Abstract: A power conversion device includes an inverter which converts a DC power supplied thereto from a power supply device to an AC power using an operation of a switching element and outputs the AC power toward a load a current meter which measures an output current from the inverter, and a control unit which controls the operation of the switching element to change an output voltage waveform from the inverter. The control unit changes the output voltage waveform on the basis of the measured output current.

Abstract: A battery monitoring system includes a monitoring unit that monitors a battery and a higher device that is provided with monitoring data obtained by monitoring of the battery by the monitoring unit and saves, by using a blockchain, at least part of specific information included in the monitoring data. The higher device includes a block generation unit that generates a new block including a hash value based on the at least part of the specific information and a last block linked at an end of the blockchain, and an external communication device configured to save, in a distributed manner in a plurality of external devices, the new block generated by the block generation unit. At least one of the monitoring unit or the higher device is provided with a data protection unit configured to ensure reliability of the monitoring data.
