE DETECTION UNIT COMPRISING THOSE
Document Type and Number:
Japanese Patent JP2016218763
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a current value detection unit allowing a current value to be confirmed at a desired place by communicating the current value by radio.SOLUTION: An electrode of a storage battery is connected with a connection terminal 22a, and an electric product is connected with a connection terminal 22b or 22c. A current value detection unit 24 detects a current value on the basis of change in a magnetic field due to current, and a radio transmission unit 28 converts the current value into a digital signal to transmit the digital signal to a current value receiver 40 by radio.EFFECT: A current value detection unit can be made small because a current value is measured on the basis of change in a magnetic field, and the current value can be measured without using a shunt resister or the like. In addition, because heat generation due to current measurement can be reduced before it happens, water resistance can be enhanced by sealing it with resin.SELECTED DRAWING: Figure 1
