Electric vehicle charge control system

摘要

The usage pattern of an electric vehicle including the amount of power consumption of a battery on each day of the week is extracted from usage histories of the vehicle in a predetermined period. When the vehicle goes home after one day's operation and is connected to a charging apparatus, a charge determination unit predicts a usage pattern of the vehicle on the next day and determines whether the vehicle can operate on the next day with the remaining amount of power of a battery in the vehicle. When it is determined that the charging of the battery is necessary, the battery is charged until it reaches the target remaining amount of power. The target remaining amount of power is determined on the basis of the amount of power consumption in the predicted usage pattern so that the full charge is prevented and the number of charges is reduced.

主权项

1. An electric vehicle charge control system comprising:
a history recording unit configured to record a usage of an electric vehicle including an amount of power consumption of the electric vehicle in each period as a period-by-period usage history; a charge determination unit configured to predict a future amount of power consumption of the electric vehicle from the period-by-period usage history, determine whether charging of a battery in the electric vehicle is necessary on the basis of the predicted future amount of power consumption and a present remaining amount of power of the battery, and calculate a target remaining amount of power that is a level to which the battery is charged in a case where it is determined that charging of the battery is necessary; and a charging unit configured to charge the battery on the basis of results of the determination of whether charging of the battery is necessary and the calculation of the target remaining amount of power which are performed by the charge determination unit.
