Point granting device and point granting method

A point granting system that grants a point in accordance with a carbon dioxide emission amount reduced by use of an electrified vehicle, comprising:

• the electrified vehicle;
• a charging facility that supplies electric power to a battery in the electrified vehicle, wherein the electric power supplied from the charging facility includes electric power obtained from renewable energy;
• and
• a management device, wherein the electrified vehicle, the charging facility and the management device communicate with each other via a communication network,
• wherein the management device includes at least one processor programmed to:
• when the electrified vehicle is an externally chargeable vehicle, grant a point in accordance with a ratio of an electric power amount obtained from the renewable energy to a charged electric power amount;
• when the electrified vehicle is a vehicle that travels using electric power, grant the point in response to an actual electric power cost achieved by traveling being equal to or higher than a model electric power cost;
• obtain information from the electrified vehicle that travels using the electric power;
• calculate an amount of electric power to be charged by the electrified vehicle based on the obtained information, wherein the amount of electric power to be charged is a difference between consumed electric power and a remaining battery amount;
• when the electrified vehicle is the externally chargeable vehicle, predict a timing at which a ratio of the electric power amount obtained from the renewable energy to the amount of electric power to be charged from the charging facility by the electrified vehicle becomes highest;
• and
• transmit the predicted timing to the electrified vehicle as an optimal charge timing for the electrified vehicle to be charged by the charging facility.
