Abstract
A battery monitoring system prevents damage to a device utilizing stacked battery cells, reduces the time required for battery replacement, and increases the capacity and reduces the size of the battery monitoring system. A battery unit includes: two or more battery cells configured to generate a DC voltage; two or more measurement units configured to measure a voltage value of the two or more battery cells and obtain measurement signals representing a measurement result; two or more transmission loop antennas configured to generate an AC magnetic field corresponding to the measurement signals; a reception loop antenna configured to receive the AC magnetic fields and generate a reception signal corresponding to the AC magnetic fields; a receiver configured to demodulate the reception signal to generate information representing the measurement results; and a magnetic core that runs through the transmission loop antennas and the reception loop antenna.
