<p>A controlling method for battery charge of electric vehicle, wherein upon start of charging, a current charged state of a battery is grasped to calculate an anticipated input current up until the completion of the battery charging and degree of undercharged state is grasped in consideration of current battery aging to overcharge the battery as much as the undercharge, thereby preventing a battery performance degradation caused by the continuous undercharging, and a battery aging state in consideration of battery cycling is discriminated to increase a calculation accuracy of battery charging state and to thereby improve a running distance of the electric vehicle by maintaining an initial vehicle state, the method comprising the steps of receiving a battery charge state before starting battery charge to calculate an anticipated current for charging and to output a control signal for charging a battery according to a priorly established charge control program; discriminating whether the charge has been completed after the charge is started; comparing the anticipated charge current with an actually charged current to discriminate whether the actually charged current is larger than the anticipated charge current if it is discriminated that the charge is completed; terminating the charge if it is discriminated that the actually charged current is larger than the anticipated charge current. <IMAGE></p> |
