A propulsion control apparatus for an electric motor car includes: an inverter apparatus connected to a DC power supply; a motor connected to an output of the inverter apparatus; a converter apparatus connected to an input of the inverter apparatus; and a power storage apparatus connected to an output of the converter apparatus. The propulsion control apparatus for an electric motor car is configured to discharge a part of power running power or regenerative power of the motor from the power storage apparatus or charge a part of the power running power or the regenerative power in the power storage apparatus. The converter apparatus includes a converter control unit that generates, based on a regeneration state signal as a signal indicating a suppression state of the regenerative power or regenerative torque or regenerative current equivalent to the regenerative power, a charging current command value, which is a command value of an electric current with which the converter apparatus charges the power storage apparatus, generates a charging and discharging current command value of the converter apparatus based on the charging current command value, and performs control.
