Charging control system and charging control method

Abstract

A charging control system that controls charging for a vehicle that runs on electricity, including at least one rechargeable unit; a charging unit that charges the vehicle or the rechargeable unit with electricity; and a charging control unit that controls charging such that when the charging time for the vehicle by the charging unit is a predetermined time or shorter than the predetermined time, the vehicle is charged with electricity from the rechargeable unit.

What is claimed is: 
     
         1 . A charging control system that controls charging for a vehicle that runs on electricity, comprising:
 at least one rechargeable means;   charging means that charges said vehicle or said rechargeable means with electricity; and   charging control means that controls charging such that when a charging time for said vehicle by said charging means is a predetermined time or shorter than the predetermined time, said vehicle is charged with electricity from said rechargeable means.   
     
     
         2 . The charging control system according to  claim 1 ,
 wherein said charging control means controls charging such that when the charging for said vehicle by said charging means is longer than the predetermined time, said rechargeable means is charged with electricity by said charging means based on a state of stored electricity of said rechargeable means.   
     
     
         3 . The charging control system according to  claim 1 , further comprising:
 charging scheduling means that performs scheduling in which said charging means charges said vehicle based on an electric power demand that causes said charging means to charge said vehicle with electricity.   
     
     
         4 . A charging control system that controls charging for a vehicle that runs on electricity, comprising:
 at least one rechargeable means;   charging means that charges said vehicle or said rechargeable means with electricity;   charging scheduling means that performs scheduling in which said charging means charges said vehicle based on an electric power demand that causes said charging means to charge said vehicle with electricity; and   charging control means that controls charging such that when a charging time for said vehicle cannot be predicted, said vehicle is charged with electricity from said rechargeable means.   
     
     
         5 . A charging control method for a charging control system, including: at least one rechargeable means; and charging means that charges a vehicle that runs on electricity, said method comprising:
 controlling charging such that when a charging time for said vehicle by said charging means is a predetermined time or shorter than the predetermined time, said vehicle is charged with electricity from said rechargeable means.
