Regeneration control device of electrically powered vehicle

A regeneration control device of an electrically powered vehicle, comprising:

• a motor generator configured to perform electric power regeneration by braking a driving wheel of the electrically powered vehicle;
• a battery to which electric power regenerated by the motor generator is supplied;
• monitoring means including at least one of charging rate detection means configured to detect a charging rate of the battery and voltage value detection means configured to detect a voltage value of the battery;
• and
• control means configured to control the electric power regeneration of the motor generator according to at least one of the charging rate and the voltage value of the battery detected by the monitoring means,
• wherein the control means is configured to decrease regenerative electric current of the motor generator as at least one of the charging rate and the voltage value is increased, and
• wherein the control means is configured to perform a series of regenerative controls by performing the electric power regeneration a plurality of times, and a value of the regenerative electric current during a succeeding regenerative control is set smaller than a value of the regenerative electric current during a preceding regenerative control.
