Electricity theft identification method, electricity theft identification device, and computer program product

An electricity theft identification device comprising:

• a memory;
• and
• a hardware processor coupled to the memory, and configured to:
• detect electricity theft based on a difference between a total amount of electric power supplied to a plurality of electric vehicles and a measured electric power amount, the total amount being calculated based on communication information including an amount of electric power supplied to each of the electric vehicles connected to a plurality of chargers, the measured electric power amount being measured by an electric power meter configured to measure an amount of the electric power supplied from a power supply to the plurality of chargers;
• determine likelihood of electricity theft of each of the electric vehicles connected to the plurality of chargers based on temperature information of at least one of the charger and the electric vehicle;
• and
• identify, as an electricity theft vehicle, the electric vehicle whose likelihood of electricity theft is determined to be a first level or higher when the electricity theft is detected.

A computer program product comprising a non-transitory computer-readable medium including programmed instructions that cause a computer to execute:

• detecting electricity theft based on a difference between a total amount of electric power supplied to a plurality of electric vehicles and a measured electric power amount, the total amount being calculated based on communication information including an amount of electric power supplied to each of the electric vehicles connected to a plurality of chargers, the measured electric power amount being measured by an electric power meter configured to measure an amount of the electric power supplied from a power supply to the plurality of chargers;
• determining likelihood of electricity theft of each of the electric vehicles connected to the plurality of chargers based on temperature information of at least one of the charger and the electric vehicle;
• and
• identifying, as an electricity theft vehicle, the electric vehicle whose likelihood of electricity theft is determined to be a first level or higher when the electricity theft is detected.
