Title:
POWER CALCULATING APPARATUS AND POWER CALCULATING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/163936
Kind Code:
A1
Abstract:
The purpose of the present invention is to allow a power value of power supplied via a power line to be specified at low cost. In a power measuring system 10 provided with a power calculating apparatus 1 for calculating the power value of power supplied via a power line L6, the power calculating device 1 is provided with a reading unit which reads, from a serial bus SB1, a CAN frame Fc transmitted via the serial bus SB1 for CAN communication, wherein the reading unit reads, from the serial bus SB, a voltage value data frame as a CAN frame Fc which can specify the voltage value of a first voltage applied to the power line L6 and a current value data frame as a can frame Fc which can specify the current value of a current flowing in the power line L6, and outputs the read results to a processing unit; and the processing unit calculates a power value on the basis of the voltage value specified on the basis of the voltage value data frame and the current value specified on the basis of the current value data frame.
