REGENERATION CONTROL DEVICE OF ELECTRIC VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a regeneration control device of an electric vehicle which suppresses large variation of regenerative current and regenerative torque during regenerative braking when battery voltage rises up to the vicinity of the upper limit.

SOLUTION: In this regeneration control device of an electric vehicle which controls regenerative power generation of a motor generator when the battery voltage of a battery device reaches the upper-limit value, an SOC (state of charge) of the battery device is monitored (S1); regenerative current to be carried to the battery device is calculated from a map based on the SOC (S2); and regenerative torque is controlled so as not to exceed the calculated regenerative current (S3).
