A product purchase system includes a first communication terminal carried by an advertising user, a second communication terminal provided to be movable with a vehicle, and a server. The first communication terminal sends advertisement product information indicating a product worn or held by the advertising user to the server. The second communication terminal sends a product search request including second position information and second time information to the server. The second position information indicates a position of the vehicle when a specific action performed by an occupant in the vehicle is detected while the vehicle is moving. The second time information indicates a clock time when the specific action is detected. The server extracts candidate product information from the advertisement product information, based on the second position information and the second time information. The server then sends the extracted candidate product information to the second communication terminal.

A charging system includes a charging controller and an estimated completion time deriver. The charging controller adjusts a temperature of an on-board battery with a heater so that the temperature of the battery is kept equal to or higher than a predetermined temperature. The battery is chargeable with electric power supplied from a power supply outside a vehicle. The charging controller charges the battery with charging power excluding temperature adjustment power consumed by the heater from permitted suppliable power supplied from the power supply to the vehicle. The estimated completion time deriver derives an estimated completion time based on an estimated value of the permitted suppliable power in a future and an estimated value of the temperature adjustment power that is derived based on an estimated value of an outside air temperature in the future. The estimated completion time is a time when charging is predicted to complete.

In an electric charging system, an electric charger and an electric vehicle is connected via a charging cable, and charging power is provided to a battery of the electric vehicle via the charging cable. The electric charger calculates a voltage drop based on a supply current Is of the electric charger and an electric resistance of the charging cable. The electric charger compares a supply voltage of the electric charger with a determination value, and, if the supply voltage reaches the determination value, determines that the battery is charged to a fully-charged state. The determination value is updated by adding the voltage drop to a preset determination base value so as to take the voltage drop of the charging cable into account.
