A power monitoring and control apparatus (102,502) and system are provided, which level charge loads of electric vehicles over an overall power system (101) as well as make the power loads fall within the maximum contract power, in plug-in charging of the electric vehicles in individual houses. The power monitoring and control apparatus is used in charging a battery-mounted equipment (108) from the power system through a battery charger (106). The apparatus (104,105; 504, 505) compares a current value available for charging the battery-mounted equipment from the power system with a charging current value requested to the battery charger from the battery-mounted equipment, and employs as the charging current to the battery-mounted equipment a smaller one among the charging current available value and the charging request value. |
