Abstract
A charging and discharging control device includes a pantograph point voltage detection unit configured to detect a pantograph point voltage of a vehicle, a charging and discharging control unit configured to charge a power storage device provided in a vehicle when the pantograph point voltage is greater than or equal to a charging voltage threshold value and discharge the power storage device when the pantograph point voltage is less than a discharging voltage threshold value, a load determination unit configured to determine whether an absolute value of load power for the vehicle is less than a load power threshold value, and a charging and discharging control change unit configured to reduce any one or more of the charging voltage threshold value, the discharging voltage threshold value, and charging/discharging impedance when the absolute value of the load power is less than the load power threshold value.
